Description

Outillage pour la terminaison des tiges de remontoir avant leer montage dans la boite de montre Avant 1e montage des tiges de remontoir dans les boites de montres, an les met ä la longueur exacte, par exemple en les coupant ä 1'aide dune pince ou d'une cisaille dopt an connait diffdrents types, puis Fon visse la couronne de remontoir, sur 1'extremite ext6rieure ddjä filetee de la tige. Ces differentes opdrations de- mandent passablement d'habilete manuelle et de patience, donc beaucoup de temps pour une main- d'ceuvre coüteuse. Tools for terminating the winding stems before mounting them in the watch case Before mounting the winding stems in the watch cases, they are cut to the exact length, for example by cutting them using pliers or There are different types of shears fitted, then the winding crown is screwed onto the already threaded outer extremity of the stem. These various operations require considerable manual skill and patience, and therefore a lot of time for expensive labour.

L'on a ddjä tentd de mdcaniser des opdratidns, notamment en montant 1e mouvement muni de sa tige dans un support se d6plagant en regard d'abord dun dispositif d'usinage de cette tige et ensuite devant un mandrin dans lequel est pincee une couronne et qui prAente des moyens permettant de visser cette cou- ronne sur la tige ; ces machirres n'ont cependant jus- qu'ä pr6sent pas donn6 satisfaction car elles sont rela- tivement compliqudes et exigent un montage prdalable de la tige dans la montre. Attempts have already been made to mechanize operations, in particular by mounting the movement fitted with its stem in a support moving first opposite a device for machining this stem and then in front of a chuck in which a crown is clamped and which presents means making it possible to screw this crown onto the stem; however, these jaws have not until now given satisfaction because they are relatively complicated and require prior assembly of the stem in the watch.

D'autre part, an connait en mecamque generale diff6rents dispositifs permettant 1e vissage automatique d'un ecrou sur une tige filet6e ä 1'aide de machirres relativement complexes, mais 1'on n'a jamais utilisd et adaptd de fagon simple de tels dispositifs au vissage de couronnes de remontoir. On the other hand, one knows in general mechanics various devices allowing the automatic screwing of a nut on a threaded rod with the aid of relatively complex jaws, but such devices have never been used and adapted in a simple way. screwing winding crowns.

La prdsente Invention a precisement pour objet un outillage pour la terminaison des tiges de remontoir, avant leur montage dans la montre. Cet outillage est caracteris6 par une pince pour saisir ces tiges en les positionnant axialement ä 1'aide dune butde coop6rant avee la portee de la tige servant d'appui au pignon de remontoir, par un dispositif pour les couper ä leur lon- gueur exacte et pr6sentant ä cet effet une plaque d'ap- pui dispos6e ä une distance reglable dudit dispositif et contre laquelle vieret s'appuyer la pince, par un socle pr6sentant des emplacements dopt chacun est destin6 ä recevoir une couronne de remontoir disposde sens dessus dessous, dans 1e but que Fon puisse y chasser 1'extrdmite exterieure de la tige une fois coupde, par un dispositif pr6sentant des galets rotatifs devant les- quels peut se deplacer un coulisseau dann 1e but que Fon puisse engager entre celui-ci et les galets la tige chassde dans la couronne pour visser cette derniere. The subject of the present invention is precisely a tool for terminating the winding stems, before they are mounted in the watch. This tool is characterized by pliers for grasping these stems by positioning them axially using a butt cooperating with the bearing surface of the stem serving as a support for the winding pinion, by a device for cutting them to their exact length and presenting for this purpose a support plate disposed at an adjustable distance from said device and against which the clamp can be pressed, by a base presenting slots each of which is intended to receive a winding crown arranged upside down, in the goal that Fon can chase the outer extremity of the rod into it once cut, by a device having rotating rollers in front of which a slider can move in the goal that Fon can engage between this and the rollers the rod driven into the crown to screw it down.

La fig. 6 montre un autre ddtail en coupe. La fig. 7 montre une variante de d6tail, et la fig. 8 est une coupe par VIII-VIII de la fig. 7. L'outillage reprdsent6 (fig. 1) comprend un socle 1 sur lequel est dispose ä gauche un dispositif 2 pour couper les tiges ä leur longueur exacte et, ä droite, une cuvette 3 pr6sentant un bane 4 dann lequel sont creus6s une serie d'alveoles 5. Sur 1'avant du socle sont disposds (fig. 3 et 4) deux rouleaux 6 tournant hbre- ment avec leur arbre 8 dans des roulements ä billes 7 ; devant ces deux rouleaux peut coulisser sur un guide 9 un coulisseau 10. fig. 6 shows another sectional detail. fig. 7 shows a detail variant, and FIG. 8 is a section through VIII-VIII of FIG. 7. The tool represented (fig. 1) comprises a base 1 on which is arranged on the left a device 2 for cutting the rods to their exact length and, on the right, a basin 3 presenting a bench 4 in which are dug a series of cells 5. On the front of the base are arranged (fig. 3 and 4) two rollers 6 freely rotating with their shaft 8 in ball bearings 7; in front of these two rollers can slide on a guide 9 a slider 10.

