State of the art
Dans le domaine automobile, il est connu d'implémenter des tuyaux rigides appartenant au système de freinage du véhicule. Classiquement, chaque tuyau rigide métallique subi une opération de cintrage dont le résultat doit faire l'objet d'une opération de contrôle de la géométrie du tuyau rigide. Classiquement, l'opérateur chargé de cette opération utilise une machine de contrôle de géométrie destinée à contrôler la géométrie d'un objet. Cette machine de contrôle comprend une table de contrôle, notamment sous la forme d'un marbre ou bâti métallique, au moins un support maintenu en position sur la table de contrôle et un dispositif de mesure tridimensionnelle sous la forme d'un robot fournissant des informations représentatives de la géométrie de l'objet maintenu sur ledit au moins un support. In the automotive field, it is known to implement rigid pipes belonging to the braking system of the vehicle. Conventionally, each rigid metal pipe undergoes a bending operation, the result of which must be the subject of a control operation of the geometry of the rigid pipe. Conventionally, the operator responsible for this operation uses a geometry control machine for controlling the geometry of an object. This control machine comprises a control table, in particular in the form of a marble or metal frame, at least one support held in position on the control table and a three-dimensional measuring device in the form of a robot providing information. representative of the geometry of the object held on said at least one support.
La problématique repose ici sur la nature et la conception de ces supports. The problem lies here in the nature and design of these supports.
Classiquement, chaque support comprend un pied destiné à être maintenu sur la table de contrôle à un emplacement choisi minutieusement en fonction de la nature de l'objet à supporter et dont la géométrie est à contrôler et une tête sur laquelle l'objet est positionné. Chaque support comprend un moyen de bridage par serrage de l'objet ainsi positionné au niveau de la tête du support. Conventionally, each support comprises a foot intended to be held on the control table at a location selected carefully depending on the nature of the object to be supported and whose geometry is to be controlled and a head on which the object is positioned. Each support comprises clamping means for clamping the object thus positioned at the level of the head of the support.
Il s'avère que la conception d'un tel support est complexe et onéreuse. D'autre part, l'action de serrage génère durant le maintien des contraintes à l'objet susceptibles de provoquer un risque de déformation pouvant induire des erreurs de contrôle et de marquage. Cela peut même conduire à un résultat négatif de l'opération de contrôle en ce sens que l'objet contrôlé est déclaré comme ne pouvant pas être monté sur le véhicule. It turns out that the design of such a support is complex and expensive. On the other hand, the clamping action generates during the maintenance of stresses to the object may cause a risk of deformation may induce control errors and marking. This can even lead to a negative result of the control operation in that the controlled object is declared as not being mountable on the vehicle.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre de modes particuliers de réalisation de l'invention donnés à titre d'exemples non limitatifs et représentés sur les dessins annexés, dans lesquels les figures 1 et 2 sont des vues en coupe verticale d'un exemple de support selon l'invention, respectivement réglé de sorte à présenter des première et deuxième hauteurs différentes. Other advantages and features will emerge more clearly from the following description of particular embodiments of the invention given by way of non-limiting example and shown in the accompanying drawings, in which FIGS. 1 and 2 are views in vertical section of an example of support according to the invention, respectively set to present different first and second heights.
Description de modes préférentiels de l'invention Description of preferred modes of the invention
L'invention décrite ensuite en référence aux figures 1 et 2 concerne un support 10 pour le maintien spatial d'un objet 12 durant une opération de contrôle de géométrie de cet objet 12. Le support 10 comprend à cet effet un élément de positionnement 15 de l'objet 12 sur le support 10. The invention described next with reference to FIGS. 1 and 2 concerns a support 10 for the spatial maintenance of an object 12 during a geometry control operation of this object 12. The support 10 comprises for this purpose a positioning element 15 of the object 12 on the support 10.
Elle concerne aussi, même si elle n'est pas représentée dans son ensemble, une machine de contrôle de géométrie destinée à contrôler la géométrie de l'objet 12. Cette machine de contrôle comprend une table de contrôle 1 1 , au moins un tel support 10 maintenu en position sur la table de contrôle 1 1 , notamment par effet magnétique, et un dispositif de mesure tridimensionnelle (non représenté) fournissant des informations représentatives de la géométrie de l'objet 12 maintenu sur ledit au moins un support 10. It also concerns, even if it is not represented as a whole, a geometry control machine intended to control the geometry of the object 12. This control machine comprises a control table 1 1, at least one such support 10 kept in position on the control table 1 1, in particular by magnetic effect, and a three-dimensional measuring device (not shown) providing information representative of the geometry of the object 12 held on said at least one support 10.
