Description

Dispositif de guidage rectiligne d'un chariot.Device for rectilinear guidance of a carriage.

Dans certaines machines et plus spécialement dans les machines de fonderie, il est nécessaire de guider, par rapport à un bati fixe, des organes mobiles tels que des porte-moules dont il faut commander le rapprochement et l'éloignement pour les opérations de moulage et de démoulage ~ Cette commande est usuellement réalisée au moyen de vérins, le guidage étant réalisé par deux colonnes parallèles sur lesquelles coulissent des organes, chariots ou porte-moules. In certain machines and more particularly in foundry machines, it is necessary to guide, with respect to a fixed frame, movable members such as mold carriers, the approximation and the distance of which must be controlled for the molding operations and mold release ~ This command is usually carried out by means of jacks, the guide being produced by two parallel columns on which slide members, carriages or mold carriers.

Le guidage à deux colonnes nécessite une exécution rigoureuse et des colonnes elles-memes et de leur montage sur le b8ti. Or, il existe toujours des tolérances d'exécution qu'il n'est pas possible de tenir pour un court raisonnable et qui, de toute façon, seraient illusoires compte tenu par ailleurs des phénomènes de déformations thermiques (dilatation) qui existent sur des machines de fonderie. Two-column guidance requires rigorous execution of the columns themselves and their mounting on the b8ti. However, there are always execution tolerances which it is not possible to take for a reasonable short and which, in any case, would be illusory taking into account in addition phenomena of thermal deformations (expansion) which exist on machines foundry.

La présente invention entend remédier aux inconvénients d'un tel guidage qui sont le coincement de l'organe mobile ou la nécessité de développer des efforts considérables pour assurer son mouvement avec tous les risques d'usure ou de casse que cela comporte. The present invention intends to remedy the drawbacks of such guidance which are the jamming of the movable member or the need to develop considerable efforts to ensure its movement with all the risks of wear or breakage that this entails.

A cet effet, l'invention a donc pour objet un dispositif de guidage rectiligne pour un chariot ou analogue par rapport à un bctti fixe constitué par deux colonnes parallèles fixées audit bats sur lesquelles le chariot est monté à coulissement.To this end, the invention therefore relates to a rectilinear guide device for a carriage or the like with respect to a fixed bctti constituted by two parallel columns fixed to said bats on which the carriage is slidably mounted.

Selon l'une des caractéristiques de l'lnvention, l'une desdites colonnes est de diamètre plus important que celui de l'autre colonne pour constituer la colonne principale de guidage qui coopère avec au moins deux bagues porteuses du chariot, l'autre colonne coopérant avec une bague porteuse dudit chariot montée sur ce dernier à coulissement dans le plan contenant les axes desdites colonnes et perpendiculairement à ces derniers. According to one of the characteristics of the invention, one of said columns has a larger diameter than that of the other column to constitute the main guide column which cooperates with at least two carrier rings of the carriage, the other column cooperating with a carrier ring of said carriage mounted on the latter sliding in the plane containing the axes of said columns and perpendicular thereto.

Dans un mode préféré de rdalisation, la bague coulissante susdite comporte extérieurement deux méplats parallèles qui coopèrent avec deux faces parallèles d'une lumière prévue dans le chariot. La bague peut etre alors polygonale de manière à présenter plusieurs jeux de méplats à mettre successivement en service.  In a preferred embodiment, the above-mentioned sliding ring externally comprises two parallel flats which cooperate with two parallel faces of a light provided in the carriage. The ring can then be polygonal so as to present several sets of flats to be successively put into service.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif qui permettra d'en dégager les avantages et les caractéristiques secondaires. The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés dans lesquels
- la figure 1 est une vue schématique en coupe du dispositif selon l'invention;
- la figure 2 est une coupe d'un détail de la figure 1 selon la ligne II-II.Reference will be made to the accompanying drawings in which
- Figure 1 is a schematic sectional view of the device according to the invention;
- Figure 2 is a section through a detail of Figure 1 along line II-II.

