Description

Technical Field

[0001] The utility model relates to the technical field of deburring, in particular to a device for deburring the inner hole of a flange part. Background Art

[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other. It is used to connect pipe ends and seal the joints between shafts, which requires extremely high precision. An oil seal groove is opened on the inner wall of the sealing hole in the middle of the flange with a cutting knife. Since the cutting knife is relatively blunt, burrs are easily generated at the opening of the oil seal groove during cutting. Since the burrs are in the sealing hole of the flange, they cannot be polished well. The means used by technicians in this field, such as the authorized patent CN201822214095.3, a deburring tool, can effectively remove burrs. However, the inner hole of some flanges is a stepped hole, which requires grinding at both ends at the same time. Therefore, a special deburring device is designed in view of the above problems.
