And the large side beam assembly 700 is moved and positioned by the axial positioning and moving mechanism 500, so that the heavy operation of manually carrying the side beam assembly 700 is avoided, and the positioning of the side beam assembly 700 and the cross beam assembly 600 is more accurate. Meanwhile, by using the assembly tool for the steering frame provided by the embodiment of the invention, the assembly of the beam assembly 600, the side beam assembly 700 and the frame can be forward or backward, and the overturning operation of the beam assembly 600 and the side beam assembly 700 in the assembly process is reduced.

S200, the side beam 710, the craft piece 720 and the side beam accessory are obtained, the craft piece 720 is fixedly connected to a preset position on the side beam 710 (the preset position can be guaranteed through scribing or tooling), the craft piece 720 has a step-shaped structure, and the step-shaped structure is provided with a first craft plane 7211, a second positioning vertical surface 7212 and a second craft plane 7213. The second positioning riser 7212 is connected 7213 to the first and second process planes 7211 and 7213, respectively, although the second positioning riser 7212 is configured to be positioned in abutment with the first positioning riser 432 of the axial positioning member 430. The side beam 710 is positioned and clamped on the side beam assembling mechanism 400, and is assembled by using the side beam assembling tool to obtain the side beam assembly 700.

S300, the axial positioning and moving mechanism 500 is used for driving the side beam assembling mechanism 400 to move axially along the cross beam, so that the cross beam is inserted into the insertion hole of the side beam 710, and the side beam assembly 700 is moved and positioned to a preset installation position relative to the cross beam assembly 600; the side beam assembly 700 and the cross beam assembly 600 are assembled to be connected to obtain a primary bogie frame. At this time, the connected side and cross beam assemblies 700 and 600 are not final bogie frames but primary bogie frames because the craft 720 with the stepped structure does not meet the drawing requirements and needs further processing.

S300, the primary bogie frame is taken down from the bogie frame assembly tool in the invention, the craft piece 720 is processed to remove the step structure, and the craft piece 720 'with the step structure removed is obtained (at this time, the shape and the structure of the craft piece 720' with the step structure removed meet the requirements of a drawing, the size of the craft piece 720 is large, and the craft piece is mainly used for axial positioning of a cross beam), and the final bogie frame is obtained.

Compared with the prior art, the steering frame assembly method provided by the embodiment of the invention has the advantages that the positioning and the assembly of the beam assembly and the side beam assembly are realized by arranging the beam following clamping mechanism for positioning and clamping the beam assembly and the side beam assembly mechanism for positioning and clamping the side beam assembly, and by arranging the positioning assembly for positioning the beam following clamping mechanism and the axial positioning moving mechanism for driving the side beam assembly mechanism to move and positioning the side beam assembly to the preset mounting position relative to the beam assembly, so that the complicated manual scribing positioning and the complicated and heavy carrying operation are avoided; meanwhile, by arranging the process piece on the side beam and using the process piece for axial positioning of the cross beam, the method is more accurate than the method using the shaping and correcting surface for positioning in the prior art.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
