Only manual grinding can be adopted. The difficulty of manual polishing is adopted: (1) After the elbow, the straight pipe sections on the left side and the right side are longer and are larger than 2000mm, the diameter of the inner hole of the elbow is smaller than 300, and the depth cannot be reached by a common pneumatic polisher. (2) As the angle of the bent pipe becomes smaller, the polishing difficulty increases, and a visual blind area exists in the inner arc area of the bent pipe (as shown in fig. 1 and 4). (3) When the angle of the bent pipe is less than 120 degrees, visual inspection of the bent pipe area is difficult. (4) The polishing tool for the inner hole of the stainless steel elbow has the advantages that the requirement on the surface quality of the inner hole of the elbow is high, the requirement that the uniform wall thickness and the wall thickness difference are controlled within 1mm and the surface roughness is Ra3.2 is met, secondary damage is easily caused to the surface of the elbow during manual operation, the requirement on the surface processing of the inner hole of the stainless steel elbow is difficult to meet, the polishing tool for the inner hole of the stainless steel elbow for small-angle and small-caliber nuclear power has a simple structure in 202221401318.7, is easy to operate, can conveniently polish the inner hole of the stainless steel elbow for small-angle and small-caliber nuclear power, has high inner hole surface quality after processing, is easy to assemble and disassemble and maintain, has good flexibility and adaptability, and is suitable for the inner holes of stainless steel elbows with different bending angles.

However, in patent No. 202221401318.7, since the connecting rod is a rigid member, after extending into the inside of the elbow, the connecting rod can only adapt to a fixed angle, and when the elbows with different angles are processed, the requirement cannot be met, and the applicability is low.
