The invention discloses a rear overhang constant volume machine for a vehicle body assembly line. The machine comprises: an underframe, which is arranged on the vehicle body assembly line; a synchronizing mechanism, which is arranged on the underframe and used for synchronous connection with or separation from an FDS line body synchronized block, and can enable the underframe to move synchronouslywith the synchronized block; an anti-floating mechanism, which is arranged on the underframe and used for tensioning or loosening the vehicle body; a press-fitting mechanism, which is arranged on theunderframe and used for press-fitting a rear overhang spring to a spring preassembling position; a tightening mechanism, which is arranged on the anti-floating mechanism and used for tightening locking bolts; and a control system, which is connected to the synchronizing mechanism, the anti-floating mechanism, the press-fitting mechanism and the tightening mechanism respectively and used for controlling the working states of all the components. The rear overhang constant volume machine is high in synchronism and suitable for different vehicle types; and under the action of the anti-floating mechanism, the vehicle body can be prevented from being jacked up or toppled over, rapid assembly of the rear overhang spring is facilitated, meanwhile, tightening and carrying are separated, the circulation process time is shortened, and the assembly efficiency and productivity are improved.

    本发明公开了一种用于车体装配线的后悬定积机,包括底架,设置于车体装配线上;同步机构,设置于底架上用于与FDS线体同步块同步连接或分离,底架能够通过同步机构与同步块同步运动;防浮起机构,设置于底架上用于拉紧或松开车体;压装机构,设置于底架上用于将后悬弹簧压装至弹簧预装位置;拧紧机构,设置于防浮起机构上用于拧紧锁紧螺栓;控制系统,控制系统分别与同步机构、防浮起机构、压装机构和拧紧机构连接,用于控制各部件的工作状态。本发明的后悬定积机,其同步性高,适用于不同车型;在防浮起机构作用下,可防止车体顶起或倾倒,利于后悬弹簧快速装配,同时将拧紧与搭载分开,缩短循环过程时间,提升装配效率和产能。
