| 摘要 |
The invention relates to a rotatable tool intended for chip removing machining comprising two parts, viz. a holder part (1), rotatable around a geometrical centre axis (C), as well as a replaceable cutting part (2), which is rigidly connectable to a front end of the holder part via a male/female coupling in the form of a tapering seat (5) in the holder part and a tapering male member (14), protruding from the cutting part. In connection with the seat, there is a slot (6), which separates two elastically deflectable projections (7, 8), that may be inwardly deflected towards each other during clamping of the male member (14) in the seat (5). According to the invention, the male member consists of a sheath-like body (14) and the seat of a radial, laterally open guiding groove (5) into and out of which the sheath body is transversely movable, whereby at least one external wedge surface (20) of the sheath body (14), inclined in relation to the centre axis (C), is arranged to interact with an internal, wedge surface (25), which defines the guiding groove. Furthermore, the sheath body and the guiding groove comprise means (26, 27) for centring the sheath body in a predetermined position along the guiding groove.The sheath body and guiding groove include in addition means (26, 27) for centring the sheath body in a predetermined position. <IMAGE> |
