ABSTRACT:
A coupling construction and a clamp therefor are disclosed which are operative with improved effectiveness in a workholding system for securing a workpiece at a work station. The coupling comprises a receiver and a carrier, and at least one of the clamps for securing the receiver and the carrier in a coupled position with high clamping pressures. The clamp comprises a clamp body, and a clamping element, a movable member, a spring assembly and an actuating assembly on the clamp body. The actuating assembly preferably includes a toggle member having oppositely facing knuckle elements thereon which are rotatably received in sockets for mounting the toggle member so that it is pivotable to actuate the spring assembly for biasing the movable member toward the clamping element. When the clamp is assembled in the coupling, and the receiver and the carrier are received in a coupled position between the clamping element and the movable member, the toggle member is pivotable to actuate the spring assembly for applying clamping pressures to the receiver and the carrier to secure them in the coupled position.
