Abstract
PURPOSE:To improve substantially accuracy in indexing by securing fixedly blocks to both side positions of a claw guide groove 1a of a chuck body 1 for a machine tool so that support claws are pressed against the block by a jib for reinforcement after a workpiece is clamped. CONSTITUTION:Blocks 4, 5 parallel to each other are secured fixedly to both sides of clamp claw 3 in both side positions of a claw guide groove 1a of a chuck body 1. A liner 6 is secured fixedly to the side surface of the block 4 of clamp claw 3 side and bears against the side surface of clamp claw 3. Further a jib 7 is interposed between the block 5 and the clamp claw 3. Before a workpiece W is clamped by the chuck, the jib 7 is drawn out to ward the outer periphery by an adjusting bolt 9 to provide a gap between the jib 7 and the clamp claw 3 so that the clamp claws 3 can be freely opened and closed and the workpiece W is clamped concentrically. The jib 7 is pushed in the direction of center by the adjusting bolt and the clamp claws 3 are pressed against the liner 6 by the jib 7 to be pinched and clocked between the blocks 4, 5.
