Description

Dispositif de test des outils d'usinage de vilebrequin Test device for crankshaft machining tools
L'invention concerne le domaine de l'usinage par galetage, par exemple des portées cylindriques de vilebrequins. L'invention concerne notamment un dispositif de test des outils de galetage.The invention relates to the field of roller milling, for example cylindrical bearing surfaces of crankshafts. The invention relates in particular to a device for testing roller burnishing tools.
Les machines de galetage permettent la réalisation des congés de chaque côté d'une portée cylindrique d'un vilebrequin. Chaque portée cylindrique d'un vilebrequin est pressée d'une part entre deux galets et d'autre part entre deux roues de support, disposées à l'opposé des galets. L'axe de rotation des galets est incliné par rapport à l'axe de rotation du vilebrequin, les galets s'appuyant de chaque côté de la portée cylindrique d'un vilebrequin. La pression exercée par les galets permet le galetage des congés de chaque côté d'une portée cylindrique d'un vilebrequin. Une roue d'appui exerce une force de pression sur les galets qui sont maintenus en place par une cage. Les galets roulent à la fois sur la portée de vilebrequin et sur la roue d'appui, lorsque le vilebrequin est mis en rotation. La mise en rotation du vilebrequin est réalisée par la machine de galetage qui comprend des moyens de maintien et d'entraînement du vilebrequin.The burnishing machines allow the realization of the leaves on each side of a cylindrical bearing of a crankshaft. Each cylindrical seat of a crankshaft is pressed on the one hand between two rollers and on the other hand between two support wheels, arranged opposite the rollers. The axis of rotation of the rollers is inclined relative to the axis of rotation of the crankshaft, the rollers bearing on each side of the cylindrical bearing surface of a crankshaft. The pressure exerted by the rollers allows the burnishing of the leaves on each side of a cylindrical bearing surface of a crankshaft. A support wheel exerts a pressing force on the rollers which are held in place by a cage. The rollers roll on both the crankshaft bearing and the support wheel, when the crankshaft is rotated. The rotation of the crankshaft is carried out by the roller burnishing machine which comprises means for holding and driving the crankshaft.
L'opération de galetage des vilebrequins est très coûteuse. Afin de réduire le coût de l'opération, l'optimisation des outils est nécessaire pour garantir ou améliorer la durée de vie des outils et une usure stable des outils. D'une part, l'usure des outils doit être contrôlée pour garantir la qualité d'usinage et d'autre part la durée de vie de l'outil est optimisée pour rentabiliser l'outil au maximum et conserver une qualité minimum de galetage.The burnishing operation of the crankshafts is very expensive. In order to reduce the cost of the operation, tool optimization is necessary to guarantee or improve tool life and stable tool wear. On the one hand, tool wear must be checked to ensure machining quality and, on the other hand, tool life is optimized to maximize the profitability of the tool and maintain a minimum roller burnishing quality.
Un problème technique concerne la réalisation des tests sur les outils de galetage. En effet pour garantir une durée de vie plus stable et plus importante, des essais de durée de vie sont nécessaires. De même les éventuelles modifications réalisées sur les outils de galetage nécessitent au moins une validation avant que ces outils soient utilisés dans une chaîne d'usinage. Actuellement les essais réalisés sur les outils de galetage, nécessitent qu'une étape de validation préliminaire soit réalisée dans une chaîne de production. L'agencement de la chaîne de production doit donc être modifié ce qui est pénalisant en terme de productivité. De plus la mise en œuvre des tests nécessite une reconfiguration de la chaîne de production qui est très longue à mettre en œuvre, d'autant plus que plusieurs tests différents sont souvent nécessaires. D'autre part les essais sont réalisés sur des vilebrequins qui sont perdus pour la vente. Le nombre de vilebrequins perdus est d'autant plus important que les vilebrequins se dégradent beaucoup plus vite que les outils de galetage et que plusieurs vilebrequins sont nécessaires pour tester l'usure complète d'un jeu d'outils de galetage. Ces essais des outils de galetage sont donc doublement pénalisant pour la productivité.A technical problem concerns the realization of tests on burnishing tools. In order to guarantee a longer and more stable lifetime, life tests are necessary. Similarly, any modifications made to the roller burnishing tools require at least one validation before these tools are used in a machining line. Currently the tests carried out on the burnishing tools, require that a preliminary validation stage be carried out in a production line. The layout of the production line must therefore be modified, which is penalizing in terms of productivity. Moreover the implementation of the tests requires a reconfiguration of the production chain which is very long to implement, especially since several different tests are often necessary. On the other hand the tests are carried out on crankshafts which are lost for sale. The number of crankshafts lost is all the more important as the crankshafts degrade much faster than the burnishing tools and several crankshafts are needed to test the complete wear of a set of burnishing tools. These tests roller burners are doubly penalizing for productivity.

