Description

Technical Field

[0001] The utility model relates to the technical field of painting for bushing production, in particular to a painting device for bushing production. Background Technique

[0002] A bushing is a cylindrical mechanical part sleeved on a rotating shaft. Its main functions are to protect the shaft and hole, support the transmission shaft, achieve the interference fit of the transmission shaft and the bearing of the transmission part, and reduce the friction and wear of the transmission shaft. During the production of bushings, in order to improve their anti-corrosion performance, painting operations need to be carried out on their surfaces.

[0003] The existing painting devices for bushing production mainly consist of a workbench, a clamping mechanism, and a spraying mechanism. When spraying a bushing, first place the bushing to be sprayed on the workbench and clamp it firmly through the clamping mechanism. Then start the pump body to make the paint in the storage tank flow into the spray head through the conveying pipeline. Finally, make the paint spray on the surface of the bushing through the spray head, thus completing the spraying operation on the bushing.

[0004] For the existing painting devices for bushing production, when painting bushings, most of them adopt a single-by-one painting method. Painting one by one means that only one bushing can be processed each time, which greatly reduces the painting efficiency. And in the case of mass production or when it is necessary to quickly complete the painting task, this method is obviously not the best choice. Painting one by one may lead to differences in the painting quality of each bushing, and the instability of the painting quality will affect the overall performance and appearance quality of the bushing. Therefore, a painting device for bushing production is proposed to solve the above problems. Content of the Utility Model
