Stainless steel flange drilling equipment

The utility model relates to the technical field of machining, in particular to stainless steel flange drilling equipment, which is characterized in that a plurality of groups of flange plates are put into a storage barrel from a feed port of the storage barrel, a lifting platform extends into a limiting barrel through extension of a first hydraulic cylinder, and then the lifting platform extends into the limiting barrel through extension of an air cylinder; a pushing plate discharges a group of flange plates into a limiting barrel through a feeding square pipe, the group of flange plates fall at the top end of a lifting table, then an air cylinder shrinks and resets, and a first hydraulic cylinder stretches, so that the lifting table is matched with the top of the limiting barrel to fix the flange plates in the limiting barrel; then drilling is conducted on the flange plate in the limiting barrel through the drilling device, then the first hydraulic cylinder shrinks and resets, the flange plate at the top en
