Fastening device according to claim 2, characterized in that the wedge-shaped piece is housed in a hole formed in said element, the axis of which is perpendicular to that of the hole in which said rod is housed, the end of the hole in which the wedge-shaped piece is housed being tapped and receiving a clamping screw which acts on said piece to press it against the inclined plane formed by the tangential passage formed in the rod. La présente invention a pour objet un dispositif de fixation d'un rail de guidage sur un élément de machine.The present invention relates to a device for fixing a guide rail to a machine element. Les rails de guidage de machines, en particulier de machines-outils, ont l'avantage, par rapport aux coulisses fixes, de faciliter les réparations, les rails usés pouvant être aisément remplacés alors que les coulisses fixes, une fois usées, nécessitent une opération de grattage longue et coûteuse. De plus, la force nécessaire pour assurer le déplacement d'un élément mobile monté sur des rails de guidage est inférieure à celle qui serait nécessaire pour déplacer ce même élément s'il était monté sur une coulisse fixe, du fait que des organes de roulement, tels que des rouleaux ou des aiguilles, peuvent être interposés entre les rails et l'élément mobile.The guide rails of machines, in particular of machine tools, have the advantage, compared to the fixed slides, of facilitating repairs, the worn rails being able to be easily replaced whereas the fixed slides, once worn, require an operation long and expensive scratching. In addition, the force required to ensure the movement of a mobile element mounted on guide rails is less than that which would be necessary to move this same element if it were mounted on a fixed slide, due to the fact that rolling elements , such as rollers or needles, can be interposed between the rails and the movable element. Les rails de guidage sont fixés sur les éléments de la machine qui les portent (bâti fixe ou chariot mobile), le plus généralement, à l'aide de vis qui les traversent et qui prennent dans lesdits éléments. Cette disposition a pour inconvénient de nécessiter que les trous de fixation des rails soient pratiqués, dans le bâti de la machine, soit sur la base de données techniques, soit en employant le rail même comme gabarit de perçage. Ces trous doivent en outre avoir une haute précision. De plus, les rails qui subiraient une déformation, lors du traitement thermique (trempe), supérieure au jeu entre les vis de fixation et les trous devraient être éliminés. Ce cas peut également se présenter lors des révisions des rails de guidage.The guide rails are fixed to the elements of the machine which carry them (fixed frame or mobile carriage), most generally by means of screws which pass through them and which engage in said elements. This arrangement has the drawback of requiring that the holes for fixing the rails be made, in the frame of the machine, either on the basis of technical data, or by using the rail itself as a drilling template. These holes must also have a high precision. In addition, the rails which would undergo a deformation, during the heat treatment (quenching), greater than the clearance between the fixing screws and the holes should be eliminated. This case can also arise during revisions of the guide rails. Le but de la présente invention est d'éliminer ces inconvénients en fournissant un moyen simple, efficace et bon marché, pour fixer des rails de guidage sur un élément de machine, permettant d'assurer l'interchangeabilité des rails de guidage, comme aussi de compenser le jeu supplémentaire dû aux retouches s'effectuant à l'occasion de révisions.The object of the present invention is to eliminate these drawbacks by providing a simple, effective and inexpensive means for fixing guide rails to a machine element, making it possible to ensure the interchangeability of the guide rails, as well as of compensate for the additional clearance due to retouching carried out during revisions. Ce but est atteint grâce aux moyens définis dans la revendication 1.This object is achieved by the means defined in claim 1. Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.The drawing shows, by way of example, one embodiment of the subject of the invention. La fig. 1 est une coupe transversale d'une partie d'un bâti de machine-outil et d'un chariot mobile se déplaçant sur ce bâti;fig. 1 is a cross-section of part of a machine tool frame and a movable carriage moving on this frame; la fig. 2 est une vue en plan d'un détail, à plus grande échelle;fig. 2 is a plan view of a detail, on a larger scale; la fig. 3 est une coupe suivant la ligne III-III de la fig. 2;fig. 3 is a section along the line III-III of FIG. 2; la fig. 4 est une coupe suivant la ligne IV-IV de la fig. 3, et la fig. 5 est une coupe suivant la ligne V-V de la fig. 3.fig. 4 is a section along line IV-IV of FIG. 3, and fig. 5 is a section along the line V-V of FIG. 3. Le bâti de machine représenté est désigné par 1. Il présente deux feuillures 2, se faisant face, dans lesquelles sont disposés deux rails de guidage 3 avec lesquels coopèrent, avec interposition d'aiguilles de roulement 4, deux rails de guidage 5 fixés à un chariot mobile 6 de la machine. Les deux rails de guidage 5 sont fixés au chariot 6 chacun par des vis 7, qui les traversent et qui prennent dans le chariot 6.The machine frame represented is designated by 1. It has two rabbets 2, facing each other, in which are arranged two guide rails 3 with which cooperate, with the interposition of roller needles 4, two guide rails 5 fixed to a mobile carriage 6 of the machine. The two guide rails 5 are fixed to the carriage 6 each by screws 7, which pass through them and which take in the carriage 6. Quant aux rails de guidage 3, portés par le bâti 1, ils sont fixés chacun à l'aide de plusieurs dispositifs de fixation dont un seul a été représenté, étant tous identiques. Chacun de ces dispositifs de fixation comprend une bride de serrage 8 disposée dans un dégagement 9 du bâti 1 et dans un dégagement 10 du rail 3, chevauchant ces deux éléments. La bride