Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Festklemmen des Drehmantels von Radialbohrmaschinen.The invention relates to a device for clamping the Rotary casing of radial drilling machines.
Es sind bereits Klemmvorrichtungen in Form von Keilen für den Drehmantel von Radialbohrmaschinen bekannt, die den Durchhang von Radialhohrmasch.inen vermeiden sollen. Diese Keile lassen sich jedoch nicht gleichzeitig gleichmäßig anziehen. Zur Vermeidung dieses Nachteiles hat man schon einen Spannring benutzt. Durch Drehen dieses mit schrägen Flächen versehenen Ringes werden die einzelnen Klemmkeile angezogen. Hierdurch ergibt sich jedoch der Nachteil, daß die Keile bei jeder Drehung des Spannringes nur einen bestimmten Weg zurücklegen. Ist jedoch die Stellung der zu verklemmenden Teile nicht genau konzentrisch, was bei den tatsächlichen Verhältnissen immer der Fall sein wird, so müssen die Keile mit einem unterschiedlichen Weg bis zum Festklemmen angezogen werden, was jedoch mit dem erwähnten Spannring nicht möglich ist. Nach der Erfindung; sollen nun diese Nachteile dadurch vermieden werden, daß die zwischen dem konischen Außenring und dem konischen Innenkörper mit entsprechendem Querschnitt versehenen Ringausschnitte, die zum Festklemmen des Drehmantels dienen, unabhängig voneinander hydraulisch -durch an eine gemeinsame Druckleitung angeschlossene Zylinder bewegt werden. Hierdurch ist es also möglich. die in Form von Ringausschnitten ausgebildeten Klemmteile gleichmäßig anzuziehen, und zwar auch dann, wenn die Mittelachsen .von Innensäule und Drehmantel nicht genau in einer Richtung liegen.There are already clamping devices in the form of wedges for the rotating casing known from radial drilling machines, which avoid the sag of Radialhohrmasch.inen should. However, these wedges cannot be evenly tightened at the same time. A clamping ring has already been used to avoid this disadvantage. Go berserk The individual clamping wedges are tightened on this ring, which is provided with inclined surfaces. However, this results in the disadvantage that the wedges with each rotation of the clamping ring only travel a certain distance. However, this is the position of the jammed Parts are not exactly concentric, which is always the case with the actual proportions Will be the case, the wedges will have to take a different path to jam be tightened, but this is not possible with the clamping ring mentioned. To the invention; these disadvantages are now to be avoided in that the between the conical outer ring and the conical inner body with a corresponding cross-section provided ring cutouts, which are used to clamp the rotating mantle, independently from each other hydraulically - through cylinders connected to a common pressure line be moved. This makes it possible. those designed in the form of ring cutouts Tighten clamping parts evenly, even if the central axes .von Inner column and rotating casing are not exactly in one direction.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigt Abb. i eine seitliche Ansicht der Klemmvorrichtung, teilweise im Schnitt, Abb.2 eine Draufsicht auf eine Schnittdarstellung gemäß Abb. i.An embodiment of the invention is shown in the drawing. Fig. I shows a side view of the clamping device, partly in section, Fig.2 is a plan view of a sectional view according to Fig. I.
Über die Säule i greift der Drehmantel 2. Die Säule i weist einen konischen Ringkörper 3 auf. Der Drehmantel 2 greift mit einem entgegengesetzt konisch gestalteten Ring q. über den Ring 3, so daß zwischen den Ringen 3 und 4. ein sich konisch nach oben verjüngender Raum 5 entsteht. In diesem konischen Raum 5 sind entsprechend konisch gestaltete Ringausschnitte 6 angeordnet, die durch Bohrungen 7 des Mantels 2 vermittels Stangen 8 hindurchgreifen. An den Stangen B sitzen Kolben 9, die in Zylindern io auf und ab bewegbar sind. Die Stangen greifen flüssigkeitsdicht durch die Zylinder. Auch sind die Kolben 9 flüssigkeitsdicht in den Zylindern angeordnet, beispielsweise vermittels Kolbenringen. Die Zylinder io stehen durch eine Leitung i i miteinander in Verbindung. Eine Steuervorrichtung in Form eines Kolbens 12 und eines Zylinders 13 mit entsprechender Verbindungsleitung 14 ermöglicht es, durch entsprechende Bewegung des Kolbens 12 die Flüssigkeit unter Druck zu setzen und hierdurch die Kolben 9 mit gleichmäßig verteiltem Druck zu heben bzw. bei einer Druckverminderung die Kolben 9 zu senken. Die Bewegung der Kolben tvird auf die konischen Ringausschnitte 6 übertragen.The rotating casing 2 engages over the column i. The column i has a conical ring body 3. The rotating casing 2 engages with an oppositely conical ring q. over the ring 3, so that between the rings 3 and 4 there is a conically tapering space 5. In this conical space 5, appropriately conically shaped ring cutouts 6 are arranged, which reach through bores 7 of the jacket 2 by means of rods 8. Pistons 9, which can be moved up and down in cylinders io, are seated on rods B. The rods grip through the cylinders in a liquid-tight manner. The pistons 9 are also arranged in a liquid-tight manner in the cylinders, for example by means of piston rings. The cylinders io are connected to one another by a line ii. A control device in the form of a piston 12 and a cylinder 13 with a corresponding connecting line 14 makes it possible to pressurize the liquid by moving the piston 12 accordingly and thereby to raise the piston 9 with evenly distributed pressure or to close the piston 9 when the pressure is reduced reduce. The movement of the pistons is transmitted to the conical ring cutouts 6.
