Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core processing, in particular to a magnetic core cross-section polishing and leveling 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. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has low loss characteristics. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. During the production process of the magnetic core, it is necessary to use a grinding device to polish and level its end face to ensure the flatness of the end face of the magnetic core.

[0003] For example, the patent document with the announcement number CN219725549U discloses a device for polishing and leveling the cross section of a magnetic core. It utilizes a through slot, a limit block, a screw and a clamping block to cooperate with each other. By inserting the magnetic core into the inner cavity on one side of the through slot, the end face of the magnetic core fits with the bottom of the inner wall of the limit block, and then rotating the screw to make the two clamping blocks move along the screw to clamp the top of the magnetic core. The screw is moved to drive the bottom of the magnetic core to slide in the inner cavity of the through slot, so that the end face of the magnetic core moves to the polishing wheel position, which is convenient for stable polishing of the end face of the magnetic core. However, the polishing device only has a good effect on polishing vertical cross sections. If the cross section is inclined, the clamping is easy to slip and the polishing effect is poor.
