Abstract
Variable Spannbacke zum Spannen von zu bearbeitenden, kubischen Werkstücken, mit einer rechteckförmigen Platte (1), vorzugsweise aus einem harten Metall, die eine mit vorstehenden Spitzen (4) gezahnte Fläche aufweist, dadurch gekennzeichnet, daß in einer Längskante der Platte (1) ein schmaler Absatz (2) eingeformt ist, daß die gezahnte Fläche dessen senkrecht nach oben verlaufende Wand bildet, und daß die Spitzen (4) durch wellenförmige Ausformungen (5) gebildet werden, die eine Hinterschneidung (6) aufweisen .Variable clamping jaw for clamping cubic workpieces to be machined, with a rectangular plate (1), preferably made of a hard metal, which has a toothed surface with projecting tips (4), characterized in that in a longitudinal edge of the plate (1) Narrow heel (2) is molded in that the toothed surface forms its vertically upward-extending wall and that the tips (4) are formed by undulating formations (5) which have an undercut (6).
Description
Die vorliegende Erfindung betrifft eine variable Spannbacke zum Spannen von zu bearbeitenden, kubischen Werkstücken gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a variable clamping jaw for clamping cubic to be machined workpieces according to the generic term of claim 1.
Zum spanabhebenden Bearbeiten derartiger Werkstücke müssen sie zwischen zwei Spannbacken eines Schraubstockes oder einer sonstigen Spanneinrichtung eingespannt werden. Dabei besteht ein Problem darin, das Werkstück auf einer möglichst kleinen Fläche einzuspannen, um den Verlust an Material möglichst gering zu halten. Da aber beim festen und präzisen Einspannen sehr große Drücke auf das Werkstück ausgeübt werden müssen, ist bei den bisherigen Schraubstockbacken das Problem aufgetreten, daß während der Bearbeitung das Werkstück von den Backen nach oben herausgedrückt wurde.To machine such workpieces, they must between two jaws of a vice or another Clamping device can be clamped. One problem is the workpiece on the smallest possible area to keep the loss of material as low as possible. There but with firm and precise Clamping very large pressures on the workpiece exercised Need to become, the problem occurred with the previous vice jaws, that during the Machining the workpiece from with the cheeks pushed out has been.

Es ist daher Aufgabe der Erfindung, eine variable Spannbacke der eingangs genannten Art derart weiterzubilden, daß ein Werkstück auf kleinstmöglicher Fläche während der Bearbeitung in der Spannvorrichtung gehalten werden kann.It is therefore an object of the invention to further develop a variable clamping jaw of the type mentioned at the outset, the existence workpiece on the smallest possible area while the processing can be held in the clamping device.
Die Aufgabe wird erfindungsgemäß durch eine Spannbacke gemäß Anspruch 1 gelöst.The object is achieved by a Clamping jaw according to claim 1 solved.
Mit der Spannbacke gemäß der Erfindung wird der wesentliche Vorteil erreicht, daß durch die besondere Ausbildung der mit hinterschnittenen Spitzen versehenen, gezahnten Fläche das Werkstück mit Sicherheit nur in einem sehr schmalen, unteren Bereich gefaßt und festgelegt werden kann.With the jaw according to the invention the main advantage achieved by special training of the toothed surface provided with undercut tips Workpiece with Security only grasped and defined in a very narrow, lower area can be.
Dies wird insbesondere dadurch erreicht, daß die Höhe des Absatzes ca. 1,5 mm bis 3 mm, die Tiefe des Absatzes ca. 6 mm bis 8 mm und der Schnittwinkel der Hinterschneidung ca. 60° beträgt.This is achieved in particular by the fact that the height of the paragraph approx. 1.5 mm to 3 mm, the depth of the heel approx. 6 mm to 8 mm and the cutting angle of the undercut is approximately 60 °.
Gemäß einer besonderen Ausführung kann auch der obere Teil mit der spitz gezahnten Fläche aus Hartmetall bestehen, wobei dieses besonders ausgebildete Hartmetallstück dann in eine normale Metallplatte, beispielsweise aus gehärtetem Stahl od. dgl., eingelassen ist.According to a special version, too the upper part with the pointed toothed surface are made of hard metal, this specially designed piece of hard metal then in a normal metal plate, for example from hardened Steel or the like, is embedded.
Die Metallplatte kann schließlich zur Befestigung und Führung mit zwei Bohrungen versehen sein.The metal plate can eventually be used Attachment and guidance be provided with two holes.
Anhand der Zeichnung soll am Beispiel einer bevorzugten Ausführungs form die variable Spannbacke gemäß der Erfindung näher erläutert werden.Based on the drawing, using the example a preferred embodiment the variable jaw according to the invention are explained in more detail.
