Abstract
Description
Bereits auf Fachmessen (z. B. CONTROL Mai 98 Sinsheim, MICROTECNIC April 98 Zürich) wurden mechanisch antastende Meßtaster kleiner Bauart für Mehrkoordinaten-Meßmaschinen vorgestellt, welche optisch mittels einer Kamera ausgewertet werden. Diese Meßtaster bestehen aus einer Glasfaser, an deren einem Ende eine Kugel mit kleinem Durchmesser angebracht ist. An dem anderen Ende wird Licht in die Faser eingespeist, welches zur Beleuchtung der Kugel benötigt wird.Already at trade fairs (e.g. CONTROL May 98 Sinsheim, MICROTECNIC April 98 Zurich) were mechanical small touch probes for Multi-coordinate measuring machines presented which be optically evaluated by means of a camera. These probes consist of a glass fiber, on the a small diameter ball at one end is appropriate. At the other end there is light in the Fiber fed, which is used to illuminate the ball is needed.
Die beleuchtete Kugel ist in der Fokusebene vor der Kamera der Mehrkoordinaten-Meßmaschine angebracht, so daß diese Kugel im Kamerabild scharf abgebildet wird. Mittels dieser Kugel können zu vermessende Gegenstände angetastet werden.The illuminated sphere is in the focus plane in front of the Camera of the multi-coordinate measuring machine attached, see above that this sphere is shown sharply in the camera image. Objects can be measured using this sphere be touched.
Ein Auslenken der Kugel bei einer Antastung wird mittels des Kamerabildes, welches die Kugel scharf abbildet, erkannt und ausgewertet.A deflection of the ball during a probing will by means of the camera image, which makes the sphere sharp maps, recognized and evaluated.
Diese Faser-Meßtaster sind - bedingt durch ihre kugelförmige Tastfläche - nicht in der Lage, bestimmte Unebenheitsformen an Oberflächen genau antasten zu können. Es ist Aufgabe der vorliegenden Erfindung, in solchen Fällen eine verbesserte Antastmöglichkeit zu schaffen. These fiber probes are - due to their spherical button - unable to certain Precisely feel unevenness on surfaces can. It is an object of the present invention in in such cases an improved possibility of probing create.
Die nachfolgend beschriebene Erfindung kann eine deutliche Verbesserung gegenüber der Antastgenauigkeit bereits bekannter Faser-Meßtaster kleinster Bauart bringen:The invention described below can be one significant improvement over the probing accuracy already known fiber probe of the smallest design bring:
Zur Verbesserung der Antastgenauigkeit ist das antastende Element nicht kugelförmig, sondern als flache Scheibe ausgebildet.This is to improve the probing accuracy probing element not spherical, but as flat disc.
