Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying devices, in particular to a paint spraying device for producing civil aircraft parts. Background Art

[0002] After the production of civil aircraft parts, such as wheel hub bearings, is completed, protective paint is sprayed on their surface to prevent problems such as rust on the civil aircraft parts. Existing civil aircraft parts are continuously moved to the painting device through a conveyor device to improve overall processing efficiency.

[0003] When the conveying device is in use, it will assist in using positioning devices such as positioning plates to limit the moving path of civil aircraft parts on the transmission device. In order to ensure the accuracy of the moving path of civil aircraft parts, one end of the positioning plate will also be located at the paint spraying device. Therefore, when the paint spraying device is in use, a certain amount of protective paint will inevitably be sprayed on the surface of the positioning plate. When the protective paint on its surface solidifies, there will be many small bumps on the positioning plate, so that when the civil aircraft parts are moved later, the surface of the civil aircraft parts will inevitably be scratched by the solidified paint blocks, resulting in incomplete surface of the civil aircraft parts. In view of the shortcomings of the existing technology, we propose a paint spraying device for the production of civil aircraft parts to solve the above problems. Utility Model Content
