The invention discloses an auxiliary device for assembling a transmission frame assembly, comprising a rotating mechanism for positioning and installing a casing and driving the casing to rotate in the circumferential direction, a turning mechanism for installing the rotating mechanism and driving the rotating mechanism and the casing to turn up and down, A support base for erecting a turning mechanism and a measuring mechanism mounted on the support base for measuring the gear gap between the second helical gear shaft and the first helical gear shaft. The auxiliary device for assembling the transmission frame assembly of the present invention drives the casing to rotate in the circumferential direction through the rotating mechanism, so as to assemble the different areas of the mounting surface facing upwards of the casing, and drives the rotating mechanism and the casing to turn up and down through the overturning mechanism, so as to turn the casing up and down. The different mounting surfaces of the casing are turned to face upwards for assembly. After assembly, the measuring mechanism installed on the support base is used to measure whether the gear gap between the second helical gear shaft and the first helical gear shaft meets the assembly accuracy requirements and meets the transmission frame. Operational requirements in the assembly process of components.
