Specific implementation manner

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1-5 , the present utility model provides a technical solution: a wind power hub bracket assembly positioning auxiliary tooling, including a support frame 1 and an assembly fine-tuning mechanism. An assembly table 2 is installed at the top of the support frame 1, and stabilizing plates 3 are installed on both sides of the top of the assembly table 2. When the assembly table 2 is used in cooperation with the stabilizing plates 3, it can perform movable support work on the external wind power hub bracket on the top of the assembly table 2, so that the user can fine-tune the position of the wind power hub bracket according to actual assembly requirements, making the position of the installation hole of the wind power hub bracket meet the assembly requirements, and avoiding the situation that it is difficult to complete the fine-tuning of the assembly of the wind power hub bracket when the assembly table 2 is used. Therefore, the assembly use convenience and flexibility of the assembly table 2 are improved.

[0033] Referring to Figures 1-5, in a preferred embodiment, the assembly fine-tuning mechanism includes a lifting cavity 4 opened inside the assembly table 2. A lifting plate 5 is movably connected inside the lifting cavity 4. Rolling grooves 6 are opened on both sides of the top of the lifting plate 5. A rolling ball 7 is movably connected inside the rolling grooves 6. A probing opening 8 is opened on the top of the assembly table 2. The rolling ball 7 penetrates through the assembly table 2 through the probing opening 8. A force-receiving seat 9 is fixedly connected to the bottom of the lifting plate 5. A force-applying strip 10 in contact with the force-receiving seat 9 is movably connected to the front side inside the lifting cavity 4. A pulling force-applying mechanism is arranged on the front side of the inner wall of the lifting cavity 4. First, move the force-applying strip 10 backward to contact the force-receiving seat 9. Since the force-applying strip 10 and the force-receiving seat 9 are in contact with an inclined surface, as the force-applying strip 10 moves backward, the force-receiving seat 9 is affected by the backward moving force of the force-applying strip 10 and applies an upward thrust to the lifting plate 5, prompting the lifting plate 5 to drive the rolling ball 7 through the probing opening 8 to protrude out of the assembly table 2 in cooperation with the rolling grooves 6, preparing for the subsequent movable support between the external wind power hub bracket and the assembly table 2. Subsequently, use an external lifting tool to hoist the external wind power hub bracket to the top of the assembly table 2. At this time, the rolling ball 7 contacts the wind power hub bracket, and the movable support work between the wind power hub bracket and the assembly table 2 is carried out, so that the user can finely adjust the position of the wind power hub bracket to make the position of the mounting holes of the wind power hub bracket meet the requirements for assembly connection with the wind power hub. The pulling force-applying mechanism includes a pulling opening 11, a pulling plate 12, and a force-applying frame 13. The pulling opening 11 is opened on the front side of the inner wall of the lifting cavity 4. The pulling plate 12 is movably connected inside the pulling opening 11. The force-applying frame 13 is fixedly connected to the rear side of the pulling plate 12. The rear side of the force-applying frame 13 is fixedly connected to the front side of the force-applying strip 10. When the force-applying strip 10 is used in cooperation with the force-receiving seat 9, it can be a medium for the user to apply a translational force to the force-applying strip 10 and reinforce the force-applying strip 10 during work, avoiding the situation that it is difficult to apply translational force when the force-applying strip 10 is used. Therefore, the convenience of using the force-applying strip 10 is improved.

[0034] Refer to Figures 2-5, in a preferred embodiment, a positioning frame 14 located at the top of the drawing opening 11 is fixedly connected to the front side of the assembly table 2. A positioning bracket 15 is movably connected inside the positioning frame 14. A positioning opening 16 is formed in the front side of the top of the drawing plate 12. The bottom of the positioning bracket 15 is located inside the positioning opening 16. When the drawing plate 12 is used in cooperation with the force application strip 10, a medium for positioning between the drawing plate 12 and the assembly table 2 can be provided for the user, avoiding the situation that it is difficult to position the drawing plate 12 during use, resulting in the force application strip 10 being difficult to apply force stably. Therefore, the positioning convenience of the drawing plate 12 is improved. Magnetic attraction strips 17 are inlaid and connected to both sides of the inner wall of the positioning frame 14, and magnetic strips 18 magnetically connected to the magnetic attraction strips 17 are inlaid and connected to both sides of the positioning bracket 15. When the positioning frame 14 is used in cooperation with the positioning bracket 15, magnetic attraction positioning work can be carried out between the positioning frame 14 and the positioning bracket 15, avoiding the situation that it is difficult to position the positioning bracket 15 after it rises during use. Therefore, the upward movement positioning convenience of the positioning bracket 15 is improved.

