Description

Drehkopf für Wellendrehmaschinen Es sind Drehköpfe für Wellendrehmaschinen bekannt, bei denen axial hinter der Messerebene, in der sich mehrere Drehstähle befinden, Backen aus gehärtetem Stahl angeordnet sind, die die Aufgabe haben, die Welle zentrisch zu führen und auch bei .entsprechend stärkerem Anzug zu polieren.Turning head for shaft lathes These are turning heads for shaft turning machines known, where axially behind the knife plane, in which there are several turning tools are located, jaws made of hardened steel are arranged, which have the task of To guide the shaft centrically and to polish it even with a correspondingly stronger tightening.

Es hat sich herausgestellt, daß die Werkstücke mittels dieses Drehkopfes nicht mit einer Genauigkeit von wenigen hundertstel Millimetern hergestellt und poliert werden können. Denn die neben der Messerebene liegenden Führungsbacken können das Werkstück nicht zentrieren, zumal, da es praktisch unmöglich ist, alle Drehstähle gleichmäßig einzustellen. Daher kann das Werkstück nicht mit genügender Genauigkeit auf den Durchmesser abgedreht werden, der nach dem Polieren die gewünschte Wellenstärke ergibt. Wird in der Messerebene nur ein Drehstahl angeordnet, was mit Rücksicht auf genaue Einstellung notwendig ist, so wird das Werkstück infolge des @einseitig wirkenden Schneiddruck.es ungleichmäßig abgedreht. Auch sind Polierbacken aus gehärtetem Stahl für das Polieren unbrauchbar.It has been found that the workpieces by means of this rotary head not manufactured with an accuracy of a few hundredths of a millimeter and can be polished. Because the guide jaws located next to the knife level can do not center the workpiece, especially since it is practically impossible to use all turning tools adjust evenly. Therefore, the workpiece cannot be made with sufficient accuracy be turned to the diameter that, after polishing, the desired shaft strength results. If only one turning tool is arranged in the knife plane, what with consideration exact setting is necessary, the workpiece will be one-sided as a result of the @ acting cutting pressure. it is turned off unevenly. Polishing jaws are also made of hardened Steel useless for polishing.

Nach der Erfindung können Wellen oder Rohre dadurch auf genaues Maß bearbeitet und poliert werden, daß außer den axial hinter der Messerebene angeordneten Polierrollen in der Messerebene Führungsbacken oder -rollen angeordnet sind, durch die das Werkstück genau zentriert wird. Diese genaue Führung des Werkstückes in der Messerebene gestattet selbst bei Anwendung eines einzigen Drehstahles ein vollkommen genaues Zentrieren des Werkstückes, so daß mittels der Polierrollen, die etwas stärker angezogen sind als die in der Messerebene liegenden Führungen, ein poliertes Werkstück erhalten wird, dessen Durchmesser innerhalb kleinster Grenzen genau ist.According to the invention, shafts or tubes can thereby be made to exact dimensions machined and polished that apart from the axially arranged behind the knife plane Polishing rollers are arranged in the knife level guide jaws or rollers by which the workpiece is precisely centered. This precise guidance of the workpiece in the knife level allows a perfect even when using a single turning tool precise centering of the workpiece, so that by means of the polishing rollers, the somewhat stronger are attracted as the guides lying in the plane of the knife, a polished workpiece is obtained whose diameter is accurate within the smallest limits.

Es sind Drehköpfe bekannt, bei denen die in der Messerebene liegenden Führungsbacken oder -rollen axial über die Messerebene hinaus verlängert sind, um dadurch die Zentrierung zu verbessern und die Abnutzung der Führungskörper zu vermindern. Indessen ist mittels dieser Drehköpfe ein genaues Drehen und Polieren nicht möglich, da die in der Messerebene und neben dieser liegenden Führungskörper ein einheitliches Ganzes bilden und nur zusammen eingestellt werden können, während das Polieren der Welle voraussetzt, daß die in der Messerebene liegenden Führungskörper und die Polierrollen unabhängig voneinander eingestellt werden können.There are rotary heads known in which the lying in the knife plane Guide jaws or rollers are extended axially beyond the knife plane to thereby improving the centering and reducing the wear and tear on the guide body. However, precise turning and polishing is not possible with these turning heads, because the guide body lying in the knife plane and next to it is a uniform Form a whole and can only be adjusted together while polishing the The shaft assumes that the guide body and the polishing rollers are in the plane of the knife can be set independently of each other.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel.The drawing illustrates an embodiment.

