    摘要: A double hand for an industrial robot comprises a hand body, two sets of work clamping units and two sets of actuators to drive the work clamping units, respectively, for opening and closing motions. The hand body has a rear end attachable to the free end of the robot wrist of an industrial robot, a front end and opposite sides extending between the front end and the rear end. Each work clamping unit has a pair of gripping fingers and the pairs of gripping fingers of the two sets of work gripping units are supported pivotally at the roots thereof on the opposite sides of the hand body for turning motion. The paired gripping fingers are turned about the respective roots thereof in opposite directions by the associated actuator.
