[0047] The assembly method of the outward-turned flange combined structure tooling for electromagnetic shielding:

[0048] First, adjust the first limiting portion 5 on the inner side of the flange adapter ring 3 and the inner wall mating surface of the flange cylinder 1 to ensure that the first limiting portion 5 and the flange cylinder 1 mating surface are aligned and installed, and then adjust the four second positioning pin holes 8 on the flange adapter ring 3 so that the flange adapter ring 3 and the first positioning pin holes 7 on the flange adapter plate 2 are at the same position, insert four positioning pins 9 connected to the flange adapter plate 2 for positioning, and after positioning, use the locking parts 12 and spring washers to fix the flange adapter ring 3 and the flange adapter plate 2, and complete the combined installation after tightening to form an outward-turned flange combined structure tooling for electromagnetic shielding; finally, adjust the outward-turned flange combined structure tooling for electromagnetic shielding to align with the product hole position, install the locking parts 12 and spring washers, and tighten them to complete the combined installation.
