Kupplung für Werkzeugwechselvorrichtung.

摘要

A tool (12) is releasably supported on a head (10) by a kinematic support (35) having elements (36,37) provided respectively on the head (10) and the tool (12) and extending in a plane (A-A) transverse to an axis 10A) of the head (10) by a releasable coupling (17) which comprises a first element (21) provided on the head (10) and engaged with a second element (26) provided on the tool. To release the tool (12) from the head (10) the latter is moved to position the tool (12) at a magazine (16) and by such movement to connect the second element (26) with an operating member (41) provided on the magazine (16). Rotation of the second element (26) by the operating member (41) releases the second element (26) from the first element (21) and frees the head (10) for withdrawal in the direction of its axis (10A). To connect the tool (12) to the head (10) the latter is moved in the direction of its axis (10A) to bring the elements (36,37) of the kinematic support (35) into proximity and to bring the coupling elements (21,26) into proximity. The operating member (41) is then rotated to connect the coupling elements (21,26) and establish engagement of the kinematic support (35). Thereafter the head (10) can be moved to remove the tool (12) from the magazine (16).
