<p>A mechanism for coupling tooling cassettes (60) in a numerical control machining unit for a transfer machine of the type comprising a frame (10) with rails (11, 12) for moving (X arrow) a vertical knee (20) with two posts (21 and 22) also provided with rails (21a and 22b) on which a movable headstock (30) slides (Y arrow), with a spindle-supporting slide (40) passing through the headstock (Z arrow); and a magazine (50) for a tooling cassette (60) positioned on the headstock (30), surrounding the knee (20), and through which the slide (40) may pass, comprising a ring (5) supporting the cassettes (60) and rotatably mounted (R arrow) about the knee (20). The mechanism for coupling the cassettes (60) bears on the rotation guide (R arrow) of the ring (51) of the rotating magazine (50) around a circular track (52) integral with the frame (10) and provided at its base with a triangular way (52a) with rollers (62a, 62b) retained and guided therein, wherein said rollers are associated with said cassettes (60) for rotating with the cassettes (60) driven by the ring (51). The invention is useful for transfer machines, machining cells and the like.</p> |
