Description

La présente invention concerne un dispositif de réglage de la position relative de deux parties d'une même pièce, par déformation, à l'aide d'une vis conique, d'une zone intermé­diaire reliant ces deux parties.The present invention relates to a device for adjusting the relative position of two parts of the same part, by deformation, using a conical screw, of an intermediate zone connecting these two parts.

Elle a plus particulièrement pour objet, mais non exclusive­ment, la réalisation d'un tel réglage sur des pièces obte­nues par découpe et, éventuellement, déformation d'une matière en feuille telle qu'une bande de métal.It relates more particularly, but not exclusively, to the realization of such an adjustment on parts obtained by cutting and, possibly, deformation of a sheet material such as a metal strip.

Elle s'applique notamment au montage des bilames utilisés sur des appareils à déclenchement thermique tels que, par exemple, des relais thermiques.It applies in particular to the mounting of bimetallic strips used on devices with thermal release such as, for example, thermal relays.

On sait en effet que dans ce type d'application, le seuil de déclenchement de ces appareils est, entre autres, fonction de la position relative des bilames et des organes de déclenchement qui leur sont associés.We know that in this type of application, the triggering threshold of these devices is, among other things, a function of the relative position of the bimetallic strips and the triggering members associated with them.

Il s'avère que, compte tenu des tolérances de fabrication, il n'est pas possible d'obtenir au montage une précision suffisante pour obtenir dans une même série d'appareils des seuils de déclenchement rigoureusement identiques. C'est la raison pour laquelle il est donc nécessaire d'effectuer, en fin de montage, un réglage en position des bilames. Or, dans l'état actuel de la technique, ce réglage constitue une opération délicate, bien souvent effectuée à la main par un personnel spécialisé. Elle est donc coûteuse en temps et ne se prête pas à des cadences élevées de production de ces appareils.It turns out that, taking into account manufacturing tolerances, it is not possible to obtain sufficient precision during assembly to obtain in the same series of devices strictly identical trigger thresholds. This is the reason why it is therefore necessary to carry out, at the end of assembly, an adjustment in position of the bimetallic strips. However, in the current state of the art, this adjustment constitutes a delicate operation, very often carried out by hand by specialized personnel. It is therefore costly in time and does not lend itself to the high production rates of these devices.

Pour tenter de supprimer ces inconvénients, on a déjà essayé de monter les bilames sur des pièces de tôle présentant une plage de support pouvant se monter sur une partie fixe de l'appareil, par exemple le boîtier, et une plage de fixation sur laquelle est monté le bilame, cette plage de fixation s'étendant normalement à la plage de support, la connexion de cette plage de support à la plage de fixation étant alors réalisée grâce à une plage déformable comprenant un perçage taraudé et une découpe ouverte au niveau d'un premier bord de la pièce et s'étendant jusqu'audit perçage.In an attempt to eliminate these drawbacks, we have already tried to mount bimetal strips on sheet metal parts having a support range that can be mounted on a fixed part of the device, for example the housing, and a fixing range on which is mounted the bimetallic strip, this fixing range normally extending to the support range, the connection of this support range to the fixing range then being effected by means of a deformable range comprising a tapped hole and a cutout open at a first edge of the part and extending up to said drilling.

Le réglage était alors obtenu par le vissage dans le perçage taraudé d'une vis conique de manière à engendrer, par un effet de couple, une torsion de la zone déformable comprise entre le perçage et un deuxième bord de la pièce opposé au susdit premier bord et à provoquer, en conséquence, une rotation de la plage de fixation. En vue de diminuer le couple de vissage nécessaire pour provoquer la susdite torsion, on a également proposé de réduire la largeur de la zone déformable en prévoyant une deuxième découpe dans le deuxième bord, à l'opposé du premier bord.The adjustment was then obtained by screwing a tapered screw into the tapped hole so as to generate, by a torque effect, a torsion of the deformable zone comprised between the hole and a second edge of the part opposite the aforesaid first edge. and to cause, as a result, a rotation of the fixing range. In order to reduce the screwing torque necessary to cause the above-mentioned twist, it has also been proposed to reduce the width of the deformable zone by providing a second cut in the second edge, opposite the first edge.

