Description

Die Erfindung betrifft ein Bürstwerkzeug gemäß dem Oberbegriff des Patentanspruches 1 sowie eine mit einem solchen Bürstwerkzeug bestückte Werkzeugmaschine.The invention relates to a brushing tool according to the preamble of claim 1 and a stocked with such a brushing machine tool.

Derartige Bürstwerkzeuge werden zur Oberflächenbehandlung von Werkstücken verwendet, wie zum Beispiel dem Reinigen oder Entgraten von Werkstücken, an welchen durch einen vorausgegangenen mechanischen Arbeitsprozess, etwa einem Schneide-, Fräs- oder Bohrprozess, Grate oder scharfe Kanten und damit verbundene Verunreinigungen entstanden sind.Such brushing tools are used for surface treatment of workpieces, such as, for example, the cleaning or deburring of workpieces on which burrs or sharp edges and associated contaminants have been created by a preceding mechanical working process, such as a cutting, milling or drilling process.

Aus der Gebrauchsmusterschrift DE 201 02 690 U1 ist eine Entgrateinrichtung mit wenigstens einem Bürstwerkzeug bekannt, das eine rotierende Trägerplatte aufweist, in der wenigstens eine Bürste gehalten und axial oder in einem Winkel zur Rotationsachse der Trägerplatte angeordnet ist. Weiterhin weist das Bürstwerkzeug wenigstens eine beabstandet und verdrehfest zur Trägerplatte angeordnete Führungsplatte auf, durch die die wenigstens eine Bürste mit ihren frei austretenden Borsten geführt ist.From the utility model DE 201 02 690 U1 a deburring device with at least one brushing tool is known, which has a rotating support plate in which at least one brush is held and arranged axially or at an angle to the axis of rotation of the support plate. Furthermore, the brushing tool has at least one spaced apart and rotationally fixed to the support plate guide plate, through which the at least one brush is guided with their freely emerging bristles.

Das bekannte Bürstwerkzeug sitzt auf einem verstellbaren Schlitten und ist fester Teil der Entgrateinrichtung. Bei derartigen Entgrateinrichtungen handelt es sich jedoch um kostspielige Einzelanfertigungen des Spezialmaschinenbaus, deren Anschaffung sich nur in der Großserienfertigung rentieren, wo eine Vielzahl an Werkstücken bearbeitet werden und der Platz für eine solche Sondermaschine in der Fertigungsstraße vorhanden ist.The known brushing tool sits on an adjustable carriage and is a fixed part of the deburring device. However, such deburring devices are costly one-offs of special machine construction, the purchase of which is profitable only in mass production, where a large number of workpieces are processed and the space for such a special machine is present in the production line.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Bürstwerkzeug der eingangs genannten Art bereitzustellen, welches auch ohne den hohen Investitionsaufwand einer vollständigen Entgratmaschine einsetzbar ist.The invention is therefore based on the object to provide a brushing tool of the type mentioned, which can be used without the high investment cost of a complete deburring machine.

Erfindungsgemäß wird die Aufgabe gelöst durch ein gattungsgemäßes Bürstwerkzeug mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1. Indem die Trägerplatte und die Führungsscheibe drehfest mit einer eine Rotationsachse aufweisenden Aufnahmeeinrichtung verbunden sind, welche zur auswechselbaren Kupplung mit einer Antriebseinrichtung vorgesehen ist, wird ein Bürstwerkzeug zum Entgraten und/oder Reinigen von bearbeiteten Werkstücken bereitgestellt, welches in sämtlichen Werkzeugmaschinen zum Einsatz kommen kann, die eine geeignete Schnittstelle zwischen ihrer Antriebseinrichtung und der Aufnahmeeinrichtung des Bürstwerkzeugs aufweisen. Die Vielseitigkeit der Verwendung des Bürstwerkzeugs wird dabei über die Gestaltung seiner Aufnahmeeinrichtung, das heißt deren maschinenseitigen Anteils, bestimmt. Das Bürstwerkzeug kann dabei mehrere auf einem Teilkreis um seine Rotationsachse verteilt angeordnete Borstenbündel in Form einer Topfbürste aufweisen.According to the invention the object is achieved by a generic brushing tool with the features of the characterizing part of claim 1. By the support plate and the guide disc rotatably connected to a rotation axis having a receiving device, which is provided for interchangeable coupling with a drive means, a brushing tool for deburring and / or cleaning of machined workpieces, which can be used in all machine tools that have a suitable interface between their drive device and the receiving device of the brushing tool. The versatility of the use of the brushing tool is determined by the design of its receiving device, that is, the machine-side share. The brushing tool can in this case have a plurality of bristle bundles distributed in the form of a cup brush arranged distributed on a pitch circle around its axis of rotation.

