Description

Machine à fabriquer des pièces en bois, notamment des rais pour les roues de voitures La présente invention est relative à une machine à fabriquer des pièces en bois, no lament des rais pour les roues de voitures, suivant la revenclication du brevet principal. Machine for making wooden parts, in particular spokes for car wheels The present invention relates to a machine for manufacturing wooden parts, not lament spokes for car wheels, according to the claim of the main patent.

Dans cette machine, un levier à contre poids qui provoque par son cliquet le mou vement angulaire de la pièce type et de la pièce à usiner, se termine par une fourche munie de deux vis de butée réglables, ces vis portant sur une rondelle fixée concentriquement sur une barre coulissante, laquelle s'ap- puie sur des galets coniques facilitant le deplacement de cette barre. In this machine, a lever with counterweight which causes by its pawl the angular movement of the standard part and of the part to be machined, ends in a fork provided with two adjustable stop screws, these screws bearing on a washer fixed concentrically on a sliding bar, which rests on conical rollers facilitating the movement of this bar.

Le dessin ci-annexe, donne à titre d'exemple, montre une forme d'execution de la machine. The attached drawing, given by way of example, shows one form of execution of the machine.

Fig. 1 is a side view of the machine; Fig. 2 is a plan view; Fig. 3 shows the machine seen from the front; Fig. 4 is a detail view on a larger scale of the clispositif imparting an angular movement to the parts mounted on the machine.

1 désigne le bâti de la machine, supportant un arbre porte-outil 2 qui est pourvu à l'une de ses extrémités d'une poulie d'en- tramement 3, tandis que son autre extrémité reçoit un outiL 4, qui a la forme d'une fraise convexe, de rayon déterminé et qui est dé- gage de maniere a obtenir une coupe dans le sens de rotation. 1 denotes the frame of the machine, supporting a tool-carrying shaft 2 which is provided at one of its ends with a driving pulley 3, while its other end receives a tool 4, which has the shape of a convex milling cutter, of determined radius and which is disengaged so as to obtain a cut in the direction of rotation.

Une barre d'acier 5 en forme d'U, fixee au bâti 1, recoit à chacune de ses extrémités des équerres 6 et 7, dans-lesquelles peut coulisser une barre en acier 8 reposant sur des galets coniques 7a (fig. 4) qui facilitent le déplacement de la barre. Sur cette barre sont montes, d'une part, un support fixe 9 et, d'autre part, un support mobile 10 pouvant être immobilise par une vis 14 qui pe nitre dans une rainure de la barre 8. A steel bar 5 in the shape of a U, fixed to the frame 1, receives at each of its ends brackets 6 and 7, in which can slide a steel bar 8 resting on conical rollers 7a (fig. 4) which facilitate the movement of the bar. On this bar are mounted, on the one hand, a fixed support 9 and, on the other hand, a mobile support 10 which can be immobilized by a screw 14 which pe niters in a groove of the bar 8.

Le support 10 est pourvu de contre-pointes réglables 15,16, tandis que le support 9 porte des griffes d'entraînement 17 et 18 formées sur les axes des roues dentées 19 et 20 qui sont en prise avec une roue dentée intermédiaire 21, de même diamètre et montee librement sur le support 9, concentriquement à la barre 8. Les axes de ces roues traversent le support 9. The support 10 is provided with adjustable tailstocks 15,16, while the support 9 carries drive claws 17 and 18 formed on the axes of the toothed wheels 19 and 20 which are engaged with an intermediate toothed wheel 21, same diameter and mounted freely on support 9, concentrically to bar 8. The axles of these wheels pass through support 9.

22 désigne un levier oscillait monte librement sur l'axe de la roue dentée 20, par exemple, et pourvu à l'une de ses extremi- tes d'un contrepoids 22. Sur ce levicr 22 est dispose un cliquet à ressort 23 maintenu en prise avec la roue dent-zée 20. Le levier 22 est en outre termine par une sorte de four clic dont les branches portent des vis de bu tee 24, 25 qui peuvent porter t. our a tour sur une rondelle 26 fixée sur la barre 8, ce qui permet de limiter les deplacements du levier 22. 22 denotes an oscillating lever mounted freely on the axis of the toothed wheel 20, for example, and provided at one of its ends with a counterweight 22. On this lever 22 is arranged a spring pawl 23 held in place. taken with the tooth-zee wheel 20. The lever 22 is also terminated by a sort of click oven whose branches carry tee bu screws 24, 25 which can carry t. our turn on a washer 26 fixed on the bar 8, which makes it possible to limit the displacements of the lever 22.

Le bâti 1 est pourvu d'un butoir 27 (fig. The frame 1 is provided with a stopper 27 (fig.

2) sur lequel peut venir porter le contrepoids 92fa du levier 22. 2) on which can come to bear the counterweight 92fa of the lever 22.