Toutefois, cette solution présente, elle aussi, un certain nombre d'inconvénients.However, this solution also has a certain number of drawbacks.

En effet, malgré la présence de la deuxième découpe, le couple nécessaire au vissage de la vis conique demeure important et l'on constate en outre un arrachement de métal dû au fait que l'effort exercé par la vis conique n'est appliqué que sur un très petit nombre de filets du perçage et, par suite de la déformation, que sur une très faible partie de leur circonférence.In fact, despite the presence of the second cut, the torque necessary for screwing the conical screw remains high and there is also a metal tearing due to the fact that the force exerted by the conical screw is not applied only on a very small number of threads in the hole and, as a result of deformation, only on a very small part of their circumference.

Un autre inconvénient de cette solution consiste en ce que, pour les raisons qui seront exposées par la suite, les déformations dont fait l'objet la zone déformable à la suite du vissage, ne permettent pas de conserver la planéité de cette zone et provoquent en contraire un flambage de celle-­ci. En conséquence, au lieu d'avoir un mouvement de rotation de la plage de fixation autour d'un axe perpendiculaire à la plage de support, on obtiendra un déplacement gauche, incom­patible avec la fonction de réglage recherchée.Another drawback of this solution consists in that, for the reasons which will be explained below, the deformations of which the deformable zone is subjected following screwing, do not make it possible to preserve the flatness of this zone and cause otherwise a buckling of it. Consequently, instead of having a rotational movement of the fixing range around an axis perpendicular to the support range, a left displacement will be obtained, incompatible with the desired adjustment function.

L'invention a donc plus particulièrement pour but de suppri­mer ces inconvénients.The invention therefore more particularly aims to eliminate these drawbacks.

Elle propose à cet effet, un dispositif du type susdit, apte à effectuer le réglage de la position relative de deux parties d'une même pièce, par déformation à l'aide d'une vis conique, d'une zone intermédiaire reliant ces deux parties, cette zone intermédiaire présentant un perçage taraudé dans lequel peut venir se visser ladite vis et une découpe qui s'étend depuis un premier bord de la pièce jusqu'audit perçage.To this end, it proposes a device of the aforementioned type, capable of adjusting the relative position of two parts of the same part, by deformation using an conical screw, of an intermediate zone connecting these two. parts, this intermediate zone having a tapped hole in which can be screwed said screw and a cutout which extends from a first edge of the part up to said drilling.

Selon l'invention, ce dispositif est plus particulièrement caractérisé en ce que la zone intermédiaire comprend en outre au moins une seconde découpe débouchant dans ledit perçage à l'opposé de la première découpe, et qui délimite avec un deuxième bord de la pièce une région déformable formant charnière, déportée par rapport audit perçage.According to the invention, this device is more particularly characterized in that the intermediate zone also comprises at least one second cut opening into said bore opposite to the first cut, and which delimits with a second edge of the part a region deformable forming a hinge, offset relative to said bore.

Grâce à une telle disposition le bras de levier avec lequel s'exerce l'effort résultant du vissage, sur la région défor­mable, est considérablement accru et peut être ajusté de manière à obtenir la déformation désirée avec un effort de vissage acceptable sur la vis conique.Thanks to such an arrangement, the lever arm with which the force resulting from screwing is exerted on the deformable region is considerably increased and can be adjusted so as to obtain the desired deformation with an acceptable screwing force on the conical screw. .

En outre, la déformation du perçage au cours du vissage est plus appropriée et permet une meilleure coopération des filets.In addition, the deformation of the hole during screwing is more appropriate and allows better cooperation of the threads.

