La figure ) représente une vue schématique en perspective d'un chariot d'usinage de dispositif selon
L'invention. The figure) represents a schematic perspective view of a device machining carriage according to
The invention.
La figure 3 représente schématiquement une vue agrandie du chariot d'usinage de la figure 2 en position d'usinage sur le bâti de la figure 1. FIG. 3 schematically represents an enlarged view of the machining carriage of FIG. 2 in the machining position on the frame of FIG. 1.
En référence à la figure 1, un dispositif selon l'invention comporte un bati présentant une forme générale en U matérialisée par exemple par un alignement de plusieurs supports i, par exemple de six supports 1. With reference to FIG. 1, a device according to the invention comprises a frame having a general U-shape materialized for example by an alignment of several supports i, for example of six supports 1.
Les supports 1, de préférence tous identiques, sont avantageusement fabriqués en bois lamel lé-colle, et peuvent présenter dans ce cas une norme de chaise renversée, dont les quatre montants 2 presentent des plans de collage sensiblement verticaux et ìlassise 3 des plans de collage sensiblement horizontaux. The supports 1, preferably all identical, are advantageously made of laminated wood, and may in this case have an inverted chair standard, the four uprights 2 of which have substantially vertical gluing planes and use 3 gluing planes substantially horizontal.
A l'extrémité supérieure des montants 2, on fixe deux tables de réception 4 s'étendant longitudinalement pour recevoir deux poutres 5 destinées à être rainurées pour devenir les membrures d'une poutre composite. At the upper end of the uprights 2, two reception tables 4 extending longitudinally are fixed to receive two beams 5 intended to be grooved to become the members of a composite beam.
Chaque poutre 5 est maintenue fermement dans l'-équerre de ia table de fixation 4 correspondante par des organes presseurs verticaux 6 et des organes presseurs horizontaux 7. Each beam 5 is held firmly in the square of the corresponding fixing table 4 by vertical pressing members 6 and horizontal pressing members 7.
Les organes presseurs 6 sont des vérins pneumatiques montés sur des équerres 6a solidaires d'une table 4, de manière à exercer une pression verticale sur la poutre 5, tandis que les organes presseurs 7 sont des vérins pneumatiques mùnis c-nacun d'un bras pivotant autour de la tige Jlorizontale au vérin 7 dans le sens de la flèche
P de maniere a faciliter le montage et le démontage rapides des poutres 5 sans interférer avec le parcours du chariot réalisant la ligne de rainurage Sa représentée en traits pointillés.The pressing members 6 are pneumatic jacks mounted on brackets 6a integral with a table 4, so as to exert vertical pressure on the beam 5, while the pressing members 7 are pneumatic jacks with a cn-arm pivoting around the Jlorizontal rod to the cylinder 7 in the direction of the arrow
P so as to facilitate rapid assembly and disassembly of the beams 5 without interfering with the path of the carriage making the grooving line Sa shown in dotted lines.
Le montants 2 du bâti supportent également deux axes de guidage 8 s'étendant parallèlement aux tables 4 et fixés sur des surfaces d'appui 2a,4a usinées respectivement dans des montants 2 et la table d'appui 4 qu'ils supportent au moyen de supports d'axe 8a correspondants. The uprights 2 of the frame also support two guide pins 8 extending parallel to the tables 4 and fixed on support surfaces 2a, 4a machined respectively in uprights 2 and the support table 4 which they support by means of corresponding axis supports 8a.
La table ou assise 3 présente un logement central 3a apte à recevoir centralement une poutre 9. The table or seat 3 has a central housing 3a capable of receiving a beam 9 centrally.
La poutre 9 sensiblement horizontale, réalisée par exemple en bois lamellé-collé avec des plans de collage orienté sensiblement verticalement, porte une crémaillère horizontale 10 et deux gabarits il présentant une forme en ligne brisée dont les segments successifs orientés en sens inverse l'un de l'autre font un petit angle avec l'horizontale de la crémaillère. The substantially horizontal beam 9, made for example of glued laminated wood with bonding planes oriented substantially vertically, carries a horizontal rack 10 and two jigs it having a broken line shape whose successive segments oriented in opposite direction one of the other make a small angle with the horizontal of the rack.
Dans ce cas, les gabarits il en ligne brisée sont avantageusement réalisés par assemblage de cornières soudées l'une a l'autre, ces assemblages étant ensuite fixés par vis li sur les flancs latéraux 9a,9b de la poutre 9. In this case, the templates il in a broken line are advantageously produced by assembling angles welded to one another, these assemblies then being fixed by screws li on the lateral flanks 9a, 9b of the beam 9.
