Abstract
A workpiece gripping mechanism for an industrial robot is described. A support member having a first jaw member mounted on it for pivotal movement about a first axis is provided. The support assembly and the first jaw assembly define a first rotary fluid-actuated motor operable to pivotally displace a jaw member in the first jaw assembly relative to the support member about the first axis. A second jaw assembly is also mounted on the support member for pivotal movement about the first axis. The support member and the second jaw assembly define a second rotary fluid-actuated motor operable to pivotally displace a jaw member in the second jaw assembly relative to the support member about the first axis whereby the first and second fluid-actuated motors may be operated independently to pivotally displace the jaw members relative to each other for gripping and releasing a workpiece and to displace the jaw members relative to the support member.
