Description

PROCEDE ET APPAREIL DE NETTOYAGE DE MASQUES DE PROTECTION DE FACE SUPERIEURE DE CARTER CYLINDRES  METHOD AND APPARATUS FOR CLEANING UPPER FACE PROTECTION MASKS OF CYLINDER HOUSING
La présente invention se rapporte à la préparation des carter-cylindres de moteurs à combustion interne. The present invention relates to the preparation of the crankcase of internal combustion engines.
Plus précisément, elle concerne le nettoyage des masques de protection de face supérieure de carter cylindres de moteur, à l'issue des opérations de projection thermique de particules sur les surfaces intérieures de fûts de cylindre.  More specifically, it relates to the cleaning of the protective masks on the upper side of the crankcase engine cylinders, after the thermal projection operations of particles on the inner surfaces of cylinder barrels.
Cette invention a pour objet un procédé de nettoyage d'un masque de protection de face supérieure de carter cylindres, utilisé lors de la projection thermique de revêtements à l'intérieur des fûts de cylindre de moteurs.  The present invention relates to a method of cleaning a cylinder cover upper face protection mask which is used in the thermal spraying of coatings inside the engine cylinder drums.
Elle a également pour objet un appareil de nettoyage rotatif de masques de protection cylindriques de face supérieure de carter-cylindres utilisés lors de la projection thermique de de revêtements dans les fûts de cylindre de moteurs.  It also relates to a rotary cleaning apparatus cylinders protective cylinders on the upper side of crankcase used during the thermal spraying of coatings in the engine cylinder drums.
La préparation des surfaces internes de fûts de cylindre de moteur passe par l'application d'un revêtement, le plus souvent projeté thermiquement à l'intérieur du fût. Cette projection est orientée par des buses de projection en direction de la surface intérieure des cylindres. Elle génère cependant une diffusion désordonnée de particules projetées dans d'autres directions, notamment vers la face supérieure du carter-cylindre, où elle n'est pas souhaitée. La pulvérisation nécessite la disposition d'un masque de protection, généralement de forme cylindrique, sur la face supérieure du carter cylindre.  The preparation of the inner surfaces of engine cylinder drums passes through the application of a coating, usually sprayed thermally inside the barrel. This projection is oriented by projection nozzles towards the inner surface of the rolls. However, it generates a disordered diffusion of particles projected in other directions, especially towards the upper face of the crankcase, where it is not desired. Spraying requires the provision of a protective mask, generally of cylindrical shape, on the upper face of the cylinder block.
Après opération, les masques de protection sont nettoyés pour éliminer la matière (« oversparay résiduel ») pulvérisée sur celle-ci. Ils sont ensuite stockés en vue d'être réutilisés. Actuellement, le nettoyage des masques s'effectue par ébavurage à haute pression (HP) . Mais la qualité de l' ébavurage HP n'est pas constante, et son temps de cycle est long, car il faut reprendre manuellement le nettoyage de la plupart des masques. Ces opérations engendrent des coûts supplémentaires. Pour les réduire, il faut augmenter la durée de vie des masques, et réduire leur temps de nettoyage. After the operation, the protective masks are cleaned to remove the material ("residual oversparay") sprayed on it. They are then stored for reuse. Currently, masks are cleaned by high-pressure deburring (HP). But the quality of the deburring HP is not constant, and its cycle time is long, because it is necessary to manually resume the cleaning of most masks. These operations generate additional costs. To reduce them, it is necessary to increase the life of the masks, and to reduce their cleaning time.
Les objectifs de performance dans ce domaine sont les suivants :  The performance objectives in this area are:
• obtenir un niveau optimal de qualité d' état de surface du masque,  • obtain an optimal level of surface quality of the mask,
• augmenter la durée de vie des masques, et  • increase the life of the masks, and
• réduire le temps de nettoyage des masques.  • reduce the cleaning time of the masks.
