ABSTRACT:
A gripper for holding a manufactured part in a X-ray inspection system. The gripper includes a stationary jaw, a slidable jaw, a gripper base, a wear plate, a centering bushing an end plate, and a cam actuated spring mechanism for opening and closing the jaws. Both jaws are removable and adjustable in a keyway. Set screws are used to hold the jaws in place for a predetermined separation and allows a part to be positioned off center. The removable aspect allows for various jaw configurations. The centering bushing includes a cam shaped opening for accepting an end of an pneumatic activated ball plunger of a numerically controlled part manipulator. The centering bushing aligns the gripper to the longitudinal axis of the part manipulator.
