[0034] Working principle and use process of this device: In real life, wet grinding of cemented carbide is the most common method. Liquids that usually need to be added in wet grinding are water and alcohol. Figure 1 For perspective, we will elaborate on this: S1. The output end of the second driving motor 114 drives the driving gear 115 to rotate, so that the driven gear 116 and the first cylinder 104 rotate as a whole, and then the opening opened on the first cylinder 104 faces upward, and the output end of the transmission motor 204 drives the rotating rod 202 and the toothed member 203 to rotate as a whole, and then the rack 205 moves to the right, so that the cover plate 208 first moves linearly out of the opening opened on the first cylinder 104, and then the cover plate 208 moves horizontally to the right, so as to open the opening, add the hard alloy to be ground and water or alcohol, and then the cover plate 208 is reset; S2, under the action of the output end of the second driving motor 114, the driven gear 116 and the first cylinder 104 rotate as a whole, so that the grinding ball 106 rotates and can cooperate with the annular groove 113 to grind the cemented carbide; S3. After grinding, the output end of the cylinder 110 extends, driving the baffle 109 to move upward in the second cylinder 108, and then the output end of the first drive motor 102 rotates, so that the rotating block 103 and the first cylinder 104 rotate as a whole, and then the right end of the second cylinder 108 is tilted downward. Under the action of gravity, the grinding balls 106 and the ground alloy powder enter the second cylinder 108 together, and then the output end of the cylinder 110 contracts again, driving the baffle 109 to move downward, blocking the left end of the second cylinder 108; S4. Then, under the action of the output of the first stepper motor 404, the first movable frame 405 moves to the middle of the top of the body 1, and then the first clamp 409 moves to the middle of the top of the body 1. Secondly, the output end of the second stepper motor 408 drives the second screw rod 406 to rotate, so that the first clamp 409 moves to the left along the outer surface of the second guide rod 407, and then the first clamp 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, the output end of the second stepper motor 408 rotates in the opposite direction, driving the first clamp 409 and the second cylinder 108 to move to the right as a whole and reset; S5. Under the action of the output of the first stepper motor 404, the second movable frame 410 moves to the middle of the top of the body 1, and then the movable member 414 moves to the middle of the top of the body 1. The output end of the third stepper motor 413 drives the third screw rod 411 to rotate, so that the movable member 414 and the second clamp 415 move to the left as a whole, so that the connecting ring 417 and the heating tube 416 move to the left and enter the first cylinder 104. The second clamp 415 releases the clamping of the connecting ring 417, and the electromagnetic plate 418 on the peripheral surface of the connecting ring 417 is energized, so that the connecting ring 417 is fixed to the inside of 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 located on the same straight line, the left end of the heating tube 416 is in contact with the inner left 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. S6. Then, under the action of the output of the first stepper motor 404, the first movable frame 405 moves to the middle of the top of the body 1, and then the first clamp 409 and the second cylinder 108 move to the middle of the top of the body 1 as a whole, and then the second screw rod 406 is driven to rotate by the output end of the second stepper motor 408, so that the first clamp 409 and the second cylinder 108 move to the left as a whole, and the second cylinder 108 is reset to the starting state, and the clamping mechanism 3 clamps the left end of the second cylinder 108, and the first clamp 409 releases the clamping of the second cylinder 108, and the inner diameter of the left end of the second cylinder 108 is equal to the inner diameter of the first cylinder 104, and then the first clamp 409 is reset; S7, the output end of the cylinder 110 extends, driving the baffle 109 to move upward in the second cylinder 108, and the output end of the first drive motor 102 rotates again, so that the rotating block 103 and the first cylinder 104 rotate as a whole, and 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 ball 106 and the alloy powder enter the interior of the heating tube 416 together, and the heating tube 416 is started. Under the action of the output end of the first drive 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 attached to the outer surface of the grinding ball 106, the inner wall of the first cylinder 104 and the inner wall of the second cylinder 108 evaporate, so that the alloy powder adhered thereto will fall into the interior of the heating tube 416; S8, then repeat the step S4, so that the first clamp 409 and the second cylinder 108 move to the right as a whole and reset, and the output end of the first drive motor 102 rotates at a slow speed, so that the first cylinder 104 is in a vertical state, and then the output end of the fourth stepper motor 504 drives the fourth lead screw 503 to rotate, so that the lifting member 505 and the third clamp 506 move downward as a whole, and the third clamp 506 clamps the top of the connecting ring 417, and the electromagnetic plate 418 on the peripheral surface of the connecting ring 417 is powered off and released from the inner wall of the first cylinder 104, and the output end of the fourth stepper motor 504 rotates in the opposite direction, and the heating tube 416 is pulled upward from the inside of the first cylinder 104, and the grinding balls 106 and the alloy powder are still inside the first cylinder 104; S9. Finally, the output end of the first drive motor 102 continues to rotate, so that the left end of the first cylinder 104 tilts downward. At this time, the through hole opened on the first cylinder 104 faces directly downward, and the output end of the transmission motor 204 drives the rotating rod 202 and the toothed member 203 to rotate as a whole, and then the rack 205 moves to the right, so that the cover plate 208 moves in a straight line and stops moving after disengaging from the through hole opened on the first cylinder 104. At this time, the distance between the first cylinder 104 and the cover plate 208 cannot make the grinding ball 106 fall out, and the granular alloy powder falls into the collection box 105 for collection. The whole process is automated, meeting the needs of the staff.
