The invention relates to a method for synchronously processing flanges at both ends of a rear axle housing welding assembly, which comprises the following steps: roughly positioning a large hole in the middle of the rear axle housing, and mainly positioning and clamping the flanges at both ends in a V-shape; Then, the spindles at both ends simultaneously drive the end face rough turning tool of the end face flat rotating disc, roughly turning the large end face and the end face of the stop, and leaving axial machining allowance; Then, the spindles at both ends simultaneously drive the end face flat disk to finish turning the large end face and the rabbet end face, so as to ensure the size of the large end face, the size between the rabbet end face and the large section, the roughness and circular runout requirements of the large end face and the verticality requirements between the end face and the excircle axis of the inner hole; Then, the spindles at the rear two ends drive the combined rough turning tool for the excircle of the inner hole to turn the excircle and inner hole of the flange heads at both ends at the same time, leaving machining allowance; Finally, the spindles at both ends simultaneously drive the inner hole excircle combination finishing turning tool to finish turning the outer circle and the inner hole, thus ensuring the coaxiality requirements of flanges at both ends of the rear axle and the coaxiality requirements of inner and outer circles of flanges. Achieve the completion of multiple processes in one clamping.
