In step S1, the left end cap locating pin 23 is inserted into the first locating sleeve 423, so as to limit the position of the left end cap 2 of the steering support in the Y direction and Z direction of the vehicle, then the left end of the steering support tube beam 1 is inserted into the hole of the left end cap, and the clamp locating pin 432 is inserted into the tube beam locating hole, so as to prevent the steering support tube beam 1 from rotating, and meanwhile, the right end of the steering support tube beam 1 abuts against the limit stop 433, so as to ensure the position of the steering support tube beam 1 in the Y direction of the vehicle is accurate, the first tube beam clamping unit 431 can play an auxiliary supporting role, then the left end cap 2 of the steering support is clamped and located by the first locating unit 421 and the second locating unit 422, so as to limit the position of the left end cap 2 of the steering support in the X direction of the vehicle, and finally, the instrument panel left side bracket 4, the left side steering column mounting bracket 5, the right side column mounting bracket 6 and the instrument panel middle bracket 7 are respectively welded to the steering support 1, thereby completing the manufacture of the first sequence welding assembly.
The positioning structure of the left side of the first-stage welded block in step S2 is equivalent to welding the steering support right end cap 3 with respect to the steering support left end cap 2 on the first-stage welded block by using the first left positioning mechanism 42 in step S1. In step S2, the right end of the steering support pipe beam 1 of the first-order welded assembly is inserted into the right end cover central hole, the right end cover positioning pin 33 is inserted into the second positioning sleeve 523, so that the positions of the steering support right end cover 3 in the Y direction and the Z direction of the automobile can be limited, the steering support left end cover 2 on the first-order welded assembly is clamped and positioned by the first left positioning mechanism 42 arranged on the second base 51, so that the positioning of the steering support left end cover 2 and the steering support pipe beam 1 is realized, the steering support right end cover 3 is clamped and positioned by the sixth positioning unit 521 and the seventh positioning unit 522, so that the position of the steering support right end cover 3 in the X direction of the automobile can be limited, so that the relative positions of the steering support left end cover 2, the steering support pipe beam 1 and the steering support right end cover 3 are ensured to be correct, the platen support 8, the first floor connecting support 9, the second floor connecting support 10, the first steering shaft mounting support 11 and the second steering shaft mounting support 12 are matched with the corresponding positioning units, and the steering support pipe assembly is welded to the second-order welded assembly, and the second steering support pipe assembly is manufactured.

In the step S1, the steering support left end cover 2, the instrument panel left side support 4, the left side steering column upper mounting support 5, the right side steering column upper mounting support 6 and the instrument panel middle support 7 are welded to the steering support tubular beam 1, so that accurate positioning of the steering support left end cover 2 and the steering support tubular beam 1 can be realized, meanwhile, the left side steering column upper mounting support 5 is adjacent to the right side steering column upper mounting support 6, the instrument panel left side support 4 and the instrument panel middle support 7 are staggered by nearly 180 degrees in the circumferential direction of the steering support tubular beam 1 relative to the left side steering column upper mounting support 5, heating is approximately distributed on two symmetrical sides of the steering support tubular beam 1 during welding, and the situation that the steering support tubular beam 1 is heated on one side during welding can be avoided, so that deformation of the steering support tubular beam 1 is reduced. When the bedplate support 8, the first floor connecting support 9, the second floor connecting support 10, the first steering shaft mounting support 11 and the second steering shaft mounting support 12 are welded in the step S2, welding seams of the supports are welded around the circumferential direction of the steering support tubular beam 1, the steering support tubular beam 1 is heated uniformly during welding, and the welding deformation is small.
