[0002] Construction projects refer to the construction of various buildings and structures. This investment requires the mobilization of materials and construction activities. During the manufacturing of construction machinery, various tubular and plate-shaped workpieces require grinding and rust removal. Low-carbon steel pipes are a common type of tubular material used in machinery manufacturing.

[0003] At present, when performing grinding and rust removal processing on cylindrical low-carbon steel pipes, it is necessary to grind the inner and outer walls of the pipe fittings to meet the needs of mechanical manufacturing and processing. When grinding the inner wall of the pipe fittings, for pipe fittings with larger diameters, workers are generally required to enter the pipe to grind. In this way, during the grinding process, due to the relatively closed and narrow internal space of the pipe fittings, it will have the defect of great difficulty in grinding. For pipe fittings with smaller diameters, a rod is generally used to fix the grinding head, and then the rod is used to place the grinding head on the inner wall of the pipe fitting for grinding. In this way, during the grinding process, the grinding depth is limited by the length of the rod, and it is difficult to grind deep inside the inner cavity of the pipe fitting, and the adaptability is limited.
