Description

Technical Field

[0001] The present invention relates to the field of grinding devices, in particular to a circular magnetic core grinding device. Background Art

[0002] The magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials; the surface of the magnetic core is relatively rough after production, so the magnetic core needs to be processed secondary after production, which is to polish the end face of the magnetic core to make the surface of the magnetic core smooth. Patent application number: CN202323205197.6 discloses a ferrite core polishing device, including a fixed frame and a storage assembly; fixed frame: a moving assembly is installed at the left end of the upper side, a material extraction assembly is installed on the side of the fixed frame, and a polishing assembly is installed on the side of the moving assembly. The polishing assembly includes an electric telescopic rod, a fixed frame, a fourth motor and a polishing wheel. An electric telescopic rod is installed on the left side of the moving block, and a fixed frame is fixed on the telescopic arm of the electric telescopic rod. The fourth motor is installed on the upper side of the fixed frame, and a polishing wheel is fixed on the output shaft of the fourth motor. The magnetic core is polished by the polishing wheel, but this type of polishing device can only polish one side of the magnetic core at a time, which seriously affects the polishing effect.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the Invention

The positioning rod pulls the slide to move through the push plate, and the two polishing discs approach each other. After the polishing disc contacts the magnetic core, the magnetic core is polished. After the magnetic core is polished, the positioning motor drives the lead screw to rotate in the opposite direction, and the polishing disc is separated from the magnetic core to remove the magnetic core. Through this device, both sides of the magnetic core can be polished at one time, which greatly improves the polishing efficiency of the magnetic core.
