Hereinafter, the operation of the work support grinding apparatus of the present invention having the above-described structure will be described with reference to FIG. 1 to FIG.

First, the worker mounts the work support W to the support fixing member 120. Both ends of the work rotation shaft 4 of the work support W are mounted and fixed to the support fixing member 120 and the work rotation shaft 4 is connected to the work rotation motor 128.

The worker adjusts the angle of the grindstone member 166 according to the angle of the grind groove 2 of the work support W in a state where the work support W is mounted on the support fixing member 120. [

The angle of the grindstone member 166 may be adjusted by using the first tilting means 150 and the second tilting means 180 so that the grindstone member 166 ) To adjust the grinding angle.

The first tilting means 150 may adjust the rotation angle of the grinding stone member 166 with respect to the vertical axis of the grinding stone member 166 and the second tilting means 180 may adjust the angle of rotation of the grinding stone member 166, The rotation angle of the grindstone member 166 can be adjusted on the basis of the horizontal axis of the grindstones 166.

Therefore, since the angle of the grinding stone member 166 can be adjusted by a simple operation according to the angles of the various grinding grooves 2 formed in the work support W, the working time of the grinding process is shortened and the grinding efficiency There is an advantage to be improved.

The work support W is rotated in one direction by the work rotating motor 128 and the work transfer plate 102 provided at the lower portion of the support holding member 120 is moved in the right direction to grind the grindstone member 166 To move the work support W toward the work support W side.

When the angle of the grindstone member 166 is adjusted, the workpiece transfer plate 102 is moved to the right to grind the workpiece support.

The worker repeatedly grinds the work support W by performing the grinding work by moving the work support W left and right according to the degree of wear of the work support W. [

When the grindstone member 166 is grinding for a long time, the outer diameter of the grindstone member 166 is worn, so that dressing is performed to dress the outer diameter of the grindstone member 166.

A pair of dressing members 212 are provided above the grindstone member 166. The dressing member 212 is formed in a disk shape, and is moved in the forward, backward, left, and right directions. The dressing member 212 closely contacts the slope portion 172 and the protrusion 174 forming the outer diameter of the grindstone grindstone 166 and dresses the grindstone grindstone 166.

In the dressing process of the dressing member 212, the dressing member 212 provided on the left side of the grinding stone member 166 is moved from the left to the right to primarily perform the dressing, and the first dressing process is completed The dressing member 212 provided on the right side of the grindstone 166 is moved from the right side to the left side to perform the dressing.

That is, the dressing members 212 are formed as a pair and repeatedly perform the dressing of the grindstone 166. In addition, the connecting portion between the inclined portion 172 and the protruding portion 174 is formed in an orthogonal shape so that precise dressing of the grindstone 166 can not be performed by only primary dressing.

Thus, the dressing process is performed on the orthogonal surfaces of the inclined portion 172 and the protruded portion located on the right side by the primary dressing, and the dressing is performed on the orthogonal surfaces of the inclined portion 172 and the left- Dressing is performed.

Since the dressing process of the grinding groove having a complicated structure can be performed by the dressing means 210, precise dressing processing can be performed on the grinding stone member 166.

The scope of the present invention is not limited to the embodiments described above, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.
