[0002] After long-term use, the surface of the screw and other shaft parts is easily oxidized and rusted, which affects its working effect, so it must be rusted regularly. Traditionally, manual rust removal is used, and the screw is polished by hand with sandpaper (one hand holds the screw and the other hand polishes with sandpaper). The open operation has an incomplete polishing effect. Manual polishing can easily cause the screw to collide, affecting the accuracy; manual operation has poor accuracy and is prone to over-grinding; the screw is generally heavy, the operation intensity is high, the daily production capacity is low, and the efficiency is low.

[0003] In order to solve the above problems, for example, Chinese patent document 202320388965.7 discloses a steel pipe laser cutting and polishing integrated machine, which relates to the technical field of steel pipe processing devices, including a base; a slide, which slides and cooperates with the top of the base along the X-axis direction; a fixed seat, which is arranged at one end of the slide; a first clamping mechanism for clamping the steel pipe, which is arranged at the fixed seat; a laser cutting mechanism for cutting the steel pipe, which is arranged at the fixed seat; a sliding seat, which is slidably arranged at the other end of the slide to approach or move away from the fixed seat; a second clamping mechanism for clamping the steel pipe, which is arranged at the sliding seat; a polishing mechanism for polishing the inner wall of the steel pipe, which is arranged at the slide and located between the fixed seat and the sliding seat, and the polishing mechanism has two polishing wheels extending in opposite directions, and the two polishing wheels are driven by a power device to achieve synchronous movement along the three directions of the X-axis, the Y-axis and the Z-axis. It has a compact structure, improves production efficiency and reduces polishing wheel grinding wheels.

[0004] In the above technical solution, although the polishing effect on the surface of the steel pipe is achieved under certain circumstances, its structure is relatively complex, the operation is cumbersome, the work efficiency is low, the cost is high, and it still needs to be improved for the need of rust removal only.
