摘　　要：介绍了SS7C(三段桥)机车底架组对工艺装备的设计方法,按照设计图纸技术要求和“车体商品化”质量标准,提出控制底架旁弯≤4mm、侧梁垂直度≤2mm,牵引杆座及二系弹簧支座精确定位的措施,以及焊缝横向、纵向收缩对底架定位的影响。The design methods of processing equipment for SS7C （three-section-brldge） locomotive chassis constitution are introduced. In accordance with the drawing technical requirement and car body commoditization quality standard, proposes the controlling method for chassis underframe, sidewise bending ≤4 mm, verticality ≤2 mm, and precisely positioning measures of drive shaft seat and secondary spring support, the impacts of transverse and longitudinal shrinkage of welding seam on underframe positioning.
