Abstract
Vorrichtung mit einem Trägerkörper (1) und einem Maßstab (3), wobei der Trägerkörper (1) einen den Maßstab (3) aufnehmenden Kanal (2) aufweist, in den der Maßstab (3) stirnseitig in Messrichtung X einführbar ist, wobei der Kanal (2) im Trägerkörper (1) von einer Auflagefläche (A) für den Maßstab (3) und von den Maßstab (3) umgreifenden Falzen (5) mit der Auflagefläche (A) zugewandten Gegenflächen (B) gebildet wird, und wobei die Auflagefläche (A) von zumindest einem Steg (1.1, 1.2) des Trägerkörpers (1) gebildet wird, der in Messrichtung X verläuft und die Auflagefläche (A) mit einer Breite ausgebildet ist, die kleiner ist als die Breite des Maßstabs (3),dadurch gekennzeichnet, dassder Maßstab (3) aus einem Teilungsträger (3.1) und einer Schicht (3.2) aus quer zur Messrichtung X elastischem Material besteht, durch welche der Maßstab (3) in dem Kanal (2) zwischen der Auflagefläche (A) und den Gegenflächen (B) des Trägerkörpers (1) klemmbar ist, und dassdie elastische Schicht (3.2) ein Klebeband ist, welches eine Folie (3.21) und eine die Folie (3.21) am Teilungsträger (3.1) haltende Klebstoffschicht (3.22) aufweist.Device with a support body (1) and a scale (3), the support body (1) having a channel (2) which accommodates the scale (3) and into which the scale (3) can be introduced at the end in the measuring direction X, the channel (2) is formed in the support body (1) by a support surface (A) for the scale (3) and folds (5) encompassing the scale (3) with counter surfaces (B) facing the support surface (A), and the support surface (A) is formed by at least one web (1.1, 1.2) of the carrier body (1) which runs in the measuring direction X and the support surface (A) is formed with a width that is smaller than the width of the scale (3), thereby characterized thatthe scale (3) consists of a graduation carrier (3.1) and a layer (3.2) of elastic material transversely to the measuring direction X, through which the scale (3) in the channel (2) between the support surface (A) and the mating surfaces (B) of the carrier body (1) can be clamped, and that the elastic layer (3.2) is a K is lebeband which has a film (3.21) and an adhesive layer (3.22) holding the film (3.21) on the graduation carrier (3.1).
Description
Die Erfindung betrifft eine Vorrichtung mit einem Trägerkörper und mit einem Maßstab nach dem Oberbegriff des Anspruchs 1.The invention relates to a device with a support body and with a scale according to the preamble of
Eine derartige Anordnung ist in der
Fertigungstechnisch ist es nun schwierig diese maßlichen Anforderungen einzuhalten. Einerseits soll der Maßstab in den Kanal einschiebbar sein, andererseits soll er möglichst spielfrei in dem Kanal gelagert sein, um Schwingungen des Maßstabs im Messbetrieb zu vermeiden.From a manufacturing point of view, it is now difficult to adhere to these dimensional requirements. On the one hand, the scale should be able to be pushed into the channel; on the other hand, it should be mounted in the channel with as little play as possible in order to avoid vibrations of the scale during measurement operation.
Eine Möglichkeit, einen Maßstab in einer Nut eines Trägerkörpers zu befestigen, ist in der
Damit ist zwar eine relativ schwingungsfestes Klemmen des Maßstabs erreichbar, die Konstruktion bedingt aber eine nach oben über die gesamte Messlänge offene Nut und eine Verschiebbarkeit des Maßstabs relativ zum Trägerkörper ist ausgeschlossen.In this way, a relatively vibration-proof clamping of the scale can be achieved, but the construction requires a groove that is open upwards over the entire measuring length and a displaceability of the scale relative to the carrier body is excluded.
Dieses Problem wird gemäß der Erfindung mit einer Vorrichtung gemäß den Merkmalen des Anspruchs 1 gelöst.This problem is solved according to the invention with a device according to the features of
Die Vorteile der Erfindung liegen darin, dass der Maßstab schwingungsfest befestigt werden kann und trotzdem eine Verschiebbarkeit des Maßstabs relativ zum Trägerkörper in Messrichtung gewährleistet ist.The advantages of the invention are that the scale can be fixed in a vibration-proof manner and, nevertheless, displaceability of the scale relative to the carrier body in the measuring direction is guaranteed.
Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous refinements of the invention are given in the dependent claims.
Anhand der Zeichnungen wird die Erfindung mit Hilfe eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail with the aid of an exemplary embodiment on the basis of the drawings.
