[0029] Working principle: when performing specific work, first connect the entire device to the external safety mains, then open the protective door 30; then control the telescopic cylinder 5 to start, and the telescopic cylinder 5 will drive the placing seat 6 to move to the top of the opening 7; when the telescopic cylinder 5 starts to reach the top, the placing seat 6 is just located above the opening 7; then place the gear in the placing groove 12 on the placing seat 6, then close the protective door 30, and complete the manual feeding work.

[0030] When the protective door 30 is closed, the clamping telescopic cylinder 14 is first controlled to start. After the clamping telescopic cylinder 14 starts, the clamping movable seat 15 is driven to move towards the placement seat 6. In the process of moving the clamping movable seat 15, the stepping motor 16, the clamping disc 17 and the clamping piece 18 are synchronously moved together until the end of the clamping piece 18 with the magnet block 19 is attached to the side surface of the gear. Because the attraction force can be generated between the magnet block 19 and the gear, the clamping piece 18 can well fix the position of the gear. After the clamping pieces 18 on the clamping discs 17 on both sides fix the gear, the clamping telescopic cylinder 14 is first controlled to pause, and then the telescopic cylinder 5 is controlled to stop. In the process of stopping the telescopic cylinder 5, the placement seat 6 is driven to move towards the telescopic cylinder 5 from above the opening 7 and move out. In the process of moving the placement seat 6, the gear is moved out of the feeding port of the placement groove 12 and separated from the placement seat 6.

[0031] After the gear is completely separated from the placement seat 6, the push-out cylinder 26 is first controlled to start. After the push-out cylinder 26 starts, the push-out seat 27 is driven to move directly below the opening 7. After the movement stroke of the push-out cylinder 26 reaches the top, the push-out seat 27 is located directly below the opening 7. Then the lifting cylinder 31 is controlled to start. After the lifting cylinder 31 starts, the heat-conducting silicon powder disc 8 is driven to move towards the partition plate 2. Finally, the heat-conducting silicon powder disc 8 is moved above the partition plate 2 through the opening and contacts the bottom surface of the gear. At this time, the lifting cylinder 31 is first controlled to pause, and then the stepping motor 16 is controlled to start. After the stepping motor 16 starts, the clamping disc 17 is rotated, and in the process of rotating the clamping disc 17, the gear is synchronously rotated through the clamping piece 18. In the process of rotating the gear, the outer side surface of the gear continuously contacts the heat-conducting silicon powder in the heat-conducting silicon powder disc 8, so that a layer of heat-conducting silicon powder can be adhered to the outer side surface of the gear (generally, the number of rotations of the gear at this time is two to three rotations). After the surface of the gear is evenly covered with heat-conducting silicon powder, the stepping motor 16 is first controlled to stop, and then the lifting cylinder 31 and the push-out cylinder 26 are controlled to stop in turn, so that the heat-conducting silicon powder disc 3 is moved from the opening 7 to below the partition plate 2 and finally hidden below the partition plate 2 from directly below the opening 7, completing the operation of the heat-conducting silicon powder on the gear.

[0032] After the equal-thermal silicon powder disc 3 is hidden back below the partition plate 2, the control controls the driving motor 23 to start, the driving motor 23 starts to drive the driving shaft 21 to rotate, the driving shaft 21 rotates to drive the grinding belt 3 to move, the grinding belt 3 moves to drive the driven shaft 22 to rotate, and the driven shaft 22 and the driving shaft 21 rotate synchronously to make the grinding belt 3 move in a cycle and rotate at a high speed; then the clamping translation cylinder 32 is controlled to start, the clamping translation cylinder 32 is started to move the clamping translation seat in the direction of the grinding belt 3, the clamping translation seat moves to drive the clamping disc 17, the clamping piece 18 and the gear to move together, so that the gear can contact the grinding belt 3; when the gear contacts the grinding belt 3, the diamond particle layer 9 contacts the gear first and generates friction between the gear to complete the accurate grinding work on the teeth of the gear; at the same time of the grinding work, the anti-oxidation liquid spraying pipe 4 sprays the anti-oxidant between the grinding belt 3 and the gear, the anti-oxidant not only can maintain the position of the gear cup grinding, reduce unnecessary grinding caused by oxidation, to ensure the accuracy of the grinding, but also the flowing anti-oxidant can take away the temperature on the gear and the grinding belt 3, and because the surface of the gear is coated with thermal silicon powder, the heat dissipation effect of the thermal silicon powder is used, under the heat dissipation effect of the anti-oxidant and the thermal silicon powder, the maximum cooling work of the gear can be realized to avoid the internal deformation of the gear due to high temperature, further ensuring the grinding effect; after one tooth of the gear is ground, the clamping translation cylinder 32 is controlled to stop, the gear is separated from the grinding belt 3, then the step motor 16 is controlled to start according to the angle between the gear and each adjacent two teeth, the step motor 16 starts to drive the clamping disc 17 and the gear to align the next grinding place to the grinding belt 3, then according to the previous grinding steps, the clamping translation cylinder 32 is controlled to start again to perform the next grinding work.

[0033] The waste liquid generated in the grinding process will fall on the partition plate 2 or through the opening 7 fall to the bottom surface of the machining box 1, because the partition plate 2 is funnel-shaped as a whole, so that the waste liquid falling on the partition plate 2 will slowly move along the arc of the partition plate 2 to the opening 7 direction, automatically hit the bottom surface of the machining box 1, and finally be discharged through the waste liquid discharge pipe 28; when all the teeth on the gear complete the grinding work, first control the driving motor 23 to stop and the anti-oxidation liquid spraying pipe 4 to stop spraying the anti-oxidant, so that the grinding belt 3 stops rotating, then control the clamping translation cylinder 32 to stop, so that the gear is separated from the grinding belt 3; then control the telescopic cylinder 5 to start, after the telescopic cylinder 5 starts, it will drive the placing seat 6 to move to the gear direction, during the movement of the placing seat 6, the gear will push away the elastic element at the inlet and enter the placing groove 12, so that the placing seat 6 can support the gear; then control the clamping telescopic cylinder 14 to stop, after the clamping telescopic cylinder 14 stops, it will drive the clamping disc 17 and the clamping element 18 to move away from the gear, so that the clamping element 18 is separated from the gear, finally open the protection door 30 to take down the gear on the placing seat 6 which completes the grinding, waiting for the next grinding work.
