The invention belongs to the technical field of airplane structure strength tests, and particularly relates to a main landing gear breaking and separating pin coordinated loading test device. The device comprises an upper loading platform assembly (1) which is supported on a lower supporting platform assembly (7) through a circular column supporting rod (2); the breaking and separating pin switching tool (4) comprises a vertical loading single-lug tool (401) and a double-lug supporting tool (403), a single-lug piece of the vertical loading single-lug tool (401) is connected with a double-lug piece of the double-lug supporting tool (403) through a breaking and separating pin (402), and the double-lug supporting tool (403) is fixed to the lower supporting platform assembly (7); the vertical loading assembly (3) is fixed below the upper loading platform assembly (1), and the bottom of the vertical loading assembly (3) is connected with a vertical loading single-lug tool (401); the horizontal loading assembly (5) is connected to the two ends of the double-lug supporting tool (403) in the axial direction of the breaking pin (402). According to the invention, the loading precision is improved, and the test result is more reliable.
