Description
Dispositif d'accouplement et de verrouillage automatique de deux tubes coaxiaux
Lorsque l'on désire assembler et verrouiller deux tubes à emmancher l'un dans L'autre, on utilise fréquemment un "montage à baSonnette". Device for automatic coupling and locking of two coaxial tubes
When it is desired to assemble and lock two tubes to be fitted one into the other, a "bayonet mount" is frequently used.
L'un des tubes porte un bossage, tel qu'un ergot cylindrique, faisant radialement saillie, par rapport à L'une de ses surfaces d'extrémité, intérieure ou extérieure. L'autre tube présente une rainure en L dont L'une des branches est disposée dans un plan diamétral longitudinal du tube et débouche sur la face terminale de celui-ci. L'autre branche de la rainure est transversale et son extrémité éloignée de la branche longitudinale est fermée. One of the tubes carries a boss, such as a cylindrical lug, projecting radially, relative to one of its end surfaces, interior or exterior. The other tube has an L-shaped groove, one of the branches of which is arranged in a longitudinal diametral plane of the tube and opens onto the terminal face of the latter. The other branch of the groove is transverse and its end remote from the longitudinal branch is closed.
Dans ce type d'assemblage, Les deux tubes sont emmanchés
L'un dans L'autre, le bossage ayant été préalablement disposé en regard de l'ouverture de la rainure sur la face terminale du tube qui la porte. Lorsque le bossage a parcouru la branche longitudinale de la rainure, une rotation relative des deux tubes permet d'engager le bossage dans la branche transversale de la rainure, ce qui assure le verrouillage de l'accouplement
L'une des applications Les plus connues de ce "montageà baïonnette" est La fixation des ampoules d'éclairage sur Les douilles équipées de contacts mobiles électriques. Dans d'autres applications, Les tubes à accoupler ont des parois épaisses, de sorte que la rainure en L peut être ménagée dans la paroi du tube intérieur, tandis que le bossage fait saillie sur la face interne du tube extérieur.In this type of assembly, the two tubes are fitted
One in the other, the boss having been previously disposed opposite the opening of the groove on the end face of the tube which carries it. When the boss has traversed the longitudinal branch of the groove, a relative rotation of the two tubes makes it possible to engage the boss in the transverse branch of the groove, which ensures the locking of the coupling
One of the best known applications of this "bayonet mount" is the attachment of light bulbs to sockets fitted with mobile electrical contacts. In other applications, the tubes to be coupled have thick walls, so that the L-shaped groove can be made in the wall of the inner tube, while the boss protrudes from the inner face of the outer tube.
Dans certaines industries, notamment dans la construction automobile, on a besoin de réaliser automatiquement le verrouillage de l'accouplement de deux tubes coaxiaux, emmanchés l'un dans
L'autre au moyen d'un robot. On sait que ce genre de machine peut facilement effectuer une translation, mais qu'il est généralement compliqué d'y associer une rotation. Dans le cas particulier de l'accouplement des tubes, cet inconvénient des robots a, jusqu'à présent, freiné leur emploi, puisqu'ils ne peuvent assurer le verrouillage de l'accouplement après L'emmanchement des tubes. In certain industries, in particular in the automobile industry, it is necessary to carry out automatically the locking of the coupling of two coaxial tubes, fitted one in
The other by means of a robot. We know that this kind of machine can easily translate, but that it is generally complicated to associate rotation with it. In the particular case of the coupling of the tubes, this drawback of the robots has, until now, slowed down their use, since they cannot ensure the locking of the coupling after the fitting of the tubes.
La présente invention a donc pour objet un dispositif permettant l'accouplement et le verrouillage automatique de deux tubes coaxiaux au cours de leur emmanchement, Les extrémités en regard des deux tubes étant pourvues des éléments, rappelés plus haut, constituant un "montage à baïonnette". The present invention therefore relates to a device allowing the automatic coupling and locking of two coaxial tubes during their fitting, the opposite ends of the two tubes being provided with the elements, recalled above, constituting a "bayonet mount" .
Selon L'invention, sur le tube portant La rainure en L, est montée une butée transversalement escamotable contre L'action d'un organe élastique. According to the invention, on the tube carrying the L-shaped groove, is mounted a transversely retractable stop against the action of an elastic member.
