Claims

[Claims for Utility Model Registration] A spindle center 2 that supports a workpiece W; a rotary drive body D that is rotationally driven around the rotational axis of the spindle center 2; and a chuck assembly A that is driven by the rotation drive body D. The chuck assembly A includes a base drive flange 6 supported by the rotary drive body D so as to be movably adjustable in the radial direction;
An inner boss 11 is rotatably supported by the base drive flange 6 and has a center hole ₁₁₁ loosely inserted into the spindle center 2 so as to be movable in the radial direction; a plurality of clamp cams 13 supported by the base drive flange 6 so as to be swingable in the radial direction; the clamp cams 13 are supported by the base drive flange 6 and engaged with the cam surface 15 of the clamp cam 13 to control the rotation of the base drive flange 6; a plurality of cam followers 16 that transmit the signal to the clamp cams 13 and swing the plurality of clamp cams 13 inward in the radial direction; and clamp pins 18 that are respectively provided on the plurality of clamp cams 13 and can clamp the outer circumferential surface of the workpiece W. A workpiece clamping device characterized by: The workpiece clamping device according to claim 1, wherein the plurality of clamp cams 13 are provided with a locking mechanism L that locks the clamp pin 18 in a position-adjustable manner.
