おけるワーク把持機構。 In a friction welding machine for friction welding a pair of rod-shaped workpieces, this is a workpiece gripping mechanism for removably gripping one of the rod-shaped workpieces, and has a tapered pressing surface that expands in diameter toward the tip. A holder having a mounting hole provided at the tip, a tapered pressure-receiving surface corresponding to the pressing surface on the outer periphery, and an insertion hole that is concentric with the mounting hole and open on the tip side for inserting the workpiece. The collet is fitted into the mounting hole so as to be movable in the axial direction and is capable of contracting in diameter in response to pressure on the pressure receiving surface, and a driving means connected to the collet to drive the collet in the axial direction. In a friction welding machine, the means is connected to allow the workpiece to move inward in the axial direction until it comes into pressure contact with the inner surface of the insertion hole in response to a pressing force applied to the collet from the outside in the axial direction. Workpiece gripping mechanism.
