Description
Spannfutter, insbesondere für Drehbänke.
Um auch bei Abnutzung des Spannfutters einen genauen Rundlauf des zu bearbeitenden Werkstückes zu erreichen und um den gegebenenfalls notwendigen Austausch der Stahlbacken durch solche aus weicherem Werkstoff zu vermeiden, sind erfindungsgemäß Hilfsbacken vorgesehen, die auf den Spannfutterbacken fest angebracht werden und deren Maul dem Durchmesser des einzuspannenden Werkstückes angepaßt wird.In order to ensure precise concentricity of the to be machined workpiece and to make any necessary Avoid replacing the steel jaws with those made of a softer material According to the invention, auxiliary jaws are provided which are firmly attached to the chuck jaws and whose mouth is adapted to the diameter of the workpiece to be clamped.
Vorzugsweise werden als Hilfsbacken zylinderförmige Scheiben verwendet, die eine zylindrische, der Nasdes jeweiligen Spannfutterbackens angepaßte Bohrung aufweisen, wobei ein Befestigungsmittel, z. B. eine Schraube, den festen Sitz auf dem Spannfutterbacken bewirkt.Cylindrical disks are preferably used as auxiliary jaws, the one cylindrical bore adapted to the nose of the respective chuck jaw have, wherein a fastening means, e.g. B. a screw, the tight fit the chuck jaws.
Die Erfindung ist in der Zeichnung beispielsweise dargestellt. Es zeigen : Fig. 1 eine Ansicht eines Spannfutters für eine Drehbank mit aufgesetzten Hilfsbacken ;' Fig. 2 eine Seitenansicht des Spannfutters ; Fig. 3 eine Ansicht eines Hilfsbackens ; Fig. 4 einen Schnitt nach Linie IV-IV der Fig. 3.The invention is shown in the drawing, for example. It demonstrate : Fig. 1 is a view of a chuck for a lathe with attached auxiliary jaws; ' Fig. 2 is a side view of the chuck; Fig. 3 is a view of an auxiliary jaw; 4 shows a section along line IV-IV of FIG. 3.
An jedem Backen 2 eines Dreibackenspannfutters 1, und zwar an der vorstehenden Nase 3, ist eine zylinderförmige Scheibe 4 mit zylindrischer Bohrung 5 aufgesetzt, die mittels einer Kopfschraube 7 befestigt ist.On each jaw 2 of a three-jaw chuck 1, namely on the protruding nose 3, is a cylindrical disc 4 with a cylindrical bore 5 attached, which is fastened by means of a head screw 7.
Angenommen, durch Abnutzung der Backen 2 und ihrer Verstellvorrichtung
ist ein Rundlauf des zu befestigen-
