Abstract
Description
L'invention concerne un appareil de rodage automatique pour robot de soudage. On sait que les électrodes de soudage doivent subir séquentiellement une opération de rodage qui est précédée d'une opération de fraisage. The invention relates to an automatic lapping apparatus for a welding robot. It is known that the welding electrodes must sequentially undergo a running-in operation which is preceded by a milling operation.
La séquence entre deux opérations de rodage est d'environ 5000 points de soudure.The sequence between two running-in operations is approximately 5000 welding points.
Les électrodes de soudure qui sont le plus souvent disposées coaxialement présentent généralement des extrémités en tronc de cne dont la partie conique doit être taillée et l'extrémité plate rodée. Généralement les électrodes sont remises en état manuellement. L'invention a pour objet un appareil permettant au robot de présenter automatiquement les deux électrodes, de manière alternative au fraisage et au rodage, les outils de fraisage et de rodage étant mis en fonctionnement par le cerveau électronique du robot. The welding electrodes which are most often arranged coaxially generally have cone ends whose conical part must be cut and the flat end ground. Generally the electrodes are repaired manually. The invention relates to an apparatus enabling the robot to automatically present the two electrodes, as an alternative to milling and lapping, the milling and lapping tools being operated by the electronic brain of the robot.
L'appareil selon l'invention est caractérisé en ce qu'il comporte une broche de fraisage et une broche de rodage, des moyens pour entraîner ces broches dans un mouvement de rotation alternative, des moyens pour centrer les deux broches, une fraise double denture conique interne sur deux faces opposées, munie de moyens de fixation 3 la broche de fraisage, un rodoir à deux faces planes opposées abrasives et des moyens de fixation a la broche de rodage. The apparatus according to the invention is characterized in that it comprises a milling spindle and a lapping spindle, means for driving these spindles in an alternating rotational movement, means for centering the two spindles, a double-tooth cutter internal conical on two opposite faces, provided with means 3 for fixing the milling spindle, a lapping machine with two opposite abrasive flat faces and means for fixing to the lapping spindle.
Lors de l'utilisation de cet appareil, le robot le place entre les électrodes et assure l'entratnement des broches. Le fraiseur taille la partie conique de chaque électrode, les copeaux étant formés dans un sens de rotation puis cassés dans l'autre sens. Dans une seconde etape, le rodoir rode l'extrémité plate de chaque électrode. When using this device, the robot places it between the electrodes and drives the pins. The miller cuts the conical part of each electrode, the chips being formed in one direction of rotation and then broken in the other direction. In a second step, the lapping machine rode the flat end of each electrode.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation de 11 appareil selon l'invention, avec référenceauxdessins annexés dans lesquels

Figures 2 and 3 show two views in pers
pective of the bur and lapping, mounted on the

Figure 6 shows a variant.
Tel qu'il est représenté à la Figure 1, l'appareil comporte un bottier 1 monté sur silent-bloc et muni d'un couvercle non représenté, à l'intérieur de ce bottier se trouvent une broche de fraisage 2 et une broche de rodage 3. Chaque broche comporte une collerette 4 définissant de part et d'autre des épaulements 5 et 6 qui servent d'appui à des roulements à aiguilles 7 qui séparent chaque broche du bottier 1 et du couvercle. As shown in Figure 1, the device includes a case 1 mounted on silent block and provided with a cover not shown, inside this case are a milling spindle 2 and a spindle lapping 3. Each spindle has a flange 4 defining on either side the shoulders 5 and 6 which serve as a support for needle bearings 7 which separate each spindle from the case 1 and the cover.
Les collerettes 4 des deux broches comportent chacune sur leur tranche un alésage taraudé 8 permettant de fixer rigidement des manchons 9 et 10 qui servent à la préhension des broches. Chacun de ces manchons 9 et 10 présente une extrémité filetée 11 engagée dans l'un des alésages 8 et à son extrémité opposée, une articulation 12 ou 13 qui le relie à une biellette 14 d'entraI- nement. The flanges 4 of the two pins each have on their edge a threaded bore 8 for rigidly fixing sleeves 9 and 10 which are used for gripping the pins. Each of these sleeves 9 and 10 has a threaded end 11 engaged in one of the bores 8 and at its opposite end, a hinge 12 or 13 which connects it to a link rod 14 for driving.
La biellette 14 comporte en outre une troisième articulation 15 qui la relie à la tige 16 d'un vérin 16a à double effet, lui-méme articulé en 16b sur son support. The link 14 further comprises a third articulation 15 which connects it to the rod 16 of a double-acting cylinder 16a, itself articulated at 16b on its support.
