Description

MACHINE-OUTIL MUNIE D'UN DISPOSITIF DE PREPARATION AU BRIDAGE EN TEMPS MASQUE. UTILISANT DES VENTOUSES DOUBLE FACE MACHINE TOOL PROVIDED WITH A MASKING TIME CLAMPING PREPARATION DEVICE USING DOUBLE-SIDED CUPS
La présente invention concerne une machine-outil munie d'un dispositif de préparation au bridage en temps masqué, utilisant des ventouses double face.The present invention relates to a machine tool provided with a device for preparing for clamping in masked time, using double-sided suction cups.
Sur les machines-outils à commande numérique destinées principalement à l'usinage des plans de cuisine et de salle de bains, les pièces à usiner sont habituellement bridées au moyen de ventouses double face. Celles-ci sont disposées entre le dessous de la pièce à usiner et le dessus de la table de la machine-outil, et sont généralement en nombre important de manière à immobiliser parfaitement la pièce lors de son usinage, pour avoir une bonne qualité de travail.On numerically controlled machine tools intended mainly for the machining of kitchen and bathroom surfaces, the workpieces are usually flanged by means of double-sided suction cups. These are arranged between the underside of the workpiece and the top of the table of the machine tool, and are generally large in order to perfectly immobilize the workpiece during its machining, to have a good quality of work .
Ces ventouses, par un système de dépression, permettent la fixation de la pièce de manière à ce que la machine-outil puisse évoluer sur les quatre côtés et la face supérieure de la pièce à travailler, sans que l'opérateur risque de collision avec le dispositif de bridage.These suction cups, by a vacuum system, allow the attachment of the workpiece so that the machine tool can evolve on all four sides and the upper face of the workpiece, without the operator risk of collision with the clamping device.
La mise en place de ces ventouses avant l'usinage de la pièce se fait généralement manuellement ou de façon semi-automatique avec la broche de la machine sur sa propre table, c'est-à-dire lorsque la machine est à l'arrêt. Par ailleurs, l'opérateur doit choisir la position des ventouses de bridage en fonction des usinages à effectuer. La mise en place de ces ventouses et de la pièce à usiner représente une perte de temps, et par conséquent une augmentation du prix de revient de la pièce. L'invention se propose de remédier aux inconvénients précités en proposant une machine-outil permettant en parallèle l'usinage d'une pièce et la mise en place de ventouses ainsi qu'une autre pièce, sur une table annexe. Des ventouses équipées de billes porteuses escamotables permettent le transfert de la prochaine pièce à travailler sous la machine afin d'éviter tout arrêt prolongé de celle-ci. A cet effet, la présente invention a pour objet une machine-outil constituée d'une table de travail, caractérisée en ce qu'elle est munie d'une table de préparation, attenante à ladite table de travail, destinée à la mise en place des ventouses de bridage pour une pièce à usiner, parallèlement à l'usinage en cours sur une autre pièce.The placement of these suction cups before machining the workpiece is usually done manually or semiautomatically with the spindle of the machine on its own table, that is to say when the machine is stopped . In addition, the operator must choose the position of the clamping suction cups according to the machining to be performed. The placement of these suction cups and the workpiece represents a waste of time, and therefore an increase in the cost price of the part. The invention proposes to overcome the aforementioned drawbacks by proposing a machine tool allowing in parallel the machining of a workpiece and the placement of suckers and another workpiece, on a side table. Suction cups equipped with retractable bearing balls allow the transfer of the next piece to work under the machine to avoid any prolonged stop of this one. For this purpose, the present invention relates to a machine tool consisting of a work table, characterized in that it is provided with a preparation table, adjacent to said work table, for the implementation clamping suction cups for a workpiece, parallel to machining in progress on another workpiece.