Le dispositif 2 pour couper les tiges comprend (fig. 2) un couteau 11 dispos6 entre 1e bäti du dispo- sitif et une plaque fixe 12, de facon ä pouvoir osciller dans un plan vertical fixe ; 13 est une plaque d'appui se prolongeant par une tige 14 filet6e en 15 et pr6sen- The device 2 for cutting the stems comprises (fig. 2) a knife 11 arranged between the frame of the device and a fixed plate 12, so as to be able to oscillate in a fixed vertical plane; 13 is a support plate extending by a threaded rod 14 at 15 and presented

Sur cette tige peut tourner, mais non pas se deplacer axialement, un ecrou 16 ; en toumant celui-ei dans un sens ou dans 1'autre, an approche ou eloigne la plaque d'appui 13 de la plaque 12 ; cette plaque 13 presente un logement 17 dann lequel an peut engager 1'extremite conique 18 (fig. 5) dune pince avec laquelle an saisit la tige ä couper par son bout Interieur, une portee plate 19 de cette pince venant appuyer contre la portee 20 de la tige, portee qui est toujours fix6e avec precision parce quelle sert d'appui au pignon de remontoir, lequel doit se trouver exactement en regard de la fenetre de la platine qui lui permet de traverser celle-ci pour atteindre la roue de couronne. La pince, engagee dans 1e logement 17, 1'extremite ext6rieure de la tige de remontoir traversera 1e trou 21 de la plaque 12 et, si eile est trog longue, viendra se placer dann la trajec- toire du couteau 11. all of the dishes preventing them from turning. On this rod can turn, but not move axially, a nut 16; by turning the latter in one direction or the other, an approach or move away the support plate 13 from the plate 12; this plate 13 has a housing 17 in which an can engage the conical end 18 (fig. 5) of a pliers with which an grasps the rod to be cut by its inner end, a flat surface 19 of this pliers coming to rest against the surface 20 of the stem, a bearing which is always fixed with precision because it serves as a support for the winding pinion, which must be exactly opposite the window of the plate which allows it to pass through it to reach the crown wheel. The clamp, engaged in the housing 17, the outer end of the winding stem will pass through the hole 21 of the plate 12 and, if it is too long, will come to rest in the path of the blade 11.

0n pourra employer pour manipuler la tige, la pince montree en fig. 6 ; celle-ci comprend deux lan- guettes 61astiques 22 entre lesquelles an place la pince et qui sont entour6es par une bague fendue 23 dopt an peut approcher ou eloigner les levres en toumant la manette 24 ; celle-ci est fix & ä l'extr6mite sup6- rieure dune tige rotative 25, en partie filetee et tra- versant la bague. 0n can use to manipulate the rod, the pliers shown in fig. 6; this comprises two 61astic tabs 22 between which an places the clamp and which are entour6es by a split ring 23 dopt an can approach or away the lips by turning the handle 24; the latter is fixed to the upper end of a rotating rod 25, partly threaded and passing through the ring.

0n utilise 1'appareil de la fapn suivante : an place dans chaque alv6ole une couronne toumee sens dessus dessous, puis, une fois la tige coupee ä la longueur voulue au moyen du dispositif qui vient d'etre decrit et en la tenant toujours par la pince, an enfonce son extr6mit6 dans l'une de ces couronnes ; apres quoi an retire la tige et sa couronne en les tenant toujours par la pince, an place la couronne contre les deux rou- leaux 6 ; puis 1e coulisseau 10 qui se trouvait sur la gauche est deplace vers la droite ; dans ce mouvement il fait toumer la couronne sur la tige et effectue 1e vis- sage de celle-ci. The device is used as follows: a crown is placed in each cell, turned upside down, then, once the stem has been cut to the desired length by means of the device which has just been described and still holding it by the forceps, an inserts its extremity in one of these crowns; after which an removes the rod and its crown, still holding them by the pliers, an places the crown against the two rollers 6; then the first slider 10 which was on the left is moved to the right; in this movement it rotates the crown on the stem and performs the first screwing thereof.

Dans la variante des fig. 7 et 8 an a substitu6 aux alv6oles 5 des emplacements limit6s par trois butees 26 dispos6es radialement sur 1e socle, autour d'un cer- cle et dont Pune peut se d6placer e1astiquement sur ce socle. In the variant of FIGS. 7 and 8 years has replaced cells 5 with locations limited by three stops 26 arranged radially on the base, around a circle and one of which can move elastically on this base.
