[0028] Furthermore, the fixing mechanism includes a cover body 41, an air pump 42, a fixing seat 43 and a piston 44; the cover body 41 is fixedly connected to the outer wall of the support plate 11 and covers the installation tube 3 therein, the air pump 42 is fixedly connected to the left side of the base 1, the air supply port of the air pump 42 is fixedly connected to a tee 45, and the other two interfaces of the tee 45 are respectively connected to each cover body 41 through a hose 46, one of the hoses 46 is fixedly connected to an exhaust pipe 47, and the exhaust pipe 47 is fixedly connected to a valve 48, and the fixing seat 43 is slidably connected to one end of the installation tube 3 that is close to each other, and the fixing The seats 43 are evenly arranged around the circumference of the mounting tube 3, and limiting rods 49 are fixedly connected to both sides of the fixed seat 43. The limiting rods 49 are slidably connected to the mounting tube 3. A spring 410 is sleeved on the limiting rods 49 in the mounting tube 3. The inner side of the fixed seat 43 is tilted, and the piston 44 is sealingly and slidably connected in the mounting tube 3. The side of the piston 44 close to the fixed seat 43 is fixedly connected to a spreader seat 412 through a support rod 411. The spreader seat 412 is adapted to the inclined surface on the fixed seat 43, and a positioning plate 418 is fixedly connected to the position of the mounting tube 3 close to the fixed seat 43.

[0029] Furthermore, a barometer 413 is fixedly connected to one of the covers 41 .

[0030] Furthermore, a sealing cover 414 is fixedly connected to the outer wall of the support plate 11 , a sealing disk 415 is fixedly connected to the mounting cylinder 3 , and the sealing disk 415 is movably connected in the sealing cover 414 .

[0031] Furthermore, a rubber pad 416 is fixedly connected to the outer side of the fixing seat 43 , and the rubber pad 416 is densely covered with anti-slip teeth 417 .

[0032] Furthermore, self-locking universal wheels 12 are fixedly connected to the four corners of the lower surface of the base 1 .

[0033] Furthermore, a worm gear 13 is fixedly connected to the left mounting cylinder 3, a pair of support plates 14 are fixedly connected to the inner wall of the left support plate 11, a shaft 15 is rotatably connected between the support plates 14, a knob 16 is fixedly connected to the bottom of the shaft 15, and a worm 17 meshing with the worm gear 13 is fixedly connected to the shaft 15.

[0034] Furthermore, the lead angle of the worm 17 is smaller than the equivalent friction angle between the meshing teeth of the worm 17 and the worm wheel 13 .

[0035] A specific embodiment of the present invention is:

[0036] like Figure 3 As shown, firstly, the tooling is moved to the working position by the self-locking universal wheel 12, and then the self-locking universal wheel 12 is locked, and the two half-hubs 100 are respectively mounted on the heads of the left and right mounting tubes 3, and then the half-hubs 100 are fixed by the fixing mechanism.

[0037] When the fixing mechanism is working, the air pump 42 works to deliver gas to the cover body 41 through the two hoses 46, and the gas enters the installation tube 3. Figure 5-6 As shown, with the input of gas, the pressure of the gas increases to push the piston 44 to move, and the piston 44 pushes the expansion seat 412 through the support rod 411. When the expansion seat 412 moves, it pushes each fixing seat 43 outward, thereby fixing the half hub 100.

[0038] A rubber pad 416 is fixed to the outer side of the fixing seat 43, and an anti-skid tooth 417 is provided on the rubber pad 416. The half hub 100 is fixed by the abutment between the rubber pad 416 and the anti-skid tooth 417 and the center hole of the half hub 100. The rubber pad 416 can prevent damage to the half hub 100, and the anti-skid tooth 417 can increase friction and improve the stability of the fixation.

[0039] The pressure of the gas can be monitored by the barometer 413 so that the fixing force is appropriate. After the fixing is completed, the air pump 42 is turned off. After the tire installation is completed, the valve 48 can be opened to release the air. Under the action of the spring 410, the fixing seat 43 is reset, and the piston 44 is reset.

[0040] Due to the presence of the sealing cover 414 and the sealing disk 415 , the airtightness of the installation tube 3 can be ensured, and gas leakage from the gap at the connection between the installation tube 3 and the support plate 11 can be avoided.

[0041] After the half wheel hub 100 is fixed, the tire 103 is put on the left half wheel hub 100. Figure 4 As shown, when the servo motor 22 is working, it drives the screw 24 to rotate through the coupling 27, and the moving seat 21 is slidably connected with the guide rod 25 and meshes with the screw 24. When the screw 24 rotates, it can drive the moving seat 21 to move horizontally. The moving direction of the moving seat 21 can be controlled by controlling the direction of the servo motor 22. The servo motor 22 in this application is powered by an external power supply and is provided with a forward and reverse switch for controlling its stop and start and direction, which will not be elaborated here.

[0042] When the servo motor 22 is working, it drives the moving seat 21 and the right support plate 11 to move to the left, so that the right half hub 100 moves to the left. As the two half hubs 100 get closer, the tire 103 is pressed between the two half hubs 100. During the movement, the right half hub 100 can be slightly rotated so that the fixing holes 101 on the left and right sides are aligned.

[0043] When the two half-hubs 100 are close to the rear extruded tire 103 , the positioning disc 418 can determine the lateral position of the half-hubs 100 to prevent the half-hubs 100 from lateral movement.

[0044] When the two half-hubs 100 are butted against each other, the tire 103 is pressed tightly. At this time, the bolt 102 can be passed through the fixing hole 101 to connect the two half-hubs 100. After one bolt 102 is connected, Figure 3 and Figure 7 As shown, the shaft 15 and the worm 17 can be driven to rotate by the knob 16, and the worm 17 drives the worm wheel 13 meshing therewith to rotate, thereby rotating the installation cylinder 3 on the left side. Since the two half-hubs 100 are connected by a bolt 102, the two half-hubs 100 can rotate synchronously and adjust their positions to facilitate the installation of another bolt 102. By repeating this cycle, the installation of multiple bolts 102 can be achieved.

[0045] Since the lead angle of the worm 17 is smaller than the equivalent friction angle between the meshing teeth of the worm 17 and the worm wheel 13, the worm 17 and the worm wheel 13 are self-locking, that is, the worm 17 can drive the worm wheel 13 to rotate, but the worm wheel 13 cannot drive the worm 17 to rotate. When the bolt 102 is installed, the half hub 100 will not rotate, making it inconvenient to tighten the bolt 102.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
