The worm gear drives the first threaded rod with internal spiral connection to rise. The first threaded rod drives the top plate connected to the top to rise. The top plate applies pressure to the lifting plate set in contact with the outside to push it up. The lifting plate drives the top support plate and the generator body to rise, thereby realizing rapid movement of the generator body, reducing the labor intensity of the staff and improving work efficiency.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 5 shown, the present invention provides a generator alignment tooling, including an L-shaped plate 1, a support block 8 and a working box 12. One side of the upper part of the L-shaped plate 1 is fixedly connected with an electric push rod 2, and one side of the lower part of the L-shaped plate 1 is fixedly connected with a spring 3. One end of the spring 3 is fixedly connected with a push plate 4, which can fix the position of the generator body 7 to prevent shaking and deviation. One side of the push plate 4 is closely provided with a support plate 5. The bottom end of the support plate 5 is fixedly connected with a brake wheel 6, and the top end of the support plate 5 is fixedly connected with the generator body 7. One side of the support block 8 is fixedly connected with an alignment block 9. A coupling 10 is sleeved inside the support block 8, and a rotating shaft 11 is key-connected inside the coupling 10.

[0026] Specifically, a worm 13 is rotatably connected inside the working box 12. There is a counterweight block inside the working box 12 to increase the stability of the device. The outer side of the worm 13 is meshed with a worm gear 14. A first threaded rod 15 is helically connected inside the worm gear 14. The top end of the first threaded rod 15 is rotatably connected with a top plate 16, and a lifting plate 17 is closely provided outside the top plate 16.

[0027] Furthermore, a laser alignment instrument 25 is movably provided on one side of the support block 8, and the laser alignment instrument 25 is flush with the axis of the rotating shaft 11, which is convenient for workers to measure the offset and angular deviation and adjust in time to reduce damage.

[0028] Still further, an offset groove 18 is opened at the top end of the lifting plate 17, and the brake wheel 6 slides inside the offset groove 18 to limit the brake wheel 6 and provide a guiding function to prevent it from driving the generator body 7 to move randomly.

[0029] It is worth noting that a slider 19 is slidably connected inside the offset groove 18, and a second threaded rod 20 is helically connected inside the slider 19, which can finely adjust the position of the generator body 7 to make its alignment better and reduce wear.

[0030] It should be noted that one end of the worm 13 is fixedly connected with a servo motor 26, and the bottom end of the servo motor 26 is fixed on the inner wall bottom surface of the working box 12. The servo motor 26 rotates and drives the worm 13 fixedly connected to the end of its output shaft to rotate, eliminating the need for manual rotation by workers, reducing labor intensity and improving work efficiency.

[0031] It is worth introducing that a support seat 21 is sleeved outside the worm 13, and a bearing 22 is embedded inside the support seat 21, and the bearing 22 is sleeved outside the worm 13. Under the action of the bearing 22, the friction coefficient between the worm 13 and the support seat 21 can be reduced, the rotation accuracy of the worm 13 can be ensured, and the energy consumption can be reduced.

[0032] It is worth emphasizing that a polished rod 23 is inserted and connected inside the lifting plate 17, and a limit piece 24 is fixedly connected to the top end of the polished rod 23. Under the action of the polished rod 23, it plays a guiding role in the movement of the lifting plate 17, preventing deviation during the movement and causing the generator body 7 to move, resulting in a poor centering effect.

[0033] Among them, the electric push rod 2, the generator body 7, the coupling 10, the bearing 22, the laser aligner 25 and the servo motor 26 are prior arts and will not be elaborated; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated.

[0034] Working principle and process:

[0035] When the alignment installation of the generator body 7 is required, start the electric push rod 2 to push the generator body 7 to slide on the support plate 5. After the output shaft of the generator body 7 contacts the alignment block 9, since the inside of the alignment block 9 is an arc structure, if the alignment is offset, the output shaft of the generator body 7 will drive the generator body 7 to offset. The generator body 7 drives the brake wheel 6 fixedly connected to the bottom end of the support plate 5 to slide inside the offset groove 18, limit the brake wheel 6, provide a guiding function, and prevent it from driving the generator body 7 to move randomly and the generator body 7 to deflect. During this period, the support plate 5 pushes the push plate 4, and the push plate 4 compresses the spring 3 to fix the position of the generator body 7, prevent shaking and offset, and achieve the rapid alignment of the axis of the key-connected rotating shaft 11 inside the generator body 7 and the coupling 10. Without the need for staff to manually move the generator, the labor intensity is reduced, the alignment effect is good. After the alignment is completed, lock the brake wheel 6 to fix the position of the generator body 7, start the laser aligner 25 movably arranged on one side of the support block 8 to measure the offset and angular deviation, rotate the second threaded rod 20 to drive the slider 19 to slide inside the offset groove 18, and finely adjust the position of the generator body 7 to make its alignment better and reduce wear. When the height of the generator body 7 is not good and alignment cannot be performed, start the servo motor 26 fixedly connected to the inner bottom surface of the rotating work box 12 to make the servo motor 26 drive the worm 13 fixedly connected to the end of its output shaft to rotate. Without the need for staff to manually rotate, the labor intensity is reduced and the work efficiency is improved. Under the action of the bearing 22, the friction coefficient between the worm 13 and the support seat 21 can be reduced, the rotational accuracy of the worm 13 can be ensured, and energy consumption can be reduced. The worm 13 drives the externally meshed worm wheel 14 to rotate, and the worm wheel 14 drives the internally screwed first threaded rod 15 to rise. The first threaded rod 15 drives the top plate 16 rotatably connected to its top to rise. The top plate 16 applies pressure to the lifting plate 17 attached to the outside to push it up. The lifting plate 17 drives the support plate 5 at the top and the generator body 7 to rise. Under the action of the optical rod 23, it plays a guiding role in the movement of the lifting plate 17 to prevent offset during the movement, resulting in the movement of the generator body 7 and poor alignment effect, and realizes the rapid movement of the generator body 7, reduces the labor intensity of the staff, and improves the work efficiency.
