The invention is suitable for the field of train chassis manufacturing, and provides a rail transit city domain train chassis manufacturing process. A floor, chassis boundary beams, end beams, a traction and buffering assembly and accessories in a city domain train chassis structure are machined and synthesized through the following technological steps that plate and beam synthesis is synchronously completed, and after coupler seat synthesis, the traction and buffering assembly is synthesized and machined, and the end beams are machined; the plate-beam combination comprises the steps of integrally welding and combining a chassis boundary beam and a floor after the chassis boundary beam is processed; then directly synthesizing the reverse installation of the chassis on the chassis synthesizing tool; then entering a machining center to complete chassis machining; and then transferring to a chassis accessory station to complete the installation of accessories. Therefore, according to the process, the normal assembly and synthesis process of the chassis is canceled, the station and personnel configuration is reduced, the part transferring and overturning time is shortened, the production efficiency is improved, and the manufacturing cost is reduced.

    本发明适用于列车底架制造领域,提供了一种轨道交通市域列车底架制造工艺,通过以下工艺步骤对市域列车底架结构中的地板、底架边梁、端梁、牵缓组成以及附件进行加工合成:同步完成板梁合成、车钩座合成后进行牵缓组成的合成和加工、端梁加工的步骤:板梁合成包括底架边梁加工完成后与地板整体焊接合成并加工;随后在底架合成工装上直接进行底架反装的合成;随后进入加工中心完成底架加工;随后转入底架附件工位完成附件的安装。借此,本工艺取消底架正装合成工序,减少了工位和人员配置,减少了部件转运和翻转时间,提高了生产效率,降低了制造成本。
