Description

Technical Field

[0001] The invention relates to the technical field of grinding waste cleaning devices, in particular to a universal grinder for cleaning attached matter on the welding surface of a steel casting. Background Art

[0002] Before welding steel castings, the parts need to go through a series of treatment steps to ensure that the coating can be firmly attached to the surface of the parts and to improve the quality and durability of the coating.

[0003] After welding, the steel castings need to be cleaned first to remove the scraps on the surface of the steel castings and the residues at the welding points, and then spray-painted to reduce the chance of rust and desoldering of the steel castings. In order to make the coating adhere better to the surface of the parts, it is sometimes necessary to make the surface of the parts have a certain degree of roughness, which is achieved through surface grinding, polishing and other process methods.

[0004] At present, most of the conventional cleaning methods use suction to absorb the scraps on the surface of steel castings. However, when cleaning the metal scraps on steel castings, it is difficult to clean the scraps on the surface of steel castings and the residues at the welding points, which will affect the effect of the later painting. Therefore, surface grinding and polishing operations are required. Conventional grinding machine equipment has a poor application range, and the adjustment and shifting operations of steel castings are complicated and inefficient.