Ainsi, pour ces différentes raisons, on réduit la détériora­tion des filets du perçage taraudé et la formation de copeaux.Thus, for these various reasons, the deterioration of the threads of the tapped hole and the formation of chips are reduced.

Dans le cadre des applications précitées, la susdite pièce peut être obtenue à partir d'une matière en feuille (par exemple une bande de tôle) et comprendre une plage de support dont au moins une partie plane s'étend dans un plan, une plage de fixation dont au moins une deuxième partie s'étend dans ledit plan et une plage déformable qui relie la plage de support à la plage de fixation.In the context of the aforementioned applications, the aforementioned part can be obtained from a sheet material (for example a sheet metal strip) and comprise a support area of which at least one planar part extends in a plane, a range fastening of which at least a second part extends in said plane and a deformable area which connects the support area to the attachment area.

Dans ce cas, pour faire en sorte qu'au cours du vissage la deuxième partie plane demeure dans ledit plan, la plage déformable comprend une région repoussée (ou emboutie) au centre de laquelle est réalisé le perçage taraudé, la profondeur de cette région étant telle que sa partie supé­rieure soit dans le plan de la fibre neutre de la région de la plage déformable qui entoure ledit repoussé.In this case, in order to ensure that during the screwing the second flat part remains in said plane, the deformable range comprises a repelled (or pressed) region at the center of which the tapped drilling is carried out, the depth of this region being such that its upper part is in the plane of the neutral fiber of the region of the deformable range which surrounds said repelled.

Dans ce cas, les forces de déformation engendrées par le vissage s'exerceront selon cette fibre neutre et les défor­mations s'effectueront dans le plan de la plage déformable.In this case, the deformation forces generated by the screwing will be exerted according to this neutral fiber and the deformations will be carried out in the plane of the deformable range.

Il convient de noter que les déformations effectuées sur la plage déformable sont quasiment rémanentes. Ceci ne consti­tue cependant pas un inconvénient du fait que dans la plupart des applications, le réglage doit être effectué en usine et qu'il ne doit plus être modifié par la suite. Il est même souvent nécessaire d'interdire ensuite toute possi­bilité d'accès à ce réglage.It should be noted that the deformations carried out on the deformable range are almost remanent. This is not, however, a drawback since in most applications the setting must be carried out at the factory and must not be changed afterwards. It is even often necessary to then prohibit any possibility of access to this setting.

Pour résoudre ce problème, l'invention propose d'utiliser une vis conique dont la tête est conformée de manière à pouvoir coopérer avec un outil spécifique faisant par exem­ple partie d'un dispositif de réglage automatique mais qui ne puisse pas convenir aux outillages standard disponibles sur le commerce et, en particulier, aux clefs et aux tourne-­vis classiques.To solve this problem, the invention proposes to use a conical screw whose head is shaped so as to ability to cooperate with a specific tool, for example part of an automatic adjustment device but which cannot be suitable for standard tools available on the market and, in particular, for conventional wrenches and screwdrivers.

D'une façon plus précise, cette tête présente une forme cylindrique qui s'étend coaxialement à la vis et dont la surface cylindrique présente trois cannelures axées à 120° l'une de l'autre, et dont les ouvertures présentent une largeur inférieure à la longueur d'un côté de l'hexagone dans lequel la forme cylindrique se trouve inscrite.More precisely, this head has a cylindrical shape which extends coaxially to the screw and whose cylindrical surface has three grooves oriented at 120 ° from one another, and whose openings have a width less than the length of one side of the hexagon in which the cylindrical shape is found.

