Description

       

  Machine destinée au perçage de matière dure, notamment de métaux durs  et de .pierres industrielles, pour     filière    et pour l'horlogerie    La présente invention est une machine destinée  au perçage de matière dure au moyen d'un foret  rotatif, notamment de métaux durs, de céramique,  de pierres industrielles, de pierres pour filière ou pour  l'horlogerie.  



  Cette machine est caractérisée par le fait qu'au  moins l'un des deux éléments, support de la pièce à  usiner et foret, est soumis à l'action d'un moyen  leur imprimant un mouvement vibratoire de l'un par  rapport à l'autre.  



  Les     fig.    1, 2 et 3 sont des coupes en élévation  des première, deuxième et troisième formes d'exé  cution.  



  Dans la première     forme    d'exécution     (fig.    1), la  machine comprend un bâti, partiellement représenté,  sur lequel est fixée une poupée 2 dans les paliers 3  de laquelle tourne l'arbre 4 d'une broche dont le  mandrin 5 pince un foret 6. L'arbre est monté avec  un jeu axial limité par deux butées 7. L'indice 8  désigne le rotor d'un moteur électrique à haute fré  quence commandant la rotation de la broche et dont  le stator 9 porte des enroulements 10.  



  La partie supérieure de la poupée présente un  logement dans lequel est monté un électro-aimant  dont la bobine 11, alimentée par un courant alter  natif, entoure un noyau 12. Ce dernier présente un  logement conique 13 dans lequel pénètre la pointe  14 de l'arbre 4.  



  Lors du perçage, la broche est entraînée à grande  vitesse et attaque une pièce à usiner non représentée,  à l'aide d'une matière abrasive. L'électro-aimant  agit sur la pointe 14 de l'arbre et imprime au foret  un mouvement vibratoire axial. Cette vibration per  met une meilleure répartition de     l'abrasif    sur la face  active du foret et sur celle du trou en cours de per-         çage    ; elle améliore considérablement la qualité et  la rapidité de ce dernier.  



       Dàns    la seconde forme d'exécution     (fig.    3), 15  représente le bâti de la machine dans un logement  duquel est monté un électro-aimant dont l'ouverture  de la bobine 16 est traversée par un tasseau 18 qui  y coulisse librement. Ce tasseau est destiné à rece  voir à son     extrémité    supérieure une pièce à usiner  non représentée. Le tasseau est soumis à l'action  d'une bascule 17 à     contrepoids    20 tendant à appli  quer ladite pièce contre le foret qui n'est pas non  plus représenté.

   La bobine est également     alimentée     par un courant     alternatif,    dont le passage imprime au  tasseau une vibration axiale dont l'amplitude est  limitée par l'action de la bascule et par l'amplitude  dudit courant.  



  Dans la troisième forme d'exécution     (fig.    2), l'ar  bre 21 de la broche est commandé     rotativement    par  un jet de fluide dirigé par une buse 22 sur une roue  à aube 23. L'extrémité supérieure 24 de cet arbre  pénètre librement dans l'ouverture centrale 25 d'une  bobine 26.  



  Dans les trois formes d'exécution, la fréquence  des vibrations peut être réglée avec précision par un  régulateur de la fréquence du courant monté dans le  circuit d'alimentation.



  Machine intended for drilling hard material, in particular hard metals and industrial stones, for the industry and for watchmaking. The present invention is a machine intended for drilling hard material by means of a rotary drill, in particular hard metals, of ceramics, industrial stones, stones for the industry or for watchmaking.



  This machine is characterized in that at least one of the two elements, support of the workpiece and drill, is subjected to the action of a means imparting to them a vibratory movement of one with respect to the 'other.



  Figs. 1, 2 and 3 are sections in elevation of the first, second and third embodiments.



  In the first embodiment (fig. 1), the machine comprises a frame, partially shown, on which is fixed a doll 2 in the bearings 3 of which turns the shaft 4 of a spindle whose mandrel 5 clamps a drill 6. The shaft is mounted with an axial play limited by two stops 7. The index 8 designates the rotor of a high frequency electric motor controlling the rotation of the spindle and whose stator 9 carries windings 10.



  The upper part of the doll has a housing in which is mounted an electromagnet whose coil 11, supplied by a native alternating current, surrounds a core 12. The latter has a conical housing 13 into which penetrates the tip 14 of the tree 4.



  During drilling, the spindle is driven at high speed and attacks a workpiece, not shown, using an abrasive material. The electromagnet acts on the tip 14 of the shaft and gives the drill an axial vibratory movement. This vibration allows a better distribution of the abrasive on the active face of the drill and on that of the hole during drilling; it considerably improves the quality and speed of the latter.



       In the second embodiment (fig. 3), 15 shows the frame of the machine in a housing of which is mounted an electromagnet, the opening of the coil 16 of which is crossed by a cleat 18 which slides there freely. This cleat is intended to receive at its upper end a workpiece not shown. The cleat is subjected to the action of a lever 17 with counterweight 20 tending to apply said part against the drill which is not shown either.

   The coil is also supplied by an alternating current, the passage of which imparts an axial vibration to the batten, the amplitude of which is limited by the action of the rocker and by the amplitude of said current.



  In the third embodiment (fig. 2), the shaft 21 of the spindle is rotatably controlled by a jet of fluid directed by a nozzle 22 on a bladed wheel 23. The upper end 24 of this shaft penetrates freely in the central opening 25 of a coil 26.



  In all three embodiments, the frequency of the vibrations can be precisely regulated by a regulator of the frequency of the current mounted in the supply circuit.
