Prüfvorrichtung zur Kontrolle auf Vorhandensein von ferromagnetischen BauteilenTest device for checking for the presence of ferromagnetic components
Die Erfindung betrifft eine Prüfvorrichtung zur Kontrolle auf Vorhandensein von ferromagnetisehen vorzugsweise hülsenförmigen Bauteilen in automatischen Fertigungsanlagen.The invention relates to a testing device for checking for the presence of ferromagnetic, preferably sleeve-shaped components in automatic production systems.
Es ist bekannt, die maschinelle Kontrolle auf Anwesenheit von metallischen Bauteilen mit induktiven Sensoren durchzuführen. Für bestimmte geometrische Formen oder besondere Einbaulagen ist diese Art der Kontrolle nicht anwendbar. Dies betrifft insbesondere hülsenartige Bauteile mit kleinem Innendurchmesser wie Muttern, Distanzhülsen oder dergleichen, die fertigungsbedingt nur an der inneren Mantelfläche dektiert werden dürfen.It is known to carry out machine checks for the presence of metallic components using inductive sensors. This type of check cannot be used for certain geometric shapes or special installation positions. This particularly applies to sleeve-like components with a small inner diameter such as nuts, spacer sleeves or the like, which can only be detected on the inner surface due to the manufacturing process.
Weiterhin ist das Messen magnetischer Größen mittels Hall-Effekt-Vorrichtungen bekannt. Diese dienen aber vorwiegend als Wegaufnehmer (G 94 04 164 U1) oder zur Erfassung von Drehwegen (DE 92 12 159 AD.It is also known to measure magnetic quantities using Hall effect devices. However, these are mainly used as displacement sensors (G 94 04 164 U1) or to record rotary displacements (DE 92 12 159 AD.
Es ist Aufgabe der Erfindung, eine Prüfvorrichtung gemäß Oberbegriff des Schutzanspruches zu schaffen, die vorzugsweise hülsenartige ferromagnetische Bauteile an der Mantelfläche der Bohrung oder des Innendurchmessers mit geringem Aufwand an Bauteilen abfragen kann.It is an object of the invention to provide a testing device according to the preamble of the protection claim, which can preferably interrogate sleeve-like ferromagnetic components on the outer surface of the bore or the inner diameter with little effort on components.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des ersten Schutzanspruches gelöst. Die Merkmale der Unteransprüche sind vorteilhafte Ausgestaltung einzelner Details der Lösung.According to the invention, this object is achieved by the features of the first claim. The features of the subclaims are advantageous embodiments of individual details of the solution.
Durch Unterbringung des Magneten und der Messvorrichtung des magnetischen Feldes in der paramagnetischen Aufnahmevorrich-By accommodating the magnet and the magnetic field measuring device in the paramagnetic recording device,
tung für das zu dedektierende hü L senförmige Bauteil wird sichergestellt, dass das Bauteil an der Verarbeitungsstelle vorhanden sein muss, um ein Steuersignal der Messvorrichtung auslösen zu können. Somit ist ausgeschlossen, dass durch beschädigte induktive Sensoren Störungen hervorgerufen werden können. Die Anordnung des Magneten und des Reed-Kontaktes oder Hall-Sensors in der koaxialen Sackbohrung des Aufnahmebolzens ist eine optimale Nutzung der für die Arbeitsaufgabe notwendigen Vorrichtungselemente, ohne dass zusätzliche Veränderungen erforderlich sind.The device for the sleeve-shaped component to be detected ensures that the component must be present at the processing point in order to be able to trigger a control signal from the measuring device. This excludes the possibility of faults being caused by damaged inductive sensors. The arrangement of the magnet and the reed contact or Hall sensor in the coaxial blind bore of the locating bolt is an optimal use of the device elements required for the work task, without any additional changes being necessary.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel erläutert. In der Zeichnung ist ein schematiseher Querschnitt durch die Prüfvorrichtung dargestellt.The invention is explained using an exemplary embodiment in the drawing. The drawing shows a schematic cross-section through the testing device.
