Description

一种汽车两侧车门的同步装配工装 技术领域
本发明涉及汽车装配技术领域，具体涉及一种汽车两侧车门的同步装配工装。
 背景技术
目前，在汽车制作过程中，车门需要多种器具分别完成存放、转运、装配等，如车门在装配时，在装配车间内需要通过专用的转运器具转运至门分装区域，并需要人工搬运至装配器具上进行装配。因此，装配一个车门总成，需要使用多种工位器具，需要人工搬运车门在不同工位器具之间转移，导致装配效率低，员工劳动强度大；而且，车型不同，车门结构也不同，由于各车型间的工位器具不能通用，造成每种车型都要大量制作工位器具，造成车间存储面积的大量占用， 以及资源的严重浪费，还容易造成工位器具管理的混乱，同时一般的车门装配都是逐个进行的，不能同步对两侧车门进行装配。
 技术问题