In einer bevorzugten Ausgestaltung des erfindungsgemäßen Bürstwerkzeugs weist die Aufnahmeeinrichtung einen Kegelabschnitt auf, der zum Festspannen in der Antriebseinrichtung vorgesehen ist. Mit Vorteil können hier standardisierte Flächenspannfutter mit Kegelschaft zur Aufnahme des Bürstwerkzeugs in der Antriebseinrichtung verwendet werden. Es stehen damit bereits genormte Schnittstellen zwischen Werkzeugen und einer Werkzeugmaschine, insbesondere deren Antrieb, zur Verfügung.In a preferred embodiment of the brushing tool according to the invention, the receiving device has a conical section, which is provided for clamping in the drive device. Advantageously, standardized surface chucks with conical shank can be used here for receiving the brushing tool in the drive device. Thus, standardized interfaces between tools and a machine tool, in particular their drive, are already available.

In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Bürstwerkzeugs weist die Aufnahmeeinrichtung einen Greifbund mit ringförmiger Nut auf. In die Nut des Greifbundes kann ein Geifarm einer Werkzeugmaschine ansetzen, um das Bürstwerkzeug zu fassen und dieses automatisch etwa gegen ein anderes Werkzeug auszutauschen.In an advantageous embodiment of the brushing tool according to the invention, the receiving device has a gripping collar with an annular groove. Into the groove of the gripping collar can attach a Geifarm a machine tool to grasp the brushing tool and automatically replace this for another tool.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Bürstwerkzeugs weist die Aufnahmeeinrichtung eine Verstelleinrichtung auf, mittels der die Trägerplatte relativ zur Führungsscheibe längs der Rotationsachse verschiebbar ist. Hierdurch kann bei vorgegebenem Abstand der Führungsscheibe zur Oberfläche des Werkstückes die Trägerplatte mit den darin festgeklemmten Borstenbündeln unabhängig von der Führungsscheibe zugestellt werden. Dies ermöglicht einen Ausgleich des Verschleißes der Borstenbündel durch axiale Zustellung in Richtung Werkstück.In a preferred embodiment of the brushing tool according to the invention, the receiving device has an adjusting device, by means of which the carrier plate relative to Guide disk is displaceable along the axis of rotation. In this way, the support plate can be delivered with the bristle bundles clamped therein regardless of the guide disc at a given distance of the guide disc to the surface of the workpiece. This allows a compensation of the wear of the bristle bundles by axial feed towards the workpiece.

In einer vorteilhaften Ausführungsform des erfindungsgemäßen Bürstwerkzeugs ist die Verstelleinrichtung als Gewindeverbindung ausgebildet. Über die Steigung der Gewindeverbindung wird eine Drehbewegung in eine Axialbewegung der Trägerplatte umgesetzt, wodurch sich die Zustellbewegung mit hoher Genauigkeit vornehmen lässt.In an advantageous embodiment of the brushing tool according to the invention, the adjusting device is designed as a threaded connection. About the pitch of the threaded connection a rotational movement is converted into an axial movement of the support plate, whereby the feed movement can be made with high accuracy.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Bürstwerkzeugs weist die Verstelleinrichtung Feststellmittel zur Fixierung einer eingestellten Lage der Trägerplatte aufweist. Hierdurch kann ein eingestellter Borstenüberstand gehalten werden, da die Trägerplatte gegen Verstellung etwa durch den Bearbeitungsprozess gesichert ist. Dies gestattet eine reproduzierbar hohe Bearbeitungsqualität.In a further preferred embodiment of the brushing tool according to the invention, the adjusting device has locking means for fixing a set position of the carrier plate. In this way, a set bristle projection can be kept, since the support plate is secured against adjustment, for example by the machining process. This allows a reproducible high processing quality.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Bürstwerkzeugs ist zwischen Trägerplatte und Führungsscheibe eine die Aufnahmeeinrichtung umschließende Schmutzabdeckung angeordnet ist. Mit Vorteil passt sich die Schmutzabdeckung dem jeweils eingestellten Abstand zwischen Trägerplatte und Führungsscheibe an. So kann die Schmutzabdeckung als Kegelstumpffeder in Form einer kegeligen Schraubendruckfeder aus Band mit rechteckigem Querschnitt ausgebildet sein. Sie schützt beispielsweise die Gewindeverbindung der Verstelleinrichtung vor Verunreinigungen durch den entstandenen Bearbeitungsabrieb oder von zugeführtem Kühl- oder Schmiermittel.In a further advantageous embodiment of the brushing tool according to the invention, a dirt cover enclosing the receiving device is arranged between the carrier plate and the guide plate. Advantageously, the dirt cover adapts to the respectively set distance between carrier plate and guide plate. Thus, the dirt cover may be formed as a truncated cone spring in the form of a conical helical compression spring made of strip with a rectangular cross-section. It protects, for example, the threaded connection of the adjusting device against contamination by the resulting machining abrasion or supplied coolant or lubricant.