Teile 1 einer Autokarosserie sind mit einer Bohrung 2 versehen, zu denen koaxial ein Zentrierring 3 angeordnet ist. Der Zentrierring 3 nimmt eine Distanzhülse 4 auf. Damit diese lagegerecht in den Zentrierring 3 eingebracht wird, befindet sich in der Montagevorrichtung ein Aufnahmebolzen 5 aus paramagnetischem oder gänzlich unmagnetischem Material, der durch die Bohrung 2 der Teile 1 der Autokarosserie ragt. Der Außendurchmesser des Aufnahmebolzens 5 entspricht dem Innendurchmesser der Distanzhülse 4. Der Aufnahmebolzen 5 ist mit einer koaxialen Sackbohrung 6 versehen, in der am Grund der Sackbohrung 6 ein Permanentmagnet 7 befestigt ist. Dessen einer Pol zeigt zum Grund der Sackbohrung 6 und der andere Pol befindet sich auf der gegenüberliegenden Seite des Permanentmagneten 7. In der Sackbohrung 6 ist mit Abstand vom Permanentmagneten 7 ein Reed-Kontakt 8 angebracht, dessen elektrische Leitungen 9 aus der Sackbohrung 6 herausgeführt und mit der Verfahrensablaufsteuerung verbunden sind. Der Abstand des Reed-Kontaktes 8 zum Permanentmagneten 7 ist so gewählt, dass dieser im Bereich hoher Dichte des Magnetfeldes liegt. Anstelle des Reed-Kontaktes 8 ist auch ein Hall-Sensor verwendbar. Der Permanentmagnet 7 kann durch einen Elektromagneten ersetzt werden.Parts 1 of a car body are provided with a bore 2, to which a centering ring 3 is arranged coaxially. The centering ring 3 accommodates a spacer sleeve 4. In order for this to be correctly positioned in the centering ring 3, the assembly device contains a mounting bolt 5 made of paramagnetic or completely non-magnetic material, which protrudes through the bore 2 of the parts 1 of the car body. The outer diameter of the mounting bolt 5 corresponds to the inner diameter of the spacer sleeve 4. The mounting bolt 5 is provided with a coaxial blind bore 6, in which a permanent magnet 7 is attached to the base of the blind bore 6. One pole of the latter points to the bottom of the blind hole 6 and the other pole is on the opposite side of the permanent magnet 7. A reed contact 8 is fitted in the blind hole 6 at a distance from the permanent magnet 7, the electrical lines 9 of which lead out of the blind hole 6 and are connected to the process control system. The distance between the reed contact 8 and the permanent magnet 7 is selected so that it is in the area of high density of the magnetic field. A Hall sensor can also be used instead of the reed contact 8. The permanent magnet 7 can be replaced by an electromagnet.
Arbeitsweise:How it works:
Ist keine Di stanzhüL se 4 vorhanden, befindet sich der Reed-Kontakt 8 in geschlossenem Zustand. Wird eine Distanzhü I se 4 auf den AufnahmeboLzen 5 geschoben, so entsteht über die ferromagnetische DistanzhüLse 4 (die PermeabiLität der HüLse ist wesentlich größer als 1) ein magnetischer Kurzschluss, der zum öffnen des Reed-Kontaktes 8 führt. Dieses Signal wird in der Verfahrensablaufsteuerung als Bedingung für die Weiterführung der Montagevorgänge benutzt. Diese Art der Prüfung auf Vorhandensein von Bauteilen ist für alle ferromagnetischen Bauteile geeignet.If there is no spacer sleeve 4, the reed contact 8 is in the closed state. If a spacer sleeve 4 is pushed onto the mounting bolt 5, a magnetic short circuit is created via the ferromagnetic spacer sleeve 4 (the permeability of the sleeve is significantly greater than 1), which leads to the reed contact 8 opening. This signal is used in the process control as a condition for continuing the assembly processes. This type of check for the presence of components is suitable for all ferromagnetic components.