De manière essentielle, le support 10 comprend une première source magnétique S1 générant un premier champ magnétique permettant la création d'une première force d'attraction magnétique F1 appliquée à l'objet 12 en direction de l'élément de positionnement 15, lorsque l'objet 12 est placé dans le premier champ magnétique, et dont l'intensité est telle que la première force d'attraction magnétique F1 maintient en position l'objet 12 sur l'élément de positionnement 15. Essentially, the support 10 comprises a first magnetic source S1 generating a first magnetic field enabling the creation of a first magnetic attraction force F1 applied to the object 12 in the direction of the positioning element 15, when the object 12 is placed in the first magnetic field, and whose intensity is such that the first magnetic attraction force F1 holds the object 12 in position on the positioning element 15.
Une condition de fonctionnement de la solution présentée ici est que l'objet 12 dont la géométrie est à contrôler et destiné à être maintenu en position par l'intermédiaire d'au moins un tel support 10 soit formé dans un matériau ferromagnétique sensible au champ magnétique généré par la première source magnétique S1 . Une application préférentielle, particulièrement visée par l'objet de l'invention (le support 10 et la machine de contrôle) qui est adapté à cette application particulière, concerne le contrôle de la courbure d'un tuyau rigide pour véhicule automobile après une opération de cintrage, notamment un tuyau de système de freinage. An operating condition of the solution presented here is that the object 12 whose geometry is to be controlled and intended to be held in position by means of at least one such support 10 is formed in a ferromagnetic material sensitive to the magnetic field generated by the first magnetic source S1. A preferred application, particularly targeted by the subject of the invention (the support 10 and the control machine) which is adapted to this particular application, concerns the control of the curvature of a rigid pipe for a motor vehicle after an operation of bending, especially a brake system hose.
Toutefois, le domaine d'application n'est pas limité aux seuls tuyaux rigides des systèmes de freinage mais peut au contraire s'étendre à tout type de tuyau rigide, par exemple un tuyau d'échappement des gaz issus du moteur du véhicule, voire même toute pièce en trois dimensions pouvant être maintenue par magnétisme sur le support. La conception du support 10, notamment la taille et la valeur de l'effort d'attraction magnétique F1 à atteindre, tiendra alors compte de la nature de l'objet 12 destiné à être maintenu durant le contrôle de sa géométrie. However, the field of application is not limited to only the rigid pipes of the braking systems but may instead extend to any type of rigid pipe, for example an exhaust pipe of the gases coming from the engine of the vehicle, even even any three-dimensional piece that can be held magnetically on the support. The design of the support 10, in particular the size and the value of the effort of attraction magnetic F1 to achieve, then take into account the nature of the object 12 to be maintained during the control of its geometry.
La première source magnétique S1 comprend de préférence au moins un élément formé dans un matériau magnétique générant en permanence le premier champ magnétique, notamment un aimant permanent 9. The first magnetic source S1 preferably comprises at least one element formed in a magnetic material permanently generating the first magnetic field, in particular a permanent magnet 9.
Alternativement ou en combinaison, la première source magnétique S1 comprend au moins une bobine électrique (non représentée) traversée par un courant électrique de sorte à générer le premier champ magnétique. Alternatively or in combination, the first magnetic source S1 comprises at least one electrical coil (not shown) traversed by an electric current so as to generate the first magnetic field.
Préférentiellement, le support 10 comprend un pied 13 comprenant une base 1 destinée à reposer sur la table de contrôle 1 1 et une tête 14 solidaire du pied 13 à l'opposé de la base 1 selon la direction s'éloignant de la table 1 1 . La tête 14 inclut l'élément de positionnement 15 mentionné précédemment. La première source magnétique S1 est disposée au niveau de la tête 14 afin d'agir sur l'objet 12 de sorte à le maintenir dans sa position sur l'élément de positionnement 15. Plus précisément, par exemple, la face supérieure de l'aimant permanent 9 qui est disposé au niveau de la tête 14 constitue une zone d'appui de l'objet 12 afin de constituer l'élément de positionnement 15. Preferably, the support 10 comprises a foot 13 comprising a base 1 intended to rest on the control table 1 1 and a head 14 integral with the foot 13 opposite the base 1 in the direction away from the table 1 1 . The head 14 includes the aforementioned positioning element 15. The first magnetic source S1 is disposed at the head 14 to act on the object 12 so as to maintain it in its position on the positioning element 15. More precisely, for example, the upper face of the permanent magnet 9 which is disposed at the level of the head 14 constitutes a bearing zone of the object 12 in order to constitute the positioning element 15.
