Tool for sphere center corrosion correction of spherical part and sphere center corrosion correction method

The invention relates to a spherical part sphere center corrosion correction tool and a sphere center corrosion correction method, and the method comprises the following steps: 1, analyzing the structure of a spherical part, measuring the eccentricity and the eccentricity position of the spherical part, and selecting a proper corrosion solution according to the material of the spherical part; 2, corrosion parameters are calculated; 3, placing the selected corrosion solution in a container with an opening in the upper end, fixing a to-be-corroded part at the part fixing end of a tool in a manner that the corroded and removed part faces downwards, fixing the tool, enabling the lower end of a part mounting arm of the tool to extend into the container, and when a turntable on the tool is located at the uppermost position, rotating the turntable on the tool to rotate; the lower end of the to-be-corroded part is tangent to the liquid level of the corrosion solution; and 4, the corrosion parameters obtained through
