Tool turret

摘要

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). In interaction with the slanted surface (81) of the annular groove (61), the wedge surface produces a force component as a clamping force from the compressive force pressing the contact surface (55) and the accommodating surface (53) against each other.

主权项

1. A tool turret, comprising:
a tool disk having at least one tool holder for a machining tool and having a contact surface, said tool disk being swivelable around a support column defining a swivel axis during moving the machining tool in said at least one tool holder into and out of a working position; a receiver disk fastened to said tool disk by a receiving surface of said receiver disk being clamped to said contact surface of said tool disk; and a clamping device clamping said receiving surface to said contact surface, said clamping device including an annular groove on one of said disks and a pressure piece on the other of said disks, said annular groove being concentric with said swivel axis and being radially open outwardly relative to said swivel axis and having at least one inclined surface, said pressure piece penetrating said annular groove under a compression force and having a wedge-shaped surface interacting with said at least one inclined surface to generate a force component as a clamping force from the compression force, said clamping force pressing said contact surface and said receiving surface against each other to clamp said tool disk to said receiver disk.
