Abstract (en)
[origin: EP0066640A1] Advancing and retracting mechanism for clamping means comprising a pair of split nuts (3, 3 min ) resiliently retained in place inside a hollow cylindrical body (1) by spring means, which mechanism can either slidably hold a screw spindle (2) to rapidly push it to working position or retract it to dismount the workpiece when the threads (31, 31 min ) of split nuts (3, 3 min ) are not in mesh with the screw spindle (2) or offer a snug. Complete engagement between the split nuts (3, 3 min ) and screw spindle (2) in which the load is equally distributed, thereby largely reducing the wear thereof, and allowing the device to be fabricated in relatively small size.
