meanwhile, the two driving motors I12 are controlled to work, the two driving motors I12 drive the two grinding rollers 11 to rotate simultaneously, the two grinding rollers 11 are adjusted to be gradually close to two brake surfaces contacting with two sides of the brake disc, so that the two brake surfaces are ground simultaneously, meanwhile, the driving motor I22 drives the screw rod 24 to rotate, the screw rod 24 rotates to enable the threaded sleeve 23 to move, the threaded sleeve 23 drives the sliding seat I19 to move, the sliding seat I19 moves to change the distance from the grinding disc 20 to the excircle of the brake disc, and the grinding disc 20 is adjusted to contact with the excircle of the brake disc to be ground in the mode; when the grinding roller 11 and the grinding disc 20 move to grind, the second hydraulic rod 36 is controlled to move, the second hydraulic rod 36 drives the second sliding seat 35 to slide in a reciprocating manner, the second sliding seat 35 moves to enable the two grinding rollers 11 and the grinding disc 20 to move in a reciprocating manner to grind two braking surfaces and an excircle of a brake disc, and when grinding is performed, the nozzle 39 blows air to blow flying dust and scrap iron generated by grinding downwards, meanwhile, the dust collector 42 operates to suck and clean the falling flying dust and scrap iron through the collecting shell 41, and after the grinding is finished, the brake disc is automatically disassembled and taken down, and then the steps are repeated to clamp and polish the brake disc again, the cleaning is quicker, the cleaning mainly plays a role in auxiliary cleaning, in the scheme, the brake disc is vertically installed, scrap iron generated by polishing splashes vertically downwards, and gravity is downward, so that generated scrap iron impurities and the like can quickly leave the brake disc; compared with the mode of horizontally installing the brake disc in the prior art, the flying dust scrap iron generated by polishing falls on the horizontal brake disc surface and is difficult to clean, so that the polishing speed and the polishing quality are influenced; in the scheme, the brake disc is polished by the polishing roller 11, compared with the polishing mode of using disc-type grinding tools such as a grinding disc and the like in the prior art, the brake surface of the brake disc polished by the polishing mode is smoother, and the polishing precision is higher, because the polishing roller 11 is in line-surface contact with the brake disc, the polished brake surface is always polished and formed through one line; when tools such as a polishing disc are used for polishing, the brake disc is in surface-to-surface contact with the polishing tool, one surface is used for leveling and polishing the other surface, the polishing precision is difficult to improve, the polishing quality is low, on the basis, double-roller double-surface simultaneous polishing is adopted in the scheme, the polishing time is greatly shortened, and the polishing efficiency is improved; most importantly, in this scheme, the roller 11 of polishing when polishing, tangent line position of its axis circle in the brake disc, this position tangent line links up the tangent line for the longest on the annular braking face of brake disc, is promptly the biggest position of contact between roller 11 and the braking face of polishing, and through this kind of mode, the area of polishing in 11 unit interval of roller of polishing can reach the biggest to shorten the time of polishing, improved the efficiency of polishing: and when two grinding rollers 11 polish two brake faces, the polishing disc 20 polishes the outer circle of the brake disc at the same time, after the brake disc is clamped, polishing of the brake disc can be completed within dozens of seconds, polishing time is greatly shortened, and polishing efficiency is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