Ce vérin imprime aux broches un mouvement de pivotement alternatif dont le débattement est d'environ 900.This cylinder gives the spindles an alternative pivoting movement, the travel of which is approximately 900.
Pour assurer le centrage des broches, des roulements 17 sont fixés au bottier 1 par leur axe ou partie centrale 18, leur partie externe 19 étant adaptée à rouler sur les collerettes 4 des broches 2 et 3. Chaque broche est centrée par trois roulements; il est prévu cinq roulements dont un roulement commun aux deux broches. To ensure the centering of the pins, bearings 17 are fixed to the case 1 by their axis or central part 18, their external part 19 being adapted to roll on the flanges 4 of the pins 2 and 3. Each pin is centered by three bearings; five bearings are provided, including a bearing common to the two spindles.
Chacune des broches 2 et 3 comporte un alésage axial 20 muni d'un épaulement 21 dans lequel sont per cés des trous taraudés 22 pour la fixation de l'outil (voir Figures 4 et 5). La broche 2 de fraisage comporte trois trous taraudés 22 alors que la broche 3 de rodage n'en comporte que deux. Each of the pins 2 and 3 has an axial bore 20 provided with a shoulder 21 in which are tapped holes 22 for fixing the tool (see Figures 4 and 5). The milling spindle 2 has three tapped holes 22 while the lapping spindle 3 has only two.
La fraise 23 est taillée de manière à présenter deux dentures coniques 24 et 25 sur ses deux faces opposées avec un perçage axial 26 qui pourrait éventuellement comporter une butée limitant la course; elle comporte en outre un épaulement 27 propre à s'engager dans l'alésage axial 20 de la broche 2. Cet épaulement 27 définit une bordure qui contient trois perçages 28 munis de logements 29 pour des têtes de vis 40, qui correspondent aux trois trous taraudés 22 de la broche de fraisage. The cutter 23 is cut so as to have two conical teeth 24 and 25 on its two opposite faces with an axial bore 26 which could possibly include a stop limiting the stroke; it further comprises a shoulder 27 suitable for engaging in the axial bore 20 of the spindle 2. This shoulder 27 defines an edge which contains three holes 28 provided with housings 29 for screw heads 40, which correspond to the three holes threaded 22 of the milling spindle.
La broche de rodage 3, identique par ailleurs à la broche de fraisage, ne comporte que deux trous taraudés 22 diamétralement opposés. The lapping spindle 3, which is also identical to the milling spindle, has only two diametrically opposed tapped holes 22.
Le rodoir 30 se compose d'une plaque rectangulaire 30 abrasive sur ses deux faces opposées. Il est fixé à la broche 3 à l'aide d'un anneau de fixation 31 engagé dans l'alésage axial 20 de la broche 3 et comportant un trou axial 32 pour le passage de l'électrode à roder L'anneau 31 comporte deux trous 33 diamétralement opposés, munis de logements 29 pour des têtes de vis 40 et correspondant aux deux trous 22 de la broche 3. Il comporte en outre un fraisage 34 diamétral, d'une profondeur inférieure à l'épaisseur du rodoir, compris entre les deux trous~33, sur la face opposée aux logements 29 des tettes de vis. The lapper 30 consists of a rectangular abrasive plate 30 on its two opposite faces. It is fixed to spindle 3 using a fixing ring 31 engaged in the axial bore 20 of spindle 3 and comprising an axial hole 32 for the passage of the lapping electrode The ring 31 has two diametrically opposite holes 33, provided with housings 29 for screw heads 40 and corresponding to the two holes 22 of the spindle 3. It further comprises a diametric milling 34, of a depth less than the thickness of the lapping, between the two holes ~ 33, on the face opposite to the housings 29 of the screw caps.
Le rodoir est disposé entre l'anneau 31 et la broche 3 de sorte que le serrage des vis porte sur le rodoir qui est ainsi immobilisé dans son logement. The lapping is arranged between the ring 31 and the spindle 3 so that the tightening of the screws bears on the lapping which is thus immobilized in its housing.
En variante sur la Figure 6, le mouvement de rotation alternative des broches est engendré par un moteur électrique 35 entraînant une manivelle 36 reliée à la biellette 14 par un levier 37 articulé aux deux bouts en 38 et 39. As a variant in FIG. 6, the alternating rotational movement of the pins is generated by an electric motor 35 driving a crank 36 connected to the link 14 by a lever 37 articulated at the two ends at 38 and 39.
La présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. The present invention should not be considered as limited to the embodiment described and shown, but covers, on the contrary, all variants.
