[0024] The embodiment of the utility model provides a device for clamping the outer ring of a front vertical tube bearing of an electric tricycle.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including an equipment outer frame 1, a front vertical pipe member 6 and two bearing members 5, the two bearing members 5 are respectively arranged at the top and bottom of the front vertical pipe member 6, a support frame 14 is arranged at the bottom and top of one side of the front vertical pipe member 6, an arc plate 15 is arranged on one side of the two bearing members 5, a telescopic tube 11 and an air guide tube 3 13 are respectively arranged on one side of the two support frames 14, an exhaust component is arranged between the telescopic tube 11 and the air guide tube 3 13, a limiting tube 19 and a T-shaped plate 18 are arranged between the two support frames 14, and two spring-type telescopic rods 16 are arranged between one side of the T-shaped plate 18 and the support frame 14 arranged at the top.

[0026] When the utility model is in use:

[0027] A pneumatic cylinder 2 is fixedly connected to the outer frame 1 of the equipment, and a pressing part 3 for pressing the bearing part 5 is fixedly connected to the bottom of the pneumatic cylinder 2. A support part 4 is fixedly connected to the bottom of the inner cavity of the outer frame 1 of the equipment. After placing a bearing part 5 on the top of the support part 4, the front vertical pipe part 6 is placed on the top of the bearing part 5 from one side, and the top and bottom of one side of the front vertical pipe part 6 respectively press against the concave arc surface of one side of the two support frames 14. Then another bearing part 5 is placed on the top of the front vertical pipe part 6, so that the bearing part 5 is supported by the front vertical pipe part 6, and the bottom of the bearing part 5 is in contact with the top of the support frame 14 and supported by the support frame 14, ensuring the stability of the cooperation between the bearing part 5 and the front vertical pipe part 6. The two arc plates 15 fixedly connected to the two support frames 14 are held on one side of the two bearing parts 5 to limit the bearing part 5 and reduce the possibility of displacement of the bearing part 5.

[0028] In addition, an air guide pipe 2 12 is fixedly connected between one end of the telescopic tube 11 and the adjacent support frame 14, and an air guide pipe 3 13 is fixedly connected to the adjacent support frame 14. An air guide pipe 1 9 is fixedly connected between the air inlet end of the air pump 7 in the air extraction assembly and the installation box 10, and the installation box 10 is fixedly connected between the telescopic tube 11 and the air guide pipe 3 13. Therefore, the air pump 7 can extract air from the inside of the two support frames 14 through the air guide pipe 1 9, the installation box 10, the telescopic tube 11, the air guide pipe 2 12 and the air guide pipe 3 13. The position where the support frame 14 is connected to the outside is blocked by the front stand pipe 6. Therefore, after the air pump 7 is controlled to work and exhaust air from the inside of the two support frames 14, a negative pressure is generated between the front stand pipe 6 and the two support frames 14. The two support frames 14 fix the front stand pipe 6, and then the air pump 7 and the exhaust The solenoid valve 8 fixedly connected to the air outlet end of the air pump 7 stops working, and the solenoid valve 8 stops working and closes, so that the support frame 14 and the front vertical pipe member 6 are maintained in a negative pressure adsorption fixed state, and then the pneumatic cylinder 2 is controlled to work, and the pneumatic cylinder 2 pushes the pressing member 3 fixedly connected at the bottom end to move downward to press the outer ring of the bearing member 5 on the top, so that the bearing member 5 and the front vertical pipe member 6 are subjected to a downward force, and finally the two bearing members 5 are sleeved and installed on the outside of the front vertical pipe member 6, and the positions of the front vertical pipe member 6 and the two bearing members 5 are restricted by the cooperation of the two support frames 14, the two arc plates 15 and the vacuum assembly, so as to minimize the tilting of the bearing member 5 and the front vertical pipe member 6 during the force application process, reduce the possibility of processing failure, and avoid the situation where the bearing member 5 and the front vertical pipe member 6 are tilted and forced to be blown away, causing injuries to the staff.

[0029] After the top support frame 14 is stressed, it moves downward, and the telescopic tube 11 that can be telescoped ensures that the air pump 7 can pump air smoothly, so that the support frame 14 can move up and down, and the T-shaped plate 18 and the limiting tube 19 are fixedly connected to the two support frames 14 respectively, and one end of the T-shaped plate 18 extends into the limiting tube 19. The T-shaped plate 18 and the limiting tube 19 form a sliding structure with a relative position that changes up and down, and the two support frames 14 are limited to avoid tilting during the up and down movement of the top support frame 14. A fixed cross plate 17 is fixedly connected to one side of the T-shaped plate 18, and two spring-type telescopic rods 16 are fixedly connected between the fixed cross plate 17 and the support frame 14 arranged on the top. When the pneumatic cylinder 2 drives the pressing member 3 to reset, the control solenoid valve 8 is opened, so that the negative pressure between the support frame 14 and the front stand pipe member 6 is restored to a normal state from the negative pressure state, and the support frame 14 no longer fixes the front stand pipe member 6, and the rebounding spring-type telescopic rod 16 pushes the support frame 14 to reset.

[0030] In addition, the inner diameter of the support member 4 is larger than the outer diameter of the front vertical pipe member 6, providing space for the front vertical pipe member 6 to move downward. The inner diameter of the pressing member 3 is smaller than the outer diameter of the front vertical pipe member 6. After the pressing member 3 applies force to the bearing member 5 to move the bearing member 5 to the outside of the front vertical pipe member 6, it continues to apply force to the front vertical pipe member 6 to move the front vertical pipe member 6 downward.

[0031] In addition, an optional embodiment: a mounting groove 20 is provided on the top of the support frame 14. After the fixing box 21 is pressed into the mounting groove 20, when the above-mentioned "top and bottom of one side of the front vertical pipe member 6 respectively press against the concave arc-shaped surfaces on one side of the two support frames 14", a sponge block 22 is fixedly connected to the inside of the fixing box 21 and contacts the front vertical pipe member 6. Part of the lubricating oil absorbed by the sponge block 22 is smeared on the outside of the front vertical pipe member 6. Then, the front vertical pipe member 6 is rotated to smear the lubricating oil on the position of the front vertical pipe member 6 where the bearing member 5 is to be installed. Then, the bearing member 5 is installed to reduce the wear between the contact surfaces of the bearing member 5 and the front vertical pipe member 6, thereby ensuring the quality of the bearing member 5 and the front vertical pipe member 6.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
