Description

Domaine techniqueTechnical area

L'usinage de certains outils cylindriques en matériaux durs, comme des forets de petit diamètre, plus ou moins longs, doit souvent répondre à des exigences de précision extrêmement grandes. Or, c'est un domaine de la technique qui évolue vers une diminution des nombres de pièces des séries ce qui pose le problème d'une réduction des temps non productifs causés par l'adaptation des outillages aux changements de série. Cette adaptation doit évidemment être réalisée en garantissant l'extrême qualité du positionnement et du guidage des pièces usinées, à chaque modification du dispositif de guidage.The machining of some cylindrical tools made of hard materials, such as small diameter drills, which are more or less long, must often meet extremely high precision requirements. However, it is a field of technology that is evolving towards a decrease in the number of pieces in the series, which poses the problem of a reduction of the non-productive times caused by the adaptation of the tools to the changes of series. This adaptation must of course be achieved by ensuring the extreme quality of the positioning and guiding of the machined parts, each modification of the guiding device.

Etat de la techniqueState of the art

Dans les machines usuelles, le dispositif de guidage comporte généralement une partie fixe avec deux flancs plans en forme de vé, dans laquelle la pièce à usiner est engagée et guidée, et une partie mobile, le doigt d'appui qui presse la pièce dans le vé en garantissant une rotation dont la qualité ne dépend plus alors que de la circularité de la pièce à usiner elle-même. Lors d'un changement de série, le vé de positionnement doit être changé puisque le diamètre d'outil de la série nouvelle diffère de celui de la série précédente, et sa hauteur de positionnement doit être ajustée avec grande précision pour assurer une position parfaite de l'axe de rotation. Ce travail de réglage de la position du vé, selon trois degrés de liberté au minimum, est consommateur de temps et diminue ainsi la productivité de la machine toute entière. Finalement, il réduit la versatilité du système de production en ne le rendant attractif que pour de très longues séries.In conventional machines, the guiding device generally comprises a fixed part with two planar V-shaped sidewalls, in which the workpiece is engaged and guided, and a movable part, the bearing finger which presses the part into the This guarantees a rotation whose quality no longer depends on the circularity of the workpiece itself. During a change of series, the positioning vee must be changed since the tool diameter of the new series differs from that of the previous series, and its positioning height must be adjusted with great precision to ensure a perfect position. the axis of rotation. This work of adjusting the position of the vee, with three degrees of freedom to a minimum, is time consuming and thus reduces the productivity of the entire machine. Finally, it reduces the versatility of the production system by making it attractive only for very long runs.

Divulgation de l'inventionDisclosure of the invention

La présente invention a pour but de remédier à ce défaut en créant un dispositif de guidage qui assure le maintien des pièces dans la machine d'usinage, avec une précision maximale pour tous les diamètres des pièces, et supprime les réglages fastidieux lors des changements de série de façon à minimiser les temps improductifs. Par conséquent, le dispositif objet de l'invention permet notamment de gérer dans des conditions concurrentielles le traitement de séries plus courtes que jusqu'à maintenant.The present invention aims to remedy this defect by creating a guiding device which ensures the maintenance of the parts in the machining machine, with maximum accuracy for all part diameters, and eliminates tedious adjustments during series changes to minimize unproductive time. Consequently, the device that is the subject of the invention makes it possible in particular to manage, in competitive conditions, the processing of shorter series than until now.

A cet effet la présente invention concerne un dispositif de guidage de précision dans une machine d'usinage de pièces cylindriques, caractérisé en ce qu'il comporte un ensemble d'appui définissant un axe fixe pour lesdites pièces et comprenant un vé solidaire d'une embase, un jeu d'organes intermédiaires interchangeables adaptés au vé et correspondant chacun à un diamètre déterminé d'une série desdites pièces cylindriques et un doigt d'appui, pressant la pièce à usiner contre l'organe intermédiaire dans le vé.To this end, the present invention relates to a precision guide device in a machine for machining cylindrical parts, characterized in that it comprises a bearing assembly defining a fixed axis for said parts and comprising a vee integral with a base, a set of interchangeable intermediate members adapted to vee and each corresponding to a given diameter of a series of said cylindrical parts and a bearing finger, pressing the workpiece against the intermediate member in the vee.

