A型货运电力机车是我国目前单轴功率最大的重载货运电力机车.对于其底架钢结构的组对和焊接,难点在于保证边梁上四个旁承座内表面的平面度(边梁容易产生很大的焊接变形);重点在于变压器梁的定位.为此设计并制造了专用组焊工装,其基本结构包括平台框架,端部、边梁旁承、变压器梁支撑装配,侧向顶紧装置,纵向移动装置,油缸总成以及各种定位装置和测量装置.该组焊工装安全可靠,可完成底架钢结构主要结构部件的组对与焊接,且满足设计图纸中的各项技术要求.
A type freight electric locomotive is currently the largest uniaxial power heavy-duty freight electric locomotive in China.For the pair and welding of the chassis steel structure, the difficulty is to ensure the flatness of the inner surface of the four side seats on the side beam (side beam Easy to produce a great welding deformation); focus on the positioning of the transformer beam.To this end, the design and manufacture of a special welding equipment, the basic structure, including the platform frame, the end, side beam bearing, transformer beam support assembly, lateral roof Tightening device, vertical moving device, cylinder assembly and various positioning devices and measuring devices.The set of welders is safe and reliable, can complete the assembly and welding of the main structural components of the chassis steel structure, and meet the technical requirements of the design drawings Claim.
