Description
Die Erfindung betrifft das Schleifen von Gewinden mittels Schleifscheiben mit mehreren in sich geschlossenen Rippen und unterscheidet sich von bekannten Verfahren dadurch, daß die relative Schrägstellung der Schleifscheibe nach Maßgabe der Gewindesteigung um eine zur Werkstückachse senkrechte Achse durch die "Spitze der letzten. Rippe-erfolgt, und daß die Schleif scheiben- »o rippen vor der letzten Rippe eine bestimmte Änderung der Rippenflankenlage erfahren, um einerseits die Annäherung der aufeinanderschleifenden Flanken durch die Schrägstellung des Werkzeuges zu beseitigen, andererseits die Arbeitsverfeilung auf die einzelnen Rippen zu regeln. Hierfür sind zwei verschiedene Möglichkeiten vorgesehen.The invention relates to the grinding of threads by means of grinding wheels with several self-contained ribs and differs from known processes in that that the relative inclination of the grinding wheel according to the thread pitch around an axis perpendicular to the workpiece axis through the "tip of the last. Rib-takes place, and that the grinding wheel- »O rib experience a certain change in the position of the rib flanks before the last rib on the one hand, the approach of the flanks rubbing against each other due to the inclination of the tool, on the other hand, the distribution of work on the individual To regulate ribs. There are two different ways of doing this.
In der Zeichnung ist das Verfahren gemäßIn the drawing the procedure is according to
der Erfindung schematisch beispielsweise dar-of the invention schematically, for example
ao gestellt, und zwar ist das Werkstück und Werkzeug in Abb. 1 so gezeigt, wie es von vorn gesehen wird.ao, namely the workpiece and Tool shown in Fig. 1 as seen from the front.
Hierbei liegt die Drehachse A-B des Werkstückes ι in der Waagerechten, wogegen die as Achse C-D der Schleifscheibe derart um die Achse O geschwenkt ist, daß die Profilrippen 3 der Schleifscheibe 2 im Steigungswinkel des zu schleifenden Gewindes verlaufen.The axis of rotation AB of the workpiece is horizontal, whereas the axis CD of the grinding wheel is pivoted about the axis O in such a way that the profile ribs 3 of the grinding wheel 2 run at the pitch angle of the thread to be ground.
Die Linien A-B und C-D schneiden die Achse O, die durch die Spitze der letzten Profilrippe 4 des Werkzeuges 2 geht.The lines AB and CD intersect the axis O, which goes through the tip of the last profile rib 4 of the tool 2.
Man kann das Werkstück 1 auch so verschwenken, daß seine Drehachse in Richtung der Linie A'-B' verläuft, die Drehachse der Schleifscheibe 2 muß dann in die Lage A-B gebracht werden.The workpiece 1 can also be pivoted so that its axis of rotation runs in the direction of the line A'-B ' ; the axis of rotation of the grinding wheel 2 must then be brought into position AB .
Ersichtlich liegt nur das die Fertigarbeit leistende Profil 4 theoretisch richtig zum Werkstück. Es müssen deshalb die Profile 3 der Scheibe, sofern auf eine genaue Gewindeerzeugung Wert gelegt wird, entweder schwächer gehalten werden als das normale Ringprofil 4, oder die Abstände der einzelnen Ringprofile müssen namentlich bei Gewinden mit größerem Steigungswinkel entsprechend der Schrägstellurig der Schleifscheibe, etwa von der vorletzten Rippe ausgehend, allmählich vergrößert werden.Obviously, only profile 4 doing the finishing work is theoretically correct for Workpiece. It must therefore be the profiles 3 of the disc, provided that an exact thread generation Emphasis is placed on either being kept weaker than the normal ring profile 4, or the distances between the individual Ring profiles must be used accordingly in the case of threads with a larger pitch angle the inclined position of the grinding wheel, starting approximately from the penultimate rib, gradually be enlarged.
In Abb. 2 ist punktiert angedeutet, wie die die Flanken S des Werkstückes bearbeitenden Flanken 6 der Schleifscheibe 2, wenn notwendig, verlegt werden können, und zwar bilden sie dann einen spitzeren Winkel auf der Spitzenebene wie das normale Profil.In Fig. 2 it is indicated by dotted lines how those machining the flanks S of the workpiece Flanks 6 of the grinding wheel 2, if necessary, can be laid, namely form they then make a more acute angle on the top plane like the normal profile.
Bei dieser Profilierung der Rippen wird in der Hauptsache eine Verspanung erreicht, wie sie in Abb. 3 schematisch dargestellt ist. Abb. 4 zeigt dagegen eine Schleifscheibe, bei der die Rillenabstände von Rippe zu Rippe wachsen. Der Abstand ist daher kleiner als der Abstand b. Bei dieser Ausbildung der Schleifscheibe wird eine Verspanung erreicht, wie sie in Abb. 5 schematisch dargestellt ist.With this profiling of the ribs, the main thing achieved is a bracing, as shown schematically in Fig. 3. In contrast, Fig. 4 shows a grinding wheel in which the groove spacing increases from rib to rib. The distance is therefore smaller than the distance b. With this design of the grinding wheel, a machining is achieved as shown schematically in Fig. 5.
