The working process is as follows:
S1, when the self-adaptive tire polishing machine is used, a tire to be polished is sleeved on a first expansion mechanism 2, then a hydraulic rod 102 is started, and the hydraulic rod 102 drives a second expansion mechanism 3 to move towards the direction of the first expansion mechanism 2, so that a first self-adaptive assembly 23 and a second self-adaptive assembly 33 are mutually staggered, and two ends of the first self-adaptive assembly and the second self-adaptive assembly are aligned;
S2, then rotating the first adjusting disk 22 and the second adjusting disk 32, wherein in the process of rotating the first adjusting disk 22 and the second adjusting disk 32, the first sliding block 232 slides in the first through groove 221, the second sliding block 233 slides in the first sliding groove 211, the third sliding block 332 slides in the second through groove 321, and the fourth sliding block 333 slides in the second sliding groove 311, so that the first adaptive assembly 23 and the second adaptive assembly 33 are driven to be supported outwards, the first adaptive assembly 23 and the second adaptive assembly 33 are supported on the inner side of the tire, the first connecting frame 239, the second connecting frame 243, the third connecting frame 339 and the fourth connecting frame 343 clamp the inner edge of the tire, and the first top block 241 and the second top block 341 are supported on the inner side of the tire;
S3, starting a first driving piece 101 and a second driving piece 404, wherein the first driving piece 101 drives the first expansion mechanism 2 and the second expansion mechanism 3 to rotate, the first expansion mechanism 2 and the second expansion mechanism 3 rotate the tire, the second driving piece 404 drives a driving wheel 405 to rotate, the driving wheel 405 drives a driven wheel 406 to rotate through a transmission belt 407, the driven wheel 406 drives a grinding roller 403 to rotate, and the grinding roller 403 rotates in the opposite direction;
s4, starting a second linear module 107, wherein the second linear module 107 drives the polishing mechanism 4 to move towards the tire, and starting the first linear module 103 after the polishing roller 403 is close to the tire, so as to drive the polishing roller 403 to move and polish the tire;
S5, because the number of the first top blocks 241 and the second top blocks 341 is multiple, the adjacent first top blocks 241 are distributed in a vertically staggered way, the adjacent second top blocks 341 are distributed in a vertically staggered way, the first adaptive assembly 23 and the second adaptive assembly 33 are mutually staggered in the circumferential direction and are aligned at two ends, the adjacent second top blocks 341 and the first top blocks 241 are distributed in a vertically staggered way, when the grinding roller 403 contacts with part of the tyre jacked by the first top blocks 241 or the second top blocks 341 in the moving process of the grinding roller 403, the first top block 241 or the second top block 341 on the upper top is extruded in the grinding process and then descends downwards, the second rack 240 or the fifth rack 340 drives the adjacent first rack 238, second rack 240, third rack 242 or fourth rack 338, fifth rack 340 and sixth rack 342 on the same first self-adaptive component 23 or second self-adaptive component 33 through the first gear 235, the second gear 236, the third gear 237 or the fourth gear 335, the fifth gear 336 and the sixth gear 337, so as to drive the adjacent first connecting frame 239, the first jacking block 241, the second connecting frame 243 or the third connecting frame 339, the second jacking block 341 and the fourth connecting frame 343 on the same first self-adaptive component 23 or second self-adaptive component 33 to jack up the position to be polished later;
S6, the outer diameter of the tire after being jacked up at the inclined and eccentric wear position is larger than the outer diameter of the tire after being jacked up at the position without inclined and eccentric wear, so that the polishing effect on the inclined and eccentric wear position of the tire is stronger, and the position without inclined and eccentric wear on the tire is polished normally, so that all parts on the tire can be polished uniformly, and the situation that the polished tire surface is deflected is avoided;
And S7, when the position of the tire, which is jacked by the first jack block 241 or the second jack block 341, is polished and lowered, the position of the tire, which is jacked by the first jack block 241 or the second jack block 341 and is adjacent to the first jack block 241 or the second jack block 341 in the circumferential direction and the axial direction, is jacked upwards, and the elasticity of the tire is utilized, so that the stress of each part is the same when the tire is polished, and the condition that the tire swings due to uneven stress in the polishing process is avoided.
