Description

Schleifen von Gewinden Beim Schleifen von Gewinden ist es bekannt, Schleifkonen mit mehreren nebeneinanderliegenden, in sich geschlossenen Rillen Lind Rippen zu verwenden, die nacheinander den Werkstoff verspanen.Grinding of threads When grinding threads, it is known Grinding cones with several adjacent, self-contained grooves Lind To use ribs that machine the material one after the other.

Dieses Arbeitsverfahren hat jedoch den Nachteil, .daß zum Abrichten solcher Schleifkonen auch konische A@brichtrollkörper benutzt werden müssen, da sonst Verzerrungen des Profils eintreten würden, die ein einwandfreies Gewinde nicht erreichen lassen.However, this working method has the disadvantage, that for dressing Such grinding cones also have to be used with conical breaking rollers because otherwise the profile would be distorted, which would not make a perfect thread let reach.

Konische Abrichtwerkzeuge verschleißen sich aber sehr schnell und müssen infolgedessen sehr häufig nachgeschliffen werden.Conical dressing tools wear out very quickly and consequently have to be sharpened very frequently.

Dies ist auf die verschiedenen Umlaufgeschwindigkeiten der einzelnen im Durchmesser unterschiedlichen Profilringe des Abrichtkörpers zurückzuführen, wodurch ein Mahlen zwischen Abrichtkörper und Schleifkonus eintritt.This is due to the various rotational speeds of each due to different diameter profile rings of the dressing body, whereby grinding occurs between the dressing body and the grinding cone.

Dieser Nachteil soll gemäß der Erfindung dadurch beseitigt werden, daß der aus mehreren in sich geschlossenen Rippen und Rillen bestehende Schleifzylinder mit einer Drehachse so zur Werkstückachse geneigt ist, daß, wie bei den bekannten mehrrill;igen Schleifkonen, die Verspanung auf die einzelnen Profile verteilt ist und das Profil jeder Schleifrippe auf dem schrägen Zylinder zur Erzeugung symmetrischer Gewindeprofile so urisymmetrisch ausgebildet ist, daß die die Profile halbierende Linie senkrecht zur Werkstückachse steht.According to the invention, this disadvantage is to be eliminated by that the grinding cylinder consisting of several self-contained ribs and grooves is inclined with an axis of rotation to the workpiece axis that, as in the known multi-groove grinding cones, the chipping is distributed over the individual profiles and the profile of each grinding rib on the inclined cylinder to create more symmetrical ones The thread profile is so urisymmetrical that the bisecting the profile Line is perpendicular to the workpiece axis.

In :der Zeichnung ist die Erfindung an Hand eines Schemas beispielsweise veranschaulicht, und zwar liegt die Werkstückachse II-II winklig zur Werkzeugachse I-I, was sowohl durch Verdrehen des Schleifspindelsupportes als auch durch Verschwenken des Werkstückes i in der waagerechten Ebene erreicht wenden kann.In: the drawing, the invention is exemplified on the basis of a scheme illustrated, namely the workpiece axis II-II is at an angle to the tool axis I-I, both by turning the grinding spindle support and by swiveling it of the workpiece i can be reached in the horizontal plane.

Um die Profile auf dem Schleifzylinder 2 zu erzeugen, bedient man sich eines zylindrischen Abrichtkörpers 3, dessen Achse III-III parallel zur Schleifscheibenachse 1-I liegt. Die Profile des Abr ichtkörpers 3 sind jedoch nicht normal, sondern die eine Flanke ist etwas länger als die andere Flanke jeden Profils. Dadurch ergeben sich dann auch auf der Schleifscheibe Profile, bei denen die Flanke d. länger ist als die Flanke 5, und zwar steht .die die Profile 6 halbierende Mittellinie IV-IV senkrecht zur Achse II-11 des Werkstückes i, dagegen winklig zur Achse 1-I des Schleifzylinders 2.In order to generate the profiles on the grinding cylinder 2, one operates a cylindrical dressing body 3, the axis III-III of which is parallel to the grinding wheel axis 1-I lies. However, the profiles of the dressing body 3 are not normal, but the one flank is slightly longer than the other flank of each profile. Result from this Then there are also profiles on the grinding wheel in which the flank d. is longer than the flank 5, namely .the profile 6 bisecting the center line IV-IV perpendicular to the axis II-11 of the workpiece i, but at an angle to the axis 1-I of the grinding cylinder 2.

Auf diese Weise ist es möglich, Gewinde vorteilhaft zu schleifen, ohne die Nachteile der Schleifkonen in Kauf nehmen zu müssen.In this way it is possible to grind threads advantageously, without having to accept the disadvantages of the grinding cones.

PATENTANSPRUCH: Schleifen von Gewinden mittels eines aus mehreren in sich geschlossenen Rippen und Rillen bestehenden (mehrprofiligen) Schleifzylinders, dadurch gekennzeichnet, daß der Schleifzylinder mit seiner Drehachse so zur Werkstückachse geneigt ist, daß, wie bei den bekannten mehrrilligen Schleifkonen, die Verspannung auf die einzelnen Profile verteilt ist, und daß das Profil jeder Schleifrippe auf dem schrägen Zylinder zur Erzeugung symmetrischer Gewindeprofile so unsyminetrisch ausgebildet ist, daß die die Profile (6) halbierende Linie (IV-IV) senkrecht zur Werkstückachse (II-11) steht. PATENT CLAIM: Grinding of threads by means of a (multi-profile) grinding cylinder consisting of several self-contained ribs and grooves, characterized in that the axis of rotation of the grinding cylinder is inclined to the workpiece axis in such a way that, as with the known multi-groove grinding cones, the tension on the individual Profiles is distributed, and that the profile of each grinding rib on the inclined cylinder for generating symmetrical thread profiles is so asymmetrical that the line (IV-IV) bisecting the profiles (6) is perpendicular to the workpiece axis (II-11).
