Abstract
A workpiece-clamping element has a cylinder and a lifting rod assembly guided in the cylinder with an annular piston and with an inner tube. The lifting rod assembly carries a suction plate having a workpiece support surface. A workpiece table has a plurality of workpiece-clamping elements of this type. A cylinder bottom of the cylinder penetrated by the lifting rod assembly, the lifting rod assembly and a cylinder jacket tube of the cylinder delimit a pressure chamber. In addition, the lifting rod assembly is mounted both in the cylinder bottom and in the cylinder head so that it can be displaced at least axially. The present disclosure allows a short changeover time and a shortened throughput time of workpieces.
