Description

Die Erfindung bezieht sich auf Bohrwerkzeuge, z. B. Spi.ralbohmer, mixt konischem Schaft und einen auf diesem Schaft angeordneten Ansatz, den- als Anschlag für einen drehbaren Abdrückring dient, welcher auf dem .den Bohrer .aufnehmenden Teil, z. B. auf einer Reduzierhülse, angebracht ist.The invention relates to drilling tools, e.g. B. Spi.ralbohmer, mixes a conical shaft and a shoulder arranged on this shaft, called The stop for a rotatable forcing ring is used, which is placed on the .the drill Part, e.g. B. on a reducing sleeve is attached.

Reduzierhülsen, mit auf ihnen versahraubbarer Lösemutter zum Auswerfen vom, Werkzeugen mit konischem Schaft, auf dem. ein Ring .mit konischer Bohrung aufgesteckt wird, sind bereits bekannt.Reducing sleeves with releasing nut that can be moved onto them for ejection vom, tools with a conical shaft on which. a ring with a conical bore attached are already known.

Die Erfindung besteht nun darin, daß der Anschlag für den drehbaren Abdrückring mit Mitnehmerwarzen versehen ist, die in Einschnitte des vorderen Endes des den Bohrer aufnehmenden Teiles, z. B. einer Reduzierhülse, eingreifen. Diese Mitnehmerwarzen haben die Aufgabe, ein Verdrehen des Bohrwerkzeugs in, der Hülse zu verhindern.The invention consists in that the stop for the rotatable Forcing ring is provided with driving lugs, which are cut into the front end of the part receiving the drill, e.g. B. a reducing sleeve, engage. These Driving lugs have the task of twisting the drilling tool in the sleeve to prevent.

In Fig. i der Zeichnung ist ein Bohrer darge@ stellt, dessen konischer Schaft i @am Schaftende einem mit dem Schaft fest verbundenen Ansatz 2 besitzt. Der Ansiatz ist so ausgebildet, daB er, sowohl als Anschlag für eine auf einer Reduzierhül,se 3 verschraubbare Abdrückringmutter4 (Fig.2) dient, als auch als Mitnehmer für den in die eingesetzten Bohrer. (Fig. 3).In Fig. I of the drawing a drill is Darge @ presents, its conical Shank i @ the end of the shank has a shoulder 2 firmly connected to the shank. The approach is designed in such a way that it can be used as a stop for a reducing sleeve 3 screwable forcing ring nut4 (Fig. 2) serves as a driver for the into the inserted drill. (Fig. 3).

Der Ansatz 2 besitzt deshalb eine Anschlagfläche 5, auf welche die AbdrückringmutteT 4 beim Niederschrauben drückt; hierdurch wird der Bohrer aus der Hülse entfernt. Ferner besitzt der Ansatz M.itnehmerwarzen 6. Diese kommen. beim Einsetzen des Bohrers in die Reduzierhülse in deren entsprechend ausglebilderte sti.rn:seitige Aussparungen 7 zu liegen, so daB eine sichere Mitnahme des Bohxler.s gewährleistet und ein. Rutschen des Werkzeuges in der Hülse vermieden wird. Durch Hochschrauben der Ringmutter 4 wird das Läsen der Reduzierhülse aus. der Bohrspindel ermöglicht.The approach 2 therefore has a stop surface 5 on which the Forcing ring nut T 4 presses when screwing down; this will remove the drill from the Sleeve removed. Furthermore, the approach has m. Driver warts 6. These come. at the Insertion of the drill into the reducing sleeve in its correspondingly designed sti.rn: side recesses 7 to lie, so that the Bohxler.s guaranteed and a. Slipping of the tool in the sleeve is avoided. By Screwing up the ring nut 4 will stop the reducing sleeve from loosening. the drilling spindle enables.
