ABSTRACT:
A gripping mechanism having jaws for picking up and releasing parts is carried on an outwardly and inwardly swinging parallel linkage which, in turn, is mounted on an upwardly and downwardly swinging parallel linkage. A spring-loaded snubber takes out play in the linkages to insure precise positioning of the gripping mechanism at the ends of its outward and inward strokes. The jaws of the gripping mechanism are open and closed by a compactly mounted fluid-operated actuator, are connected to one another by an equalizing link which effects automatic self-centering of the jaws, are adapted to rotate the part as the part is transferred, and are adapted to be opened and closed with either a swinging motion or a straight line motion.