de serrage 8 est traversée par un tirant 11, en forme de tige, logé dans un trou borgne 12 ménagé dans le bâti 1. La tige 11 formant tirant a une extrémité taraudée en 13 sur laquelle est vissé un écrou 14, prenant appui sur la bride 8. Cet écrou permet le montage du dispositif.As for the guide rails 3, carried by the frame 1, they are each fixed using several fixing devices of which only one has been shown, being all identical. Each of these fixing devices comprises a clamping flange 8 arranged in a clearance 9 of the frame 1 and in a clearance 10 of the rail 3, overlapping these two elements. The clamping flange 8 is traversed by a tie rod 11, in the form of a rod, housed in a blind hole 12 formed in the frame 1. The rod 11 forming the tie rod has a threaded end at 13 on which is screwed a nut 14, bearing on the flange 8. This nut enables the assembly of the device. La tige 11 présente un passage tangentiel 15 incliné par rapport à l'axe de la tige et qui s'étend jusqu'à mi-épaisseur de celle-ci, comme le montre en particulier la fig. The rod 11 has a tangential passage 15 inclined with respect to the axis of the rod and which extends to mid-thickness thereof, as shown in particular in FIG. 5. Ce passage 15 est traversé par une pièce en forme de coin 16 logée dans un trou borgne 17, perpendiculaire au trou 12, ménagé dans le bâti 1. Ce coin 16 prend appui sur le plan incliné 18 (fig. 3) que ménage le passage tangentiel 15 de la tige 11. L'extrémité du trou 17 est taraudée et reçoit une vis 19 qui prend appui sur la pièce en forme de coin 16 pour la presser dans le sens de la flèche 20 (fig. 3) contre le plan incliné 18, ce qui tend à déplacer la tige 11 dans le sens de la flèche 21, assurant ainsi le serrage de la bride 8 sur le rail 3, la bride prenant par ailleurs appui sur le bâti 1. Le rail 3 est ainsi pressé contre la surface de portée que constitue la base de la feuillure 2. Un contre-écrou 22, vissé sur la vis 19, permet de bloquer cette dernière.5. This passage 15 is traversed by a wedge-shaped piece 16 housed in a blind hole 17, perpendicular to the hole 12, made in the frame 1. This wedge 16 bears on the inclined plane 18 (fig. 3) that household the tangential passage 15 of the rod 11. The end of the hole 17 is threaded and receives a screw 19 which rests on the wedge-shaped piece 16 to press it in the direction of the arrow 20 (fig. 3) against the inclined plane 18, which tends to move the rod 11 in the direction of the arrow 21, thus ensuring the tightening of the clamp 8 on the rail 3, the clamp moreover resting on the frame 1. The rail 3 is thus pressed against the bearing surface that constitutes the base of the rabbet 2. A lock nut 22, screwed onto the screw 19, makes it possible to block the latter. Le montage du dispositif s'effectue en engageant tout d'abord la tige 11, dépourvue de son écrou 14, dans son logement 12, puis en engageant le coin 16 dans son logement 17 et en lui faisant traverser le passage 15 de la tige 11. La bride 8 est ensuite engagée sur la tige 11 et l'écrou 14 vissé sur l'extrémité de celle-ci, ce qui tire cette dernière vers le haut et amène le plan incliné 18 que ménage le passage tangentiel 15 à coopérer avec le coin 16. La vis 19 est alors vissée de façon à pousser le coin 16 contre le plan incliné 18. Enfin, le contre-écrou 22 est bloqué.The assembly of the device is carried out by first engaging the rod 11, devoid of its nut 14, in its housing 12, then by engaging the wedge 16 in its housing 17 and making it pass through the passage 15 of the rod 11 The flange 8 is then engaged on the rod 11 and the nut 14 screwed onto the end of the latter, which pulls the latter upwards and causes the inclined plane 18 which the tangential passage 15 provides to cooperate with the wedge 16. The screw 19 is then screwed so as to push the wedge 16 against the inclined plane 18. Finally, the lock nut 22 is blocked. Il est à remarquer que les rails 5, représentés comme étant fixés sur le chariot 6 à l'aide de vis traversantes 7, pourraient aussi bien être fixés par des dispositifs à brides, tout comme les rails 3 sur le bâti 1. Toutefois, dans ce cas, pour des raisons d'accessibilité, le serrage ne sera pas assuré par un dispositif à coin mais, par exemple, par un dispositif à vis et écrou.It should be noted that the rails 5, shown as being fixed on the carriage 6 by means of through screws 7, could equally well be fixed by flanged devices, just like the rails 3 on the frame 1. However, in In this case, for reasons of accessibility, the tightening will not be ensured by a wedge device but, for example, by a screw and nut device. Grâce à la présente disposition, les rails de guidage n'ont pas à présenter de trous devant coïncider avec des trous de l'élément de la machine qui les supporte. Ils peuvent être remplacés rapidement en cas d'usure, ne nécessitant aucun perçage comme c'est le cas avec le mode de fixation classique par vis traversantes.Thanks to the present arrangement, the guide rails do not have to have holes which must coincide with holes in the element of the machine which supports them. They can be replaced quickly in case of wear, requiring no drilling as is the case with the classic fixing method by through screws. Les avantages de cette disposition sont donc les suivants.The advantages of this arrangement are therefore as follows. Les ennuis dus aux déformations de trempe (position des entre-axes des trous de fixation) sont éliminés.Problems due to quenching deformations (position of the fixing hole centers) are eliminated. Les rails sont interchangeables et l'usure peut être rattrapée lors des révisions.The rails are interchangeable and wear can be taken up during revisions. Les perçages sont supprimés, avec les risques inhérents à la trempe.Drillings are eliminated, with the risks inherent in quenching. Le montage est facilité.Assembly is made easy. Les jeux éventuels, après une période de rodage, peuvent être repris aisément.Any play, after a break-in period, can be easily taken up. 55 1010 1515 2020 2525 3030 3535 4040 4545 5050 5555 6060 6565 RR 1 feuille dessins1 drawing sheet
