The first polishing head 45 and the first polishing wire 46 and the second polishing wire 50 on the first polishing head 49 on the polishing rod 35 polish the inner wall of the manganese zinc ferrite magnetic core ring. As the polishing rod 35 moves downward, the spring 54 on the positioning rod 56 will be compressed, so that the second positioning cylinder 51 fits well against the top of the manganese zinc ferrite magnetic core ring. This can effectively prevent the splashing of waste chips and dust during the polishing process. Furthermore, the absorption cover 33 in the dust collection assembly, under the action of the dust collection fan, sucks the waste chips or dust generated during polishing into the chip collection box, making dust cleaning more convenient.

The first guide block 47 is fixedly installed on the slot 36. On the inner wall of the slot 36, when it is necessary to adjust the distance between the first polishing head 45 and the second polishing head 49, the turntable 38 on the rotating gear 37 is rotated, and the rotating gear 37 will rotate accordingly, thereby driving the positioning gear 42 to rotate. The corresponding first adjusting block 43 and second adjusting block 44 will move. After moving to the appropriate position, the fifth cylinder 40 works, driving the second locking protrusion 41 to move downward, so that the second locking protrusion 41 is inserted into the corresponding tooth groove on the rotating gear 37, locking the rotating gear 37, avoiding the need to replace the entire polishing head, and improving functionality.

[0016] See Figure 1 and Figure 3The protective assembly includes a first positioning cylinder 32 located at the bottom of the mounting base 17.

The first polishing head 45 and the first polishing metal wire 46 and the second polishing metal wire 50 on the first polishing head 49 on the polishing rod 35 polish the inner wall of the manganese zinc ferrite magnetic core ring. When the polishing rod 35 moves downward, the spring 54 on the positioning rod 56 will be compressed, so that the second positioning cylinder 51 fits well against the top of the manganese zinc ferrite magnetic core ring. This can effectively prevent the splashing of waste chips and dust during the polishing process. In addition, the absorption cover 33 in the dust collection assembly, under the action of the dust collection fan, sucks the waste chips or dust generated during polishing into the chip collection box, making dust cleaning more convenient.

[0017] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The drive mechanism includes a connecting seat fixedly mounted on the support column 2, a second drive motor 19 fixedly mounted on the connecting seat, the output end of the second drive motor 19 being mounted between the drive gear 20 and the drive gear 20 being meshed with the driven gear 21 mounted on the rotary seat 3; the limiting component includes an L-shaped seat 22 fixedly mounted on the connecting seat, a fourth cylinder 23 fixedly mounted on the L-shaped seat 22, the output end of the fourth cylinder 23 being fixedly mounted between the fourth cylinder 23 and the locking block 24, one end of the locking block 24 being provided with a first locking protrusion 25, the first locking protrusion 25 being inserted into the corresponding tooth groove on the drive gear 20.

[0019] See Figure 1 , Figure 2 and Figure 3 The support assembly includes a first support block 13 and a second support block 14 that move within the cavity of the polishing table 6. A first positioning block 27 is provided at the bottom of the first support block 13, and a first protrusion 26 is provided at the bottom of the polishing table 6. A screw hole on the first protrusion 26 is fitted to a first screw 28. One end of the first screw 28 is mounted to a bearing seat on the first positioning block 27 via a bearing. A second positioning block 31 is provided at the bottom of the second support block 14, and a second protrusion 29 is provided at the bottom of the polishing table 6. A screw hole on the second protrusion 29 is fitted to a second screw 30. One end of the second screw 30 is mounted to a bearing seat on the second positioning block 31 via a bearing. The position between the first support block 13 and the second support block 14 can be adjusted according to the aperture size of the manganese-zinc ferrite core ring. Rotating the corresponding first screw 28 and second screw 30 will move the corresponding positions of the first support block 13 and the second support block 14 relative to each other.

[0020] See Figure 1 The pushing assembly includes a third cylinder 15 installed in the groove at the top of the polishing table 6. The output end of the third cylinder 15 is installed between the push block 16 and the third cylinder 15. After the manganese zinc ferrite core ring is polished, the push block 16 moves forward after the third cylinder 15 is working, which can push the manganese zinc ferrite core ring into the receiving frame.

[0021] The implementation principle of a polishing device for manganese-zinc ferrite cores according to an embodiment of the present invention is as follows: The manganese-zinc ferrite core ring to be polished is placed between two first support blocks 13 and second support blocks 14 on the polishing table 6. The position between the first support blocks 13 and second support blocks 14 can be adjusted according to the aperture size of the manganese-zinc ferrite core ring. By rotating the corresponding first screw 28 and second screw 30, the positions of the corresponding first support blocks 13 and second support blocks 14 can be moved relative to each other. After the manganese-zinc ferrite core ring is positioned, the first cylinder 8 and the second cylinder 11 in the clamping assembly will operate. The first clamping block 9 and the second clamping block 12 clamp the manganese-zinc ferrite core ring. The second drive motor 19 in the drive mechanism works, driving the drive gear 20 to rotate. At the same time as the drive gear 20 rotates, the driven gear 21 also rotates, causing the rotating seat 3 to rotate. The polishing table 6 also rotates, placing the manganese-zinc ferrite core ring to be polished below the polishing mechanism. The hydraulic cylinder 5 on the support top seat 4 works, driving the mounting seat 17 to move downwards. The second positioning cylinder 51 in the shielding assembly will then fit against the top of the manganese-zinc ferrite core ring. The first drive motor 18 works, driving... The polishing rod 35 rotates, and the first polishing head 45 and the second polishing head 49 on the polishing rod 35, along with the first polishing wire 46 and the second polishing wire 50, polish the inner wall of the manganese-zinc ferrite magnetic core ring. As the polishing rod 35 moves downwards, the spring 54 on the positioning rod 56 is compressed, causing the second positioning cylinder 51 to fit snugly against the top of the manganese-zinc ferrite magnetic core ring. This effectively prevents the splashing of waste chips and dust during polishing. Furthermore, the suction hood 33 in the dust collection assembly, under the action of the dust collection fan, sucks the waste chips or dust generated during polishing into the chip collection box, thus cleaning the dust. It is more convenient, and when it is necessary to adjust the distance between the first polishing head 45 and the second polishing head 49, the turntable 38 on the rotating gear 37 is rotated, and the rotating gear 37 will rotate accordingly, thereby driving the positioning gear 42 to rotate. The corresponding first adjusting block 43 and second adjusting block 44 will move. After moving to the appropriate position, the fifth cylinder 40 works, driving the second clamping protrusion 41 to move downward, so that the second clamping protrusion 41 is inserted into the corresponding tooth groove on the rotating gear 37, and clamping the rotating gear 37. This avoids replacing the entire polishing head and improves functionality.

[0022] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
