Description

Es ist bekannt, .daß Bohrstangen mit'mehreren Messern, welche zum gleichzeitigen Ausbohren mehrerer fluchtender Bohrungen dienen, auch selbst mehrfach gelagert werden müssen. - .It is known that boring bars with several Knives, which are used to drill several aligned holes at the same time serve, also have to be stored several times. -.

Ein Beispiel dafür ist das Bohren der Kurbelwellenlager und Nockenwellenlager an Motorgehäusen, bei denen die Bohrstange durch mehrere Zwischenlager gestützt werden muß.An example of this is drilling the crankshaft bearings and camshaft bearings on Motor housings in which the boring bar is supported by several intermediate bearings got to.

Das Einschieben und Herausziehen der Bohrstange erfordert jedoch an den Lagern besondere Einrichtungen, um die feststehenden Bohrmesser hindurchzubekommen. Dadxirch wird die Vorrichtung verteuert, und oft leidet auch die Genauigkeit der fertigen Arbeit. However, pushing in and pulling out the boring bar requires on the bearings special facilities to get the fixed boring knives through. Dadxirch the device becomes more expensive and the accuracy of the finished work often also suffers.

Eine Verbesserung tritt durch die Verwendung von Ringkörpern ein, die auf die Bohrstange aufgesetzt werden können und die einstellbaren Bohrmesser in radialer oder tangentialer Anordnung tragen. Ihre Befestigung auf der Bohrstange erfolgt zumeist durch Klemmung, beispielsweise durch ein sog. Federgelenk, das durch eine Klemmschraube zusammengepreßt wird. Um diese Ringkörper von der Bohrstange abziehen zu können, ist es notwendig, nach Lockerung der Klemmung die Bohrstange . aus ihren sämtlichen Lagern herauszuziehen. Der Messerring gemäß der Erfindung gestattet dagegen jederzeit ein leichtes Aufsetzen und Abnehmen von der Bohrstange, ohne dieselbe aus ihnen Lagern entfernen zu müssen. Er besteht aus zwei Schellen, die durch ein Gelenkstück klappbar verbunden sind und sich mittels Schraube auf der Bohrstange festklemmen lassen. Der Messerring trägt das Bohrmesser, welches vor dem Aufsetzen des Ringes zweckmäßig auf einer besonderen Vorrichtung genau auf das fertige Bohrmaß eingestellt worden ist. An sich sind aus zwei Schellen bestehende Ringe, die durch ein Gelenkstück klappbar verbunden sind und sich mittels Schraube o. dgl. auf einer Bohrstange "festlegen lassen, bekannt, doch nicht als Werkzeugträger, sondern als Vors chub ringe.An improvement occurs through the use of ring bodies that attach to the drill rod can be placed and the adjustable drill knives in radial or tangential Wear arrangement. They are mostly attached to the boring bar by clamping, for example by a so-called spring hinge, that by a clamping screw is compressed. To pull this ring body from the boring bar too it is necessary to remove the boring bar after loosening the clamping. from their pull out all bearings. The knife ring according to the invention allows against it Easy to put on and remove from the boring bar at any time without having to remove the same from their bearings. He consists of two clamps, which are hingedly connected by a joint piece and which are themselves can be clamped with the screw on the boring bar. The knife ring carries the drill knife, which before putting the ring on a special device has been set exactly to the finished drilling dimension. In itself, rings are made up of two clamps, which are connected by a joint Are hingedly connected and by means of a screw or the like. On a boring bar "Let it be defined, known, but not as a tool holder, but as a feed ring.

Um den Innendurchmesser des neuen Messerringes zur Verwendung möglichst starker Biolirwelleii recht groß halten zu können, ist das verstellbare Bohrmesser tangential angeordnet. To use the inner diameter of the new knife ring as strong as possible Being able to keep Biolirwelleii quite large is the adjustable drill knife arranged tangentially.

Auf der Zeichnung ist der Erfmdungsgegenstand dargestellt, und zwar zeigt Fig. 1 die Bohrstange 1, in den beiden festen Gleitlagern 2 und 3 gelagert, um die Bohrung des Werkstückes 4 zu bearbeiten. Fig. 2 zeigt den aufgesetzten Messerring 5 in der Seitenansicht. Letzterer ist in Fig. 3 nochmals im Schnitt veranschaulicht.The subject of the invention is shown in the drawing, namely FIG. 1 the boring bar 1, mounted in the two fixed slide bearings 2 and 3 to drill the Workpiece 4 to be machined. Fig. 2 shows the attached knife ring 5 in a side view. The latter is illustrated again in section in FIG. 3.

Er besteht aus den zwei Schellen 6 und 7, die durch das Gelenk 8 und die Klemmschraube 9 auf die Bohrstange 1 geklemmt werden. In^der Schelle 7 sitzt tangential das Bohrmesser io; es wird durch seitliche Klemmschrauben 11 und 12 gehalten.It consists of the two clamps 6 and 7, which are connected by the joint 8 and the clamping screw 9 can be clamped onto the boring bar 1. In ^ the clamp 7 sits tangentially Drill knife io; it is made by clamping screws on the side 11 and 12 held.
