Abstract

L'invention concerne un dispositif de postionnement correct de platines (2), de préférence de traitement dans des presses de formage. Ce dispositif doit renoncer à des stations d'orientation mécaniques coûteuses commandées par des arbres séparés et les éléments d'entraînement et de transmission de mouvement associés comme à des appareils de transfert supplémentaires. Il s'agit également de réduire le nombre de degrés de liberté et de l'accorder à la presse de formage. Une correction de position nécessaire des platines est effectuée jusqu'à trois degrés de liberté à l'aide d'entraînements directs (6). Dans une première conception, au moins un mécanisme planaire à deux coordonnées (3) peut être utilisé de telle façon que le moteur planaire à fonctionnement bidimensionnel, apporte une correction de position de l'élément récepteur des platines respectivement dans la direction X et Y. Lors de l'utilisation de deux moteurs planaires, l'élément récepteur en liaison active avec ces derniers tourne davantage autour de l'axe Z pour le troisième degré de liberté.
