Abstract
1377711 Grinding crank-shafts; turning crankshafts; machine tool details TOS HOSTIVAR NARODNI PODNIK 3 Jan 1972 [4 Jan 1971] 169/72 Headings B3D B3B and B3T A machine tool for machining heavy counterbalanced crank-shafts 9 comprises a rear bed 1 having two headstocks 3 and a rest 10 for stationary supporting a crank-shaft; a front bed 2, a slide 13 longitudinally movable on the front bed, a saddle 4 on the slide and carrying a part circular guide 14, a rotary body 18 mounted within the guide and having an adjustable machining means 24, and means for rotating the body within the guide, the guide and body having openings 43 which, when aligned, permit the guide and body to be moved to a position surrounding the crank-shaft mounted in the headstocks. Each headstock has jaws 7 for clamping a flange of the crank-shaft to a chuck 6 which is rotatable by a drive 20 to positions determined by pawls 31 engaging grooves 32 to position the crank-shaft for machining. One or more supports 10 are positioned on the rear end for supporting the crank-shaft. The slide 13 is longitudinally movable along the front bed 1 by an electric motor and gear-box 16, and the saddle 4 is movable on the bed transversely by hand or mechanical feed, a cover 17 protecting the guideways. The guide 14 is carried by the saddle and is part circular with an opening 43, which can be closed by a hinged member 28, and the body 18, which has a similar opening 43, is mounted within the guide and has a toothed wheel engaged by gears 19 driven by wormwheel mechanism from a common shaft driven by a belt 22 from a two-speed motor, the spacing between the gears being greater than the width of the opening 43 so that one gear at least is always engaging the wheel. The body carries a machining element in the form of a lathe cutter or a cup-shaped grinding wheel 24 which is rotated by an electric motor and fed radially inwardly or outwardly of the body by a screw rotated in one direction or the other by pawl- and-ratchet mechanisms (Fig. 4, not shown) actuated by electromagnets. The body also carries a finishing element 25 having stones mounted in a resilient holder and oscillated by an electric motor.
