  • Patent number: 9358652
    Abstract: A tool turret includes a tool disk (2) swivelable about a support column (32) that defines a swivel axis (26) into positions in which at least one machining tool fastened to the tool disk (2) is in a machining position. A drive device (14) includes drives (10, 8) connected by a controllable coupling device (18) to outputs (20, 22) used to drive the tool disk (2) or the machining tool. The drive device (14) is arranged inside the tool disk (2) together with the drives (8, 10) and the output (22) used to drive the machining tool. The output used to drive the tool disk (2) in a swiveling manner has a gear train arrangement (34) outside the tool disk (2) on the support column (32). The gear train arrangement has an output shaft (70) that extends along the support column (32).

  • Patent number: 9233446
    Abstract: A tool turret includes a tool disk (1) having at least one tool receptacle (7) for a machining tool and being fastened to an accommodating disk (51). The disk can be swiveled about a support column that defines a swivel axis into positions in which the particular machining tool is in a working position. A contact surface (55) is provided on the tool disk (1) and can be clamped to an accommodating surface (53) on the accommodating disk (51) by a clamping device. The clamping device has an annular groove on one disk to be clamped. The annular groove is concentric to the swivel axis, is open radially outside and has at least one inner slanted surface (81). At least one compression piece (57) is on the other disk, penetrates the annular groove (61) under compressive force and has a wedge surface (79).

  • Patent number: 9089940
    Abstract: A drive device alternatively drives a tool disk (2) of a tool turret (4) or at least one machining tool fastened to the tool disk (2) by a retaining unit (6). Two drives (8, 10) can be driven by a common drive unit (14) having a drive shaft (12). The drives (8, 10) are connectable to an output (22, 20) by a coupling unit (18) that can be controlled by at least one actuating unit (16). The output is used alternatively to drive the tool disk (2) or the machining tool. The drive unit (14) is arranged inside the tool disk (2) together with the drives (8, 10).

  • Publication number: 20130074301
    Abstract: The invention relates to a tool turret, comprising a tool disk (2), which can be swiveled about a support column (32) that defines a swivel axis (26) into positions in which at least one machining tool that can be fastened to the tool disk (2) is in a machining position, and comprising a drive device (14), the driving means (8, 10) of which can be connected by means of a controllable coupling device (18) to output means (20, 22), which are used to drive the tool disk (2) or the machining tool. Said tool turret is characterized in that the drive device (14) is arranged inside the tool disk (2) together with the driving means (8, 10) and the output means (22) used to drive the machining tool and in that the output means used to drive the tool disk (2) in a swiveling manner have a gear train arrangement (34) outside the tool disk (2) on the support column (32). The gear train arrangement has an output shaft (70) that extends along the support column (32).
