[0032] Before rotating the fourth threaded rod 721, the staff can rotate the second threaded rods 709 at both ends of the connecting frame 707 according to the width of the tile-shaped permanent magnet ferrite. Under the action of the threaded rotation of the second threaded rod 709, the sleeve frame 708 can be driven to move toward the middle of the connecting frame 707 or the side of the connecting frame 707, so that the positions of the sleeve frames 708 on both sides can be easily adjusted, so that it can be suitable for tile-shaped permanent magnet ferrites of different widths, and the blocking and limiting of tile-shaped permanent magnet ferrites of different widths can be achieved, thereby ensuring the stability and convenience of subsequent positioning work.

[0033] After the second guide rod 723 pushes the tile-shaped permanent magnetic ferrite to fit with the sleeve frame 708 through the polishing rod 716, the initial clamping of the tile-shaped permanent magnetic ferrite is completed, and the staff can rotate the fifth threaded rod 28 at the bottom of the support plate 22. At this time, the fifth threaded rod 28 drives the threaded connecting plate 29 to move upward, and then can drive the bottom fixed point of the traction rope 27 to move upward. At this time, under the elastic action of the third spring 26, the telescopic sleeve rod 24 on the connecting plate 23 can be pushed to automatically extend, and then the pressure sensor 25 can be driven to move toward the permanent magnetic ferrite until the pressure sensor The device 25 contacts the permanent magnet ferrite, and then continues to rotate the fifth threaded rod 28, leaving some margin for the traction rope 27, and begins to detect whether each tile-shaped permanent magnet ferrite is at the same center of a circle. At this time, under the driving action of the servo motor 4, the mounting plate 6 can be driven to rotate stably through the fixing frame 5, and then the fixing frame 718 can be driven to rotate synchronously, thereby driving each second guide rod 723 and each connecting frame 707 to rotate synchronously. At this time, each second guide rod 723 and the corresponding connecting frame 707 can drive the initially clamped tile-shaped permanent magnet ferrite to rotate synchronously.

[0034] During the rotation of each tile-shaped permanent magnet ferrite, if the value of the extrusion force exerted on each pressure sensor 25 does not change, it means that each tile-shaped permanent magnet ferrite is at the same center of a circle; if each tile-shaped permanent magnet ferrite is not at the same center of a circle, then under the action of the circular motion of each tile-shaped permanent magnet ferrite, the value of the extrusion force exerted on each pressure sensor 25 will change. At this time, the staff needs to adjust the position of each second guide rod 723 and the corresponding connecting frame 707 until each tile-shaped permanent magnet ferrite is at the same center of a circle.

[0035] By rotating the fourth threaded rod 721, the position of the second guide rod 723 can be adjusted through the second guide plate 722. When the position of the connecting frame 707 needs to be adjusted, it is only necessary to rotate the rotating shaft 702 on the mounting plate 6. At this time, the rotating shaft 702 can drive each of the first threaded rods 705 to rotate simultaneously through the second bevel gear 704 meshingly connected to the first bevel gear 703, and then the connecting frame 707 can be driven to move to the side or the middle at the same time through the threaded slider 706, so as to conveniently achieve the synchronous adjustment of the position of each connecting frame 707; by adjusting the position of each second guide rod 723 and the corresponding connecting frame 707, until each tile-shaped permanent magnetic ferrite is at the same center of a circle, the fifth threaded rod 28 can be rotated in the opposite direction, and the traction rope 27 can be pulled downward through the connecting plate 29, so as to drive the telescopic sleeve rod 24 to automatically retract, so as to avoid affecting the subsequent grinding work, and the tile-shaped permanent magnetic ferrites of the same batch have the same shape and size, so when grinding the tile-shaped permanent magnetic ferrites of the same batch, only one adjustment is needed.

[0036] After the adjustment is completed, the rotating shaft 702 can be rotated in the opposite direction, thereby driving the sleeve frames 708 on each connecting frame 707 to move away from the tile-shaped permanent magnet ferrite, and then by rotating the third threaded rod 710 on the connecting frame 707, under the rotation action of the third threaded rod 710, the first guide plate 711 connected by thread can push the first guide rod 712 to move toward the inner arc surface of the tile-shaped permanent magnet ferrite, and then can drive the polishing rod 716 at the first guide rod 712 to fit the inner arc surface of the tile-shaped permanent magnet ferrite, and the polishing rod 716 at the second guide plate 722 to fit the inner arc surface of the tile-shaped permanent magnet ferrite, and then under the continued driving action of the hydraulic rod 21, each tile-shaped permanent magnet ferrite is driven to continue to move upward through the support plate 22, and cooperate with the top plate 3 to achieve the extrusion and fixation of each tile-shaped permanent magnet ferrite.

