La Figure 3 représente schématiquement une vue en coupe partielle du dispositif selon l'invention selon la ligne III-III de la figure 1. FIG. 3 schematically represents a view in partial section of the device according to the invention according to line III-III of FIG. 1.
La Figure 4 représente schématiquement une vue en perspective partielle d'un dispositif selon l'invention. Figure 4 schematically shows a partial perspective view of a device according to the invention.
En référence aux figures 1 à 3, un dispositif selon l'invention comporte un portique 1 enjambeur déplaçable sur deux rails parallèles 2 et 3 au moyen de moteurs 4 et 5 synchronisés de manière a déplacer le portique dans le sens de la flèche R en restant perpendiculaire la direction des rails 2 et 3. Referring to Figures 1 to 3, a device according to the invention comprises a gantry 1 straddle movable on two parallel rails 2 and 3 by means of motors 4 and 5 synchronized so as to move the gantry in the direction of the arrow R while remaining perpendicular to the direction of rails 2 and 3.
Le portique 1 comporte une jambe d'appui 6 de hauteur correspondant a la différence de hauteur des murettes longitudinales 2a, 3a de soutien des rails 2, 3 et une poutre transversale 7 comportant un évidement central 7c de manière a constituer deux poutres de support 7a, 7b solidaires entre elles et parallèles l'une à l'autre. The gantry 1 comprises a support leg 6 of height corresponding to the difference in height of the longitudinal walls 2a, 3a for supporting the rails 2, 3 and a transverse beam 7 comprising a central recess 7c so as to constitute two support beams 7a , 7b integral with each other and parallel to each other.
Aux extrémités du portique 1, on fixe un dispositif 8 d'alimentation électrique de puissance contenu dans une armoire étanche correspondante et un dispositif 9 de commande numérique contenu dans une armoire correspondante et supportée par exemple par la jambe d'appui 6. At the ends of the gantry 1, a device 8 for supplying electrical power contained in a corresponding sealed cabinet and a digital control device 9 contained in a corresponding cabinet and supported for example by the support leg 6 are fixed.
Selon l'invention, le dispositif comporte un moyen 10 d'usinage (notamment de fraisage ou de polissage) apte a se déplacer le long de la poutre 7 en passant par l'évidement central 7c. According to the invention, the device comprises a means 10 for machining (in particular for milling or polishing) capable of moving along the beam 7 passing through the central recess 7c.
De préférence, le déplacement du moyen 10 d'usinage est commandé par un premier moyen de motorisation électrique 11, de préférence contrôlé par commande numerique. Preferably, the movement of the machining means 10 is controlled by a first electric motor means 11, preferably controlled by numerical control.
Dans son déplacement, le moyen 10 d'usinage vient au contact des faces latérales d'une pièce a fraiser ou à polir telle qu'un escalier E (représenté en traits mixtes) disposé de manière usuelle sous le portique enjambeur 1. In its movement, the machining means 10 comes into contact with the lateral faces of a part to be milled or polished such as a staircase E (shown in phantom) arranged in the usual manner under the straddle gantry 1.
Selon l'invention, le moyen 10 d'usinage présente une configuration en M dont la jambe médiane 12 passe a travers l'espace 7c, de manière a fixer un outil central, par exemple une meule 12b entra#née en rotation par un moteur 12c, par l'intermédiaire d'un arbre porte-outil 12a montant et descendant dans le sens de la flèche T sous l'action de deux vérins hydrauliques. According to the invention, the machining means 10 has a configuration in M, the middle leg 12 of which passes through the space 7c, so as to fix a central tool, for example a grinding wheel 12b driven in rotation by a motor. 12c, by means of a tool-holder shaft 12a rising and falling in the direction of arrow T under the action of two hydraulic cylinders.
Les deux jambes latérales 13 et 14 du M reçoivent a coulissements U, Y parallèles au déplacement correspondant a la flèche T, des supports respectifs 13a, 14a se déplaçant sous l'action de moteurs 15, 16 entraînant des vis a billes leva, 16a ou organes de translation analogues par exemple du type crémaillères. The two lateral legs 13 and 14 of the M receive, U, Y sliding parallel to the displacement corresponding to the arrow T, respective supports 13a, 14a moving under the action of motors 15, 16 driving leva ball screws, 16a or analogous translation members, for example of the rack type.