Le dispositif de réglage représenté sur les figures 1 et 2 est plus particulièrement destiné à permettre un ajustement de l'alignement des bilames d'un relais thermique ou les contacts d'un relais ou d'un contacteur. Il comprend une pièce réalisée par découpe et déformation (pliage) d'une bande métallique, cette pièce comportant plus précisément :
- une plage de support 1 de forme rectangulaire qui s'étend dans un premier plan P₁, cette plage 1 pouvant être équi­pée de moyens de fixation, non représentés, sur une partie fixe, par exemple le boîtier 1a d'un appareil tel qu'un relais thermique ;
- une plage déformable 2 qui prolonge la plage de support dans ledit plan P₁, cette plage dont les caractéristiques seront définies ci-après présentant, à son extrémité située à l'opposé de la plage de support, une bande trans­versale 3 qui s'étend en déport par rapport à ladite plage 1 ; et
- une plage de fixation 5, sur laquelle peut venir par exem­ple se fixer un bilane 4 ou un contact qui s'étend dans un deuxième plan P₂ perpendiculaire au premier P₁.
The adjustment device shown in FIGS. 1 and 2 is more particularly intended to allow an adjustment of the alignment of the bimetallic strips of a thermal relay or the contacts of a relay or of a contactor. It comprises a part produced by cutting and deformation (folding) of a metal strip, this part comprising more precisely:
a support area 1 of rectangular shape which extends in a first plane P₁, this area 1 can be fitted with fixing means, not shown, on a fixed part, for example the housing 1a of an apparatus such as a thermal relay;
a deformable pad 2 which extends the support pad in said plane P₁, this pad whose characteristics will be defined below having, at its end situated opposite the support pad, a transverse strip 3 which extends offset from said range 1; and
- A fixing range 5, which can for example be fixed on a balance sheet 4 or a contact which extends in a second plane P₂ perpendicular to the first P₁.

La plage déformable 2 comprend dans sa partie adjacente à la plage de support 1 un perçage taraudé 7 dans lequel peut venir se visser une vis conique 8, une première fente trans­versale 9 débouchant dans le perçage 7 et s'ouvrant à l'extérieur au niveau du bord latéral 10, une deuxième fente transversale 11, diamétralement opposée à la fente 9, qui débouche dans le perçage 7 et qui occupe une fraction de la distance comprise entre le perçage 7 et le bord latéral 12, et éventuellement une troisième fente 9ʹ pratiquée dans le bord latéral 12, sensiblement au droit des fentes 9 et 11. Les fentes 9 et 11 délimitent dans la plage 2 une zone déformable 13 de largeur réduite, cette zone 13 formant une charnière d'axe perpendiculaire au plan P₁ de la plage de support 1.The deformable pad 2 comprises, in its part adjacent to the support pad 1, a threaded bore 7 into which a conical screw 8 can be screwed, a first transverse slot 9 opening into the bore 7 and opening to the outside at the level from the side edge 10, a second transverse slot 11, diametrically opposite to the slot 9, which opens into the bore 7 and which occupies a fraction of the distance between the bore 7 and the side edge 12, and possibly a third slot 9ʹ made in the lateral edge 12, substantially in line with the slots 9 and 11. The slots 9 and 11 delimit in the area 2 a deformable area 13 of reduced width, this area 13 forming a hinge with an axis perpendicular to the plane P₁ of the support area 1.

En position initiale, la vis conique 8 peut se monter à la main et dépasser à peine du perçage 7, de façon à amorcer la prise des filets de la vis 8 avec les filets du perçage 7 proches de la face située côté engagement. Le réglage s'obtient ensuite par un vissage de cette vis 8 qui, par effet de coin, provoque la déformation de la zone 13, entraînant l'ouverture des fentes 9 et 11 et une rotation selon la flèche f de la plage de fixation 5 ainsi d'ailleurs que de la zone de la plage déformable 2 qui lui est adjacen­te.In the initial position, the conical screw 8 can be mounted by hand and barely protrude from the bore 7, so as to initiate the grip of the threads of the screw 8 with the threads of the bore 7 close to the face located on the engagement side. The adjustment is then obtained by a screwing of this screw 8 which, by wedge effect, causes the deformation of the zone 13, causing the opening of the slots 9 and 11 and a rotation according to the arrow f of the fixing range 5 as well as that of the zone of the deformable area 2 which is adjacent to it.

