Description

KAISERLICHESIMPERIAL

PATENTAMT,PATENT OFFICE,

Bei den Kopierfräsmaschinen wird bekanntlich das zu bearbeitende Werkstück auf einem Tisch befestigt, der sirh gleichmäßig dreht und so die zu fräsenden Flächen an einem umlaufenden Fräser vorbeibewegt. Dieser Fräser wird hierbei mit seinem Schlitten durch Feder- oder Gewichtszug an die zu bearbeitenden Flächen angedrückt und von einer auf der Drehachse des Werktisches befestigten ίο Schablone in seiner Bewegung begrenzt.In the case of copy milling machines, the workpiece to be machined is known to be on a Fixed table that turns evenly and so the surfaces to be milled on one rotating cutter moved past. This cutter is doing this with its slide Spring or weight pull pressed against the surfaces to be processed and opened by one the axis of rotation of the workbench attached ίο the template is limited in its movement.

Da nun der Werktisch stets mit derselben Geschwindigkeit umläuft, ändert sich naturgemäß die Geschwindigkeit am Umfange des zu fräsenden Werkstückes, beispielsweise bei zu fräsenden Exzentern r, in dem Maße, in welchem die achsiale Entfernung der zu bearbeitenden Fläche vom Drehpunkt des Werktisches steigt oder abnimmt, d. h. die mechanische Arbeit ist ungleich. Aus diesem Umso stand müssen auch die auf dieser Maschine hergestellten .Werkstücke auf Genauigkeit nachgearbeitet werden.Since the work table now always rotates at the same speed, the speed naturally changes at the circumference of the workpiece to be milled, for example in the case of eccentrics r to be milled, to the extent that the axial distance of the surface to be machined from the pivot point of the work table increases or decreases, ie the mechanical work is unequal. For this reason, the workpieces produced on this machine must also be reworked for accuracy.

Dieser Nachteil wird durch den Gegenstand vorliegender Erfindung beseitigt. Auf der Zeichnung stelltThis disadvantage is eliminated by the subject matter of the present invention. On the drawing represents

Fig. ι den Aufriß einer Schablonenfräsmaschine dar.Fig. Ι the front view of a template milling machine.

Fig. 2 zeigt den Grundriß des Antriebes.Fig. 2 shows the plan of the drive.

Die Bewegungsübertragung der Antriebwelle e auf das den Werktisch α bewegende Getriebe f erfolgt vermittels des konischen Riemenantriebes c, d; während eine um h drehbare, bei i mit dem Schlitten g verbundene Riemengabel k bei Verschiebung des Schlittens g den Riemenantrieb verschiebt und so das Übersetzungsverhältnis des Riemenantriebes derart regelt, daß in gleichem Maße, in welchem sich der Fräser b vom Mittelpunkt des Werktisches entfernt, der Werktisch eine verzögerte Drehbewegung erhält und umgekehrt. The transmission of movement from the drive shaft e to the gear unit f moving the workbench α is carried out by means of the conical belt drive c, d; during a rotatable by h, wherein i with the carriage g associated belt fork k upon displacement of the carriage g displaces the belt drive and regulates so the gear ratio of the belt drive in such a way that the same degree, in which the milling cutter b away from the center of the work table, the Workbench receives a delayed rotary movement and vice versa.

Die Bewegung des vom Zahnrad I und Gewichtshebel 0 in Richtung des Pfeiles (Fig. 1) verschobenen Schlittens g wird in bekannter Weise von der Schablone s begrenzt, während das Zahnrädergetriebe m, η ebenfalls in bekannter Weise die Bewegung auf die Fräserwelle p und den Fräser b überträgt.The movement of the slide g displaced by the gear wheel I and weight lever 0 in the direction of the arrow (FIG. 1) is limited in a known manner by the template s, while the gear drive m, η also in a known manner controls the movement of the cutter shaft p and the cutter b transmits.

Es ist zwar bekannt, die Drehgeschwindigkeit von Werkstückhaltern entsprechend der Entfernung der Arbeitsstelle vom Werkzeug mittels eines Kegelscheibenantriebes zu regeln, dessen Riemen durch eine schwingende Riemengabel verschoben wird. Bei Kopierfräsmaschinen hat man jedoch bisher noch nicht die Verschiebung des den Fräser tragenden Schlittens zur Regelung der Umdrehungsgeschwindigkeit des das Werkstück tragenden Tisphes benutzt.Although it is known, the speed of rotation of workpiece holders according to To regulate the distance of the work place from the tool by means of a conical disk drive, whose belt is moved by a swinging belt fork. For copy milling machines however, one has not yet moved the slide carrying the milling cutter to regulate the speed of rotation of the tisphes carrying the workpiece used.
