Abstract
The invention relates to a tool holding system for automatic tool changing in a machine tool, stamping machine or other such machine, wherein the machine has a spindle which has at its free end a gripping means in the form of a sleeve for a tool which can be inserted and removed by a tool changing system, while a draw rod actuating the sleeve by axial displacement is guided in the spindle, and the tool having at the spindle end a tool holding head with an inverted centering frustum cone which can be engaged by a conical inner surface of the sleeve in its clamping position in order to clamp the tool against the spindle. The new tool holding system according to the invention is characterized in that the sleeve is provided with a T-shaped slot open at least at one end, that the spindle end has at least on one side a T-shaped or rectangular slot and that the slots of the sleeve and spindle end are positionable in alignment with one another permitting the introduction and removal of the tool holding head from the side. With the invention the tool changing is simplified and expedited.
