GRIPPER DEVICE FOR MOUNTING RUBBER ELASTIC RINGS AND FINGER FOR A GRIPPER DEVICE OF THIS TYPE

摘要

The invention relates to a gripper device (10) for mounting rubber elastic rings (50) on the inner wall (62) of a workpiece opening and/or on the exterior of a workpiece. Said device comprises a basic housing (12), forming jaws (14) that can be displaced in relation to the basic housing (12) and bearing jaws (16). The individual forming jaws (14) and the individual bearing jaws (16) are respectively coupled to one another in such a way that the forming jaws can be displaced independently of the bearing jaws and the bearing jaws can be displaced independently of the forming jaws in a radial direction towards or away from one another. The device also comprises an axially displaceable plate element (18), on which the forming jaws or the bearing jaws are located. To displace the plate element together with the jaws that are located on said element in an axial direction, the element is provided with a piston (20) which engages in a piston cylinder (22) in the basic housing. The invention is characterised in that the displacement of the jaws that are located on the plate element (18) is mechanically coupled by means of a common actuator (24) and that said actuator (24) is driven by an actuator piston (25) that is located in the piston (20).