Selon un mode d'exécution du dispositif, pour permettre des changements de séries instantanés, chaque organe intermédiaire interchangeable a la forme d'un secteur de couronne ajusté au diamètre des pièces d'une série des pièces à usiner et agencé extérieurement pour être monté dans le vé, entre ce dernier et la pièce cylindrique à usiner, chacun desdits organes intermédiaires pouvant présenter, dans une surface concave cylindrique qui correspond au diamètre de la pièce, des facettes d'appui ajustées avec précision pour recevoir les pièces de la série auquel cet organe est destiné, et une portion de surface cylindrique convexe exactement coaxiale auxdites facettes d'appui concaves et destinée à être appuyée contre les flancs du vé.According to one embodiment of the device, to allow changes in instantaneous series, each interchangeable intermediate member has the shape of a ring sector adjusted to the diameter of the parts of a series of workpieces and arranged externally to be mounted in the vee, between the latter and the cylindrical part to be machined, each of said intermediate members being able to present, in a concave cylindrical surface which corresponds to the diameter of the part, support facets precisely adjusted to receive the parts of the series to which this member is intended, and a portion of convex cylindrical surface exactly coaxial with said concave bearing facets and intended to be supported against the flanks of the vee.

Selon une variante du dispositif, dans chaque organe intermédiaire, ladite portion de surface cylindrique convexe est une face extérieure formant la tranche d'une bride radiale de l'organe intermédiaire, ce dernier étant fixé à l'embase dans le vé par une plaquette munie d'un trou pour une vis de fixation à l'embase et de deux trous pour des goupilles de positionnement de la plaquette, ces goupilles étant engagées dans l'embase en dehors du vé.According to a variant of the device, in each intermediate member, said portion of convex cylindrical surface is an outer face forming the edge of a radial flange of the intermediate member, the latter being fixed to the base in the vee by a plate provided a hole for a fastening screw to the base and two holes for the positioning pins of the wafer, these pins being engaged in the base outside the vee.

Le doigt d'appui peut être fixé sur un étrier pivotant sur l'embase, autour d'un axe exactement perpendiculaire à celui défini par les plans internes du vé, et être pressé contre la pièce à usiner.The support finger can be fixed on a bracket pivoting on the base, about an axis exactly perpendicular to that defined by the internal planes of the vee, and be pressed against the workpiece.

Description détaillée de modes d'exécution de l'inventionDetailed description of embodiments of the invention

Le dispositif de guidage représenté au dessin fait partie d'une machine d'usinage de pièces cylindriques telles que des forets en matériau dur dont le profil doit être meulé ou rectifié avec une extrême précision. II comporte un ensemble d'appui (fig. 1 et 2) monté sur une base machine 1. L'ensemble d'appui des fig. 1 et 2 est agencé pour maintenir selon un axe rigidement déterminé des pièces à usiner 2, soit des outils de forage comme dit plus haut. II comporte une embase 3 fixée sur la base machine 1 par un lardon de serrage 4 et une vis de blocage 5. Pour cela, la base 1 présente deux surfaces planes 12 et 13 (fig. 2), rigoureusement planes et perpendiculaires, sur lesquelles viennent s'appliquer deux faces planes correspondantes usinées à la partie inférieure de l'embase 3. L'embase 3 présente encore, à sa partie antérieure et supérieure un logement usiné avec deux flancs plans obliques et symétriques 8 (fig. 2) et un fond vertical également plan 9. Ces surfaces forment un logement de vé fermé à l'arrière, dans lequel est immobilisé un organe intermédiaire 11 qui sera décrit plus loin. Les surfaces 8 seront usinées avec grande précision par rapport aux faces 12 et 13 de positionnement de l'embase 3 sur la machine. Elles constituent la référence de positionnement de l'outil 2 à usiner sur la machine. Quant à la face 9, elle sert de référence d'appui dans le sens axial pour l'organe intermédiaire 11 et doit donc être plane et parfaitement perpendiculaire à l'axe défini par le vé 8.The guiding device shown in the drawing is part of a machine for machining cylindrical parts such as drills hard material whose profile must be ground or rectified with extreme precision. It comprises a support assembly ( Fig. 1 and 2 ) mounted on a machine base 1. The support assembly of Fig. 1 and 2 is arranged to maintain according to a rigidly determined axis of the workpieces 2, or drilling tools as mentioned above. It comprises a base 3 fixed on the machine base 1 by a clamping bolt 4 and a locking screw 5. For this, the base 1 has two flat surfaces 12 and 13 (FIG. Fig. 2 ), rigorously flat and perpendicular, on which are applied two corresponding flat faces machined to the lower part of the base 3. The base 3 still has, at its front and upper part a housing machined with two oblique and symmetrical planar flanks 8 ( Fig. 2 ) and a vertical bottom plane 9. Also these surfaces form a recess housing closed at the rear, in which is immobilized an intermediate member 11 which will be described later. The surfaces 8 will be machined with great accuracy with respect to the faces 12 and 13 for positioning the base 3 on the machine. They constitute the positioning reference of the tool 2 to be machined on the machine. As for the face 9, it serves as support reference in the axial direction for the intermediate member 11 and must be flat and perfectly perpendicular to the axis defined by the vee 8.

