Description

Technical Field

[0001] The utility model relates to the technical field of clamping structures, in particular to a fixture for flange processing. Background Art

[0002] Flange is a component used for connection, commonly used for connecting pipes. The production of flanges requires multiple processes. Because flanges are basically used for pipe connections, they are basically circular structures and have many connecting holes on them. Two flanges can be connected through the connecting holes to complete the connection of the pipe ends.

[0003] During the processing, the flange needs to be ground to avoid burrs and make it smooth, so as to ensure a tight fit without gaps when connected. The current grinding basically fixes the flange on a plane, but the current fixing method is basically through pressing, which will make the pressed area unable to be ground. The position of the flange needs to be changed to achieve the effect of comprehensive processing, which increases the complexity of the process. For this reason, a tooling fixture for flange processing is proposed. Utility Model Content
