Description

Die Erfindung bezieht sich auf eine Vorrichtung, die an jeder Spitzendrehbank angebracht werden kann und es ermöglicht, hinterdrehte Werkzeuge, wie Gewindebohrer, schneckenförmige Stirnradfräser, Walzenfräser, Reibahlen usw., herzustellen. Bei bekannten Vorrichtungen dieser Art wird durch eine Kurvenscheibe ein am Drehbankbett schwingend gelagerter Hebel bewegt, der denThe invention relates to a device attached to each center lathe and it enables back-turned tools, such as taps, worm-shaped spur gear cutters, cylindrical cutters, reamers, etc. At acquaintances Devices of this type are fitted with a cam on the lathe bed oscillating lever moves that the

ίο Ouersupport gegenüber dem zwischen die Drehbankspitzen eingespannten Werkstück bewegt. Die Kurvenscheibe wirkt dabei auf den Hebel mittels eines auf diesem verstellbar gelagerten Tastsitiftes ein, um das Übersetzungsverhaltnis des Hebels und damit die Tiefe der Hinterdrehung ändern zu können.ίο Ouersupport towards the between the Lathe centers clamped workpiece moves. The cam has an effect the lever by means of an adjustable stylus mounted on this in order to set the transmission ratio of the lever and thus the depth of the back-turn to be able to change.

Von diesen Vorrichtungen unterscheidet sich der Gegenstand vorliegender Erfindung dadurch, daß der erwähnte Hebel die Kurvenscheibe konzentrisch zu ihrer Drehachse umgreift, wodurch eine größere Verstellbarkeit des Hebelverhältnisses erreicht werden kann als bei geradliniger Verschiebung des Taststiftes. The subject matter of the present invention differs from these devices in that the mentioned lever engages around the cam concentrically to its axis of rotation, whereby a greater adjustability of the lever ratio can be achieved than when moving the stylus in a straight line.

Auf der beiliegenden Zeichnung ist diese Erfindung dargestellt, und zwar zeigtThis invention is illustrated in the accompanying drawing, namely shows

Auf einer Welle g sitzt die Spiralformscheibe b, gegen weiche der mittels einer Hülse k in dem Doppelhebel d verschieb- und feststellbare Taststift c anläuft. Der Hebel bewegt durch die Stange e den Ouersupport f und damit den Stahl s gegenüber dem Werkstück t- Der Hebel d ist konzentrisch um die Welle g gekrümmt, so daß eine Verstellung des Stiftes c in weitestgehendem Maße möglich ist, ohne den Stift in seiner Längsrichtung gegen die Spkalformscheibe verstellen zu müssen.The spiral- shaped disk b is seated on a shaft g , against which the stylus c, which can be displaced and locked in the double lever d by means of a sleeve k, runs up . The lever moves through the rod e the Ouersupport f and thus the steel s against the workpiece t- The lever d is curved concentrically around the shaft g , so that an adjustment of the pin c is largely possible without the pin in its longitudinal direction to have to adjust against the Spkalformscheibe.
