The invention discloses rotary friction welding equipment for aviation alloy pipe butt joint, which comprises a son pipe, a mother pipe, a base, a butt joint cylinder, a fixing device, a driving device, a jacking device and a butt joint piece, the fixing device comprises an inserting sleeve, a clamping seat, a moving sleeve and a butt joint head, and the driving device comprises a servo driving motor and a driven gear. The jacking device comprises a servo jacking motor and a fixing sleeve, the child pipe and the mother pipe are fixed through the fixing devices on the left side and the right side, the head of the child pipe and the head of the mother pipe stretch into the butt joint cylinder, the child pipe is driven by the driving device to rotate, the mother pipe is driven by the jacking device to move leftwards, and therefore rotary butt welding of the child pipe and the mother pipe is achieved. The fixing device has the beneficial effects that circumferential multi-point type centering fixing can be achiev