Les chemins (22) de roulement à galets (2) ont des positions déterminées correspondant à celles des congés de raccordement réalisés sur un vilebrequin, dans la machine de galetage, ces positions étant repérées relativement à un plan perpendiculaire à l'axe (10) de rotation du dispositif (1 ) de test. En considérant une section selon un plan passant par l'axe (10) de rotation du dispositif (1 ) de test, les chemins (22) de roulement à galets (2) comportent un profil en arrondi pour accueillir les galets (2). Le profil en arrondi des chemins (22) de roulement à galets (2) apparaît notamment sur chacune des figures 1 , 2 et 3. La matière dans laquelle sont réalisés les bagues (20, 21 ) de roulement sur lesquelles sont réalisés les chemins (22) de roulement à galets (2), est de dureté identique à celle de la matière utilisée pour réaliser les roues (3) d'appui de la machine de galetage. Le diamètre (D22) des chemins (22) de roulement à galets (2) est choisi identique au diamètre de la portée cylindrique usinée dans la machine. L'avantage par rapport à l'utilisation d'un vilebrequin pour réaliser un test des galets (2), est que les chemins (22) de roulement à galets selon l'invention ne sont pas destinés à être déformés par les galets (2). Les galets (2) subissant une pression similaire à la pression dans les conditions d'usinage, l'usure des galets (2) ou de la roue (3) d'appui sera identique. Un chemin (22) de roulement à galets permettra le test d'usure complet d'au moins un jeu de galets (2) associés à une roue (3) d'appui. Dans un exemple de test, la machine de galetage entraîne le dispositif (1 ) de test selon l'invention, jusqu'à ce qu'un galet (2) ou la roue (3) d'appui ou la bague (20) de roulement pour les galets se brise. Les bagues (20, 40) de roulement sont facilement démontables et sont par exemple remplacées avant le début d'un test.(2) of the roller burnishing machine. The roller bearing tracks (22) (2) have determined positions corresponding to those of the connecting fillet made on a crankshaft, in the rolling machine, these positions being marked relative to a plane perpendicular to the axis (10) of rotation of the device (1) test. Considering a section along a plane passing through the axis (10) of rotation of the test device (1), the roller bearing paths (22) (2) comprise a rounded profile to accommodate the rollers (2). The rounded profile of roller bearing tracks (22) (2) appears in particular in each of FIGS. 1, 2 and 3. The material in which the bearing rings (20, 21) are formed on which the paths are made ( 22) roller bearing (2), is of identical hardness to that of the material used to make the wheels (3) bearing of the roller burnishing machine. The diameter (D22) of the roller bearing paths (22) is chosen to be identical to the diameter of the cylindrical bearing surface machined in the machine. The advantage over the use of a crankshaft to perform a test of the rollers (2) is that the roller bearing paths (22) according to the invention are not intended to be deformed by the rollers (2). ). The rollers (2) undergoing pressure similar to the pressure in the machining conditions, the wear of the rollers (2) or the wheel (3) bearing will be identical. A roller bearing path (22) will allow the complete wear test of at least one set of rollers (2) associated with a bearing wheel (3). In an exemplary test, the roller burnishing machine drives the test device (1) according to the invention, until a roller (2) or the support wheel (3) or the ring (20) of rolling for the pebbles breaks. The bearing rings (20, 40) are easily removable and are, for example, replaced before the start of a test.