On constate notamment que grâce à la structure précédemment décrite, ce déplacement de la plage de fixation 5 s'effectue perpendiculairement à l'axe de la vis 8. Par ailleurs, la conservation dans le temps du réglage est garantie grâce au fait que la vis 8 est autoblocante et que la déformation rémanente obtenue n'empêche pas l'exercice d'une force élastique résiduelle concourant au développement d'un couple de serrage.In particular, it can be seen that, thanks to the structure described above, this movement of the fixing range 5 is carried out perpendicular to the axis of the screw 8. Furthermore, the preservation over time of the adjustment is guaranteed thanks to the fact that the screw 8 is self-locking and that the residual deformation obtained does not prevent the exercise of a residual elastic force contributing to the development of a tightening torque.

Il s'avère qu'un dispositif du type de celui précédemment décrit souffre cependant d'un inconvénient qui se trouve illustré sur la figure 3.It turns out that a device of the type described above suffers from a drawback which is illustrated in FIG. 3.

En effet, la vis 8 étant conique et le trou 7 cylindrique, ladite vis 8 ne sera en contact avec la plage déformable que par l'arête 15 du perçage 7 situé côté engagement. Ainsi, lorsque l'on serre la vis 8, elle exerce sur la pièce des forces F appliquées sur l'arête 15 du trou 7 qui engendrent un moment de déformation vis-à-vis de la fibre neutre N₁, ce qui contribue à effectuer un déplacement relatif des régions R₁ et R₂ de la plage de déformation 2, non pas dans le plan P₁ mais vers des positions 16, 17 représentées en traits interrompus.Indeed, the screw 8 being conical and the hole 7 cylindrical, said screw 8 will only be in contact with the deformable area by the edge 15 of the bore 7 located on the engagement side. Thus, when the screw 8 is tightened, it exerts on the workpiece forces F applied to the edge 15 of the hole 7 which generate a moment of deformation with respect to the neutral fiber N₁, which contributes to effect a relative displacement of the regions R₁ and R₂ of the range of deformation 2, not in the plane P₁ but towards positions 16, 17 shown in broken lines.

Il est clair que pour éviter ces déformations, il convien­drait de faire en sorte que les forces F soient exercées dans l'axe de la fibre neutre N₁.It is clear that to avoid these deformations, it would be necessary to ensure that the forces F are exerted in the axis of the neutral fiber N₁.

La solution illustrée sur la figure 4 permet d'obtenir kce résultat.The solution illustrated in FIG. 4 makes it possible to obtain this result.

Elle consiste à réaliser au niveau du perçage 7 une région repoussée ou emboutie 16 agencée de telle manière que sa face intérieure 17 soit dans le prolongement de la fibre neutre N₂, de sorte que les forces de déformation s'exerce­ront selon la fibre neutre N₂ et que les déformations de la plage 2 se feront dans son plan. Il s'ensuit que pour obte­nir un tel résultat, la région repoussée 16 doit avoir théoriquement une profondeur égale à la demi épaisseur e du métal.It consists in producing, at the level of the bore 7, a repelled or stamped region 16 arranged in such a way that its inner face 17 is in line with the neutral fiber N₂, so that the deformation forces will be exerted according to the neutral fiber N₂ and that the deformations of range 2 will be in its plane. It follows that to obtain such a result, the repelled region 16 must theoretically have a depth equal to the half thickness e of the metal.