L'invention permet ainsi de remplacer rapidement une première poutre Y, portant à la fois un moyen d'entraînement en translation 10 du genre crémaillère et des moyens de guidage d'outil tels que des gabarits il et correspondant à un premier modèle de poutre composite à réaliser par une deuxième poutre 9 correspondant à un deuxième modèle de poutre composite. The invention thus makes it possible to quickly replace a first beam Y, carrying both a drive means in translation 10 of the rack type and tool guide means such as templates it and corresponding to a first model of composite beam to be produced by a second beam 9 corresponding to a second model of composite beam.
En référence à la figure 2, un chariot 13 d'usinage comporte un bloc de translation 14 et un bloc d'usinage 15. With reference to FIG. 2, a carriage 13 for machining comprises a translation block 14 and a machining block 15.
Le bloc de translation 14 comporte deux paliers 16a,16b du type douille à billes fendue, aptes à être guidés en translation par les axes 8 du bâti. L'entraînement du bloc de translation 14 résulte de l'engrènement d'une roue dentée 17 entraînée par un motoréducteur 18 avec la crémaillère 10.The translation block 14 comprises two bearings 16a, 16b of the split ball bushing type, capable of being guided in translation by the axes 8 of the frame. The drive of the translation block 14 results from the engagement of a toothed wheel 17 driven by a geared motor 18 with the rack 10.
Le motoréducteur 18 et la roue dentée 17 solidaires du bloc de translation 14 sont choisis de manière à ce que le déplacement en translation horizontale dans un sens ou dans 1 autre du bloc i4 s'effectue à une vitesse d'avancement inférieure à dix mètres par minute. The geared motor 18 and the toothed wheel 17 integral with the translation block 14 are chosen so that the displacement in horizontal translation in one direction or in another of the block i4 takes place at a forward speed of less than ten meters by minute.
Avantageusement, le motoréducteur est alimenté électriquement au moyen d'un convertisseur de fréquence de manière à régler à volonté la vitesse de translation à une valeur choisie de préférence entre un et cinq mètres par minute.Advantageously, the gearmotor is electrically powered by means of a frequency converter so as to adjust the translation speed at will to a value preferably chosen between one and five meters per minute.
Le bloc d'usinage 15 comporte deux axes parallèles 19a,19b montes a coulissement vertical dans des douilles à billes 20 ou paliers de translation verticale analogues solidaires du bloc de translation 14. The machining block 15 comprises two parallel axes 19a, 19b mounted for vertical sliding in ball bushings 20 or similar vertical translation bearings integral with the translation block 14.
Les extrémités inférieures des axes 19a,19b sont montées sur des roulettes de guidage ou galets 21 roulant sur les rails ou gabarits 11, tandis que les extrémités supérieures des axes 19a,19b portent un support 22 auquel est assujetti un moteur 3 à deux arbres de sortie tournant des vitesses de l'ordre de 20 000 tours par minute, de manière à usiner simultanément au moyen de fraises 24 à fond plat des rainures Sa dans des membrures 5 disposées de part et d'autre du chariot 13. The lower ends of the axes 19a, 19b are mounted on guide rollers or rollers 21 rolling on the rails or jigs 11, while the upper ends of the axes 19a, 19b carry a support 22 to which a motor 3 has two shafts of rotating output speeds of the order of 20,000 revolutions per minute, so as to machine simultaneously by means of cutters 24 with flat bottom grooves Sa in members 5 arranged on either side of the carriage 13.
Avantageusement, selon l'invention, on prévoit de réaliser le dispositif comprenant le bâti et le chariot symétriquement par rapport au plan (ou à la surface dans le cas d'une poutre composite courbe) vertical passant par la ligne neutre de la poutre composite à réaliser : dans ce cas, ce plan vertical passant par la crémaillère 10 est équidistant de l'extrémité des fraises 24 qui se déplacent coaxialement et norizontalement selon le mouvement imposé par les roulettes ou galets 21 roulant sur des gabarits il symétriques par rapport à ce plan vertical ou à tout le moins imposant toujours un déplacement vertical identique aux fraises 24). Advantageously, according to the invention, provision is made to produce the device comprising the frame and the carriage symmetrically with respect to the vertical plane (or to the surface in the case of a curved composite beam) passing through the neutral line of the composite beam to achieve: in this case, this vertical plane passing through the rack 10 is equidistant from the end of the cutters 24 which move coaxially and norizontalally according to the movement imposed by the rollers or rollers 21 rolling on jigs it symmetrical with respect to this plane vertical or at the very least always requiring a vertical displacement identical to the cutters 24).
