Description

Die Reibahle gemäß dem Patent 323267 soll an Stelle der früher starr angeordneten Messer federnd schleppende Messer haben.The reamer according to patent 323267 is intended to replace the previously rigid one Knives have resilient dragging knives.

Durch Versuche ist festgestellt worden, daß auch bewegliche, starr gestützte Messer einen gleichwertigen Schnitt erzeugen.Experiments have shown that movable, rigidly supported knives are also one create an equivalent cut.

Auf der Zeichnung ist eine Ausführungsform einer derartigen Reibahle in Abb. 1 teilweise im Längsschnitt, teilweise in Ansicht und in Abb. 2 im Querschnitt veranschaulicht.In the drawing, an embodiment of such a reamer in Fig. 1 is partially illustrated in longitudinal section, partially in elevation and in Fig. 2 in cross section.

Die die Messer b tragenden Stahlhalter d The steel holders d carrying the knives b

sind in einer Ringnut f des Reibahlenkörpers g um die Bolzen α schwingbar angeordnet.are arranged in an annular groove f of the reamer body g to swing around the bolts α .

Gegen die vorderen Enden der Stahlhalter d legen sich Hülsen t, die unter der Wirkung von Federn h stehen; durch diese Federn werden die Stahlhalter gegen keilförmige Anschläge i gedrückt. Diese Anschläge i sind in dem Reibahlenkörper g achsial verschiebbar gelagert und mit einem Ring k verbunden, der auf eine Gewindebüchse m geschraubt ist, die drehbar auf dem Hals η des Reibahlenkörpers angeordnet ist. Der Rand der Büchse m trägt eine Strichteilung, und gegen ihn legt sich ein Ring 0 mit Marken für die verschiedenen Passungen. Mittels einer Schraube β kann dieser Ring 0 in jeder Lage auf dem Hals η festgestellt -werden. Eine Ringmutter r sichert den Ring 0 gegen achsiale Verschiebungen. Sleeves t, which are under the action of springs h , lie against the front ends of the steel holders d; These springs press the steel holders against wedge-shaped stops i. These stops are i in which g Reibahlenkörper axially displaceably mounted and connected with a ring k screwed m on a threaded bush which rotatably η on the neck of Reibahlenkörpers is arranged. The edge of the sleeve m has a line division, and against it lies a ring 0 with marks for the various fits. This ring 0 can be fixed in any position on the neck η by means of a screw β. A ring nut r secures the ring 0 against axial displacement.

Durch Drehen der Büchse m werden die Anschläge i und damit die Messer verstellt. Die Strichteilung zeigt die genaue Einstellung der Messer an. Auch das An- und Abstellen der Messer wird auf diese Weise vorgenommen.By turning the sleeve m , the stops i and thus the knives are adjusted. The graduation shows the exact setting of the knives. The knives are also switched on and off in this way.
