Definitions
- the invention relates to an internal milling cutter with an annular, equipped on its inner shell with cutting inserts tool carrier, which is mounted in a machine holder.
- Ring-shaped cutter disks with internal cutting edges preferably indexable inserts, have long been known, also with regard to their use in crankshaft milling.
- 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 by pressing the internal milling cutter carrier.
- On the knife carrier or on the milling drum wedges are attached, whose faces are the mating surfaces.
- an internal milling cutter according to claim 1.
- the tool carrier and the machine mount are fastened to one another by means of a bayonet connection.
- a bayonet connection has the special advantage that only a small angle of rotation must be swept over in order to assemble the parts together.
- connection means are structurally simple in construction, easy to manufacture and not susceptible to interference during operation.
- a strip-shaped ring body is used with equidistant projections as part of the bayonet connection, which is detachably screwed to the tool carrier or on the machine holder and together with this forms a groove-shaped partially perforated bayonet guide.
- This ring body can advantageously be easily replaced if wear has occurred as a result of frequent tool change, which no longer allows safe bayonet guide.
- bayonet connections are used, in which the tool carrier on its outer shell 2 to 20, preferably 12 radially projecting projections, which are held on corresponding undercuts of the tool carrier directly or the strip-shaped annular body.
- 12 projections with corresponding abutments are sufficient to create a secure and repeatable same orientation.
- adjustable wedges are preferably used as centering elements, which in the zip are known from the prior art, for example, be described in the aforementioned DE 34 39 978 C1.
- FIG. 1 is a plan view of a tool holder with clamped tool carrier
- FIG. 2 is a sectional view taken along the line A-A in Fig. 1,
- Fig. 3 is a sectional view taken along the line B-B in Fig. 1 and
- Fig. 4 is a partial sectional view with a wedge as centering.
- FIG. 1 Machine tool side is shown in FIG. 1, a machine holder 10 can be seen, which is attached in the usual way to the machine tool.
- This machine mount 10 is fastened with an annular tool carrier 11 via a bayonet connection, which can be released in the direction of the arrow 12 by movement of the internal cutter.
- the tool carrier is fitted on its inner shell and on its side surfaces with indexable inserts whose selection and arrangement depends on the intended use such as roughing or finishing operations on a crankshaft.
- a strip-shaped annular body 13 is used as an additional part to provide a bayonet connection, which has lugs 14 on its outer shell, which abut in corresponding Nuten Entryen the machine holder 10.
- protrusions 15 are provided on the shell inside of the ring body, the z. T. at equidistant intervals through openings 16 (see Fig. 1) are broken. These openings 16 have a width and height, which allows a passage of the radially projecting projections 17 of the tool carrier. By rotation of the tool carrier 11 (opposite to the direction of the arrow 12), these projections are guided in undercut areas of the strip-shaped annular body 13. In the case shown in Fig. 3, the Projections 17 guided in a groove-shaped recess, which is formed on the one hand by a recess in the annular strip body 13 and on the other hand by an opposite recess in the body of the machine holder 10.
- centering element 18 as an adjustable wedge, in which a radial displaceability by means of an eccentric 19 or similarly acting displacement elements is possible.
- This centering element which is known in principle according to the prior art, serves to compensate for any concentricity errors.
