One side of the top of the dust collection box 8 is fixedly provided with a hose 9. One end of the hose 9 is fixedly connected with the top of the back of the protective cover 6. The air inlet of the fan 10 is fixedly connected with the middle of one side of the dust collection box 8. A filter screen 11 is fixedly provided in the middle of the dust collection box 8. The fan 10 extracts the air and waste chips in the protective cover 6, and the filter screen 11 intercepts the waste chips, so that the waste chips can be concentrated in the dust collection box 8 to prevent the waste chips from affecting the surrounding production environment;

[0024] On the other side of the top of the base 1, a second vertical plate 12 is fixedly connected. The top of one side of the second vertical plate 12 is fixedly provided with an electric push rod 13. The telescopic end of the electric push rod 13 penetrates through the second vertical plate 12 and is fixedly connected with the middle of one side of the protective cover 6. The electric push rod 13 provides power for the protective cover 6, which is convenient for adjusting the positions of the protective cover 6 and the dressing tool 7, and can make the dressing tool 7 fit diamond grinding wheels of different sizes to dress diamond grinding wheels of different sizes. On one side of the top of the base 1, a side plate 14 is fixedly connected. A guide rod 15 is fixedly connected between the side plate 14 and the second vertical plate 12. The bottom end of the protective cover 6 is fixedly connected with a moving seat 16 that is slidably connected with the guide rod 15. There are two guide rods 15. The guide rods 15 limit the position where the moving seat 16 moves, so that the moving seat 16 moves linearly, and then the protective cover 6 moves linearly;

[0025] On one side of the front of the dust collection box 8, a dust outlet 17 is opened. The front of the dust outlet 17 is fixedly connected with a sealing plate 18 through bolts. Unscrewing the bolts can remove the sealing plate 18, which is convenient for removing the waste chips in the dust collection box 8. A transparent observation window 19 is fixedly provided on the front of the protective cover 6. Through the transparent observation window 19, it is convenient to observe the distance between the surface of the grinding wheel body 3 and the dressing tool 7, so as to facilitate the adjustment of the position of the dressing tool 7;

[0026] At the top of the back of the first vertical plate 2, a mounting frame 20 is fixedly connected. A driving motor 21 is fixedly provided inside the mounting frame 20. The other end of the rotating shaft 4 penetrates through the first vertical plate 2 and is fixedly connected with the transmission shaft of the driving motor 21. The driving motor 21 and the rotating shaft 4 provide power to make the grinding wheel body 3 rotate to dress the surface of the grinding wheel body 3;

[0027] Specifically, first adjust the electric push rod 13 to make the dressing tool 7 fit the outer surface of the grinding wheel body 3, dress the grinding wheel body 3, and at the same time, the protective cover 6 shields the dressing position. Then start the blower 10 to suck the waste chips in the protective cover 6 out through the hose 9, and the filter net 11 intercepts and collects the waste chips to prevent the waste chips from flying around and avoid affecting the surrounding production.

[0028] Embodiment 2:

[0029] The installation mechanism 5 includes a fixed disk 501 and a limiting cylinder 502. The fixed disk 501 is fixedly arranged in the middle of the rotating shaft 4, and the limiting cylinder 502 is threadedly connected to one end of the rotating shaft 4. An external thread that is threadedly matched with the limiting cylinder 502 is provided at one end of the rotating shaft 4. The grinding wheel body 3 is located between the fixed disk 501 and the limiting cylinder 502. The limiting cylinder 502 is threadedly connected to one end of the rotating shaft 4, so that the limiting cylinder 502 moves towards the grinding wheel body 3 to limit the position of the grinding wheel body 3. Limiting blocks 503 are fixedly connected to both the top and the bottom on one side of the fixed disk 501, and limiting holes 504 that are snap-fitted with the limiting blocks 503 are provided at both the top and the bottom on one side of the grinding wheel body 3. The limiting blocks 503 are snap-fitted with the limiting holes 504 to further limit the grinding wheel body 3, enabling the grinding wheel body 3 to rotate following the rotating shaft 4;

[0030] A first rubber pad 505 is fixedly connected to one side of the fixed disk 501, and a second rubber pad 506 is fixedly connected to one side of the limiting cylinder 502. The first rubber pad 505 and the second rubber pad 506 protect both sides of the grinding wheel body 3 and at the same time increase the friction between the grinding wheel body 3 and the limiting cylinder 502 and the fixed disk 501;

[0031] Specifically, first pass the grinding wheel body 3 through the rotating shaft 4 to make the limiting holes 504 snap-fitted with the limiting blocks 503, and then rotate the limiting cylinder 502. Under the threaded fit between the limiting cylinder 502 and the rotating shaft 4, the limiting cylinder 502 moves towards the grinding wheel body 3 to limit the grinding wheel body 3 between the limiting cylinder 502 and the fixed disk 501, thus facilitating the quick installation of the grinding wheel body 3.

[0032] During use, first pass the grinding wheel body 3 through the rotating shaft 4, align the limiting holes 504 with the limiting blocks 503 to make the limiting holes 504 snap-fitted with the limiting blocks 503, then place the limiting cylinder 502 at one end of the rotating shaft 4, and rotate the limiting cylinder 502. Under the threaded fit between the limiting cylinder 502 and the rotating shaft 4, the limiting cylinder 502 moves towards the grinding wheel body 3 to limit the grinding wheel body 3 between the limiting cylinder 502 and the fixed disk 501, thus facilitating the quick installation of the grinding wheel body 3;

[0033] Next, adjust the electric push rod 13 to drive the protective cover 6 and the dressing tool 7 to move, so that the dressing tool 7 fits against the outer surface of the grinding wheel body 3 to dress the grinding wheel body 3. At the same time, the protective cover 6 shields the dressing position. Then, start the drive motor 21 to rotate the rotating shaft 4, driving the fixed disk 501 and the grinding wheel body 3 to rotate, and dress the outer surface of the grinding wheel body 3. At the same time, start the blower 10 to suck the waste chips in the protective cover 6 out through the hose 9. The filter screen 11 intercepts and collects the waste chips to prevent the waste chips from flying around and avoid affecting the surrounding production.
