The invention discloses a high-precision curvature regulating method for a mechanical railroad shoe. The method comprises the following steps: a, providing a mechanical railroad shoe by refining; b, installing a regulating mechanism; and c, regulating a curvature of the mechanical railroad shoe. A containing part and a containing groove are opening in the mechanical railroad shoe, and the regulating mechanism is installed inside the containing part and the containing groove, wherein the regulating mechanism comprises a regulating rod, two clamping pieces and two regulating elements. When rotating the regulating elements of the regulating mechanism, the regulating mechanism applies an axial stress onto the mechanical railroad shoe. Due to the fact that the stress is applied onto one side of the mechanical railroad shoe and is not on the central axis of the mechanical railroad shoe, the mechanical railroad shoe is bended to one side under the effect of the moment of force, accordingly the user can operate the regulating elements to regulate the curvature of the mechanical railroad shoe.
