Definitions
- the invention relates to a device for fastening an annular Fräswerkmaschineschis, especially in an inner cutter, on a machine holder.
- Ring-shaped cutter disks with internal cutting edges have long been known, also with regard to their use in crankshaft milling.
- the milling disc described in DE 26 34 030 A1 consists of two detachably interconnected circular ring halves, each having a arranged in stepped recesses connecting tab at two joints, wherein at least one circular ring half receives in its recess a centering, connected to the screw via a cone piece is, which engages in an associated conical recess of the connecting plate.
- DE 34 38 978 C1 describes a fastening device for an internal milling cutter carrier on the receiving flange of the milling drum of a crankshaft milling machine by means of locking elements which can be brought into abutment against the receiving flange of the milling drum with mating surfaces on the respective other part while pressing the internal milling knife carrier.
- the wedge surfaces are the mating surfaces.
- slidable wedges are arranged as locking elements, in each case an eccentric is provided as a displacement drive for the movable wedge in such a way that the combination of the eccentric with the wedge is self-locking.
- a tool for external milling which has on the outer periphery several cutting inserts or cassettes equipped with cutting inserts, which are arranged on an annular or partially annular, segment-shaped fixed support, either directly on a machine spindle or indirectly Is detachably fixed via an adapter.
- fastening means and clamping means are screws, clamping wedges or bayonet connections. All of the above mounting options are relatively expensive, which makes tooling complicated and expensive and difficult to handle the cutter when changing tools.
- a threaded connection is provided between an annular milling tool carrier, in particular an inner milling cutter ring and the machine holder.
- a threaded connection can be handled easily and quickly, since the loosening and tightening of otherwise required in the prior art additional locking elements is eliminated. Also manufacturing technology, there are advantages, especially since few built-in parts are needed. By forming the carrier body as a ring, a weight saving is finally achieved, through which a loading crane is dispensable when changing tools.
- the annular milling tool carrier is provided with an external thread and the machine receptacle is provided with a correspondingly formed internal thread.
- the male thread is made multi-homed to allow “easy mating,” i.e., easier assembly.
- the Fräswerkmaschinechtyour has a stop surface which determines the axial position relative to the machine holder in the clamping state.
- this stop surface is formed as an annular end face, preferably adjacent to a short-tapered centering.
- the centering pin facilitates the introduction of the annular Fräswerkmaschine Wegmikrajs on or in the machine holder.
- the milling tool carrier is screwed in, wherein an exact axial positional fixation of the Fräswerkmaschine Wegmikrajiss is achieved with respect to the machine tool by said frontal stop.
- the Fräswerkmaschinechtessentially can be additionally secured against rotation relative to the machine holder, for example via a screw or a clamping wedge.
- the cutter tool body is provided on the side facing away from the machine with at least two blind holes or tapped holes for receiving pins or screws of a bar-shaped handle element.
- the handle member preferably spans diagonally the annular Fräswerkmaschinemaschinerion redesign in the assembled state and can be used as a rotation aid for screwing and unscrewing. As far as the connection between this rotation aid and the annular Fräswerkmaschinechta is fixed, such as by screws, the rotation aid can also be used as a carrying aid for transport.
- Fig. 3 is a cross-sectional view of a Fräswerkmaschinechtns and
- Fig. 4 is a plan view of this Fräswerkmaschinemaschinens and
- Ring-shaped Fräswerkmaschinechta are known in principle according to the prior art, so that in the below described Figures 1 to 5 is received only on the essential, given prior art differences.
- a milling tool carrier 10 is connected to the machine mount 11 via a threaded connection 16.
- cutting inserts arranged on the inner periphery of the milling tool carrier 10 have been omitted. These cutting inserts are usually connected via a clamping screw in a respective cutting plate seat, which may also be part of a cassette attached.
- Cutting inserts used are indexable inserts that are replaced after wear.
- the entire milling tool carrier is released, removed and replaced with a
- the tool ie the cutting insert change on the removed Fräserlism entrepreneurial can be performed independently of the milling machine.
- the milling tool carrier 10 has an end-face abutment surface 12 as an abutment collar, furthermore a short-conical centering pin 13 whose lateral surface 14 has a cone angle of 7 ° to 8 °.
- the thread 15 is formed as an external thread.
- diametrically opposite blind hole threaded holes may be provided which serve as a mounting location for the ends of an elongated handle with corresponding holes through which the screw attached and in the threaded holes 17 and 18 is screwed.
- This bow-shaped handle serves as a rotation aid and can also serve as a carrying aid during transport of the milling tool carrier to the storage location or from the storage location to the machine tool due to its attachment to the Fräswerkmaschinecht.
- the embodiment described above is particularly suitable for internal cutters of smaller design, in which the weight of the milling carrier body is about 15 kg, so that a handling without loading cranes or similar aids "per
- the embodiment of a threaded connection according to the invention can also be used in so-called external cutters in which the tools (cutting inserts) are arranged peripherally on the outside of the annular tool carrier. that corresponds with an external thread a machine holder.
