Description
Rectifieuse On connaît des rectifieuses présentant un porte-meule à bascule qui permettent, par exemple, la rectification d'une des faces de bagues dont le trou a préalablement été rectifié sur la même machine.
Il existe également des rectifieuses dont la poupée porte-meule est montée sur des roulements axiaux per mettant un mouvement de va-et-vient mais pas un mou vement radial.
La rectifieuse faisant l'objet de la présente invention est caractérisée par au moins un porte-meule monté sur une bascule pivotant sur des roulements qui permettent simultanément les mouvements axiaux et radiaux.
Le dessin représente, à titre d'exemple, une forme d'exécution de la rectifieuse selon l'invention.
La fig. 1 est une coupe longitudinale de la bascule. La fig. 2 est une coupe transversale perpendiculaire à l'axe d'oscillation de la bascule.
La fig. 3 est une coupe perpendiculaire à l'axe d'un des roulements.
La fig. 4 en est une coupe longitudinale.
La fig. 5 est une coupe transversale d'un troisième roulement d'appui de la bascule, alors que la fig. 6 en est une coupe longitudinale.
Dans la fig. 1, la bascule 1, qui porte la meule inté rieure 2, pivote sur les deux roulements radiaux-axiaux 3 et 4. Ces roulements sont posés sur les axes 5 et 6 fixés dans les alésages 7 et 8 du bâti 21 de la machine. Ces rou lements constituent deux points d'appui de la bascule, le troisième appui est constitué par le roulement axial 9 de la fig. 2. Ce roulement, dont le détail est représenté dans les fig. 5 et 6, règle le fonçage de la meule 2 par l'action de la vis 10.
Dans la section droite de la fig. 3, on voit une partie de la bascule 1, dans un alésage de laquelle est maintenue la demi-bague trempée 11 contre laquelle les billes 12 prennent appui. La demi-bague 11 est maintenue contre l'alésage de la bascule 1 par les plaquettes 13, elles- mêmes fixées contre ladite bascule par les vis 14. Le poids de la bascule 1 est suffisant pour appuyer forte ment le roulement contre l'arbre 15 qui est fixe. Le roule ment du deuxième appui est semblable.
Dans la coupe longitudinale de la fig. 4, on retrouve la partie 1 de la bascule, la demi-douille 11, ainsi que les billes 12 et la cage à billes 16. Tout déplacement axial de la bascule 1 fait rouler les billes sur l'arbre 15, alors que les mouvements radiaux de fonçage et de recul de la meule intérieure font tourner les billes autour du même axe.
Le roulement longitudinal à rouleaux des fig. 5 et 6 supporte une partie notable du poids de la bascule 1. Ce roulement qui règle le fonçage de la meule intérieure est monté sur la rotule 20 qui s'appuie sur le bâti 21 de la machine.
L'avantage principal de cette bascule réside dans le fait qu'elle est plus légère qu'une coulisse, qu'elle fonc tionne sans jeu et permet des mouvements de va-et-vient beaucoup plus rapides de la meule.
Une meule 22, de grand diamètre, montée sur une coulisse transversale, non représentée, pourrait effectuer simultanément le meulage des gorges :des mêmes bagues, s'il s'agit de bagues intérieures de roulements.
Grinding machine Grinding machines are known having a rocking wheel holder which allow, for example, the grinding of one of the faces of rings the hole of which has previously been ground on the same machine.
There are also grinding machines whose grinding wheel headstock is mounted on axial bearings allowing a reciprocating movement but not a radial movement.
The grinding machine forming the subject of the present invention is characterized by at least one grinding wheel holder mounted on a rocker pivoting on bearings which simultaneously allow axial and radial movements.
The drawing shows, by way of example, an embodiment of the grinding machine according to the invention.
Fig. 1 is a longitudinal section of the rocker. Fig. 2 is a cross section perpendicular to the axis of oscillation of the rocker.
Fig. 3 is a section perpendicular to the axis of one of the bearings.
Fig. 4 is a longitudinal section thereof.
Fig. 5 is a cross section of a third support bearing of the rocker, while FIG. 6 is a longitudinal section.
In fig. 1, the rocker 1, which carries the internal grinding wheel 2, pivots on the two radial-axial bearings 3 and 4. These bearings are placed on the axes 5 and 6 fixed in the bores 7 and 8 of the frame 21 of the machine. These bearings constitute two support points of the rocker, the third support is constituted by the axial bearing 9 of FIG. 2. This bearing, the detail of which is shown in fig. 5 and 6, adjust the sinking of grinding wheel 2 by the action of screw 10.
In the right section of fig. 3, part of the lever 1 can be seen, in a bore of which the hardened half-ring 11 is held against which the balls 12 bear. The half-ring 11 is held against the bore of the rocker 1 by the plates 13, themselves fixed against said rocker by the screws 14. The weight of the rocker 1 is sufficient to strongly press the bearing against the shaft. 15 which is fixed. The bearing of the second press is similar.
In the longitudinal section of FIG. 4, we find part 1 of the lever, the half-sleeve 11, as well as the balls 12 and the ball cage 16. Any axial movement of the lever 1 causes the balls to roll on the shaft 15, while the movements Inner wheel sinking and recoil radials rotate the balls around the same axis.
The longitudinal roller bearing of fig. 5 and 6 supports a significant part of the weight of the rocker 1. This bearing which regulates the sinking of the inner grinding wheel is mounted on the ball joint 20 which rests on the frame 21 of the machine.
The main advantage of this rocker resides in the fact that it is lighter than a slide, that it operates without play and allows much faster back and forth movements of the grinding wheel.
A grinding wheel 22, of large diameter, mounted on a transverse slide, not shown, could simultaneously perform the grinding of the grooves: the same rings, in the case of inner rings of bearings.
