Description

Druckluftverteilerring an Rundtischfräsmaschinen od. dgl. Die Erfindung bezieht sich auf einen Druckluftverteilerring, der bei Rundfräsmaschinen oder Rundfräsautomaten Verwendung finden soll, um pneumatischen Spannvorrichtungen, die auf dem Rundfrästisch aufgebaut sind, die benötigte Druckluft zuzuführen. Zu diesem Zweck ist ein Druckluftverteilerring am Mittelständer der Maschine vorgesehen. Die Erfindung hat sich die Aufgabe gestellt, einen derartigen Druckluftverteilerring so auszubilden, daß nicht nur eine gute Abdichtung der Luftzuführung erreicht wird, sondern daß auch eine leichte Drehbarkeit der notwendigen Teile erzielt wird.Compressed air distribution ring on rotary table milling machines or the like. The invention refers to a compressed air distribution ring that is used on circular milling machines or automatic circular milling machines Should be used to pneumatic clamping devices that are on the circular milling table are constructed to supply the required compressed air. A compressed air distribution ring is provided for this purpose provided on the center column of the machine. The invention has the task of to train such a compressed air distribution ring so that not only a good one Sealing of the air supply is achieved, but that easy rotatability of the necessary parts is achieved.

Um dies zu erreichen, wird gemäß der Erfindung vorgeschlagen, den feststehenden mit der Druckluftzuleitung verbundenen Teil als im Querschnitt U-förmigen Außenring auszubilden, in dem ein mit dem Maschinentisch umlaufender Innenring mit axialen Druckluftentnahmekanälen dichtend angeordnet ist, der mittels Wälzkörpern durch einen am Außenring befestigten Gegendruckflanschring axial gelagert ist.To achieve this, it is proposed according to the invention, the fixed part connected to the compressed air supply line as a U-shaped cross-section Form the outer ring, in which an inner ring rotating with the machine table with axial compressed air extraction channels is arranged sealingly by means of rolling elements is axially supported by a counterpressure flange ring attached to the outer ring.

Auf diese Weise wird der hohe Axialdruck und die hierdurch entstehende Gleitreibung zwischen dem Innenring und dem Gegendruckring durch Verwendung der Wälzkörper, insbesondere von Kugeln, in eine Rollreibung umgewandelt. Hierdurch wird die erforderliche Antriebskraft zum Drehen des Innenringes niedrig gehalten.In this way, the high axial pressure and the resulting Sliding friction between the inner ring and the counter pressure ring by using the Rolling bodies, especially balls, converted into rolling friction. Through this the drive force required to rotate the inner ring is kept low.

Vorteilhaft wird der Gegendruckflanschring über Druckelemente, z. B. über Tellerfedern, mit dem Außenring verbunden. Hierdurch erzielt man eine einwandfreie Abdichtung auch während des Betriebes der Maschine, da der umlaufende Innenring durch diese Druckelemente gegen den Außenring gepreßt wird, so daß die zwischen dem Innenring und dem Außenring vorgesehenen Dichtelemente, z. B. Ringschnurdichtungen, immer einwandfrei anliegen.The counterpressure flange ring is advantageous via pressure elements such. B. connected to the outer ring via disc springs. This achieves a perfect Sealing also during operation of the machine because of the surrounding inner ring is pressed by these pressure elements against the outer ring, so that the between the inner ring and the outer ring provided sealing elements, for. B. ring cord seals, always fit perfectly.

Durch Verwendung der Druckelemente wird gleichzeitig ein etwaiger Verschleiß ausgeglichen, da der Innenring selbsttätig durch die Druckelemente nachgestellt wird.By using the pressure elements, a possible Compensated for wear as the inner ring is automatically adjusted by the pressure elements will.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Querschnitt dargestellt. In dem feststehenden Mittelständer 1, beispielsweise einer Rundtischfräsmaschine, ist ein U-förmiger Außenring 2 angeordnet, in dem sich ein Innenring 3 befindet. Dieser Innenring 3 wird gehalten durch einen Gegendruckflanschring 4, der durch Schrauben 5 und 6 unterZwischenlage vonDruckelementen, z. B. von Tellerfedern 7, mit dem Außenring 2 verbunden ist. Zwischen diesem Gegendruckflanschring 4 und dem Innenring 3 sind Wälzkörper, z. B. Kugeln 8, mit einem nicht dargestellten Käfig angeordnet, so daß eine Rollreibung zwischen dem Innenring 3 und dem Gegendruckflanschring 4 vorhanden ist. Durch ein Verbindungsorgan 9 steht der Innenring 3 mit dem nicht dargestellten Maschinentisch in Verbindung und wird somit mit dem Tisch in Umdrehung versetzt.In the drawing, an exemplary embodiment of the subject matter of the invention is shown in cross section. In the stationary center stand 1, for example a rotary table milling machine, a U-shaped outer ring 2 is arranged, in which an inner ring 3 is located. This inner ring 3 is held by a counterpressure flange ring 4, which is secured by screws 5 and 6 with the interposition of pressure elements, e.g. B. of disc springs 7, is connected to the outer ring 2. Between this counterpressure flange ring 4 and the inner ring 3 are rolling elements, for. B. balls 8, arranged with a cage, not shown, so that a rolling friction between the inner ring 3 and the counterpressure flange ring 4 is present. The inner ring 3 is connected to the machine table (not shown) by a connecting element 9 and is thus set in rotation with the table.

Zu dem Außenring 2 führt eine Druckluftleitung 10, die in eine Ringnut 11 mündet. In dem Innenring sind axiale Druckluftentnahmekanäle 12 angebracht, die jeweils zu einer auf dem Maschinentisch aufgebauten Spannvorrichtung führen. Um eine gute Abdichtung zwischen dem Außenring 2 und dem Innenring 3 zu erreichen, sind zu beiden Seiten der Nut 11 Ringschnurdichtungen 13 und 14 vorgesehen. Sollte ein Verschleiß auftreten, so wird der Innenring selbsttätig durch die Federn 7 nachgestellt. A compressed air line 10, which opens into an annular groove 11, leads to the outer ring 2. Axial compressed air extraction ducts 12 are attached in the inner ring, each of which leads to a clamping device installed on the machine table. In order to achieve a good seal between the outer ring 2 and the inner ring 3, ring cord seals 13 and 14 are provided on both sides of the groove 11. Should wear occur, the inner ring is automatically readjusted by the springs 7.
