[0018] As Figures 1 to 3 shown, a fixture for machining a flange proposed by the utility model includes a workbench, a placement table 2, a driving rod 404, and an abutting seat 5; a driving mechanism is arranged inside the workbench, and multiple output ends of the driving mechanism extend to the outside of the workbench; the placement table 2 is installed in the middle of the top end of the workbench; multiple groups of driving rods 404 are provided, and the multiple groups of driving rods 404 are evenly distributed on the multiple output ends of the driving mechanism, and the top end of the driving rod 404 is slidably connected to the top end of the workbench; the abutting seat 5 is installed at the top end of the driving rod 404, and the abutting seat 5 is in abutting connection with the flange placed on the placement table 2.

[0019] Furthermore, the workbench is composed of a stable base 1, a support cylinder 101 installed at the top end of the stable base 1, and a shielding top seat 102 detachably installed at the top end of the support cylinder 101 through bolts. The driving mechanism is arranged inside the support cylinder 101, and the driving rod 404 is slidably connected to the shielding top seat 102.

[0020] Furthermore, the driving mechanism includes a driving bevel gear 4 and a threaded rod 402; the driving bevel gear 4 is driven to rotate by a motor installed inside the support cylinder 101; multiple groups of threaded rods 402 are provided, the threaded rods 402 are rotatably connected to the support cylinder 101, the multiple groups of threaded rods 402 are evenly distributed on the support cylinder 101, one end of the threaded rod 402 extends into the support cylinder 101 and is installed with a driven bevel gear 401, the driven bevel gear 401 is meshed and connected with the driving bevel gear 4, and the other end of the threaded rod 402 extends to the outside of the support cylinder 101 and is threadedly connected with a sliding cylinder 403, and the other end of the sliding cylinder 403 is connected to the driving rod 404.

[0021] Furthermore, multiple groups of guiding seats 3 are evenly installed at the top end of the shielding top seat 102.
