The invention relates to a device for changing of tools into the work spindle of a machine tool. It includes a two-arm changing arm, the axis of rotation of which is positioned at an angle of 45 DEG with respect to the work spindle, and the gripping ends of which are angled each at 45 DEG toward the axis of rotation. The tools are inserted into the changing arm with the ends, which are to be inserted into the spindle, pointing away from the axis of rotation, so that, in particular when using long tools, a smaller flight circle and thus a smaller collision free space, which is to be kept free, results. Therefore, the device is particularly suited for machine tools with two spindles. The entire changing arm with its support, which permits the change rotation and the pulling out and inserting movement of the tool out of and into the spindles, is pivotal about an axis which extends perpendicularly with respect to the plane which is defined by the spindles. With this the device can be changed over with one single pivoting movement to the different spindle directions. |
