Description

Ensemble de motorisation électrique modulaire pour pince à souderModular electric motor assembly for welding pliers
La présente invention concerne un ensemble de motorisation électrique pour pince à souder avec un moteur électrique de pince à souder, du type comprenant une carcasse munie d'une bride de fixation frontale et portant le stator, ladite carcasse étant fermée à ses extrémités par un flasque frontal et un flasque arrière, un rotor tournant dans le stator et muni d'un arbre moteur, le flasque arrière étant agencé pour porter la connectique d'alimentation du moteur et éventuellement des moyens de commande du moteur tels que résolveurs, codeurs et/ou encodeurs, le flasque frontal supportant l'arbre moteur.The present invention relates to an electric motor assembly for welding tongs with an electric welding tong motor, of the type comprising a carcass provided with a front fixing flange and carrying the stator, said carcass being closed at its ends by a flange front and a rear flange, a rotor rotating in the stator and provided with a motor shaft, the rear flange being arranged to carry the power supply connection of the motor and possibly of the motor control means such as resolvers, encoders and / or encoders, the front flange supporting the motor shaft.
De tels ensembles de moteurs électriques sont utilisés pour la commande d'ouverture/fermeture de pinces à souder et remplacent avantageusement les commandes pneumatiques ou hydrauliques précédemment employées.Such sets of electric motors are used for the opening / closing control of welding tongs and advantageously replace the pneumatic or hydraulic controls previously used.
Un inconvénient majeur des ensembles de moteur électrique connus jusqu'à présent pour une telle exploitation réside dans le fait qu'ils doivent, pour une même puissance du moteur, être en pratique dessinés spécialement pour chaque utilisation, en particulier pour tenir compte du type de refroidissement nécessité par l'utilisation prévue, de la connectique et des commandes spécifiques à cette utilisation, par le type de transmission mécanique choisi, etc.A major drawback of the electric motor assemblies known hitherto for such an operation lies in the fact that, for the same power of the motor, they must in practice be specially designed for each use, in particular to take account of the type of cooling required by the intended use, the connectors and controls specific to this use, by the type of mechanical transmission chosen, etc.
Il en résulte une complication élevée de la fabrication et du stockage, qui entraîne un coût important et un grand délai de fabrication.This results in a high complication of manufacturing and storage, which involves a high cost and a long manufacturing time.
La présente invention vise à pallier ces inconvénients des ensembles de moteur électrique connus en permettant une réduction importante du coût et du délai de fabrication grâce à une conception modulaire de l'ensemble.The present invention aims to overcome these drawbacks of known electric motor assemblies by allowing a significant reduction in cost and manufacturing time thanks to a modular design of the assembly.
A cet effet, l'ensemble de moteur électrique selon l'invention est caractérisé par le fait que la carcasse est agencée pour recevoir optionnellement un module de refroidissement interchangeable. Avec l'ensemble selon l'invention, l'équipement optionnel de refroidissement peut être mis en place par le fabricant de la pince à souder, avant montage de la motorisation sur la pince assemblée.To this end, the electric motor assembly according to the invention is characterized in that the carcass is arranged to optionally receive an interchangeable cooling module. With the assembly according to the invention, the optional cooling equipment can be installed by the manufacturer of the welding gun, before mounting the motorization on the assembled gun.
Sans module de refroidissement ajouté, le moteur électrique est refroidi par convection naturelle stricte.With no added cooling module, the electric motor is cooled by strict natural convection.
Les modules de refroidissement peuvent avantageusement comprendre une chemise nervurée ou ailetée de convection naturelle, une chemise creuse de passage d'air forcé par un ventilateur ou une chemise de circulation d'un liquide de refroidissement.The cooling modules can advantageously comprise a ribbed jacket or fin with natural convection, a hollow jacket for the passage of air forced by a fan or a jacket for circulation of a cooling liquid.
La conception modulaire de l'ensemble de motorisation électrique selon l'invention permet, à partir d'une carcasse standard, d'adapter des composants d'alimentation et de commande ou des transmissions mécaniques spécifiques à l'utilisation prévue.The modular design of the electric motor assembly according to the invention makes it possible, from a standard carcass, to adapt supply and control components or mechanical transmissions specific to the intended use.
A cet effet, selon une forme de réalisation préférée de l'invention, le flasque arrière pré-équipé est agencé pour être fixé de manière interchangeable sur la carcasse. De même, l'invention prévoit que le flasque frontal est agencé pour être fixé de manière interchangeable sur la bride de fixation frontale de la carcasse ; le rotor étant interchangeable pour être adapté au type de transmission déterminé par le flasque frontal.To this end, according to a preferred embodiment of the invention, the pre-equipped rear flange is arranged to be fixed interchangeably on the carcass. Similarly, the invention provides that the front flange is arranged to be fixed interchangeably on the front fixing flange of the carcass; the rotor being interchangeable to be adapted to the type of transmission determined by the front flange.
Selon un développement de l'invention, l'ensemble de motorisation électrique comprend un module de freinage agencé pour être monté optionnellement entre le flasque arrière et la carcasse.According to a development of the invention, the electric motor assembly comprises a braking module arranged to be optionally mounted between the rear flange and the carcass.
L'ensemble selon l'invention permet en conséquence d'équiper au choix une carcasse moteur standard munie d'un stator avec des modules choisis en fonction de l'utilisation prévue et permettant d'obtenir une capabilité optimale en fonction de l'utilisation prévue.The assembly according to the invention therefore makes it possible to equip, as desired, a standard motor carcass provided with a stator with modules chosen according to the intended use and making it possible to obtain optimum capability according to the intended use. .
