Flange cylinder circumferential synchronous rapid assembly tool

The invention provides a circumferential synchronous and rapid assembly tool for a flange cylinder, which ensures circumferential synchronous and rapid assembly and locking of the flange cylinder and effectively improves the assembly efficiency. Comprising an annular base plate which is arranged on an assembly table body and can rotate, a special-shaped hole is formed in the annular base plate along the circumference, the special-shaped hole comprises a large hole end and a small hole end which are communicated, and the annular base plate and a flange cylinder are connected through a sliding connecting piece. The sliding connecting piece comprises a large sliding part at the lower end and a small sliding part located at the upper end of the large sliding part. A rotary driving mechanism is arranged between the assembly table body and the annular base plate, when the rotary driving mechanism drives the annular base plate to rotate, the large sliding part slides in the space below the special-shaped hole, and t
