ABSTRACT:
A clamping device includes three clamping jaws guided at an angle in a hong for engaging an axially displaceable load-bearing rod. Reliable clamping is obtained without alteration of the setting position reached. This is achieved by providing a servo-piston in the housing, which piston is displaceable in both directions by servo-force and is directly connected to the clamping jaws. The frictional force between the rod and the bearing faces of the clamping jaws as well as between the guide faces of the clamping jaws and their associated guide tracks in the housing, as well as the angle of inclination of the guide tracks are such that, in operation, self-locking occurs. The clamping action of the clamping jaws may be released only by moving the servo piston.
