Description
in Wahren-Leipzig.in Wahren-Leipzig.
Um den zu schneidenden Gewindedurchmesser bei Schneidköpfen genau einstellen zu können, ist ein Verdrehen des Vorderteiles des Schneidkopfes gegenüber dem Schaftkörper nötig. Diese Verdrehung wird durch eine Einstellschraube bewirkt, die im Schaftkörper angeordnet ist und sich gegen eine die Bewegung weiterleitende Büchse legt.In order to precisely set the thread diameter to be cut on cutting heads is a twisting of the front part of the cutting head with respect to the shaft body necessary. This rotation is caused by an adjusting screw in the shaft body is arranged and lays itself against a sleeve which transmits the movement.
Die Einstellschraube wurde bisher entweder ίο im Schaftkörper selbst oder in einer im Schaftkörper gelagerten Hülse geführt und durch eine Gegenmutter festgehalten. Diese löste sich aber trotz festen Anziehens infolge ihrer durch die Bauart des Schneidkopfes bedingten kleinen Reibfläche durch die Erschütterungen1 der Maschine leicht, was ein Verdrehen der Einstellschraube und dadurch eine Veränderung des Schraubendurchmessers hervorrief. Die Erfindung verhütet diesen Übelstand, und zwar dadurch, daß die die Einstellschraube tragende Hülse geschlitzt und an ihrem hinteren Ende kegelförmig angedreht ist, so daß durch Aufschrauben einer kegelförmig ausgedrehten Gegenmutter die geschlitzte Hülse zusammengepreßt wird. Dadurch wird die Einstellschraube festgehalten. Die Gewindeteile der Hülse werden dabei in das Gewinde der Einstellschraube weiter hineingedrückt. 'The adjusting screw was previously either guided in the shaft body itself or in a sleeve mounted in the shaft body and held in place by a lock nut. However, this loosened easily despite the firm tightening due to its small friction surface caused by the design of the cutting head due to the vibrations 1 of the machine, which caused the adjustment screw to rotate and the screw diameter to change. The invention prevents this inconvenience in that the sleeve carrying the adjusting screw is slotted and screwed conically at its rear end so that the slotted sleeve is compressed by screwing on a counter nut that has been screwed out conically. This will hold the adjusting screw in place. The threaded parts of the sleeve are pressed further into the thread of the adjusting screw. '
Die Zeichnung stellt einen Schneidkopf mit der Erfindung dar, und zwar zeigen Abb. 1 eine Vorderansicht und Abb. 2 eine Seitenansicht. The drawing shows a cutting head with the invention, namely Fig. 1 a front view and Fig. 2 is a side view.
α ist das Vorderteil, b der Schaftkörper des Schneidkopfes. In dem Schaftkörper befindet sich die bei d geschlitzte Hülse c, die beispielsweise durch einen Stift e gegen Verschiebung und Drehung geschützt ist. Die Hülse ist an ihrem aus dem Kopf ragenden Ende abgeschrägt. In dieser Hülse befindet sich die Einstellschraube f, die sich gegen die Büchse glegt. Auf der Einstellschraube befindet sich die Gegenmutter h. Die Gegenmutter h ist entsprechend der Schräge der Hülse c ausgearbeitet. α is the front part, b the shaft body of the cutting head. The sleeve c, which is slit at d and is protected against displacement and rotation, for example by a pin e, is located in the shaft body. The sleeve is beveled at its end protruding from the head. In this sleeve there is the adjusting screw f, which is placed against the bush. The lock nut h is on the adjusting screw. The lock nut h is worked out according to the slope of the sleeve c .