In einer anderen bevorzugten Ausgestaltung des erfindungsgemäßen Bürstwerkzeugs verläuft ein Kanalsystem für die Zuführung von Kühl- und/oder Schmiermittel durch die Aufnahmeeinrichtung und durch die Trägerplatte und/oder Führungsscheibe und mündet direkt an dem mindestens einen Borstenbündel. Hierdurch kann Kühl- und/oder Schmiermittel von innen direkt an den Ort der Wärmeentwicklung beim Bürstvorgang gebracht werden. Durch die Zuführung von Kühl- und/oder Schmiermittel innerhalb der Führungsscheibe wird diese direkt gekühlt. Dies ist insbesondere bei der Bearbeitung von Mangan-haltigen Werkstücken wichtig, da die dabei auftretende Wärmeentwicklung eine Brandgefahr darstellt. Neben der erhöhten Prozesssicherheit durch ein Nassbürsten werden auch wesentlich höhere Standzeiten des Bürstwerkzeugs erzielt. Dadurch erfolgt eine Verbesserung etwa von Entgratergebnisse, da die Verrundungen gleichmäßiger sind und die Oberflächengüte besser. Dies führt wiederum zu einer Verbesserung der Abtragleistung sowie zu kürzeren Durchlaufzeiten der Werkstücke.In another preferred embodiment of the brushing tool according to the invention runs a channel system for the supply of coolant and / or lubricant through the receiving device and through the support plate and / or guide disc and opens directly to the at least one bristle bundle. As a result, coolant and / or lubricant can be brought from the inside directly to the place of heat generation during the brushing process. The supply of coolant and / or lubricant within the guide disc, this is cooled directly. This is particularly important in the processing of manganese-containing workpieces, since the resulting heat generation represents a fire hazard. In addition to the increased process reliability through wet brushing, significantly longer service lives of the brushing tool are achieved. This results in an improvement of deburring results, for example, since the fillets are more uniform and the surface finish is better. This in turn leads to an improvement in the removal rate as well as to shorter throughput times of the workpieces.

