Claims

[Scope of Claim for Utility Model Registration] A clamping device in which a clamp member for restraining the outer periphery of a collet is slidable along a collet axis and is biased in one direction to clamp a workpiece in a collet chuck portion, The shaft core is provided with an insertion hole for supplying a workpiece, which is inserted toward the chuck portion, and a pushing cylinder unit is provided on the workpiece supply side of the insertion hole, with the tip of the pushing rod facing on the extension line of the entrance of the insertion hole. A receiving member for transferring the workpiece is provided at the entrance of the insertion hole, and a transfer cylinder unit for driving this receiving member moves the receiving member at the workpiece receiving position to the entrance of the insertion hole in the first stroke, and in the second stroke. A clamp device characterized in that the clamp member is configured to slide toward the release side.
