Description
Die Erfindung betrifft eine Vorrichtung· zum Fräsen von Keilnuten in Hohlkörper, deren Fräser von an der Triebswelle sitzenden Mitnehmerstiften angetrieben wird. The invention relates to a device for milling keyways in hollow bodies, the milling cutter of which is driven by driver pins located on the drive shaft.
Die bisher bekannten Vorrichtungen dieser Art haben den Nachteil, daß die mit den Mitnehmerstiften betriebene Antriebswelle in dem Werkzeughalter exzentrisch gelagert sein muß, damit der Eingriff der Mitnehmerstifte in den Fräser seitlich erfolgt.The previously known devices of this type have the disadvantage that with the driving pins driven drive shaft must be eccentrically mounted in the tool holder so that the engagement of the driving pins in the Cutter is done on the side.
Dies bedingt besondere Einstellvorrichtungen. This requires special adjustment devices.
Zur Vermeidung dieser Übelstände ist bei der vorliegenden Erfindung zwischen der mit den Mitnehmerstiften versehenen Antriebswelle und dem anzutreibenden Fräser ein Zwischenrad eingeschaltet, welches nur so breit ist, daß eine Seitenkante des Zahnrades mit der Mitte der Antriebswelle zusammenfällt. Die Zähne desselben sind an den inneren Kanten seitlich abgeschrägt und abgerundet, so daß auf diese Weise der richtige Eingriff zwischen den Zapfen der Antriebswelle und der inneren Seitenkante des Zahnrades, wie aus der Abb. 1 und Schnitt C-D ersichtlich, bewerkstelligt wird.To avoid these inconveniences, an intermediate gear is switched on between the drive shaft provided with the driving pins and the milling cutter to be driven, which is only so wide that one side edge of the gear coincides with the center of the drive shaft. The teeth of the same are laterally beveled and rounded at the inner edges, so that the correct engagement between the journals of the drive shaft and the inner side edge of the gear, as shown in Fig. 1 and section CD , is achieved.
Ein direkter Eingriff der Zapfen in den Fräser ist nicht tunlich, da an dem FräserA direct engagement of the tenons in the milling cutter is not possible because it is on the milling cutter
die Flanken nicht abgeschrägt und abgerundet werden können, wenn derselbe eine scharfkantige Nut schneiden soll. Der Fräser müßte dann außerdem mit seiner Seitenkante mit der Mitte der Antriebswelle zusammenfallen, wodurch die Breite der Fräser unzulässig' beschränkt würde.the flanks cannot be beveled and rounded if the same is a sharp-edged one Cut groove. The milling cutter would then also have to with its side edge with the Coincide center of the drive shaft, whereby the width of the milling cutter inadmissibly 'restricted would.

The mode of action is as follows:

Es ist aus der Zeichnung ersichtlich, daß die Welle b im Werkzeughalter α konzentrisch angeordnet ist und der richtige Eingriff der Antriebszapfen in das Zahnrads dadurch erreicht wird, daß dieses Zahnrad mit seiner einen Seitenkante mit der Mitte der Antriebswelle zusammenfällt.It can be seen from the drawing that the shaft b is arranged concentrically in the tool holder α and the correct engagement of the drive pin in the gear is achieved in that one side edge of this gear coincides with the center of the drive shaft.