Cependant, l'adhérence des bavures sur les masques est telle, que l'opération requiert des pressions très élevées, de l'ordre de 50 Bars (5MPa) . Dans ces conditions, on ne sait pas aujourd'hui industrialiser à moindre coût le nettoyage des masques avec les techniques d'ébavurage à haute pression.  However, the adhesion of the burrs on the masks is such that the operation requires very high pressures, of the order of 50 Bars (5MPa). Under these conditions, it is not known today to industrialize at a lower cost the cleaning of masks with high-pressure deburring techniques.
La présente invention vise à réduire le temps de cycle des masques de protection de face supérieure de cylindre, tout en garantissant leur propreté pour la pulvérisation des fûts de cylindre suivants.  The present invention aims to reduce the cycle time of the cylinder top face protection masks, while ensuring their cleanliness for spraying the following cylinder drums.
Dans ce but, elle propose de réaliser le nettoyage avec un appareil rotatif opérant simultanément le nettoyage du plan d'appui du masque sur la face supérieure du carter-cylindres, et du bord intérieur du masque cylindrique en appui sur le carter- cylindre .  For this purpose, it proposes to carry out the cleaning with a rotary apparatus simultaneously operating the cleaning of the support plane of the mask on the upper face of the crankcase, and the inner edge of the cylindrical mask resting on the crankcase.
De préférence, l'appareil réalise aussi simultanément le nettoyage d'une gouttière circulaire ménagée dans la masse du masque à proximité de don bord intérieur.  Preferably, the apparatus also simultaneously performs the cleaning of a circular gutter formed in the mass of the mask near don inner edge.
Cet appareil est composé d'un porte-outil entraîné en rotation, qui présente des logements pour des outils dédiés respectivement au nettoyage du plan d'appui du masque sur la face supérieure du carter-cylindres, et du bord intérieur du masque cylindrique en appui sur le carter-cylindre, et pour des outils dédiés au nettoyage d'une gouttière circulaire ménagée dans la masse du masque à proximité de son bord intérieur.  This apparatus is composed of a rotated tool holder, which has housings for tools dedicated respectively to the cleaning of the support plane of the mask on the upper face of the crankcase, and the inner edge of the cylindrical mask in support on the crankcase, and for tools dedicated to the cleaning of a circular groove formed in the mass of the mask near its inner edge.
La présente invention sera mieux comprise à la lecture suivante de la description d'un mode de réalisation non limitatif de celle-ci, en se reportant aux dessins annexés, sur lesquels : les figures 1A à 1D sont des vues de dessus, en élévation, en coupe et en perspective, d'un masque, The present invention will be better understood on reading the following description of a non-limiting embodiment thereof, with reference to the appended drawings, in which: FIGS. 1A to 1D are views from above, in elevation, in section and in perspective, of a mask,
la figure 2 montre un masque après utilisation, la figure 3 met en évidence les zones à nettoyer, - la figure 4 illustre un premier mode de réalisation de tête amovible pour outil à plaquettes ou à brosses porte-outils, avec serrage par vis, des plaquettes ou des brosses,  FIG. 2 shows a mask after use, FIG. 3 highlights the zones to be cleaned; FIG. 4 illustrates a first embodiment of a removable head for a tool with wafers or tool brushes, with screw tightening, pads or brushes,
la figure 5 illustre un deuxième mode de réalisation de tête amovible, avec des cartouches porte-brosses ou porte- plaquettes,  FIG. 5 illustrates a second embodiment of a removable head, with brush-holder cartridges or toolholders,
les figures 6 et 7 , montrent les têtes amovibles des figures 4 et 5 montées sur leur porte-outil, et  Figures 6 and 7 show the removable heads of Figures 4 and 5 mounted on their tool holder, and
la figure 8 montre une tête amovible en position 20 de travail sur un masque de protection.  Figure 8 shows a removable head in the working position on a protective mask.
