[0030] The two clamping plates 18 are respectively provided with a cleaning component, the cleaning component comprises an enclosed cavity 15, an L-shaped cavity 14, a square cavity 13, a piston 20 and a reciprocating screw rod 19, the reciprocating screw rod 19 is fixedly connected to the rotating roller 12, the square cavity 13 is fixedly connected to the clamping plate 18, one end of the L-shaped cavity 14 is fixedly connected to the square cavity 13, the enclosed cavity 15 is fixedly connected to the other end of the L-shaped cavity 14, and the enclosed cavity 15 is rotatably connected to the reciprocating screw rod 19, the enclosed cavity 15 is provided with an air inlet, the piston 20 is threadedly connected to the reciprocating screw rod 19, and the cleaning component further comprises a rack plate 3, the rack plate 3 is slidingly connected to the placing table 7, the rotating rod 17 is provided with a tooth pattern, and the rack plate 3 is meshingly connected to the rotating rod 17, when the reciprocating screw rod 19 rotates with the rotating rod 17, the piston 20 can reciprocate up and down in the enclosed cavity 15, when the piston 15 moves upward and is located above the air inlet, the gas in the enclosed cavity 15 can be pushed to the surface of the semispherical soft ferrite core through the L-shaped cavity 14 and the square cavity 13, so as to blow away and clean the residues on the surface of the semispherical soft ferrite core during processing.

[0031] One end of the placing table 7 is fixedly connected with a fixed plate 10, a plurality of limiting holes 21 are equidistantly arranged on the fixed plate 10, the sliding block 9 is provided in a concave shape, and a through hole is formed in the upper surface of the sliding block 9, a limiting rod 8 is slidingly connected in the through hole, the limiting rod 8 slides downward on the sliding block 9 and slides into the limiting hole 21 on the fixed plate 10, so as to achieve the fixing effect of the disc 5 and the clamping plate 18.

[0032] In use, first pull up the limiting rod 8, so that the limiting rod 8 slides on the sliding block 9 and is disengaged from the limiting hole 21 on the fixed plate 10. Since the limiting rod 8 no longer limits the sliding block 9, the sliding block 9 can slide on the fixed plate 10 and push the disc 5 to rotate counterclockwise through the inclined rod 24. When the disc 5 and the rotating shaft 4 fixed on the disc 5 rotate, the rotating shaft 4 can drive the two horizontal plates 6 to move away from each other, respectively. With the mutual moving away of the two horizontal plates 6, the two clamping plates 18 are driven to move away from each other through the connecting rod 11, so as to place the semi-spherical soft magnetic ferrite core in the groove. At this time, the telescopic rod 23 is elongated and the lower end is pressed on the upper surface of the semi-spherical soft magnetic ferrite core, so as to achieve the fixing of the semi-spherical soft magnetic ferrite core and ensure the flatness of the semi-spherical soft magnetic ferrite core. Then, the sliding block 9 is slid on the fixed plate 10 and reset, driving the disc 5 and the rotating shaft 4 fixed on the disc 5 to rotate clockwise, and driving the two horizontal plates 6 and the clamping plate 18 to move to the center, so as to achieve the clamping effect of the semi-spherical soft magnetic ferrite core in the groove. At the same time, the two square cavities 13 move to the upper surface of the semi-spherical soft magnetic ferrite core, achieving the stable fixing of the semi-spherical soft magnetic ferrite core. Then, press down the limiting rod 8, so that the limiting rod 8 slides downward on the sliding block 9 and slides into the limiting hole 21 on the fixed plate 10, achieving the fixing effect of the disc 5 and the clamping plate 18.

[0033] When the semi-spherical soft magnetic ferrite core is fixed and processed, it needs to be rotated. First, move the sliding block 9 again and achieve a certain distance between the two clamping plates 18. Since the two rotating rollers 12 are respectively slidably connected to the clamping plates 18 and are in contact with the outer surface of the semi-spherical soft magnetic ferrite core under the elastic force of the spring 16, the rotating rollers 12 still have the clamping and fixing effect on the semi-spherical soft magnetic ferrite core. At this time, push the rack plate 3 to the right and drive the rotating rod 17 fixed on the rotating roller 12 to rotate. When the rotating roller 12 rotates, it can drive the semi-spherical soft magnetic ferrite core to rotate.

[0034] At the same time, when the reciprocating wire rod 19 rotates with the rotating rod 17, it can drive the piston 20 to move up and down in the closed cavity 15. When the piston 15 moves upward and is on the upper side of the air inlet, it can push the gas in the closed cavity 15 to the surface of the semi-spherical soft magnetic ferrite core through the L-shaped cavity 14 and the square cavity 13, so as to blow away and clean the residues on the surface of the semi-spherical soft magnetic ferrite core during processing. At the same time, when the piston 20 moves downward and is on the lower side of the air inlet, external gas can enter the closed cavity 15 from the air inlet. In this way, with the continuous rotation of the rotating roller 12, the piston 20 can be driven to move up and down by the reciprocating wire rod 19, so as to continuously blow gas to the surface of the semi-spherical soft magnetic ferrite core for cleaning.

[0035] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
