Description

Die Erfindung betrifft Drehbanklünetten mit einem mit Festspannvorrichtungen versehenen, von einem Kugellager getragenen Laufring. Das Wesen der Erfindung besteht darin, daß die Fußplatte des Kugellagers mittels einer Zwischenplatte auf einer auf dem Drehbankbett feststellbaren Grundplatte quer zum Bett verschiebbar ist, wobei die Fußplatte auf der Zwischenplatte um eine durch die LagermitteThe invention relates to lathe bezels with a clamping device provided with, Race ring carried by a ball bearing. The essence of the invention is that the foot plate of the ball bearing by means of an intermediate plate on one on the lathe bed lockable base plate is slidable across the bed, with the foot plate on the Intermediate plate around one through the center of the bearing

ίο gehende senkrechte Achse drehbar ist. Bei dieser Ausbildung der Lünette ist es möglich, auch bei großer Ouerverstellung eine Drehung der Lünette um die senkrechte Achse zu erreichen. ίο walking vertical axis can be rotated. at With this design of the bezel, it is possible to rotate even with a large Ouerverstellung the bezel to reach the vertical axis.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.The subject matter of the invention is shown in the drawing, for example.

Abb. ι ist eine Seitenansicht, teilweise im Schnitt;Fig. Ι is a side view, partly in section;

Abb. 2 ist ein senkrechter Achsialschnitt;Fig. 2 is a vertical axial section;

Abb. 3 ist ein Grundriß der Grundplatte des Lagers.Figure 3 is a plan view of the base of the bearing.

In einem Kugellager α mit dem festen Ring b und dem drehbaren Ring c ist ein Laufring d angeordnet. Der Laufring besitzt einen seitlieh von dem Lagerkörper α sich erstreckenden Flansch e. In diesem Flansch e sind die Spannvorrichtungen f für das Werkstück angeordnet. Die Spannvorrichtungen bestehen im vorliegenden Falle aus radial verschiebbaren, aber nicht drehbaren Zahnstangen, in welche unverschiebbare Einstellspindeln g eingreifen. Man könnte natürlich auch einfache Spannschrauben mit Gegenmuttern verwenden oder ein zentrisch spannendes FutterA race ring d is arranged in a ball bearing α with the fixed ring b and the rotatable ring c. The race has a flange e extending laterally from the bearing body α. The clamping devices f for the workpiece are arranged in this flange e. In the present case, the clamping devices consist of radially displaceable, but non-rotatable toothed racks in which non-displaceable adjusting spindles g engage. Of course, you could also use simple clamping screws with lock nuts or a centric clamping chuck

o. dgl.or the like

Der Lagerkörper α wird von zwei Säulen h getragen, die in einer Fußplatte i befestigt sind. Die Fußplatte i ist auf einer Grundplatte k angeordnet, die auf dem Drehbankbett befestigt wird. Zwischen der Grundplatte und der Fußplatte ist ein Zwischenlager I angeordnet, welches einen abwärts ragenden Fortsatz m besitzt. Dieser Fortsatz enthält eine Bohrung mit Muttergewinde, durch das sich eine Schraubenspindel η erstreckt, die in der Grundplatte k gelagert ist. Mit Hilfe der Schraubenspindel η läßt sich die Zwischenlage I mit der Fußplatte i senkrecht zur Drehbankachse verschieben. In der Zwischenlage I befinden sich zwei Stiftschrauben 0, die durch einen Schlitz/» der Fußplatte hindurchragen. Der Schlitz p besitzt die Form eines Kreisbogens, dessen Mittelpunkt in der senkrechten Mittelachse des Lagers liegt. Nach Lockern der Muttern q ist es möglich, die Fußplatte auf der Grundplatte um einen gewissen Betrag zu drehen.The bearing body α is supported by two columns h which are fastened in a base plate i. The foot plate i is arranged on a base plate k which is attached to the lathe bed. An intermediate bearing I is arranged between the base plate and the foot plate, which has a downwardly projecting extension m . This extension contains a bore with a nut thread through which a screw spindle η extends, which is mounted in the base plate k. With the help of the screw spindle η , the intermediate layer I can be moved with the footplate i perpendicular to the lathe axis. In the intermediate layer I there are two studs 0 which protrude through a slot / »in the footplate. The slot p has the shape of an arc of a circle, the center of which lies in the vertical central axis of the bearing. After loosening the nuts q it is possible to turn the foot plate on the base plate by a certain amount.

Infolge der Verschiebbarkeit und Drehbarkeit des Lagers α ist es möglich, kegelförmige Flächen zu drehen und zu bohren.As a result of the displaceability and rotatability of the bearing α , it is possible to rotate and drill conical surfaces.

Die neue Lünette kann mit Vorteil beim Bearbeiten von Wagenachsen mit bereits gebogenen Schenkeln, von Nabenbüchsen mit kegelförmiger Bohrung, von Arbeitsspindeln mit Morsekonus, Mühleisen, Kurbelwellen usw. benutzt werden.The new steady rest can be of advantage when machining carriage axes with already curved Legs, of hub sleeves with a conical bore, of work spindles with Morse taper, mill iron, crankshafts etc. can be used.

Die dargestellte Lagerung läßt sich ferner bei Verwendung je eines Kugellagers zu beiden Seiten der Spannscheibe als Lagerung für Riffelmaschinen verwenden.The storage shown can also be used when using one ball bearing for both Use the sides of the conical spring washer as a bearing for corrugating machines.