Vorzugsweise weist das Kanalsystem des erfindungsgemäßen Bürstwerkzeugs in der Führungsscheibe einen zentralen Verteilerraum und von diesem zu je einer Mündung an einem Borstenbündel verlaufende Radialkanäle auf. Bei einer Vielzahl an Borstenbündeln wird die Wärmeabfuhr dadurch erreicht, dass der Führungsscheibe in den zentralen Verteilerraum Kühl- und/oder Schmiermittel zugeführt wird und dieses dann durch die Rotationsbewegung als Folge der Zentrifugalkraft durch die Radialkanäle, die an je einem Borstenbündel münden, zugeführt. Dadurch wird Kühl- und/oder Schmiermittel genau an den Ort der Wärmeentstehung gebracht. Außerdem wird die Führungsscheibe flächig durch ein sternförmiges Muster an Radialkanälen gekühlt.The channel system of the brushing tool according to the invention preferably has a central distributor space in the guide disk and radial channels extending therefrom to an orifice on a bundle of bristles. In the case of a multiplicity of bundles of bristles, heat dissipation is achieved by supplying coolant and / or lubricant to the guide disk in the central distributor space and then supplying it by the rotational movement as a result of the centrifugal force through the radial channels which each lead to a bristle bundle. As a result, coolant and / or lubricant is brought exactly to the place of heat generation. In addition, the guide plate is cooled flat by a star-shaped pattern of radial channels.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Bürstwerkzeugs weist das Kanalsystem einen in der Aufnahmeeinrichtung verlaufenden Axialkanal auf, der in den zentralen Verteilerraum mündet. Aufnahmeeinrichtungen in standardisierter Ausführung sind ebenfalls mit einem Axialkanal verfügbar, in den etwa von einem Reservoir einer Werkzeugmaschine Kühl- und/oder Schmiermittel zuführbar ist.In a preferred embodiment of the brushing tool according to the invention, the channel system has an axial channel running in the receiving device, which opens into the central distributor chamber. Receiving devices in a standardized version are also available with an axial channel, in which about from a reservoir of a machine tool coolant and / or lubricant can be fed.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Bürstwerkzeugs ist mindestens eine der Mündungen eines der Radialkanäle an einer der Rotationsachse zugewandten Seite des Borstenbündels angeordnet. Indem die Mündungen an den Innenseiten der Borstenbündel angeordnet sind, wird das Kühl- und/oder Schmiermittel durch die Fliehkraft im Betrieb des Bürstwerkzeugs in das Borstenbündel hineingedrückt und kann von dort zu den freien Enden der Borsten ablaufen, um so an die Bearbeitungsfläche am Werkstück zu gelangen.In a further advantageous embodiment of the brushing tool according to the invention, at least one of the orifices of one of the radial channels is arranged on a side of the bristle bundle facing the axis of rotation. By the mouths are arranged on the inner sides of the bristle bundles, the coolant and / or lubricant is pressed by the centrifugal force in the operation of the brushing tool in the bristle bundle and can run from there to the free ends of the bristles so as to the working surface on the workpiece reach.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Bürstwerkzeugs weist die Führungsscheibe einen Grundkörper mit Bohrungen zur Durchführung je eines Borstenbündels und eine Deckplatte auf, wobei die Radialkanäle durch sich im Grundkörper radial erstreckende Nuten und durch die diese lateral verschließende Deckplatte gebildet sind. Hierdurch wird eine besonders kostengünstige und einfache Konstruktion und Fertigung der Führungsscheibe mit Radialkanälen bereitgestellt.In a further preferred embodiment of the brushing tool according to the invention, the guide disk has a base body with holes for the passage of a bristle bundle and a cover plate, wherein the radial channels are formed by grooves extending radially in the base body and by the cover plate closing the latter laterally. As a result, a particularly inexpensive and simple construction and manufacture of the guide plate is provided with radial channels.

Ferner ist mit Vorteil eine Werkzeugmaschine zur Bearbeitung eines Werkstückes, welche eine Antriebseinrichtung zur Ausführung einer rotatorischen und/oder translatorischen Vorschubbewegung umfasst, derart mit einem erfindungsgemäßen Bürstwerkzeug gekuppelt, dass die Führungsscheibe in einem konstanten Abstand zum zu bearbeitenden Werkstück haltbar ist. Beim Einsatz in solchen Universal-Werkzeugmaschinen wird deren Vorrat an Werkzeugen um das erfindungsgemäße Bürstwerkzeug bereichert, was deren Bearbeitungsvielfalt erhöht. Typischerweise ist das Werkzeug in einer Spannvorrichtung festgehalten, gegenüber der das Bürstwerkzeug die Vorschubbewegungen ausführt. Durch den konstanten gehaltenen Abstand der Führungsscheibe zur Werkstückoberfläche wird ein gleich bleibender Borstenüberstand und damit ein konstantes Bearbeitungsergebnis erreicht.Furthermore, a machine tool for machining a workpiece, which comprises a drive device for carrying out a rotary and / or translatory feed movement, is coupled with a brushing tool according to the invention in such a manner that the guide plate is durable at a constant distance from the workpiece to be machined.