Cette butée peut évoluer entre, d'une part, sa position de repos, dans laquelle elle est transversalement en regard de
L'entrée de la branche transversale de La rainure, et, d'autre part, une position plus éloignée de L'extrémité fermée de la branche transversale. La butée présente, d'une part, une première portion située sensiblement dans un plan diamétral longitudinal du tube sur lequel elle est montée, cette première portion étant susceptible de venir en prise avec le bossage prévu sur L'autre tube, Lorsque ce bossage est engagé dans la branche transversale de la rainure. La butée présente, d'autre part, une deuxième portion, coudée par rapport à la première, constituant une rampe d'appui transversal pour le bossage, au cours de son dépLacement dans la branche longitudinale de la rainure.This stop can change between, on the one hand, its rest position, in which it is transversely opposite
The entrance to the transverse branch of the groove, and, on the other hand, a position further from the closed end of the transverse branch. The stop has, on the one hand, a first portion located substantially in a longitudinal diametral plane of the tube on which it is mounted, this first portion being capable of engaging with the boss provided on the other tube, When this boss is engaged in the transverse branch of the groove. The stop has, on the other hand, a second portion, bent relative to the first, constituting a transverse support ramp for the boss, during its displacement in the longitudinal branch of the groove.
Grâce à ces dispositions, le verrouillage de l'accouple- ment des deux tubes s'effectue automatiquement au cours de la translation qui provoque leur emmanchement, sans qu'il soit nécessaire de prévoir une opération particulière pour obtenir la rotation relative des deux tubes. Thanks to these provisions, the coupling of the two tubes is locked automatically during the translation which causes them to be fitted, without it being necessary to provide for a particular operation in order to obtain the relative rotation of the two tubes.
L'invention sera mieux comprise et diverses caractéristiques secondaires ainsi que ses avantages apparaîtront au cours de la description qui va suivre, d'un mode de réalisation avantageux, en référence au dessin annexé dans lequel
Les figures la et lb sont des vues schématiques en perspective des extrémités de deux tubes pourvus des éléments constituant un "montage à baïonnette", la butée escamotable selon
L'invention étant supposée enlevée.The invention will be better understood and various secondary characteristics as well as its advantages will appear during the following description, of an advantageous embodiment, with reference to the appended drawing in which
Figures la and lb are schematic perspective views of the ends of two tubes provided with elements constituting a "bayonet mount", the retractable stop according to
The invention being assumed to have been withdrawn.
Les figures 2, 3, 4 et 5 sont des vues partielles développées de la face interne du tube extérieur portant la rainure, dans la région de cette dernière, et montrant Les diverses phases du verrouillage. Figures 2, 3, 4 and 5 are partial developed views of the inner face of the outer tube carrying the groove, in the region of the latter, and showing the various phases of locking.
La figure 6 est une vue partielle développée analogue à la figure 2 dans Le cas d'une variante avantageuse de réalisation.~
Si l'on se reporte tout d'abord aux figures la et lb, on voit L'extrémité d'un tube intérieur A destiné à être emmanché dans un tube extérieur B. La paroi des tubes est relativement épaisse mais cette particuLarité n'est aucunement imposée par L'invention ainsi qu'on s'en rendra compte dans ce qui suit.Figure 6 is a partial developed view similar to Figure 2 in the case of an advantageous alternative embodiment. ~
If we refer first to Figures la and lb, we see the end of an inner tube A intended to be fitted into an outer tube B. The wall of the tubes is relatively thick but this particularity is not in no way imposed by the invention as will be seen in the following.
Le tube intérieur A porte au moins un ergot 1, de préférence cylindrique, faisant radialement saillie par rapport à la face externe du tube. Le tube extérieur B présente dans sa paroi au moins une rainure 2 en L, dont la branche 2a est disposée longitudinalement et débouche sur la face terminale 3 du tube. La branche 2b de la rainure est eLLe-même disposée transversalement. Pour des raisons qui apparaîtront plus loin, la branche 2b a une longueur au moins égale au diamètre de L'ergot 1 et son extrémité 2c opposée à la branche 2a est fermée. The inner tube A carries at least one lug 1, preferably cylindrical, projecting radially from the outer face of the tube. The outer tube B has in its wall at least one groove 2 in L, the branch 2a of which is arranged longitudinally and opens onto the end face 3 of the tube. The branch 2b of the groove is itself arranged transversely. For reasons which will appear later, the branch 2b has a length at least equal to the diameter of the lug 1 and its end 2c opposite the branch 2a is closed.
Bien que, dans la réaLisation décrite et représentée, la paroi du tube extérieur B ait une épaisseur supérieure à la profondeur de la rainure 2, cette condition n'est aucunement imposée par
L'invention ; La rainure 2 pourrait, ainsi que cela est déjà connu, être ménagée sur toute l'épaisseur de la paroi du tube B.Although, in the embodiment described and shown, the wall of the outer tube B has a thickness greater than the depth of the groove 2, this condition is in no way imposed by
The invention; The groove 2 could, as is already known, be formed over the entire thickness of the wall of the tube B.
