Description

PROCEDE D'ASSEMBLAGE D'UN PAVILLON DE VEHICULE AUTOMOBILE ET MOYENS ASSOCIES METHOD FOR ASSEMBLING A PAVILION OF A MOTOR VEHICLE AND ASSOCIATED MEANS

La présente invention concerne un procédé d'assemblage d'un pavillon de véhicule automobile.The present invention relates to a method of assembling a motor vehicle roof.

Cette invention concerne également les moyens associés à ce procédé, et plus particulièrement un dispositif d'accostage d'un pavillon de véhicule automobile sur un côté de caisse.This invention also relates to the means associated with this method, and more particularly to a device for docking a motor vehicle roof on a body side.

La fixation du pavillon sur un côté de caisse d'un véhicule automobile nécessite une liaison avec un jeu régulier, quasi nul, lorsque ce pavillon est soudobrasé au laser par exemple. Il s'agit en effet de favoriser l'assemblage d'une part, et de proposer au client d'autre part un aspect visuel extérieur irréprochable.Fixing the flag on a side of a motor vehicle requires a connection with a regular game, almost zero, when the flag is laser welded for example. It is indeed to promote the assembly on the one hand, and to offer the customer on the other hand an irreproachable exterior visual appearance.

Selon un mode de réalisation connu, on applique, préalablement au soudage du pavillon sur le côté de caisse, un moyen de pressage qui s'étend de façon continue sur toute la longueur du pavillon. Ce moyen est utilisé pour presser le pavillon et le maintenir en position lors de son soudage sur le côté de caisse. Un inconvénient de ce type de réalisation est qu'il ne compense pas tous les défauts d'accostage rencontrés. Ces défauts, et à titre d'exemple des ondulations, ne sont pas toujours les mêmes sur le pavillon ou sur le côté de caisse, et ne sont pas constantes pour un même élément entre l'avant et l'arrière du véhicule.According to a known embodiment, it is applied, prior to welding the flag on the body side, a pressing means which extends continuously over the entire length of the flag. This means is used to press the horn and hold it in position when welding on the body side. A disadvantage of this type of embodiment is that it does not compensate for all docking faults encountered. These defects, and by way of example of the corrugations, are not always the same on the roof or on the body side, and are not constant for the same element between the front and the rear of the vehicle.

Un des objectifs de l'invention est donc de proposer un procédé d'assemblage et des moyens associés qui permettent un assemblage du pavillon. Selon des contraintes que l'on retrouve invariablement chez les différents constructeurs automobiles, la présente invention se veut également peu coûteuse.One of the objectives of the invention is therefore to propose a method of assembly and associated means that allow assembly of the flag. According to constraints that are invariably found in the various car manufacturers, the present invention is also inexpensive.

Pour répondre à ces différents objectifs, l'invention propose un procédé d'assemblage d'un pavillon de véhicule automobile caractérisé en ce qu'il présente au moins les étapes suivantes :To meet these different objectives, the invention proposes a method of assembling a motor vehicle roof characterized in that it has at least the following steps:

- dans une première étape, le pavillon est mis en place par rapport à au moins un côté de caisse, et des moyens presseurs, liés de façon indépendante à au moins un support référentiel, sont amenés en regard du pavillon; - dans une deuxième étape, un effort est appliqué sur au moins un moyen presseur de sorte que celui-ci génère un effort de pression transversal et/ou vertical sur le pavillon;- In a first step, the flag is set up with respect to at least one side of the box, and pressing means, independently linked to at least one reference support, are brought opposite the flag; in a second step, a force is applied to at least one pressing means so that it generates a transverse and / or vertical pressure force on the roof;

- dans une troisième étape, chaque moyen presseur est immobilisé par rapport au référentiel support, dès que la position ou l'effort souhaité est obtenu ;in a third step, each pressing means is immobilized relative to the support frame, as soon as the desired position or force is obtained;

- dans une quatrième étape, on réalise une solidarisation du pavillon au côté de caisse.in a fourth step, the flag is made integral with the body side.

