Description

La présente invention se rapporte à un système de maintien, en particulier pour un élément telle qu'une bride de serrage d'une pièce.The present invention relates to a holding system, in particular for an element such as a clamp for a workpiece.

Le positionnement angulaire de ce type d'élément est difficile car s'il est vissé sur un support, suivant le serrage effectué, sa position angulaire pourrait varier. Ceci est particulièrement critique pour une bride de serrage qui doit être positionnée précisément angulairement afin de pouvoir serrer correctement la pièce.The angular positioning of this type of element is difficult because if it is screwed onto a support, depending on the tightening done, its angular position could vary. This is particularly critical for a clamp which must be positioned precisely angularly in order to properly clamp the workpiece.

Il est aussi possible de fixer la bride en premier sur le support pour ensuite visser l'autre partie par dessous. Cependant, dans ce cas, Il est nécessaire d'accéder au support par le dessous. Un tel exemple est montré dans la demande de brevet FR 2863190 A1 . Un autre exemple est montré dans le document US 8,678,362 B1 . Le même problème de positionnement peut se présenter également pour d'autres éléments de montage tels que des butées de positionnement ou des éléments de support.It is also possible to fix the flange first on the support then screw the other part from below. However, in this case, it is necessary to access the support from below. Such an example is shown in the patent application FR 2863190 A1 . Another example is shown in the document US 8,678,362 B1 . The same positioning problem may also occur for other mounting elements such as positioning stops or support members.

L'objet de la présente invention est de proposer un système de maintien qui permette à la fois un positionnement angulaire précis et un positionnement angulaire à 360°. Le dispositif présente également un encombrement réduit.The object of the present invention is to provide a holding system that allows both precise angular positioning and 360 ° angular positioning. The device also has a small footprint.

Le système de maintien selon l'invention comprend un élément de montage d'axe X, un support qui présente une ouverture d'axe X dans laquelle est placé l'élément de montage, il est caractérisé en ce que l'élément de montage comprend une coulisse dans laquelle est disposé un coin de verrouillage qui coopére avec au moins un renvoi d'angle, le support comprend une empreinte intérieure disposée dans l'ouverture et le coin de verrouillage coopère avec l'empreinte intérieure. L'élément de montage de maintien est ainsi facilement positionnable angulairement. Il y a de préférence deux renvois d'angle disposés de façon sensiblement diamétralement opposée. La commande par le renvoi d'angle permet d'effectuer la fixation en ayant accès à un seul côté de l'ouverture.The holding system according to the invention comprises an X-axis mounting member, a support having an X-axis opening in which the mounting member is located, characterized in that the mounting member comprises a slider in which is disposed a locking wedge which cooperates with at least one bevel gear, the carrier comprises an inner recess disposed in the opening and the locking wedge cooperates with the inner recess. The holding mounting element is thus easily angularly positionable. There are preferably two angle gears arranged substantially diametrically opposite. The control by the angle gear makes it possible to carry out the fixing by having access to only one side of the opening.

Dans une forme de réalisation particulière, le système comporte un vérin placé dans l'ouverture. Le vérin peut être hydraulique ou pneumatique ou un actionneur mécanique ou électromécanique.In a particular embodiment, the system comprises a jack placed in the opening. The jack can be hydraulic or pneumatic or a mechanical or electromechanical actuator.

Avantageusement, l'élément de montage (2) et le vérin (3) peuvent être soit montés en pivotement autour de l'axe X, soit bloqués en pivotement. Ainsi, le positionnement précis de l'élément de montage peut être assuré soit par le réglage en pivotement, soit par le montage en position bloquée.Advantageously, the mounting member (2) and the jack (3) may be either pivotally mounted about the X axis or pivotally locked. Thus, the precise positioning of the mounting element can be ensured either by the adjustment in pivoting or by mounting in the locked position.

Selon un mode de réalisation, l'ouverture est un trou aveugle. Le dispositif peut être utilisé indifféremment quand le trou est traversant ou quand il est aveugle.According to one embodiment, the opening is a blind hole. The device can be used indifferently when the hole is through or when it is blind.

