Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 An auxiliary device for welding the casing of a wind turbine includes an L-shaped support 1. Two strip holes 14 are symmetrically opened on the horizontal section of the L-shaped support 1. A fine adjustment mechanism is connected to each of the two strip holes 14. A docking component is installed on each of the two fine adjustment mechanisms. An L-shaped support plate 3 is installed on each of the two docking components. An installation slot 5 is opened at the top of the vertical section of each of the two L-shaped support plates 3. A rotating component is installed on each of the two rotating components. A fixing component is installed on each of the two rotating components. Four feet 17 are provided on the lower end face of the horizontal section of the L-shaped support 1, and they are respectively located at the four corners of the lower end face of the horizontal section of the L-shaped support 1.

[0023] The fine-tuning mechanism includes a servo motor 10 fixed on one side of the vertical section of the L-shaped support 1. A bearing seat 12 is fixed at the upper end of the horizontal section of the L-shaped support 1 and at one end of the strip hole 14. A threaded rod 2 is rotatably mounted on the bearing seat 12 via a bearing. One end of the threaded rod 2 is connected to the output end of the servo motor 10. A moving block 15 is screwed onto the threaded rod 2. The bottom of the moving block 15 is slidably engaged with the strip hole 14. A support plate 8 is fixed at the upper end of the moving block 15.

[0024] The docking assembly includes an electric push rod 9 fixed to one side of the upper end of the tray 8, and one end of the electric push rod 9 is connected to a movable seat 11.

[0025] L-shaped locking blocks 18 are fixed to the bottom of opposite sides of the movable seat 11. The right-angled parts of the two L-shaped locking blocks 18 are respectively slidably engaged with the two ends of the support plate 8. The stability of the movable seat 11 can be ensured by the two L-shaped locking blocks 18. The L-shaped support plate 3 is fixed to one side of the movable seat 11.

[0026] The two components of the wind turbine housing that need to be welded are placed on two movable seats 11 respectively. Two electric push rods 9 are controlled to push the two movable seats 11 closer to each other, so that the welding joints of the two components to be welded are joined together. If there is any misalignment at the joint, two servo motors 10 are started. The two servo motors 10 drive the two threaded rods 2 to rotate, which in turn causes the two movable blocks 15 to drive the two support plates 8 to move along the strip hole 14, thereby fine-tuning the position of the two components to be welded and helping to align the joints of the two components to be welded, so as to improve the welding quality.

[0027] Example 2 is an optimization based on Example 1, specifically:

[0028] The rotating assembly includes a rotating plate 4 that is rotatably mounted at the mounting slot 5 via a support pin. A first hydraulic push rod 13 is rotatably mounted between one side of the lower end face of the rotating plate 4 and one side of the vertical section of the L-shaped support plate 3.

[0029] A second hydraulic push rod 6 is fixed to the other side of the lower end face of the rotating plate 4, and a pressure block 7 is connected to the lower end of the second hydraulic push rod 6. A rubber pad 16 is provided on the lower end face of the pressure block 7, and the second hydraulic push rod 6 is located above the movable base 11.

[0030] After the component to be welded is placed on the movable seat 11, the L-shaped support plate 3 is rotated to a horizontal position by the first hydraulic push rod 13, and the pressure block 7 is moved down by the second hydraulic push rod 6 to fix the component. Then the component is moved and connected. After welding is completed, the first hydraulic push rod 13 is retracted to drive the L-shaped support plate 3 to rotate in the opposite direction, so that the second hydraulic push rod 6 and the pressure block 7 are away from the cover, preventing obstruction when removing the cover.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
