ABSTRACT:
An abutment with a damping device, more particularly for automatic machining or conveying equipment, comprising an abutment member which is able to be moved from a first abutment position as far as second end abutment position while subjected to a damping action. A fluid power operated setting member can move the damping device (which is connected with the abutment member) perpendicularly to the direction of the abutment action and is able then to move the abutment out of an abutment plane and back into it. The damping device has in this case at least one damping piston adapted to run in at least one damping cylinder, there being a choke device which damps the piston movement and provides resistance for the ingoing or outgoing air during piston movement. Both the setting member and also the damping device operate by a fluid power effect, individual adaptation of the damping properties being possible for workpieces with different masses and/or different speeds of movement.
