Description
Die Erfindung bezieht sich auf eine Tieflochbohrmaschine zur Bearbeitung metallischer Werkstücke, deren an einem Ende mit einer Bohrkrone versehenes, antreibbares Bohrrohr gegenüber einer drehbar gelagerten, auswechselbaren, dem Bohrdurchmesser entsprechenden Bohrbuchse axial verschiebbar und durch ein längs eines Rohres geführtes Kühlmittel beaufschlagbar ist, welches anfallende Späne durch den Rohrinnenraum abführt.The invention relates to a deep hole drilling machine for machining metallic workpieces, whose drivable drill pipe is provided with a drill bit at one end and can be rotated relative to one mounted, replaceable, drill bushing corresponding to the drilling diameter and axially displaceable can be acted upon by a coolant which is guided along a pipe and through which chips are deposited discharges the pipe interior.
Bei derartigen Tieflochbohrmaschinen treten Schwingungen, insbesondere Torsionsschwingungen auf, die sich bei größeren Bohrtiefen bis zur Bohrkrone fortsetzen und deren Standzeit herabsetzen.In deep hole drilling machines of this type, vibrations occur, in particular torsional vibrations which continue to the drill bit at greater drilling depths and reduce their service life.
Der Erfindung liegt die Aufgabe zugrunde, Torsionsschwingungen des Bohrrohres zu vermeiden und dadurch die Relativbewegung zwischen Bohrrohr und Bohrbuchse gering zu halten.The invention is based on the object of avoiding torsional vibrations of the drill pipe and thereby keeping the relative movement between the drill pipe and the drill bushing low.
Die Lösung der Aufgabe besteht erfindungsgemäß darin, daß die Bohrbuchse über einen in einem maschinenfest angeordneten Gehäuse drehbar gelagerten, mit einer Schwungmasse versehenen Ringkörper und eine einstellbare Klemmbuchse mit dem Bohrrohr verbunden ist.According to the invention, the object is achieved in that the drill bushing is fixed to the machine via one in one arranged housing rotatably mounted, provided with a flywheel ring body and an adjustable collet is connected to the drill pipe.
Durch die Erfindung wird der technische Fortschritt erzielt, daß beim Umlaufen der Bohrbuchse mit dem sich drehenden Bohrrohr der Verschleiß der Bohrbuchse und der Bohrkrone auf ein Minu reduziert wird, weil zwischen der Bohrkrone und der Bohrbuchse keine Drehbewegungen mehr auftreten. Ein Verschleiß kann also nur dadurch auftreten, daß die Bohrkrone in der Bohrbuchse axial verschiebbar ist. Da nun die Bohrbuchse über den Ringkörper und die Klemmbuchse mit einer Schwungmasse verbunden ist, dämpft die Schwungmasse auftretende Schwingungen, insbesondere Torsionsschwingungen, und zwar deswegen besonders gut, weil die Schwungmasse immer mit gleichem Abstand von der Bohrbuchse angeordnet ist, ihre Lage also unabhängig von der Bohrlänge ist.The invention achieves technical progress that when rotating the drill bushing With the rotating drill pipe, wear on the drill bushing and the drill bit is reduced to a minimum because no more rotary movements occur between the drill bit and the drill bushing. Wear can only occur because the drill bit is axially displaceable in the drill bushing is. Since now the drill bushing is connected to a flywheel via the ring body and the clamping bushing the flywheel dampens vibrations, especially torsional vibrations, especially good because the flywheel is always at the same distance from the drill bushing is arranged, so its position is independent of the drilling length.
Die Erfindung wird an Hand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles nachstehend erläutert.The invention is based on an exemplary embodiment shown schematically in the drawing explained below.
Es zeigt die Figur einen Querschnitt durch den Teil der Tieflochbohrmaschine, der die Bohrbuchse enthält.It shows the figure a cross section through the part of the deep hole drilling machine, which the drill bushing contains.
In einem maschinenfest angeordneten Gehäuse 1. das mittels einer Lünette 4 festlegbai ist, ist über nachstellbare Kegelrollenlager 7 ein Ringkörper 9 gelagert. Zwischen den beiden Kegelrollenlagern 7 ist ein Kühlmittelzufuhrring 5 abgedichtet angeordnet. Der Ringkörper 9 umfaßt die Bohrbuchse 3, beide Teile sind gegeneinander festgelegt, beispielsweise über ein Gewinde, so daß sie eine starre Einheit bilden. Zwischen der Bohrbuchse 3 und dem Bohrrohr 2 befindet sich ein Ringraum 12, so daß über das Gehäuse 1 und den Kühlmittelzufuhrring 5, den Ringkörper 9 ein Kühlmittel K1 durch den Ringraum 12 zur nicht dargestellten Bohrkrone geleitet werden kann. Dieses Kühlmittel K1 wird also zwischen der Außenfläche des Bohrrohres 2 und der durch die Bohrkrone erzeugten Bohrung 13 im Werkstück 14 bewegt. Da sowohl das Werkstück 14 als auch die mit einem Dichtring 6' versehene Abdeckscheibe nicht umlaufen, bereitet das Abdichten keinerlei Schwierigkeiten. Es ist nicht unbedingt notwendig, daß ein Dichtring 6' vorgesehen ist.In a machine-fixed housing 1, which can be fixed by means of a steady rest 4, an annular body 9 is mounted via adjustable tapered roller bearings 7. A coolant supply ring 5 is arranged in a sealed manner between the two tapered roller bearings 7. The ring body 9 comprises the drill bushing 3, both parts are fixed against one another, for example by means of a thread, so that they form a rigid unit. Between the drill bushing 3 and the drill pipe 2 there is an annular space 12 so that a coolant K 1 can be passed through the annular space 12 to the drill bit, not shown, via the housing 1 and the coolant supply ring 5, the annular body 9. This coolant K 1 is therefore moved between the outer surface of the drill pipe 2 and the bore 13 in the workpiece 14 produced by the drill bit. Since neither the workpiece 14 nor the cover disk provided with a sealing ring 6 'do not run around, the sealing does not cause any difficulties. It is not absolutely necessary for a sealing ring 6 'to be provided.
Mit dem Ringkörper 9 ist über eine Klemmbuchse 10 eine Schwungmasse 8 kuppelbar. Eine Nachstellmutter 11 mit Außengewinde gestattet das Einstellen des Klemmdruckes, der so zu wählen ist, daß die Schwungmasse 8, läuft das Bohrrohr 2 um, mitgenommen wird, trotzdem aber ein axiales Verschieben des Bohrrohres 2 möglich ist. Das Kühlmittel Kx gelangt über die Bohrkrone in den Innenraum 15 des Bohrrohres 2 wie durch Pfeile angedeutet.A flywheel 8 can be coupled to the ring body 9 via a clamping sleeve 10. An adjusting nut 11 with an external thread allows the clamping pressure to be set so that the centrifugal mass 8 is carried along when the drill pipe 2 rotates, but an axial displacement of the drill pipe 2 is still possible. The coolant K x reaches the interior 15 of the drill pipe 2 via the drill bit, as indicated by arrows.
