Definitions
- the guiding device 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.
- 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.
- the object of the present invention is to remedy this defect by creating a guiding device which ensures the maintenance of the parts in the machining machine, with a maximum precision for all the diameters of the parts, and eliminates the tedious adjustments during the changes of series 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.
- 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 has a support set ( 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.
- the base 1 has two flat surfaces 12 and 13 ( 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 machined housing with two oblique planar sides and symmetric 8 ( Fig. 2 ) and a vertical bottom plane 9. Also these surfaces form a closed vee housing at the rear, in which is immobilized an intermediate member 11 which will be described later.
- the surfaces 8 will be machined with great precision compared to 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.
- 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.
- a set of intermediate members 11 ( figs 1 , 2 and 4 ) interchangeable, each corresponding to a particular workpiece 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.
- 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 disengaged 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 portion of convex cylindrical surface 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.
- 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.
- 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.
- vee 8 of the support assembly of the guiding device of the present invention comprising two oblique and symmetrical plane flanks
- the term "vee" designates any pair of surfaces arranged to serve as support in two generatrices rectilinear to a cylindrical part, that said surfaces are plane or curved.
Abstract
Description
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.
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.
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 object of the present invention is to remedy this defect by creating a guiding device which ensures the maintenance of the parts in the machining machine, with a maximum precision for all the diameters of the parts, and eliminates the tedious adjustments during the changes of series 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.
Le dispositif selon l'invention est défini par les revendications annexées.The device according to the invention is defined by the appended claims.
On décrit ci-après une forme d'exécution du dispositif selon l'invention, donnée à simple titre d'exemple et illustrée par les dessins annexés, dont :

Fig. 3 is a vertical sectional view along AA of the assembly shown in FIG.Fig. 2 , and - the
Fig. 4 is a perspective view of an intermediate organ that is part of the whole of theFig. 1 .
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. Il comporte un ensemble d'appui (

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 (
On voit à la
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
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
