Abstract
A coupling system between a tool system module, such as, for example, a tool receptacle, and a machine tool, such as, for example, a spindle. In order to provide for rapid initiation and release of the connection between these components while making large axial forces available, this incorporates a clamping system with an operating rod, by means of which a wedge drive is controlled, with which clamping elements that are provided in one of the parts that are to be coupled can be forced essentially radially outwards into suitably configured recesses in the other part that is to be coupled. The clamping elements are formed from at least three clamp-like clamping claws that are arranged at equal angular intervals from each other, these being arranged essentially parallel to a centering extension of the tool receptacle; while being supported in a centering recess of the spindle a claw section of these clamping claws that in the coupled state lies radially within the centering extension these can be pivoted into a groove-like recess of the centering extension. This coupling system is distinguished by great flexibility with regard to potential use and by the fact that it can be produced economically.
