Description

La présente invention concerne le domaine du serrage de pièces par bridage, en particulier de pièces de tôles à assembler par soudage, et a pour objet un dispositif de serrage pneumatique à genouillère.The present invention relates to the field of clamping parts by clamping, in particular sheet metal parts to be assembled by welding, and relates to a pneumatic toggle clamping device.

Actuellement, les dispositifs existant de ce type désignés généralement par le terme générique "serrages" sont essentiellement constitués par un vérin hydraulique ou pneumatique agissant par l'intermédiaire d'une chape sur un embiellage solidaire par un axe d'un bras de bridage, la chape étant guidée dans un corps solidaire du corps du vérin et renfermant l'embiellage.Currently, existing devices of this type generally designated by the generic term "clamps" are essentially constituted by a hydraulic or pneumatic cylinder acting by means of a yoke on a connecting rod attached to one axis of a clamping arm, the yoke being guided in a body integral with the cylinder body and containing the connecting rod assembly.

Dans ces dispositifs connus, le blocage du bras de bridage en position de service est rendu irréversible par dépassement de la position d'alignement des axes de l'embiellage à la manière d'une genouillère.In these known devices, the locking of the clamping arm in the service position is made irreversible by exceeding the position of alignment of the axes of the crankshaft in the manner of a toggle.

Cependant, dans ces dispositifs, le troisième axe est généralement remplacé par la surface de contact, soit de la chape avec le corps, soit d'un ou de plusieurs galets de guidage solidaire de la chape avec le corps, de sorte que le passage de la position d'alignement nécessite la mise en oeuvre d'efforts extrêmement importants tendant à déformer la surface de guidage de la chape ainsi qu'à provoquer une usure rapide des différents paliers de l'embiellage, de sorte que la précision du serrage, en cas d'une variation d'épaisseur des tôles à serrer, et le maintien d'une force de serrage constante sont pratiquement impossibles à assurer à long terme. En outre, dans ces dispositions ou serrages connus le desserrage du bras de bridage est souvent difficile du fait des forces de blocage à surmonter, nécessitant un surdimen- sionnement du vérin d'actionnement entraînant une augmentation correspondante du prix de revient.However, in these devices, the third axis is generally replaced by the contact surface, either of the yoke with the body, or of one or more guide rollers integral with the yoke with the body, so that the passage of the alignment position requires the implementation of extremely significant efforts tending to deform the guide surface of the yoke as well as cause rapid wear of the different bearings of the crankshaft, so that the precision of the tightening, in the event of a variation in thickness of the sheets to be tightened, and the maintenance of '' A constant clamping force is practically impossible to ensure in the long term. In addition, in these known arrangements or tightenings, the loosening of the clamping arm is often difficult because of the blocking forces to be overcome, requiring an oversizing of the actuating cylinder resulting in a corresponding increase in the cost price.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un dispositif de serrage pneumatique à genouillère, essentiellement constitué par un corps de bridage en deux demi-coquilles assemblées entre elles dans lequel est montée à coulissement une chape actionnant un bras de bridage par l'intermédiaire d'un levier, et par un vérin qui est relié au corps de bridage, et dont la tige est solidaire de la chape, qui est guidée dans le corps de bridage, contre une face d'appui de ce dernier au moyen d'un élément intermédiaire de guidage, caractérisé en ce que l'élément intermédiaire de guidage est élastiquement déformable pendant le serrage, en particulier lors du dépassement de la position d'alignement.It has, in effect, a pneumatic toggle clamping device, essentially constituted by a clamping body in two half-shells assembled together in which is slidably mounted a yoke actuating a clamping arm by means of a lever, and by a jack which is connected to the clamping body, and whose rod is integral with the yoke, which is guided in the clamping body, against a bearing face of the latter by means of an intermediate element guide, characterized in that the intermediate guide element is elastically deformable during tightening, in particular when the alignment position is exceeded.

Conformément à une caractéristique de l'invention, l'élément intermédiaire de guidage est constitué par deux rails fixés chacun sur la face d'appui d'une demi-coquille du corps de bridage avec interposition d'une pièce élastiquement déformable ou de ressorts de compression.According to a characteristic of the invention, the intermediate guide element consists of two rails each fixed on the bearing face of a half-shell of the clamping body with the interposition of an elastically deformable part or springs of compression.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en coupe et en élévation latérale d'un dispositif conforme à l'invention, et
  • la figure 2 est une vue en élévation frontale et en demi- coupe du dispositif suivant la figure 1.
The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • FIG. 1 is a sectional view in side elevation of a device according to the invention, and
  • FIG. 2 is a front elevation view and in half-section of the device according to FIG. 1.

Conformément à l'invention, et comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, le dispositif de serrage pneumatique à genouillère, qui est essentiellement constitué par un corps de bridage 1, formé par deux demi-coquilles l' assemblées entre elles, et dans lequel est montée à coulissement une chape 2, qui actionne un bras de bridage 3 au moyen d'un levier 4, et par un vérin 5 solidarisé avec le corps de bridage 1, et dont la tige 6 est reliée à la chape 2, qui est guidée dans le corps de bridage 1 contre une face d'appui 7 de ce dernier au moyen d'un élément intermédiaire de guidage 8, est caractérisé en ce que ledit élément intermédiaire de guidage 8 est élastiquement déformable au cours du serrage, en particulier lors du dépassement de la position d'alignement.According to the invention, and as shown more particularly, by way of example, FIG. 1 of the accompanying drawings, the pneumatic toggle clamping device, which is essentially constituted by a clamping body 1, formed by two half shells the assembled together, and in which is slidably mounted a yoke 2, which actuates a clamping arm 3 by means of a lever 4, and by a jack 5 secured to the clamping body 1, and whose rod 6 is connected to the yoke 2, which is guided in the clamping body 1 against a bearing face 7 of the latter by means of an intermediate guide element 8, is characterized in that said intermediate guide element 8 is elastically deformable during tightening, in particular when exceeding the alignment position.

