DISPOSITiF DE BRIDAGE A COMMANDE PNEUMATIQUE, NOTAMMENT
DE MONTAGES D~USINAGEv
L'invention concerne un dispositif de bridage à commande pneumatique notamment de montages d'usinage montés sur un plateau tournant devant un opérateur.PNEUMATIC CONTROL CLAMP DEVICE, IN PARTICULAR
MACHINING ASSEMBLY
The invention relates to a clamping device with pneumatic control including machining fixtures mounted on a turntable in front of an operator.

Dans la plupart des cas les dispositifs de bridage sont actionnés individuellement par des vérins de commande agissant sur un mors de serrage du montage d'usinage. In most cases the clamping devices are actuated individually by control cylinders acting on a clamping jaw of the machining assembly.

Au cours de la rotation du plateau il est souvent prévu d'inclure des arrêts intermédiaires nécessaires et suffisants pour réaliser des opérations automatiques d'usinage ou commandées par un opérateur.During the rotation of the plate it is often planned to include intermediate stops necessary and sufficient to perform automatic machining operations or controlled by an operator.

Ces opérations peuvent n' exiger que des temps d' arrêt très courts insuffisants pour réaliser le bridage, le débridage, le chargement et l'évacuation de la pièce.These operations may require only very short downtimes insufficient to perform the clamping, unclamping, loading and evacuation of the room.

L'invention consiste en l' adaptation sur un plateau tournant d'un distributeur de pression destiné à la commande de bridage et de débridage des montages d' usinage. The invention consists of the adaptation on a turntable of a pressure distributor for the control of clamping and unclamping machining fixtures.

L'invention a plus particulièrement pour oblet un tel distributeur asservi au plateau tournant d' une unité d' usinage dans le but de réaliser la mise sous pression du montage d'usinage qui se présente sous une tête de travail ou la mise hors pression du montage d' usinage qui se présente devant l' opérateur.The invention more particularly for oblet such a slave follower to the turntable of a machining unit in order to achieve the pressurization of the machining assembly which is under a working head or the depressurization of the machining assembly in front of the operator.

L'invention concerne plus particulièrement un dispositif de bridage notamment de montages d' usinage, solidaires d' un plateau tournant sur un pivot devant des modules d'usinage et dans lequel lesdits montages sont mis sous pression ou hors pression à partir d' un système distributeur. The invention relates more particularly to a clamping device in particular of machining fixtures, integral with a turntable on a pivot in front of machining modules and wherein said fixtures are pressurized or depressurized from a system. distributor.

Conformément à l' invention le canal d' alimentation en fluide sous pression débouche dans le pivot porteur d' une série de perçages, de passage du fluide, qui débouchent à la périphérie du pivot au contact d'une chemise tournant conlointement avec le plateau et présentent des orifices radiaux respectivement raccordés aux montages pour former des voies d' admission ou d' échappement en fonction de la position angulaire du plateau par rapport à son pivot.According to the invention, the pressurized fluid supply channel opens into the pivot bearing a series of bores, which pass through the fluid, which open out at the periphery of the pivot in contact with a casing which is rotated in conjunction with the plate and have radial orifices respectively connected to the assemblies to form intake or exhaust paths depending on the angular position of the plate relative to its pivot.

Le dispositif ainsi réalisé augmente le confort du poste de travail par la suppression de l' actionnement obligatoire de commandes manuelles, préalablement à la mise sous pression des montages d' usinage. The device thus produced increases the comfort of the workstation by eliminating the compulsory actuation of manual controls, prior to pressurizing the machining fixtures.

Par voie de conséquence 1' opérateur aura principalement pour tâche d1 effectuer les opérations destinées à obtenir la rotation du plateau ainsi que l' alimentation et l' évacuation des pièces.Consequently, the operator will have the main task of carrying out the operations intended to obtain the rotation of the plate as well as the feeding and evacuation of the pieces.

D' autres caractéristiques et avantages du dispositif ressortiront de la description d' un exemple de réalisation de celui-ci en référence au dessin annexé dans lequel : - la figure I est une vue en plan du plateau utilisant deux modules
d' usinage.Other characteristics and advantages of the device will become apparent from the description of an exemplary embodiment thereof with reference to the appended drawing in which: - Figure I is a plan view of the plate using two modules
machining.

- la figure 2 est une coupe axiale du pivot du plateau et de son système
d' alimentation en fluide sous pression.FIG. 2 is an axial section of the pivot of the plate and its system
supplying fluid under pressure.

- la figure 3 est une vue en perspective du pivot.- Figure 3 is a perspective view of the pivot.

