[0033] Usage method and working principle of this device: When in use, power on, turn on the numerical control device inside the machine case 1 and the touch display screen 7 connected thereto. Place the screw processing tool to be polished between the two jigs 615. By operating the touch display screen 7, turn on the second electromagnetic clutch 621 and start the first servo motor 617, so that the power of the first servo motor 617 is transmitted to the worm 609 through the synchronous belt 620, driving the worm gear 610, the second rotating rod 606 and the second gear 607 to rotate, and then making the movable sleeve 604 move upward.

Subsequently, the staff can close the protective door on the machine case 1, and then input the processing parameters on the touch display screen 7, including the horizontal angle of the tool (by turning on the first electromagnetic clutch 618, turning off the second electromagnetic clutch 621 and controlling the operation of the first servo motor 617, the first servo motor 617 drives the first gear 616 to rotate. Since the two first gears 616 are meshed and connected, another first gear 616 fixed at the bottom end of the first rotating rod 603 rotates, and then drives the first rotating rod 603 to rotate, realizing the adjustment of the horizontal angle of the processing placement shell 605 and the tool fixed thereon), the inclination angle (by controlling the hydraulic cylinder 505, the output end of the hydraulic cylinder 505 pushes the adjusting frame 502 to rotate. The arc-shaped groove 503 inside the adjusting frame 502 cooperates with the fixed wheel 504 fixed on one side of the support plate 501. Taking the fixed wheel 504 as the center, the adjusting frame 502 rotates, thereby changing the inclination angle of the support plate 501 and realizing the adjustment of the inclination angle of the tool), the processing inclination angle of the grinding machine 211 (start the second servo motor 210 of the grinding mechanism 2, the second servo motor 210 drives the unidirectional threaded rod 202 to rotate, making the moving block 204 move on the second limiting rod 203 and the unidirectional threaded rod 202.
