Description

       

  Machine à     arrondir    le     profil    des dents des roues d'horlogerie.    L'objet de la présente invention est une  machine à arrondir, dans le genre de celles  que l'on- utilise pour arrondir le profil des  dents des roues d'horlogerie.  



  Généralement, les machines de ce genre  ont un arbre monté sur coussinets à     cÔone,    de  vant, et, derrière, à l'autre bout de l'arbre;  une vis à pointe conique sur laquelle l'arbre  pivote et servant à     rattrapper    le jeu qui se  produit par l'usure. Ce système de construc  tion a l'inconvénient que l'arbre se désaxe  par l'usure de la pointe conique de la vis;  en outre, le roulement de l'arbre est trop dur  pour le travail à effectuer.  



  La machine qui fait l'objet de l'invention  a la particularité d'avoir un arbre à portée,  monté sur deux roulements à billes, ainsi que  l'arbre du volant de commande.  



  Le dessin annexé montre, à titre d'exem  ple, une     forme    d'exécution de l'objet de l'in  vention.  



  La     fig.    1 est une vue en élévation et coupe  partielle, la     fig.    2 une vue en plan.  



  La machine représentée comporte un bâti  a, fixé sur un pied     b,        bâti    sur lequel est posé  un jeu de deux coulisses, une horizontale c,    une verticale c'; sur le coulisseau d de cette  dernière est fixé le support é de l'arbre     porte-          outil    f ; dans les têtes du support de l'arbre  sont prévus des logements pour recevoir les  roulements à billes<I>g g',</I> dans lesquels est  ajusté gras l'arbre f; un écrou     h    avec vis de  blocage règle le jeu de l'arbre à portée f et  une poulie est ajustée sur l'arbre.  



  La commande de cette poulie se fait au  moyen d'un volant à gorge relié par une  corde de transmission à la poulie et com  mandé à la main. Ce volant et son support  ne sont pas représentés au dessin; l'arbre de  ce volant est monté de la même façon que  l'arbre f. Un levier l fixé, d'une part, au bâti  <I>a</I> et, d'autre part, au coulisseau<I>d</I> permet de       manoeuvrer    l'arbre     porte-outil    f pour abaisser  la fraise k sur la roue d'horlogerie dont les  dents sont à arrondir. Cette roue est tenue  entre portées sur deux broches et s'appuie  contre un tasseau t interchangeable, vissé  sur un nez prévu à cet effet.

   Le réglage de  la profondeur des dents à arrondir s'opère au  moyen d'une vis v micrométrique portant un  arrêt gradué     n;    la vis v est fixé au coulisseau  dans le même axe que celui-ci; cette vis      passe dans un support s ayant effet de butée;  un index permet une lecture facile et précise  du réglage.



  Machine for rounding the profile of the teeth of watch wheels. The object of the present invention is a rounding machine, of the kind which is used to round the profile of the teeth of watch wheels.



  Generally, machines of this kind have a shaft mounted on conical bearings, at the front, and, behind, at the other end of the shaft; a conical point screw on which the shaft pivots and serving to take up the play that occurs by wear. This construction system has the drawback that the shaft is offset by the wear of the conical tip of the screw; furthermore, the shaft bearing is too hard for the job at hand.



  The machine which is the subject of the invention has the particularity of having a shaft within reach, mounted on two ball bearings, as well as the shaft of the control wheel.



  The accompanying drawing shows, by way of example, an embodiment of the object of the invention.



  Fig. 1 is a view in elevation and partial section, FIG. 2 a plan view.



  The machine shown comprises a frame a, fixed on a foot b, frame on which is placed a set of two slides, one horizontal c, one vertical c '; on the slide d of the latter is fixed the support é of the tool-holder shaft f; housings are provided in the heads of the shaft support to receive the ball bearings <I> g g ', </I> in which the shaft f is greasy; a nut h with locking screw adjusts the shaft play at seat f and a pulley is fitted on the shaft.



  This pulley is controlled by means of a grooved handwheel connected by a transmission cord to the pulley and controlled by hand. This steering wheel and its support are not shown in the drawing; the shaft of this flywheel is mounted in the same way as the shaft f. A lever l fixed, on the one hand, to the frame <I> a </I> and, on the other hand, to the slide <I> d </I> makes it possible to maneuver the tool-holder shaft f to lower the milling cutter k on the watch wheel, the teeth of which are to be rounded. This wheel is held between worn on two pins and rests against an interchangeable t-cleat, screwed on a nose provided for this purpose.

   The depth of the teeth to be rounded is adjusted by means of a micrometric screw v bearing a graduated stop n; the screw v is fixed to the slider in the same axis as the latter; this screw passes through a support s having a stop effect; an index allows easy and precise reading of the setting.