En réalité, la vis 8 refoule un peu de métal et la partie en prise réelle n'est pas limitée à l'arête théorique 18, mais avec l'expérience, on ajuste la profondeur de la région repoussée 16 pour que le plan de la fibre neutre N₂ passe par la partie médiane de la portée réelle. Par ailleurs, la région repoussée 16 ne doit pas gêner la déformation de la zone déformable. A cet effet, la fente 11 doit sortir de cette région, comme cela est visible sur la figure 5.In reality, the screw 8 pushes back a little metal and the part in real engagement is not limited to the theoretical edge 18, but with experience, the depth of the repelled region 16 is adjusted so that the plane of the neutral fiber N₂ passes through the middle part of the real span. Furthermore, the repelled region 16 must not hinder the deformation of the deformable zone. To this end, the slot 11 must come out of this region, as can be seen in FIG. 5.

Bien entendu, la dimension des pièces, la zone déformable, la force F fournie par la vis conique 8, la pente de cette dernière et le bras de levier 1, sont adaptés pour avoir la déformation désirée avec un effort d'action acceptable sur la vis 8.Of course, the size of the parts, the deformable zone, the force F provided by the conical screw 8, the slope of the latter and the lever arm 1, are adapted to have the desired deformation with an acceptable action force on the screw 8.

Bien entendu, l'invention ne se limite pas au mode d'exécu­tion précédemment décrit. Ainsi, par exemple, il serait possible de prévoir au lieu de la fente 11 plusieurs autres fentes convenablement agencées.Of course, the invention is not limited to the embodiment described above. So, for example, it would possible to provide instead of the slot 11 several other slots suitably arranged.

Avec référence aux figures 6 et 7, la vis conique inviolable utilisable dans les dispositifs précédemment décrits comprend une tête sensiblement cylindrique 19 coaxiale à sa partie filetée 20. La surface cylindrique de cette tête 19 comprend trois cannelures axiales 21, 22, 23, à 120° l'une de l'autre, prévues pour recevoir trois crabots correspon­dants 24, 25, 26 d'un outil de vissage dont seulement la tête 27 a été représentée.With reference to FIGS. 6 and 7, the tamper-proof conical screw usable in the devices described above comprises a substantially cylindrical head 19 coaxial with its threaded portion 20. The cylindrical surface of this head 19 comprises three axial grooves 21, 22, 23, at 120 ° one from the other, designed to receive three corresponding dogs 24, 25, 26 of a screwing tool of which only the head 27 has been shown.

Pour éviter qu'elles ne puissent servir de prise à un outil classique de vissage tel qu'une clef plate ou à oeillet, ces cannelures 21, 22 et 23 présentent, au niveau de la surface cylindrique, une largeur l₂ inférieure à celle d'un côté c de l'hexagone 28 dans lequel est inscrite la tête cylindri­que 19.To prevent them from being used as a grip for a conventional screwing tool such as a flat or eyelet wrench, these grooves 21, 22 and 23 have, at the level of the cylindrical surface, a width l₂ less than that of one side c of hexagon 28 in which the cylindrical head 19 is inscribed.

Il est clair que grâce à une telle disposition, le vissage ou le dévissage de la vis sera rendu impossible si l'on ne dispose pas d'un outil spécialement conçu à cet effet.It is clear that thanks to such an arrangement, the screwing or unscrewing of the screw will be made impossible if one does not have a tool specially designed for this purpose.

Ainsi qu'on peut le voir à la figure 8, le dispositif selon l'invention n'est pas limité par la présence de deux fentes alignées aboutissant à l'ouverture cylindrique 7a recevant la vis de réglage ; sur cette figure, deux fentes auxiliai­res 11a, 11b sont placées sensiblement de façon convergente vers une fente débouchante 9a qui se trouve elle-même, éventuellement, dans le prolongement d'une fente opposée 9ʺ. Dans cette variate, il existe deux régions déformables 13a, 13b.As can be seen in Figure 8, the device according to the invention is not limited by the presence of two aligned slots leading to the cylindrical opening 7a receiving the adjusting screw; in this figure, two auxiliary slots 11a, 11b are placed substantially convergently towards a through slot 9a which is itself, possibly, in the extension of an opposite slot 9ʺ. In this variate, there are two deformable regions 13a, 13b.
