Abstract
An improved shiftable clamp () adapted for connection to a fixture () is provided, wherein the clamp () is selectively operable to engage and hold a workpiece () to the fixture (). The clamp () includes a tubular body () and a piston () telescopically received within the body (). Movement of the piston () is guided and controlled by way of a cam assembly () including a cam track () formed in the piston () and an associated cam track follower ball () mounted on the body (). A spring unit () is also provided on the body () and includes a spring () serving to self-center and bias the ball () into the track (). This insures that the ball () smoothly rotates during movement of piston () and reduces wear and premature clamp failure.