Selon différentes caractéristiques de la présente invention :According to various features of the present invention:

- lors de la première étape, le pavillon est descendu au contact d'au moins un côté de caisse.- In the first step, the flag is lowered in contact with at least one side of the body.

- lors de la première étape, le pavillon est amené à une position géométrique théorique.- In the first step, the flag is brought to a theoretical geometric position.

- lors de la deuxième étape, un effort est appliqué sur au moins un moyen presseur pour asservir ce moyen presseur en position. - lors de la deuxième étape, un effort est appliqué sur au moins un moyen presseur pour asservir ce moyen presseur en effort.during the second step, a force is applied to at least one pressing means for controlling this pressing means in position. during the second step, a force is applied to at least one pressing means for controlling this pressing means with effort.

- lors de la deuxième étape, un premier effort est appliqué sur au moins un premier moyen presseur pour asservir ce premier moyen presseur en effort et un second effort est appliqué sensiblement simultanément sur au moins un deuxième moyen presseur pour asservir ce deuxième moyen presseur en position.during the second step, a first force is applied to at least one first pressing means for controlling this first pressing means in effort and a second force is applied substantially simultaneously on at least one second pressing means for controlling the second pressing means in position.

- des efforts sont appliqués pour asservir en position les moyens presseurs situés à chaque extrémité du pavillon, et en ce que des efforts sont appliqués pour asservir en position les autres moyens presseurs.- Efforts are applied to slave in position the pressing means located at each end of the roof, and in that efforts are applied to enslave in position the other pressing means.

L'invention vise à protéger également un dispositif d'accostage d'un pavillon de véhicule automobile sur un côté de caisse, du type comprenant un support référentiel qui s'étend sur le pavillon, et des moyens pour appliquer sur le pavillon une pression propre à plaquer ce pavillon sur le côté de caisse, caractérisé en ce que le dispositif comporte une multitude de moyens presseurs liés au support référentiel et indépendants les uns des autres, de sorte que différentes pressions peuvent être appliquées en différents points du pavillon.The invention also aims to protect a docking device of a motor vehicle roof on a body side, of the type comprising a reference support which extends over the roof, and means for applying to the roof a clean pressure to flatten this flag on the body side, characterized in that the device comprises a plurality of pressure means linked to the reference support and independent of each other, so that different pressures can be applied at different points of the flag.

Selon différentes caractéristiques de la présente invention :According to various features of the present invention:

- les moyens presseurs sont positionnés contre une face externe du support référentiel.the pressing means are positioned against an external face of the reference support.

- des moyens de blocage sont prévus pour immobiliser en position les moyens presseurs contre le support référentiel.- Locking means are provided to immobilize in position the pressing means against the reference support.

- les moyens de blocage sont manuels, notamment par vissage. - les moyens de blocage sont automatiques et comprennent un mécanisme anti-retour associé au système de mise sous pression hydraulique ou pneumatique.the locking means are manual, in particular by screwing. the locking means are automatic and comprise a non-return mechanism associated with the hydraulic or pneumatic pressurization system.

- le moyen presseur est avantageusement formé d'un matériau absorbeur thermique. - un moyen de butée est aménagé à l'extrémité d'au moins un moyen presseur, de sorte que cette butée s'étende sensiblement transversalement par rapport au moyen presseur, une première surface du moyen de butée étant en contact permanent avec le pavillon tandis qu'une deuxième surface du moyen de butée entre en contact avec le côté de caisse lorsque le pavillon est descendu d'une valeur correspondant à cette côte d'affleurement.the pressing means is advantageously formed of a heat-absorbing material. an abutment means is arranged at the end of at least one pressing means, such that this abutment extends substantially transversely relative to the pressing means, a first surface of the abutment means being in permanent contact with the flag while than a second surface of the medium stopper comes into contact with the body side when the roof has descended by a value corresponding to this outcropping coast.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:

- la figure 1 est une vue de face des moyens selon un premier mode réalisation de l'invention ;- Figure 1 is a front view of the means according to a first embodiment of the invention;

- la figure 2 est une vue de côté d'un moyen représenté à la figure 2 ;- Figure 2 is a side view of a means shown in Figure 2;

- la figure 3 est une vue de face des moyens selon un second mode de réalisation de l'invention ;FIG. 3 is a front view of the means according to a second embodiment of the invention;

- la figure 4 est une vue de côté d'un moyen représenté à la figure 3 ;- Figure 4 is a side view of a means shown in Figure 3;

Dans la description qui va suivre, on adoptera à titre non limitatif une orientation longitudinale, verticale et transversale selon l'orientation traditionnellement utilisée dans l'automobile et indiquée par le trièdre L, V, T de la figure 1.In the following description, a longitudinal, vertical and transverse orientation will be adopted in a nonlimiting manner according to the orientation conventionally used in the automobile and indicated by the trihedron L, V, T of FIG.

Tel que représenté à la figure 1, un support référentiel 2 est disposé sur une majeure partie de la longueur du pavillon 3. Différents moyens presseurs 4 sont agencés contre ce support référentiel, ces moyens presseurs 4 étant indépendant les uns des autres et pouvant se déplacer verticalement et/ou transversalement le long de la face externe 20 du support référentiel 2. Selon l'invention, ces moyens presseurs 4 doivent générer un effort au moins vertical sur le pavillon 3 pour créer une surface de contact continue avec le côté de caisse. Dans ce but, les moyens presseurs 4 étant positionnés contre la face externe 20 du support référentiel 2, cette face 20 peut présenter une forme inclinée dans un plan transversal et vertical. Ainsi, un effort exercé sur le sommet de l'un des moyens presseurs 4 permet un déplacement du moyen presseur 4 à la fois transversal et vertical, en direction du côté de caisse 6 lorsque le moyen presseur 4 est en appui sur le pavillon 3. Il sera compris que la face externe 20 du support référentiel 2 peut également être verticale et générer ainsi un déplacement uniquement vertical des moyens presseurs 4. Tel que représenté sur les figures, la face externe des moyens presseurs peut présenter une forme inclinée pour permettre le passage des robots de soudage.As represented in FIG. 1, a reference support 2 is disposed over a major part of the length of the horn 3. Various pressing means 4 are arranged against this reference support, these pressing means 4 being independent of one another and being able to move vertically and / or transversely along the outer face 20 of the reference support 2. According to the invention, these pressing means 4 must generate an at least vertical force on the roof 3 to create a continuous contact surface with the body side. For this purpose, the pressing means 4 being positioned against the external face 20 of the reference support 2, this face 20 may have a shape inclined in a transverse and vertical plane. Thus, a force exerted on the top of one of the pressing means 4 allows a displacement of the pressing means 4 both transversely and vertically, towards the body side 6 when the pressing means 4 is resting on the roof 3. It will be understood that the external face 20 of the reference support 2 can also be vertical and thus generate a vertical displacement only of the pressing means 4. As shown in the figures, the outer face of the pressing means may have an inclined shape to allow the passage welding robots.

Des moyens de blocage 8 sont prévus pour immobiliser en position les moyens presseurs 4 contre le support référentiel. Selon un mode opératoire représenté par exemple aux figures 3 et 4, les moyens de blocage 8 peuvent être manuels pour l'utilisation du procédé et des moyens associés pour des véhicules de petite série. Dans ces cas, lorsque chaque moyen presseur 4 a appliqué sur le pavillon 3 l'effort souhaité, un opérateur immobilise le moyen presseur 4 sur le référentiel pavillon 3 par vissage.Blocking means 8 are provided to immobilize in position the pressing means 4 against the reference support. According to a procedure shown for example in Figures 3 and 4, the locking means 8 can be manual for the use of the method and associated means for small series vehicles. In these cases, when each pressing means 4 has applied the desired force to the horn 3, an operator immobilizes the pressing means 4 on the horn reference frame 3 by screwing.