L'ensemble de L'ergot 1 et de la rainure 2 constitue ce que l'on appelle un "montage à baïonnette" ; en général, il sera avantageux de prévoir deux ou plusieurs ergots régulièrement disposés sur l'un des tubes et des rainures en nombre correspondant sur L'autre tube. D'autre part, ainsi qu'on le sait, Les ergots et
Les rainures peuvent être indifféremment disposés sur le tube extérieur ou sur le tube intérieur sans que cela nuise à l'effica- cité du "montage à baïonnette".The assembly of the lug 1 and the groove 2 constitutes what is called a "bayonet mounting"; in general, it will be advantageous to provide two or more pins regularly disposed on one of the tubes and corresponding number of grooves on the other tube. On the other hand, as we know, Les ergots et
The grooves can be arranged either on the outer tube or on the inner tube without affecting the efficiency of the "bayonet mount".
Si l'on se reporte maintenant à la figure 2, on voit que dans la rainure 2, au voisinage de la zone de raccordement de ses deux branches 2a et 2b, est montée une butée escamotable 4. If we now refer to FIG. 2, we see that in the groove 2, in the vicinity of the connection zone of its two branches 2a and 2b, a retractable stop 4 is mounted.
Cette butée présente une première portion 4a qui, dans la position dite de repos visible sur la figure 2, est située sensi blement dans un plan diamétral longitudinal du tube B et obture pratiquement L'entrée de La branche transversale 2b de la rainure. This stop has a first portion 4a which, in the so-called rest position visible in FIG. 2, is located substantially in a longitudinal diametral plane of the tube B and practically blocks the entry of the transverse branch 2b of the groove.
La portion 4a est prolongée, dans la branche longitudinale 2a, par une portion coudée 4b.The portion 4a is extended, in the longitudinal branch 2a, by a bent portion 4b.
La butée 4 constitue donc un obstable dans la branche longitudinale 2a, mais elle peut être escamotée transversalement, pour libérer toute la largeur de la branche longitudinale 2a. A cet effet, outre d'éventuels moyens de guidage non représentés, la branche longitudinale 2a présente sur sa face opposée à la branche transversale 2b un logement 2d susceptible de recevoir la butée 4. The stop 4 therefore constitutes an obstacle in the longitudinal branch 2a, but it can be retracted transversely, to release the entire width of the longitudinal branch 2a. To this end, in addition to any guide means not shown, the longitudinal branch 2a has on its face opposite to the transverse branch 2b a housing 2d capable of receiving the stop 4.
Un organe élastique, tel qu'un ressort 5, est disposé transversalement dans le logement 2d et prend appui sur la portion 4a de La butée 4.An elastic member, such as a spring 5, is arranged transversely in the housing 2d and bears on the portion 4a of the stop 4.
L'accouplement et le verrouillage automatique des tubes A et B s'effectuent de La façon suivante. En supposant que le tube A est fixe, on amène le tube B vers lui par une translation, suivant la flèche F de La figure lb, qui peut être obtenue par une machine automatique. Bien évidemment, le tube B sera convenablement orienté de façon que La branche longitudinale 2a de la rainure soit dans l'alignement de L'ergot 1. Cependant, on doit en outre signaler que le tube B doit posséder, par rapport à la machine, une certaine
Liberté de rotation autour de son axe. Ceci peut être obtenu de diverses manières, en particulier si Le tube B comporte un épaulement, non représenté, à une certaine distance de sa face terminale 3, la poussée de la machine sur l'épaulement s'effectuant par
L'intermédiaire d'un organe tournant librement.The automatic coupling and locking of tubes A and B is carried out as follows. Assuming that the tube A is fixed, the tube B is brought towards it by a translation, along the arrow F in FIG. 1b, which can be obtained by an automatic machine. Obviously, the tube B will be suitably oriented so that the longitudinal branch 2a of the groove is in alignment with the lug 1. However, it should also be noted that the tube B must have, relative to the machine, a certain
Freedom of rotation around its axis. This can be obtained in various ways, in particular if the tube B has a shoulder, not shown, at a certain distance from its end face 3, the thrust of the machine on the shoulder being effected by
The intermediary of a freely rotating organ.
Le tube B étant engagé sur le tube A, L'ergot 1 se déplace tout d'abord dans la branche longitudinale 2a (figure 2). The tube B being engaged on the tube A, the lug 1 first moves in the longitudinal branch 2a (Figure 2).
Le mouvement de translation se poursuivant, L'ergot 1 vient en contact avec la portion coudée 4b qui constitue une rampe d'appui transversal de la butée 4 et repousse cette dernière contre
L'action du ressort 5 (figure 3).The translational movement continuing, the lug 1 comes into contact with the bent portion 4b which constitutes a transverse support ramp of the stop 4 and pushes the latter against
The action of spring 5 (Figure 3).