On comprendra mieux l'invention en référence aux dessins annexés sur lesquels : la figure 1 est une représentation de la machine-outil sur laquelle peuvent être utilisées les ventouses selon l'invention, - la figure 2 est une représentation de la ventouse en position de transfert, la figure 3 est une représentation de la ventouse en position de bridage, la figure 4 est une représentation de la ventouse lors de son bridage avec le dessous de la pièce à usiner.The invention will be better understood with reference to the accompanying drawings, in which: FIG. 1 is a representation of the machine tool on which the suction cups according to the invention may be used; FIG. 2 is a representation of the suction cup in the position of Figure 3 is a representation of the suction cup in the clamping position, Figure 4 is a representation of the suction cup during its clamping with the underside of the workpiece.
La machine-outil 1 selon l'invention est constituée d'une table de travail 1a sur laquelle une pièce 4 est usinée. Une seconde table 1b, destinée à la préparation de la pièce 4, est disposée dans la continuité de la table de travail 1 a. La table de préparation 1 b est destinée à la mise en place des ventouses de bridage. Ces dernières sont des ventouses double face, permettant un bridage de la pièce sur la table.The machine tool 1 according to the invention consists of a work table 1a on which a workpiece 4 is machined. A second table 1b, for the preparation of the part 4, is arranged in the continuity of the work table 1a. The preparation table 1b is intended for the placement of the clamping suction cups. These are double-sided suction cups, allowing a clamping of the room on the table.
La mise en place des ventouses est réalisée par leur positionnement préalable sur la table de préparation 1b. Une dépression envoyée dans la ventouse de bridage 2 permet la liaison de la ventouse avec le dessous de la pièce 4. Un second type de ventouses 3, destinées particulièrement au transfert de la pièce 4, est également liée à la pièce 4 à usiner. La réalisation du bridage sera expliquée dans la suite de la description. L'installation des ventouses 2 et 3 est réalisée indépendamment du fonctionnement de la machine-outil 1 , ce qui permet à la fois la préparation d'une pièce, tandis qu'une autre pièce est en cours d'usinage.Placing of the suction cups is achieved by their prior positioning on the preparation table 1b. A vacuum sent into the clamping cup 2 allows the connection of the suction pad with the underside of the workpiece 4. A second type of suction cups 3, particularly for the transfer of the workpiece 4, is also connected to the workpiece 4 to be machined. The completion of the clamping will be explained in the following description. The installation of the suction cups 2 and 3 is performed independently of the operation of the machine tool 1, which allows both the preparation of a part, while another part is being machined.
Une fois la mise en place des ventouses de bridage 2 et de transfert 3 réalisée, la pièce 4 à usiner, disposée préalablement sur la table de préparation 1 b, est transférée jusqu'à la table de travail 1a de la machine-outil. Le bridage de la pièce 4 avec les ventouses 2 et 3 est maintenu lors du transfert. La liaison de la pièce 4 avec la table 1a est ensuite réalisée par envoi d'une dépression dans le corps d'alimentation 3d des ventouses. La pièce 4 est alors prête à être usinée. La création d'une pression ou d'une dépression dans les ventouses 2 et 3 est réalisée par des moyens classiques qui ne font pas l'objet de la présente invention, et ne seront donc pas plus détaillés.Once the establishment of the clamping cups 2 and transfer 3 made, the workpiece 4 to be machined, previously disposed on the preparation table 1b, is transferred to the work table 1a of the machine tool. Clamping the part 4 with the suction cups 2 and 3 is maintained during the transfer. The connection of the part 4 with the table 1a is then achieved by sending a vacuum in the feed body 3d suckers. The piece 4 is then ready to be machined. The creation of a pressure or a vacuum in the suction cups 2 and 3 is achieved by conventional means which are not the subject of the present invention, and therefore will not be more detailed.
La ventouse de bridage 2 est une ventouse double face, permettant ainsi sa liaison à la fois avec le dessous de la pièce 4 au niveau de sa face supérieure, tandis que sa face inférieure permet le bridage avec la table de travail 1a.The clamping suction cup 2 is a double-sided suction cup, thus allowing its connection to both the underside of the part 4 at its upper face, while its lower face allows the clamping with the work table 1a.
