Abstract
Description
Spanneinrichtung für vorwiegend runde Serien-Prüfteile in Meß- u. Prüfmittel Die Erfindung betrifft eine zentrisch spannende Spanneinrichtung mit hoher Wiederholgenauigkeit für Meß- u. Prüfmittel, bei welchem vorwiegend runde Serien-Prüfteile am Umfang bzw. in der Bohrung mittels Spannkugeln zentriert und gespannt werden, die durch zwei voneinander unabhängig verschiebbaren Zentrierl-onen durch eine Käfighülse auf das eingeführte TeilXgedrückt werden.Clamping device for mainly round series test parts in measuring u. Test means The invention relates to a centrally tensioning clamping device high repeatability for measuring and testing equipment, which is predominantly round Series test parts centered on the circumference or in the bore by means of clamping balls and are clamped by two independently movable centering l-ons be pressed by a cage sleeve on the inserted part X.
Im Bestreben, trotz möglicher größerer Form- u. Lagetoleranzen und daraus resultierenden Abweichungen vom Nennmaß, der zu spannenden Teile eine sehr genaue achs- u. winkelgerechte Positionierung derselben zu erzielen, muß dafür gesorgt werden, daß die beweglichen Zentrierkonen sich spielfrei in Linie mit der gedachten Achse bewegen können und außerdem ein rasches Ein- u. Ausspannen der aufzunehmenden Teile gewährleistet ist.In the endeavor, despite possible larger form and position tolerances and the resulting deviations from the nominal size of the parts to be clamped a very To achieve exact axis and angular positioning of the same must be ensured be that the movable centering cones are free of play in line with the imaginary Axis can move and also a quick clamping and unclamping of the to be recorded Parts is guaranteed.
Es sind in diesem Zusammenhang Einrichtungen bekannt geworden, bei denen starr geführte Spannsegmente durch führende Konen auf das zu spannende Teil gedrückt werden. NebS einem erhöhten Aufwand an komplizierten bauteilen ergibt sich dabei der Nachteil, daß gewi3e Formtoleranzen wie etwa die Konizität einer Welle oder Bohrung in der Aufnahme nicht beherrscht werden und daher eine achsgerechte Positionierung nicht gewährleistet ist.In this context, facilities have become known at which rigidly guided clamping segments through leading cones on the part to be clamped be pressed. In addition to an increased expenditure on complicated components, this also results The disadvantage here is that certain shape tolerances such as the conicity of a shaft or hole in the receptacle cannot be mastered and therefore an axially correct Positioning is not guaranteed.
Demgegenüber wird bei der vorliegenden Erfindung angestrebt, die oftmals unvermeidlichen Formabweichungen der Prüfteile zu kompensieren und damit jederzeit eine achs- u. winkelgerechte Position des eingespannten Teiles mit sehr hoher Wiederholgenauigkeit zu erreichen.In contrast, the present invention aims to often to compensate for unavoidable form deviations of the test parts and thus at any time an axially and angularly correct position of the clamped part with very high repeat accuracy to reach.
In der Zeichnung ist je eine Ausführungsvariante der Erfindung zum Spannen einer Welle und zum Spannen in einer Bohrung dargestellt.In the drawing is a variant of the invention for Clamping a shaft and shown for clamping in a bore.
