| description | The invention relates to a steam turbine rotor journal scratch polishing device comprising upper and lower semicircular assemblies. Each semicircular assembly comprises a shell and a grinding frame, and a plurality of rotating handles are arranged on the shells; grinding blocks located between axial partition plates are installed in the grinding frame at intervals, and a grinding sand cavity is formed between every two adjacent grinding blocks; and sand supplementing openings corresponding to the grinding sand cavities are formed in the shells, and sand supplementing devices are installed at the sand supplementing openings. According to the polishing device, through arrangement of the semi-cylindrical shells and the grinding frame, grinding block mounting cavities and the grinding sand cavities are arranged at intervals and formed between the axial partition plates of the grinding frame, and the grinding blocks located between the two axial partition plates are mounted in the grinding block mounting cavities; |