Comme on le voit encore aux fig. 1 à 3, la pièce 2 est maintenue en appui par rapport au vé 8 et 9 par un doigt 14 fixé, par l'intermédiaire d'un élément 14', à un étrier 15 pivotant autour d'un axe 16 par rapport à l'embase 3. L'utilisation d'un doigt d'appui 14 fixé sur un étrier 15 perpendiculairement à la pièce à usiner est connue en soi dans des machines conventionnelles. On sait que de tels étiers sont souvent à commande hydraulique ou pneumatique par un piston 6 logé dans une chambre ménagée dans l'embase et alimentée par des raccords tels que 17, de manière à presser le doigt 14 contre la pièce 2 à l'encontre d'un ressort 18 de dégagement.As we still see Fig. 1 to 3 the piece 2 is held in abutment with respect to the vee 8 and 9 by a finger 14 fixed, via an element 14 ', to a stirrup 15 pivoting about an axis 16 relative to the base 3 The use of a support finger 14 fixed to a stirrup 15 perpendicular to the workpiece is known per se in conventional machines. It is known that such chains are often hydraulically or pneumatically controlled by a piston 6 housed in a chamber formed in the base and fed by connectors such as 17, so as to press the finger 14 against the piece 2 against a release spring 18.

Pour éliminer les manoeuvres d'ajustage et de réglage au moment d'un changement de série de pièces à usiner on associe à l'ensemble d'appui des fig. 1 et 2 un jeu d'organes intermédiaires 11 (figs 1, 2 et 4) interchangeables, correspondant chacun à un diamètre de pièce à usiner particulier. Ainsi, pour adapter l'ensemble d'appui à une série de pièces à usiner d'un diamètre donné, un organe 11 correspondant à ce diamètre est monté entre le doigt d'appui 14 et les faces 8 et 9 du vé. Il est maintenu par une plaquette de positionnement 19 fixée à l'embase par une vis 20 et deux goupilles 21.To eliminate the adjustment and adjustment maneuvers at the time of a change of series of workpieces is associated with the support assembly of Fig. 1 and 2 a set of intermediate members 11 ( figs 1 , 2 and 4 ) interchangeable, each corresponding to a particular workpiece diameter. Thus, to adapt the support assembly to a series of workpieces of a given diameter, a member 11 corresponding to this diameter is mounted between the bearing finger 14 and the faces 8 and 9 of the vee. It is held by a positioning plate 19 fixed to the base by a screw 20 and two pins 21.