Avantageusement, le support 10 comprend un élément de liaison 8 entre le pied 13 et la tête 14 et conférant une liaison rotule entre le pied 13 et la tête 14 permettant un réglage par rotulage de la position occupée par la tête 14 par rapport au pied 13. Ce mouvement de rotule de la tête 14 par rapport au pied 13 peut être libre afin de permettre une auto-adaptation automatique de la position de la tête 14 en fonction de l'organisation spatiale locale de l'objet 12 maintenu. Toutefois, il peut éventuellement être prévu un élément de blocage (non représenté) variant entre un état déverrouillé et un état verrouillé respectivement dans lesquels l'élément de blocage autorise et interdit le mouvement de rotulage conféré par l'élément de liaison 8. La nature du pied peut être quelconque dès lors qu'elle est adaptée à la fonction recherchée. Toutefois, la structure représentée sur les figures 1 et 2 donne une entière satisfaction en pratique : le pied 1 3 comprend un corps de longueur ajustable permettant un réglage de la hauteur H séparant la tête 14 et la base 1 du pied 1 3. Ce corps peut comprendre un fourreau 2, 3 lié par son extrémité inférieure à la base 1 . Ce fourreau 2, 3 délimite un logement à l'intérieur duquel peut coulisser une tige 4 appartenant au corps, par glissement vertical ou par vissage selon un axe vertical. La longueur du corps est donc ajustée en fonction de la position de la tige 4 par rapport au fourreau 2, 3 et/ou en fonction de la hauteur h1 , h2 intrinsèque du fourreau 2, 3. Plus précisément, dans la variante illustrée, deux fourreaux 2, 3 ayant des hauteurs h1 , h2 différentes peuvent séparément être utilisés et sélectivement assemblés à la base 1 et c'est le choix parmi ces deux fourreaux 2, 3 qui permet de choisir la hauteur H parmi deux valeurs discrètes prédéterminées. Un nombre différent de deux de tels fourreaux de hauteurs différentes peut être prévu. Eventuellement, chaque fourreau peut être télescopique pour permettre d'affiner les possibilités d'ajustement. Advantageously, the support 10 comprises a connecting element 8 between the foot 13 and the head 14 and conferring a ball joint between the foot 13 and the head 14 allowing adjustment by swiveling the position occupied by the head 14 relative to the foot 13 This patella movement of the head 14 relative to the foot 13 may be free to allow automatic self-adaptation of the position of the head 14 according to the local spatial organization of the object 12 maintained. However, it may possibly be provided a blocking element (not shown) varying between a state unlocked and a locked state respectively in which the locking element allows and prohibits the swiveling movement imparted by the connecting element 8. The nature of the foot can be any as soon as it is adapted to the desired function. However, the structure shown in Figures 1 and 2 gives complete satisfaction in practice: the foot 1 3 comprises a body of adjustable length allowing adjustment of the height H between the head 14 and the base 1 of the foot 1 3. This body may comprise a sleeve 2, 3 linked by its lower end to the base 1. This sleeve 2, 3 defines a housing inside which can slide a rod 4 belonging to the body, by vertical sliding or by screwing along a vertical axis. The length of the body is thus adjusted as a function of the position of the rod 4 relative to the sheath 2, 3 and / or as a function of the intrinsic height h1, h2 of the sheath 2, 3. More specifically, in the variant illustrated, two The sleeves 2, 3 having different heights h1, h2 can be separately used and selectively assembled at the base 1 and it is the choice among these two sleeves 2, 3 which allows to choose the height H from two predetermined discrete values. A different number of two such sleeves of different heights can be provided. Optionally, each sleeve can be telescopic to allow to refine the possibilities of adjustment.
L'extrémité supérieure de la tige 4 est fixée, notamment par vissage, à une extrémité inférieure de l'élément de liaison 8 tandis que l'aimant permanent 9 est fixé, notamment par vissage, à une extrémité supérieure de l'élément de liaison 8. Des contre-écrous 7 peuvent être prévus afin de bloquer la position de l'élément de liaison 8 sur la tige 4 et la position de la tige 4 par rapport au fourreau 2, 3. La fixation du fourreau 2, 3 sur la base 1 peut être obtenue par vissage d'une vis 5 traversant la base 1 et en prise dans le fourreau 2, 3. Une rondelle d'appui 6 peut être intercalée entre la base 1 et le fourreau 2, 3. The upper end of the rod 4 is fixed, in particular by screwing, to a lower end of the connecting element 8 while the permanent magnet 9 is fixed, in particular by screwing, to an upper end of the connecting element 8. Counter-nuts 7 may be provided to block the position of the connecting element 8 on the rod 4 and the position of the rod 4 relative to the sleeve 2, 3. The fixing of the sleeve 2, 3 on the base 1 can be obtained by screwing a screw 5 passing through the base 1 and engaged in the sheath 2, 3. A support washer 6 can be interposed between the base 1 and the sheath 2, 3.