Selon un autre mode opératoire représenté par exemple aux figures 1 et 2, les moyens de blocage 8 peuvent être automatiques et comprendre à titre d'exemple un mécanisme anti-retour associé au système de mise sous pression 10 hydraulique ou pneumatique. Ce type de mécanisme, à cliquets anti-retour par exemple, sera avantageusement utilisé pour les applications de ce procédé à de grandes séries.According to another procedure shown for example in Figures 1 and 2, the locking means 8 may be automatic and include as an example a non-return mechanism associated with the hydraulic or pneumatic pressurization system. This type of mechanism, with non-return ratchets for example, will be advantageously used for applications of this process to large series.

Le fait de présenter une multitude de moyens presseurs 4 indépendants les uns des autres permet d'optimiser l'accostage du pavillon 3 sur le côté de caisse 6. Selon une première variante, une faible pression peut être assurée sur le pavillon 3 par un asservissement en position des moyens presseurs 4. Selon une seconde variante, une faible pression peut être assurée sur le pavillon 3 par un asservissement en effort des moyens presseurs 4. Avantageusement, cette multitude de moyens presseurs 4 permet d'appliquer au même pavillon 3 un asservissement en position et un asservissement en pression, selon les zones du pavillon 3. A titre d'exemple, chaque coin du pavillon 3 peut être asservi en position par rapport au côté de caisse 6, car ces quatre accostages sont les plus exposés au regard des utilisateurs, pendant que le reste du pavillon 3 est asservi en pression.The fact of presenting a multitude of pressure means 4 independent of each other makes it possible to optimize the docking of the flag 3 on the body side 6. According to a first variant, a low pressure can be ensured on the flag 3 by a servo 4. In a second variant, a low pressure can be ensured on the roof 3 by a servocontrol in force of the pressing means 4. Advantageously, this multitude of pressing means 4 allows to apply to the same flag 3 a position control and a pressure control, according to the areas of the flag 3. For example, each corner of the flag 3 can be slaved in position by relative to the body side 6, because these four berths are the most exposed to users, while the rest of the flag 3 is slaved in pressure.

Le moyen presseur 4 est avantageusement formé d'un matériau absorbeur thermique. L'utilisation de ce type de matériau lors d'une opération de soudage laser permet d'absorber la chaleur dégagée par l'opération de soudage du pavillon 3 sur le côté de caisse 6. Le pavillon 3 n'absorbe alors pas cette chaleur et on évite ainsi que le pavillon 3 se déforme.The pressing means 4 is advantageously formed of a heat-absorbing material. The use of this type of material during a laser welding operation makes it possible to absorb the heat generated by the welding operation of the horn 3 on the body side 6. The horn 3 then does not absorb this heat and this prevents the flag 3 from being deformed.

Selon un deuxième mode de réalisation, représenté aux figures 3 et 4, un moyen de butée 12 est aménagé à l'extrémité d'au moins un moyen presseur 4, de sorte que cette butée s'étende sensiblement transversalement par rapport au moyen presseur 4. La présence de cette butée permet de garantir une côte d'affleurement vertical Z entre le pavillon 3 et le côté de caisse 6, une première surface 14 du moyen de butée 12 étant en contact permanent avec le pavillon 3 tandis qu'une deuxième surface 16 du moyen de butée 12 entre en contact avec le côté de caisse 6 lorsque le pavillon 3 est descendu d'une valeur correspondant à cette côte d'affleurement Z. Il sera compris que cette côte d'affleurement Z peut être modifiée en changeant les dimensions du moyen de butée 12, et en particulier la distance entre les deux plans contenant respectivement la première et la deuxième surface 16 d'appui évoquées ci- dessus. Le moyen de butée 12 est positionné sur l'un des moyens presseurs 4, et présente une forme telle que le passage du cordon de soudage n'est pas entravé par ce moyen de butée. A titre d'exemple non représenté, un moyen de butée est positionné sur chaque moyen presseur 4 situé à l'extrémité de l'ensemble, et présente une forme en demi cercle qui dégage le passage du cordon de soudage.According to a second embodiment, represented in FIGS. 3 and 4, an abutment means 12 is arranged at the end of at least one pressing means 4, so that this abutment extends substantially transversely with respect to the pressing means 4. The presence of this abutment makes it possible to guarantee a vertical outcropping coast Z between the horn 3 and the body side 6, a first surface 14 of the abutment means 12 being in permanent contact with the horn 3 while a second surface 16 of the abutment means 12 comes into contact with the body side 6 when the flag 3 is lowered by a value corresponding to this outcropping coast Z. It will be understood that this outcropping coast Z can be modified by changing the dimensions of the abutment means 12, and in particular the distance between the two planes respectively containing the first and second bearing surfaces 16 mentioned above. The abutment means 12 is positioned on one of the pressing means 4, and has a shape such that the passage of the welding bead is not impeded by this abutment means. By way of example not shown, a stop means is positioned on each pressing means 4 located at the end of all, and has a semicircle shape that clears the passage of the welding bead.

