Definitions
- the present invention relates to a tool for clamping together pivotable parts under bias relative to each other.
- the invention also relates to a swing bolt construction with integrated locking, as for instance applied in said tool.
- Hydraulic shears are an example of such a tool. This is understood to mean, among others, shears with a sufficient cutting force for cutting open objects such as motor vehicles, trains, boats and the like, for instance in the case of vehicle accidents, search and rescue operations in an urban environment, industrial applications and rail accidents.
- the pivotable parts (also referred to as blades) of the shears are displaced by means of an externally or internally driven hydraulic cylinder, and a very great cutting force can hereby be exerted on the relevant object.
- Another example of such a tool is a hydraulic spreader with which parts of an object can be pressed apart.
- Another example of such a tool is a combined shears and spreader.
- a swing bolt construction is applied in all these tools to allow said mutually pivotable parts to rotate round a central pivot point, while the moving parts are simultaneously clamped to each other to hold them under a determined bias.
- the bias is important since it largely determines the effectiveness of the tool and the tool life of the components.
- a generally applied construction is that in which the moving parts rotate in a fork construction about a swing bolt, which is provided on an outer end with a screw thread onto which a nut is screwed. Pressing-together of the moving parts, and thereby holding the moving parts under bias, is effected in this manner. The fork construction and the pivotable parts are then clamped to each other.
- This known construction does however have a number of drawbacks.
- a quite large protruding part furthermore results on the side of the tool as a result of the height of the nut and the bolt head.
- the relatively large protruding part it is difficult to manoeuvre the tool, particularly when only little space is available in or close to the object.
- a further drawback is that, depending on the rotation direction of the moving parts (shear blades or spreader arms), a great radial force results on the swing bolt and/or the nut, whereby the nut can screw itself even tighter or even come loose, with the result that the bias increases or is lost. Losing the biasing force in this way can have a very adverse effect on the operation of the tool. A locking is therefore necessary to prevent the swing bolt construction losing the bias.
- the bolt head is therefore embodied such that it fits form-fittingly in a special recess, and can therefore no longer co-rotate.
- the nut of the swing bolt must then also be locked against undesired loosening. This is solved for instance by screwing a second nut on top of the first nut, or by the use of so-called locking nuts, locking plates or locking rings.
- a drawback of such a force-absorbing locking construction is that it obtains its effect by means of friction and can lose its effect as soon as a great axial force occurs in the pivot construction. Possible deformation results in play, with loss of bias as a result.
- This type of locking construction is further susceptible to vibrations, and locking rings are for instance less suitable in the case of hardened parts.
- Another drawback of these usual locking constructions is the fact that the friction necessary for good operation also uses a part of the torque applied to the nut, and a smaller part is therefore effectively left for the actual bias. It is further not possible to monitor objectively what bias remained when a nut is loosened using a special tool . The friction will always have a higher value prior to loosening than the actual applied torque.
- a tool for clamping together pivotable parts under bias relative to each other comprising: - a holder provided with a fork, wherein each of the outer ends of the fork is provided with an opening;
- the pivotable parts are hereby optionally clamped together directly without interposing of for instance the fork of the holder.
- the first advantage hereof is that the present swing bolt construction can be given a very compact form and can hereby also be lighter in weight. Both the swing bolt and the nut of the swing bolt construction remain inside the fork of the holder of the tool, so that there are practically no longer any protruding parts, and handling of the tool in limited spaces is facilitated.
- the widened part of the swing bolt and the nut lie during use directly against the sides of the pivotable parts directed toward the fork outer ends.
- no parts are arranged between the swing bolt and nut on the one hand and the pivotable parts on the other.
- the swing bolt construction can hereby be given an even more compact and lighter form than in the embodiment in which the swing bolt and nut lie in indirect manner against the pivotable parts.
- a non-cylindrical shape is arranged on the swing bolt, this shape corresponding with a recess in the fork of the holder so that the swing bolt itself cannot rotate.
- the nut must of course be able to rotate in order to transmit the bias to the pivotable parts.
- a widened portion is further arranged on both the swing bolt and on the nut, so that the fork of the holder and the pivotable parts are held together while taking some play into account .
- the widened part of the swing bolt and/or the nut comprises an at least partly conical part for the purpose of forming an oblique contact surface on the pivotable parts.
- the contact surfaces between swing bolt/nut on the one hand and the pivotable parts on the other have an inclining progression, and the effective distance between the two effective lines of force can become greater, thereby resulting, with the same force, in a greater holding torque on the pivotable parts.
