Abstract
A positioning device positions a tool holder (12, 14, 16, 18) on a tool turret (6) of a machine tool by positioning pins (10). The positioning pins are secured to the tool turret (6) and engage with receptacles (40) on the tool holder (6) when the tool holder (12, 14, 16, 18) is attached to the tool turret (6). At least one of the receptacles of the tool holder (6) is formed by a sleeve (40), with which the assignable positioning pin (10) engages in the mounted state while contacting the inner circumferential surface (58) of the sleeve (40). The inner circumferential surface (58) is part of an expanding part (56), which, when the pin (10) engages, expands elastically and flexibly away from the pin (10).
Claims11
A positioning device, comprising:
- a tool turret of a machine tool;
- a tool holder on the tool turret;
- a first positioning pin being secured to the tool turret and engaging a receptacle on the tool holder when the tool holder is attached to the tool turret, the receptable on the tool holder having a first sleeve engaging the first positioning pin, when the tool holder is in a mounted state in which the tool holder is attached to the tool turret, while the first positioning pin is contacting an inner circumferential surface of the first sleeve, the inner circumferential surface being part of an expanding part that expands elastically and flexibly in a direction away from the first positioning pin when the expanding part is engaged by the first positioning pin, both the first positioning pin and the first sleeve being fixed in the tool turret and in the tool holder, respectively, by a respective screw, connection, both the first positioning pin and the first sleeve having a respective continuous hollow duct, a respective point of action for an operating tool being within each of the hollow ducts, and the first positioning pin resting against the tool turret via an annular support part that is outside of the corresponding screw connection, and the first sleeve resting against the tool holder via an annular support part that is outside of the corresponding screw connection;
- and
- a bending rod of a fixer, the bending rod releasably retaining the tool holder on the tool turret and extending through the hollow duct of the first sleeve and into the hollow duct of the first positioning pin.
A positioning device, comprising:
- a tool turret of a machine tool;
- a tool holder on the tool turret;
- a first positioning pin being secured to the tool turret and engaging a receptacle on the tool holder when the tool holder is attached to the tool turret, the receptacle on the tool holder having a first sleeve engaging the first positioning pin, when the tool holder is in a mounted state in which the tool holder is attached to the tool turret while the first positioning pin is contacting an inner circumferential surface of the first sleeve, the inner circumferential surface being part of an expanding part that expands elastically and flexibly in a direction away from the first positioning pin when the expanding part is engaged by the first positioning pin, the first positioning pin and the first sleeve being fixed in the tool turret and in the tool holder, respectively, both the first positioning pin and the first sleeve having a respective continuous hollow duct;
- a fixer detachably fixing the tool holder to the tool turret, one free fixing end of a bending rod of the fixer being secured to the tool holder;
- and
- in the mounted state in which the tool holder is attached to the tool turret, a free latching end of the bending rod extending under a projection of the first positioning pin in the hollow duct of the first positioning pin, the latching end of the bending rod passing through the hollow duct of the first sleeve and being actuatable by an actuator and coming out of engagement with the projection of the first positioning pin to release the tool holder from the tool turret and to allow the tool holder to be removed from the tool turret.
