Abstract

Die Erfindung betrifft eine Einrichtung zur Anzeige der Stellung eines Hydraulikzylinders als Stellglied einer Walze­ nanstellung mit einem in einem Zylinder beweglichen Kol­ ben, dessen eine Oberfläche direkt gegen die Lagerstücke des Walzwerkes drückt. Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, die eine höchst genau zuverlässige und repro­ duzierbare Wegmessung des Kolbens ermöglicht. Dazu wird vorgeschlagen, daß die dem Zylinderboden (1) zugewandte Seite des Kolbens (2) mit einem dünnen Rohr (3) verbunden ist, das abgedichtet durch den Zylinderboden (1) geführt ist und daß innerhalb diese Rohres (3) eine Meßstange (4) vorgesehen ist, die einerseits mit dem Kolben (2) und andererseits mit einer dessen Längsbewegung anzeigender Meßeinrichtung (5) verbunden ist. The invention relates to a device for displaying the Position of a hydraulic cylinder as an actuator of a roller Positioning with a piston movable in a cylinder ben, one surface directly against the bearing pieces of the rolling mill presses. The object of the invention is to achieve this based on a facility of the type mentioned at the beginning create the most highly reliable and repro Duceable distance measurement of the piston enables. This will proposed that the cylinder bottom (1) facing Side of the piston (2) connected to a thin tube (3) is, which is sealed through the cylinder base (1) and that within this tube (3) a measuring rod (4) is provided, on the one hand with the piston (2) and on the other hand with a longitudinal movement indicating it Measuring device (5) is connected.
