Abstract
The tool turret comprising driven tools comprises a turret shaft (2) which carries the turret plate (4) and is supported in a turret housing (1) so as to be rotatable and axially displaceable. The turret shaft (2) can be locked at the turret plate end by a Hirth coupling. At the other end, the turret shaft (2) can be connected via a switchable coupling with a toothed wheel (23) of a gear unit (15) so as to be fixed with respect to rotation relative to it, the toothed wheel (23) being supported coaxially relative to the turret shaft (2). A switchable intermediate wheel (26), which engages with a pinion (27) of a drive shaft (28) for the tools to be driven, can engage with the coaxial toothed wheel (23). The turret shaft (2) can be displaced axially into its two end positions by a double-action piston (6), the couplings (12, 13) connected with the turret shaft (2) being alternately engaged and disengaged in the two end positions. For the purpose of swiveling the turret plate, the turret shaft (2) is connected with the coaxial toothed wheel (23) via the coupling (24, 25) so as to be fixed with respect to rotation relative to it, whereas the switching wheel (26) is disengaged from the …