Le dispositif (1 ) de test selon l'invention comprend des chemins (42) de roulement pour les roues (4) de support. Ces chemins (42) de roulement sont en appui sur les roues (4) de support de la machine de galetage. Les chemins (42) de roulement pour les roues (4) de support ont des positions déterminées, correspondant à celles des portées cylindriques du vilebrequin usiné dans la machine de galetage, ces positions étant repérées relativement à un plan perpendiculaire à l'axe (10) de rotation du dispositif (1 ) de test. Les chemins (42) de roulement pour les roues (4) de support ont une forme cylindrique dont l'axe de symétrie correspond à l'axe (10) de rotation du dispositif (1 ) de test. Le profil des chemins (42) de roulement pour les roues (4) de support dans une section selon un plan passant par l'axe (10) de rotation du dispositif (1 ) est donc un profil droit. Ce profil apparaît notamment sur chacune des figures 1 , 2 et 3.The test device (1) according to the invention comprises bearing tracks (42) for the support wheels (4). These bearing paths (42) bear on the wheels (4) for supporting the rolling machine. The bearing paths (42) for the support wheels (4) have predetermined positions, corresponding to those of the cylindrical bearings of the crankshaft machined in the rolling machine, these positions being marked relative to a plane perpendicular to the axis (10). ) of rotation of the test device (1). The bearing tracks (42) for the support wheels (4) have a cylindrical shape of which the axis of symmetry corresponds to the axis (10) of rotation of the device (1) test. The profile of the rolling paths (42) for the support wheels (4) in a section along a plane passing through the axis (10) of rotation of the device (1) is therefore a straight profile. This profile appears in particular in each of Figures 1, 2 and 3.
Le dispositif (1 ) de test selon la présente invention, comporte des moyens de fixation et d'entraînement par la machine de galetage, identiques à ceux d'un vilebrequin ou s'adaptant à tout type de machine de galetage. De plus le dispositif (1 ) de test comporte des chemins (22, 42) de roulement positionnés en face des outils de galetage, ce qui permet au dispositif (1 ) de test selon l'invention d'être positionné dans tout type de machine de galetage, pour le test de la machine. Des outils et des machines de galetage sont par exemple décrit dans les documents suivants :The device (1) for testing according to the present invention comprises means for fixing and driving by the rolling machine, identical to those of a crankshaft or adapting to any type of roller burnishing machine. In addition, the test device (1) comprises rolling paths (22, 42) positioned in front of the burnishing tools, which enables the test device (1) according to the invention to be positioned in any type of machine. roller burnishing, for testing the machine. Tools and roller burnishing machines are described, for example, in the following documents:
- la demande de brevet US 2002/0020202 décrit, par exemple, plusieurs outils de galetage associés à des cages de maintien en flottement des galets ;the patent application US 2002/0020202 describes, for example, several roller burnishing tools associated with cages for floating the rollers;
- le brevet US 6,253,590 décrit, par exemple, différents mode de réalisation d'un outil de galetage, comportant une partie supérieure supportant les galets dans une cage et une partie inférieure comportant deux roues de support de la portée cylindrique à usiner ;US Pat. No. 6,253,590 describes, for example, different embodiments of a roller burnishing tool, comprising an upper part supporting the rollers in a cage and a lower part comprising two support wheels of the cylindrical bearing surface to be machined;
- la demande de brevet WO 2005/063438 décrit, par exemple, une machine de galetage comprenant deux bras disposés de part et d'autre de la portée de vilebrequin et un roue de guidage axial pour éviter une collision entre les outils de galetage et des éléments du vilebrequin ;the patent application WO 2005/063438 describes, for example, a roller burnishing machine comprising two arms arranged on either side of the crankshaft bearing and an axial guide wheel to prevent a collision between the roller tools and crankshaft elements;
