The utility model relates to a dynamic balance fixture with decomposed type structure for air compressor-turbo rotor assembly, belonging to a fixture technique, aiming at the problem that the prior fixture generates the runout in the experiment, which comprises a dynamic balance front support point fixture for rotor assembly sleeved on the front shaft neck of the air compressor, a dynamic balance rear support point fixture for rotor assembly sleeved on the turbo rear shaft neck, and a dynamic radial eccentric mechanism for correcting rotor assembly, wherein the dynamic balance front support point fixture for rotor assembly is composed of a driving disc, a connection shaft and a location shaft which are connected in order. The dynamic balance rear support fixture for rotor assembly is a tubular rear shaft sleeve. An annular inner flange is arranged at the middle of inner wall. The dynamic balance radial eccentric mechanism for correcting rotor assembly comprises a balance core shaft, a location disc is arrange