Le procédé d'assemblage du pavillon 3 présente au moins les étapes suivantes. Le pavillon 3 est tout d'abord mis en place par rapport au côté de caisse 6. Il sera compris que, sans sortir du contexte de l'invention, ce pavillonThe assembly method of the flag 3 has at least the following steps. The flag 3 is first put in place relative to the cash side 6. It will be understood that, without departing from the context of the invention, this flag

3 peut être descendu au contact du côté de caisse 6, ou être descendu à une position géométrique théorique dans laquelle le pavillon 3 est affleurant au côté de caisse 6, ou encore être descendu légèrement au dessus de cette position théorique pour éviter tout contact initial avec le côté de caisse 6. Les ondulations formées sur le pavillon 3 et le côté de caisse 6 génèrent des contacts ponctuels entre ces deux éléments. Afin de créer un contact sensiblement continu apte à permettre le soudage du pavillon 3 sur le côté de caisse 6, des moyens presseurs 4 sont amenés sur le pavillon 3. Ceux ci sont liés à un support référentiel 2 qui vient s'étendre sur une grande partie du pavillon 3. Un effort est appliqué sur la partie supérieure d'au moins un moyen presseur 4 de sorte que celui-ci génère un effort de pression transversal et/ou vertical sur le pavillon 3 pour plaquer ce pavillon 3 contre le côté de caisse 6. Cet effort est taré de manière à ce que l'on obtienne un contact sans aller jusqu'à une déformation du pavillon visible par l'utilisateur. Chaque moyen presseur 4 est immobilisé par rapport au référentiel support, dès que la position ou l'effort souhaité est obtenu. Il est alors réalisé une opération de soudobrasage pour lier le pavillon 3 au côté de caisse 6. Les moyens presseurs3 can be lowered into contact with the body side 6, or down to a theoretical geometric position in which the flag 3 is flush with the body side 6, or be lowered slightly above this theoretical position to avoid any initial contact with the body side 6. The corrugations formed on the roof 3 and the body side 6 generate point contacts between these two elements. In order to create a substantially continuous contact capable of permitting the welding of the horn 3 on the body side 6, pressing means 4 are brought onto the roof 3. These are connected to a reference support 2 which extends over a large area. part of the flag 3. A force is applied on the upper part of at least one pressing means 4 so that it generates a transverse and / or vertical pressure force on the flag 3 to press this flag 3 against the side of crate 6. This effort is calibrated so that we obtain a contact without going to a distortion of the flag visible by the user. Each pressing means 4 is immobilized relative to the support frame, as soon as the desired position or effort is obtained. It is then performed a brazing operation to bind the flag 3 to the cash side 6. The pressing means

4 sont ensuite relevés avec le référentiel support.4 are then read with the support repository.

L'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple. The invention is in no way limited to the described and illustrated embodiments which have been given by way of example only.
