The invention belongs to the field of aero-engine blade machining, and particularly relates to a method for reconstructing a hollow adjustable blade grinding machining model based on blue light detection. According to the technical scheme, the reconstruction method for the hollow adjustable blade grinding machining model based on blue light detection comprises the steps that firstly, nondestructive testing is conducted on the wall thickness of a hollow adjustable blade; then hollow adjustable blade outline scanning based on blue light detection is carried out; then, according to the outline and wall thickness data, an actual workpiece model with the outline and a cavity structure is reconstructed; and finally, the actual workpiece model and the hollow adjustable blade theoretical model are subjected to registration, grinding allowance is reasonably distributed to construct a new outer surface profile, and a hollow adjustable blade grinding machining model is reconstructed according to the new outer surface pr