- the tool comprises locking means for locking the swing bolt construction, wherein the locking means are arranged in the swing bolt construction.
- the locking means protrude less, or even not at all, outside the swing bolt and the nut themselves, as is for instance the case with the use of a second locking nut on the nut as described above. It is hereby possible to prevent the swing bolt construction having overly protruding parts at the position of the locking 1 ring, which would reduce the manageability of the tool in a limited space.
- the tool comprises locking means for locking the nut of the swing bolt construction, comprising:
- the locking can be ensured once the nut has been brought to the correct, predetermined bias.
- the toothings are embodied such that the nut can be locked relative to the swing bolt with relatively small angular displacement steps ( ⁇ ) .
- the displacement steps are preferably made as small as possible, such as an angular displacement step ( ⁇ ) between 1 ° and 5 " , and preferably between 1 " and 3 ' .
- the second locking ring is adapted to enable fastening to the nut in a predetermined number of rotation positions.
- the protruding part of the swing bolt is formed such that it fits in one or more corresponding internal recesses which are provided in the first locking ring for non-rotatable fastening of the first locking ring to the swing bolt.
- the nut is provided with a row of recesses into which external projections provided on the second locking ring can engage to enable non-rotatable fastening of the second locking ring to the nut in a number of positions.
- the second locking ring comprises at least one protrusion which protrudes from the nut in the assembled position, for instance when said projections are provided on the peripheral surface of the second locking ring, the recesses are provided in the peripheral edge of the nut and the projections protrude outside the nut in the assembled position, the second locking ring can be readily removed by hand.
- a further advantage is that, as long as the second locking ring is present, it is not possible for a hand-tool, such as for instance a polygonal socket wrench, to be used to loosen the nut. This requires a logical sequence wherein the locking ring is first removed before the nut can be loosened.
- a hand-tool such as for instance a polygonal socket wrench
- cover elements can be placed over the openings in the outer ends of the fork.
- the cover elements have the function, among others, of preventing parts of the swing bolt construction possibly shooting away as a result of breakage caused by extreme axial overloading, whereby the chance of injury to the operator and bystanders is greatly reduced.
- a further function of the cover elements is to protect the swing bolt construction from the outside world so that the chance of moisture or dirt possibly penetrating the swing bolt construction is reduced further.
- the outer ends of the swing bolt are provided with fastening means for fastening the cover elements during use to the respective outer ends of the swing bolt.
- the cover elements can hereby be locked on the tool .
- a cover element is for instance provided with an opening, in which can be arranged a fastening screw engaging on the swing bolt and the relevant cover element in the placed position.
- a swing bolt construction with integrated locking for instance in the tool described herein, wherein the swing bolt construction comprises:
- a second locking ring which can be mounted non- rotatably on the nut and placed between the nut and the first locking ring, wherein the second locking ring is provided with an internal toothing which can engage on the external toothing of the first locking ring.

- a hydraulic cylinder (not shown) with two pressure rods is arranged in known manner with which the shear blades can be operated.
- the outer ends 19,20 extend on either side of a first shear blade 5 and a second shear blade 6.
- Shear blades 5,6 are provided with a cutting edge 4 and can pivot relative to each other by means of a swing bolt construction as shown in the figures.
- Shear blades 5,6 comprise respective protrusions 7,8 in which openings 9,10 are arranged. Openings 9,10 are provided for mounting therein of the above stated pressure rods (not drawn) of the hydraulic cylinder. Shear blades 5,6 are further provided with openings 2, 11 respectively into which the above stated swing bolt construction 25 can be inserted. Shear blades 5,6 are pivotable relative to swing bolt construction 25 such that blades 5,6 can be opened and closed (direction P 1 , figure 1) by operating the hydraulic cylinders, which are each coupled to protrusions 7,8 by a pressure rod.
- Swing bolt construction 25 comprises a swing bolt 26 and an associated nut 32.
- Swing bolt 26 is constructed from an elongate body with a relatively small diameter, wherein a widened element 27, also referred to herein as bolt head, is provided on a first end 29.
- a widened element 27 also referred to herein as bolt head
- external screw thread 31 is provided on the opposite end 30 of swing bolt 26.
- the widened element 27 is further provided with a slightly protruding flange 28, while a star-shaped protruding part 49, also referred to as locking element 49, is provided on the opposite end surface of swing bolt 26.
- the outer diameter of widened part 27 of swing bolt 26 practically corresponds with the inner diameter of opening 21 in lower part 19 of the holder, so that the widened part 27 can be arranged fitting therein.
