The invention discloses a method for machining a thin-wall square pipe through hollow thin-wall pipe fitting screwing equipment. The hollow thin-wall pipe fitting screwing equipment comprises a motor,a reducer, a chuck, a lower clamping mechanism, a lower plug mechanism and a sand filling device. The reducer is connected with a first connecting plate, the first connecting plate is connected witha second connecting plate through connecting rods, and the chuck is fixedly arranged on the lower surface of the second connecting plate. A first lifting frame and a second lifting frame are arrangedon a polished shaft and a lead screw of a vertical type rack, the lower clamping mechanism is fixedly arranged on the first lifting frame, and the lower plug mechanism is fixedly arranged on the second lifting frame. The sand filling device comprises a funnel, a sand storing tank and a hose, the funnel is slidably connected on the connecting rods between the first connecting plate and the second connecting plate through sli