En référence à la figure 3, selon l'invention, on met en place une poutre 5 sur chaque table 4 en calant éventuellement la poutre 5 à la hauteur appropriée, et on assujettit la poutre D sur son chant à la table 4 en faisant pivoter les organes presseurs horizontaux dans le sens de la flèche P puis en appliquant des pressions de maintien horizontale et verticale respectivement dans le sens des flèches H et V. La longueur des poutres 5 est variable ; ltessentiel étant que les poutres soient disposées longitudinalement selon l'axe de la machine de manière d ce que les rainures en zig-zag soient symétriques dans le sens de leur longueur et présentent des extrémités identiques. With reference to FIG. 3, according to the invention, a beam 5 is put in place on each table 4, possibly wedging the beam 5 at the appropriate height, and the beam D is secured on its edge to the table 4 by rotating the horizontal pressing members in the direction of the arrow P then by applying horizontal and vertical holding pressures respectively in the direction of the arrows H and V. The length of the beams 5 is variable; ltessentiel being that the beams are arranged longitudinally along the axis of the machine so that the zig-zag grooves are symmetrical in the direction of their length and have identical ends.
Cette fixation symétrique sur les tables 4 étant réalisée, on met en marche le moteur d'usinage 23 et on commande le déplacement du chariot 13 en agissant sur le moteur 18 à vitesse variable qui entraîne la roue dentée 17 engrenant et coopérant avec la crémaillère 10. This symmetrical fixing on the tables 4 having been carried out, the machining motor 23 is started and the movement of the carriage 13 is controlled by acting on the motor 18 at variable speed which drives the toothed wheel 17 meshing and cooperating with the rack 10 .
Le guidage en translation du chariot 13 est parfaitement défini par le plan horizontal passant par les axes 8 du bâti, sur lesquels coulissent les paliers a billes 16a,16b du chariot 13. The guiding in translation of the carriage 13 is perfectly defined by the horizontal plane passing through the axes 8 of the frame, on which the ball bearings 16a, 16b of the carriage 13 slide.
Dans le mouvement de translation horizontale du chariot lj, le moteur 23 et les fraises 24 ou outils analogues se déplacent selon une oscillation verticale imposée par le roulement des galets 21 sur les gabarits 11 l'invention permet ainsi d'usiner des rainures Sa en ligne brisée qui se correspondent exactement face à face dans les membrures 5. In the horizontal translational movement of the carriage lj, the motor 23 and the milling cutters 24 or similar tools move in a vertical oscillation imposed by the rolling of the rollers 21 on the jigs 11 the invention thus makes it possible to machine grooves Sa in line broken which correspond exactly face to face in the members 5.
L'invention permet ainsi de créer des logements Sa pour une âme en contreplaqué exactement symétriques dans les membrures 5. The invention thus makes it possible to create housings Sa for an exactly symmetrical plywood core in the members 5.
Après dépôt d'un joint de colle dans les logements Sa, il suffit de mettre en place l'âme en contreplaqué et de mettre les membrures 5 de la poutre composite en compression sur l'âme pendant le temps de prise pour obtenir une poutre composite prête à l'emploi. After depositing an adhesive joint in the housings Sa, it suffices to put the plywood core in place and to put the members 5 of the composite beam in compression on the core during the setting time to obtain a composite beam ready to use.
L'invention décrite en référence à un mode de réalisation particulier n'y est nullement limitée, mais englobe au contraire toute modification de forme et toue variante de réalisation, dans lesquelles un chariot portant des moyens d'usinage, symétriques par rapport à une surface, et déplaçables dans un premier sens selon un parcours imposé par le roulement d'au moins un galet sur un gabarit, est entraîné en translation selon une courbe contenue dans la surface de symétrie des moyens d'usinage précités. The invention described with reference to a particular embodiment is in no way limited thereto, but on the contrary includes any modification of shape and any variant embodiment, in which a carriage carrying machining means, symmetrical with respect to a surface , and movable in a first direction along a path imposed by the rolling of at least one roller on a template, is driven in translation along a curve contained in the surface of symmetry of the aforementioned machining means.
