ABSTRACT:
The clamping device comprises a housing and an anchoring device for fixing the housing to the table of a machine tool. A jaw for clamping the work to be machined to the table and a lever extending the jaw are both pivotally mounted on a pivot pin carried by the housing. An actuating device engages one end of the lever for shifting the lever about the pivot pin and is accessible from outside the housing. A detachable coupling device renders the lever rigid with the jaw in any one of a number of relative angular positions so that, when the actuating device shifts the lever, the lever and the jaw move together for clamping the work. A spacer block can be combined with the clamping device. The block has on its top side a cavity for receiving the anchor device of the clamping device and a lock member for engaging an aperture in the housing. The block has a bottom side provided with an anchoring device identical to the anchoring device of the clamping device and with an aperture for receiving the lock member of an identical spacer block placed thereunder. Consequently, a plurality of superimposed spacer blocks may be employed.
