Title: Device for clamping rotating axis of machine tool
Inventor: PARK JONG YOUNG
IPC: B23Q16/08
Filed: 2009-12-07
Abstract: PURPOSE: A device for clamping a rotary shaft of a machine tool is provided to prevent the abrasion of a piston by rapidly returning a clamp pad and piston with unclamped state using an elastic member. CONSTITUTION: A device for clamping a rotary shaft of a machine tool comprises a clamp pad(9), an upper piston(7), a piston rod(8), a hydraulic line(5), and an elastic member(11). The clamp pad clamps a ring gear on the top of a ring gear(4). If the upper piston is upward moved, the upper piston clamps the ring gear along with the clamp pad by pressing the lower side of the ring gear.
