[0001] The utility model relates to a screw rod production equipment technical field, especially a screw rod polishing wheel device and screw rod polishing machine with adjusting function. BACKGROUND

[0002] Polishing is an essential process in the production process of screw rods. The traditional method is for workers to hold screw rods and polish them against the polishing machine. However, this method usually requires repeated polishing 4-5 times to achieve the desired effect, which is not only time-consuming and labor-intensive, but also harmful to the health of operators in a dusty environment. The nut tooth surface is unevenly polished, and the efficiency is very low.

[0003] Of course, there are also devices that can polish the surface of a rod-shaped object once, such as the rod-shaped object outer surface polishing device disclosed in Chinese Utility Model Patent No. CN202121434614.2. This polishing device is mainly used for polishing and rust removal of the outer surface of rod / tube-shaped workpieces and studs with a helix angle of less than 3 degrees. However, the polishing wheel of the existing polishing device usually does not have adjusting function, and during use, it is difficult to ensure that the tooth profile of the polishing wheel fully and effectively contacts the tooth profile of the screw rod for polishing, which cannot be applied to the polishing needs of multi-head screw rod products with different helix angles. At the same time, it is also unable to compensate for the wear of the polishing wheel, thereby making it difficult to ensure the polishing effect. In view of the above problems, the present inventors have conducted in-depth research on this problem, and thus the present case has been produced. CONTENT OF THE UTILITY MODEL
