Description

Technical Field

[0001] This utility model relates to the field of paint protection tooling technology, and in particular to a paint protection tooling for the accessory mounting holes of a yaw and pitch gearbox. Background Technology

[0002] Currently, in the context of modern social development, solar energy possesses excellent development potential in the field of green energy.

[0003] In wind turbine generator sets, the oil level indicator hole and oil cup hole of the yaw and pitch gearbox need to be protected during painting before the corresponding accessories are installed to ensure that the inside of the gearbox is not contaminated by paint, so as to ensure that the oil level indicator and oil cup will not loosen due to residual paint after tightening. Since the yaw and pitch gearboxes all need to be painted as a whole for corrosion protection, the protection of non-painted parts is particularly important.

[0004] In other words, how to provide a protective tooling for the accessory mounting holes of a yaw and pitch gearbox that can prevent paint from entering the round oil level indicator hole, oil cup hole, etc., during painting, and prevent the inside of the gearbox from being contaminated by paint, thus achieving reliable protection; and how to provide a simple installation and removal method and convenient paint cleaning; at the same time, how to effectively avoid the phenomenon that the existing protective plugs are inconvenient to disassemble after installation, which affects the efficiency of operation. Utility Model Content

[0005] The purpose of this utility model is to provide a protective tool for painting the accessory mounting holes of a yaw and pitch gearbox, which solves the technical problems in the prior art where the paint on the plug cannot be removed after painting, easily causing color mixing and other appearance quality issues, as well as the technical problem that the paint cannot be removed after long-term use and the accumulated paint increases the installation and disassembly costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A protective tooling for painting the accessory mounting hole of a yaw and pitch gearbox includes: a plug body made of rubber, wherein the plug body is connected to a metal pull ring; the installation size of the plug body is larger than the size of the accessory mounting hole, so as to seamlessly seal the accessory mounting hole and fit tightly against the mounting surface.

[0007] In practical applications, the plug body is connected to the metal pull ring via a nipple screw.

[0008] The plug body, made of rubber, is formed by one-time molding.

[0009] Compared with existing technologies, the paint protection fixture for the accessory mounting holes of the yaw and pitch gearbox described in this utility model has the following advantages: In the paint protection fixture for the accessory mounting hole of the yaw and pitch gearbox provided by this utility model, the rubber plug body is connected to a metal pull ring, which facilitates easy disassembly. Since the installation size of the plug body is larger than the size of the accessory mounting hole, it allows for a seamless seal and tight fit with the mounting surface, effectively preventing paint contamination of the protective surface and ensuring a secure installation of the plug body. Therefore, the paint protection fixture for the accessory mounting hole of the yaw and pitch gearbox provided by this utility model has a simple and reliable structure, is easy to assemble and disassemble, and maintains a tight contact with the mounting hole during installation, effectively preventing loosening and improving stability. Simultaneously, the rubber material makes paint removal easier and effectively reduces manufacturing costs. Furthermore, the protective fixture has good wear resistance and corrosion resistance, and the interference fit at the mounting opening ensures a tight installation and reduces wear.

[0011] Figure label: 1-Plug body; 2-Nipple screw; 3-Metal pull ring. Detailed Implementation

[0012] For ease of understanding, the following description, in conjunction with the accompanying drawings, details the paint protection fixture for the accessory mounting holes of the yaw and pitch gearbox provided in this embodiment of the invention.

[0013] This utility model embodiment provides a protective tooling for spraying paint on the accessory mounting holes of a yaw and pitch gearbox, such as... Figure 1 As shown, it includes: a plug body 1 made of rubber, and a metal pull ring 3 connected to the plug body 1; the installation size of the plug body 1 is larger than the size of the accessory mounting hole, so as to seal the accessory mounting hole without gaps and fit tightly with the mounting surface.

[0014] Compared with the prior art, the paint protection fixture for the accessory mounting holes of the yaw and pitch gearbox described in this embodiment of the invention has the following advantages: In the paint protection fixture for the accessory mounting hole of the yaw and pitch gearbox provided in this embodiment of the present invention, the rubber plug body 1 is connected to a metal pull ring 3, which facilitates disassembly. Since the installation size of the plug body 1 is larger than the size of the accessory mounting hole, it allows for seamless sealing of the accessory mounting hole and close contact with the mounting surface, effectively preventing paint contamination of the protective surface and ensuring the plug body 1 is securely installed. Therefore, the paint protection fixture for the accessory mounting hole of the yaw and pitch gearbox provided in this embodiment of the present invention has a simple and reliable structure, is easy to assemble and disassemble, and maintains a tight contact with the mounting hole during installation, effectively preventing loosening and improving stability. Simultaneously, the rubber material makes paint removal easier and effectively reduces manufacturing costs. Furthermore, the protective fixture has good wear resistance and corrosion resistance, and the interference fit at the mounting opening ensures a tight installation and prevents wear.

[0015] In practical applications, such as Figure 1 As shown, the plug body 1 can be connected to a metal pull ring 3 by a nipple screw 2, so that the metal pull ring 3 can be quickly connected to the plug body 1 of different sizes or shapes of rubber material by means of threads, thereby realizing that one metal pull ring 3 can be adapted to multiple plug bodies 1, which greatly improves flexibility and tooling recycling rate.

[0016] The rubber plug body 1 is preferably formed by one-time casting, which makes the structure easy to process and has low processing requirements.

[0017] Specifically, such as Figure 1 As shown, the protective tooling is disassembled by reversing the operation, thereby releasing the seal and allowing it to be easily removed.

[0018] Furthermore, such as Figure 1 As shown, the metal pull ring 3 can be easily removed after the plug body 1 is installed. That is, the plug body 1 can be removed by simply pulling the metal pull ring 3, and it can effectively ensure that the unpainted area is tightly protected and not contaminated by paint.

[0019] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
