Abstract
The invention includes a clamping system for a workpiece on a measuring machine, with a multiple-jaw clamping chuck. A rotary drive rotates the multiple-jaw clamping chuck. The rotary drive includes a stator and a rotor. The multiple-jaw clamping chuck has a chuck body wherein the clamping jaws are radially movable for clamping a workpiece or loosening it from the clamping chuck, a flat spiral mounted rotating relative to the chuck body in positive engagement with the clamping jaws, and an outer rim rotating with respect to the stator. The flat spiral is firmly joined to the rotor of the rotary drive, but can turn relative to the chuck body in order to move the clamping jaws radially inward or outward. Using a coupling, a part of the clamping system can be secured so that the rotary drive takes on the function of adjusting the clamping jaws.