L'élément 8 est avantageusement constitué par deux rails 9 fixés chacun sur la face d'appui 7 d'une demi-coquille l' du corps 1 avec interposition d'une pièce 10 élastiquement déformable (figure 2). Cette pièce 10 est constituée, de préférence, en caoutchouc naturel ou synthétique, ou en toute autre matière ayant des propriétés de déformation élastique. Il est également possible de remplacer la pièce 10 par des ressorts de compression logés, d'une part, dans des alvéoles prévus à cet effet sur la face d'appui 7 des demi-coquilles 1' ou sur la face inférieure des rails 9 et s'appuyant, d'autre part, par leur autre extrémité sur la face inférieure des rails 9 ou sur la face d'appui 7.The element 8 is advantageously constituted by two rails 9 each fixed on the bearing face 7 of a half-shell 1 'of the body 1 with the interposition of a piece 10 which is elastically deformable (FIG. 2). This part 10 is preferably made of natural or synthetic rubber, or any other material having elastic deformation properties. It is also possible to replace the part 10 by compression springs housed, on the one hand, in cells provided for this purpose on the bearing face 7 of the half-shells 1 'or on the underside of the rails 9 and resting, on the other hand, by their other end on the underside of the rails 9 or on the bearing face 7.

Les rails 9 sont avantageusement des rails à section en U, dans lesquels sont guidées les extrémités de l'axe 11 de liaison entre la chape 2 et le levier 4 d'actionnement du bras de bridage 3, et la pièce 10 est logée, de préférence, dans un évidement longitudinal 12 de la face d'appui 7 de chaque demi-coquille l' (figure 2).The rails 9 are advantageously U-section rails, in which the ends of the connecting pin 11 are guided between the yoke 2 and the lever 4 for actuating the clamping arm 3, and the part 10 is housed, preferably, in a longitudinal recess 12 of the bearing face 7 of each half-shell 1a (FIG. 2).

Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, l'élément 8 peut également être constitué uniquement par des rails réalisés en un matériau élastiquement déformable et à résistance de surface élevée, tel que de l'acier à ressort, ou un matériau composite, par exemple à base de fibres de carbone, ces rails reposant alors uniquement par leurs deux extrémités sur des plots de la face d'appui 7 de chaque demi-coquilles 1'.According to an alternative embodiment of the invention, not shown in the appended drawings, the element 8 can also consist solely of rails made of an elastically deformable material and with high surface resistance, such as spring steel, or a composite material, for example based on carbon fibers, these rails then resting only by their two ends on pads of the bearing face 7 of each half-shells 1 '.

Conformément à un autre mode de réalisation de l'invention, l'élément 8 est constitué sous forme d'empilements de lames de ressort s'appuyant à ses extrémités sur des plots de la face d'appui 7 de chaque demi-coquille 1', et sur lesquels glissent ou roulent les extrémités correspondantes de l'axe 11.In accordance with another embodiment of the invention, the element 8 is formed in the form of stacks of spring blades bearing at its ends on pads of the bearing face 7 of each half-shell 1 ' , and on which the corresponding ends of the axis 11 slide or roll.

Enfin, il est également possible de réaliser l'élément 8 sous forme de rails encastrés à leur extrémité tournée vers le vérin 5, ou montés à pivotement à cette extrémité, et s'appuyant à leur autre extrémité sur un élément élastiquement déformable ou sur un ressort de compression solidaire de la face d'appui 7 de chaque demi-coquille 1'.Finally, it is also possible to produce the element 8 in the form of rails embedded at their end facing the jack 5, or pivotally mounted at this end, and bearing at their other end on an elastically deformable element or on a compression spring secured to the bearing face 7 of each half-shell 1 '.

Lors du serrage, au moment où l'axe 11 arrive au point d'alignement, c'est-à-dire lorsque la perpendiculaire du point de contact de la chape 2 avec la face d'appui 7 du corps 1 passe par l'axe 11 et par l'axe 13 de liaison du levier 4 avec le bras de bridage 3, donc lorsqu'il se produit pratiquement un effet d'arc-boutement, il se forme une composante de force qui tend à écraser le rail 9 sur la pièce 10, de sorte que la force obtenue sur le bras 3 peut être notablement amoindrie, et que la courbe de charge dudit bras 3 ne présente plus de pic indésirable.When tightening, when the axis 11 arrives at the alignment point, that is to say when the perpendicular to the point of contact of the yoke 2 with the bearing face 7 of the body 1 passes through the axis 11 and by the axis 13 connecting the lever 4 with the clamping arm 3, so when it practically produces a bracing effect, a force component is formed which tends to crush the rail 9 on the part 10, so that the force obtained on the arm 3 can be significantly reduced, and that the load curve of said arm 3 no longer exhibits an undesirable peak.

Grâce à l'invention, il est possible de réaliser un dispositif de serrage pneumatique à genouillère, dont l'usure des pièces en mouvement est négligeable, qui permet d'obtenir un serrage constant, et qui nécessite des efforts d'ouverture relativement faibles par rapport aux dispositifs existants à capacité de serrage égale.Thanks to the invention, it is possible to carry out a pneumatic toggle clamping device, the wear of the moving parts of which is negligible, which makes it possible to obtain constant clamping, and which requires relatively low opening forces compared to existing devices with equal clamping capacity.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