Avantageusement, le renvoi d'angle fait un angle compris entre 5 et 45°, de préférence entre 15 et 30° par rapport à l'axe X. Ainsi, si le coin de verrouillage a un déplacement perpendiculaire à l'axe X de l'élément de montage, le renvoi permet ainsi de bloquer le coin de verrouillage par un mouvement du renvoi parallèle à l'axe X. La force de ce mouvement est amplifiée grâce au choix de l'angle, tout en étant réversible.Advantageously, the angle gear makes an angle of between 5 and 45 °, preferably between 15 and 30 ° relative to the X axis. Thus, if the locking wedge has a displacement perpendicular to the X axis of the X mounting element, the return thus allows to block the locking wedge by a movement of the return parallel to the axis X. The force of this movement is amplified through the choice of the angle, while being reversible.

Avantageusement, l'élément de montage comprend une face de butée coopérant avec une face inférieure de l'empreinte intérieure. La face de butée est placée de préférence du coté de l'insertion de l'élément de montage dans le support, ainsi lorsque l'on positionne l'élément de montage sur le support, celui-ci est bloqué selon l'axe X. De préférence cette face de butée coopère avec un appui disposé sur le support. Selon une caractéristique avantageuse, le coin comporte un cône de plaquage supérieur incliné apte à venir en appui contre une face supérieure inclinée de l'empreinte intérieure de manière à plaquer l'élément de montage sur la face de butée. Ainsi la position de l'élément de montage dans le trou est déterminée par l'appui contre la face de butée. Les appuis contre les surfaces coniques permet en outre d'augmenter les forces de contact, et donc la puissance du maintien.Advantageously, the mounting element comprises an abutment face cooperating with a lower face of the internal cavity. The abutment face is preferably placed on the side of the insertion of the mounting element into the support, so when the mounting element is positioned on the support, the latter is locked along the X axis. Preferably this abutment face cooperates with a support disposed on the support. According to an advantageous characteristic, the wedge comprises an inclined top plating cone adapted to bear against an inclined upper surface of the inner recess so as to press the mounting element on the abutment face. Thus the position of the mounting element in the hole is determined by the bearing against the abutment face. The support against the conical surfaces also makes it possible to increase the contact forces, and therefore the power of the support.

La face de butée est avantageusement un cône de plaquage.Selon une disposition complémentaire, le dispositif comporte un élément élastique logé dans une gorge circulaire et en appui sur le coin de verrouillage, l'élément élastique tendant à maintenir le coin de verrouillage contre le renvoi d'angle. Ainsi le démontage du dispositif est aisé, le retrait du renvoi d'angle permettant d'obtenir le dégagement du coin de verrouillage hors de la rainure. L'élément élastique est par exemple un jonc. La section du jonc peut être circulaire, mais elle pourrait aussi être polygonale, par exemple carrée ou rectangulaire.The abutment face is advantageously a plating cone.According to a complementary arrangement, the device comprises an elastic element housed in a circular groove and resting on the locking wedge, the elastic element tending to hold the locking wedge against the return angle. Thus the disassembly of the device is easy, the removal of the angle gear for obtaining clearance of the locking wedge out of the groove. The elastic element is for example a rod. The section of the ring may be circular, but it could also be polygonal, for example square or rectangular.

Avantageusement, l'élément de montage est une bride de serrage.Advantageously, the mounting element is a clamping flange.

Avantageusement, l'ouverture est circulaire.Advantageously, the opening is circular.

Avantageusement, l'empreinte intérieure est une rainure intérieure circulaire.Advantageously, the inner imprint is a circular inner groove.

Alternativement, l'empreinte intérieure est formée par une pluralité d'encoches. Chacune des encoches est apte à recevoir l'un des coins de verrouillage. Cette coopération assure une indexation angulaire de l'élément de montage dans l'ouverture.Alternatively, the indentation is formed by a plurality of notches. Each of the notches is adapted to receive one of the locking wedges. This cooperation provides angular indexing of the mounting element in the opening.

L'invention concerne également un procédé de maintien d'un élément de montage dans un support présentant une ouverture dans lequel est placé l'élément de montage comprenant une coulisse, dans laquelle est disposé un coin de verrouillage coopérant avec un renvoi d'angle, le procédé est caractérisé en ce qu'il consiste à positionner l'élément de montage dans l'ouverture , à disposer le coin de verrouillage en vis-à-vis d'une empreinte intérieure disposée dans l'ouverture, à pousser le renvoi d'angle entre le coin de verrouillage et la coulisse jusqu'à que le coin de verrouillage entre en contact avec l'empreinte intérieure.The invention also relates to a method for holding a mounting member in a support having an opening in which is placed the mounting member comprising a slide, in which is disposed a locking wedge cooperating with a bevel gear, the method is characterized in that it consists in positioning the mounting element in the opening, arranging the locking wedge opposite an internal cavity disposed in the opening, pushing the return of angle between the locking wedge and the slider until the locking wedge comes into contact with the indentation.

