ABSTRACT:
A clamp has a clamping arm pivotally mounted to a base frame for swinging between clamping and unclamping positions. An actuator, such as a pneumatic cylinder, provides bidirectional forces for swinging the arm. The arm is driven by the actuator by way of an articulated linkage system including at least one spring link and one rigid link. The spring link preferably has a C-shape.
