The invention relates to a hanger shaft structure capable of reducing deformation of a tank wall of an oil tank and a machining method, in particular to the technical field of hanger shaft structures of oil tanks of power transformers. According to the hanger shaft structure capable of reducing deformation of the tank wall of the oil tank, a fixing plate and the tank wall are welded, and the connecting mode that a thick-wall pipe and the tank wall are directly welded in a traditional structure is improved; the input of welding heat is reduced, the deformation amount of the box wall is further reduced, meanwhile, the thick-wall pipe or the round steel retracts into the inner surface of the fixing plate by 2-5 mm when the inner side of the fixing plate is welded, so that the surface, within the coverage range of the fixing plate, of the box wall has a free telescopic space in the welding process of the box wall, and dead bending deformation is reduced; according to the hanger shaft structure capable of reducing the deformation of the tank wall of the oil tank, the welding groove angle alpha and the welding groove angle beta are arranged at the bottom of the fixing plate, and in the welding process, by means of a layered welding mode, the qualified rate of welding is increased, the phenomenon of insufficient welding of a welding seam is avoided, and the stability of the connecting structure of the hanger shaft and the tank wall is guaranteed.

    本发明涉及一种降低油箱箱壁变形的吊轴结构及加工方法,具体涉及电力变压器油箱吊轴结构技术领域,该降低油箱箱壁变形的吊轴结构,通过将固定板与箱壁进行焊接,改进了传统结构中厚壁管与箱壁直接焊接的连接方式,减少了焊接热量的输入,进而使得箱壁变形量减少,同时通过固定板内侧焊接时厚壁管或圆钢缩进固定板内表面2‑5mm,使得箱壁在焊接过程中,箱壁在固定板覆盖范围内的表面具有自由伸缩的空间,减少死弯变形;该降低油箱箱壁变形的吊轴结构,通过在固定板底部设置有焊接坡口角度α和角度β,在焊接的过程中,通过分层焊接的方式,进而提高了焊接的合格率,避免出现焊缝虚焊的现象,保证了吊轴与箱壁连接结构的稳定性。
