摘要

The present invention relates to a machine tool with a tool changing device and a tool changing device for changing a tool 10a on a spindle 101 of a machine tool, comprising a is mounted in 2 with a plurality of peripheral tool bit chucks 2a, 2b, 2c, to pick up tools 10a, 10b, 10c, an axle carrier 3, on which the mounted in 2 to the alignment of the tool bit chucks 2a, 2b, 2c with the spindle 101 is rotatably mounted, a first coupling means 6, 6a, 7, which is rotatably mounted on the axle carrier 3 is mounted, and at least one first gear stage 4, 5, via which the first coupling means 6, 6a, 7 is mounted in 2 is connected with the. The first coupling means 6, 6a, 7 is for this purpose is arranged with a second coupling means 106a a - or to be disengaged, which is rotatably mounted on a spindle head 104 of the machine tool is mounted and via at least one second gear stage 105, 106b with the spindle 101 of the machine tool is connected, and wherein the mounted 2 is adapted, in the coupled state of the first and second coupling means 6, 6a, 7, 106a by means of the spindle 101 of the machine tool via the at least one second gear stage 105, 106b, the second and first coupling means 106a, 7, 6a, 6 and the at least one first gear stage 5, 4 to the alignment of the tool bit chucks 2a, 2b, 2c to be driven.