En se reportant à ces figures, on voit deux colonnes 1 et 2 de guidage d'un chariot 3 fixées à un bati symbolisé par la bride 4. La colonne 1 est de diamètre D nettement plus important que celui d de la colonne 2 et coopère avec deux bagues 5 et 6 du chariot éloignées axialement l'une de l'autre pour donner à ce dernier une stabilité de guidage dans le plan des deux colonnes. On peut, sans sortir du cadre de l'invention, prévoir une seule bague ou plusieurs pour obtenir ce meme résultat de stabilité. Ces bagues 5 et 6 sont donc des bagues porteuses qui supporteront la plus grande partie des efforts appliqués au chariot. Referring to these figures, we see two columns 1 and 2 for guiding a carriage 3 fixed to a frame symbolized by the flange 4. Column 1 is of diameter D significantly larger than that d of column 2 and cooperates with two rings 5 and 6 of the carriage axially spaced from one another to give the latter guiding stability in the plane of the two columns. Without departing from the scope of the invention, it is possible to provide a single ring or more to obtain this same stability result. These rings 5 and 6 are therefore load-bearing rings which will support the greater part of the forces applied to the carriage.

Une troisième bague 7 du chariot coopère avec la colonne 2. A third ring 7 of the carriage cooperates with column 2.

Cette bague 7 a pour fonction, avec la colonne 2, d'empocher une rotation du chariot 3 autour de la colonne 1. Pour prendre en compte les déformations des colonnes 1 et 2 ou du chariot 3 (qui, dans une machine à coquiller, peut etre un chariot porte-moulesdonc soumis à une élévation importante de température par rapport aux colonnes ou au bati) et le faux parallélisme du aux tolérances de fabrication et de montage, la bague 7 est libre par rapport au chariot 3 dans le plan de la figure 1, c'est-à-dire dans le plan des axes des colonnes et perpendiculairement à ces dernières. Pour ce faire, le chariot 3 est pourvu d'une lumière 8 dont l'axe est perpendiculaire aux colonnes et dont les flancs 8a et 8b sont les surfaces de guidage pour la bague 7 pourvue en correspondance de méplats 7a et 7b.Il sera d'ailleurs avantageux de donner une forme polygonale à la bague 7 (par exemple hexagonale) de manière à disposer de deux autres jeux de méplats 7c, 7d, 7e, 7f à mettre en service une fois que les méplats précédents auront subi une usure trop grande. On n'a pas représenté sur les dessins le moyen (par exemple un tenon et une rainure ou un ensemble de vis coopérant avec une rainure de la bague 7) d'immobilisation de la bague 7, par rapport au chariot dans le sens de l'axe de la colonne 2.This ring 7 has the function, with the column 2, of pocketing a rotation of the carriage 3 around the column 1. To take into account the deformations of the columns 1 and 2 or of the carriage 3 (which, in a shell machine, may be a mold carrier carriage therefore subjected to a significant rise in temperature relative to the columns or the frame) and the false parallelism due to manufacturing and assembly tolerances, the ring 7 is free relative to the carriage 3 in the plane of the Figure 1, that is to say in the plane of the axes of the columns and perpendicular to the latter. To do this, the carriage 3 is provided with a light 8 whose axis is perpendicular to the columns and whose sides 8a and 8b are the guide surfaces for the ring 7 provided in correspondence with flats 7a and 7b. '' also advantageous to give a polygonal shape to the ring 7 (for example hexagonal) so as to have two other sets of flats 7c, 7d, 7e, 7f to be put into service once the previous flats have suffered too much wear . The means has not been shown in the drawings (for example a tenon and a groove or a set of screws cooperating with a groove in the ring 7) for immobilizing the ring 7, relative to the carriage in the direction of the column 2.

L'invention trouve une application intéressante dans le domaine de la construction de machinesxoutils. Elle n'est pas limitée à la description qui vient d'en entre donnée mais couvre au contraire toutes les variantes qui pourraient lui 2trie apportées sans sortir de son cadre ni de son esprit.  The invention finds an interesting application in the field of machine tool construction. It is not limited to the description which has just entered, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.