Le masque de protection des figures 1A à 1D se dispose sur la face supérieure d'un carter cylindre sur chaque ouverture de fût de cylindre. Son plan d'appui la, repose autour de l'ouverture d'un fût de cylindre, pour empêcher la projection du produit de revêtement pulvérisé à haute température en direction des surfaces intérieures des fûts, sur la face supérieure du carter-cylindre, Comme indiqué ci-dessus, les masques 1 doivent être nettoyés, pour éliminer l'« overspray » résiduel sur leur face inférieure la avant de pouvoir être réutilisés. En se référant à l'exemple de la figure 2 et à l'agrandissement de la figure 3, les zones à nettoyer sur la face inférieure la du masque, sont localisées sur son plan d'appui zl, sa gouttière z2, et son bord intérieur z3.  The protective mask of FIGS. 1A to 1D is provided on the upper face of a cylinder block on each cylinder drum opening. Its support plane la, rests around the opening of a barrel of cylinder, to prevent the projection of the product of coating sprayed at high temperature towards the inner surfaces of the barrels, on the upper face of the crankcase, As indicated above, the masks 1 must be cleaned, to remove the residual "overspray" on their underside before they can be reused. Referring to the example of Figure 2 and the enlargement of Figure 3, the areas to be cleaned on the lower face of the mask, are located on its support plane zl, its gutter z2, and its edge interior z3.
La tête porte-outil 2 de la figure 4, est une tête amovible. Elle porte trois outils de nettoyage différents 3, 4, 6, serrés en leur centre par des vis (non représentées), dont on voit les trous de serrage 7 :  The tool head 2 of Figure 4, is a removable head. It carries three different cleaning tools 3, 4, 6, tight in their center by screws (not shown), which we see the clamping holes 7:
-un premier outil 3 pour le nettoyage du plan d'appui zl, -un deuxième outil 4 pour le nettoyage de la gouttière z2, - un troisième outil 6 pour le nettoyage du bord intérieur du masque z3. Les trois outils 3, 4, 6 de la tête amovible 2, peuvent être des brosses, des plaquettes, ou autres. La tête 2 vient se fixer sur un porte-outil 8 (tel que celui des figures 6 ou 7), par une queue cylindrique 10 présentant par exemple une zone aplatie 10a, facilitant son vissage. a first tool 3 for cleaning the support plane z1, a second tool 4 for cleaning the gutter z2, a third tool 6 for cleaning the inner edge of the mask z3. The three tools 3, 4, 6 of the removable head 2 may be brushes, wafers, or others. The head 2 is fixed on a tool holder 8 (such as that of Figures 6 or 7) by a cylindrical shank 10 having for example a flattened area 10a, facilitating its screwing.
Dans le mode de réalisation de la figure 5, on retrouve une tête porte-outil amovible 2 du même type, avec les trois outils 3, 4, 6 de la figure 4. Toutefois, ces derniers ne sont plus vissés directement dans des logements sur la tête 2, mais sont montés sur des cartouches 3a, 4a, 6a, elles-mêmes fixées en leur centre par des vis 7, dans des logements sur la tête 2.  In the embodiment of Figure 5, there is a removable tool head 2 of the same type, with the three tools 3, 4, 6 of Figure 4. However, they are no longer screwed directly into housing on the head 2, but are mounted on cartridges 3a, 4a, 6a, themselves fixed in their center by screws 7, in housings on the head 2.
Le porte-outil 8 de la figure 6 présente une extrémité d'attachement 11 sur une machine d'entraînement en rotation. Il porte la tête amovible 2 de la figure 4, où les outils 3, 4, 6 sont vissés directement dans des logements sur celle-ci. Sur la figure 7 le porte- outil reçoit la tête amovible 2 à cartouches 3a, 4a, 6a, de la figure 5.  The tool holder 8 of Figure 6 has an attachment end 11 on a rotary drive machine. It carries the removable head 2 of Figure 4, where the tools 3, 4, 6 are screwed directly into housings thereon. In FIG. 7, the tool holder receives the removable cartridge head 2 3a, 4a, 6a of FIG.
