Specific implementation

[0019] The ferrite core double-face grinding device, including base 101 and the convex seat 103 fixedly connected in the left side of base 101, the upper side of convex seat 103 is rotatably connected with rotating rod 201, the right side of rotating rod 201 is fixedly connected with rectangular frame 203, the inside left side of rectangular frame 203 is fixedly connected with clamping semicircular plate I 204, the inside right side of rectangular frame 203 is slidably connected with clamping semicircular plate II 301, the left side of the middle part of base 101 is fixedly connected with limiting frame 102, and the limiting frame 102 is equipped with grinding mechanism.

[0020] This part is according to Figures 1-5 ​The embodiments described in 8, 9 are: in order to facilitate clamping and turning of the ferrite core to facilitate continuous ferrite core double-sided polishing work, when in use, an active end of an electric push rod is fixedly connected to the right side of the clamping semicircular plate 301 through a flange, the fixed end of the electric push rod is fixedly connected to the right middle part of the rectangular frame 203 through a bolt, at this time, the ferrite core to be polished on both sides is placed on the inner surface of the clamping semicircular plate 101 by the staff, then the electric push rod is driven to move the clamping semicircular plate 301 on the active end towards the ferrite core inside the clamping semicircular plate 101, and press the ferrite core between the clamping semicircular plate 101 and the clamping semicircular plate 301, so that the ferrite core is stably clamped by the clamping semicircular plate 101 and the clamping semicircular plate 301, then the grinding mechanism connected to the limiting frame 102 is lowered to grind one side surface of the clamped ferrite core;

[0021] When grinding the other surface of the ferrite core, the rectangular frame 203 is rotated on the upper side of the convex seat 103 by the rotating rod 201, and the ferrite core clamped by the clamping semicircular plate 101 and the clamping semicircular plate 301 in the middle part of the rectangular frame 203 is turned synchronously, so that the other surface of the ferrite core faces the grinding mechanism on the limiting frame 102, thereby grinding the other surface of the ferrite core by the grinding mechanism. It is safer than manually holding the ferrite core for grinding, preventing hand abrasions during grinding, and preventing uneven force on the ferrite core when manually holding it, which can cause uneven grinding during surface polishing. The application can ensure the stability of the ferrite core during grinding, improve safety, and facilitate observation of the grinding condition of the ferrite core surface when turning the ferrite core,

[0022] The adjacent side surfaces of the clamping semicircular plate 101 and the clamping semicircular plate 301 are rough surfaces.

The rotating position between the rotating rod 201 and the convex seat 103 has a certain friction, so when the user holds the handle and makes the rotating rod 201 drive the rectangular box 203 to flip, the friction will stabilize the rotating rod 201 at any angle when it stops rotating.
