DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-7 The utility model provides a technical solution: a surface finishing device for a soft ferrite core, comprising a box body 1, the upper outer surface of the box body 1 is rotatably connected to a cover plate 10 through a rotating shaft, the lower outer surface of the cover plate 10 is fixedly connected to a magnetic plate 11, and rust removal liquid is injected into the box body 1;

[0028] A repair component 2, wherein the repair component 2 is located inside the box body 1, and removes rust from the surface of the annular magnetic core placed inside the box body 1 by means of rotational friction, thereby repairing the magnetic core;

[0029] The driving component 3 is arranged below the box body 1 , and the driving component 3 is connected to the repairing component 2 to drive the repairing component 2 .

[0030] The repair component 2 includes a turntable 33, and the outer surface of the upper end of the inner surface of the turntable 33 is fixedly connected with bristles 20, and the outer surface of the upper end of the bristles 20 is fixedly connected with a cleaning ball 21. The cross-section of the turntable 33 is a "cross" structure design, and can also be a "T" structure design. The user sticks the annular magnetic core on the magnetic plate 11 at the lower end of the cover plate 10, and the magnetic core is fixed by the magnetic plate 11, and then the cover plate 10 is covered, so that the rusted magnetic core contacts the bristles 20 inside the box body 1. When the driving component 3 drives the turntable 33 to rotate, the bristles 20 rub and wipe the magnetic core, and the residue after the rust removal liquid reacts with the rusty magnetic core is wiped off, and the repair of the magnetic core is completed. A cleaning ball 21 is provided at the upper end of the bristles 20 near the inside. When the turntable 33 rotates, the cleaning ball 21 and the bristles 20 on the inner side of the annular magnetic core are thrown toward the annular inner surface of the magnetic core by centrifugal force, thereby further ensuring the cleaning effect.

[0031] The driving component 3 includes a rotating plate 31, which is fixedly connected to the outer surface of the lower end of the turntable 33. The outer surface of the lower end of the rotating plate 31 is fixedly connected to a winding wheel 36. The annular outer surface of the winding wheel 36 is wound with a traction rope 30. A coil spring 32 is provided between the rotating plate 31 and the box body 1. One end of the coil spring 32 is fixedly connected to the outer surface of the lower end of the box body 1, and the other end of the coil spring 32 is fixedly connected to the turntable 33. When the user pulls the traction rope 30, the traction rope 30 drives the winding wheel 36, the rotating plate 31 and the turntable 33 to rotate, and at the same time accumulates force in the coil spring 32. After pulling the traction rope 30 for the first time, the user releases the pulling force, so that the turntable 33 rotates in the opposite direction under the action of the coil spring 32, driving the repair component 2 to rotate in the opposite direction to remove rust and repair the surface of the magnetic core.

[0032] Embodiment 2

[0033] The cam 35 is provided with a ratchet groove 35 on the outer surface of the lower end of the turntable 33, and the ratchet rod 34 is located inside the ratchet groove 35. Different from the above-mentioned embodiment, the user pulls the traction rope 30 to drive the rotating plate 31 to rotate, and the ratchet rod 34 acts on the surface of the ratchet groove 35 to drive the turntable 33 to rotate. When the user releases the pulling force, the rotating plate 31 is reversed and reset under the action of the coil spring 32. At the same time, the ratchet rod 34 contacts the ratchet groove 35, and the ratchet groove 35 cannot block the ratchet rod 34. When the rotating plate 31 reverses, the turntable 33 continues to rotate forward under the action of inertia. Then the user can continue to pull the traction rope 30, which can ensure that the turntable 33 maintains a high speed to drive the repair component 2 to repair the outer surface of the magnetic core.

[0034] The repair component 2 also includes a telescopic groove 25, which runs through the surface of the box body 1. A repair block 22 is slidably connected inside the telescopic groove 25. A spring 23 is fixedly connected between the repair block 22 and the box body 1. The number of the repair blocks 22 is two groups. In order to further grind and remove rust from the surface of the magnetic core, the annular outer surface of the magnetic core is grinded by the repair block 22. When the cover 10 is closed, the user manually pulls the repair block 22 to place the magnetic core into the box body 1, and then releases the repair block 22. The repair block 22 resists the annular outer surface of the magnetic core under the action of the spring 23. As the repair component 2 rotates, the annular outer surface of the magnetic core is grinded and rust removed in cooperation with the rust removal liquid.

[0035] An adjustment groove 26 is provided on the side of the repair block 22 away from the telescopic groove 25, and a guide groove 27 is provided on the inner surface of the adjustment groove 26. A guide rod 28 is slidably connected inside the guide groove 27, and a toggle ring 24 is fixedly connected to one end of the guide rod 28 away from the guide groove 27. In order to facilitate the simultaneous adjustment of the two groups of repair blocks 22, when in use, the user pushes the toggle ring 24 to drive the guide rod 28 to move up and down. The guide groove 27 is designed as an inclined structure. The toggle ring 24 and the guide rod 28 that move up and down drive the repair block 22 to move along the telescopic groove 25 through the inclined guide groove 27, thereby facilitating the placement of the magnetic core into the box body 1 and facilitating the user's operation.

[0036] The inner surface of the toggle ring 24 is fixedly connected with a slider 291 , and a slide groove 29 is provided on the annular outer surface of the box body 1 at a position corresponding to the slider 291 . The slider 291 is located inside the slide groove 29 , and both the slide groove 29 and the slider 291 are T-shaped structures, which can increase the stability of the toggle ring 24 .
