The invention discloses a clamping device for an aluminum bicycle rim. A rotary pull disc which can rise and fall and can also rotate around the axis is arranged on a base of the clamping device in a positioned mode. A plurality of swing connecting rods are connected to the periphery of the rotary pull disc in a pivoted mode at intervals. A tensioning support mold is connected to the other end of each swing connecting rod in a positioned and pivoted mode. The tensioning support molds can radially slide back and forth on the radial surface with the rotary pull disc as the center, and inward bevels which can right hook the aluminum bicycle rim are formed on the upper surfaces of the tensioning support molds. The rotary pull disc moves up and down to drive the swing connecting rods to generate angle differences, so that the tensioning support molds are pushed to move outwards or inwards, the purposes of clamping and releasing are achieved, and clamping of the aluminum bicycle rim is achieved through the inward b
