Description

Technical Field

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

[0002] Flange is abbreviated as flange, which usually refers to a disk-like metal body with several holes for fixing around it for connecting other things. This thing is widely used in machinery, so it looks strange, as long as it looks like it, it is called a flange. When processing it, a fixture is generally used to facilitate the positioning of the flange.

[0003] In the prior art, when processing the flange, a clamp is needed to clamp and fix the flange. When the clamp clamps and fixes the flange, the clamping member is limited and fixed by the friction between the flange and the flange. When the flange is processed, it is subjected to external force. After the flange is subjected to the external force, it is easy to overcome the friction and cause a small sliding. Relative sliding occurs between the flange and the clamping member, which reduces the clamping and fixing effect of the flange. After the flange slides, the processing position changes, thereby reducing the processing accuracy of the flange. Utility Model Content

[0023] Working process: according to the diameter of the flange, the bidirectional screw 2 is rotated to make the two moving plates 3 move toward each other, and the moving plate 3 drives the limit column 41 to move, and the distance between the two limit columns 41 is adjusted. After the distance between the two limit columns 41 is determined, the bidirectional screw 2 is stopped, and the two limit columns 41 pass through different through holes on the flange respectively. The flange moves downward under the guidance of the limit columns 41. After the flange moves a certain distance, it contacts the support ring 42, and the support ring 42 supports and limits the flange.

After the two limiting columns 41 pass through the flange, they limit and fix the corresponding parts of the flange. The flange will not rotate during the processing process, thereby improving the clamping and fixing effect of the flange.
