Abstract

A robot gripper jaw assembly includes a support plate having front and rear faces. Jaw mounts extend from the front face and cooperating jaws are pivotally mounted to the jaw mounts for gripping work. The support plate has an opening therein generally centrally disposed relative to the jaw mounts and a cylinder and piston assembly is secured to the support plate rear face in alignment with the opening. The piston of the cylinder and piston assembly extends through the opening and is engagable with the jaws so that forward and rearward movement of the piston causes cooperative pivoting of the jaws for closing and opening the jaws for gripping and releasing work. The support plate and the cylinder and piston assembly have a central rotational axis and the robot includes an assembly for simultaneously rotating the support plate and the cylinder and piston assembly on the rotational axis.
