Description

Technical Field

[0001] The utility model relates to the technical field of grinding, and more specifically, to a magnetic ring burr grinding device. Background Art

[0002] The magnetic ring burr grinding device is a device used to remove burrs on the surface of the magnetic ring. During the production process of the magnetic ring, some tiny protrusions or burrs may be generated. These burrs may affect the performance and service life of the magnetic ring. Therefore, a magnetic ring burr grinding device is needed to remove these burrs to make the surface of the magnetic ring smoother and flatter.

[0003] In the existing public technical literature, the Chinese patent publication number CN205968507U discloses a magnetic ring deburring device, which uses a cylindrical magnet and a rotating shaft to be coaxial, a metal column is located between the cylindrical magnet and the rotating shaft, and the cylindrical magnet is used to fit the magnetic ring. The outer diameter of the cylindrical magnet is less than or equal to the inner diameter of the magnetic ring, and the outer diameter of the metal column is greater than the inner diameter of the magnetic ring. A movable bracket is provided on one side of the workbench, and a grinding wheel for grinding the magnetic ring is provided on the movable bracket, which can remove the burrs of the magnetic ring; the deburring device also has the following problems when in use;

[0004] When the deburring device is grinding and polishing the magnetic ring, after the magnetic ring is in contact on one side during the grinding process, the magnetic ring is switched to another side and fixed before being polished again. Moreover, the grinding is performed in a single direction with rotation. This results in not only low grinding efficiency but also poor grinding effect. Therefore, a magnetic ring burr grinding device is needed. Utility Model Content