Le fabricant de pinces à souder dispose alors en stock de carcasses moteurs standards et de composants modulaires et peut ainsi assembler des ensembles de motorisation électrique adaptés aux utilisations prévues, avant de les monter sur les pinces à souder qu'il aura assemblées. Le prix de revient et les délais sont nettement réduits par rapport à un ensemble de motorisation spécifique commandé au fabricant de moteurs.The manufacturer of welding tongs then has in stock standard motor casings and modular components and can thus assemble sets of electric motors adapted to the intended uses, before mounting them on the welding tongs that he will have assembled. The cost price and lead times are significantly reduced compared to a specific engine package ordered from the engine manufacturer.
L'invention sera bien comprise à la lecture de la description suivante en référence au dessin annexé dans lequel :The invention will be clearly understood on reading the following description with reference to the accompanying drawing in which:

L'ensemble de motorisation électrique modulaire selon l'invention, représenté schématiquement à la figure 1 , comprend une carcasse 1 munie d'une bride de fixation frontale 2 et contenant le stator (non représenté) du moteur électrique. Un rotor 3 est muni d'un arbre moteur 4 qui est porté par un flasque frontal 5, un flasque arrière 6 fermant la carcasse 1 à l'opposé de la bride de fixation 2.The modular electric motor assembly according to the invention, shown diagrammatically in FIG. 1, comprises a carcass 1 provided with a front fixing flange 2 and containing the stator (not shown) of the electric motor. A rotor 3 is provided with a drive shaft 4 which is carried by a front flange 5, a rear flange 6 closing the carcass 1 opposite the fixing flange 2.
L'ensemble peut en outre comprendre un système de refroidissement 7 entourant la carcasse 1 et un module de freinage 8.The assembly can also include a cooling system 7 surrounding the carcass 1 and a braking module 8.
Jusqu'à présent, un tel ensemble est conçu en fonction d 'une application précise et assemblé par le fabricant de moteur ou tout autre fabricant. Il en résulte un coût élevé, du fait des petites séries commandées, et un long délai de fabrication.So far, such an assembly is designed for a specific application and assembled by the engine manufacturer or any other manufacturer. This results in a high cost, due to the small series ordered, and a long manufacturing time.
La présente invention prévoit, sur un sous-ensemble standard, comprenant une carcasse 1 avec sa bride de fixation et son stator, d'assembler les autres composants choisis dans un stock de modules en fonction de l'application particulière prévue.The present invention provides, on a standard sub-assembly, comprising a carcass 1 with its fixing flange and its stator, to assemble the other components chosen from a stock of modules according to the particular application envisaged.
Le rotor 3 peut par exemple porter un arbre 4 cannelé pour une prise directe sur des pignons de renvoi ou un arbre 4 creux muni d'un écrou à rouleaux satellites ou à billes assurant un déplacement linéaire d'une vis sans fin (non représentée). Le flasque frontal 5 choisi sera alors un flasque à simple palier pour l'arbre cannelé ou un flasque à palier combiné permettant l'intégration de la vis sans fin et la reprise des efforts axiaux.The rotor 3 can, for example, carry a splined shaft 4 for direct engagement with idler gears or a hollow shaft 4 provided with a nut with satellite or ball rollers ensuring a linear movement of a worm (not shown) . The front flange 5 chosen will then be a single-bearing flange for the splined shaft or a combined bearing flange allowing the integration of the worm and the resumption of axial forces.
Le flasque arrière 6 qui sera monté comportera la connectique spécifique à l'application prévue. Il pourra comprendre des moyens de commande du moteur électrique tels que résolveurs, codeurs et/ou encodeurs, prémontés et précâblés.The rear flange 6 which will be mounted will include the specific connectors for the intended application. It may include means for controlling the electric motor such as resolvers, coders and / or encoders, pre-assembled and pre-wired.
Un module de freinage 8, par exemple à manque de courant, pourra être interposé entre la carcasse 1 et le flasque arrière 6.A braking module 8, for example with a lack of current, may be interposed between the carcass 1 and the rear flange 6.
Selon une caractéristique importante de l'invention, l'ensemble pourra être équipé d'un module de refroidissement 7 entourant la carcasse 1. En l'absence de module de refroidissement (figure 2), le moteur est à refroidissement par convection naturelle stricte.According to an important characteristic of the invention, the assembly may be equipped with a cooling module 7 surrounding the carcass 1. In the absence of a cooling module (Figure 2), the engine is cooled by strict natural convection.
Le module de refroidissement peut être constitué par une chemise 9 nervurée ou munie d'ailettes (figure 3) assurant une convection naturelle renforcée.The cooling module can consist of a ribbed jacket 9 or provided with fins (FIG. 3) ensuring enhanced natural convection.
Pour les applications nécessitant un refroidissement plus fort, le module de refroidissement est constitué par une chemise creuse 10 (figure 4) munie d'un ventilateur arrière 11 et d'une expulsion frontale 12.For applications requiring stronger cooling, the cooling module consists of a hollow jacket 10 (FIG. 4) fitted with a rear fan 11 and a front exhaust 12.
Selon le besoin, le module de refroidissement pourra être constitué par une chemise de circulation 13 d'un liquide de refroidissement (figure 5), ladite chemise étant creuse et/ou munie d'un serpentin. Depending on the need, the cooling module can be constituted by a circulation jacket 13 for a cooling liquid (FIG. 5), said jacket being hollow and / or provided with a coil.