L'utilisation du dispositif (1 ) de test selon l'invention permet donc la réalisation de tests de nombreuses configurations, indépendamment de la chaîne de production. Les configurations de test ne sont pas figées. La réalisation de tests nombreux et variés est ainsi facilitée. Des modifications pour des améliorations des outils de tests sont donc facilitées. L'amélioration des outils de test concerne par exemple la garanti d'une durée de vie plus stable et plus importante des outils de galetage. Le dispositif (1 ) de test selon l'invention dont la structure sera détaillée par la suite, est réalisable avec des éléments simples et bon marché et de plus le dispositif (1 ) de test est fabriqué et puis monté dans une machine de galetage, indépendamment de la chaîne de fabrication des vilebrequins. Les tests sont par exemple réalisés sur une machine annexe, en dehors de la chaîne de production des vilebrequins. Grâce au dispositif de test selon l'invention, aucun vilebrequin n'est nécessaire par exemple pour tester la durée de vie ou la vitesse d'usure des outils de galetage. De plus un test complet nécessite un seul dispositif (1 ) de test selon l'invention. La lubrification est réalisée de la même façon que pour le galetage d'un vilebrequin. Les dimensions du dispositif (1 ) de test selon l'invention, étant voisines de celles d'un vilebrequin, les conditions pour les tests sont identiques aux conditions dans lesquelles le galetage d'un vilebrequin est réalisé.The use of the test device (1) according to the invention therefore makes it possible to carry out tests of numerous configurations, independently of the production line. Test configurations are not fixed. The realization of numerous and varied tests is thus facilitated. Modifications for improvements to the testing tools are therefore facilitated. The improvement of the test tools concerns, for example, the guarantee of a longer and more stable life of the burnishing tools. The test device (1) according to the invention, the structure of which will be detailed later, can be realized with simple and inexpensive elements and the test device (1) is manufactured and then mounted in a rolling machine, regardless of the crankshaft production line. The tests are for example performed on a machine annex, outside the production line of crankshafts. Thanks to the test device according to the invention, no crankshaft is necessary for example to test the service life or the wear speed of the burnishing tools. In addition, a complete test requires a single test device (1) according to the invention. The lubrication is carried out in the same way as for the burnishing of a crankshaft. Since the dimensions of the test device (1) according to the invention are close to those of a crankshaft, the conditions for the tests are identical to the conditions in which the rolling of a crankshaft is carried out.
Un mode de réalisation du dispositif (1 ) de test représenté à la figure 1 va maintenant être décrit. De manière non limitative, dispositif (1 ) de test est adapté à un outil de galetage d'un vilebrequin comportant une ou plusieurs portées cylindriques, pour lequel les outils de galetage d'une portée cylindrique, sont testés simultanément ou successivement.An embodiment of the test device (1) shown in FIG. 1 will now be described. In a nonlimiting manner, test device (1) is adapted to a roller burnishing tool of a crankshaft having one or more cylindrical bearing surfaces, for which the rolling tools of a cylindrical bearing surface, are tested simultaneously or successively.
Un arbre (6) principal d'axe de révolution identique à l'axe (10) de rotation du dispositif (1 ) de test se prolonge par deux extrémités filetées (61 ) ou est lié à des pièces rapportées comprenant des extrémités filetées. L'arbre principal a un diamètre (D2) supérieur au diamètre (D1 ) de ses extrémités (61 ). Le diamètre des parties filetées s'adapte à des écrous (7, 8, 9) de serrage.A main shaft (6) of axis of revolution identical to the axis (10) of rotation of the test device (1) is extended by two threaded ends (61) or is connected to inserts comprising threaded ends. The main shaft has a diameter (D2) greater than the diameter (D1) of its ends (61). The diameter of the threaded parts fits with tightening nuts (7, 8, 9).
