[0053] The working principle and usage process of this device: In real life, wet grinding of cemented carbide is the most common method. Usually, the liquids added in wet grinding are water and alcohol. Taking Figure 1 as the perspective, a specific description is as follows:

[0054] S1. Drive the drive gear 115 to rotate through the output end of the second drive motor 114, so that the driven gear 116 and the first cylinder 104 rotate as a whole. Then, the through-hole opened on the first cylinder 104 faces directly upward. Drive the rotating rod 202 and the tooth part 203 to rotate as a whole through the output end of the transmission motor 204. Then, the rack 205 moves to the right, so that the cover plate 208 first moves linearly and disengages from the through-hole opened on the first cylinder 104, and then the cover plate 208 moves horizontally to the right, thereby realizing opening the through-hole, adding the cemented carbide to be ground and water or alcohol into it. After that, the cover plate 208 resets;

[0055] S2. Under the action of the output end of the second drive motor 114, continue to make the driven gear 116 and the first cylinder 104 rotate as a whole, so that the grinding balls 106 rotate and can cooperate with the annular groove 113 to realize grinding of the cemented carbide;

[0056] S3. After the grinding is completed, extend the output end of the cylinder 110 to drive the baffle 109 to move upward in the second cylinder 108. Then, rotate the output end of the first drive motor 102 to make the rotating block 103 and the first cylinder 104 rotate as a whole. Then, the right end of the second cylinder 108 is in an inclined downward state. Under the action of gravity, the grinding balls 106 and the ground alloy powder enter the interior of the second cylinder 108 together. After that, contract the output end of the cylinder 110 to drive the baffle 109 to move downward to block the left end of the second cylinder 108;

[0057] S4. Next, under the action of the output of the first stepping motor 404, make the first movable frame 405 move to the middle of the top of the machine body 1, and then the first fixture 409 moves to the middle of the top of the machine body 1. Secondly, drive the second lead screw 406 to rotate through the output end of the second stepping motor 408, so that the first fixture 409 moves to the left along the outer surface of the second guide rod 407. Then, the first fixture 409 clamps the right end of the second cylinder 108, and the clamping mechanism 3 releases the clamping of the left end of the second cylinder 108. After that, reverse the rotation of the output end of the second stepping motor 408 to drive the first fixture 409 and the second cylinder 108 to move to the right and reset;

[0058] S5. Under the action of the output of the first stepping motor 404, the second movable frame 410 moves to the middle of the top of the machine body 1, and then the movable part 414 moves to the middle of the top of the machine body 1. The output end of the third stepping motor 413 drives the third lead screw 411 to rotate, so that the movable part 414 and the second fixture 415 move to the left as a whole, and the connecting ring 417 and the heating tube 416 follow and move to the left and enter the inside of the first cylinder 104. The second fixture 415 releases the clamping of the connecting ring 417, and the electromagnetic plate 418 on the circumferential surface of the connecting ring 417 is energized, so that the connecting ring 417 is fixed inside the first cylinder 104. At this time, the right side surface of the connecting ring 417 and the right end surface of the first cylinder 104 are on the same straight line. The left end of the heating tube 416 is attached to the left inner wall of the first cylinder 104. The heating tube 416 and the first cylinder 104 are concentric, and the outer diameter of the heating tube 416 is smaller than the inner diameter of the first cylinder 104;

[0059] S6. Then, under the action of the output of the first stepping motor 404, the first movable frame 405 moves to the middle of the top of the machine body 1, and then the first fixture 409 and the second cylinder 108 move to the middle of the top of the machine body 1 as a whole. The output end of the second stepping motor 408 drives the second lead screw 406 to rotate, so that the first fixture 409 and the second cylinder 108 move to the left as a whole. The second cylinder 108 returns to the initial state, and the clamping mechanism 3 clamps the left end of the second cylinder 108. The first fixture 409 releases the clamping of the second cylinder 108. The inner diameter of the left end of the second cylinder 108 is equal to the inner diameter of the first cylinder 104. After that, the first fixture 409 returns to its original position;

[0060] S7. The output end of the cylinder 110 extends, driving the baffle 109 to move upward in the second cylinder 108. The output end of the first driving motor 102 rotates again, so that the rotating block 103 and the first cylinder 104 rotate as a whole. Then, the first cylinder 104 and the second cylinder 108 are in a vertical state as a whole. Under the action of gravity, the grinding balls 106 and the alloy powder enter the inside of the heating tube 416 together. The heating tube 416 is started, and under the action of the output end of the first driving motor 102, the first cylinder 104 and the second cylinder 108 are in a swinging state as a whole, so that the water or alcohol adhering to the outer surface of the grinding balls 106, the inner wall of the first cylinder 104 and the inner wall of the second cylinder 108 volatilizes, and the alloy powder adhered to them will fall into the inside of the heating tube 416;

[0061] S8. Then repeat the steps of S4 to move the first fixture 409 and the second cylinder 108 as a whole to the right and reset. Rotate the output end of the first drive motor 102 at a slow speed to make the first cylinder 104 in a vertical state. Then drive the fourth lead screw 503 to rotate through the output end of the fourth stepper motor 504, so that the lifting member 505 and the third fixture 506 move downward as a whole. The third fixture 506 clamps the top of the connecting ring 417. The electromagnetic plate 418 on the circumferential surface of the connecting ring 417 is powered off and releases the fixation with the inner wall of the first cylinder 104. The output end of the fourth stepper motor 504 rotates in the reverse direction, and the heating tube 416 is pulled upward from the inside of the first cylinder 104. The grinding balls 106 and the alloy powder are still inside the first cylinder 104;

[0062] S9. Finally, continue to rotate the output end of the first drive motor 102 to make the left end of the first cylinder 104 tilt downward. At this time, the through-hole opened on the first cylinder 104 faces directly downward. Drive the rotating rod 202 and the toothed member 203 to rotate as a whole through the output end of the transmission motor 204. Then the rack 205 moves to the right, so that the cover plate 208 moves linearly and disengages from the through-hole opened on the first cylinder 104 and then stops moving. At this time, the distance between the first cylinder 104 and the cover plate 208 cannot allow the grinding balls 106 to fall out, while the granular alloy powder falls into the collection box 105 for collection. The whole process is automated, meeting the needs of the staff.