[0035] Refer to Figure 2 , in a preferred embodiment, translation openings 19 are formed in the front and rear sides of both sides of the top of the assembly table 2. A translation block 20 is movably connected inside the translation opening 19. The top of the translation block 20 is fixedly connected to the bottom of the stabilizing plate 3. When the stabilizing plate 3 is used in cooperation with the assembly table 2, translation limiting work can be carried out between the stabilizing plate 3 and the assembly table 2, avoiding the situation that the position of the stabilizing plate 3 deviates during use. Therefore, the use stability of the stabilizing plate 3 is improved. Connecting plates 21 are movably connected to both sides of the bottom of the assembly table 2. The top of the connecting plate 21 is fixedly connected to the bottom of the translation block 20. The bottom of the connecting plate 21 is fixedly connected to a connecting seat 22. When the translation block 20 is used in cooperation with the stabilizing plate 3, translation connection work can be carried out between the translation blocks 20 on the same side, and a translation stabilizing force can be applied to the stabilizing plate 3 by connecting with the translation block 20, avoiding the situation that the stabilizing plate 3 tilts up and down during use. Therefore, the translation stability of the stabilizing plate 3 is improved.

[0036] Refer to Figure 3, in a preferred embodiment, a screw 23 is movably connected to the bottom of the assembly table 2, a screw hole 24 is formed inside the connecting seat 22, and the screw 23 is threadedly connected to the connecting seat 22 through the screw hole 24. When the connecting seat 22 is used in cooperation with the stabilizing plate 3, a translational force can be applied to the stabilizing plate 3 through the cooperation of the connecting seat 22, the connecting plate 21, the translation block 20 and the stabilizing plate 3, avoiding the situation of translation when the stabilizing plate 3 is used. Therefore, the translational convenience of the stabilizing plate 3 is improved. A stabilizing shell 25 is fixedly connected to the bottom of the assembly table 2 and is located outside the screw 23. A stabilizing ring 26 is rotatably connected inside the stabilizing shell 25, and the inner side of the stabilizing ring 26 is fixedly connected to the surface of the screw 23. When the screw 23 is used in cooperation with the connecting seat 22, the support and stability work can be carried out between the screw 23 and the assembly table 2, avoiding the situation of position deviation when the screw 23 is used. Therefore, the use stability of the screw 23 is improved.

[0037] Specifically, the working process or principle of this assembly positioning auxiliary tooling for a wind power hub bracket is as follows: When in use, hold the positioning frame 15 and move it upward into the interior of the positioning frame 14 to prepare for subsequent entry into the positioning port 16 to position the draw plate 12. At this time, the magnetic strip 18 and the magnetic attraction strip 17 cooperate to perform magnetic attraction positioning between the positioning frame 15 and the positioning frame 14. Then, hold the draw plate 12 and cooperate with the force application frame 13 to push the force application strip 10 backward to contact the force receiving seat 9. Since the force application strip 10 and the force receiving seat 9 are in contact with an inclined surface, as the force application strip 10 moves backward, the force receiving seat 9 applies an upward thrust to the lifting plate 5 under the influence of the backward moving force of the force application strip 10, prompting the lifting plate 5 to drive the ball 7 through the detection port 8 to protrude from the assembly table 2 in cooperation with the rolling groove 6, preparing for subsequent active support between the external wind power hub bracket and the assembly table 2. After the ball 7 protrudes from the assembly table 2 through the detection port 8, the positioning port 16 moves to the bottom of the positioning frame 14 following the draw plate 12. Then, hold the positioning frame 15 and move it downward into the positioning port 16 to perform plug-in positioning between the draw plate 12 and the assembly table 2, ensuring the stability of the force applied by the force application strip 10 to the force receiving seat 9. Subsequently, use an external hoist to lift the external wind power hub bracket to the top of the assembly table 2. At this time, the ball 7 contacts the wind power hub bracket to perform active support between the wind power hub bracket and the assembly table 2, so that the user can perform fine-tuning operations on the position of the wind power hub bracket to make the position of the mounting holes of the wind power hub bracket meet the requirements for assembly connection with the wind power hub. At this time, an external cylindrical rod can be held and inserted into the mounting holes of the wind power hub bracket to prepare for subsequent alignment of the hoisted wind power hub with the wind power hub bracket. Then, use the external hoist to adjust the wind power hub to the top of the assembly table 2. At this time, the wind power hub can be moved to align the mounting holes on the wind power hub with the cylindrical rod inserted into the mounting holes of the wind power hub bracket, and the wind power hub can be moved downward to contact the wind power hub bracket. At this time, the mounting holes between the wind power hub bracket and the wind power hub are aligned under the influence of the cylindrical rod inserted into the mounting holes of the wind power hub bracket. Then, hold the screw rod 23 and rotate it to apply a translation force to the translation block 20 and the stabilizing plate 3 through the connecting seat 22 and the connecting plate 21, so that the stabilizing plate 3 moves inward to contact and press against the wind power hub bracket and the wind power hub for assembly stabilization work. At this time, the stabilizing ring 26 moves in the stabilizing hole following the screw rod 23 to support and stabilize the screw rod 23, ensuring the working stability of the stabilizing plate 3.
