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 work-pieces 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.
Appareil pour serrer des pièces à travailler qui doivent être usinées par une machine-outil. L'appareil comprend un châssis rectangulaire incluant deux éléments longitudinaux et deux éléments transversaux. Des dispositifs de serrage servent à fixer les pièces à usiner au châssis rectangulaire. Ils comprennent au moins un châssis auxiliaire inséré de façon non permanente dans le châssis rectangulaire. Chaque châssis auxiliaire comporte deux traverses de serrage qui peuvent être raccordées de façon réglable l'une à l'autre et dont les extrémités sont adaptées pour être raccordées aux éléments longitudinaux du châssis rectangulaire de façon à être réglables dans le sens longitudinal du châssis longitudinal. Les traverses de serrage comprennent de nombreux alésages filetés continus, essentiellement perpendiculaires aux traverses de serrage, élargis à un diamètre nominal prédéterminé et adaptés pour recevoir sélectivement une vis de serrage.
