Wechseleinrichtung fuer die Greiferbacken eines Industrieroboters

In order to handle tools or workpieces, industrial robots are provided with a gripper device having two gripper jaws moving synchronously in opposite directions. The new changing device is intended to permit a simple and fast automatic change of gripper jaws. The changing device has a fixture for the gripper jaw which is friction-locked in the fixture. The gripper jaw is mounted in the fixture transverse to the direction of motion of a gripper jaw holder, having a positive-locking part insertable in an opening of the gripper jaw. The gripper jaw holder is moved by the industrial robot transverse to the gripper jaw through the fixture, whereby the positive-locking part engages in the opening of the gripper jaw, thus connecting it to the gripper jaw holder. The changing device is suitable for use with industrial robots.