Dans le mouvement de translation suivant la flèche
S, le moyen 10 en forme de M chevauche les deux poutres 7a et 7b en étant guide sur des axes rigides 17a, 17b coopérant avec des bottiers solidaires de la forme 10 en M et recevant des douilles à billes fendues de type connu en soi.In the translational movement following the arrow
S, the M-shaped means 10 overlaps the two beams 7a and 7b while being guided on rigid axes 17a, 17b cooperating with shoemakers integral with the form 10 in M and receiving split ball bushings of a type known per se.
A l'extrémité inférieure des supports 13a, 14a, sont montées a pivotement autour d'axes horizontaux deux têtes porte-outils 18 et 19 réglables en inclinaison manuellement par un système vis-écrou ou au moyen d'un vérin 20 commande par un distributeur. At the lower end of the supports 13a, 14a, are pivotally mounted around horizontal axes two tool-holder heads 18 and 19 adjustable in inclination manually by a screw-nut system or by means of a jack 20 controlled by a distributor .
Le vérin 20 est, par exemple, un vérin hydraulique à double effet, mais il peut également être un vérin à commande électrique du type vis à billes recirculantes. The jack 20 is, for example, a double-acting hydraulic jack, but it can also be an electrically controlled jack of the recirculating ball screw type.
Au moins une tête porte-outil 18 ou 19 comporte un moyen d'appui en pression 21 ou 22, par exemple du type vérin hydraulique, de manière à polir les marches d'un escalier 23 en pierre ou en granit reconstitue, ou en marbre ou en matériaux reconstitués etlou réfractaires analogues en appliquant l'outil de polissage correspondant 18a ou 19a ur la pièce à polir avec une pression prédéterminée. At least one tool-carrying head 18 or 19 comprises a pressure support means 21 or 22, for example of the hydraulic jack type, so as to polish the steps of a staircase 23 in stone or in reconstituted granite, or in marble or in reconstituted and / or similar refractory materials by applying the corresponding polishing tool 18a or 19a to the part to be polished with a predetermined pressure.
Au moins une tête 18 ou 19 est montée sur son support 13a ou 14a par l'intermédiaire d'un moyen d'orientation en rotation 24 permettant un tour complet de la tête 19 sur elle-meme ou une rotation de la tête 19 éventuellement limitée par des butées de rotation non représentées. At least one head 18 or 19 is mounted on its support 13a or 14a by means of a rotating orientation means 24 allowing a complete turn of the head 19 on itself or a rotation of the head 19 possibly limited by rotational stops not shown.
Des balais antiprojections et antisalissures représentés en traits pointillés sont disposes autour des outils 18a, 12b, 19a de manière connue pour éviter toute projection sur le personnel et tout encrassement des outils voisins. Anti-spray and anti-fouling brushes represented in dotted lines are arranged around the tools 18a, 12b, 19a in a known manner to avoid any projection on the personnel and any fouling of neighboring tools.
Comme on le voit sur les figures 3 et 4, l'arbre porte-outil 12a porte une meule 12b animée d'un mouvement de montée et descente pour polir les nez 23a de marche d'un escalier 23, tandis que la tête porte-outil 18 est orientée par réglage manuel selon un angle prédéterminé à plus ou moins cinq degrés d'angle sexagésimaux près, correspondant au fraisage et au polissage des marches 23b au moyen d'une meule 18a sous une pression d'appui éventuellement fournie par le moyen 21, et tandis que la tête porte-outil 19 est orientée selon un angle A au moyen du vérin hydraulique 20 de manière à polir les contre-marches 23c au moyen de la meule 19a éventuellement sous une pression d'appui fournie par le moyen 22. As can be seen in FIGS. 3 and 4, the tool-holder shaft 12a carries a grinding wheel 12b driven in an up and down movement to polish the stair noses 23a of a staircase 23, while the head holder tool 18 is oriented by manual adjustment at a predetermined angle to within plus or minus five degrees of sexagesimal angle, corresponding to the milling and polishing of the steps 23b by means of a grinding wheel 18a under a pressing pressure possibly supplied by the means 21, and while the tool-holder head 19 is oriented at an angle A by means of the hydraulic cylinder 20 so as to polish the counter-steps 23c by means of the grinding wheel 19a possibly under a pressing pressure supplied by the means 22 .
