Air tightness detection equipment for aluminum alloy hub processing

The invention discloses air tightness detection equipment for aluminum alloy hub processing, and relates to the technical field of hub air tightness, the air tightness detection equipment comprises a supporting seat, the front side of the supporting seat is fixedly connected with a fixing plate, the side walls of the upper end and the lower end of the fixing plate are fixedly connected with air cylinders, and the telescopic ends of the two air cylinders are fixedly connected with connecting plates; the side walls of the opposite ends of the two connecting plates are symmetrically and fixedly connected with two fixing columns, and one ends of the two fixing columns are fixedly connected with arc-shaped sealing shells. According to the invention, the gap of the contact part of the hub surface and the tire can be accurately detected, and a worker can visually judge the size of the gap of the contact part of the hub surface and the tire by observing the lifting height of the detection feedback boss, so that the l
