ABSTRACT:
A system for the assembly of devices for fixing workpieces to machine tool tables, including a base plate, which can be fixed to the machine tool table, or the like. Fitting holes are formed in the base plate with regular coordinate spacings. In the base plate, in a plane at right angles to the fitting holes, are formed preferably intersecting cross holes, whose diameter corresponds to that of the fitting holes. Nuts for the fitting screws are inserted both in the cross holes and the fitting holes, in order to fix mounting parts to the base plate. The cross-section of each nut corresponds to that of each cross and fitting hole. The mounting parts are preferably provided with cross and fitting holes similar in arrangement to the base plate. As the grid size corresponds to the thickness of the base plate and mounting parts and the external dimensions can be divided by the grid size, numerous possible combinations result from the intersecting fitting and cross holes, whose diameter preferably corresponds to half the grid size.