Grâce au moyen d'orientation en rotation 24, la tête porte-outil 19 peut être tournée de plus ou moins 900 de manière à polir également les faces latérales de l'escalier 20. Thanks to the rotating orientation means 24, the tool-carrying head 19 can be turned more or less 900 so as to also polish the lateral faces of the staircase 20.
Grâce à l'invention, le polissage et le fraisage complets de toute la surface extérieure d'une pierre de forme quelconque ou d'un élément moule du type escalier en béton est ainsi effectué sans aucune manutention ou changement de place et sans aucune intervention de l'opérateur à l'intérieur de l'espace de travail. Thanks to the invention, the complete polishing and milling of the entire external surface of a stone of any shape or of a mold element of the concrete staircase type is thus carried out without any handling or changing of place and without any intervention of the operator inside the workspace.
L'invention procure ainsi simultanément une augmentation de productivité et une amélioration des conditions de sécurité du personnel opérateur.The invention thus simultaneously provides an increase in productivity and an improvement in the safety conditions of the operating personnel.
Selon un mode de réalisation préféré de l'invention, l'armoire de commande numérique 9 comporte un écran de dialogue avec l'opérateur, permettant au moyen d'un programme de type conversationnel de positionner la pièce à fraiser et à polir selon une position de référence géométrique de départ, et de fournir à la commande numérique les informations géométriques nécessaires à l'obtention de la pièce finie. According to a preferred embodiment of the invention, the digital control cabinet 9 includes a screen for dialogue with the operator, allowing by means of a conversational type program to position the part to be milled and polished according to a position starting geometrical reference point, and supplying the numerical control with the geometrical information necessary for obtaining the finished part.
Un tel dispositif de commande numérique est, à titre d'exemple, un dispositif vendu sous la dénomination "NUM 750" par la Société de droit français NUM. Such a digital control device is, for example, a device sold under the name "NUM 750" by the French company NUM.
Dans un mode de réalisation avantageux du dispositif destiné par exemple à l'usinage et au polissage d'escaliers, la commande numérique pilote de maniere indépendante et préférentiellement selon des coordonnées trirectangulaires les cinq axes de translation correspondant aux déplacements repérés par les flèches R,
S, T, U, V.In an advantageous embodiment of the device intended for example for the machining and polishing of stairs, the digital control controls independently and preferably according to trirectangular coordinates the five axes of translation corresponding to the displacements indicated by the arrows R,
S, T, U, V.
Le réglage de l'inclinaison de la tête porte-outil 18 est par exemple manuel, tandis que l'inclinaison de la tête 19 est automatique selon une position "tout ou rien" sous l'action du vérin hydraulique 20 piloté par un distributeur ou moyen analogue non représenté. The inclination of the tool-holder head 18 is for example manual, while the inclination of the head 19 is automatic in an "all or nothing" position under the action of the hydraulic cylinder 20 controlled by a distributor or analogous means not shown.
La rotation de la tête porte-outil 19 autour de son axe à l'aide du moyen d'entraînement en rotation 24 de type connu est plus précise que les inclinaisons précitées, et ce positionnement angulaire précis est maintenu grâce à un frein hydraulique au moyen de bridage hydraulique analogue du type blocage réversible à cône expansible sur cylindre. The rotation of the tool-holder head 19 about its axis using the known rotary drive means 24 is more precise than the aforementioned inclinations, and this precise angular positioning is maintained by means of a hydraulic brake by means of similar hydraulic clamping of the reversible blocking type with expandable cone on cylinder.
