The invention relates to the technical field of stamping dies, and discloses a method capable of rapidly fixing a stamping die. The method comprises the following steps that the die with an upper die and a lower die in a die assembly state is placed on a workbench, is roughly placed in the middle position and does not need to be accurately placed, the die can slide on the workbench, a motor drives a rotating shaft to rotate through a transmission mechanism, the rotating shaft drives a cam to rotate, the cam drives a top plate to move downwards, the top plate drives a telescopic column and a reset spring to contract, meanwhile, the top block is driven to move downwards, the top block drives a fixing plate to move downwards, the fixing plate drives a positioning column to move downwards, and through a chamfer below the positioning column, when the positioning column moves downwards to penetrate through the inner wall of the upper die, the whole die can be driven to conduct position adjustment, so that the die is moved to the center of the workbench; and after the die moves to a proper position, the upper die is fixed by two clamping plates, and the lower die is fixed by a clamping mechanism, so that the rapid fixation of the die is realized. According to the method, manual clamping and fixing of workers are not needed, and the clamping time can be greatly shortened.