La ventouse de bridage/transfert 3 est également double face de manière à assurer une liaison avec la face inférieure de la pièce 4 au niveau de sa face supérieure. Sa face inférieure permet quant à elle soit le bridage avec les tables 1a ou 1b, soit le transfert de la table de préparation 1b vers la table de travail 1a.The clamping clamp / transfer 3 is also double-sided so as to provide a connection with the underside of the part 4 at its upper face. Its lower face allows for it to be clamping with the tables 1a or 1b, or the transfer of the preparation table 1b to the work table 1a.
La ventouse 3 est constituée d'un corps 3a, dont la forme est de préférence cylindrique. Toute autre forme appropriée pourra également être utilisée. La face supérieure 3b de la ventouse 3 comprend une ventouse à lèvre, destinée à son contact avec le dessous de la pièce 4 à usiner. Sa face inférieure 3c est munie d'un joint torique pour sa liaison avec les tables de travail 1a ou de préparation 1a.The suction cup 3 consists of a body 3a, whose shape is preferably cylindrical. Any other suitable form may also be used. The upper face 3b of the suction cup 3 comprises a lip suction cup, intended for its contact with the underside of the workpiece 4 to be machined. Its underside 3c is provided with an O-ring for its connection with the work tables 1a or preparation 1a.
La ventouse de bridage/transfert 3 présente également deux alimentations 3d et 3d' destinées à mettre sous pression ou dépression respectivement la face inférieure 3c et la face supérieure 3b de la ventouse 3, assurant ainsi respectivement le transfert ou le bridage.The clamping clamp / transfer 3 also has two feeds 3d and 3d 'intended to pressurize or depression respectively the lower face 3c and the upper face 3b of the suction cup 3, thus ensuring respectively the transfer or clamping.
Le corps 3a de la ventouse 3 est constitué d'un piston 3 g dont la partie inférieure comprend une bille porteuse 3h. Le mouvement du piston 3g est limité par un circlips (non représenté) ; il est réalisé par coulissement dans son logement et permet à la bille porteuse 3h d'être en retrait ou en contact avec les tables 1a ou 1b, permettant ainsi sa liaison ou non. La bille 3h en position sortie dépasse de la face inférieure 3c de la face inférieure 3c de la ventouse 3.The body 3a of the suction cup 3 consists of a piston 3 g whose lower part comprises a carrier ball 3h. The movement of the piston 3g is limited by a circlip (not shown); it is made by sliding in its housing and allows the carrier ball 3h to be recessed or in contact with the tables 1a or 1b, thus allowing its connection or not. The ball 3h in the extended position protrudes from the lower face 3c of the lower face 3c of the suction cup 3.
L'alimentation 3d de la face inférieure 3c de la ventouse 3 présente un clapet anti-retour 3f destiné soit à actionner le piston 3g dans le cas d'une pression qui engendre la sortie de la bile porteuse 3h, soit à assurer le bridage entre la face inférieure 3c et les tables 1a ou 1b dans le cas d'une dépression.The supply 3d of the lower face 3c of the suction cup 3 has a check valve 3f intended either to actuate the piston 3g in the case of a pressure that causes the exit of the carrier bile 3h, or to ensure the clamping between the lower face 3c and 1a or 1b tables in the case of a depression.
Une dépression créée sur la face supérieure 3b de la ventouse 3 permet sa liaison par bridage avec la pièce 4 à usiner, tandis qu'une dépression sur la face inférieure 3c permet d'obtenir son bridage avec les tables 1a ou 1b.A depression created on the upper face 3b of the suction cup 3 allows its connection by clamping with the workpiece 4 to be machined, while a depression on the lower face 3c makes it possible to obtain its clamping with the tables 1a or 1b.
La double dépression exercée sur la ventouse 3, par les systèmes d'alimentation 3d et 3d', permet d'assurer un double bridage de la ventouse 3 sur les tables 1 a ou 1 b et sous la pièce 4 à usiner.The double depression exerted on the suction cup 3, by the feeding systems 3d and 3d ', makes it possible to ensure a double clamping of the suction cup 3 on the tables 1a or 1b and under the workpiece 4 to be machined.
