[0038] The locking assembly includes a sleeve 33 and a stud 34. The stud 34 is rotatably sleeved in the sleeve 33.

The sleeve 33 is slidably sleeved on multiple insertion rods 13.

[0039] When using this equipment to grind the brake disc, firstly, the brake disc to be grinded is sleeved on the multiple insertion rods 13 through its own mounting hole, then the ferrule 33 is sleeved on the multiple insertion rods 13, and the stud 34 is screwed into the threaded hole 35. The stud 34 drives the ferrule 33 to move downward to press the brake disc onto the chuck 12, thereby fixing the brake disc.

The multiple first gears 18 respectively drive the corresponding screws 19 to rotate, so that the corresponding sliders 4 move at the same time, thereby adjusting the position of the scraper 5 to meet the working requirements.

[0041] After the position of the scraper 5 is adjusted, the equipment is started, the motor 30 rotates, driving the fifth gear 29 to rotate, and the fifth gear 29 drives the third gear ring 28 and the fourth gear ring 32 to rotate synchronously at the same time, and the rotation directions are opposite, the third gear ring 28 drives the retaining ring 27 to rotate, the fourth gear ring 32 drives the turntable 2 to rotate, the turntable 2 drives the scraper 5 to rotate, the retaining ring 27 drives the chuck 12 to rotate through the connecting rod 11, so that the brake disc rotates, the telescopic cylinder 10 shortens, so that the bottom surface of the brake disc contacts the scraper 5, and the scraper 5 rotates to grind the bottom surface of the brake disc.

[0042] During the grinding process, the telescopic cylinder 10 is continuously shortened to achieve feeding, thereby performing progressive grinding on the brake disc.

[0043] Under the grinding of the scraper 5, metal chips are generated on the lower surface of the brake disc. Under the action of gravity, the metal chips will quickly break away from the bottom surface of the brake disc, which can effectively avoid secondary scratches.

[0044] During the operation of the equipment, the turntable 2 revolves with multiple transmission shafts 24. Under the interference of the second gear ring 22, the fourth gear 26 drives the transmission shaft 24 to rotate, and the transmission shaft 24 drives the upper worm 25 to rotate. The worm 25 drives the rotating shaft 15 to rotate through the worm wheel 23, so that the rotating shaft 15 drives the pulley 14 to rotate, and the pulley 14 drives the conveyor belt 16 to operate, so that the conveyor belt 16 outputs the metal chips outward and finally guides them into the groove 8 for subsequent collection and processing. After the bottom side is polished, the upper side and the bottom side can be switched and polished again.

[0045] When this equipment is grinding, the working area is located on the bottom side, and the metal chips ground off can be separated from the brake disc surface in time, effectively avoiding secondary scratches and ensuring the grinding quality.

[0046] The multiple groups of scrapers 5 cooperate to make the bottom surface of the brake disc evenly stressed, avoid uneven stress and deviation, and further ensure the grinding quality.

[0047] During the grinding process, the driving component drives the turntable 2 and the chuck 12 to rotate in opposite directions at the same time, and drives multiple groups of scrapers 5 and brake discs to rotate in opposite directions at the same time, making the grinding more powerful and improving the work efficiency compared to only rotating the brake disc.

[0048] The metal chips produced by grinding are promptly discharged by multiple sets of conveying components to prevent them from accumulating near the brake disc, further avoiding the risk of scratches on the brake disc caused by metal chips.