- the protruding flange 28 has a non-cylindrical form, for instance the polygonal form shown in figure 1, which corresponds with the form of the opening in outer end 19 of the fork of the holder, such that swing bolt 25 cannot rotate relative to this outer end 19.
- the outer diameter of nut 32 likewise corresponds to the inner diameter of opening 22, this opening 22 being provided in upper part 20 of the holder.
- the outer periphery of widened part 27 and the outer periphery of nut 32 will lie against the inner surface of respectively the lower part 19 and upper part 20 of the holder in the assembled situation (as shown in figure 4) .
- the elongate body part 26 has a smaller diameter comparable to the diameter of openings 11 and 2 in respective shear blades 5,6. This means that in the assembled situation the outer periphery of elongate part 26 lies against the inner side of said openings 11 and 2.
- flange 28 of the swing bolt comes to lie on a stop surface (not shown) provided along the edge of opening 11 in lower part 19 of the holder.
- transition part 37 takes a substantially straight form at the position of the transition between widened part 27 and the relatively narrow elongate part 26 of swing bolt 25.
- transition part 39 has a conical shape. The shape of transition part 39 is here adapted to the transition part extending along opening 11 in shear blade 6.
- the nut 32 can be provided with a straight transition part 38, as shown in figure 4, or with a conical transition part 41 as shown in figure 5.
- the shape of respective transition parts 38, 41 is adapted to the straight or conically extending edge part of opening 11 of the other shear blade 5.
- the transition parts provide conically tapering contact surfaces between the swing bolt and nut on the one hand and shear blades 5,6 on the other.
- the bias can now be transmitted at an angle to pivotable parts 5,6 via the conical contact surfaces of bolt head 27 and nut 32, which makes it possible to obtain a greater bias.
- swing bolt 26 is provided on outer end 30 with a for instance star-shaped locking element 49, embodied with six protrusions 61 (figure 3A) .
- Nut 32 is likewise provided with a number of projections 34, between which recesses are defined.
- An inner ring 43 provided with an internal fitting form 57 and an external toothing 44 is arranged close-fittingly on star-shaped locking element 49. Then arranged around inner ring 43 is an outer ring 40, the internal toothing 58 of which corresponds with the external toothing 44 of inner ring 43. Outer ring 40 is provided with external projections 42 which fit into the above mentioned recesses on the top side of nut 32.
- the locking construction is embodied such that there is a predetermined minimum play between locking element 49 on swing bolt 25, inner locking ring 43, outer locking ring 40 and the mounting in nut 32, i.e. projections 34 and the recesses corresponding therewith on the top side of nut 32.
- guards 50,51 are then finally arranged on either side of the holder.
- Guards 50,51 are provided for this purpose with longitudinal edges 52 which can slide laterally along the bottom edge of respectively the lower part 19 and upper part 20 of the fork.
- Figure 1 shows the situation in which guards 50,51 have not yet been mounted.
- the guards are displaced in the direction of arrow P 3 in the position shown in figure 1, they can slide readily over the outer ends of the lower and the upper part 19,20. In order to ensure that the guards always remain in place during use, they can also be locked.
- Guards 50,51 are provided for this purpose with an opening 53 where a locking screw 46 can be arranged.
- Locking screws 46 can be screwed fixedly into corresponding openings 47 provided in swing bolt head 27 and in the outer end of the swing bolt close to locking element 49. It is however also possible to envisage other ways of locking the guards on the holder.
- inner ring 43 is formed integrally with the ' outer end of the swing bolt instead of the locking element 49.
- inner ring 43 is formed integrally with the ' outer end of the swing bolt instead of the locking element 49.
- inner ring 43 is formed integrally with the ' outer end of the swing bolt instead of the locking element 49.
- the manner of locking the nut 32 corresponds with that described above.
- the above described embodiment with separate inner ring 43 has the advantage that it is quite easy to produce.
- the swing bolt construction according to the invention is applied in the manner to be described hereinbelow.
- the first locking ring can be placed on the protruding part of the swing bolt.
- the second locking ring can then be arranged, this such that the internal toothing of the second locking ring engages somewhere on the external toothing of the first locking ring, while the protruding parts of the second locking ring fit simultaneously into the recesses of the nut.
- the position of the nut must of course not be influenced here. In earlier locking constructions the number of teeth and points of engagement on the nut are chosen at random, whereby it is possible that the second locking ring will not always fit.
- the locking ring can be removed in simple manner by allowing the external protrusions of the second locking ring to protrude slightly outside the nut.
- the second locking ring must as a result be first removed before a socket wrench can be placed. This requires a logical and safe method.
