Abstract

For the automatic fitting of a motor vehicle door or flap, the motor vehicle body is automatically measured before fitting, and the necessary fitting position of the component is established in order to control the assembly device fitting the component appropriately. After the component has been fitted, its actual position in relation to the vehicle body is measured again. Correction data for the fitting of the corresponding component of the next vehicle body are obtained from the established position of the fitted component.

Description

Die Erfindung betrifft ein Verfahren zum automatischen Einbau eines Bauteiles einer Kraftfahrzeugkarosserie, insbesondere einer Fahrzeugtür oder Fahrzeugklappe, bei dem vor der Montage des Bauteils die Kraftfahrzeugkaros­ serie automatisch vermessen, danach die erforderliche Einbaulage des Bauteiles festgelegt und eine das Einbau­ teil montierende Montagevorrichtung entsprechend gesteu­ ert wird.The invention relates to a method for automatic Installation of a component of a motor vehicle body, in particular a vehicle door or vehicle flap, at the before the assembly of the component the motor vehicle checks series measured automatically, then the required The installation position of the component is determined and the installation Partly assembling mounting device control accordingly is heard.

Bauteile müssen meist in einer genau festgelegten Posi­ tion zu anderen Bauteilen montiert werden. Bei Kraftfahr­ zeugtüren genügt es beispielsweise nicht, diese vor dem Verschweißen ihrer Scharnierbleche mit der Kraftfahrzeug­ karosserie mit einem Handhabungsgerät stets in die glei­ che Position zu bringen, vielmehr muß man zunächst die Karosserie vermessen und dann die Lage der Kraftfahrzeug­ tür so korrigieren, daß in der Türausnehmung nach allen Seiten hin gleich große Fugen entstehen. Ähnliche Pro­ bleme treten auch bei der Motorhaube, bei Heckklappen und anderen Klappen auf, weil dort ungleich breite Fugen stark auffallen.Components usually have to be in a precisely defined position tion to other components. When driving for example, it is not sufficient to Welding their hinge plates to the motor vehicle body with a handling device always in the same to bring che position, rather you first have to Body measured and then the location of the motor vehicle Correct the door so that in the door recess after all There are joints of equal size on both sides. Similar pro Problems also arise with the bonnet, tailgates and other flaps because there are unevenly wide joints stand out strongly.

Es hat sich gezeigt, daß trotz genauen Vermessens der Kraftfahrzeugkarosserie bislang keine voll befriedigende Paßgenauigkeit bei automatisch eingebauten Kraftfahrzeug­ türen und Klappen zu erreichen ist. Ein nachträgliches Justieren solcher Kraftfahrzeugtüren und Klappen ist je­ doch unerwünscht zeitaufwendig und unterbleibt meist aus Kostengründen. Der Verbraucher und selbst Autotester schließen jedoch meist aus ungleichmäßig breiten Fugen auf eine insgesamt schlechte Fertigungsqualität eines Fahrzeugs.It has been shown that despite precise measurement of the Motor vehicle bodywork so far has not been fully satisfactory Fitting accuracy with automatically installed motor vehicle doors and flaps can be reached. An afterthought Adjusting such motor vehicle doors and flaps is ever but undesirably time-consuming and usually does not occur Cost reasons. The consumer and even car testers but usually close from unevenly wide joints  an overall poor manufacturing quality Vehicle.

Der Erfindung liegt das Problem zugrunde, ein Verfahren zum automatischen Einbau von Kraftfahrzeugtüren und -Klappen zu entwickeln, welches eine möglichst exakte Po­ sitionierung dieser Bauteile in Bezug auf die Kraftfahr­ zeugkarosserie ermöglicht, jedoch mit möglichst geringem Aufwand verwirklicht werden kann.The problem underlying the invention is a method for the automatic installation of motor vehicle doors and - To develop flaps that have the most exact buttocks possible sitioning of these components in relation to the motor vehicle tool body allows, but with as little as possible Effort can be realized.

Dieses Problem wird erfindungsgemäß dadurch gelöst, daß nach der Montage des Einbauteils die tatsächliche Posi­ tion des Bauteils in Bezug auf die Kraftfahrzeugkarosse­ rie erneut gemessen wird und daß aus der ermittelten Po­ sition des eingebauten Bauteils Korrekturdaten für die Montage des entsprechenden Bauteils der nachfolgenden Kraftfahrzeugkarosserie gewonnen werden.This problem is solved according to the invention in that after the installation of the installation part, the actual position tion of the component in relation to the motor vehicle body rie is measured again and that from the determined Po sition of the installed component correction data for the Assembly of the corresponding component of the following Motor vehicle body can be obtained.

Durch eine solche Verfahrensweise kann man nach der Mon­ tage eines Bauteils, beispielsweise infolge von Durchbie­ gungen tragender Bauteile, auftretende Ungenauigkeiten erfassen und mittels der gewonnenen Korrekturwerte si­ cherstellen, daß bei der nächstfolgenden Montage diese Ungenauigkeiten nicht mehr auftreten. Bei dem erfindungs­ gemäßen Verfahren kommt es automatisch zu einer Optimie­ rung der Montagegenauigkeit, ohne daß man die Ursachen für eine Ungenauigkeit der Montage wissen muß. Bei Kraft­ fahrzeugtüren ergibt es sich beispielsweise, daß aufgrund des Gewichtes der Kraftfahrzeugtüren sowohl ihre Schar­ nierarme als auch die diese tragende B-Säule oder C-Säule sich verformen, so daß die Kraftfahrzeugtüre im vorderen Bereich eine tiefere Position einnehmen, als sich bei der Zuführung der Kraftfahrzeugtür ergibt. Bei dem erfin­ dungsgemäßen Verfahren kann man solche Verformungen zunächst abschätzen und einen Vorhaltewert eingeben. Wenn nach der ersten Montage einer Fahrzeugtür durch den sich erfindungsgemäß anschließenden zusätzlichen Meßvorgang herausstellt, daß die Fahrzeugtür noch nicht optimal sitzt, wird diese Abweichung vom Idealwert bei der nächstfolgenden Montage automatisch mit Hilfe der Korrekturwerte aufgehoben. Durch das erfindungsgemäße Verfahren nimmt somit die Montagegenauigkeit von Montage­ vorgang zu Montagevorgang zu. Die automatische Montage­ einrichtung ist somit lernfähig.Such a procedure can be used according to Mon days of a component, for example as a result of sag structural components, inaccuracies that occur capture and si using the correction values obtained make sure that this during the next assembly Inaccuracies no longer occur. In the invention According to the procedure, there is automatically an optimization Installation accuracy without knowing the causes must know for an inaccuracy of assembly. With strength Vehicle doors, for example, result from that the weight of the motor vehicle doors both their flock poor in kidney as well as the B-pillar or C-pillar that supports it deform so that the motor vehicle door in the front Take a lower position than in the area Feeding the motor vehicle door results. With the inventor Process according to the invention can be used for such deformations first estimate and enter a lead value. If after the first installation of a vehicle door through which  additional measuring process according to the invention turns out that the vehicle door is not yet optimal sits, this deviation from the ideal value at the next assembly automatically with the help of Correction values canceled. By the invention The method therefore takes the assembly accuracy away from assembly process to assembly process. Automatic assembly furnishing is therefore capable of learning.

Besonders einfach ist das Verfahren durchführbar, wenn die Vermessung mittels Lasermeßköpfen erfolgt.The method can be carried out particularly easily if the measurement is carried out using laser measuring heads.