Selon une disposition particulière, il comprend une étape consistant à mettre en butée une face de butée, disposée sur l'élément de montage, sur une face inférieure de l'empreinte intérieure. Ainsi l'élément de montage est bloqué suivant son axe X.In a particular arrangement, it comprises a step of abutting an abutment face disposed on the mounting member on a lower face of the indentation. Thus the mounting element is blocked along its axis X.

On considérera dans la suite de la description que le haut correspond au haut des figures.It will be considered in the remainder of the description that the top corresponds to the top of the figures.

Le dispositif de maintien comprend un support 1 dans lequel sont placés un élément de montage 2 tel qu'une bride de serrage et un vérin 3. Le vérin 3 est destiné à donner un mouvement selon un axe X à la bride 2. L'axe X est disposé verticalement sur les figures et pour la description qui va suivre.The holding device comprises a support 1 in which are placed a mounting element 2 such as a clamping flange and a jack 3. The jack 3 is intended to give a movement along an axis X to the flange 2. The axis X is arranged vertically in the figures and for the description which follows.

L'élément de montage 2 présente une coulisse 21 d'axe radial, c'est-à-dire perpendiculaire à l'axe X. Un coin de verrouillage 4 est placé dans la coulisse 21. Le coin 4 est entouré d'un jonc 6 élastique qui permet son rappel en position rentré dans la coulisse 21 et qui se loge dans une gorge circulaire de la bride, laquelle s'étend également sur le coin de verrouillage 4. La coulisse 21 communique avec au moins une cheminée 22 (ici deux diamétralement opposées) d'axe X' parallèle à l'axe X dans laquelle est placée un renvoi d'angle 5.The mounting element 2 has a slide 21 of radial axis, that is to say perpendicular to the X axis. A locking wedge 4 is placed in the slide 21. The wedge 4 is surrounded by a rod 6 elastic which allows its return in the retracted position in the slide 21 and which is housed in a circular groove of the flange, which also extends on the locking wedge 4. The slide 21 communicates with at least one chimney 22 (here two diametrically opposed) of axis X 'parallel to the axis X in which is placed an angle gear 5.

Le coin de verrouillage 4 présente une face biseautée 40 placée du coté intérieure de la coulisse 21. Cette face biseautée 40 coopère avec une face biseautée 50 du renvoi 5. Les faces biseautées 40 et 50 ont de préférence un angle de 15 à 30° par rapport à l'axe X.The locking wedge 4 has a bevelled face 40 placed on the inner side of the slide 21. This bevelled face 40 cooperates with a beveled face 50 of the reference gear 5. The bevelled faces 40 and 50 preferably have an angle of 15 to 30 ° relative to the X axis.

Le support 1 présente une ouverture 11 circulaire d'axe X qui a une rainure intérieure circulaire 10 destinée à recevoir le coin 4. Cette rainure intérieure 10 a un profil avec deux faces inclinées circulaires: une face supérieure 13 et une face inférieure 12. Le coin 4 a un cône de plaquage supérieur 41 incliné apte à venir en appui contre la face supérieure 13 de la rainure intérieure 10. L'élément de montage 2 a un cône de plaquage 20 destiné à venir en appui sur la face inférieure 12 de la rainure intérieure 10.The support 1 has an aperture 11 circular X axis which has a circular inner groove 10 for receiving the corner 4. This inner groove 10 has a profile with two circular inclined faces: an upper face 13 and a lower face 12. The corner 4 has a tapered upper inclined cone 41 adapted to bear against the upper face 13 of the inner groove 10. The mounting member 2 has a plating cone 20 intended to bear on the lower face 12 of the inner groove 10.

