Claims

[Scope of utility model registration request]

(1) A chuck member located on the front end side of a cylindrical workpiece and having a base and a plurality of claws arranged radially around the axis of the workpiece on the base surface of the base; and the rear side of the workpiece. an axial positioning member for stopping rearward movement of the workpiece in the axial direction; Each of the claws is rotatably provided with a rotation axis extending in a direction perpendicular to a radial direction centered on the axis of the workpiece and parallel to the base surface. each of the claws has a workpiece front end support part that can come into contact with the front end of the workpiece, and a workpiece pressing part that can come into contact with the inner circumferential surface of the workpiece, and each of the claws has a workpiece front end support part that can come into contact with the front end of the workpiece, and a workpiece pressing part that can come into contact with the inner circumferential surface of the workpiece, and the chuck member and the axial positioning member As the two move relatively closer to each other, a load from the axial positioning member is applied to the workpiece front end support part of the claw through the workpiece, whereby the claw rotates and the workpiece pressing part moves toward the front end of the workpiece. A workpiece positioning device that fixes the workpiece by pressing the inner peripheral surface of the workpiece radially outward.

(2) a load applied to the workpiece front end support portion;
The workpiece positioning device according to claim 1, which is provided with a spring that returns the claw to its pre-rotation state when the claw is released.

(3) A utility model comprising a pawl holder that contacts one end of the pawl and presses the one end of the pawl in the forward direction of the workpiece, and is always biased in the forward direction of the workpiece by a spring. A workpiece positioning device according to claim 1 or 2.

(4) The workpiece positioning device according to any one of claims 1 to 3, wherein the chuck member is rotatable around the axis of the workpiece.
