Description

Bei der BearbQitung -der - Außgnfläche dunnwandiger Hohlkörper, z. B. Zahnkronen, ist es schwierig, diese Körper sicher zu halten, ohne diese zu deformieren oder die-Bearbeitung zu behindern. Die Erfindung soll hier Abhilfe schafen. When machining the outer surface of thin-walled hollow bodies, e.g. B. dental crowns, it is difficult to hold these bodies securely without deforming them or to hinder processing. The invention is intended to remedy this.

Nach der Erfindung besteht die zum Halten verwendete Vorrichtung aus einer zylindrischen Hülse, in der eine Welle drehbar gelagert ist, deren eines Ende mit einem Betätigungsknopf und deren anderes Ende mit einer Gewindebohrung versehen ist, die zur Aufnahme eines Gewindebolzens dient, an dessen Ende ein der Form des Hohlraums des zu bearbeitenden Werkstücks grob angepaßter Gummikörper zwischen einer festen Scheibe und einer auf dem Gewindebolzen verschiebbaren Scheibe gelagert ist.According to the invention, the device used for holding consists of a cylindrical sleeve in which a shaft is rotatably mounted, one end of which provided with an operating button and the other end with a threaded hole is, which serves to receive a threaded bolt, at the end of the shape of the Cavity of the workpiece to be machined roughly matched rubber body between a fixed disc and a slidable on the threaded bolt disc is mounted.

Ein Ausfüiirungsbeispiel ist in der-Zeichnung dargestellt (Fig. I und 2). In der Hülse a ist die mit einem Betätigungsknopf versehene Welle b drehbar gelagert. Das freie Ende der Welle b weist eine Gewindebohrung auf, in die der Schaft der Halterung a' eines Gummikörpers b' eingeschraubt werden kann. Der Gummikörper b' Iiegt zwischen einer festen Endscheibe der Halterung a' und einer auf dem Schaft der Halterung verschiebbaren Gegenscheibe c'. Der Gummikörper ist auswechselbar, so daß je nach der-Form des Hohlraums des zu bearbcitelllden Werkstücks ein dieser Form' grob angepaßter Gummikörper auf die Halterung aufgesetzt werden kann. Wird das zu bearbeitende Werkstück über den Giummikörper geschoben und die Halterung in die Gewindebohrung der Welle b eingeschraubt, so kann durch Drehen des Betätigungsknopfes der Welle die Halterung angezogen werden, wobei durch den Druck der Gegenscheibe auf den Gummikörper dieser deformiert wird und sich fest gegen die Innenwände des zu bearbeitenden Werkstücks anlegt. An Ausfüiirungsbeispiel is shown in the drawing (Fig. I. and 2). The shaft b provided with an actuating button is rotatable in the sleeve a stored. The free end of the shaft b has a threaded hole into which the shaft the holder a 'of a rubber body b' can be screwed. The rubber body b 'lies between a fixed end plate of the holder a' and one on the shaft the bracket sliding counter disc c '. The rubber body is exchangeable, so that depending on the shape of the cavity of the workpiece to be machined this one Form 'roughly adapted rubber body can be placed on the bracket. Will the workpiece to be processed is pushed over the gium body and the holder screwed into the threaded hole of the shaft b, by turning the operating button of the shaft, the bracket can be tightened by the pressure of the counter disc on the rubber body this is deformed and firmly against the inner walls of the workpiece to be machined.
