Description

Technical Field

[0001] This utility model relates to the field of wind turbine nacelle cover processing, and in particular to an auxiliary tooling for spraying paint on the surface of a wind turbine nacelle cover. Background Technology

[0002] As a crucial component of wind turbine generator sets, the wind turbine nacelle cover serves as a protective structure, enabling the generator set to operate normally in harsh weather conditions and protecting internal equipment and personnel from external environmental factors such as wind, rain, snow, salt spray, and ultraviolet radiation. The manufacturing process of the wind turbine nacelle cover requires painting. During painting, auxiliary fixtures are used to hold the nacelle cover in place. However, these fixtures sometimes obstruct parts of the nacelle cover's surface, necessitating adjustments for secondary painting during the painting process. This prolongs processing time and reduces efficiency. Therefore, this paper proposes an auxiliary fixture for painting the surface of the wind turbine nacelle cover. Utility Model Content

[0003] The main purpose of this utility model is to provide an auxiliary tooling for painting the surface of a wind turbine nacelle, which can effectively solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The output end of the hydraulic cylinder 605 is connected to one end of the drive support column 603 through the docking groove 606.

[0023] Specifically, the hydraulic cylinder 605 can drive the drive column 603 to move forward. After the drive column 603 moves forward, the connecting frame 601 moves forward. After the connecting frame 601 moves forward, it will drive the movable slider 505 to move forward, thereby controlling the positioning frame 502 to unfold.

[0024] It should be noted that this utility model is an auxiliary tooling for painting the surface of a wind turbine nacelle cover. In actual use, the wind turbine nacelle cover is first placed on the positioning shaft 3. After the wind turbine nacelle cover is placed on the positioning shaft 3, the driving hydraulic cylinder 605 can be activated. The driving hydraulic cylinder 605 will drive the driving support 603 to move forward. After the driving support 603 moves forward, the connecting frame 601 moves forward. After the connecting frame 601 moves forward, it will drive the movable slider 505 to move forward.
