Abstract

Chaîne de production automatisée (100) et chaîne de production de rotor de moteur. La chaîne de production automatisée comprend une pluralité de plateformes de transfert universelles (200) et des dispositifs d'usinage, et les dispositifs d'usinage sont montés sur les plateformes de transfert universelles ; chaque plateforme de transfert universelle comprend un corps principal de cadre (210) et un mécanisme de transfert et de transport, des éléments de positionnement (250) sont disposés sur le corps principal de cadre, toutes les deux plateformes de transfert universelles adjacentes étant assemblées rapidement dans un ensemble au moyen des éléments de positionnement correspondants ; chaque mécanisme de transfert et de transport peut transporter des pièces (900) au mécanisme de transfert et de transport sur la plateforme de transfert universelle adjacente. Toute la chaîne de production utilise les plateformes de transfert universelles comme bases, différents dispositifs d'usinage sont disposés sur les plateformes de transfert universelles pour former différentes machines individuelles modularisées, et l'assemblage rapide et le réglage flexible de la chaîne de production sont facilités. La chaîne de production de rotor de moteur utilise les plateformes de transfert universelles, de telle sorte que l'usinage automatisé de rotors de moteur peut être amélioré.
