Description
Es ist bekannt, zum Messen der Kreuzverschiebung des Arbeitstisches eines Prüfgerätes, einer Werkzeugmaschine od. dgl. in der Grundplatte und der oberen beweglichen Platte der Kreuzverschiebung je einen Maßstab anzuordnen, die sich in der Grundstellung annähernd in ihren Mitten kreuzen. It is known to measure the cross displacement of the work table a test device, a machine tool or the like in the base plate and the upper movable plate of the cross displacement each to arrange a scale that is in cross the basic position approximately in their centers.
Das Beobachtungssystem xnd die Beleuchtungseinrichtung sind in einer besonderen, zwischen diesen beiden Platten liegenden, gegen die oberste gekreuzt beweglichen Platte untergebracht, wobei die optischen Mittel der Beobachtungseinrichtung derart gestaltet sind, daß sie die Skalen der Maßstäbe in zueinander paralleler Lage in dem Bildfeld des Okulars abbilden. Dort werden entweder beide Teilbilder oder durch Abblenden eines nach dem anderen beobachtet. Wenn nun bei dieser Ausführungsform die Skala des einen Maßstabes durch Abblenden aus dem Gesichtsfeld des Olcuiars verschwindet, ist es, da beide Skalen der Maßstäbe in zueinander paralleler Lage im Okularbild zu stehen kommen; nicht möglich, zu beurteilen, ob diese nun das Maß der Quer- oder der Längsverschiebung anzeigen.The observation system xnd the lighting device are in one special, lying between these two plates, crossed against the top one movable plate housed, the optical means of the observation device are designed in such a way that the scales of the measuring rods are parallel to each other Map the position in the field of view of the eyepiece. There are either both partial images or observed by stopping down one at a time. If now in this embodiment the scale of one yardstick by fading out of the Olcuiar's field of vision disappears, it is because both scales of the measuring rods are in a mutually parallel position come to a halt in the eyepiece image; not possible to judge whether this is the measure show the transverse or longitudinal shift.
Dieser Mangel wird erfindungsgemäß dadurch behoben, daß jede der beiden Blenden eine bestimmte, im Betätigungsfall am Okularbiidfeld sichtbare Markierung erhält, die anzeigt, ob die im Okularbildfeld verbleibende Skala das Maß der Quer- oder der Längsverschiebung darstellt. Die Markierung kann beispielsweise aus einer Schrift »längs« und »quer« oder ähnlich oder auch etwa aus je einem im Okularbildfeltd senkrecht zueinander stehenden Pfeil bestehen, dessen Richtung im Okularbildfeid auf den Maßstabsverlauf im Prüfgerät hinweist. This deficiency is remedied in that each of the Both diaphragms have a specific marking visible on the eyepiece image field when actuated which shows whether the scale remaining in the eyepiece image field corresponds to the or the longitudinal displacement. The marking can for example consist of a Lettering “lengthways” and “across” or similar, or perhaps from one each in the eyepiece image field are perpendicular to each other arrow, whose direction in the Okularbildfeid indicates the course of the scale in the test device.
Damit die Markierung im Okularbiidfeid sichtbar wird, besteht sie zweckmäßigerweise aus einer Ausstanzung des Biendenblechs, die nötigenfalls durch einen durchsichtigen und auch farbigen Werkstoff verdeckt sein kann.So that the marking is visible in the eyepiece image, it exists expediently from a punching of the Biendenblechs, if necessary through a transparent and colored material can be covered.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. I eine mikroskopische Ableseeinrichtung für eine Kreuzverschiebung im Aufriß, Abb. 2 die gleiche Einrichtung in der Aufsicht, Abb. 3 und 4 das Okularbildfeld. In the drawing, the invention is shown in an exemplary embodiment, namely Fig. I shows a microscopic reading device for a cross shift in elevation, Fig. 2 the same device in plan view, Fig. 3 and 4 the eyepiece image field.
Die Maßstäbe I und 2 abbildenden Strahlen werden durch das Prismensystem 3 in einem Strahlengang vereinigt und gelangen über das Prisma 4 in das Okular 5, in dessen Bildfeld beide Maßstäbe in zueinander parallele Lage zu stehen kommen. The scales I and 2 imaging rays are through the prism system 3 combined in a beam path and pass through the prism 4 into the eyepiece 5, in whose field of view both scales come to stand in a mutually parallel position.
Dem Prismensystem zugekehrt liegen die Abdeckblenden 6 und 7, die einen Durchlaß in Pfeilform 8 und 9 aufweisen.Facing the prism system are the cover panels 6 and 7, the 8 and 9 have a passage in the shape of an arrow.
Wird die Blende 7 zugezogen, so wird der Maßstab 2 verdeckt. Im Okularbildfeld IO ist der Maßstab I sichtbar, desgleichen der Pfeil 8 (Abb. 3). If the screen 7 is closed, the scale 2 is covered. In the eyepiece image field The scale I is visible, as is the arrow 8 (Fig. 3).
Die Richtung des letzteren zeigt an, nach welcher Richtung hin der im Bildfeld sichtbare Maßstab im Prüfgerät verläuft. Wird dagegen die Blende 6 zugezogen, so entsteht ein Okularbildfeld nach Abb. 4.The direction of the latter indicates in which direction the The scale visible in the image field runs in the test device. If, on the other hand, the cover 6 is closed, This creates an eyepiece image field as shown in Fig. 4.
Es sind der Pfeil g und der Maßstab 2 sichtbar. Die Richtung des Pfeiles gibt die Richtung des Maßstabes 2 im Prüfgerät wieder.The arrow g and the scale 2 are visible. The direction of the arrow shows the direction of the scale 2 in the test device.
