ABSTRACT:
For machining a part or a series of parts on a machine tool, it is proposed that said part be successively fixed in at least two different gripping modules (12a to 12e) mounted on a central unit (10) placed on the machining plate of the machine. The rapid assembly and disassembly of the modules with respect to the central unit is ensured by flanging jacks (42a,42c) actuated by a hydraulic control system (14) carried on the central unit. This system (14) also actuates control and locking jacks (34,40,64) ensuring the gripping of the parts on the modules (12a to 12e).