Vorzugsweise umfasst die Werkzeugmaschine ein Reservoir an unterschiedlichen Werkzeugen für die Bearbeitung eines Werkstückes und ist zum automatischen Auswechseln von Werkzeugen zwischen zwei Bearbeitungsvorgängen ausgebildet. Ein Werkstück kann damit von ein und derselben Maschine zunächst durch den Einsatz von Fräs- oder Bohrwerkzeugen und anschließend mittels eines erfindungsgemäßen Bürstwerkzeuges bearbeitet werden, und zwar ohne Maschinenwechsel und ohne manuellen Werkzeugwechsel.Preferably, the machine tool comprises a reservoir of different tools for machining a workpiece and is designed for automatic replacement of tools between two machining operations. A workpiece can thus be processed by one and the same machine first by the use of milling or drilling tools and then by means of a Bürstwerkzeuges invention, without machine change and without manual tool change.

In einer vorteilhaften Ausführungsvariante ist die Werkzeugmaschine als Industrieroboter ausgebildet. Beispielweise kann an der sechsten Achse des Roboters die Aufnahmeeinrichtung des erfindungsgemäßen Bürstwerkzeugs um die Rotationsachse drehbar eingespannt sein, wobei ein Getriebemotor als Antriebseinrichtung angeflanscht ist.In an advantageous embodiment, the machine tool is designed as an industrial robot.

Gemäß FIG 1 bis FIG 4 weist ein Bürstwerkzeug 10 eine Vielzahl von Borstenbündeln 20 - beispielsweise achtzehn - auf, die auf einem Teilkreis gleichmäßig verteilt in eine Trägerplatte 30 mit ihrem oberen Ende eingespannt sind. Die Borstenbündel 20 werden paarweise durch kreissegmentförmige Klemmelemente 31 gehalten, die mittels Klemmschrauben 32 von außen an der Trägerplatte 30 befestigt sind. Ein Borstenbündel 20 besteht aus einer Vielzahl an Borsten, beispielsweise aus Nylon, die an ihrem einen Ende pinselartig zu einem Bündel zusammengebunden sind. Die freien Enden der Borstenbündel 20 sind durch Bohrungen 43 einer zur Trägerplatte 30 beabstandeten Führungsscheibe 40 geführt und bilden einen aus der Führungsscheibe 40 heraus stehenden Überstand.According to FIG. 1 to FIG. 4, a brushing tool 10 has a multiplicity of bristle bundles 20-for example eighteen-which are uniformly distributed on a graduated circle and clamped in a carrier plate 30 with its upper end. The bristle bundles 20 are paired by circular segment Clamping elements 31 held, which are fastened by means of clamping screws 32 from the outside to the support plate 30. A bundle of bristles 20 consists of a multiplicity of bristles, for example of nylon, which are brushed together at their one end into a bundle. The free ends of the bristle bundles 20 are guided through holes 43 of a guide plate 40 spaced from the carrier plate 30 and form a projection projecting out of the guide plate 40.

Die Trägerplatte 30 und die Führungsscheibe 40 sind drehfest mit einer rotationssymmetrischen Aufnahmeeinrichtung 50 verbunden, welche eine Rotationsachse R definiert. Die Trägerplatte 30 weist ein zentrisches Durchgangsloch auf und ist über einen zylindrischen Bürstenabschnitt 52 der Aufnahmeeinrichtung 50 geschoben, während die Führungsscheibe 40 an der Stirnfläche des Bürstenabschnittes 52 befestigt ist. Die Aufnahmeeinrichtung 50 weist an ihrem dem Bürstenabschnitt 52 abgewandten Ende einen Kegelabschnitt 51 auf, der zum Festspannen des Bürstwerkzeugs 10 und damit zur dessen Kupplung mit einer nicht dargestellten Antriebseinrichtung beispielsweise einer Werkzeugmaschine vorgesehen ist. Mit Vorteil werden hier Standard-Flächenspannfutter nach DIN 69871 A mit Kegelschaft nach DIN 2080 AT 3 zur Aufnahme in der Antriebseinrichtung verwendet. Das Bürstwerkzeug 10 führt im Betrieb eine rotatorische Vorschubbewegung VR um die Rotationsachse R aus. Zusätzlich kann dieses eine translatorische Vorschubbewegung VT relativ zum zu bearbeitenden Werkstück W überlagert werden. Beim Vorschub streifen die freien Enden der Borstenbündel 20 über die Oberfläche des Werkstückes W und runden dabei vorhandene Grate und scharfe Kanten ab oder entfernen Verunreinigungen. Die Aufnahmeeinrichtung 50 weist zwischen dem Kegelabschnitt 51 und dem Bürstenabschnitt 52 einen Greifbund 54 auf, in dem eine ringförmige Nut eingearbeitet ist. In diese Nut mit trapezförmigem Querschnitt kann ein Greiforgan einer Werkzeugmaschine ansetzen, um einen automatischen Werkzeugwechsel vorzunehmen.The carrier plate 30 and the guide plate 40 are rotatably connected to a rotationally symmetrical receiving device 50, which defines a rotation axis R. The support plate 30 has a central through-hole and is slid over a cylindrical brush portion 52 of the receiver 50, while the guide washer 40 is fixed to the end surface of the brush portion 52. The receiving device 50 has at its end facing away from the brush portion 52 a conical portion 51 which is provided for clamping the brush tool 10 and thus for the coupling with a drive device, not shown, for example, a machine tool. Advantageously, here standard surface chuck DIN 69871 A with taper shank according to DIN 2080 AT 3 are used for receiving in the drive device. During operation, the brushing tool 10 executes a rotary feed movement V R about the axis of rotation R. In addition, this can be superimposed on a translational feed movement V T relative to the workpiece W to be machined. When feeding the free ends of the bristle bundles 20 over the surface of the workpiece W and thereby round existing burrs and sharp edges or remove impurities. The receiving device 50 has between the cone portion 51 and the brush portion 52 a gripping collar 54, in which an annular groove is incorporated. In this groove with trapezoidal cross-section can attach a gripping member of a machine tool to make an automatic tool change.