De manière non limitative, une collerette (62) ou un épaulement est disposé sur l'arbre (6) principal. Des bagues (20, 40) de roulement sont disposées sur l'arbre (6) principal. De manière non limitative, les bagues (20, 40) sont montées serrées sur l'arbre (6) principal. De manière non limitative, les bagues (20, 40) de roulement sont en appui contre l'épaulement (62). L'épaulement (62) permet un appui axial des bagues (20, 40) de roulement. Les éléments (20, 40) de roulement sont ainsi rendus solidaires de l'arbre (6) principal. De manière non limitative, l'épaulement est réalisé en bout d'arbre ou par la collerette.In a nonlimiting manner, a flange (62) or a shoulder is arranged on the main shaft (6). Bearing rings (20, 40) are arranged on the main shaft (6). In a nonlimiting manner, the rings (20, 40) are tightly mounted on the main shaft (6). In a nonlimiting manner, the bearing rings (20, 40) bear against the shoulder (62). The shoulder (62) allows axial support of the bearing rings (20, 40). The rolling elements (20, 40) are thus secured to the main shaft (6). In a nonlimiting manner, the shoulder is made at the end of the shaft or by the collar.
De manière non limitative, un écrou (7) réalise le serrage des bagues (20, 40) de roulement d'un côté de l'arbre (6) principal et un double écrou (8, 9) réalise le serrage des bagues (20, 40) de roulement de l'autre côté de l'arbre (6).In a nonlimiting manner, a nut (7) clamps the bearing rings (20, 40) on one side of the main shaft (6) and a double nut (8, 9). effecting the tightening of the bearing rings (20, 40) on the other side of the shaft (6).
Comme représenté à la figure 1 , le chemin (22) de roulement à galetsAs shown in FIG. 1, the roller bearing path (22)
(2) est réalisé selon un diamètre (D22) supérieur à celui du diamètre (D42) du chemin (42) de roulement pour les roues (4) de support. Les bagues (20) de roulement pour les galets (2), sont réalisées, de manière non limitative, symétriques pour faciliter leur fabrication. Ainsi cette bague (20) de roulement sert autant pour un galet situé à droite que pour un galet situé à gauche, voire pour deux galets.(2) is made according to a diameter (D22) greater than that of the diameter (D42) of the path (42) of rolling for the wheels (4) support. The bearing rings (20) for the rollers (2) are non-limitingly symmetrical to facilitate their manufacture. Thus this ring (20) of rolling serves both for a roller on the right than for a roller on the left, or for two rollers.
Un mode de réalisation, prévoit l'utilisation de pièces déjà existantes. Ainsi les bagues (20) de roulement pour les galets (2) sont réalisées par des roues (3) d'appui de la machine de galetage et les bagues (40) de roulement pour les roues (4) de support, sont réalisées par des entretoises dont le diamètre extérieur est inférieur ou égal au diamètre extérieur latéral des rouesOne embodiment provides for the use of already existing parts. Thus the bearing rings (20) for the rollers (2) are formed by bearing wheels (3) of the rolling machine and the bearing rings (40) for the support wheels (4) are produced by spacers whose outer diameter is less than or equal to the lateral outer diameter of the wheels
(3) d'appui. Ce mode de réalisation a l'avantage d'utiliser des pièces déjà existantes, ce qui permet une réalisation du dispositif (1 ) de test selon l'invention immédiate, ne nécessitant pas l'usinage de nouvelles pièces, à l'exception de l'arbre (6) principal. Dans ce mode de réalisation, la bague (20) de roulement pour les galets (2), qui est une roue d'appui, aura donc une vitesse d'usure quasiment identique à la roue (3) d'appui de la machine de galetage. Un test de durée de vie des outils de galetage se termine par exemple, par l'écaillage d'un galet (2) ou d'une roue (3) d'appui. De plus ce mode de réalisation dans lequel des roues (3) d'appui sont utilisées comme éléments de roulement pour les galets (2) permet d'assurer la compatibilité avec la machine de galetage, concernant la dureté et la taille des éléments (20) de roulement.(3) support. This embodiment has the advantage of using already existing parts, which allows an embodiment of the device (1) for testing according to the instant invention, not requiring the machining of new parts, with the exception of main shaft (6). In this embodiment, the bearing ring (20) for the rollers (2), which is a support wheel, will therefore have a wear speed that is almost identical to the bearing wheel (3) of the machine. burnishing. A test of life of the burnishing tools ends for example, by peeling a roller (2) or a wheel (3) support. Moreover this embodiment in which bearing wheels (3) are used as rolling elements for the rollers (2) makes it possible to ensure compatibility with the rolling machine, concerning the hardness and the size of the elements (20). ).