- les figures 4 et 5 sont des vues en coupe horizontales du pivot suivant
les plans 4-4 et 5-5 de la figure 3.- Figures 4 and 5 are horizontal sectional views of the next pivot

Les figures 1 et 2 représentent un plateau 1 constitué par une partie fixe la et une partie mobile lb recevant des montages d'usinage 2, 3, 4 de pièces à usiner par des modules 5, 6. FIGS. 1 and 2 show a plate 1 constituted by a fixed part 1a and a mobile part 1b receiving machining assemblies 2, 3, 4 of workpieces by modules 5, 6.

La partie mobile lb du plateau 1 est montée à rotation sous l' action d'une commande manuelle 7 actionnée par un opérateur 8. Cependant le plateau l pourrait tout aussi bien être mû par un mécanisme d'entraînement actionné par un moteur.The moving part lb of the plate 1 is rotatably mounted by a manual control 7 actuated by an operator 8. However, the plate 1 could just as easily be driven by a drive mechanism actuated by a motor.

Le plateau I porte une chemise 9 centrée et fixée rigidement sur celui-ci au moyen de vis 10.The plate I carries a liner 9 centered and fixed rigidly on it by means of screws 10.

La chemise 9 présente des perçages Il munis de raccords 12 portant les canalisations d' alimentation des montages 2, 3, 4.The liner 9 has bores 11 provided with connectors 12 carrying the supply ducts of the assemblies 2, 3, 4.

Les perçages l l sont montés à défilement sous l'-action de la commande communiquée par l'opérateur 8, devant les perçages correspondants 21 situés à la périphérie du pivot 13 et définissent des voies d'alimentation et d' échappement mieux représentées sur les figures 6 à 8 et résumées ci-après dans un tableau sur lequel les références 32, 33, 34 désignent respectivement les vérins alimentés et mis au repos en fonction de la position angulaire du plateau 1

In order to facilitate the rotation of the plate 1, the pivot 13 is placed on a thrust ball bearing b in order to avoid any abnormal friction with the plate. The pivot 13 is pierced at its center and also forms the supply conduit 16 of the device from a connector 17 and a pipe 18 fixed.

L' ensemble mobile lb du plateau 1 repose sur le bati 20 de la machine par l'intermédiaire d' une butée et de la partie fixe la du plateau. The moving assembly lb of the plate 1 rests on the frame 20 of the machine via a stop and the fixed part of the plate.

Les figures 3 à 5 sont relatives à la structure interne du pivot 13.Figures 3 to 5 relate to the internal structure of the pivot 13.

Le pivot 13 est percé par un canal principal d' admission 23 alimenté par le conduit 16 d' un arbre fixe 15 qui débouche dans la face inférieure 24.The pivot 13 is pierced by a main intake channel 23 fed by the duct 16 of a fixed shaft 15 which opens into the lower face 24.

La face supérieure 25 du pivot porte l' embouchure E d' un canal principal d' échappement 26.The upper face 25 of the pivot carries the mouth E of a main exhaust channel 26.

Les canaux 23, 26 sont disposés longitudinalement et parallèlement l' un à l' autre.The channels 23, 26 are arranged longitudinally and parallel to each other.

Le canal 23 porte des canaux radiaux dérivés 232, 233, 234 qui forment conlointement les voies d' alimentation des vérins 32, 33, 34 des montages 2, 3, 4 Dour en assurer le serrage.The channel 23 carries radial radial channels 232, 233, 234 which together form the feed channels of the cylinders 32, 33, 34 of the assemblies 2, 3, 4 Dour to ensure the clamping.

D' une manière analogue le canal 26 porte des canaux dérivés 262, 263, 264 qui forment conjointement les voies d'échappement des vérins 32, 33, 34 lors de la mise à l'atmosphère des montages 2, 3, 4 pour en assurer le desserrage. In a similar way the channel 26 carries bypass channels 262, 263, 264 which together form the escape routes of the cylinders 32, 33, 34 during the venting of the assemblies 2, 3, 4 to ensure loosening.

Les différents canaux dérivés sont répartis en deux groupes 232, 233, 264 et 262 263 et 234 ainsi que cela est montré aux figures 6 à 8 et sont séparés par des loints d' étanchéité 30.The various derivative channels are divided into two groups 232, 233, 264 and 262 263 and 234 as shown in FIGS. 6 to 8 and are separated by sealing gaskets 30.

A chacun des groupes est associé au moins l'un des canaux 264 ou 234 dérivés à partir des canaux principaux 26 et 23.Each of the groups is associated with at least one of the channels 264 or 234 derived from the main channels 26 and 23.

On voit ainsi qu' à chaque déplacement angulaire du plateau 1 les canaux dérivés 232 - 233 et 234 sont à tour de roule reliés aux 3 vérins 32, 33, 34 de serrage et de desserrage It can thus be seen that at each angular displacement of the plate 1, the derived channels 232-233 and 234 are in turn wheel connected to the three jacks 32, 33, 34 for clamping and loosening.
