Disclosed is a device used for rectifying the dynamic balance eccentricity of the compressor-turbine rotor drum component, comprising a balance core shaft; a limit convex ring and thread are arranged on the surface of the balance core shaft; a positioning plate and a locking nut are arranged between the convex ring and the screw segment; a convex circular ring is arranged on the same side where the positioning plate is arranged; the annular surface of the convex circular ring is matched with the grade plate of the compressor which is processed with balance eccentricity rectification; dovetail guide grooves and pressure hook installation holes are alternately arranged on the lateral surface of the convex circular ring with equal arc distance; wherein, a top block and an inclined block are arranged in the dovetail guide groove from up to down; the joint surface of the top block and the inclined block is an inclined plane which constructs an upper slide angle with a horizontal line; a cover plate is arranged on
