[0003] In the prior art, a Chinese patent with announcement number CN213164741U discloses a device for grinding and removing rust from the surface of metal building materials, which adopts a scheme of "including a machine housing, a first gear, a second gear, a grinding disc and a metal tube, a first servo motor on the side wall of the machine housing is connected to a first screw through a motor shaft, the first gear is meshed with the first screw and the second gear on both sides through gear teeth, and the grinding disc embedded in the inner side of the second gear has a circular cross-section, and the two ends of the metal tube are respectively embedded in the grinding disc and the receiving groove, the middle and bottom of the support column embedded in the through hole opened in the support plate 1 on the side wall of the receiving groove are respectively fixedly connected with the support plate 2 and the slide, the slide is slidably connected to the second screw, and the second screw is connected to the second servo motor through the motor shaft". This scheme has the characteristics of uniform polishing and high work efficiency.

[0004] However, the above scheme still has some shortcomings. For example, when the above scheme is actually used, it is fixed by pressing the limit plate against the surface of the tubular building material, and this fixing method causes the surface of the tubular building material to be fixed to be unable to be polished, resulting in a polishing dead angle. At the same time, the inner diameter of the grinding disc used for grinding in the above scheme is fixed and cannot be adjusted according to building materials of different coarsenesses, so that it can only grind tubular building materials of the same coarseness, which has limitations. In view of this, the utility model proposes a polishing and rust removal device for screw production and processing. Utility Model Content
