Stangenzuführvorrichtung für eine Werkzeugmaschine, insbesondere einen Drehautomaten

摘要

The equipment comprises a final station and four intermediate stations (7-10). The penultimate station (7) has a bar guide (4) which opens on the action of a cam (51,54) driven rod (52) to allow the entry of bars (2) from a tray (56). The bars are initially positioned against a cam operated lever (73,75) at the penultimate station (7) by the action of a grab (40) at an intermediate station (8) which is operated by a longitudinal cam (46,47). The outer end (24) of the bar (2) is seized by a rotatable grip (23) and carried towards the lathe by a motor driven endless chain (25). The cams are rotated by a motor (33) driven camshaft (12) and the operation of the equipment is coordinated by an electronic unit (31) using sensors (30,35).
