The mounting plate 4 drives the grinding machine to move left and right, and the electric telescopic rod drives the linear motor 3 to slide up and down in the gantry 2, so that the grinding machine moves up and down, which is convenient for adjusting the position of the grinding machine and improving the grinding efficiency. The arc-shaped clamping rail 10 drives the clamping plate 11 to move above the brake disc. At this time, the clamping plate 11 presses the top surface of the brake disc, making the brake disc more stable and safe during grinding. Pulling out the arc-shaped clamping rail 10 from the arc-shaped clamping track 9 is convenient for quickly taking out the brake disc, improving the convenience of the device. The grinding disc 5 includes a support sleeve 8, and the support sleeve 8 is fixedly connected to the upper surface of the bottom plate 1. An arc-shaped clamping track 9 is arranged at the top end of the support sleeve 8, and the arc-shaped clamping track 9 is used to clamp the brake disc conveniently.

The adjusting screw 14 is threadedly connected to the inner surface of the bottom plate 1. When the arc-shaped clamping rail 10 and the clamping plate 11 rise, a thicker brake disc can be placed between the arc-shaped clamping rails 10, which is convenient for grinding brake discs of different thicknesses and improves the applicability of the device. The limiting guide rod 12 vertically limits the arc-shaped clamping track 9, making the adjustment process of the arc-shaped clamping track 9 more stable, preventing skew, and improving the clamping accuracy.

[0024] Working principle: Install the grinding machine on the mounting plate 4, then place the brake disc on the grinding disc 5, align the grinding head with the edge of the brake disc, and then start the grinding machine to start grinding. Before grinding, start the linear motor 3. The linear motor 3 drives the grinding machine to move left and right through the mounting plate 4. At the same time, start the electric telescopic rod, and the electric telescopic rod drives the linear motor 3 to slide up and down in the gantry 2, so that the mounting plate 4 and the grinding machine move up and down, which is convenient for adjusting the position of the grinding machine and improving the grinding efficiency. After placing the brake disc on the grinding disc 5, insert the arc-shaped clamping rail 10 into the arc-shaped clamping rail 9. The arc-shaped clamping rail 10 drives the clamping plate 11 to move above the brake disc. At this time, the clamping plate 11 can press the top surface of the brake disc, making the brake disc more stable and safe during grinding. After grinding is completed, push the arc-shaped clamping rail 10 to pull it out of the arc-shaped clamping rail 9, so that the brake disc loses its limit, thereby quickly removing the brake disc and improving the usability of the device. Rotate the adjusting screw 14, the adjusting screw 14 drives the connecting convex shaft 13 to rise, the connecting convex shaft 13 drives the arc-shaped clamping rail 9 to rise, and the arc-shaped clamping rail 9 drives the arc-shaped clamping rail 10 and the clamping plate 11 to rise. At this time, a thicker brake disc can be placed between the arc-shaped clamping rails 10, which is convenient for the device to grind brake discs of different thicknesses and improves the applicability of the device. During the rising process of the arc-shaped clamping rail 9, the limit guide rod 12 is driven to slide up in the support sleeve 8. The limit guide rod 12 vertically limits the arc-shaped clamping rail 9, making the adjustment process of the arc-shaped clamping rail 9 more stable, preventing it from skewing, and improving the clamping accuracy.

At the same time, the side protection plates 61 and the front protection plate 62 can enclose the outside of the device to prevent the debris and sparks generated during grinding from splashing everywhere, improving the grinding safety. The transmission convex plate 67 drives the bolt 68 to rise and insert into the lock hole opened on the positioning plate 66, thereby locking the two positioning plates 66 to each other.

After the positioning plate 66 is locked, the inclined connecting plate 65 and the sliding top plate 64 are fixed, preventing the sliding top plate 64 from separating, improving the protection effect of the sliding top plate 64 on the internal grinding machine of the device, and preventing the sliding top plate 64 from being damaged by impact. The bolt 68 descends and withdraws from the lock hole opened on the positioning plate 66. At this time, the two sliding top plates 64 on the left and right can be quickly separated, facilitating the placement of the brake disc into the device, improving the use convenience of the device.

[0026] Working principle: During grinding, the left and right sliding top plates 64 are pushed to slide within the support sliding frame 63 and approach each other to make them fit, thereby closing the top of the device.

The sliding top plate 64 drives the inclined connecting plate 65 to approach and fit the gantry 2. The inclined connecting plate 65 then drives the positioning plates 66 to approach each other, making the upper and lower positioning plates 66 fit each other. Then, the mounting plate 4 drives the transmission convex plate 67 to rise. The transmission convex plate 67 drives the bolt 68 to rise and insert into the locking hole formed in the positioning plate 66, thereby locking the two positioning plates 66 to each other. After the positioning plate 66 is locked, the inclined connecting plate 65 and the sliding top plate 64 are fixed, preventing the sliding top plate 64 from separating, improving the protection effect of the sliding top plate 64 on the internal grinding machine of the device, and preventing the sliding top plate 64 from being damaged by impact. When grinding is required, the mounting plate 4 drives the transmission convex plate 67 to descend. The transmission convex plate 67 then drives the bolt 68 to descend and withdraw from the locking hole formed in the positioning plate 66. At this time, the left and right sliding top plates 64 can be quickly separated, facilitating the placement of the brake disc into the device, improving the convenience of use of the device.
