Description

11Fraswerkzeur11i Die Erfindung betrifft ein Fräswerkzeug insbesondere für kleine Zinken-oder Keilzinkennrofile. 2ür kleine Zinken oder Keilzinken-Profile ist die Verwendung einzelner Fräserscheiben aufwendig und kostsnieli g. Die Erfindung löst diese Aufgabe in besonders ein--:a#c1.ier Weise dadurch, daß in eine Welle mit einer oder mehreren Schwalbenschwanznuten auf genaue Dickentoleranz plangeschliffene Fräserzähne paketweise eingeschoben werden, durch Klemmschrauben gegeix justierten axialen Anschlag gedrückt werden, und anschliessend -in nn sich be1.:annter Weise durch hydraulische Mittel insbesondere durch einen Druckschlauch in radialer Weise in dieser Schwalbenschwanzn ut nach außen gec1rücl:", werden.11Milling tool 11i The invention relates in particular to a milling tool for small finger or finger joint profiles. 2 for small teeth or finger joint profiles the use of individual milling disks is complex and costly. The invention solves this problem in a special -: a # c1.ier way by being in a wave Flattened with one or more dovetail grooves to an exact thickness tolerance Cutter teeth are inserted in packets, adjusted against each other by clamping screws axial stop are pressed, and then -in nn in the same way by hydraulic means in particular by a pressure hose in a radial manner in this swallowtail groove, it is turned outwards: ", be.

Auf diese Weise können besonders vorteilhaft Fräserzähne aus Hartriletall verwendet werden, wobei das Auflöten des Hartmetallschneidzahnen auf ein Trägerwerkzeug eingespart wird.In this way, milling teeth made of hard metal can be particularly advantageous be used, with the soldering of the hard metal cutting teeth on a carrier tool is saved.

Die F,..ruren erläutern die Erfindung nähert Figur 1 zeigt schematisch den Querschnitt durch eine erfindungsgemäße Fräswelle mit eingesetzten Schneidzähnen und Figur ?_ zeigt den Teil einer Seitenansicht der gleichen Fräswelle. In Figur 1 sind in die Fräswelle 1 die Schwalbenschwanznuten 2 eingearbeitet, in welche die Schneidzähne,3 und 4 eingesetzt sind und durch die Druckschläuche 5 durch hydraulische Mittel radial nach außen gepresst werden. Mechanische Mittel zum axialen Festklemmen der Schneidzähne innerhalb der Schwalbenschwanznuten 2 sind nicht dargestellt, da nie zum normalen Stand der Technik gehören.The figures explain the invention approaching Figure 1 shows schematically the cross section through a milling shaft according to the invention with inserted cutting teeth and Figure? _ shows part of a side view of the same milling shaft. In figure 1, the dovetail grooves 2 are incorporated into the milling shaft 1, in which the Cutting teeth 3 and 4 are inserted and through the pressure hoses 5 by hydraulic Medium are pressed radially outward. Mechanical means for axial clamping the cutting teeth within the dovetail grooves 2 are not shown because never belong to the normal state of the art.

In Figur 2 ist die gleiche Fräswelle in der Seitenansicht zu sehen, wobei die Präszähne 3 ein Keilzinkenprofil erzeugen Mollen, während die Fräszähne 4 für ein normales Flachzinkenprofil vorgesehen sind. Die Fräszähne 3 für das Keilzinkenprofil sind so vorgesehen, daß jeweils ein 2. Satz entsprechender Fräszähne um 1/2 Zinkenkeilung versetzt in der gegenüberliegenden Nut angewendet werden muß. Zum gleichzeitigen Abrichten der Zinkenspitzen ist die Zusatzschneide 6 an den Fräszähnen 3 vorgesehen.In FIG. 2, the same milling shaft can be seen in a side view, the precision teeth 3 producing a finger joint profile, while the milling teeth 4 are provided for a normal flat joint profile. The milling teeth 3 for the finger joint profile are provided in such a way that a second set of corresponding milling teeth must be used in the opposite groove offset by 1/2 joint wedge. The additional cutting edge 6 is provided on the milling teeth 3 for the simultaneous dressing of the tine tips.
