Because the inner wall grinding mechanism 3, the driving mechanism 5 and the outer wall grinding mechanism 4 are all installed above the first slide rail 2, the positions of the grinding mechanism 3, the driving mechanism 5 and the outer wall grinding mechanism 4 can be freely changed laterally, which improves the flexibility of the present invention and thus improves the grinding accuracy. The outer wall grinding unit 41 and the inner wall grinding mechanism 3 can grind the outer wall and the inner wall of the diamond drill bit respectively, thereby improving the grinding efficiency. The height adjustment unit 42 enables the outer wall grinding unit 41 to grind the diamond particles on the outer wall of the diamond drill bit at different heights, thereby improving the grinding accuracy.

[0030] like Figure 2As shown, the inner wall grinding mechanism 3 includes a first slider 31, a first vertical plate 32, a lead screw 33, a connecting plate 34, a second slide rail 35, a third slider 36, a grinder 37, a third bolt 38 and a second bolt 39 (the working principles of the third bolt 38 and the second bolt 39 are the same as those of the first bolt 46). The first slider 31 is mounted to the top surface of the first slide rail 2 through the second bolt 39.

[0031] like Figure 3 As shown, the outer wall grinding unit 41 includes a grinding wheel 411, a fixing ring 412, a U-shaped plate 413, a grinding motor 414 and screws 415. The grinding wheel 411 is installed to the inside of the fixing ring 412 by three equidistantly arranged screws 415. The top of the fixing ring 412 is fixedly connected to the rotating shaft of the grinding motor 414 by the U-shaped plate 413.

The staff can also replace the grinding wheel 411 by unscrewing three equidistantly arranged screws 415. Taking downward adjustment as an example, after loosening the fourth bolt 423, the staff moves the first horizontal plate 421 downward to increase the distance between the first horizontal plate 421 and the second horizontal plate 422, and then tightens the fourth bolt 423, so that the grinding wheel 411 can cope with the lower diamond particles on the outer wall of the diamond drill bit, thereby improving the grinding accuracy.

[0032] like Figure 5As shown, the driving mechanism 5 includes a connecting ring 51, a first fixing unit 52, a connecting block 53, a driving motor 54, a fourth slider 55, a fifth bolt 56, a second fixing unit 57 and a third fixing unit 58.

The driving motor 54 is an ordinary DC motor. The rotating shaft of the driving motor 54 is used to drive the three connecting blocks 53 to rotate, and the three connecting blocks 53 drive the connecting ring 51 to rotate. Because the fixing unit 52 fixes the diamond drill base, the connecting ring 51 can drive the diamond drill base to rotate.

[0033] like Figure 6 As shown, the first fixing unit 52 and the second fixing unit 57 have the same structure. The first fixing unit 52 includes a sixth bolt 521 and a first arc-shaped clamping frame 522.

(Because the first fixing unit 52 and the second fixing unit 57 have the same structure and the same working principle, only the working principle of the first fixing unit 52 is described here, and the second fixing unit 57 will not be described in detail.) The staff tightens the sixth bolt 521 to make the first arc-shaped clamp 522 continue to approach the outer wall of the diamond drill bit base. Finally, the first arc-shaped clamp 522 is pressed against the outer wall of the diamond drill bit base. At this time, the fixation of the diamond drill bit base is completed. The first fixing unit 52, the second fixing unit 57 and the third fixing unit 58 are all used to fix the diamond drill bit base.

[0034] like Figure 3 As shown, the height of the bottom surface of the grinding wheel 411 is less than the height of the bottom surface of the fixing ring 412, so as to ensure that the bottom surface of the grinding wheel 411 grinds the outer wall of the diamond drill bit.