Dans une variante de réalisation, comme représenté à la figure 2, les bagues (20, 40) de roulement sont maintenues solidaires en rotation de l'arbre (6) principal par une clavette (1 1 ). De manière non limitative, l'arbre (6) principal est associé à une ou plusieurs clavettes (1 1 ). Les clavettes sont utilisées, de manière non limitative, pour un arbre supportant un nombre important de dispositifs de roulement. Dans une variante de réalisation, comme représenté à la figure 3, les bagues (21 ) de roulement pour les galets (2) ne comportent qu'un chemin de roulement à galets (2). Une entretoise (12) de positionnement est combinée aux bagues (41 , 21 ) de roulement pour ajuster la position des chemins (22, 42) de roulement.In an alternative embodiment, as shown in Figure 2, the bearing rings (20, 40) are held integral in rotation with the main shaft (6) by a key (1 1). Without limitation, the main shaft (6) is associated with one or more keys (1 1). The keys are used, without limitation, for a shaft supporting a large number of rolling devices. In an alternative embodiment, as shown in Figure 3, the bearing rings (21) for the rollers (2) comprise only a rolling track roller (2). A positioning spacer (12) is combined with the bearing rings (41, 21) to adjust the position of the rolling paths (22, 42).
Dans une variante de réalisation, comme représenté à la figure 3, le chemin (42) de roulement pour les roues (4) de support est situé à la même hauteur que la partie basse de le chemin de roulement (22) pour les galets (2). La bague de roulement (21 ) comprend un diamètre (D22) identique au diamètre (D42) de la bague (41 ) de roulement pour les roues (4) de support.In an alternative embodiment, as shown in FIG. 3, the bearing path (42) for the support wheels (4) is situated at the same height as the lower part of the race (22) for the rollers ( 2). The bearing ring (21) comprises a diameter (D22) identical to the diameter (D42) of the bearing ring (41) for the support wheels (4).
Le dispositif (1 ) de test, représenté à la figure 1 , est adapté à la machine de galetage et permet de tester le galetage simultanément d'une pluralité de portées cylindriques, mais le dispositif (1 ) de test selon l'invention est aussi adapté au test des outils de galetage pour une seule portée cylindrique de vilebrequin.The test device (1), shown in FIG. 1, is adapted to the roller burnishing machine and makes it possible to test the burnishing simultaneously of a plurality of cylindrical bearing surfaces, but the test device (1) according to the invention is also suitable for testing roller tools for a single cylindrical crankshaft bearing.
Il doit être évident pour les personnes versées dans l'art que la présente invention permet des modes de réalisation sous de nombreuses autres formes spécifiques sans l'éloigner du domaine d'application de l'invention comme revendiqué. Par conséquent, les présents modes de réalisation doivent être considérés à titre d'illustration, mais peuvent être modifiés dans le domaine défini par la portée des revendications jointes, et l'invention ne doit pas être limitée aux détails donnés ci-dessus.
