[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] This utility model provides, for example Figure 1-4 The polycrystalline diamond composite sheet polishing device shown includes a housing 1, a mounting box 7 connected to the bottom of one side of the housing 1, a transmission component inside the mounting box 7, a discharge chute 3 connected to one side of the housing 1, a support plate 4 fixedly connected to the bottom of the housing 1, and five support legs fixedly installed on the upper surface of the support plate 4.

[0026] The transmission assembly includes a servo motor 10, which can rotate in both directions. The output shaft of the servo motor 10 is fixedly connected to a bidirectional lead screw 14. Nut seats 15 are threadedly connected to both sides of the bidirectional lead screw 14. One end of the bidirectional lead screw 14 is connected to the rotating shaft 24 via a synchronous belt 11. Synchronous pulleys are fixedly connected to the surfaces of both the bidirectional lead screw 14 and the rotating shaft 24, so that the bidirectional lead screw 14 and the rotating shaft 24 can rotate simultaneously. One end of the rotating shaft 24 is fixedly connected to a ratchet 12. A pawl 25 is rotatably connected inside the ratchet 12. One end of the pawl 25 is fixedly connected to a bevel gear set 13 via a connecting rod 23. The bevel gear set 12 rotates with the pawl 25. The bevel gear set 13 consists of two bevel gears that mesh with each other.

[0027] A polishing assembly for facilitating the polishing of polycrystalline diamond composite sheets includes a hydraulic rod 2, two fixed plates 16, a polishing table 17, and a sliding rod 20. The polishing table 17 is fixedly installed inside the housing 1. One end of the fixed plate 16 is fixedly connected to the nut seat 15. The sliding rod 20 is slidably connected to the other end of the fixed plate 16. The sliding rod 20 and the lead screw 14 allow the fixed plate 16 to only perform reciprocating linear motion, and the fixed plate 16 will not rotate. The two sides of the sliding rod 20 are fixedly installed on the two sides of the inner wall of the housing 1. One side of the fixed plate 16 is fixedly connected to the clamping block 19 through a short rod, and the other side of the clamping block 19 is set with an arc surface, which can better fix the polycrystalline diamond composite sheet. The hydraulic rod 2 is fixedly connected to the top of the housing 1. A rotating motor 18 is fixedly connected to the bottom of the hydraulic rod 2. The output shaft of the rotating motor 18 is fixedly connected to the polishing wheel 21. The polishing wheel 21 is moved up and down by controlling the hydraulic rod 2.

[0028] A feeding assembly for polishing polycrystalline diamond composite sheets is provided. The feeding assembly includes a feed box 22, with a feed tray 8 rotatably connected inside the feed box 22. The feed tray 8 includes a turntable with four feeding slots.

A feed chute 5 is connected to the other side of the feed box 22. A baffle 6 is fixedly installed on the top of the feed box 22. During the rotation of the feed tray 8, when the polycrystalline diamond composite sheet in the feeding slot comes into contact with the baffle 6, it will push the polycrystalline diamond composite sheet out into the feed chute 5. One side of the feed chute 5 is arc-shaped and is fixedly connected to the polishing table 17.

[0029] The implementation principle of the paint heating and stirring device in this embodiment is as follows: the polycrystalline diamond composite sheet is poured into the feeding box 9, the servo motor 10 is started to rotate the feed tray 8, and the polycrystalline diamond composite sheet is sent to the polishing table 17 by rotating the feed tray 8. Then the servo motor 10 is reversed. Under the action of the ratchet 12 and the pawl 25, the feed tray 8 will not rotate with the servo motor 110 after the servo motor 10 is reversed. At the same time, the bidirectional lead screw 14 drives the clamping block 19 to clamp the polycrystalline diamond composite sheet, and the hydraulic rod 2 is started to make the bottom of the polishing wheel 21 abut against the top of the polycrystalline diamond composite sheet. The rotating motor 18 is started to rotate the polishing wheel 21 to polish the polycrystalline diamond composite sheet. After polishing is completed, the servo motor 10 is reversed again. At this time, the clamping block 19 releases the polished polycrystalline diamond composite sheet under the action of the bidirectional lead screw 14. At the same time, the feed tray 8 rotates to transport a new polycrystalline diamond composite sheet to the polishing table 17. The polished polycrystalline diamond composite sheet is then pushed to the discharge trough 3 by the unpolished polycrystalline diamond composite sheet for discharge.
