ABSTRACT:
A clamping device for a machine table comprises a clamping plate having a receptacle into which a draw-in bolt is insertable through an opening. A clamping mechanism immobilizes the draw-in bolt in the receptacle. A closure cap is movable inside the receptacle between a closed position and an operating position in which the closure cap is pushed into the receptacle by the draw-in bolt. The draw-in bolt is inserted into the receptacle and immobilized with the clamping mechanism. A centering surface is implemented on the end surface of the closure cap facing toward the outer side of the clamping device and/or on the end surface of the draw-in bolt facing toward the inner side of the clamping device. The centering surface pre-centers the draw-in bolt when it is inserted into the receptacle and its end surface thereby comes into contact with the end surface of the closure cap.
