Abstract
An apparatus for clamping workpieces which have to be machined by a machine tool. The apparatus comprises a rectangular frame including two longitudinal frame members and two transverse frame members. Clamping means are provided to fix the workpieces to be machined to said rectangular frame. The clamping means comprise at least one auxiliary frame which is removably inserted in said rectangular frame. Each of the auxiliary frames includes two clamping bars which can be adjustably connected to each other and the ends thereof being adapted to be connected to the longitudinal frame members of the rectangular frame such that they are adjustable in the longitudinal direction of the longitudinal frame. The clamping bars comprise a plurality of continuous threaded bores running essentially perpendicular to the clamping bars, said bores being enlarged to a predetermined nominal diameter and said bores being adapted to selectively receive a clamping screw.
