Sitzmann & Heinlein GmbH, Bahnhofstr. 11-13, 8502 Zirndorf "Planing tools"

The invention relates to a planing tool for the machining of profiles on preferably elongated ones Workpieces such as rails, switches or the like, especially on long planing machines Interchangeable cutting tools, in particular indexable inserts, fastened to a planer holder.

For the machining of profile surfaces on elongated workpieces such as rails, V / eichen, switch tongues or the like. In rail production or Repair shops use planing tools, each of which has one assigned to a specific profile Configuration of cutting tools is arranged. A large planer holder must therefore be provided for each profile which has to be exchanged for a different planer holder when machining other profile surfaces. That Reclamping the planer holder is time-consuming and labor-intensive due to the size and weight of the planer holder additionally requires the use of lifting tools.

The invention is based on the object to provide a planer holder with the various

- 2 profiles or profile surfaces can be optionally processed

According to the invention, this object is essentially achieved with a planing tool of the type explained at the beginning solved in that on a holder shaft in a recess forming a support and a system, at least a cassette with attached cutting tools is screwed so that the cutting tools at the (the) Cassette (s) are designed and arranged analogously to the profile to be machined and clamped by holding means.

The inventive design is at the transition from one profile surface to the other profile surface It is no longer necessary to change the planing tool, but all that is required is those arranged in the same way with the corresponding profile Replace cutting tools provided cassettes, which in a simple manner for a short time and without Use of additional lifting tools is enabled.

According to an advantageous embodiment of the invention, each cassette is in the recess of the holder shaft A wedge guided in keyways is assigned to the support and the system. This creates a secure connection between the holder shaft and the cassette, the cutting forces and side forces being added without tilting or other twisting of the cassette (s) in the recess.

When using indexable inserts as cutting tools, it is advantageous if the inserts are designed as indexable inserts Cutting tools are guided by means of locating bolts and held by means of clamping claws. Through this It is possible to train the cutting elements each

Individual cassette can easily be exchanged or a new cutting edge can be used by twisting it.

For processing larger profile surfaces, such as rail heads, switch blades or the like According to a further embodiment, it is the He

Finding advantageous if a profile steel held in a dovetail by means of a cover is provided as the cutting tool is.

In yet another embodiment of the invention,

in the case of wide profile surfaces, a double cassette is used as a carrier for the profile steel, which can be extended over, for example the width of the holder shaft extends.

In order to have a suitable cassette available for each profile, it is useful if the W end plates on a cassette according to the profile to be machined in height, side and depth accordingly are arranged.

Further advantages and features of the invention are explained in more detail with reference to the drawing, which schematically Represents exemplary embodiments. It shows:

1 and 2 show an embodiment of a planing tool according to the invention in side or front view, Fig. 3 shows a modified embodiment of a cassette according to the invention,

4 shows a further exemplary embodiment for processing larger, in particular three-dimensional profile surfaces, and

Fig. 5 shows yet another embodiment of a cassette according to the invention.

In the embodiment shown in Figs. 1 and 2 are on a holder shaft 1, which has bores 2 and 3 is provided for fasteners for connection to a planing machine, in a support Ö and a recess 7 forming a system at the lower end of the holder shaft 1, two cassettes 12, 13 by means of Fastening screws 14 and 15 arranged. Keys 8 and 9 are provided in keyways 10 and 11 ', 11 ".

To connect the cassettes 12, 13 to the holder shaft, threaded bores 16 of the holder shaft 1 are used Fastening screws 14, 15

The height, side and depth of the cassettes 12, 13 are offset according to the profile to be machined or staggered V-end plates 17 are arranged. These inserts 17, for example square inserts with a central opening, are clamped by clamping claws 18, which in turn are fastened with fastening screws 19 in the cassettes 12 and 13, respectively. Appropriate Locating pins 20 are provided which engage in central openings in the indexable inserts 17 and the indexable inserts 17 secure in a respectively defined position.

From Fig. 2 it can be seen that the planing tool shown, for example, for machining profile surfaces can be determined on switches or rails 21 ', 21 ".

In Fig. 3, a modified embodiment of a cassette 22 is shown, which for processing A corresponding profile surface on a rail 21 '"is used. A profile steel is in a dovetail 25 clamped by means of a cover 27 and a fastening screw. The cassette 22 has a bore 23 for (not shown) fastening screws and a keyway 24 for a (not shown) fitting key. In the embodiment according to FIG. 4, a profile steel is used for machining larger, three-dimensional profile surfaces 30 fastened to a double cassette 29 by means of a cover 31 and a fastening screw 32. the Double cassette 29 extends over the entire width of the holder shaft 1. The design of the holder shaft 1 can be unchanged the same as in the embodiment according to FIGS. 1 and 2, with only instead of the two cassettes 12, 13, a double cassette 29 is provided. In this embodiment, too, are again wedges 8,9 guided in keyways are provided.

In FIG. 5, a further exemplary embodiment of a cassette 33 is shown, with a keyway 34 and a fastening bore 35. Cutting elements in the form of indexable inserts 37 are by means of clamping cover 36 in the same way as in the embodiment of FIGS. 1 and 2, but in a graduation corresponding to another profile attached.

The various cassettes 12, 13 or 22 or 33 can easily be attached to the holder shaft 1 and easily removed.

be changed. All you have to do is use the fastening screws 14 or 15 are loosened or tightened.

By suitable selection or combination of different cassettes with different configurations of the cutting tools different profile surfaces can be machined at the same time, for example for switches with tongues.

It is therefore necessary to adapt to different profiles and to exchange or rotate the cutting tools only required to replace the corresponding cassettes, while the heavy holder shaft 1 on the Planer or the like can remain.

If a replacement of the holder shaft 1 is desired, this only has to be done by the one in the bores 2, 3 arranged fastening means are separated. For example, it is held on the planing machine by means of threaded bolts (not shown) and Fasteners. A bolt 4 is arranged on the holder shaft 1 so as to be pivotable about a retaining screw 5, with Recesses which partially cover the cross section of the bores 2, 3. This makes it possible to use the fastening nuts to be left on the holder shaft 1 even after the holder shaft 1 has been unscrewed from the planing machine.

The invention is not limited to the illustrated and described exemplary embodiments, it also includes all professional modifications and further developments as well as partial and sub-combinations of the described and / or features and measures shown.
