Description

MACHINE D'EBAVURAGE A PLAT PAR BROSSAGE  FLAT DEBURRING MACHINE BY BRUSHING
DESCRIPTION DESCRIPTION
Domaine technique Technical area
La présente invention a trait à l'amélioration d'un procédé d'ébavurage de pièces planes de grandes dimensions, tel notamment que l'ébavurage et l'ébarbage de pièces oxycoupées.  The present invention relates to the improvement of a deburring process of flat parts of large dimensions, such as deburring and deburring of oxycut pieces.
Etat de la technique State of the art
Il est connu que les procédés actuels d'ébavurage manuel par meulage sont dangereux et fastidieux, que les dispositifs d'émerisage par bande abrasive sont onéreux et souvent inefficaces et que les procédés de grenaillage sont inopérants pour les fortes bavures.  It is known that today's manual deburring processes by grinding are dangerous and tedious, that abrasive belt grinding devices are expensive and often ineffective and that blasting processes are ineffective for severe burrs.
Pour remédier à ces inconvénients, le demandeur a déjà proposé, par le brevet français N° 2792565, un procédé d'ébavurage par brossage comportant un dispositif particulier de montage de brosses métalliques sur un plateau-support rotatif garantissant l'attaque des bavures des pièces sous tous les angles, quelle que soit la complexité géométrique de la pièce à traiter, et avec une puissance transmise aux brosses suffisante. To overcome these drawbacks, the applicant has already proposed, by French Patent No. 2792565, a method of deburring by brushing comprising a particular device for mounting metal brushes on a rotating support plate to ensure the attack of burrs parts from all angles, regardless of the geometric complexity of the workpiece, and with a power transmitted to brushes sufficient.
Plus précisément, ce dispositif comprend une pluralité de brosses diamétralement opposées deux à deux, montées sur un plateau-support rotatif et entraînées en rotation sur elles-mêmes selon des sens successivement inverses, par rapport à un point fixe fictif de référence, de manière à permettre l'attaque des bavures d'une pièce complexe sous tous les angles et dans toutes les directions, lors d'un entraînement linéaire de celle-ci, s'effectuant par un tapis de transport sur lequel elle est posée. Une telle machine donne entièrement satisfaction, mais un constat a été établi au niveau des brosses métalliques. En effet, celles-ci doivent être réglées de manière précise en hauteur pour éviter une usure excessive des brosses ou une altération des pièces traitées tout en tenant compte de l'usure desdites brosses. Les moyens de mesure par coupure d'un rayon photo-électrique ou laser sont peu fiables en raison de l'irrégularité des surfaces des brosses et de l'encrassement rapide des moyens de mesure. De plus, il est fastidieux d'effectuer des mesures manuelles du diamètre des brosses et de les rapporter à un moyen de calcul de la hauteur d'un plateau-support de brosses. More specifically, this device comprises a plurality of diametrically opposite two-by-two brushes, mounted on a rotating support plate and rotated on themselves in successively inverse directions, with respect to a hypothetical reference fixed point, so as to allow the attack of the burrs of a complex piece from all angles and in all directions, during a linear drive thereof, performed by a conveyor belt on which it is placed. Such a machine is entirely satisfactory, but a finding has been established at the level of metal brushes. Indeed, they must be adjusted accurately in height to avoid excessive wear of the brushes or an alteration of the treated parts while taking into account the wear of said brushes. The measurement means by cutting a photoelectric ray or laser are unreliable due to the irregularity of the surfaces of the brushes and the rapid fouling of the measuring means. In addition, it is tedious to make manual measurements of the diameter of the brushes and relate them to a means for calculating the height of a brush support tray.
Il est également délicat de procéder une mesure précise sur un ensemble de brossage comportant plusieurs brosses. It is also difficult to carry out an accurate measurement on a brushing assembly comprising several brushes.
C'est à ces inconvénients qu'entend plus spécialement remédier la présente invention. Description de l'invention It is to these drawbacks that the present invention is more particularly intended to remedy. Description of the invention
A cet effet, l'invention concernent une machine du type précité, se caractérisant en ce qu'elle comporte des moyens de mesure automatique pour la détection du contact de la surface d'attaque périphérique des brosses avec un plan de référence constitué par le tapis de transport ou la pièce à traiter, de manière à réinitialiser la hauteur desdites brosses par rapport au plan de référence, en fonction de leur degré d'usure, préalablement à une opération d'ébavurage.  For this purpose, the invention relates to a machine of the aforementioned type, characterized in that it comprises automatic measuring means for detecting contact of the peripheral surface of the brushes with a reference plane formed by the carpet transport or the workpiece, so as to reset the height of said brushes relative to the reference plane, according to their degree of wear, prior to a deburring operation.
Sont ainsi réalisés des moyens aptes à assurer automatiquement le calcul du diamètre des brosses relativement à leur usure et, par conséquence, la hauteur du plateau-support de brosses en fonction de l'épaisseur des pièces à traiter. Are thus realized means capable of automatically ensuring the calculation of the diameter of the brushes relative to their wear and, by Consequently, the height of the support tray of brushes according to the thickness of the workpieces.
La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles. The present invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

Brève description des figures Brief description of the figures
La figure 1 représente une vue schématique de l'ensemble de la machine montrant, à l'arrêt, le plateau-support d'entraînement rotatif avec ses brosses et le tapis de transport des pièces à traiter, ainsi que les moyens de détection pour la mesure de la hauteur des brosses selon l'invention.  FIG. 1 represents a schematic view of the entire machine showing, at standstill, the rotary drive support tray with its brushes and the conveyor belt of the parts to be treated, as well as the detection means for the machine. measuring the height of the brushes according to the invention.
La figure 2 représente une vue de dessus de la machine selon la figure 1 .  FIG. 2 represents a view from above of the machine according to FIG. 1.

