Claims

[Claims for Utility Model Registration] (1) An indexing shaft 11 that supports a table 12 on which a workpiece is placed so as to be rotatably and axially movable with respect to the base frame 10, and A driven member 18 provided on the table 1 is driven by a rotary drive machine 24 and is engaged with the driven member 18.
a drive member 26 for indexing at the required angle of 2;
27, and coupling rings 16 and 17 that are provided between the table 12 and the base frame 10 and fix and release the fixation of the table 12 in a non-rotatable manner. 26, 27
An indexing device comprising moving members 30, 31, and 34 that release and fix the coupling rings 16 and 17 by moving the index shaft 11 based on the operation of the indexing device. (2) The moving member is provided on the driving member 26, and the moving member is provided on the driving member 26.
a planar cam 31 that rotates integrally with the planar cam 31; and a contact member 3 that is swingably supported on the base frame 10 and that comes into contact with the cam surface of the planar cam 31 at one end.
0, and the other end is comprised of a seesaw arm 34 that can come into contact with the lower part of the indexing shaft 11.
Indexing device as described in Section. (3) The cam surface of the planar cam 31 has the lowest region d to a, the region a to b that slopes upward from the lowest region, and the region b that extends horizontally from the highest region to the highest slope. c, and areas c to d that have a downward slope from this highest horizontal area, and this downward slope area is formed so as to be continuous with the lowest area. Output device.