Damit zwischen Führungsscheibe 40 und Werkstück W stets ein optimaler Borstenüberstand vorliegt, weist die Aufnahmeeinrichtung 50 eine Verstelleinrichtung 60 bzw. 70 auf, mittels der die Trägerplatte 30 relativ zur Führungsscheibe 40 längs der Rotationsachse R verschiebbar ist. Tritt ein Verschleiß der Borsten auf, so kann über die Verstelleinrichtung 60 bzw. 70 eine Zustellbewegung Z der Borstenbündel 20 vorgenommen werden, um so den für ein optimales Bearbeitungsergebnis erforderlichen Borstenüberstand von etwa 18 bis 20 mm wieder herzustellen.So that there is always an optimum bristle projection between guide plate 40 and workpiece W, the receiving device 50 has an adjusting device 60 or 70, by means of which the carrier plate 30 is displaceable relative to the guide plate 40 along the axis of rotation R. If wear of the bristles occurs, an advancing movement Z of the bristle bundles 20 can be made via the adjusting device 60 or 70 so as to restore the bristle projection of about 18 to 20 mm required for an optimum processing result.

In einer ersten Ausführungsvariante gemäß FIG 1 weist die Aufnahmeeinrichtung 50 im Bürstenabschnitt 52 eine achsparallele Nut 53 auf, in die eine Passfeder 67 formschlüssig eingreift. Die Passfeder 67 ist mit der Trägerplatte 30 mittels einer Schraube 66 fest verbunden, wodurch die Trägerplatte 30 ihre drehfeste aber längs der Rotationsachse R verschiebbare Verbindung mit dem Bürstenabschnitt 52 erlangt. Die Verstelleinrichtung 60 umfasst eine Verstellmutter 61, die auf einen entsprechenden Gewindeabschnitt 56 des Bürstenabschnittes 52 aufgeschraubt ist. Auf die Trägerplatte 30 ist mittels Befestigungsmitteln 65 eine Kupplungsplatte 64 befestigt, die einen ringförmigen Steg aufweist. Mit ihrem Steg greift die Kupplungsplatte in eine ringsförmige Nut der Verstellmutter 61 ein, sodass die axiale Bewegung der Verstellmutter 61 bei deren Verdrehen über die Kupplungsplatte 64 auf die Trägerplatte 30 übertragen wird. Dabei bewegt sich die Passfeder 67 längs der Nut 53. Zur Fixierung eines eingestellten Borstenüberstandes ist auf den Gewindeabschnitt 56 eine Feststellmutter 62 benachbart zur Verstellmutter 61 aufgeschraubt. Durch Feststellschrauben 63 werden die Muttern 62, 63 axial gegeneinander verspannt, sodass sie sich nicht von selbst lösen können. Alternativ können die Verstellmutter und die Feststellmutter auch einteilig ausgebildet sein; solche einteiligen Stellmuttern sind im Handel erhältlich.In a first embodiment variant according to FIG. 1, the receiving device 50 has an axially parallel groove 53 in the brush section 52 into which a feather key 67 engages in a form-fitting manner. The feather key 67 is fixedly connected to the carrier plate 30 by means of a screw 66, whereby the carrier plate 30 attains its non-rotatable but slidable connection with the brush portion 52 along the axis of rotation R. The adjusting device 60 comprises an adjusting nut 61, which is screwed onto a corresponding threaded portion 56 of the brush portion 52. On the support plate 30, a coupling plate 64 is fastened by means of fastening means 65, which has an annular web. With its web, the coupling plate engages in an annular groove of the adjusting nut 61, so that the axial movement of the adjusting nut 61 is transmitted to the carrier plate 30 via the coupling plate 64 during its rotation. In this case, the key 67 moves along the groove 53. To fix a set bristle projection on the threaded portion 56, a locking nut 62 is screwed adjacent to the adjusting nut 61. By locking screws 63, the nuts 62, 63 axially braced against each other, so they can not solve by themselves. Alternatively, the adjusting nut and the locking nut can also be integrally formed; such one-piece locknuts are commercially available.

