Description

Das Festspannen von Stählen in den gebräuchlichen Fräs- und Messerköpfen geschieht bisher durch Keile, konische Stifte, konische Schrauben oder durch Einklemmen konischer Keile. Diese Art des Einspannens hat verschiedene Nachteile, nämlich: das Feststellen der Stähle ist umständlich und ein ungewolltes Verschieben derselben leicht möglich; auch die Befestigung ist nicht solide, und der Tragkörper wird bei wiederholtem Herausnehmen der Zähne beschädigt.The clamping of steels in the common milling and cutter heads is done up to now by means of wedges, conical pins, conical screws or conical clamping Wedges. This type of clamping has several disadvantages, namely: locking the steels are cumbersome and they can easily be moved unintentionally; even the attachment is not solid, and the support body will with repeated removal damaged teeth.

Demgegenüber bestehen die Vorteile dieser Erfindung darin, daß ein einfaches und sicheres Einklemmen der Stähle, auch Einspannen nach Lehre z. B. für bestimmte Nuten möglich ist. Ferner können keine Beschädigungen des Fräskopfes eintreten.In contrast, the advantages of this invention are that a simple and safe clamping of the steels, also clamping according to teaching z. B. is possible for certain grooves. Furthermore, there can be no damage of the milling head.

Der Erfindungsgegenstand ist in Abb. 1 imThe subject of the invention is shown in Fig. 1 in

Grundriß, in Abb. 2 im Schnitt dargestellt.Ground plan, shown in section in Fig. 2.

Abb. 3 zeigt das Festklemmen des Werkzeuges.Fig. 3 shows the clamping of the tool.

Der Stahl 2 wird mit dein Spannhebel 3 in die am Umfang des Messerkopfes 1 angeordneten, unter einem bestimmten Winkel gleich dem Anstellwinkel schräg eingefrästen Nuten eingelegt in der Weise, daß der Spannhebel 3 mit dem Rücken z. B. mittels eines Stiftes 4 (Abb. 3) oder ganz glatt am Fräskopf anliegt. Hierauf wird die Schraube 5 in den Spannhebel 3 eingeschraubt, bis sie am Stahl 2 zur Anlage kommt, um diesen in der Nut festzuklemmen, wird die Schraube 5 weitergedreht ; dadurch wird der kürzere Schenkel des Spannhebels 3 infolge der Drehung um seine Anlage am Fräskopf gegen den Stahl angepreßt. The steel 2 is with your clamping lever 3 in the arranged on the circumference of the cutter head 1, Grooves milled diagonally at a certain angle equal to the setting angle inserted in such a way that the clamping lever 3 with the back z. B. by means of a pen 4 (Fig. 3) or lies completely flat on the milling head. Then the screw 5 is in the clamping lever 3 screwed in until it comes to rest on steel 2 in order to clamp it in the groove, the screw 5 is turned further; this will make the shorter leg of the Clamping lever 3 pressed against the steel as a result of the rotation about its system on the milling head.
