The invention discloses an omnibearing test device for hidden cracks of fan blades, which comprises a test main body, a first groove is formed in the inner surface wall of one side of the test main body, a flash shell is fixedly arranged in the first groove, and a plurality of flash pulse lamps are fixedly mounted on the outer surface wall of one side of the flash shell. An infrared detector is fixedly arranged in the first groove, a shading mechanism is fixedly arranged between the inner surface walls of the two sides of the testing main body, a repairing mechanism is fixedly connected to the top of the testing main body, and lantern rings are fixedly installed at the positions, close to the four corners, of the top of the repairing mechanism; according to the scheme, the problems that when existing fan blade testing equipment is used for detecting cracks, external interference is not isolated, so that the detection result is possibly inaccurate, and meanwhile, extremely fine implicit cracks cannot be simply