Abb. r ist eine Ansicht des Drehkopfes und Abb. 2 ein Längsschnitt.Fig. R is a view of the rotating head and Fig. 2 is a longitudinal section.

Der Drehkopf besteht aus einer Scheibe a, auf deren Vorderseite Führungen b für drei Führungsbacken oder -rollen c angeordnet sind. Diese Führungsbacken können durch Schraubend radial eingestellt werden. Zwischen zwei dieser Backen liegt ein breiter Drehstahle, der in einem Schlitz eines Schlittens f mittels Schraube verschiebbar ist. Dieser Schlitten ist in einer an der Scheibe a angegossenen Führung verschiebbar.The rotating head consists of a disk a with guides on the front side b for three guide jaws or rollers c are arranged. These guide jaws can can be adjusted radially by screwing. There is one between two of these jaws wider Turning tools, which in a slot of a slide f means Screw is displaceable. This carriage is in a cast on the disc a Slidable guide.

In axialer Richtung hinter den Führungsbacken c und versetzt zu den letzteren sind Polierrollen i angeordnet. Diese sind mittels Zapfen in Schlitten k gelagert, die in ihren Führungen b mit Hilfe von Schrauben m radial verschiebbar sind.Polishing rollers i are arranged in the axial direction behind the guide jaws c and offset from the latter. These are mounted by means of pins in carriages k, which are radially displaceable in their guides b with the aid of screws m.

Vermöge der beschriebenen Anordnung können die Führungsbacken und Polierrollen unabhängig voneinander eingestellt werden. Die Führungsbacken werden demgemäß jentsprechend den Anforderungen des Schneidvorganges eingestellt, derart, daß die Welle auf den gewünschten Durchmesser abgedreht wird. Die Polierrollen i jedoch werden etwas schärfer angezogen als die Backen, so daß sie die Wellen polieren. Je nach dem Grad der Politur und der Beschaffenheit des Werkstoffes werden die Rollen mehr oder weniger ,stark angezogen. Die Einstellung der Teile des Schälkopfes und die Bearbeitung des Werkstückes gestaltet sich in der Weise, daß zunächst die Führungsbacken c und der Stahle mit Hilfe eines zylindrischen Dornes und anschließend die Polierrollen mittels desselben Dornes eingestellt werden. Die Polierrollen werden nach Entfernen des Dornes gleichmäßig etwas stärker angezogen. Das Werkstück wird eingeführt und bearbeitet. Stellt sich heraus, daß das Werkstück nicht genügend poliert wird, so werden die Polierrollen stärker angezogen. Ebenso ist eine dauernde Kontrolle dies Durchmessers des polierten Werkstückes möglich.By virtue of the arrangement described, the guide jaws and Polishing rollers can be set independently of each other. The guide jaws are adjusted accordingly to the requirements of the cutting process, in such a way, that the shaft is turned to the desired diameter. The polishing rollers i however, they are tightened somewhat more sharply than the jaws so that they polish the shafts. Depending on the degree of polish and the nature of the material, the roles more or less, strongly attracted. Adjustment of the parts of the peeling head and the machining of the workpiece is designed in such a way that first the guide jaws c and the steels with the help of a cylindrical mandrel and then the polishing rollers can be adjusted by means of the same mandrel. The polishing rollers are after removal of the mandrel tightened evenly a little more. The workpiece is introduced and processed. If it turns out that the workpiece is not polished enough, so the polishing rollers are tightened more strongly. This is also a constant control Diameter of the polished workpiece possible.