In einer zweiten Ausführungsvariante gemäß FIG 2 und 3 weist die Aufnahmeeinrichtung 50 im Bürstenabschnitt 52 drei achsparallele und im 120°-Abstand zueinander angeordnete Nuten 53 auf, in die je eine Passfeder 77 formschlüssig eingreift. Die Passfedern 77 sind mit der Trägerplatte 30 über in Radialbohrungen 33 eingeführte Schrauben 76 fest verbunden, wodurch die Trägerplatte 30 ihre drehfeste aber längs der Rotationsachse R verschiebbare Verbindung mit dem Bürstenabschnitt 52 erlangt. Die Verstelleinrichtung 70 umfasst eine Verstellmutter 71 mit Innengewinde, die in eine stirnseitige Axialbohrung 55 in den Bürstenabschnitt 52 etwa durch Einspressen festgesetzt ist. Die Verstellmutter 71 weist an ihrem Umfang drei achsparallele Nuten auf, in die die Passfedern 77 eingreifen, wobei die durch die Passfedern 77 geführten Schrauben 76 bis in die Verstellmutter 71 eingreifen. In das Innengewinde der Verstellmutter 71 ist eine durch die Führungsscheibe 40 in die Axialbohrung 55 geführte Bundschraube 72 eingedreht. An ihrem Bund ist die Bundschraube 72 durch Feststellmittel 75 gegen axiale Verschiebung und gegen selbsttätiges Drehen gesichert. Die Feststellmittel 75 können als O-Ring oder Kunststoffeinlage ausgebildet sein. Ein aktives Drehen der Bundschraube 72 bewirkt eine axiale Verschiebung der Verstellmutter 71 und damit der Trägerplatte 30 mit ihren Borstenbündeln 20.In a second embodiment according to FIGS 2 and 3, the receiving device 50 in the brush portion 52 three axially parallel and in the 120 ° distance to each other arranged grooves 53, in each of which a key 77 engages positively. The feather keys 77 are fixedly connected to the carrier plate 30 via screws 76 inserted in radial bores 33, whereby the carrier plate 30 acquires its non-rotatable but slidable connection with the brush section 52 along the axis of rotation R. The adjusting device 70 comprises an adjusting nut 71 with internal thread, which is fixed in an end-side axial bore 55 in the brush portion 52 as by injection. The adjusting nut 71 has on its circumference three axially parallel grooves into which the feather keys 77 engage, wherein the guided by the feather keys 77 screws 76 engage in the adjusting nut 71. In the internal thread of the adjusting nut 71 guided through the guide plate 40 into the axial bore 55 collar screw 72 is screwed. At its collar, the collar screw 72 is secured by locking means 75 against axial displacement and against automatic rotation. The locking means 75 may be formed as an O-ring or plastic insert. An active rotation of the collar screw 72 causes an axial displacement of the adjusting nut 71 and thus the support plate 30 with their bristle bundles 20th

