The invention discloses a double-station automatic clamping system for aluminum alloy wheel friction stir welding. The double-station automatic clamping system comprises a supporting assembly, a hub positioning and clamping assembly and a rim positioning and clamping assembly. The supporting assembly comprises a bottom table and a supporting body, and the hub positioning and clamping assembly andthe rim positioning and clamping assembly are symmetrically arranged on the two sides of the supporting body. The hub positioning and clamping assembly is arranged on the bottom table, and the rim positioning and clamping assembly is connected to one side of the supporting body through a driving mechanism in a sliding manner. The hub positioning and clamping assembly and the rim positioning and clamping assembly are oppositely arranged, and the rim positioning and clamping assembly moves vertically so as to achieve positioning of a hub and a rim. By means of the double-station automatic clamping system, a rotary table
