Abstract
Description
Perfectionnement aux machines-outils, notamment aux fraiseuses. Improvement of machine tools, especially milling machines.
La présente invention a pour objet un perfectionnement aux machines-outils, notamment aux fraiseuses. The present invention relates to an improvement in machine tools, in particular milling machines.
Dans l'industrie aéronautique, on utilise des fraiseuses å portique mobile désignées sous le terme "cinq axes" pour usiner des panneaux en alliage léger. Ces machines sont conçues de telle manière que la fraise puisse être positionnée dans l'espace suivant trois coordonnées cartésiennes (XYZ) mais elle doit de plus etre orientée par rotation autour de deux axes (A,B). In the aeronautical industry, mobile portal milling machines known as "five axes" are used to machine light alloy panels. These machines are designed in such a way that the cutter can be positioned in space according to three Cartesian coordinates (XYZ) but it must also be oriented by rotation around two axes (A, B).
Ces fraiseuses comportent un portique mobile se dépla çant longitudinalement suivant un axe X sur une table formant bâti, ledit portique supportant une traverse sur laquelle se déplace transversalement suivant un axe Y une cuirasse qui porte un plastron monté coulissant verticalement suivant un axe Z, ledit plastron étant muni sur sa face avant de têtes d'usinage pivotant suivant un axe A perpendiculaire aux axes Y èt Z. Dans le dispositif connu l'axe de rotation B est disposé sur le plastron qui se déplace verticalement. These milling machines comprise a mobile gantry moving longitudinally along an axis X on a table forming a frame, said gantry supporting a crosspiece on which a breastplate which crosses transversely along an axis Y carries a faceplate mounted vertically sliding along an axis Z, said faceplate being provided on its front face with machining heads pivoting along an axis A perpendicular to the axes Y and Z. In the known device the axis of rotation B is disposed on the faceplate which moves vertically.
La présente invention a pour objet un perfectionnement qui comporte une disposition originale pour réaliser le cinquième mouvement de rotation. The present invention relates to an improvement which includes an original arrangement for carrying out the fifth rotational movement.
Conformément å la présente invention, la traverse est montée pivotante sur le portique suivant un axe horizontal B perpendiculaire à l'axe X et décalé d'une distance a #par rapport a l'axe de la broche des têtes d'usinage, de telle sorte que le déplacement du plastron correspond à un axe de plongée W. In accordance with the present invention, the cross member is pivotally mounted on the gantry along a horizontal axis B perpendicular to the axis X and offset by a distance a # relative to the axis of the spindle of the machining heads, such so that the movement of the faceplate corresponds to a diving axis W.
Suivant cette disposition, ledéplacement du plastron s'effectue suivant un axe de plongée et non plus suivant un axe vertical. According to this arrangement, the displacement of the faceplate is carried out along a diving axis and no longer along a vertical axis.
Par ailleurs, le cinquième axe est ainsi obtenu a partir d'élémentsconstituant les fraiseuses a quatre axes dans lesquelles la traverse est fixée sur le bâti et il en résulte une grande modularité de construction. De plus, tout l'ensemble basculant est supporté par la traverse, très rigide, pivotant sur des pivots hydrostatiques et de ce fait il en résulte que les torsions dans la traverse sont très réduites du fait de sa commande synchronisée aux deux extrémités. Furthermore, the fifth axis is thus obtained from elements constituting the milling machines with four axes in which the crosspiece is fixed to the frame and this results in a great modularity of construction. In addition, the entire tilting assembly is supported by the very rigid cross member, pivoting on hydrostatic pivots and therefore it results that the twists in the cross member are very reduced due to its synchronized control at both ends.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qu#i va suivre d'un-mode de réalisation et en se référant aux dessins annexés, sur lesquels
- la figure 1 est une vue en élévation latérale d'une fraiseuse perfectionnée suivant l'invention ; et
- la figure 2 est une vue en élévation frontale de la fraiseuse représentée à la figure 1. Other characteristics and advantages of the invention will be better understood on reading the description which will follow of an embodiment and with reference to the appended drawings, in which
- Figure 1 is a side elevational view of an improved milling machine according to the invention; and
- Figure 2 is a front elevational view of the milling machine shown in Figure 1.
