Then, the staff member turns the X-axis handwheel 502. The X-axis handwheel 502 rotates through the X-axis screw 501 to drive the sliding base 503 to slide along the outer wall of the guide rail 504, and then the sliding base 503 slides to drive the grinding tool 609 on one side of the working frame 6 to slide, thereby facilitating the X-axis positioning operation of the grinding tool 609 and realizing the precise plane positioning operation of the grinding tool 609.

[0050] Next, the two sets of grinding tools 609 are fitted with the outer walls on both sides of the brake disc body 3. The staff turns the adjusting hand wheel 602, and the adjusting hand wheel 602 drives the lifting slider 603 to slide vertically through the adjusting screw 601. The sliding of the lifting slider 603 drives the two sets of connecting rods 604 to move synchronously, so that the sliding of the lifting slider 603 drives the connecting block 605 to slide through the connecting rod 604, and the sliding of the connecting block 605 drives the adjusting bracket 606 to slide along the outer wall of the limiting groove 607, and then the sliding of the adjusting bracket 606 drives the grinding tool 609 on the outer wall of the grinding base 608 to fit with the outer wall of the brake disc body 3.

[0051] Next, the working motor 101 drives the connecting shaft 102 to rotate, and the connecting shaft 102 rotates through the fixed frame 2 to drive the brake disc body 3 to rotate stably. At the same time, the servo motor 7 works through the process screw 701 to drive the telescopic bracket 702 to slide along the inner wall of the working frame 6, and the telescopic bracket 702 slides through the linkage groove 703 and the linkage block 704 to drive the linkage rod 705 to slide along the inner wall of the adjustment bracket 606, and then the linkage rod 705 slides to drive the grinding tool 609 on the outer wall of the grinding base 608 to slide along the diameter of the brake disc body 3, so as to facilitate the relative movement of the grinding tool 609 and the brake disc body 3, thereby realizing the stable grinding operation of the brake disc body 3.

[0052] Finally, when the grinding tool 609 grinds the brake disc body 3, a large amount of waste chips will be generated. The waste chips will fall into the discharge trough 403 in the waste trough 4 through the dust cover 8, and then the discharge motor 401 will drive the auger 402 to rotate. The spiral auger 402 rotates to drive the waste chips to be discharged from the discharge port 404, thereby avoiding the accumulation of waste chips in the waste trough 4.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