Préférentiellement, la base 1 du pied 1 3 comprend une deuxième source magnétique S2 générant un deuxième champ magnétique permettant la création d'une deuxième force d'attraction magnétique F2 appliquée à la table de contrôle 1 1 en direction de la base 1 du pied 13, lorsque la table de contrôle 1 1 est placée dans le deuxième champ magnétique, et dont l'intensité est telle que la deuxième force d'attraction magnétique F2 maintient en position le support 1 0 sur la table de contrôle 1 1 . Preferably, the base 1 of the foot 1 3 comprises a second magnetic source S 2 generating a second magnetic field for the creation of a second magnetic attraction force F 2 applied to the control table 1 1 towards the base 1 of the foot 13 when the control table January 1 is placed in the second magnetic field, and whose intensity is such that the second magnetic attraction force F2 maintains the support 1 0 in position on the control table 1 January.
La deuxième source magnétique S2 peut être de toute nature. Dans le mode de réalisation illustré, elle comprend de préférence au moins un élément formé dans un matériau magnétique générant en permanence le deuxième champ magnétique, notamment un aimant permanent sous la forme d'une couronne ou d'une bague incluse dans la base 1 . The second magnetic source S2 can be of any kind. In the illustrated embodiment, it preferably comprises at least one element formed in a magnetic material permanently generating the second magnetic field, in particular a permanent magnet in the form of a ring or a ring included in the base 1.
A titre d'exemple, la première source S1 est configurée (dimensions et nature du matériau) de sorte à générer une première force d'attraction F1 ayant une intensité comprise entre 30N et 50N. De même, la deuxième source S2 est configurée (dimensions et nature du matériau) de sorte à générer une deuxième force d'attraction F2 ayant une intensité comprise entre 250N et 300N. D'une façon générale, les forces d'attraction sont fonction de la masse des pièces à supporter. By way of example, the first source S1 is configured (dimensions and nature of the material) so as to generate a first attraction force F1 having an intensity of between 30N and 50N. Similarly, the second source S2 is configured (dimensions and nature of the material) so as to generate a second attraction force F2 having an intensity of between 250N and 300N. In general, the attraction forces are a function of the mass of the parts to be supported.
Concernant enfin la machine de contrôle en tant que telle, la face de la table de contrôle 1 1 sur laquelle ledit au moins un support 1 0 repose comprend des repères (non représentés) permettant le positionnement dudit au moins un support 1 0 à des emplacements facilement repérables et permettant en outre une bonne reproductibilité des processus de contrôle. En effet, l'emplacement de chaque support 1 0 durant une opération de contrôle par la machine est très précis et dépend directement de l'objet à contrôler. En particulier, chaque support 10 doit être placé à un emplacement situé en dehors des zones de l'objet 12 à contrôler afin de ne pas gêner l'accès à ces zones pour le dispositif de mesure tridimensionnelle et choisi de sorte à limiter autant que possible les contraintes mécaniques subies par l'objet 12 en raison du maintien par les supports 10. Ces repères, par exemple sous la forme d'un quadrillage formé sur le plan de la face de la table 1 1 destinée au maintien des supports 10, peuvent être constitués par gravure dans la matière de la table 1 1 , par utilisation d'un ruban adhésif ou d'une peinture. Finally, concerning the control machine as such, the face of the control table 1 1 on which said at least one support 1 0 rests comprises markers (not shown) for positioning said at least one support 1 0 at locations easily identifiable and also allowing good reproducibility of the control processes. Indeed, the location of each support 1 0 during a Control operation by the machine is very accurate and depends directly on the object to be controlled. In particular, each support 10 must be placed at a location outside the areas of the object 12 to be controlled so as not to hinder access to these areas for the three-dimensional measuring device and chosen so as to limit as much as possible the mechanical stresses undergone by the object 12 due to the retention by the supports 10. These marks, for example in the form of a grid formed on the plane of the face of the table 1 1 intended to hold the supports 10, can be constituted by etching in the material of the table 1 1, by using an adhesive tape or a paint.
Les avantages sont les suivants : The advantages are:
le support 10 pour le maintien spatial d'un objet 12 durant une opération de contrôle de géométrie dudit objet est simple, économique et facile à utiliser,  the support 10 for the spatial maintenance of an object 12 during a geometry control operation of said object is simple, economical and easy to use,
