Abstract

A position-independent angle measurement device with a digital display enables angles between non-abutting surfaces, e.g. in machines, workpieces and assemblies, of intermediate values to be accurately measured at moderate cost. A pendulam (1) mounted in a housing (5) so as to be free to rotate has a notched disc (2) attached to it whose notch location point coincides with the pendulam rotation axis centre point (3). A corresponding notched disc (4) attached to the housing is aligned with the pendulam disc but at a fixed distance. When the housing is tilted the two discs rotate w.r.t. each other. Their mutual rotation is converted into impulses which are counted to drive digital display. The disc attached to the housing consists of a fluid filled cuvette in which the pendulum is mounted.

Description

Lageunabhängiges Winkelmeßgerät mit digitaler AnzeigePosition-independent angle measuring device with digital display

Es ist als eine der ältesten Techniken bekannt, Plachen und Kanten an Körpern oder auch Fluchtlinien waagerecht auszurichten mit Hilfe der Wasserwaage, Schlauchwaage oder auch Dosenlibelle. Senkrechte Ausrichtung kann mit diesen Instrumenten mit zusätzlicher Hilfe eines 90°-Winkels oder aber mit Hilfe des albekannten Lotes vorgenommen werden.It is known as one of the oldest techniques, paving and edging to align horizontally on bodies or on alignment lines with the help of the spirit level, Hose level or circular level. Vertical alignment can be done with these instruments with the additional help of a 90 ° angle or with the help of the well-known plumb bob be made.

Der nachteil dieser Instrumente liegt darin, daß die Ablesung außerordentlich ungenau ist, und wenn es sich da--rum handelt, Winkel festzustellen, die im Raum zwischen waagerecht und senkrecht liegen, versagen diese Instrumente völlig.The disadvantage of these instruments is that the reading is extraordinary is imprecise, and if it is a question of determining angles that are in space between horizontal and vertical, these instruments fail completely.

Hier werden sogenannte Winkelmesser verwendet, deren Ablesegenauigkeit aber ebenfalls gering ist; und wenn gar - wie es im Easchinen- und Werkzeugbau häufig vorkommt -der Winkel zwischen zwei oder mehreren Flächen, Kanten oder Fluchtlinien gemessen werden soll, die nicht unmittelbar aneinander stoßen , so versagen auch diese Instrumente. Und es wird sodann durch "Abfahren" mit Meßuhren über Berechnung mit Hilfe der Winkelfunktionen der Winkel festgestellt.So-called protractors are used here, their reading accuracy but is also small; and if at all - as is often the case in machine and tool making occurs - the angle between two or more surfaces, edges or lines of flight are to be measured that do not directly abut one another, then also fail these instruments. And it is then calculated by "driving down" with dial gauges determined the angle with the help of the trigonometric functions.

Dies ist ein außerordentlich aufwendiges Verfahren und enthalt in großem NTaHe die gefahr des Irrtums - sei es in Beziehung auf die Ablesung oder in Beziehung auf die Rechnung.This is an extremely complex process and contains in great NTaHe the risk of error - be it in relation to the reading or in relation to the bill.

Lageunabhängiges Winkelusßgerät mit digitaler Anzeige Die vorliegende Erfindung löst die Aufgabe, diese Nachteile zu überwinden durch Anordnung von Bauelementen, wie nachstehend als Ausführungsbeispiel an Hand der Abbildung beschrieben.Position-independent angle measuring device with digital display The present The invention solves the problem of overcoming these disadvantages by arranging components, as described below as an exemplary embodiment using the illustration.

Abbildung 1: Ein Pendel Cli,) trägt eine kreisförmige Scheibe oder einen Ring (2), dessen Kreismittelpunkt mit dem Schwingungmittelpunkt des Pendels (3) zusammenfällt. Parallel zu der kreisförmigen Scheibe oder zu dem Ring befindet sich in bestimmtem fixen Abstand'ein gleiches Bauteil (4), welches mit einem Gehäuse (5) fest verbunden ist. Beide Elemente (2)' und (4) tragen je ein Raster, von denen eines als Emitter oder Reflektor ausgebildet ist, während das andere - vorzugsweise das mit dem Gehäuse verbundene - als Emitter und/oder Sensor auBgebildet ist, welche in an sich bekannter Weise auf elektrischer, elektronischer, magnetischer oder elektro-optischer Basis wirken.Figure 1: A pendulum cli,) carries a circular disc or a ring (2), the center of which corresponds to the center of oscillation of the pendulum (3) coincides. Located parallel to the circular disc or to the ring At a certain fixed distance there is an identical component (4) that has a housing (5) is firmly connected. Both elements (2) 'and (4) each carry a grid of which one is designed as an emitter or reflector, while the other - preferably that which is connected to the housing is designed as an emitter and / or sensor, which in a manner known per se in an electrical, electronic, magnetic or electro-optical manner Work base.

Bei waagerecht er Lage des Gehäuses befinden sich de Raster in der Stellung zueinander, welche auf dem Anzeigegerät (6) die Anzeige 000 ergibt. Bei Schwenkung bzw. Neigung des Gehriuses werden die Raster gegeneinander verschoben, weil durch die Erdanziehung das Pendel senkrecht bleibt, und durch Impuiszählung wird die Anzeige plus oder minus die Gradzahl, in welcher das Gehäuse geschwenkt wird.If the housing is in a horizontal position, the grid is in the Position to each other, which shows the display 000 on the display device (6). at Pivoting or inclining the miter, the grids are shifted against each other, because the pendulum remains vertical because of the gravitational pull, and because of the counting of impulses the display is plus or minus the number of degrees in which the housing is pivoted will.

Das Gehause hat vorzugsweise zwei rechtwinklig zueinander verlaufende Kanten (7), (8) zur Erleichterung der Winkelmessung an vorzugsweise mehr um de Senkrechte herum laufende Flächen o..The housing preferably has two mutually perpendicular Edges (7), (8) to facilitate the angle measurement on preferably more around the vertical surfaces running around or

Lageunabhängiges Winkelmeßgerät mit digitaler Anzeige Es gehört zum Stand der Technik, Nullstellungen in jeder beliebigen Position zu fixieren. Diese Technik ist auch für das hier vorgeschlagene Gerät anzuwenden. Um jedoch die waagerechte bzw. senkrechte position jederzeit eingeben zu können, ist eine Arretiervorrichtung 9 vorgesehen, welche die beiden Raster gegeneinander so fixiert, daß die waagerechte Lage des Gehäuses simuliert wird und die Null-Eingabe nach Ausrasten der Arretiervorrichtung wieder der wirklichen waagerechten Lage entspricht.Position-independent angle measuring device with digital display It is part of the State of the art to fix zero positions in any position. These Technology can also be used for the device proposed here. However, to the horizontal To be able to enter a vertical position at any time is a locking device 9 provided, which fixed the two grids against each other so that the horizontal Position of the housing is simulated and the zero input after disengaging the locking device again corresponds to the real horizontal position.
