Description

Gegenstand des Hauptpatents ist eine Vorrichtung zur Ausführung von Plan- bzw. Formbohrarbeiten auf Feinbohrmaschinen mit in dem Kopf der Bohrspindel in einer Radialführung verschiebbar gelagertem, das Bohrwerkzeug tragendem Schlitten, der mit einem Stahlband verbunden ist, das über im Innern des Bohrkopfes gelagerte Rollen geführt ist und dessen eines Ende nachgiebig unter Federwirkung verschiebbar in der Bohrspindel gelagert ist, während sein anderes Ende an einer im Innern der Bohrspindel . längs verschieblich gelagerten, von außen verstellbaren Stange befestigt ist. Bei derartigen . 1S Bohrvorrichtungen ist die Genauigkeit der Arbeit zu einem gewissen Ausmaß dadurch beeinträchtigt, daß der radial verstellbare Schlitten, der das Werkzeug trägt, infolge seiner exzentrischen Lage zu Schwingungen Veranlassung gibt. Diese Schwierigkeiten werden gemäß der Erfindung in einfacher und zuverlässiger Weise dadurch überwunden, daß die Führungsrollen des Stahlbandes zum Zwecke des Massenausgleichs auf ihrer der Ausschlagsrichtung des Werkzeugschlittens entgegengesetzten Seite durch Bleiausguß ο. dgl. beschwert bzw. auf ihrer dem Werkzeugschlitten zugewandten Seite durch entsprechende Bohrungen erleichtert sind.The subject of the main patent is a device for performing face or form boring work on precision boring machines with a slide bearing the drilling tool, which is slidably mounted in a radial guide in the head of the drilling spindle and which is connected to a steel band that is guided over rollers mounted inside the drilling head and one end of which is supported resiliently displaceably under the action of a spring in the drilling spindle, while its other end is mounted on one in the interior of the drilling spindle. longitudinally displaceable, externally adjustable rod is attached. With such. 1 S drilling devices, the accuracy of the work is impaired to a certain extent by the fact that the radially adjustable slide that carries the tool causes vibrations due to its eccentric position. According to the invention, these difficulties are overcome in a simple and reliable manner in that the guide rollers of the steel belt for the purpose of balancing the masses on their side opposite the direction of deflection of the tool slide are poured with lead ο. Like. Weighted or are facilitated on their side facing the tool slide by appropriate holes.

Auf diese Weise gelingt es, eine von der Stellung des Werkzeugsc'hlittens vollkommen unabhängige Auswuchtung des Bohrstangenkopfes zu erzielen und hierdurch die Ursache von Schwingungen und Bearbeitungsungenauigkeiten weitestgehend zu beseitigen.In this way it is possible to completely adjust the position of the tool holder to achieve independent balancing of the boring bar head and thereby the cause to eliminate vibrations and machining inaccuracies as far as possible.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes im Schnitt.The drawing illustrates an embodiment of the subject matter of the invention on average.

Der Bohrspindelkopf 3 ist mit einer radialen Führungsnut 4 versehen, in der der das Werkzeug ι tragende Schlitten 2 verschiebbar gelagert ist. Die Bewegung des Schlittens wird gemäß Patent 661 714 über das Stahlbands bewirkt, das über vier Führungsrollen.6 läuft. Diese tragen auf der der Aus-Schlagsrichtung des Werkzeugschlittens 2 abgewandten Seite je einen durch Doppelschraffur angedeuteten Bleiausguß ο. dgl. 22 'bzw', "auf der entgegengesetzten Seite eine entsprechend angeordnete Bohrung. Die Massenverteilung läßt sich hierbei so wählen, daß die Bohrspindel 3 bei jeder Stellung des Werkzeugschlittens 2 vollkommen ausgewuchtet ist.The drilling spindle head 3 is provided with a radial guide groove 4 in which the Tool ι bearing carriage 2 is slidably mounted. The movement of the sled is effected according to patent 661 714 via the steel belt, which has four guide rollers. 6 runs. These bear on the deflection direction of the tool slide 2 facing away Side a lead pouring indicated by double hatching ο. like 22 'or', "on the opposite side a correspondingly arranged hole. The Mass distribution can be chosen so that the drill spindle 3 in every position of the Tool slide 2 is completely balanced.
