[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, a positioning fixture for flange processing according to this utility model includes a worktable 1 and a positioning component 2;

[0023] The worktable 1 has a positioning post 11 in the middle, and the worktable 1 has one or more positioning elements 2 arranged opposite to each other; for example Figure 3As shown, the worktable 1 is equipped with a guide rail assembly 13. The positioning element 2 is connected to the worktable 1 through the guide rail assembly 13, and the positioning element 2 is detachably connected to the worktable 1 through fasteners 14. The guide rail assembly 13 is an existing rail and slider assembly. The positioning element 2 is connected through the slider rail. The guide rail assembly 13 serves to limit and connect, facilitating the adjustment of the position of each positioning element 2 as needed. The fasteners 14 facilitate the positioning and movement of the positioning element 2, preventing the positioning element 2 from sliding during positioning.

[0024] The positioning component 2 includes a base 21, an adjusting component 22, a moving block 23, a connecting seat 24, a positioning plate 25, and a roller 26. The adjusting component 22 is connected to the moving block 23 via the base 21. The moving block 23 has an upward inclined surface 231 facing the positioning plate 25. The middle part of the positioning plate 25 is hinged to the connecting seat 24, which is located on the base 21. The roller 26 is located at one end of the positioning plate 25, above the inclined surface 231. The bottom of the other end of the positioning plate 25 has an arc-shaped protrusion 251.

[0025] This utility model discloses a positioning fixture for flange processing. The positioning element 2 is pushed away from the positioning post 11 to prevent the positioning plate 25 from interfering with the flange. The flange to be processed is then placed on the positioning post 11. The positioning element 2 moves to a suitable distance from the flange. The adjusting element 22 is operated to push the moving block 23 towards the positioning plate 25. The positioning plate 25 rotates along the inclined surface 231 of the moving block 23, and the end of the positioning plate 25 presses the flange onto the worktable 1 to prevent the flange from rotating during processing. After processing is completed, the adjusting element 22 is operated to push the moving block 23 away from the positioning plate 25, and the positioning element 2 is completely removed from the flange, facilitating the removal of the flange.

[0026] The outer wall of the positioning post 11 is provided with a sealing ring 12. The sealing ring 12 can reduce the gap between the inner hole of the flange and the positioning post 11, and further reduce the possibility of the flange loosening and shifting during processing.

[0027] The roller 26 replaces the positioning plate 25 and contacts the inclined surface 231 of the moving block 23 to achieve rolling friction, making the rotation of the positioning plate 25 smoother. The surface of the roller 26 is provided with a rubber layer 261, which can increase the friction between the roller 26 and the inclined surface 231 and prevent the roller 26 from slipping on the inclined surface 231.

[0028] The arc-shaped protrusion 251 at the end of the positioning plate 25 can increase the pressure on the flange and improve the positioning ability of the flange. The arc-shaped protrusion 251 is provided with a rubber layer 252, which protects the contact area with the flange and prevents the flange from being scratched during positioning.

[0029] The adjusting component 22 is preferably a screw, and the base 21 is provided with a connecting plate 27. The adjusting component 22 is threadedly connected to the connecting plate 27, and the end of the adjusting component 22 is rotatably connected to the moving block 23.