[0037] After each tile-shaped permanent ferrite is squeezed and fixed, under the driving action of the servo motor 4, the mounting plate 6 and the fixing frame 718 are driven to rotate simultaneously through the fixing frame 5, thereby being able to drive each first guide rod 712 and each second guide rod 723 to perform circular motion at the same time. Combined with the grinding rods 716 at each first guide rod 712 and each second guide rod 723, the inner and outer end arc surfaces of the tile-shaped permanent ferrite can be ground simultaneously.

[0038] Before grinding, the staff can pull the first clamping rod 715 on the first guide rod 712 or the second guide rod 723 outward until it moves out of the first clamping groove 717 on the grinding rod 716. At this time, the grinding rod 716 can not only move out of the positioning groove 713 on the first guide rod 712 or the second guide rod 723 to complete the disassembly and replacement, but also move up and down; by adjusting one side of the grinding rod 716 downward to move it to the bottom of the tile-shaped permanent magnet ferrite, the first guide rod 712 or the second guide rod 723 can be loosened. The clamping rod 715, at this time, under the elastic action of the first spring 714, can drive the first clamping rod 715 to automatically engage with the first clamping groove 717 on the polishing rod 716, thereby completing the clamping fixation and position adjustment of the polishing rod 716. By adjusting the position of the polishing rod 716 at the first guide rod 712 on one side and the second guide rod 723 on one side, the polishing rods 716 on both sides are staggered with each other, and under the subsequent circular motion of the first guide rod 712 and the second guide rod 723, the inner and outer end arc surfaces of the tile-shaped permanent magnet ferrite of different lengths can be polished simultaneously.

[0039] And during the grinding process, under the rotation of the mounting plate 6, each liquid storage tank 801 can be driven to perform synchronous circular motion. At this time, the liquid storage tank 801 can drive the circular gear 805 to perform circular motion within the internal gear 806 through the spiral rod 804. Under the meshing action of the circular gear 805 and the internal gear 806, the spiral rod 804 in each conveying cylinder 803 can be driven to automatically rotate during the circular motion, and then the grinding fluid in the liquid storage tank 801 can be automatically conveyed to the nozzle 808 at the bottom end of the guide tube 807 through the conveying cylinder 803, and the permanent magnetic ferrite in the grinding process can be automatically sprayed, thereby realizing automatic dust reduction and temperature reduction of the permanent magnetic ferrite, and can also clean the grinding surface to prevent the ferrite surface from being overheated and damaged.

[0040] Moreover, during the grinding process, under the rotation of the fixed frame 718, the push plate 10 can be driven by the fixed rod 9 to perform automatic circular motion, and then the sprayed grinding fluid can be pushed into each collecting tube 15 for automatic collection, which is convenient for subsequent recycling and reuse. In the movement of the push plate 10, dust and impurities can be moved to the collection groove 18 on the filter plate 17. Under the joint action of the filter plate 17 and the collection groove 18, automatic filtering and collection of dust and impurities in the grinding fluid are achieved, ensuring the convenience of subsequent cleaning work, and at the same time avoiding blockage of the filter plate 17 during long-term operation.

[0041] After the collection tube 15 finishes working, it is only necessary to pull the second clamping rod 14 on the positioning tube 11 outward to make it move out of the second clamping groove 16 on the collection tube 15, so as to complete the convenient disassembly of the second clamping groove 16, and facilitate the subsequent transportation and recycling of the grinding fluid and impurities. Similarly, it is only necessary to insert the collection tube 15 into the original position inside the positioning tube 11, and then release the second clamping rod 14. At this time, under the elastic action of the second spring 13, the second clamping rod 14 can be automatically inserted into the second clamping groove 16 on the collection tube 15, completing the automatic clamping and fixing of the collection tube 15, and ensuring the stability of the subsequent working state of the collection tube 15.

[0042] After the grinding work is completed, it is only necessary to keep the positions of the second guide rods 723 stationary, and use the forward and reverse rotation of the rotating shaft 702 to drive the first guide rods 712 to move inward or outward, so as to realize the disassembly and positioning of each group of tile-shaped permanent magnet ferrites, thereby conveniently and efficiently completing the grinding work of the inner and outer end arc surfaces of batches of tile-shaped permanent magnet ferrites, and at the same time, it can be suitable for tile-shaped permanent magnet ferrites of different lengths, different widths and different arcs.
