ABSTRACT:
An apparatus for chucking and releasing a conical shank of a tool or an additional aggregate on tool machines, particularly drilling and milling machines. The apparatus has a hollow spindle which is supported in a spindle housing and has at its lower end which faces the conical shank a receiving cone for the shank. A draw rod is supported for axial movement limited by a lower and an upper stop, is rotatably movable in the spindle, has at its end which faces the shank threads which can be screwed into threads on the shank, and is connected at its upper end to a drive motor rotor so as to be fixed against rotation but axially movable with respect thereto. Both stops are provided on a sleeve which concentrically surrounds the draw rod. The sleeve is supported on a spring arrangement. It is movable axially downwardly with respect to the spindle under the action of a hydraulically operated piston against the chucking force of the spring arrangement in a direction toward the receiving cone.
