Claims

[Scope of utility model registration request]

It has two replaceable clamp claws 7, 8, and in order to clamp the workpiece W, one of these clamp claws 7 can be rotated about the clamp axis by a clamp mechanism 9, and these clamp claws 7, 8 In order to machine a plurality of machining axes of the workpiece W, an auxiliary plunger 13 and an auxiliary plunger 13 are attached to the indexing surface of the square piece 11 of the indexing mechanism 10 that drives the other clamp claw 8 together with the clamped workpiece W. In the indexing chuck 1 which performs indexing of square pieces in stages by making contact with the main plunger 12 alternately, the chuck main body 6
An arm fulcrum portion 18 of the clamp arm 17 of the clamp mechanism 9 is provided to swingably support the clamp arm 17 at a suitable intermediate position.
For a machine tool, the tip 19 of one arm is fitted into the clamp plunger 16 of the clamp mechanism 9, and the rear end 20 of the other arm is fitted into the clamp piston 23 of the clamp mechanism 9. Indexing check.
