<p>PCT No. PCT/EP86/00367 Sec. 371 Date Mar. 30, 1987 Sec. 102(e) Date Mar. 30, 1987 PCT Filed Jun. 24, 1986 PCT Pub. No. WO87/00466 PCT Pub. Date Jan. 29, 1987.The apparatus according to the invention, for clamping crankshafts in working machines, is addressed to the problem of being able to clamp the workpieces in a defined position, reproducibly and without distortion, even in the case of different rough crankshaft forgings and varying clamping forces. This is made possible by clamping the workpiece not only between centers but also with two additional devices, the crankpins and cheeks of the workpieces being positioned by oppositely acting hydraulic plungers transversely of the long axis of the workpiece, while these two additional clamping devices are housed in a ring which rotates with the workpiece and which is supplied during rotation only through internally present energy accumulating systems.</p> |
