The invention discloses a self-centering lifting machine of a tire balancing machine. The self-centering lifting machine comprises a rack, a movable seat assembly, a driving part and a centering mechanism, the movable seat assembly drives the rack to move in the axial direction of the balance shaft. The driving part comprises a speed reducer arranged on the rack, a power source arranged on the speed reducer, an upper lead screw assembly and a lower lead screw assembly, wherein the upper lead screw assembly and the lower lead screw assembly are arranged on the upper side and the lower side of the speed reducer, and the power source synchronously drives the upper lead screw assembly and the lower lead screw assembly through the speed reducer. The centering mechanism comprises an upper centering component connected with the upper screw rod assembly and a lower centering component connected with the lower screw rod assembly, and the upper centering component and the lower centering component synchronously move in opposite directions in the vertical direction; the lower centering component lifts the tire, and the axis of the tire and the axis of the balance shaft are parallel and located in the same vertical plane. The upper centering part limits the height of the tire after making contact with the tire tread, and the circle centers of tires of different sizes are located to be coaxial with the balance shaft. Tyres of different sizes can be quickly and conveniently positioned and mounted on the balance shaft, and the mounting efficiency is improved.