L'organe intermédiaire 11, en un matériau de haute résistance, a la forme d'un secteur de couronne cylindrique avec un évidement 22 en arc de cylindre concave qui détermine l'axe correspondant au diamètre de la pièce à usiner pour laquelle l'organe est conçu (fig. 4). Pour réaliser le meilleur guidage possible, la surface 22 est dégagée et seules quatre facettes cylindriques concaves 23 sont maintenues dans des positions symétriques rigoureusement contenues dans une même surface cylindrique. L'organe 11 comporte en outre une bride radiale 24 limitée par une portion de surface cylindrique convexe 25 destinée à s'appuyer contre les faces 8 du vé. La pièce 11 étant un secteur de couronne, sa réalisation peut être faite avec la plus grande précision par des opérations de rectification cylindrique intérieure et extérieure. C'est le diamètre de la pièce à usiner 2 qui détermine le diamètre de la surface 23, donc le choix de l'organe intermédiaire 11, et par conséquent la position de l'axe commun des surfaces 23 et 25 dans le vé 8, cette position étant invariable.The intermediate member 11, made of a high-strength material, has the shape of a cylindrical ring sector with a recess 22 in a concave cylinder arc which determines the axis corresponding to the diameter of the workpiece for which the member is designed ( Fig. 4 ). To achieve the best possible guidance, the surface 22 is unobstructed and only four concave cylindrical facets 23 are held in symmetrical positions rigorously contained in the same cylindrical surface. The member 11 further comprises a radial flange 24 limited by a convex cylindrical surface portion 25 intended to bear against the faces 8 of the vee. Since part 11 is a crown sector, it can be made with the greatest precision by internal and external cylindrical grinding operations. It is the diameter of the workpiece 2 which determines the diameter of the surface 23, therefore the choice of the intermediate member 11, and consequently the position of the common axis of the surfaces 23 and 25 in the vee 8, this position being invariable.

On voit à la fig. 1 que la plaquette 19 est pressée par la vis 20 contre la face antérieure de la bride 24, laquelle est par conséquent pressée contre la face 9 du logement formant le vé 8.We see at the Fig. 1 that the plate 19 is pressed by the screw 20 against the front face of the flange 24, which is therefore pressed against the face 9 of the housing forming the vee 8.

Un changement de série implique le changement de la pièce 11 tenue par la plaquette 19. La vis 20 assure le blocage de l'ensemble et les goupilles 21 servent en plus à reprendre le couple de frottement en rotation lors du serrage de la vis 20, lequel aurait, sinon la tendance à faire tourner la pièce 11.A change of series involves the change of the piece 11 held by the wafer 19. The screw 20 locks the assembly and the pins 21 serve in addition to take up the rotational friction torque when tightening the screw 20, which would have, if not the tendency to turn the piece 11.

L'ensemble d'appui décrit ci-dessus maintient donc les pièces à usiner dans une position telle que l'axe de la pièce est rigoureusement déterminé par rapport à l'embase, et donc par rapport à la base machine 1. Pour que l'usinage des pièces puisse être réalisé avec la précision voulue, il faut encore que l'entraînement de la pièce se fasse de telle manière que cette dernière tourne effectivement autour de l'axe défini par l'ensemble d'appui. La machine d'usinage sera pourvue d'une poupée ayant une broche dans laquelle la pièce à usiner sera fixée et par laquelle elle sera entraînée. Le cas échéant, cette poupée pourra être d'un type à broche flottante.The support assembly described above thus maintains the workpieces in a position such that the axis of the workpiece is strictly determined with respect to the base, and therefore with respect to the machine base 1. machining parts can be achieved with the desired accuracy, it is still necessary that the drive of the part is done in such a way that the latter actually turns around the axis defined by the support assembly. The machining machine will be provided with a doll having a spindle in which the workpiece will be fixed and by which it will be driven. If necessary, this doll may be of a floating spindle type.

L'homme du métier comprendra aisément que le vé 8 de l'ensemble d'appui du dispositif de guidage de la présente invention, comportant deux flancs plans obliques et symétriques, peut bien entendu être constitué ou remplacé par une paire de surfaces courbes, concaves ou convexes, et par exemple par deux goupilles. Par conséquent, dans le cadre de la présente invention, le terme "vé" désigne toute paire de surfaces agencées pour servir d'appui selon deux génératrices rectilignes à une pièce cylindrique, que lesdites surfaces soient planes ou courbes.Those skilled in the art will readily understand that the vee 8 of the support assembly of the guiding device of the present invention, comprising two oblique and symmetrical plane flanks, can of course be constituted or replaced by a pair of curved, concave surfaces. or convex, and for example by two pins. Therefore, in the context of the present invention, the term "vee" designates any pair of surfaces arranged to serve as a support in two generatrices rectilinear to a cylindrical part, that said surfaces are flat or curved.
