Abstract

PURPOSE: To enable to maintain the clamped state even after the clamping power is removed and to leave the clamping pressure unreleased even at the power source failure by a method wherein a rectilinear member is pressed in by a power means between the rotary member, the tip jaw of which can contact with the surface of an object to be clamped, and a fixed member in order to produce the clamping force therebetween.
CONSTITUTION: A clamping arm 5 with its upper plane formed in circular arc shape is fitted to the bearing 3 of a lower member 1 through a shaft 4. Under the condition that the tip of the clamping arm 5 is contacting with the upper surface of the object to be clamped such as mold or the like, a slider 6 is applied with an external force P such as a hydraulic pressure or the like parallel to the lower surface of the upper member 2. As a result, the rectilinear slider 6 is forcibly pressed in between the gap formed by the lower surface of the member 2 and the circular arc shape surface of the arm 5, producing the large vertical component of force F, inversely proportional to an angle θ between the upper and lower surfaces, on the lower surface of the member 2 and the contact line of the upper surface of the arm 5 with the slider 6. As, once pressed in, the pressed-in state of the slider 6 is held continuously even after the external force P is released, so the clamping pressure is left unreleased even at the power source failure.
