ABSTRACT:
A clamping device for the play-free fixing of a bar has clamping jaws radly slidably mounted in the housing of the device, into an outer release position and an inner clamping position. A double-acting servo-piston is disposed about the bar and has connected to it wedge elements which extend axially between the housing and the respective jaws and which have inclined faces engaging correspondingly inclined faces of the jaws, so that axial movement of the servo-piston causes the jaws to move inward towards or outward from the clamping position. A releasable locking device may additionally be provided for locking one or more of the wedge elements and the piston to the wall of the housing when the piston is in its position corresponding to the clamping position of the jaws.