In beiden Ausführungsvarianten ist gemäß FIG 1 und FIG 2 zwischen Trägerplatte 30 und Führungsscheibe 40 eine den Bürstenabschnitt 52 der Aufnahmeeinrichtung 50 wenigstens teilweise umschließende Schmutzabdeckung 80 angeordnet. Die Schmutzabdeckung ist als Kegelstumpffeder aus Band ausgeführt und passt sich so dem jeweils eingestellten Abstand zwischen Trägerplatte 30 und Führungsscheibe 40 an. Sie schützt beispielsweise die Gewindeverbindung der Verstelleinrichtung 60 bzw. 70 vor Verunreinigungen durch den entstandenen Bearbeitungsabrieb oder vor zugeführtem Kühl- und/oder Schmiermittel.In both embodiments, as shown in FIG 1 and FIG 2 between the support plate 30 and guide plate 40, a brush portion 52 of the receiving device 50 at least partially enclosing dirt cover 80 is arranged. The dirt cover is designed as a truncated cone spring made of tape and thus adapts to the respectively set distance between the carrier plate 30 and guide plate 40. It protects, for example, the threaded connection of the adjusting device 60 or 70 against contamination by the resulting machining abrasion or before supplied coolant and / or lubricant.

Um die beim Bürstprozess entstehenden Wärme abzutransportieren weist das Bürstwerkzeug in der Ausführungsvariante nach FIG 1 ein Kanalsystem 90 für die Zuführung von Kühl- und/ oder Schmiermittel K/S auf. Gemäß FIG 4 führt ein Axialkanal 91 innerhalb der Aufnahmeeinrichtung 50, der in einen zentralen Verteilerraum 92 in der Führungsscheibe 40 mündet. Am in der Führungsscheibe 40 durch Befestigungsschrauben 57 verankerten, unteren Ende der Aufnahmeeinrichtung 50 schließen sich innerhalb der Führungsscheibe 40 verlaufende Radialkanäle 93 an, die durch sich in einem Grundkörper 41 der Führungsscheibe 40 radial erstreckende Nuten 42 und durch die diese lateral von oben verschließende Deckplatte 44 gebildet sind. Das Kühl- und/oder Schmiermittel K/S wird durch die Zentrifugalkraft nach außen getrieben, wo es durch die Mündungen 94 aus den Radialkanälen 93 austritt und an die durch die Bohrungen 43 der Führungsscheibe 40 geführten Borstenbündel 20 gelangt. Damit steht das Kühl- und/oder Schmiermittel K/S direkt an dem Ort zur Verfügung, an welchem die prozessbedingte Wärmeentwicklung stattfindet.In order to remove the heat generated during the brushing process, the brushing tool in the embodiment according to FIG. 1 has a channel system 90 for the supply of cooling and / or cooling Lubricant K / S on. According to FIG. 4, an axial channel 91 leads within the receiving device 50, which opens into a central distributor chamber 92 in the guide plate 40. At the lower end of the receiving device 50 anchored in the guide disk 40 by fastening screws 57, radial channels 93 extend inside the guide disk 40 and extend radially through grooves 42 in a base body 41 of the guide disk 42 and through the cover plate 44 closing laterally from above are formed. The coolant and / or lubricant K / S is driven outwards by the centrifugal force, where it exits the radial passages 93 through the orifices 94 and reaches the bristle bundles 20 guided through the bores 43 of the guide disk 40. Thus, the coolant and / or lubricant K / S is available directly at the place where the process-related heat development takes place.

Die Kühl- und/oder Schmiermittelversorgung erfolgt von innen, d.h. die Kühlung bzw. die Schmierstoffversorgung findet an optimaler Stelle statt. Dies führt zu einer verbesserten Wärmeabfuhr und dadurch zu einer höheren Prozesssicherheit. Es können wesentlich höhere Standzeiten des Bürstwerkzeugs erreicht werden. Es werden verbesserte Entgratergebnisse in Form von einer gleichmäßigen Verrundung und einer verbesserten Oberflächengüte erreicht. Dies führt schließlich zu einer Verbesserung der Abtragleistung und zu kürzeren Durchlaufzeiten der Werkstücke.The supply of coolant and / or lubricant takes place from the inside, i. the cooling or the lubricant supply takes place at the optimum place. This leads to an improved heat dissipation and thereby to a higher process reliability. Significantly longer service lives of the brushing tool can be achieved. Improved deburring results in the form of a uniform fillet and improved surface finish are achieved. This eventually leads to an improvement in the removal rate and to shorter throughput times of the workpieces.
