Problems solved by technology

[0004] The inventor found that in the mass assembly production process of the current fan production line, the application of the anti-seize agent to the bolts is still mainly done manually, the quality of the application is uneven, and the anti-seize agent The waste is serious, the quality of high-strength bolts is relatively large, and the labor intensity is high; at the same time, the glue application time of each high-strength bolt is 1-2min (taking M36X345 as an example), and more than 100 bolts are used for the yaw bearing assembly of the wind turbine. According to statistics, the number of high-strength bolts that need to be coated with anti-seize agent is 200-300 pieces, so it takes a lot of manpower and time to apply anti-seize agent to high-strength bolts;
[0005] In addition, in the process of smearing the threaded part, the use of rotating clamps is easy to damage the thread structure, and the smearing range is easy to exceed the threaded section, affecting the use of other parts of the bolt. difficult to meet demand

Embodiment 1

[0037]In a typical embodiment of the present disclosure, such asFigure 1 - Figure 2As shown, a high strength bolt anti-bite agent coating device is proposed.

[0038]It mainly includes racks, support plates 1-5, docking mechanism, drive mechanism, undertaking box 1-6 and coating mechanism;

[0039]As the support structure of other components, the support plate is mounted on the mounting plates 1-4 at the bottom of the rack, and the docking mechanism is mounted on the rack and is relatively arranged with the support plate, and the drive mechanism is mounted on the rack and connect the drive docking. The agency, thus driving the high-strength bolts 1-7 to be coated by the docking mechanism, and the drive mechanism is attached to the protective cover 1-10;

[0040]In order to facilitate the overall transfer of the device, three hanging ring screws 1-3 are installed on the rack for easy handling.

[0041]The underside is mounted on the support plate and is located on one side where the support plat...

Embodiment 2

[0066]In another typical embodiment of the present disclosure, such asFigure 1 - Figure 2As shown, a high-strength bolt bite agent coating method is proposed, and a high strength bolt bite agent coating apparatus according to Embodiment 1 is utilized.

[0067]Include the following steps:

[0068]According to the spacing of the opening and the contact axis, the head of the bolt is placed in the docking groove, and the screw is supported within the opening; the opening of the support plate is supported between the thread and the non-threaded segment of the bolt. Non-threaded segments are isolated from coating mechanisms;

[0069]The threaded segment to be coated is located between the undertaking box and the coating mechanism, and the drive mechanism is rotated by the bolt by the opposite axis;

[0070]The coating mechanism is applied to the threaded section of the bolt after coating the coating, and the box to undertake the collected coatings;

[0071]After all bolts are completed, replace the new ...

Abstract

The invention provides a high-strength bolt anti-seizure agent coating device and method, and relates to the field of wind driven generator accessory machining. The high-strength bolt anti-seizure agent coating device comprises a supporting plate and a butt joint mechanism which are oppositely arranged, at least two openings are sequentially formed in the supporting plate at intervals, the butt joint mechanism comprises at least two butt joint shafts in one-to-one correspondence with the openings, the butt joint shafts are connected with a driving mechanism capable of driving the butt joint shafts to rotate around the axis of rotation, a butt joint groove is formed in the end face, facing the openings, of the butt joint shafts, and a bearing box and a coating mechanism are installed on the side, away from the butt joint mechanism, of the supporting plate. One end of the bolt is clamped and driven, and the middle of the bolt is supported, so that the bolt is driven to rotate and support stably, the uniformity of smearing the anti-seizure agent is improved, damage to a thread structure is avoided, and the efficiency and quality of smearing the anti-seizure agent on the bolt are improved.

Description

Technical field[0001]The present disclosure relates to the field of wind turbine parts, and in particular, to a high strength bolt-bite agent coating apparatus and method.Background technique[0002]The statement of this section is merely the background technology related to the present disclosure, and it is not necessarily constituting the prior art.[0003]In the assembly of wind turbine, a large number of high-strength bolts are used, and the high-strength bolt is applied to the threaded surface to apply the anti-bite agent to prevent rust, corrosion, wear or bite phenomenon in extreme environments, and the application of anti-bite. The degree of uniformity directly determines the effect of anti-bite agents and the action time.[0004]The inventors have found that during the current fan production line batch assembly production process, the bite bolt is applied or the manual method, the coating is not uniform, the anti-bite is wasted, the high strength bolt is relatively large, and the...
