Abstract
Description
Die vorliegende Erfindung betrifft eine Positionsmeßvorrichtung mit mindestens einem magnetfeldempfindlichen Sensor und mit mindestens einem Magneten, der insbesondere von einem Magnethalter eingefaßt sein kann, wobei der Magnet oder der Magnethalter an einer Anlagefläche eines Sockels verschieblich gelagert ist.The The present invention relates to a position measuring device with at least a magnetic field-sensitive sensor and with at least one magnet, in particular may be bordered by a magnet holder, wherein the magnet or the magnet holder displaceable on a contact surface of a base is stored.
Ein
derartige Positionsmeßvorrichtung
ist aus der deutschen Offenlegungsschrift
Um eine gleitende Bewegung des Schlittens zu ermöglichen, ist zwischen dem Schlitten und dem Rahmen oder einem Gehäuse eine keilförmige Führung vorgesehen. Die schiefen Ebenen der Führung ermöglichen eine vertikalspielfreie Bewegung des Schlittens. Nachteilig ist, daß der absolute Abstand zwischen dem Magneten und einem innerhalb des Rahmens angeordneten magnetfeldempfindlichen Sensor wesentlich von Maßtoleranzen des Schlittens und der Führung abhängt. Bei kleinem Schlitten und großer Führungsbreite rutscht der Schlitten tiefer in die Führung. Bei großem Schlitten und schmaler Führung ist es umgekehrt; in diesem Fall liegt der Schlitten nicht tief genug in der Führung. Die Höhenlage des Schlittens in der Führung schwankt somit bei jedem Zusammenbau aufgrund von Fertigungstoleranzen.Around allowing a sliding movement of the carriage is between the carriage and the frame or a housing a wedge-shaped guide intended. The inclined levels of the guide allow a vertical play free Movement of the sled. The disadvantage is that the absolute distance between the magnet and a magnetic field sensitive sensor disposed within the frame essential of dimensional tolerances of the Sled and the guide depends. With a small sled and a big one guide width the sledge slips deeper into the lead. With a big sled and narrow leadership is it the other way round? in this case, the carriage is not deep enough in the lead. The altitude of the sled in the lead thus fluctuates with each assembly due to manufacturing tolerances.
Der Abstand zwischen dem Magneten und dem magnetfeldempfindlichen Sensor ist für den Kennlinienverlauf des Sensorsignals von signifikantem Einfluß. Daher ist eine möglichst spielfreie und zugleich toleranzarme Lagerung des Magneten gegenüber dem magnetfeldempfindlichen Sensor erwünscht.Of the Distance between the magnet and the magnetic field-sensitive sensor is for the characteristic curve of the sensor signal of significant influence. Therefore is one possible backlash-free and at the same time low-tolerance mounting of the magnet in relation to the Magnetic field-sensitive sensor desired.
Gleichzeitig wird ein besonders einfacher und kostengünstiger Aufbau angestrebt, was einen Verzicht auf kostenaufwendige magnetleitende Materialien erfordert. Hierdurch wird jedoch das Sensorsignal noch stärker vom Abstand zwischen Magnet und Sensor bestimmt, so daß sich die Anforderungen an eine besonders toleranzarme Führung des Magneten weiter vergrößern.simultaneously a particularly simple and inexpensive construction is sought, which is a waiver of expensive magnetically conductive materials requires. As a result, however, the sensor signal is even stronger from Distance between magnet and sensor determined so that the Requirements for a particularly low-tolerance guidance of the magnet further increase.
Es stellte sich daher die Aufgabe, eine Positionsmeßvorrichtung zu schaffen, die sich sowohl durch einen besonders einfachen und kostengünstigen Aufbau als auch durch eine besonders spielarme und zugleich toleranzarme Magnetführung auszeichnet.It Therefore, the task was to provide a position measuring, the Both by a particularly simple and inexpensive Structure as well as by a low-backlash and at the same time low-tolerance magnetic guide distinguished.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß federnde Elemente vorgesehen sind, die den Magneten oder den Magnethalter gegen die Anlagefläche pressen.These Task is inventively characterized solved, that springy Elements are provided which the magnet or the magnet holder against the contact surface press.
Die erfindungsgemäße Positionsmeßvorrichtung zeichnet sich insbesondere durch eine besonders einfache Führung eines Magneten aus.The Position measuring device according to the invention is characterized in particular by a particularly simple management of a Magnets off.
