Description
La présente invention concerne un dispositif pour mettre en référence,The present invention relates to a device for referencing,
orienter et brider un profilé ou une orient and clamp a profile or a
barre sur centre d'usinage pour des opérations d'usinage du5 type fraisage, détourage, perçage ou sciage sur toutes les faces longitudinales de ces profilés ou barres. bar on machining center for machining operations of the milling, trimming, drilling or sawing type on all the longitudinal faces of these profiles or bars.
Les profilés ou barres peuvent être de différents matériaux métalliques (acier, aluminium,...) ou plastiques The profiles or bars can be of different metallic materials (steel, aluminum, ...) or plastic
ou bois.or wood.
Dans la suite du texte, on utilisera le terme profilé, l'invention est utilisable indifféremment pour usiner des pièces à partir de tous types de profilés de section ouverte, fermée ou barres pleines ou creuses. Dans certaines réalisations, le profilé est bridé pendant l'usinage par des mandrins rotatifs équipés de 2, 3, 4 mors à déplacement et serrage radial autour de l'axe longitudinal du profilé, les opérations d'usinage étant réalisées en l'air sur la partie de profilé qui dépasse des mors ou entre 2 mandrins équipés de tels mors radiaux et qui20 se font face. Ces mandrins sont animés d'un mouvement rotatif autour de l'axe du profilé pour permettre de réaliser des opérations d'usinage tout autour du profilé. Dans cette réalisation, les mandrins sont encombrants et engendrent de nombreuses interférences avec les broches et outils d'usinage. De plus, au fil du temps, avec l'usure des guidages de mors, on constate des phénomènes d'arc-boutement qui affectent le rendement de serrage et induisent des mouvements axiaux du profilé lors du serrage qui sont préjudiciables à la précision.30 Dans d'autres réalisations existantes, le profilé est fixe en rotation et serré dans des étaux, les unités In the following text, the term profile will be used, the invention can be used equally for machining parts from all types of profiles of open, closed section or solid or hollow bars. In certain embodiments, the profile is clamped during machining by rotary mandrels equipped with 2, 3, 4 jaws with displacement and radial tightening around the longitudinal axis of the profile, the machining operations being carried out in the air on the part of the profile which protrudes from the jaws or between 2 mandrels equipped with such radial jaws and which face each other. These mandrels are rotated around the axis of the profile to allow machining operations to be carried out around the profile. In this embodiment, the mandrels are bulky and cause numerous interference with the spindles and machining tools. In addition, over time, with the wear of the jaw guides, there are phenomena of bracing which affect the clamping performance and induce axial movements of the profile during clamping which are detrimental to the precision. In other existing embodiments, the profile is fixed in rotation and clamped in vices, the units
d'usinage étant orientables autour du profilé, les problèmes d'interférence entre outils et dispositifs de bridage restent importants et la conception de la totalité de la35 machine devient très spécifique. Since the machining is orientable around the profile, the problems of interference between tools and clamping devices remain significant and the design of the entire machine becomes very specific.
Le dispositif présenté remédie à la plupart des inconvénients précités, il permet de brider avec précision ! Zg 2779676 le profilé sur ses surfaces de référence, d'usiner les The device presented overcomes most of the aforementioned drawbacks, it allows to clamp with precision! Zg 2779676 the profile on its reference surfaces, to machine the
différentes faces dudit profilé et ce, très près des points de bridage pour éviter les vibrations, tout en évitant les interférences entre outils et système de bridage ou moyens5 de mise en rotation du profilé, du fait du faible encombrement radial du dispositif présenté. different faces of said profile and this, very close to the clamping points to avoid vibrations, while avoiding interference between tools and clamping system or means5 for rotating the profile, due to the small radial size of the device presented.
Le serrage s'effectue sans mouvement parasite ou déformation du profilé même après usure mécanique. Tightening is carried out without parasitic movement or deformation of the profile even after mechanical wear.
Dans le dispositif objet de l'invention, le profilé est serré entre un guide d'appui à la forme de la demi-section référence d'appui du profilé et un demi-mors mobile à la forme de la demi-section opposée, guide fixe et mors mobile ont une largeur à peine supérieure à la largeur du profilé. Plus généralement, plutôt qu'un seul demi-mors15 mobile, on préférera 2 mors mobiles qui brident le profilé suivant 2 axes globalement perpendiculaires, chacun des demi mors étant assujetti à un quart de la section profilé. Le guide d'appui fixe et le ou les mors mobiles sont des pièces facilement interchangeables qui se glissent dans l'alésage cylindrique ou polygonal d'une broche creuse entraînée en rotation pour permettre d'orienter sous différents angles le profilé à usiner. Le guide fixe sert de référence d'appui et est fixé de façon rigide à l'intérieur de ladite broche creuse In the device which is the subject of the invention, the profile is clamped between a support guide in the shape of the half-reference section for supporting the profile and a movable half-jaw in the shape of the opposite half-section, guide fixed and movable jaw have a width barely greater than the width of the profile. More generally, rather than a single movable half-jaw, 2 mobile jaws will be preferred which clamp the profile along 2 generally perpendicular axes, each of the half jaws being subject to a quarter of the profiled section. The fixed support guide and the movable jaw (s) are easily interchangeable parts which slide into the cylindrical or polygonal bore of a hollow spindle driven in rotation to allow the profile to be machined from different angles. The fixed guide serves as a support reference and is rigidly fixed inside said hollow pin
par tous moyens adéquats (vis, clips..). by any suitable means (screws, clips ..).