Lorsque L'ergot 1 atteint L'extrémité de la branche 2a, il est en appui sur la première portion 4a de la butée 4 qui se trouve alors escamotée transversalement dans le logement 2d (figure 4). A ce moment, L'entrée de la branche transversale 2b de la rainure se trouve dégagée et ouverte devant L'ergot 1. Le ressort 5, prenant appui sur ce dernier, par l'intermédiaire de la première portion 4a de la butée, fait pivoter le tube B autour de son axe, de sorte que L'ergot 1 se trouve emprisonné axialement dans la branche transversale 2b. When the lug 1 reaches the end of the branch 2a, it is supported on the first portion 4a of the stop 4 which is then retracted transversely in the housing 2d (Figure 4). At this time, the entry of the transverse branch 2b of the groove is clear and open in front of the lug 1. The spring 5, bearing on the latter, by means of the first portion 4a of the stop, pivot the tube B around its axis, so that the lug 1 is trapped axially in the transverse branch 2b.
Le verrouillage de l'accouplement des deux tubes coaxiaux est alors terminé et la butée 4 reprend sa position de repos dans la branche longitudinale 2a de la rainure (figure 5). The locking of the coupling of the two coaxial tubes is then completed and the stop 4 returns to its rest position in the longitudinal branch 2a of the groove (FIG. 5).
S'il est avantageux de prévoir un verrouillage automatique au cours du mouvement de translation nécessaire à l'accouple- ment de deux tubes, en revanche leur démontage se fera en général manuellement. IL suffit à cet effet de faire pivoter le tube B par rapport au tube A, contre L'action du ressort 5, ce qui amène
L'ergot 1 dans la branche longitudinale 2a de la rainure et permet alors le coulissement des deux tubes.If it is advantageous to provide an automatic locking during the translational movement necessary for the coupling of two tubes, on the other hand their disassembly will generally be done manually. It suffices for this purpose to rotate the tube B relative to the tube A, against the action of the spring 5, which brings
The lug 1 in the longitudinal branch 2a of the groove and then allows the sliding of the two tubes.
Si l'on se reporte maintenant à la figure 6, on voit une variante avantageuse de réalisation. Les éléments correspondant à ceux qui ont déjà été décrits portent Les mêmes références augmentées de 10. On soulignera cependant que la butée 14, avec ses deux portions 14a et 14b, est liée à une lame flexible 15, constituant avantageusement la queue de la butée et encastrée dans
La paroi du tube B. De préférence, et comme représenté au dessin, la lame flexible 15 est, dans la position de repos de la butée 14, située sensiblement dans un plan diamétral longitudinal du tube.If we now refer to Figure 6, we see an advantageous alternative embodiment. The elements corresponding to those which have already been described bear the same references increased by 10. It will however be emphasized that the stop 14, with its two portions 14a and 14b, is linked to a flexible blade 15, advantageously constituting the tail of the stop and embedded in
The wall of the tube B. Preferably, and as shown in the drawing, the flexible blade 15 is, in the rest position of the stop 14, located substantially in a longitudinal diametral plane of the tube.
Bien évidemment, il est prévu des moyens pour Limiter l'emmanche- ment des deux tubes l'un dans L'autre, ces moyens pouvant être constitués par une butée axiale telle que celle représentée en 12e sur la figure 6.Obviously, means are provided to limit the fitting of the two tubes into one another, these means being able to be constituted by an axial stop such as that shown in 12e in FIG. 6.
On signalera enfin qu'il peut être avantageux de disposer de moyens simples pour vérifier visuellement le verrouillage du dispositif d'accouplement. A cet effet, la face terminale 3 du tube extérieur B présente une échancrure 6 dont la section, par exemple semi-cylindrique, correspond à un repère circulaire en creux 7 sur la face externe du tube intérieur A. La distance angulaire entre L'axe de L'ergot 1 et le centre du repère 7 est égale à la distance angulaire entre L'axe de l'échancrure 6 et le milieu de la branche transversale 2b de la rainure. Finally, it should be noted that it may be advantageous to have simple means for visually checking the locking of the coupling device. To this end, the end face 3 of the outer tube B has a notch 6 whose section, for example semi-cylindrical, corresponds to a hollow circular mark 7 on the outer face of the inner tube A. The angular distance between the axis of the lug 1 and the center of the mark 7 is equal to the angular distance between the axis of the notch 6 and the middle of the transverse branch 2b of the groove.
Après verrouillage dans Les conditions qui ont été décrites, la base de l'échancrure 6 sur la face interne du tube A vient visuellement coïncider avec le repère 7, permettant la vérification aisée du montage. After locking under the conditions which have been described, the base of the notch 6 on the internal face of the tube A visually coincides with the mark 7, allowing easy verification of the mounting.
