The utility model discloses a coil press-fitting tool for an amorphous alloy three-phase stereoscopic transformer. The coil press-fitting tool comprises an upper press plate in a Y shape, a lower press plate in a Y shape, a tensioning threaded rod and a nut, wherein the tensioning threaded rod is connected to the center of the upper press plate and the center of the lower press plate, and the nut is in threaded connection with the tensioning threaded rod. The external surfaces of three supporting plates of the upper press plate are respectively provided with a threaded hole, a back pressure threaded rod is in threaded connection with the threaded hole in each supporting plate, the upper press plate and the lower press plate are located at the upper ends and the lower ends of coils in a one-to-one corresponding mode, the tensioning threaded rod compresses the upper press plate and the lower press plate on the coils by adjusting the nut, and the lower ends of the back pressure threaded rods are pressed on the upper end faces of the corresponding coils in an abutting-against mode by adjusting the back pressure threaded rods. The coil press-fitting tool can ensure that the three coils of the transformer can be compressed and ensure the product quality.