Vorteilhaft ist es, den Magneten durch einen kunststoffgebundenen Magnetwerkstoff auszubilden, wodurch die Form des Magneten leicht an die Form der Anlageflächen des Sockels anpaßbar ist.Advantageous it is the magnet through a plastic-bonded magnet material form, whereby the shape of the magnet easily adheres to the shape of the contact surfaces the base adaptable is.
Ebenfalls vorteilhaft kann der Magnet auch als einfacher Permanentmagnet ausgeführt sein, der zwar weniger gut formbar, dafür aber besonders kostengünstig ist und sich durch eine hohe spezifische Feldstärke auszeichnet.Also Advantageously, the magnet can also be designed as a simple permanent magnet, which is less malleable, but is particularly cost-effective and is characterized by a high specific field strength.
Die Vorteile der beiden vorgenannten Ausführungen lassen sich weitgehend kombinieren, wenn man als Magneten einen Permanentmagneten vorsieht, der in einen Magnethalter eingesetzt ist. Der Magnethalter kann dabei durch eine einfache Kunststoffumspritzung des Magneten gebildet sein.The Advantages of the two aforementioned embodiments can be largely combine, if you provide a magnet as a permanent magnet, which is inserted in a magnet holder. The magnet holder can thereby formed by a simple plastic extrusion of the magnet be.
Besonders vorteilhaft kann der Magnethalter auch als ein aus Kunststoff gespritzter Hohlkörper ausgebildet sein, in den der Magnet eingesetzt werden kann. Durch Verkleben, Verschweißen oder Verspritzen kann der Magnet, vorzugsweise auch formschlüssig, innerhalb des Hohlkörpers befestigt sein.Especially Advantageously, the magnet holder can also be sprayed as a plastic Hollow body formed be, in which the magnet can be used. By gluing, weld together or splashing, the magnet, preferably also form-fitting, within of the hollow body be attached.
Eine gleitende Lagerung des Magnethalters kann durch einen aus Kunststoff gefertigten Distanzrahmen oder durch ein einfaches Distanzblech erreicht werden, welches vorzugsweise über Rastelemente mit dem Sockel verbunden ist. Durch angeformte federnde Elemente wird ein Vertikalspiel, also eine Beweglichkeit des Magneten oder des Magnethalters senkrecht zu seiner Verschieberichtung wirkungsvoll vermieden. Die federnden Elemente können besonders vorteilhaft als angespritzte oder gestanzte Federzungen ausgeführt sein.A Sliding support of the magnet holder can be made of plastic manufactured spacer frame or by a simple spacer plate can be achieved, which preferably via locking elements with the base connected is. By molded resilient elements is a vertical play, So a mobility of the magnet or the magnet holder vertically effectively avoided to his direction of displacement. The springy Elements can particularly advantageous as molded or stamped spring tongues accomplished be.
Die erfindungsgemäße Positionsmeßvorrichtung kann alternativ zur nachfolgend beschriebenen Ausführung als Wegsensor zur Erfassung von Linearbewegungen auch als ein Drehsensor zur Erfassung von Winkelpositionen ausgebildet sein.The Position measuring device according to the invention can be described as an alternative to the embodiment described below Position sensor for detecting linear movements also as a rotary sensor be formed for detecting angular positions.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen gehen aus den abhängigen Ansprüchen und der nachfolgenden Figurenbeschreibung hervor. Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel der Erfindung dargestellt und näher erläutert.Further advantageous embodiments and further developments are dependent on the dependent claims and the following description of the figure. The following will be with reference to the drawing an embodiment represented and closer to the invention explained.

In weiteren möglichen, hier nicht dargestellten Ausführungen sind die federnden Elemente statt an einem separaten Bauteil, am Magnethalter bzw. dem Magneten, dem Sockel, der Leiterplatte, einem Gehäusedeckel oder einem ähnlichen anderen Teil angeordnet. Durch die Federkraft wird der Magnet stets gegen Anlageflächen oder eine sonstige Führung des Sockels gedrückt, so daß eine toleranzarme und spielfreie Lagerung des Magneten gegenüber dem magnetfeldempfindlichen Sensor gewährleistet ist.In other possible, not shown here are the resilient elements instead of a separate component, on Magnetic holder or the magnet, the base, the circuit board, a housing cover or a similar one other part arranged. By the spring force of the magnet is always against contact surfaces or another guide the base pressed, so that one low-tolerance and backlash-free storage of the magnet over the magnetic field-sensitive sensor is ensured.
