Abstract
PURPOSE: To accurately maintain clamping force by receiving and tightly holding a clamp arm in flexibly deformed clamping conditin with use of a mechanical lock tool.
CONSTITUTION: Actuation of a ram 13 in a hydraulic cylinder thrusts a clamp arm 6 to the clamp side. Then, a mechanical lock tool 23 is rocked downward, its contact cam face 25 is brought into contact with a receiving face 26 to be in clamp- locking posture, the clamp arm 6 is received in flexibly deformed clamping condition by the lock tool 23 to mechanically tightly hold it. And the instant that the contact surface 25 of the lock tool 23 and the receiving face 26 becomes in noncontact condition by shocks and vibrations due to a tool 3, etc., the lock tool 23 is locked downward by tensile force of a change-over spring 27, the lock tool 23 is gradually bitten by the cam face of the contact surface 25, the contact surface 25 and the receiving face 26 come into contact with each other, so that the clamping condition is held and the clamping force is maintained.