De préférence, pour le fraisage, l'outil travaille en profondeur de passe, tandis que, pour le polissage, l'outil est appliqué sur la pierre ou le béton avec une pression d'appui comprise entre 20 bar et 100 bar et dépendant du type de matériau usiné à titre d'exemple, pour un escalier en béton, la pression d'appui est inférieur ou égale à 40 bar. Preferably, for milling, the tool works in depth of cut, while, for polishing, the tool is applied to stone or concrete with a contact pressure between 20 bar and 100 bar and depending on the type of material machined as an example, for a concrete staircase, the contact pressure is less than or equal to 40 bar.
Les porte-outils 12a, 18, 19 sont de préférence des broches entraînéeS é 1 e c t r i q u e m e n t en rotation a vitesse variable par un variateur à commande électronique pilote par la commande numérique. The tool holders 12a, 18, 19 are preferably spindles which are driven in rotation at variable speed by a variator with electronic control piloted by digital control.
Selon l'invention, pour usiner un ensemble comportant des plans raccordés entre eux par exemple du type escalier, le dispositif selon l'invention peut ne comporter qu'un variateur de vitesse unique, qui entraîne à tour de rôle une seule broche 12a ou 18 ou 19 à la fois. According to the invention, in order to machine an assembly comprising planes connected to each other, for example of the staircase type, the device according to the invention may comprise only a single variable speed drive, which in turn drives a single spindle 12a or 18 or 19 at a time.
Selon l'invention, un procédé pour usiner les marches d'un escalier ou ensemble analogue comporte, par exemple, les étapes suivantes
a) positionner l'un par rapport à l'autre le dispositif et l'escalier à usiner conformément au plan d'exécution,
b) usiner en se déplaçant dans un premier sens de translation du portique (correspondant par exemple à l'axe

c) retirer l'outil actif 18a pour l'éloigner de l'escalier par translation selon son axe correspondant V, effectuer un déplacement automatique calculé par le programme de commande numérique en fonction du plan d'exécution selon un deuxième sens de déplacement du portique (correspondant dans ce cas à l'axe de translation
R),
d) usiner en se déplaçant dans ledit premier sens de translation du portique au moyen du même outil 18a ou d'un autre outil 12b ou 19a,
e) recommencer S'étape b) jusqu'à usinage complet de l'escalier.According to the invention, a method for machining the steps of a staircase or the like comprises, for example, the following steps
a) position the device and the staircase to be machined in relation to the other in accordance with the execution plan,
b) machining by moving in a first direction of translation of the gantry (corresponding for example to the axis
S), for example milling or polishing the staircase by means of a first tool 18a, while the other tools 12a and 19 are distant from the staircase,
c) remove the active tool 18a to move it away from the staircase by translation along its corresponding axis V, carry out an automatic displacement calculated by the digital control program as a function of the execution plan according to a second direction of movement of the gantry (corresponding in this case to the axis of translation
R),
d) machining by moving in said first direction of translation of the gantry using the same tool 18a or another tool 12b or 19a,
e) start again Step b) until the staircase is completely machined.
Selon une première variante du procédé selon l'inventions on prévoit des étapes supplémentaires suivantes correspondants au fraisage des faces latérales
tourner l'outil 19a d'un angle désiré correspondant à l'application de la meule 19a sur une face latérale désirée de l'escalier,
usiner en se déplaçant dans ledit deuxième sens la face latérale c o n c e r n é e. According to a first variant of the method according to the invention, the following additional steps are provided corresponding to the milling of the lateral faces

actuate the means for hydraulically supporting the tool 18a, 12b or 19a on the part to be polished,
machining by moving along a translation axis U or R or S or T or V while keeping the contact pressure substantially constant.
L'invention décrite en référence à des modes de réalisation particuliers nry est pas limitée, mais englobe au contraire tout modification de forme et toute variante de réalisation dans le cadre et l'esprit de l'invention. The invention described with reference to particular embodiments nry is not limited, but on the contrary encompasses any modification of form and any variant embodiment within the scope and spirit of the invention.