Des vérins plats de faible course à énergie pneumatique ou éventuellement hydraulique dont le corps fixe est attaché à l'intérieur de l'alésage broche exercent une pression sur chacun des mors mobiles. La mise en pression30 des vérins associés aux mors mobiles immobilise le profilé sur le guide fixe. Une course de quelques dixièmes de millimètres est suffisante pour assurer le bridage. Chacun des vérins sera alimenté de manière indépendante en énergie pneumatique ou hydraulique, ce qui permet des serrages décalés en temps et pression pour les deux directions de serrages perpendiculaires. On peut ainsi plaquer le profilé sur une première face de référence à 2 Flat cylinders of short stroke with pneumatic or possibly hydraulic energy, the fixed body of which is attached to the inside of the spindle bore exert pressure on each of the movable jaws. The pressurization30 of the jacks associated with the movable jaws immobilizes the profile on the fixed guide. A stroke of a few tenths of a millimeter is sufficient to ensure the clamping. Each of the cylinders will be supplied independently with pneumatic or hydraulic energy, which allows tightening offset in time and pressure for the two perpendicular tightening directions. We can thus press the profile on a first face of reference to 2

pression réduite suivant une première direction puis suivant reduced pressure in a first direction then in
l'autre direction à pression normale sur l'autre face de référence pour terminer à pression totale dans les deux directions, bridant ainsi complètement le profilé sur ses5 faces de référence sur le guide. the other direction at normal pressure on the other reference face to finish at full pressure in both directions, thus completely clamping the profile on its 5 reference faces on the guide.
La broche creuse peut tourner à l'intérieur d'un corps fixe autour d'un axe parallèle à l'axe du profilé, sa mise en rotation se faisant par tout moyen connu (poulie- courroie et moteur ou roue-vis tangente et moteur). Le10 profilé bridé entre mors mobiles et guide fixe est ainsi orienté sous différents angles pour l'usinage des différentes faces. Les vérins comportent un joint d'étanchéité à la pression, une butée de fin de course avant non représentée The hollow spindle can rotate inside a fixed body around an axis parallel to the axis of the profile, its rotation being done by any known means (pulley-belt and motor or tangent screw-wheel and motor ). The flanged profile between movable jaws and fixed guide is thus oriented from different angles for the machining of different faces. The jacks have a pressure seal, a front end stop not shown
et des ressorts de rappel ( non figurés) rappelant les vérins vers l'extérieur pression coupée. and return springs (not shown) recalling the cylinders to the outside pressure cut.
Les vérins de bridage liés à la broche tournante sont alimentés en fluide pneumatique ou hydraulique par des joints tournant de conception connue.20 Le système de bridage selon l'invention répond à l'objectif de faible encombrement radial sur toute la périphérie du profilé du fait de la faible épaisseur des The clamping cylinders linked to the rotating spindle are supplied with pneumatic or hydraulic fluid by rotating joints of known design. The clamping system according to the invention meets the objective of small radial size over the entire periphery of the profile because of the thinness of
vérins plats de bridage, d'une largeur de mors à peine supérieure à la largeur du profilé et d'une épaisseur25 minimale du guide fixe et du ou des mors mobiles. flat clamping cylinders, with a jaw width barely greater than the width of the profile and a minimum thickness of the fixed guide and of the movable jaw (s).
Le faible encombrement radial des mors de bridage objet de l'invention sur la périphérie du profilé, permet: - d'utiliser des outils de sciage à disque ce que ne permet généralement pas une machine à mandrin à mors radiaux The small radial size of the clamping jaws object of the invention on the periphery of the profile, allows: - to use disc sawing tools which does not generally allow a machine with a radial jaw chuck
classiques du fait d'interférence entre scie et mandrins. due to interference between saw and chucks.
- de laisser libre les zones de balayage des bras changeur d'outil fraisage, perçage et ainsi limiter les courses de dégagement d'outil lors d'opérations de changement d'outil. - d'approcher, les outils de perçage, fraisage, sciage lors des opérations d'usinage, très prés des mors de serrage, - to leave free the sweeping zones of the milling and drilling tool changer arms and thus limit the tool release strokes during tool change operations. - approach, drilling, milling, sawing tools during machining operations, very close to the clamping jaws,
évitant ainsi les vibrations néfastes pour la qualité. thus avoiding vibrations harmful to quality.
Selon des modes particuliers de réalisation: - l'alésage de la broche creuse qui porte mors fixe et vérins de bridage peut être de différente géométrie According to particular embodiments: - the bore of the hollow spindle which carries the fixed jaw and clamping jacks can be of different geometry
circulaire ou polygonale, carrée par exemple. circular or polygonal, square for example.
- Le dispositif comprend 2 unités identiques qui se font face et les opérations d'usinage sont exécutées sur la - The device includes 2 identical units which face each other and the machining operations are carried out on the
