The invention discloses a double-decker multiple unit base frame, a base frame assembly position-fixing device and a base frame assembly position-fixing method, and belongs to the technical field of high-speed railway vehicle manufacturing. The double-decker multiple unit base frame comprises two end base frames, two partition walls, a floor for connecting the two partition walls, two edge beams for connecting the two end base frames, and transition connecting structures for connecting the partition walls and the end base frames, wherein one side of each of the transition connecting structuresis fixedly connected to the corresponding end base frame in an inserted manner, and the other side thereof is fixedly connected to the corresponding partition wall in a lap joint manner, so that themodularization of the end base frames and the partition walls is achieved. The base frame assembly position-fixing device comprises a platform, wherein the platform is provided with two supporting mechanisms, two assembling mechanisms, a plurality of supporting and clamping mechanisms, four position-fixing devices capable of forming a rectangle, and supporting and pressing mechanisms for connecting the partition walls and the transition connecting structures. The double-decker multiple unit base frame, the base frame assembly position-fixing device and the base frame assembly position-fixing method have the beneficial effects of reducing the assembling difficulty of the base frame, shortening the manufacturing period of base frame assembly, and improving the production efficiency.
