This application relates to an assembly fixture for step shafts, belonging to the technical field of escalator assembly. It includes a base plate, radial positioning seats, and axial positioning seats. Multiple radial positioning seats are spaced apart along the length of the base plate, and the step shaft is placed on these radial positioning seats along its length. Two axial positioning seats are located at opposite ends of the step shaft along its length and are fixedly mounted on the base plate. During assembly, the operator places the step shaft on the radial positioning seats, achieving radial restraint. At this time, both ends of the step shaft along its length abut against the two axial positioning seats. The axial positioning seats are equipped with locking elements to lock the step shaft and prevent rotation. This application, through the synergistic effect of the radial and axial positioning seats, forms a stable constraint on the step shaft radially and axially, preventing the step shaft from shifting or moving due to external forces or vibrations during assembly.
