Disclosed is a coupling for machine tools, comprising a first main coupling part (1) and at least one additional main coupling part (2) for mechanically fastening an attachment (4) to the machine tool. A first power coupling part (5) is provided on the first main coupling part (1) and at least one other power coupling part (6) is provided on the additional main coupling part (2) in order to supply power to the attachment (4) or the machine tool. Furthermore, an actuator (7) which is used for actuating a locking mechanism (8) that interlocks the two main coupling parts (1, 2) is disposed on one of the main coupling parts (1, 2). A connecting device (9) is provided for automatically connecting the power coupling parts (5, 6). Said connecting device (9) for the power coupling parts (5, 6) is fitted with at least one spline (20) which can be preferably moved in a linear manner and slides the power coupling parts (5, 6) onto one another for connecting purposes by means of a wedging surface (21). The power coupling parts (5, 6) are each equipped with at least one power coupling plate (16, 17), on each of which female and male power coupling elements (18, 19) are arranged that can be engaged with one another. The wedging surface (21) of the spline (20) acts upon a wedge-shaped guiding surface (22) of the power coupling plate (16) of the first power coupling part (5) and moves the power coupling plate (16) relative to the first main coupling part (1). |
