Flange machining equipment for vehicle heat exchange tube

The invention discloses vehicle heat exchange pipe flange machining equipment. All the first round rods are jointly connected with a switching part; and the second support frame is connected with an oil immersion component. During use, the first fixing blocks at different height positions are used for bearing the flange pieces at intervals, the two first round rods drive the flange pieces to rotate at the same time, and anti-corrosion oil on the surfaces of the flange pieces is thrown away thoroughly through centrifugal force, so that rapid oil immersion and rapid oil drainage of the multiple flange pieces are achieved at the same time; the third connecting block and parts on the third connecting block can be quickly disassembled to serve as a jig to be recycled in loading, oil immersion and unloading operation, so that assembly line work is achieved, efficiency is further improved, and during oil immersion, the phenomenon that a rotating flange piece collides with a first round rod at high frequency to be da