Aux figures 1 et 2 on a représenté une fraiseuse qui comporte un portique mobile 1 se déplaçant longitudinalement suivant une direction parallèle à un axe X sur une table 2 formant un bâti supportant la machine. In Figures 1 and 2 there is shown a milling machine which comprises a movable gantry 1 moving longitudinally in a direction parallel to an axis X on a table 2 forming a frame supporting the machine.
Sur le portique 1 est montée pivotante autour d'un axe B une traverse 3, ledit axe B étant perpendiculaire à l'axe X. La traverse 3 pivote å sa partie inférieure dans des paliers hydrostatiques 4; 4a et elle est munie 8 sa partie supérieure d'un axe 5 sur lequel est articulée au moyen d'un palier# 6 une vis rotative 7 engagée dans un moyen d'entrainement 8 monté sur le portique 1. On the gantry 1 is pivotally mounted around an axis B a cross member 3, said axis B being perpendicular to the axis X. The cross member 3 pivots at its lower part in hydrostatic bearings 4; 4a and it is provided 8 its upper part with an axis 5 on which is articulated by means of a bearing # 6 a rotary screw 7 engaged in a drive means 8 mounted on the gantry 1.
Deux vis rotatives 7 sont ainsi disposées de part et d'autre de la traverse pour commander le déplacement angulaire a, de la traverse autour de l'axe B. Two rotary screws 7 are thus arranged on either side of the cross member to control the angular displacement a of the cross member around the axis B.
Sur la traverse 3 est montée coulissante transversalement suivant une direction parallèle å un axe Y une cuirasse 9 qui porte un plastron 10 muni de glissières 11 lui assurant un déplacement coulissant sur ladite cuirasse suivant un axe W perpendiculaire à l'axe Y. On the cross-member 3 is slidably mounted transversely in a direction parallel to an axis Y a breastplate 9 which carries a faceplate 10 provided with runners 11 ensuring a sliding movement on said breastplate along an axis W perpendicular to the axis Y.
Le plastron 10 est muni sur sa face avant de têtes d'usinage notamment de fraisage 12 susceptibles de pivoter autour d'un axe
A perpendiculaire aux axes Y et W, lesdites testes d'usinage présentant à leur partie inférieure une broche 13 sur laquelle est monté un outil notamment de fraisage.The faceplate 10 is provided on its front face with machining heads, in particular milling heads 12 capable of pivoting about an axis
A perpendicular to the axes Y and W, said machining tests having at their lower part a spindle 13 on which is mounted a tool in particular for milling.
Ainsi qu'il est montré aux figures 1 et 2, l'axe de rotation B de la traverse est perpendiculaire à l'axe X .et il est décalé d'une distance a par rapport à l'axe de la broche 13 des têtes d'usinage 12, de telle sorte que le déplêcement-combiné du plastron 10 portant les têtes d'usinage s'effectue suivant un axe de plongée W. As shown in Figures 1 and 2, the axis of rotation B of the cross is perpendicular to the axis X. And it is offset by a distance a relative to the axis of the pin 13 of the heads machining 12, so that the combined displacement of the faceplate 10 carrying the machining heads takes place along a plunging axis W.
L'axe de plongée W qui est représenté dans une position verticale à la figure 1 peut occuper différentes positions angulaires en corrélation avec ltangle de pivotement or de la traverse 3 autour de l'axe B. The diving axis W which is represented in a vertical position in FIG. 1 can occupy different angular positions in correlation with the pivot angle or of the cross-member 3 around the axis B.
Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art au dispositif qui vient d'être décrit sans sortir du cadre de l'invention. Of course, various modifications can be made by those skilled in the art to the device which has just been described without departing from the scope of the invention.