Les supports 9 et 10 sont pourvus chacun d'une poignée de manoeuvre 31 et 32. The supports 9 and 10 are each provided with an operating handle 31 and 32.

11 désigne le rais-type pris entre la contre-pointe 15 et la griffe 17. Ce rais repose sur une molette de réglage 33 disposée dans un support réglable 33a monte sur la barre 5. 11 designates the spoke-type taken between the tailstock 15 and the claw 17. This spoke rests on an adjustment wheel 33 arranged in an adjustable support 33a mounted on the bar 5.

Le rais à usiner 12 est simplement ebauche à la scie et pris entre la contre-pointe 16 et la griffe 18 parallèlement au rais type 11. The spoke to be machined 12 is simply roughed out with a saw and taken between the tailstock 16 and the claw 18 parallel to the spoke type 11.

Le fonctionnement de cette machine est le suivant. The operation of this machine is as follows.

Le rais-type et le rais à usiner ayant été convenablements mont#s et centr#s horizon- talement entre les griffes et les contre-pointes des supports 9 et 10, on règle la hauteur de la molette 33 suivant le diamètre que l'on désire donner au rais à fabriquer. The standard spokes and the spokes to be machined having been suitably mounted and centered horizontally between the claws and the tailstocks of the supports 9 and 10, the height of the wheel 33 is adjusted according to the diameter that the we want to give the spokes to be made.

On amène ensuite les supports 9 et 10 vers la droite, en saisissant les poignées de manoeuvre 31 et 32, de maniere que la fraise 4 vienne à l'extrémité de gauche de la pièce 12. The supports 9 and 10 are then brought to the right, by grasping the operating handles 31 and 32, so that the cutter 4 comes to the left end of the part 12.

L'arbre porte-outil 2 ayant 6t6 mis en marche, on appuie legerement sur les poignees 31 et 32 de manière à faire porter eonstamment le rais type 11 sur la molette '33 et à guider ainsi le rais à usiner sous la fraise 4. En meme temps qu'on appuie sur' les poignees de manceuvre, on pousse lentement la barre 8 et ses supports vers la gauche. jusqu'au bout, ce mouvement étant limite par l'équerre 6. Cette première passe effectu#e, on releve vivement les poignées ds ina. ncfuvre 31 et. 32, de leçon à faire porte le levier 22 sur le butoir 27. Ce levier ei baseulant fait, par I'interm#diaire de son (li quet à ressort ? 3, avancer la roue 21 et pa] suite les roues l9 et 9 (!, d'une dent par exom ple. Les rais ayant effectu# tous deux l@ même mouvement (bulaire, on ramene ra pidement] les supports vers la droite jusqu'au bout. Puis on appuie à nouveau sur les poi de de man#uvre et on pousse lentemenl vers la gauche. On effectue ainsi une se conde passe. The tool-holder shaft 2 having 6t6 started, one presses lightly on the handles 31 and 32 so as to bring the spoke type 11 constantly on the wheel '33 and thus to guide the spoke to be machined under the cutter 4. At the same time as the maneuvering handles are pressed, the bar 8 and its supports are slowly pushed to the left. until the end, this movement being limited by the square 6. This first pass effected, we quickly raise the handles ds ina. ncfuvre 31 and. 32, of lesson to be made carries the lever 22 on the stopper 27. This lever ei baseulant, by I'intermediary of its (li quet with spring? 3, to advance the wheel 21 and pa] following the wheels 19 and 9 (!, of a tooth for example. The spokes having both made the same movement (bular, we quickly bring back the supports to the right until the end. Then we press again on the weights of maneuver and push slowly to the left, thus performing a second pass.

Ces op#rations se r#p#tent jusqu'# ce qu@ le rais à usiner ait fait un tour complet ex soll completement termine. These operations are repeated until the spoke to be machined has made a complete turn, ex soll completely finished.

On remarquera que le pliquet 23 s'armf automatiquement chaque fois que le leviei 22 Hbere du butoir 27 bascule sous 1'effet #d@ son contrepoids 22. Los oselHations dp cc levier peuvent etre reglees au moyen des vis 24 et 25 qui portent sur la rondelle 26. On peut ainsi r#gler les d#placements du clique@ sur la roue dentée 90 et par suite, on peut faire varier l'amplitude du mouvement an glaire impnmp aux rais 11 et 12. It will be noted that the latch 23 armf automatically each time the lever 22 Hbere the stopper 27 switches under the effect # d @ its counterweight 22. Los oselHations dp cc lever can be adjusted by means of screws 24 and 25 which bear on the washer 26. It is thus possible to adjust the displacements of the clique@ on the toothed wheel 90 and as a result, the amplitude of the angular movement impnmp to the spokes 11 and 12 can be varied.

Les rais ainsi obtenus sont entierement finis. H n'y a plus qu'a leur donner un coup de racloir. The spokes thus obtained are entirely finite. All you have to do is give them a scrape.
