Claims

[Scope of utility model registration request]

A reference surface perpendicular to the axis of the chuck is used as a mounting surface for one end surface of the circular workpiece, and a master claw, which is locked to the chuck so as to be movable in the radial direction, is placed in a direction parallel to the axis of the chuck. A pin is implanted, a child claw capable of radially clamping the workpiece is floatingly supported by the parent claw via a spring so as to be able to swing around the pin, and a position where the child claw is crimped by the pin is set. The position is distant from the reference plane from the pressure contact position between the child claw and the side surface of the workpiece, and the gripping force of the workpiece in the radial direction of the child claw is generated by the clamping force based on the movement of the master claw in the radial direction. and a pressing force is generated in the direction of the chuck axis,
A ring-shaped workpiece gripping device, characterized in that the workpiece can be held under pressure on the reference surface.
