[0002] "Non-standard equipment" is non-standard equipment. It is not manufactured in accordance with the unified industry standards and specifications promulgated by the state. Instead, it is designed and manufactured by itself according to its own needs. Its appearance or performance is not included in the national equipment product catalog. When non-standard equipment is produced, welding is involved between components. The welds produced by welding need to be polished. At this time, a polishing machine will be used to process it to improve the smoothness of the equipment.

[0003] In the prior art, Chinese utility model patent publication number CN212044066U discloses a grinder comprising a housing, a grinding wheel, a dust hood, and a fan blade. In use, the grinder requires manual manipulation along the weld seam of a pipe welded part to fully polish the weld. However, this method increases labor intensity and is time-consuming and labor-intensive. Furthermore, the grinder does not adhere well to the weld seam, making it difficult to control the degree of polishing. This often results in over-polishing or incomplete polishing, resulting in a less-than-ideal overall polishing effect.

[0004] To this end, we proposed a non-standard equipment to make weld grinding machine to solve the above disadvantages. Utility Model Content
