ABSTRACT:
Described is a coupling device between a workpiece support or a tool support, such as for example a tool system module, for example in the form of a basic tool holding fixture, and a handling device, such as for example a machine tool, especially a spindle. For rapidly producing and releasing the connection between these components while making high axial forces available, a clamping device with an operating rod is provided by which a key mechanism is controlled, with which clamping elements provided in the part to be coupled can be pressed essentially radially outward into a suitably shaped recess on the other part to be coupled. The clamping elements are formed from at least three clamplike claw-type clamps placed at a uniform angular distance to each other, placed essentially parallel to a centering extension of the basic tool holding fixture and able to be pivoted, while being braced in a centering mounting of the spindle with a claw section lying radially inside the centering extension in the coupled state, into a groovelike recess of the centering extension. This coupling device is distinguished by a high flexibility with regard to application possibilities for producing them economically.
