Description
Vorrichtung zum Fräsen für Drehbänke mit Leitspindel und selbsttätiger Zon Gegenshuid vorliegender Erfiudung be- zieht sich auf eine Vorrichtung zum Fräsen tür Drehl) änke mit Leitspindel und selbst tätiger Yorschubeinrichtung.
Das Wesentliche besteht darin, dass von einer Riemenseheibe einerseits der dureli die Leitspindel in bekannter Weise hin-nnd lier- bcwegbare Schneckenfräser gedreht und anlerseits durch ein ausziehbares Kardangelenk. durch Kegel- und Wechselräder ein am Reit- stock anzubringender Teillappen bewegt wird, der das zu fräsende Werkstück ent- sprechend der Bewegung des Schneckenfräsers dreht. Die Antriebsachse des Schnecken fräsers ist zweckmässig in einer senkrechten Ebene verstellbar.
Durch diese Anordnung wird erreiclit, dass Fräsarbeiten, die sonst nur mittelst einer Fräsmaschine herzusteHen sied, aucl auf der Drehbank ausgeführt werden können.
Zum besseren Verständnis der Erfindung sind in Fig. 1 und 2 der Zeichnung zwei beispielsweise Ausführungsformen derartiger Fräsvorrichtungen dargestellt. tr ist ein zu fräsendes Zahnrad, b der Schneckenfräser. welcher am Fräsapparat c befestigt und mit diesem senkrecht verstell I) ist. Der Fräsapparat c ist auf dem Sup port der Drehbank angeordnet. Die durci- gehende Frässpindel. welche den Schneckeniräser b an dem einen Ende auiweist, ist ; zum Zwecke des vibrationsfreien Arbeitens doppelt gelagert.
Auf die Frässpindel ist ein in deiii Gehäuse f gelagertes Schneckenrad l'eSt aufgekeilt. mit dem eine auf der Welle der Riemenscheibe e sitzende Schnecke zu sammenarbeitet. su dass die Frasspindel ihren Antrieb von der Riemenschibe erhält. Die Riemenscheibe c kann. wie in den Figuren gezeigt, inner- oder ausserhalb der Fräseinrichtung angeordnet sein. Die Bewegung der letzteren wird ausserdem durch ein ausziehbares Kardangelenk g entweder zunächst durch in einer Schere i gelagerte Wechselräder l und dann durch Kegelräder h (Fig.
1) oder erst durch letzter" und dann durch die Wechselräder 1 (Fig. 2) auf einen am Reitstock der Drehbank sitzenden Teilapparat k übertragen. Dieser (in Fig. 2 nicht dar ggestellt) dreht (Ia., das zu fräsende Rad a entsprechend der Bewegung des Schneckenfräsers.
Sobald die Drehbank-Wechselräder eingeschaltet werden. wird der Fräsapparat in bebannter Veise mittelst der Leitspindel hin-und hergeschoben.während das Fräsen dureh den Fräser b erfolgt, der von der Riemenseheibe c seinen Antrieb erfahrt.
Device for milling for lathes with lead screw and automatic zone counterpart of the present invention relates to a device for milling for lathes with lead screw and automatic feed device.
The essential thing is that, on the one hand, the worm cutter, which can be moved in a known manner, is rotated by a belt pulley and on the other hand by an extendable universal joint. A partial tab to be attached to the tailstock is moved by bevel and change gears, which turns the workpiece to be milled according to the movement of the worm cutter. The drive axis of the worm cutter is expediently adjustable in a vertical plane.
By this arrangement it is achieved that milling work, which otherwise could only be done by means of a milling machine, can also be carried out on the lathe.
For a better understanding of the invention, two exemplary embodiments of such milling devices are shown in FIGS. 1 and 2 of the drawing. tr is a gear to be milled, b the worm cutter. which is attached to the milling apparatus c and vertically adjustable with this I). The milling machine c is arranged on the sup port of the lathe. The continuous milling spindle. which has the worm cutter b at one end; double bearings for the purpose of vibration-free operation.
A worm wheel l'eSt mounted in the housing f is keyed onto the milling spindle. with which a worm seated on the shaft of the pulley e cooperates. su that the milling spindle gets its drive from the belt pulley. The pulley c can. as shown in the figures, be arranged inside or outside the milling device. The movement of the latter is also controlled by an extendable universal joint g, either first by change gears l mounted in scissors i and then by bevel gears h (Fig.
1) or only through the last "and then through the change gears 1 (FIG. 2) to a dividing device k seated on the tailstock of the lathe. This (not shown in FIG. 2) rotates (Ia., The wheel a to be milled accordingly the movement of the worm cutter.
As soon as the lathe change gears are switched on. the milling device is pushed back and forth in a well-known manner by means of the lead screw, while milling is carried out by milling cutter b, which is driven by belt pulley c.
