Abstract
A power actuated gripper for engaging and holding a workpiece wherein a cam surface is pivotally linked to a reciprocating actuator for actuating at least one of a first and second jaws between a clamped position, wherein the first and second jaws engage and hold the workpiece, and an unclamped position, wherein the first and second jaws disengage and release the workpiece. The reciprocating linear actuator provides a fluid motor with a piston and piston rod for providing linear reciprocal movement. The piston rod is connected to a coupling member which is pivotally connected to a pair of linkage members for each of the first and second jaws. A pair of lever arms are pivotally connected to the linkage members and are integral with a shaft link. The cam surface is formed on the shaft link and actuates a cam follower, biased toward the cam surface, connected to the first and second jaws. The first jaw moves linearly between the clamped and unclamped positions, and the second jaw provides a linkage portion and a swing arm wherein the linkage portion has a linear moving portion linked to the swing arm. The swing arm is rotatably connected to the pivot pin for simultaneous rotary moveme…
