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.
