Description

Technical Field

[0001] The present invention belongs to an auxiliary spraying tool for the inner cavity of a composite material cylinder section, and belongs to the technical field of surface processing. Background Art

[0002] At present, the inner cavity painting of composite material cylinder sections mainly adopts the working method of manual spraying. The traditional method of manually entering the inner cavity of composite material cylinder sections for painting is inconvenient for workers due to the limitation of the working space, and the paint causes great harm to human health. At the same time, due to the low operation efficiency and uneven spraying of this method, many problems such as coating sagging and orange peel are caused. Spraying by extending an industrial robotic arm into the inner cavity of a composite material cylinder section can solve most of the problems of the above method, but this method also has the following disadvantages. First, the industrial robotic arm itself has a large volume, which reduces its flexibility in the limited working space inside the composite material cylinder section. Second, due to the large length of the inner cavity of the composite material cylinder section, it also poses great challenges to the design and operation of the robotic arm. Finally, when the robotic arm operates inside the inner cavity of the composite material cylinder section, the external cannot know the working conditions inside. The above three points are extremely likely to cause the robotic arm to damage the composite material cylinder section, resulting in serious economic losses at least and safety accidents at worst. Therefore, it is necessary to design a small, flexible and retractable auxiliary spraying tool for the spraying work of the inner cavity of composite material cylinder sections.
