The invention discloses a method for manufacturing a subway vehicle chassis, which mainly comprises the following steps of: 1, a chassis boundary beam I, a plurality of floor profiles and a chassis boundary beam II are assembled and welded to obtain a prefabricated chassis; 2, the prefabricated chassis is taken out of a jig to be adjusted and repaired; 3, the adjusted and repaired prefabricated chassis is in a reverse installation state, a traction bolster and a chassis end beam are assembled and welded, and an intermediate chassis is obtained; 4, the welded intermediate chassis is transferredout of the jig, and flame adjustment and repair are conducted; and 5, the adjusted middle chassis is carried out, and accessories are installed to obtain the subway vehicle chassis. Before parts suchas the traction bolster, the end beam and the like are assembled and welded, the chassis boundary beams and the floor profile are assembled; therefore, the assembly of the chassis boundary beams andthe floor profile can meet two different assembly modes of inserting connection and overlapping connection, the problem that the floor cannot be placed into a mould and assembled after the boundary beams are positioned in the connection mode of the chassis boundary beams and the floor of an inserting connection structure is solved, and the manufacturing period of the chassis is effectively shortened.

    本发明公开了一种地铁车辆底架的制造方法,主要包括:步骤一:将底架边梁Ⅰ、若干个地板型材和底架边梁Ⅱ进行装配、焊接,得到预制底架;步骤二:将预制底架出胎进行调修;步骤三:将调修后的预制底架处于反装状态,装配、焊接牵枕缓和底架端梁,得到中制底架;步骤四:将焊接完成的中制底架调运出胎,进行火焰调修;步骤五:将调修后的中制底架进行加工,安装附件,得到地铁车辆底架;本发明在装配、焊接牵枕缓、端梁等部件前对底架边梁与地板型材装配,使其底架边梁与地板型材的装配能够满足插接和搭接两种不同的装配方式,同时解决了插接结构的底架边梁与地板的连接方式无法在边梁定位之后将地板入胎、装配的问题,有效缩短底架的制造周期。
