Description

Es ist bekannt, die Hinundherbewegung der Schrämstange bei Stangenschrämmaschinen mittels eines Doppelhebels herbeizuführen, der an einem Ende durch eine Kurbelstange angetrieben wird, wobei das andere Ende die Schrämstange axial verschiebt. Bei den Antriebsvorrichtungen dieser Art liegt der Drehpunkt des Doppelhebels fest, so daß das Angriffsgelenk dieses Hebels an der Sehrämstange senkrecht zur Schrämstangenachse verschiebbar sein muß.The reciprocating motion of the cutter bar in bar cutters is known to bring about by means of a double lever, which is driven at one end by a connecting rod, the other end the The cutting bar moves axially. In the case of drive devices of this type, the fulcrum is located of the double lever so that the engagement joint of this lever on the Sehrämstange must be displaceable perpendicular to the cutting rod axis.

Nach der Erfindung ist der Hebeldrehpunkt nachgiebig angeordnet, so daß die Hebelenden lediglich durch je ein Drehgelenk an den beiden zu verbindenden Organen, Kurbel und Schrämstange, befestigt sind. Der Vorteil dieser Anordnung liegt in dem Fortfall der Schiebergelenke an den Angriffspunkten, wodurch die Konstruktion sehr vereinfacht wird. Zweckmäßig wird die Einrichtung so getroffen, daß der Hebel in einem am Gehäuse angeordneten Lenker gelagert ist und seine Hinundherbewegung über ein von der Schrämstange bewegtes Schneckengetriebe durch s*5 einen Exzenterantrieb erhält.According to the invention, the fulcrum is resiliently arranged so that the lever ends only by a swivel joint on the two organs to be connected, crank and Cutting rod, are attached. The advantage of this arrangement lies in the elimination of the Slide joints at the points of application, which greatly simplifies the construction. The device is expediently made so that the lever is arranged in a on the housing Handlebar is mounted and its reciprocation via one of the cutting bar Moving worm gear is given an eccentric drive by s * 5.

In der Zeichnung ist die Vorrichtung in der Seitenansicht dargestellt.In the drawing, the device is shown in side view.

Auf der in an sich bekannter Weise angetriebenen Schrämstange α ist ein Zahnrad b angeordnet, und zwar so, daß die Schrämstange α in dem genannten Zahnrad verschiebbar ist. Dieses Zahnrad steht in Eingriff mit dem Zahnrad c, auf dessen Welle d die bei e und f in dem Gehäuse ν gelagerte Schnecke g angeordnet ist. Letztere arbeitet auf das Schneckenrad i, das mit dem Exzenterzapf en k versehen ist. An diesen greift die Schubstange m an, die bei η an den Hebel 0 angelenkt ist. Der Hebel o, der um den Bolzen p in dem Lenker q drehbar ist, ist mit seinem anderen Ende an Bolzen s angelenkt, welche an einem drehbaren, aber unverschiebbaren Bunde auf der Schrämstange α angeordnet sind.A gear wheel b is arranged on the cutting bar α, which is driven in a manner known per se, in such a way that the cutting bar α can be displaced in said gear wheel. This gear wheel is in engagement with the gear wheel c, on whose shaft d the worm g mounted at e and f in the housing ν is arranged. The latter works on the worm wheel i, which is provided with the eccentric pin en k . The push rod m , which is hinged to the lever 0 at η , acts on this. The lever o, which is rotatable about the bolt p in the link q , is articulated at its other end to bolts s , which are arranged on a rotatable but immovable collar on the cutting rod α .

Die Wirkungsweise der neuen Vorrichtung ist folgende:The new device works as follows:

Die Drehbewegung der Schrämstange a wird durch das Zahnradgetriebe b, c auf die Wellet? übertragen. Durch die Schneckeg wird diese Drehbewegung auf das Schnecken- 5<> rad i weitergeleitet, wodurch der Schubstange m und damit auch der Schrämstange a durch den Hebel 0 eine hin und her gehende Bewegung erteilt wird.The rotational movement of a Schrämstange b through the gear train, c to the Wellet? transfer. This rotational movement is g by the screw forwarded to the worm 5 <> rad i, whereby the push rod and thus also the Schrämstange a m by the lever 0 a reciprocating movement is imparted.