Lorsque la dépression est créée sur sa face inférieure 3c grâce au système d'alimentation 3d, la ventouse 3 est bridée au niveau de la table 1a ouWhen the depression is created on its underside 3c with the 3d feeding system, the suction cup 3 is clamped at the table 1a or
1 b. Le piston 3g remonte dans son logement, entraînant la bille porteuse 3h avec lui. De ce fait, la bille 3h n'est plus en contact avec la table 1a ou 1b ; elle est en position escamotée, permettant ainsi la liaison de la ventouse 3 avec la table 1a ou 1 b. Une dépression grâce au système d'alimentation 3d' sur la face supérieure de la ventouse 3 lui permet de brider la pièce 4 à usiner, sur sa face inférieure 3c.1 b. The piston 3g goes up in its housing, driving the ball carrier 3h with him. As a result, the ball 3h is no longer in contact with the table 1a or 1b; it is in the retracted position, thus allowing the connection of the suction cup 3 with the table 1a or 1b. A depression thanks to the feeding system 3d 'on the upper face of the suction cup 3 allows it to clamp the workpiece 4 to be machined on its underside 3c.
Pour assurer le transfert de la pièce 4 de la table de préparation 1b vers la table de travail 1a, une pression est envoyée dans le système d'alimentation 3d de la ventouse 3. Cette pression ne se dirige pas vers la face inférieure 3c grâce au clapet anti-retour 3f, mais va vers la partie supérieure du piston 3g.To ensure the transfer of the part 4 of the preparation table 1b to the work table 1a, a pressure is sent into the supply system 3d of the suction cup 3. This pressure does not go to the lower face 3c thanks to 3f check valve, but goes to the top of the piston 3g.
Ainsi, le piston 3g descend dans son logement, et permet de faire sortir la bille porteuse 3h du corps 3a de la ventouse 3. Cette dernière sera ainsi en contact avec la table de préparation 1b. La bille 3h est alors en position sortie, ce qui permet de décoller la ventouse 3 par rapport à la table de préparation 1b. La pièce 4, bridée simplement avec les ventouses de type 2 et 3, peut alors être transférée vers la table de travail 1a par roulement de la bille porteuse 3h.Thus, the piston 3g goes down into its housing, and allows the carrier ball 3h out of the body 3a of the suction cup 3. The latter will thus be in contact with the preparation table 1b. The ball 3h is then in the extended position, which allows to take off the suction cup 3 relative to the preparation table 1b. The part 4, clamped simply with the suction cups of type 2 and 3, can then be transferred to the work table 1a by rolling the carrier ball 3h.
Après transfert, il reste simplement à injecter une dépression dans les ventouses de type 2 et 3 dans le système d'alimentation 3d pour assurer le bridage de la pièce 4 avec la table de travail 1a, pour que ladite pièce puisse être usinée.After transfer, it is simply to inject a vacuum in the type 2 and 3 suction cups into the feed system 3d to clamp the workpiece 4 with the work table 1a, so that said workpiece can be machined.
Comme il ressort de la description, la présence de deux tables, l'une destinée à la préparation de la pièce à usiner et l'autre à l'usinage proprement dit, permet un gain de temps important, correspondant à la mise en place des ventouses et de la pièce. Ce gain de temps est optimisé également par le transfert de la pièce à usiner directement avec ses ventouses.As is apparent from the description, the presence of two tables, one for the preparation of the workpiece and the other for clean machining said, saves a lot of time, corresponding to the placement of the suction cups and the room. This saving of time is also optimized by transferring the workpiece directly with its suction cups.
Bien que l'invention ait été décrite avec des moyens de réalisation particuliers, elle comprend tous les équivalents techniques des moyens décrits. Although the invention has been described with particular embodiments, it includes all the technical equivalents of the means described.
