A coupling device between a modular tool system, for example the receiver of the base of a tool, and a machine-tool, for example a spindle (4). To ensure rapid coupling and decoupling of these components by applying high axial forces, a clamping arrangement includes an actuating rod (20) which controls a wedge drive capable of pushing clamping elements from a part to be coupled radially outwards into a recess of matching shape. The clamping elements consist of at least three clamping claws (24) mutually offset at a constant angle, arranged parallel to a centering prolongation (12) of the receiver of the base of the tool, and pivotable in a slot (36) in the centering prolongation (12) on a section of the claw (26) which penetrates radially into the centering prolongation in the coupled state by pressing against a centering receiver (18) of the spindle (4). This coupling arrangement has numerous potentiel fields of application and can be economically manufactured. |
