1. A clamp apparatus comprising:
- a clamp includinga clamp block presenting an integral and generally U-shaped configuration having spreadable, opposed arms interconnected by a base to define a clamping jaw shiftable between a retracted position and an extended, clamping position, anda clamp operator presenting a generally wedge-shaped body received in a complimentary configured opening defined in said block between the opposed arms; and
a power cylinder including a selectively shiftable piston rod extending therefrom and coupled with said operator in order to shift said operator and thereby shift said jaw between said positions.

Abstract
A preferred clamping apparatus includes an hydraulic pull cylinder having a piston rod connected to the shaft of a wedge-shaped clamp operator received in a complementally shaped opening defined in a clamp block having a shiftable jaw. In operation, retraction of the piston rod pulls the operator toward the base of the block in order to shift the jaw to a clamping position to hold a workpiece. In preferred forms, the clamping apparatus is included as part of a fixture and operable to clamp a workpiece to the fixture.

10. A workpiece holding assembly comprising:
-
a fixture configured to receive a workpiece; and a clamp apparatus including a clamp block supported by said fixture and presenting a generally U-shaped configuration with opposed arms integrally interconnected by a base to form a clamping jaw shiftable between a retracted position and an extended, clamping position, said jaw being located for clamping a workpiece received by said fixture when in said clamping position, a clamp operator presenting a generally wedge-shaped configuration received in a complimentary configured opening defined in said block, said jaw being shiftable between said positions upon shifting of said operator in said opening, and a power cylinder supported by said fixture including a selectively shiftable piston rod extending therefrom and coupled with said operator in order to shift said operator and thereby shift said jaw between said positions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
