Abstract
A clamping device includes a clamping chuck and a clamping element, which can be clamped thereto. The clamping chuck has a receiving opening for the clamping element and clamping members for clamping the clamping element in the receiving opening. The clamping element is elongated, while the clamping chuck is provided with an elongated receiving opening for the clamping element. A resiliently flexible centering element, which aligns the clamping element in response to the insertion into the receiving opening at right angles to the longitudinal axis of the receiving opening, is arranged on the clamping chuck in the insertion area of the receiving opening. Such a clamping device is suitable in clamping systems by means of which large to very large workpiece carriers can be clamped in the work area of a machine tool in a repeatably accurate manner.
