Description
Die bekannten Reibahlen haben fast alle den Fehler, daß der Benutzer während des Ausreibens von Bohrlöchern das Werkzeug , leicht so schief halten kann, daß es zerbricht. The known reamers almost all have the problem that the user reams them out of drill holes the tool can easily hold so crooked that it breaks.
Durch die vorliegende Erfindung soll dieser Mangel, der besonders bei der Ausreibung in bestimmter Entfernung voneinander liegender Bohrlöcher stört, vermieden ίο ■ werden.The present invention is intended to address this deficiency, which is particularly evident in the case of the boreholes lying at a certain distance from one another disturbs, ίο ■ be avoided.
Es geschieht dies durch eine aus einer Mutter bestehende Zentriervorrichtung, die auf den hinteren schraubenförmigen Teil der Reibahle aufgeschraubt ist und außen einen Kegel von solcher Form und Größe besitzt, daß er sich von selbst einem der Löcher anpaßt.This is done by a centering device consisting of a nut, which is screwed onto the rear helical part of the reamer and on the outside one Cones of such shape and size that they fit one of the holes by themselves adapts.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung, und zwar von der Seite gesehen, dargestellt.In the drawing is an embodiment of the invention, from the side seen, shown.
Die Reibahle 1 hat außer den Schneiden 2 am entgegengesetzten Ende einen schraubenförmigen Teil 3, der in unmittelbarer Nähe des Zapfens 4 liegt, auf den der zum DrehenIn addition to the cutting edges 2, the reamer 1 has a helical one at the opposite end Part 3, which is in the immediate vicinity of the pin 4, on which to rotate
der Reibahle dienende Handgriff 5 aufge- 25 steckt wird.the handle 5 serving the reamer is attached.
Auf den schraubenförmigen Teil 3 ist eine auswendig kegelige Mutter. 6 mit einem Flansch 7 aufgeschraubt.On the helical part 3 is an internally conical nut. 6 with one Flange 7 screwed on.
Die kegelige Außenfläche der Mutter hat die Aufgabe, die Reibahle in einem der Bohrlöcher zu zentrieren, während die Schneiden in den anderen Bohrlöchern arbeiten. Ferner soll die Mutter auch eine Unterstützung des hinteren Teiles der Reibahle bilden, so daß die Gefahr des Zerbrechens geringer ist.The tapered outer surface of the nut has the task of holding the reamer in one of the drill holes to center while the cutting edges work in the other drill holes. Further the mother should also form a support for the rear part of the reamer, so that the risk of breakage is lower.
