Description
Das Gewindeschneidwerkzeug gemäß der Erfindung hat verstellbare Gewindesohneidbacken, die gezogen werden, also mit ziehendem Schnitt arbeiten und demnach ein sehr glattes Gewinde schneiden.The thread cutting tool according to the invention has adjustable thread buttocks, that are pulled, so work with a pulling cut and therefore a very cut a smooth thread.
Auf der Zeichnung ist eine Ausführungsform für Innengewinde eines derartigen Gewindeschneidwerkzeuges in Abb. ι teilweise im Längsschnitt, teilweise in Ansicht und in ίο Abb. 2 im Querschnitt veranschaulicht.The drawing shows an embodiment for internal threads of such a thread cutting tool in Fig. ι partly in longitudinal section, partly in view and in ίο Fig. 2 illustrated in cross section.
Die Drehzapfen α der die Gewindeschneidbacken δ tragenden Hebel d halten diese in einer Kreisnut/ am Werkzeugkörperg, in dem durch Federn h gestützte Hülsen t angeordnet sind, die sich gegen die vorderen Enden der Hebel d legen. Dadurch werden diese gegen keilförmige Anschlaget gedrückt, die vor den Schneidkanten der Schneidbacken angeordnet sind. Diese Anschläge sind in dem Körper g achsial verschiebbar gelagert und mit einem Ring k verbunden, der auf eine Gewindebüchse m geschraubt ist, die drehbar auf dem Hals η des Werkzeüigkörpers angeordnet ist. Der Rand der Büchse m trägt eine Maßeinteilung, und gegen ihn legt sich ein Ring ο mit Marken für die verschiedenen Gewindedurchmesser. Mittels einer Schraube/» kann dieser Ring ο in jeder Lage auf dem Hals η festgestellt werden. Ein aufge·; schraubter Ring sichert den Ring ο gegen achsiale Verschiebungen.The pivot pins α of the lever d carrying the thread cutting jaws δ hold them in a circular groove / on the tool body g, in which sleeves t supported by springs h are arranged, which lie against the front ends of the lever d. As a result, they are pressed against wedge-shaped stops, which are arranged in front of the cutting edges of the cutting jaws. These stops are mounted in the body axially displaceable and g k connected to a ring which is screwed onto a threaded bush m rotatably η on the neck of Werkzeüigkörpers is arranged. The edge of the box m carries a scale and against him a ring sets ο with brands for the different thread diameter. This ring ο can be fixed in any position on the neck η by means of a screw / ». An up ·; The screwed ring secures the ring ο against axial displacement.
Durch Drehen des Ringes ο werden die Anschläge i und damit die Schneidbacken verstellt. Die Maßeinteilung zeigt die genaueBy turning the ring ο , the stops i and thus the cutting jaws are adjusted. The graduation shows the exact
Einstellung der Messer an. Auch das An- und Abstellen der Schneidbacken wird auf diese Weise vorgenommen.Setting the knives on. The cutting jaws are also switched on and off done this way.
