Description

Technical Field

[0001] The utility model relates to the technical field of electroplating rack coating polishing devices, in particular to a coating polishing device for an automobile accessory electroplating rack. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation, improve wear resistance, reflectivity, corrosion resistance and enhance aesthetics.

[0003] When auto parts manufacturers treat the surface of metal castings, most of them use automatic electroplating production lines. Automatic electroplating production lines are mainly composed of electroplating devices, circulation lines and hangers. The castings to be treated are hung on the hangers, which are hung on the circulation lines and run along the circulation lines to the electroplating devices for electroplating. After the electroplating is completed, the hangers and castings return to their original places along the circulation lines, and the operator takes down the finished products after electroplating.

[0004] After the hanger enters the electroplating tank, it needs to be immersed in the electroplating solution along with the casting, and a coating will also form on the hanger, causing the hanger to be non-conductive. Therefore, when working again, the coating on the hanger that contacts the casting needs to be polished off.

[0005] For example, the public document with application number 20202077779.X discloses a coating grinding device for an auto parts electroplating hanger. The utility model replaces traditional manual grinding with machine grinding, which saves considerable time and effort and greatly improves work efficiency. The lifting mechanism adopts a screw and a nut block to cooperate, and the transmission is more stable and reliable, and the grinding is more precise. The inner side of the nut block is an inclined surface, which is convenient for the grinding mechanism to be parallel to the hanging rod on the hanger during installation. The grinding tool includes a wire roller and a round sleeve, which is convenient for replacing the grinding tool after wear. However, the coating grinding device for the auto parts electroplating hanger will generate a large amount of coating powder during grinding. If the coating powder is not treated or filtered in time, it will seriously pollute the working environment.

[0006] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a coating polishing device for an automobile parts electroplating hanger is proposed. Utility Model Content
