摘要： PROBLEM TO BE SOLVED: To provide a compact chuck device which can solve a problem that a conventional chuck device for gripping a workpiece in a friction welding machine is designed to be necessarily long in the axial direction because components of the chuck device such as hydraulic cylinders for driving, plungers and claws are arranged in parallel with the axial direction so that the length of the workpiece in the axial direction is limited.
SOLUTION: The chuck device for the friction welding machine is equipped with claws 2 which grip a workpiece 4 by moving inward in the radial direction, hydraulic cylinders 5 linking with the claws and spring steel 9 fixed to the claws. The spring steel accumulates contractile force inward in the radial direction by the action of the hydraulic cylinders 5 when the workpiece is released and moves the claws inward in the radial direction with the contractile force when the workpiece is gripped.
