Description
Technical Field
[0001] The utility model relates to the technical field of rail passenger car paint polishing, and particularly relates to a paint polishing machine. Background Technique
[0002] The paint on the rail passenger car is an important part of the rail vehicle. It not only plays a role in beautifying and protecting the vehicle, but also has certain functionality. The paint on the rail passenger car is a complex systematic project, and multiple factors need to be considered, including the substrate, the use environment, the coating performance, etc. Reasonable paint design and construction can ensure the beautiful appearance, long service life and low maintenance cost of the rail vehicle.
[0003] The rail passenger car, especially the painted part, needs to be polished frequently to maintain its appearance gloss and beauty. However, during the polishing process, the arc surface design brings inconvenience to the operation. Due to the change of the arc surface curvature, it is difficult for traditional flat polishing tools to fully fit, resulting in uneven polishing and inconsistent gloss. There are relatively few polishing tools suitable for the arc surface on the market, which limits the polishing effect and efficiency. For large-area arc surfaces, manual polishing is inefficient and prone to fatigue for operators, while the application of automated polishing equipment in the arc surface part still faces challenges.
