Claims

[Claims for Utility Model Registration] (1) A workpiece positioning and moving device that positions and moves a workpiece having a circular outer circumferential surface concentrically with a predetermined center line, the workpiece being moved by the moving device and a movable member that is stopped at a predetermined workpiece attachment/detachment position; and three or more clamps disposed on the movable member at equal angular intervals around the one center line and movable toward and away from the one center line. a pawl; a rotary member supported by the movable member so as to be rotatable about the one center line; a rotary member provided on the rotary member so as to be engageable with each of the three or more clamp pawls; is rotated in one direction around the one center line, thereby moving the clamp pawl in a direction approaching the one center line by a wedge action, and pressing it against the circular outer circumferential surface of the workpiece; , a biasing means disposed astride the rotary member and the movable member and biasing the rotary member so as to always rotate in the one direction; and a biasing means disposed at the workpiece attachment/detachment position. , an unclamping means that engages with the rotating member and rotates the rotating member in a direction opposite to the one direction. (2) The rotating member includes a manual that manually rotates the rotating member in a direction opposite to the one direction and is engaged with the moving member to hold the rotating member in an unclamped position. The workpiece positioning and moving device according to claim (1), further comprising an unclamping device.
