Permanent magnetic ferrite cambered surface polishing device

The utility model discloses a permanent magnetic ferrite cambered surface polishing device, and relates to the technical field of permanent magnetic ferrite processing. Comprising a workbench, a supporting structure is arranged at the bottom end of the workbench, a grinding structure is arranged on one side of the workbench and comprises a grinding disc arranged above the workbench, and a rotating structure is arranged on one side of the grinding disc. Through the arrangement of a rotating structure and a reciprocating structure, a third motor drives a rotating rod, a mounting cylinder, a ferrite arc block and a limiting rod to integrally rotate by a certain angle, and after rotation, a second motor drives a vertical rod and a second connecting rod to rotate by taking the vertical rod as a shaft; the two ends of a second connecting rod correspondingly rotate around a rotating rod and an L-shaped rod, so that the second connecting rod pulls a U-shaped block to integrally slide on a fixed track plate in a recip
