Description
Zum Fräsen von Gewindeschneidbacfcen ist es üblich, den Backenhalter mittels Gewinde patrone während jeder Umdrehung: um: die Steigung des herzustellenden Gewindes vorzuschieben. Es war jedodh bisher erforderlich, die Gewindepatronen auszuwechseln, wenn Schneidbackengewinde verschiedener Steigung gefräst werden sollte. Gemäß der vorliegenden Erfindung besitzt die Patrone mehrere Gänge von verschiedener Steigung. Hierdurch wird der Fortschritt erzielt, daß mit der gleichen Patrone mehrere Schneidbackensätze mit Gewinde verschiedener Steigung gefräst werden können.For milling thread cutting bacfcen, it is common to use a thread cartridge to the jaw holder during each revolution: um: die Advance the pitch of the thread to be produced. However, it has hitherto been necessary replace the threaded cartridges if the die threads are different Slope should be milled. According to the present invention, the cartridge has several gears of different gradients. This achieves the progress that several sets of dies with threads of different pitch with the same cartridge can be milled.
In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt, und zwar sind in diesem Beispiel sechs Gewindegänge für ioer bis 15er Gangteilung angenommen, aber man kann die Gewindepatrone natürlich auch noch länger halten für noch mehr Gangverschiedenheiten.In the drawing, an example embodiment of the invention is shown, in this example there are six threads for 10 to 15 pitch accepted, but you can of course hold the threaded cartridge for longer even more gait differences.

An dem nicht dargestellten Lager des Backenhalters ist eine Platte m befestigt, die mit einem Längsschlitz m1 versehen ist. In diesem Schlitz lagert ein Finger I, der in ihm verstellt und durch eine Schraubenmutter« festgestellt wird. Der Finger I greift in einen der Patronengänge ein und schiebt den Schneidbackenhalter gemäß der betreffenden Steigung vor. In der Zeichnung steht der Finger beispielsweise in dem 14 Gänge ergebenden Gewindeteil. Wird eine andere Teilung gebraucht, so ist nur die Schraube η *° abzunehmen, der Finger im Schlitz m1 in den neuen Gang einzurücken und dann wieder festzuschrauben. A plate m , which is provided with a longitudinal slot m 1 , is attached to the bearing of the jaw holder (not shown). In this slot there is a finger I, which is adjusted in it and locked by a screw nut «. The finger I engages in one of the cartridge passages and advances the cutting jaw holder according to the relevant pitch. In the drawing, for example, the finger is in the thread part which results in 14 turns. If a different pitch is required, only the screw η * ° has to be removed, the finger inserted in the slot m 1 in the new gear and then screwed tight again.