Les figures 4 et 5 représentent des vues comparatives d'une machine selon la figure 1 , représentant le plateau-support rotatif de brosses, respectivement en position haute de repos et en position basse correspondant à la mise en œuvre des moyens de détection de la mise en contact des brosses sur le plan de référence, en l'occurrence le tapis de transport. Description détaillée FIGS. 4 and 5 represent comparative views of a machine according to FIG. 1, representing the rotating support-plate of brushes, respectively in the high position of rest and in the low position corresponding to the implementation of the detection means of the setting contact brushes on the reference plane, in this case the conveyor belt. detailed description
La machine 1 globalement désignée sur les figures comprend au moins un auto-moteur 2 associé à au moins une brosse métallique 3 et monté sur un plateau-support 4, également entraîné en rotation par un moteur 7 et disposé au-dessus d'un tapis de transport 5 des pièces à traiter 6, pour les entraîner, selon un mouvement linéaire « L », sous le plateau-support rotatif 4 et les mettre en contact avec les brosses métalliques 3, elles-mêmes rotatives, pour l'obtention d'une action de brossage selon de multiples directions.  The machine 1 generally designated in the figures comprises at least one self-motor 2 associated with at least one metal brush 3 and mounted on a support plate 4, also rotated by a motor 7 and disposed above a carpet transport 5 parts 6, to drive them, according to a linear movement "L", under the rotary support plate 4 and put them in contact with the metal brushes 3, themselves rotatable, to obtain a brushing action in multiple directions.
Plus précisément, selon cet exemple de réalisation, le dispositif d'ébavurage comprend huit brosses métalliques cylindriques 3, entraînées individuellement par autant de moteurs correspondants 2 tournants dans des sens successivement inverses droit et gauche, chacune desdites brosses 3, et conséquemment chacun desdits moteurs 2, étant positionnés radialement sur le plateau-support rotatif 4, à équidistance de son centre. More precisely, according to this exemplary embodiment, the deburring device comprises eight cylindrical metal brushes 3, driven individually by as many corresponding motors 2 rotating in successively opposite right and left directions, each of said brushes 3, and consequently each of said motors 2 , being positioned radially on the rotating support plate 4, equidistant from its center.
La pièce à traiter 6 est maintenue sur le tapis 5 par l'intermédiaire d'un plateau magnétique 8. The workpiece 6 is held on the belt 5 by means of a magnetic plate 8.
Selon l'invention, la machine comporte des moyens de mesure automatique pour la détection du contact de la surface d'attaque périphérique des brosses 3 avec un plan de référence « P » constitué par le tapis de transport 5 ou la pièce à traiter 6, de manière à réinitialiser la hauteur desdites brosses 3 par rapport au plan de référence « P », en fonction de leur degré d'usure, préalablement à une opération d'ébavurage. According to the invention, the machine comprises automatic measuring means for detecting the contact of the peripheral driving surface of the brushes 3 with a reference plane "P" consisting of the conveyor belt 5 or the workpiece 6, so as to reset the height of said brushes 3 relative to the reference plane "P", according to their degree of wear, prior to a deburring operation.
Les moyens de détection du contact des brosses 3 sur le plan de référence « P » sont constitués par des roues codeuses embarquées 9, solidaires des arbres 2a des moteurs 2 des brosses 3, ceux-ci n'étant pas alimentés pendant la phase de réinitialisation, donc en roue libre, alors que leur plateau-support 4 est entraîné simultanément en rotation et en descente vers le plan de référence « P », rendu immobile, jusqu'à mise en contact des brosses 3 avec celui-ci, provoquant leur entraînement en rotation, et conséquemment celui des roues codeuses 9, engendrant un signal à transmettre à un automate programmable de la machine donnant un ordre d'arrêt de la descente du plateau 4, cette position correspondant à un point « zéro ». The means for detecting the contact of the brushes 3 on the reference plane "P" consist of embedded coding wheels 9, integral with the shafts 2a of the motors 2 of the brushes 3, these being not fed during the reset phase, thus freewheeling, while their support plate 4 is simultaneously driven in rotation and down to the reference plane "P", rendered stationary, until the brushes 3 come into contact with that here, causing their driving in rotation, and consequently that of the coding wheels 9, generating a signal to be transmitted to a PLC of the machine giving an order to stop the descent of the plate 4, this position corresponding to a point "zero ".
Un capteur 10 de mesure de la hauteur enregistre le point « zéro » donné par les roues codeuses 9 et à partir duquel un ordre de remontée est donné au plateau-support 4 de brosses 3, selon une valeur « e » égale à l'épaisseur « e' » de la pièce 6 à traiter. A height measuring sensor 10 records the "zero" point given by the coding wheels 9 and from which an order of ascent is given to the support tray 4 of brushes 3, according to a value "e" equal to the thickness "E" of the piece 6 to be treated.
La machine est ainsi opérationnelle pour effectuer un ébavurage, tenant compte de l'usure des brosses 3 pour qu'elles ne soient pas trop hautes, tout en ne provoquant pas leur usure excessive en étant trop basses. The machine is thus operational for deburring, taking into account the wear of the brushes 3 so that they are not too high, while not causing excessive wear in being too low.