Enfin, la figure 8, montre un mode de réalisation particulier de l'invention, avec seulement deux brosses, dont une première brosse 3 pour nettoyer la face d'appui la du masque, et une deuxième une brosse unique 4, 6, pour nettoyer sa gouttière et son bord intérieur.  Finally, Figure 8 shows a particular embodiment of the invention, with only two brushes, including a first brush 3 to clean the support face of the mask, and a second brush 4, 6, to clean its gutter and its inner edge.
Contrairement aux exemples illustrés par les schémas, le porte-outil 8 peut être dépourvu de de tête amovible. Dans ce cas, les outils 3, 4, 6, ou leurs cartouches de montage 3a, 4a, 6a sont vissés directement sur le porte-outil 8.  Unlike the examples illustrated by the diagrams, the tool holder 8 may be devoid of removable head. In this case, the tools 3, 4, 6, or their mounting cartridges 3a, 4a, 6a are screwed directly onto the tool holder 8.
En résumé, le nouveau procédé de nettoyage d'un masque cylindrique de protection d'une face supérieure de carter- cylindres lors de la projection thermique des fûts de cylindre de moteurs, est mis en œuvre avec un appareil rotatif composé d'un corps porte-outil, avec ou sans tête amovible, qui présente des logements pour y insérer des outils à trou par leur centre, ou bien des cartouches porte-outils à trou par leur centre. Ces outils peuvent être des plaquettes de coupe, des brosses, ou une combinaison des deux. Les porte-outils peut recevoir ou non une tête amovible de support d'outils. Les outils sont vissés directement dans leurs logements sur les porte-outils ou sur la tête amovible, ou bien ils sont montés dans des cartouches, elles- mêmes vissées dans les logements des portes outils ou de la tête amovible . In summary, the new method of cleaning a cylindrical protective mask of an upper side of the crankcase during the thermal spraying of the engine cylinder barrels, is implemented with a rotary apparatus consisting of a door body tool, with or without a detachable head, which has housings for inserting hole tools through their center, or tool cartridges with a hole in their center. These tools may be cutting inserts, brushes, or a combination of both. The tool holders may or may not have a removable tool holder head. The tools are screwed directly in their housing on the tool holders or on the removable head, or they are mounted in cartridges, themselves screwed into the housing of the tool holder or the removable head.
L'appareil opère simultanément le nettoyage du plan d'appui la du masque sur la face supérieure du carter-cylindres, et du bord intérieur du masque cylindrique en appui sur le carter- cylindre. Il assure également le nettoyage de la gouttière circulaire généralement ménagée dans la masse du masque à proximité de son bord intérieur.  The apparatus simultaneously operates the cleaning of the support plane of the mask on the upper face of the crankcase, and the inner edge of the cylindrical mask resting on the crankcase. It also ensures the cleaning of the circular gutter generally formed in the mass of the mask near its inner edge.
Les plaquettes ont par exemple des arêtes de coupe en carbure, en céramique ou en CBN (Nitrure de bore cubique) , avec des angles de permettant de couper les différentes matières de revêtement projetées dans les fûts de cylindres. Les plaquettes sont amovibles, et de préférence réversibles pour augmenter leur durée de vie. Les brosses sont également amovibles. Elles peuvent être en nylon, en acier ou en matériaux composites.  The platelets have, for example, cutting edges of carbide, ceramic or CBN (cubic boron nitride), with angles to cut the various coating materials projected in the barrels of cylinders. The pads are removable, and preferably reversible to increase their life. The brushes are also removable. They can be made of nylon, steel or composite materials.
La solution de référence, est un appareil de nettoyage à trois plaquettes. Toutefois, conformément à la description non limitative ci-dessus, l'invention couvre d'autres modes de réalisation et leurs variantes, notamment ceux de la liste suivante :  The reference solution is a three-bladed cleaning device.
