Abstract
A removal structure for a central shaft of a sanding belt is fixed on a grinding machine, and the grinding machine contains: a driver, a driving shaft mounted on a top of the driver, a fitting sleeve extending outwardly from a central position of the driving shaft, a conical groove defined in the fitting sleeve, and at least one L-shaped notch formed on a peripheral wall of the fitting sleeve. A connection column is fitted with the driving shaft and includes a central shaft formed in a cone shape so as to correspond to the conical groove of the fitting sleeve, and the central shaft has at least one locking post corresponding to the at least one L-shaped notch.
Description
- The present invention relates to a removal structure for a central shaft of a sanding belt which fixes a connection column with a grinding machine and removes the connection column from the grinding machine easily by using at least one L-shaped notch of the grinding machine and at least one locking post of the central shaft.
- A conventional grinding machine contains a central shaft of a sanding belt connected with its driving shaft by using at least one screw bolt, and the central shaft is removed from the driving shaft of the grinding machine by way of hand tools.
- For example, as removing the central shaft of the sanding belt, a first hand tool is used to fix a connection column, and a second hand tool is applied to screw or unscrew the at least one screw bolt, thus replacing the connection column troublesomely.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The primary objective of the present invention is to provide a removal structure for a central shaft of a sanding belt which fixes a connection column with a grinding machine and removes the connection column from the grinding machine easily by using at least one L-shaped notch of the grinding machine and at least one locking post of the central shaft.
- To obtain above-mentioned objective, a removal structure for a central shaft of a sanding belt is fixed on a grinding machine, and the grinding machine contains: a driver, a driving shaft mounted on a top of the driver, a fitting sleeve extending outwardly from a central position of the driving shaft, a conical groove defined in the fitting sleeve, and at least one L-shaped notch formed on a peripheral wall of the fitting sleeve.
- A connection column is fitted with the driving shaft and includes a central shaft formed in a cone shape so as to correspond to the conical groove of the fitting sleeve, and the central shaft has at least one locking post corresponding to the at least one L-shaped notch.
- Preferably, the at least one L-shaped notch is formed on the peripheral wall of the fitting sleeve in an array arrangement.
- Preferably, a number of the at least one locking post is equal to that of the at least one L-shaped notch.
- Preferably, a diameter of a lower section of each of the at least one L-shaped notch is less than each of the at least one locking post.

FIG. 5 is another cross sectional view showing the operation of the removal structure for the central shaft of the sanding belt according to the preferred embodiment of the present invention. - With reference to
FIGS. 1 to 3 , a removal structure for a central shaft of a sanding belt according to a preferred embodiment of the present invention is fixed on agrinding machine 10, and thegrinding machine 10 comprises: adriver 11, adriving shaft 12 mounted on a top of thedriver 11, afitting sleeve 13 extending outwardly from a central position of thedriving shaft 12, aconical groove 15 defined in thefitting sleeve 13, and at least one L-shaped notch 14 formed on a peripheral wall of thefitting sleeve 13 in an array arrangement. Aconnection column 20 is fitted with thedriving shaft 12 and includes acentral shaft 21 formed in a cone shape so as to correspond to theconical groove 15 of thefitting sleeve 13, wherein thecentral shaft 21 has at least onelocking post 22, a number of which is equal to that of the at least one L-shaped notch 14. - Referring to
FIGS. 3 to 5 , the at least onelocking post 22 of thecentral shaft 21 is inserted into theconical groove 15 of thefitting sleeve 13, and theconnection column 20 is rotated so that the at least onelocking post 22 retains in the at least one L-shaped notch 14 respectively, wherein a diameter of a lower section of each of the at least one L-shaped notch 14 is less than each of the at least onelocking post 22, thus limiting thecentral shaft 21 in thefitting sleeve 13 and removing theconnection column 20 easily. - While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
