Integrated hole making method for quick-release opening cover

The invention discloses an integrated hole making method for a quick-release mouth cover. A process gasket is arranged between the opening cover and a skeleton structure, a knife edge outlet surface of the upper layer opening cover is attached to the process gasket to ensure that in hole making, no burr or delamination is generated; at the same time, holes are made in the opening cover and the skeleton structure; and during the hole making process, an over-sized depth limiter is used to simultaneously treat the holes with different diameters of the upper opening cover and a lower frame structure. The integrated hole making method effectively avoids the phenomenon of hole misalignment phenomenon that the diameters of the holes in the opening cover and the skeleton structure are not coaxialthrough the arrangement of the process gasket, improves the uniformity of hole making by simultaneously making the holes in the opening cover and the skeleton structure, reduces the hole misalignmentand errors of the hole dia
