[0043] Embodiment 2

[0044] Please refer to Figures 1 - 10 , the present invention provides a technical solution: An electric vehicle flywheel grinding and positioning device includes a connecting plate 1. An air shaft 2 is fixedly installed at the center of the connecting plate 1. The air shaft 2 extends into the inner ring of the flywheel. An electric telescopic rod 3 is provided on the top of the connecting plate 1. There are two electric telescopic rods 3. The electric telescopic rod 3 on the left is fixedly connected to the connecting plate 1. The electric telescopic rod 3 on the right is rotatably connected to the connecting plate 1 through an angle adjustment component 7. The inner ring of the flywheel is positioned and fixed by the air shaft 2 extending into the inner ring of the flywheel;

[0045] The extended end of the electric telescopic rod 3 is fixedly installed with an L-shaped connecting rod 4. The end of the L-shaped connecting rod 4 is fixedly installed with a connecting shaft 5. The bottom end of the connecting shaft 5 is fixedly installed with an outer ring fixing component two 9. Through the L-shaped connecting rod 4 and the connecting shaft 5, the outer ring fixing component two 9 is connected to the extended end of the electric telescopic rod 3, while avoiding the coincidence of the positions of the electric telescopic rod 3 and the air expansion shaft 2. By adjusting the position of the outer ring fixing component two 9 through the electric telescopic rod 3, the outer ring fixing component two 9 can adjust its position according to the flywheel size, ensuring that the outer ring fixing component two 9 can position and fix the outer ring of the flywheel. The overall design uses an air expansion shaft 2 with a variable diameter to position the inner ring of the flywheel, and the outer ring fixing component two 9 with adjustable position to fix the outer ring of the flywheel. It can not only position flywheels of different sizes, but also effectively prevent relative rotation between the outer ring and the inner ring of the flywheel. Through the two outer ring fixing components two 9 corresponding to the two electric telescopic rods 3, they are fixed from two positions on the outer ring of the flywheel respectively, further ensuring the stability of the fixation, and adjusting the angle of the right outer ring fixing component two 9 through the angle adjustment component 7 so that the right outer ring fixing component two 9 can correspond to the outer ring of the flywheel;

[0047] There are multiple clamping teeth 9051 on the clamping sleeve 905, and the specifications of each clamping tooth 9051 are different. For flywheels of different specifications, their tooth gaps are different. Therefore, setting multiple specifications of clamping teeth 9051 can adapt to multiple specifications of flywheels. Just drive the rotating shaft two 903 to rotate through the servo motor two 902, and then drive the connecting sleeve 904 to rotate. The rotation of the clamping sleeve 905 can align different clamping teeth 9051 with the outer ring of the flywheel;

[0048] There are multiple clamping sleeves 905, and they are distributed on the connecting sleeve 904 at a set spacing. The specifications of different clamping sleeves 905 are different. Setting multiple clamping sleeves 905 can set more specifications of clamping teeth 9051, thereby increasing the adaptation range of the outer ring fixing component two 9;

The L-shaped bracket 12 is provided for installing the electric slide rail 11. The position of the cylinder 10 is adjusted through the electric slide rail 11, and then the position of the connecting plate 1 is adjusted. The connecting plate 1 is driven to move up and down by the cylinder 10, and the position of the connecting plate 1 is further adjusted, so that the structure on the connecting plate 1 can drive the flywheel to move, and the flywheel is moved into the grinding position or moved out of the grinding position;

As the connecting shaft 5 moves, the outer ring fixing assembly two 9 on the left moves to the flywheel. Activate the servo motor two 902 to drive the rotating shaft two 903 to rotate, and further drive the connecting sleeve 904 to rotate, so that the engaging teeth 9051 on the engaging tooth set 905 that match the flywheel are aligned with the flywheel. Rotate the outer ring of the flywheel so that the tooth gap of the outer ring of the flywheel is aligned with the engaging teeth 9051. Activate the electric telescopic rod 3 to continue driving the outer ring fixing assembly two 9 to move until the engaging teeth 9051 are engaged into the tooth gap of the outer ring of the flywheel. Then, activate the servo motor one 704 to drive the rotating shaft one 705 to rotate, and further drive the gear two 706 to rotate. The gear two 706 drives the gear one 703 to rotate, and further drives the arc-shaped plate 702 to rotate.
