Abstract: A clamping device for objects, has a housing, at least two clamping jaws which is radially displaceably guided relative to a longitudinal central axis, actuating elements associated with the clamping jaws for actuating the latter, clamping pistons displaceable in a cylinder chamber and acted for clamping of the clamping jaws by a pressure medium under pressure at least in one working direction, the actuating element being in operative communication with the clamping piston at least in a working position, at least one central adjusting device displaceably arranged in the housing and acting on the actuating elements, abutment means including an abutment for each of the actuating element against which each of the actuating elements can abut, the actuating elements being formed as angular levers which are turnably held in the housing and engage at one end with associated one of the clamping pistons and on the other hand with an associated one of the clamping jaws.

Abstract: A clamping device for objects such as workpieces to be treated and the like has a base body having at least one abutment surface for at least one object to be clamped, at least one clamping finger located on a movable carrier and having at least one clamping surface for at least one object to be clamped, so that a clamping force for clamping the at least one object is applied between the abutment surface and the clamping surface, an actuating element in operative connection with the at least one carrier for applying a clamping force in a clamping direction and opposite to it so that the carrier with the clamping finger being movable in a direction substantiallytransverse to the clamping direction relative to the actuating element, and a bearing block in which the carrier with the clamping finger is held movably relative to the bearing block, the bearing block being displaceble in the base body substantially transversely to the clamping direction.
