ABSTRACT:
A centering and holding fixture includes a base, a piston disposed within a piston chamber at least partially located within the base, and a radially flexible ring connected to the piston by force transmission apparatus operable to contract and expand the radially flexible ring by upward and downward motions respectively of the piston. The flexible ring may be slotted and may include alternating inwardly and outwardly extending radial slots extending axially through the flexible ring and extending radially inwardly and radially outwardly from radially outer and inner surfaces of the flexible ring respectively to axial stress relief holes extending axially through the flexible ring. The apparatus may further be operable to contract the radially flexible ring when the piston chamber is pressurized and to expand it when the piston chamber is depressurized. Spring loaded clamps mounted to the base may be used to secure a workpiece to the holding fixture.
