ABSTRACT:
An industrial robot is described having a movable arm, a wrist pivotally mounted for motion about an axis at the free end of the arm, and a cylindrical shaft perpendicular to said axis and rotatably mounted on the wrist. To enable it to be used for holding components subjected to forces, as during grinding operations, the robot is provided with a pair of jaws that can be clamped on the shaft and are able to prevent both the shaft from rotating and the wrist from pivoting. Movement of the jaws is controlled by shoes which are slidably mounted on a pair of circularly curved parallel rails having a common center coinciding with the pivotal axis of the wrist.
