The quick change attachment for clamping chucks on a machine spindle has a locking bush actuated by an axially shiftable locking piston for actuating the chuck clamping. An adjusting rod is adjustable from the clamping cylinder is provided for actuating the clamping jaws of the chuck. Axially secured at the end of the adjusting rod to connect the clamping piston rod with the adjusting rod are couplings. These execute plier-like gripping and expanding movements by tipping edge and are actuated from a control bush overlapping them together with the locking bars for the chuck clamping driven by the locking bush. |
