Description

Beim Abdrehen unrunder Werkstücke, insbesondere auf Vierkantblockdrehbänken, wird der Schneidwinkel des Stahles dadurch erhalten, daß der Stahlhalter während des Arbeitsganges Schwenkbewegungen um die Stahlspitze herum ausführt. Zu diesem Zwecke wurde bisher der Stahlhalter als Schieber ausgebildet, der in einer Rundführung hin und her bewegt wurde. Bei dieser Ausbildung tritt infolge der großen Beanspruchung der Führungsbahn bald ein Verschleiß ein, der den ordnungsgemäßen Betrieb der Maschine empfindlich stören kann. Dieser Verschleiß wird dadurch besonders gefördert, daß zwischen die aufeinandergleitenden Flächen Drehstaub gelangt. Die Verwendung von Rollen steuert diesem Nachteil auch nur mangelhaft.When turning non-round workpieces, especially on square block lathes, the cutting angle of the steel obtained in that the steel holder during the Swiveling movements around the steel point. To this Purposes so far, the steel holder has been designed as a slide, which is in a round guide was moved back and forth. In this training occurs as a result of the large Stress on the guideway soon results in wear and tear, which prevents proper operation can interfere with the machine. This wear is particularly promoted by the fact that between the sliding on each other Turning dust reaches surfaces. The use of roles controls this disadvantage also only poorly.

Erfindungsgemäß wird vorgeschlagen, den Stahlhalter als Teil eines Gelenksystems auszubilden. Dadurch kommen die freiliegenden großen Gleitflächen in Fortfall. Die verhältnismäßig kleinen Gleitflächen der Drehbolzen können leicht gegen Verschleiß durch Staub usw. geschützt werden.According to the invention it is proposed to design the steel holder as part of a joint system. This eliminates the large exposed sliding surfaces. The proportionate Small sliding surfaces of the pivot pin can easily be protected against wear from dust etc. are protected.

An sich ist es bekannt, bei Drehbänken zum Bearbeiten unrunder Werkstücke unter Vermittlung von Hebeln den Schneidstahl zu schwenken, doch ist hierbei der Stahlträger um eine feste Achse drehbar derart, daß die Stahlspitze Schwingbewegungen auf einer Kreisbahn ausführt. Demgegenüber erfolgt erfindungsgemäß, wie dies in baulich anderer Art bekannt ist, die Bewegung des Stahls um seine Arbeitsspitze.It is known per se, in lathes for machining non-circular workpieces with intermediation to pivot the cutting steel of levers, but here the steel beam is rotatable about a fixed axis such that the Steel tip performs oscillating movements on a circular path. In contrast, takes place according to the invention, as is known in a structurally different way, the movement of the steel his working tip.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Anwendung bei einer Vierkantblockdrehbank dargestellt.An exemplary embodiment of the subject matter of the invention is used in the drawing shown on a square block lathe.

Das Gelenksystem wird hier gebildet aus den Hebeln 1 und 2, die um feste Drehpunkte 3 und 4 schwenkbar sind. Die Bewegung des unteren Hebels erfolgt unter Vermittlung der auf und ab beweglichen Stange 5, die an dem Hebel 1 angelenkt ist. Die beiden Hebel 1 und 2 sind gelenkig durch die beiden winklig eingebogenen Laschen 6 und 7 verbunden. Diese Laschen 6 und 7 tragen gelenkig den Stahlhalter 8, wobei die Entfernungen der Gelenke 9 und 10 bzw. 11 und 12 von den zugehörigen festen Drehpunkten 3 und 4 den Entfernungen der Gelenkpunkte 13 und 14 von der Stahlspitze 15 entsprechen. Es ist ersichtlich, daß die Punkte 13 und 14 beim Aufundabbewegen der Zugstange 5 Kreisbewegungen ausführen, die den Kreisbewegungen der Punkte 9, 10, 11 und 12 entsprechen, und zwar erfolgt die Kreisbewegung der Punkte 13 und 14 dabei um die Stahlspitze 15. Durch die im Ausführungsbeispiel gezeigte Ausknickung der Laschen 6 und 7 wird die Stahlspitze aus der gemeinsamen Ebene der Drehbolzen 3 und 4 herausgebracht; sie kann auch, wie ohne weiteres ersichtlich, in die genannte Ebene oder wieder aus dieser heraus nach hinten verlegt werden.The joint system is formed here from levers 1 and 2, which are centered around fixed pivot points 3 and 4 are pivotable. The movement of the lower lever takes place under mediation the rod 5 which can move up and down and which is articulated on the lever 1. The two Levers 1 and 2 are articulated by the two angled brackets 6 and 7. These tabs 6 and 7 articulately support the steel holder 8, with the distances of the joints 9 and 10 or 11 and 12 from the associated fixed pivot points 3 and 4, the distances between the pivot points 13 and 14 from the steel tip 15 correspond. It can be seen that points 13 and 14 when the pull rod 5 is moved up and down Perform circular movements that correspond to the circular movements of points 9, 10, 11 and 12, namely, the circular movement of points 13 and 14 takes place around the steel tip 15. The buckling of the tabs 6 and 7 shown in the exemplary embodiment the steel point is brought out of the common plane of the pivot pins 3 and 4; As is readily apparent, it can also be moved into or out of the above-mentioned level moved out to the rear.

Um die Gelenice des Gelenksystems vor äußeren Einflüssen zu schützen, kann, wie ohne weiteres ersichtlich, die Ausbildung so getroffen werden, daß der Stahlhalter aus der Ebene der Hebel ι und 2 herausgebracht und seitlich eines das ganze Lenkersystem einschließenden Gehäuses angeordnet wird.To protect the gelenice of the joint system from external influences, such as readily apparent, the training can be made so that the steel holder from the Level of levers ι and 2 brought out and laterally one enclosing the entire handlebar system Housing is arranged.

Durch die neue Ausbildung der Schwenkeinrichtungwerden die obengenannten Mängel der bisherigen Gleit- bzw. Rollenführungen vermieden.The above-mentioned deficiencies become due to the new design of the pivoting device the previous sliding or roller guides avoided.
