Description

  

      Macbine    à couper.    La présente invention a pour objet une  machine à couper, caractérisée en ce qu'elle  comprend un organe de coupe solidaire d'un  support susceptible d'osciller autour d'un axe  de rotation horizontal, ledit support étant  monté sur un bâti comportant une tête orien  table apte à pivoter autour d'un axe de rota  tion vertical, en vue de faire varier la posi  tion relative     dudit    axe de rotation horizontal  du     support    par rapport à la pièce à couper.  



  Le dessin annexé montre, schématiquement  et à titre d'exemple, une forme d'exécution  de la machine selon l'invention.  



  La,     fig.    1 en est une vue de profil,  la     fig.    2 une vue de face et  la     fig.    3 une vue en plan.  



  La machine représentée comprend un bâti  constitué par une colonne 1 coudée à 90  en  viron dans sa partie supérieure en vue de  former un bras horizontal 2. L'extrémité de  ce bras est agencée pour supporter une tête 3,  laquelle est montée à l'extrémité dudit bras  de façon que ce dernier forme avec ladite  tête un ensemble rigide. La tête 3, constituant  un<B>U</B> renversé, est liée au bâti au moyen d'un  pivot qu'elle présente au milieu de la partie  réunissant ses deux branches, en vue de lui  permettre des déplacements angulaires par  rapport au bâti; sa fixation est assurée par  un dispositif de blocage que l'on     manoeuvre     manuellement à l'aide d'une clé 4.

   Il suffit  de desserrer ledit dispositif pour provoquer  le pivotement de la tête 3, laquelle est ensuite    bloquée dans la     position    choisie en resserrant  ce dispositif. En vue de mesurer exactement  le déplacement angulaire imprimé à la tête 3,  cette dernière et le     bras    2 présentent chacun  une portée cylindrique de même diamètre, les  deux portées étant     placées    en regard l'une de  l'autre et disposées concentriquement, la pre  mière présentant une graduation; la seconde  un index.  



  La tête 3 comprend, à l'extrémité, de cha  cune de ses deux branches, un palier destiné  à supporter l'une des extrémités d'un axe<B>3"</B>  constituant le pivot d'un support oscillant 5  auquel est fixé, d'une part, l'organe de coupe  et, d'autre part, un moteur électrique 6, le  quel est destiné à     actionner.    -ledit organe de  coupe. Ce dernier, le support et le moteur  forment un     ensemble    maintenu en équilibre  entre les deux branches de la tête 3, les       mouvements    d'oscillation étant imprimés ma  nuellement à l'aide d'un manche 7, à poignée       7a,    fixé au support 5. L'organe de coupe est  constitué, dans la machine représentée au des  sin, par un disque.

   Il est entendu que ce dis  que pourrait être remplacé, en considérant la  même machine, par une scie circulaire par  exemple, en vue de     travailler    le bois notam  ment. L'organe de coupe est maintenu au sup  port 5 par l'intermédiaire d'un bras 8 com  prenant un palier à roulement destiné à sup  porter l'arbre sur lequel est monté ledit or  gane, ce dernier étant en outre enfermé dans  un carter de protection 9. La     transmission     entre le moteur et l'organe de coupe s'effectue      au moyen d'une courroie     trapézdidale    10 pas  sant sur (les poulies 11, 11a.  



  Le bâti comprend de plus une table 12  sur laquelle la pièce à travailler est mainte  nue par exemple entre les mâchoires d'un  étau.



      Macbine to cut. The present invention relates to a cutting machine, characterized in that it comprises a cutting member integral with a support capable of oscillating about a horizontal axis of rotation, said support being mounted on a frame comprising a head Orien table capable of pivoting about a vertical axis of rotation, in order to vary the relative position of said horizontal axis of rotation of the support with respect to the workpiece.



  The appended drawing shows, schematically and by way of example, an embodiment of the machine according to the invention.



  The, fig. 1 is a side view, FIG. 2 a front view and FIG. 3 a plan view.



  The machine shown comprises a frame consisting of a column 1 bent at about 90 in its upper part in order to form a horizontal arm 2. The end of this arm is designed to support a head 3, which is mounted at the end. of said arm so that the latter forms a rigid assembly with said head. The head 3, constituting an inverted <B> U </B>, is linked to the frame by means of a pivot which it presents in the middle of the part joining its two branches, in order to allow it to move angularly relative to to the frame; it is secured by a locking device that is operated manually using a key 4.

   It suffices to loosen said device to cause the pivoting of the head 3, which is then locked in the chosen position by tightening this device. In order to measure exactly the angular displacement imparted to the head 3, the latter and the arm 2 each have a cylindrical bearing surface of the same diameter, the two bearing surfaces being placed opposite one another and arranged concentrically, the first with a graduation; the second an index.



  The head 3 comprises, at the end of each of its two branches, a bearing intended to support one of the ends of an axis <B> 3 "</B> constituting the pivot of an oscillating support 5 to which is fixed, on the one hand, the cutting member and, on the other hand, an electric motor 6, which is intended to actuate said cutting member. The latter, the support and the motor form an assembly maintained in equilibrium between the two branches of the head 3, the oscillating movements being imprinted manually by means of a handle 7, with handle 7a, fixed to the support 5. The cutting member is formed, in the machine represented in the sines, by a disc.

   It is understood that this saying could be replaced, considering the same machine, by a circular saw for example, with a view to working wood in particular. The cutting member is held on the support 5 by means of an arm 8 comprising a rolling bearing intended to support the shaft on which said or gane is mounted, the latter being further enclosed in a housing protection 9. The transmission between the engine and the cutting unit is effected by means of a trapezoidal belt 10 not on (the pulleys 11, 11a.



  The frame further comprises a table 12 on which the workpiece is held bare, for example between the jaws of a vice.