Nous allons maintenant décrire le procédé qui permet le maintien de l'élément de montage 2 dans le support 1. L'élément de montage 2 est placé sur le piston 3 dans l'ouverture 11 circulaire du support 1 par un mouvement vertical selon l'axe X jusqu'à ce que le cône de plaquage 20 vienne en contact avec la face inférieur 12 de la rainure intérieure 10. On positionne angulairement l'élément de montage 2 sur le support 1, une fois la position angulaire souhaitée obtenue on exerce un mouvement selon l'axe X' vers le bas aux renvois d'angle 5 afin de pousser le coin de verrouillage 4 vers le fond de la rainure intérieure 10 jusqu'à qu'il arrive en butée. Ce mouvement est ici réalisé par vissage d'une vis 7 sur la cheminée 22 de l'élément de montage 2, la vis 7 en descendant pousse le renvoi 5 vers le bas et par sa face biseautée 50, il va pousser le coin 4.We will now describe the method that allows the maintenance of the mounting member 2 in the support 1. The mounting member 2 is placed on the piston 3 in the opening 11 of the circular support 1 by a vertical movement according to the X axis until the plating cone 20 comes into contact with the lower face 12 of the inner groove 10. The mounting element 2 is angularly positioned on the support 1, once the desired angular position is obtained a movement along the X 'axis downwards to the corner jacks 5 to push the locking wedge 4 towards the bottom of the inner groove 10 until it comes to a stop. This movement is here made by screwing a screw 7 on the chimney 22 of the mounting element 2, the screw 7 downwards pushes the return 5 downwards and its bevelled face 50, it will push the corner 4.

Pour déverrouiller l'élément de montage 2, on effectue la démarche inverse, mais après la remontée du renvoi 5, le cône de verrouillage 4 est repoussé vers le fond de la coulisse 21 par le jonc 6.To unlock the mounting element 2, the opposite step is made, but after raising the return 5, the locking cone 4 is pushed towards the bottom of the slide 21 by the rod 6.

Les figures 6 et 7 montrent un deuxième mode de réalisation où l'ouverture 11 présente une partie circulaire 110 placé en bas du support et une partie carrée 111 en haut. Dans ce cas, l'élément de montage 2 a une partie haute 23 de profil carré et une partie basse 24 de profil circulaire. La partie haute 23 a un cône de verrouillage 4 à chaque angle de la partie haute 23 carrée.The Figures 6 and 7 show a second embodiment where the opening 11 has a circular portion 110 placed at the bottom of the support and a square portion 111 at the top. In this case, the mounting element 2 has an upper part 23 of square profile and a lower part 24 of circular profile. The upper part 23 has a locking cone 4 at each corner of the upper part 23 square.

Sur les figures 8 et 9, montrant un troisième mode de réalisation de l'invention, l'ouverture 11 a une partie circulaire 110 en bas et une partie rectangulaire 112 en haut. L'élément de montage 2 a une partie haute 25 avec un profil rectangulaire. Les cônes de verrouillages 4 sont répartis sur chaque coté du rectangle, donc soit au milieu d'un coté s'il n'y en a qu'un cône de verrouillage 4, soit s'ils sont au nombre de deux équidistants.On the Figures 8 and 9 , showing a third embodiment of the invention, the opening 11 has a circular portion 110 at the bottom and a rectangular portion 112 at the top. The mounting member 2 has an upper portion 25 with a rectangular profile. The locking cones 4 are distributed on each side of the rectangle, so either in the middle of one side if there is only one locking cone 4, or if there are two equidistant.

Dans un quatrième mode de réalisation, tel que représenté sur les figures 10 et 11, la rainure intérieure est remplacée par des encoches 10' dans lesquelles les coins de verrouillage 4, de forme adaptée correspondante, viennent se loger. Ainsi, l'orientation de l'élément de montage 2 est prédéterminée par la position des encoches 10'.In a fourth embodiment, as shown in the Figures 10 and 11 , the inner groove is replaced by notches 10 'in which the locking wedges 4, correspondingly adapted form, are housed. Thus, the orientation of the mounting member 2 is predetermined by the position of the notches 10 '.

L'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits à titre d'exemple. Ainsi les faces biseautées 40 et 50 pourront faire un angle différent, mais il faut que la somme de leur angle respectif soit égale à l'angle entre les axes de coulissement, la valeur de l'angle permettant un déplacement plus ou moins important du coin de verrouillage 4. Le cône de plaquage peut être remplacé par un épaulement simple.The invention is not limited to the embodiments which have just been described by way of example. Thus the bevelled faces 40 and 50 may have a different angle, but the sum of their respective angle must be equal to the angle between the sliding axes, the value of the angle allowing more or less significant displacement of the corner 4. The ply cone can be replaced by a single shoulder.
