The operation mode is that firstly, a through hole is formed in the square steel, the welding square nut is placed into a welding position through the projection welding nut mounting through hole, and the ejector rod of the nut welding machine stretches into the square steel beam through the projection welding nut mounting through hole, so that the welding square nut is welded to the square steel beam. In order to ensure that a standard part is smoothly put into the through hole from the installation of the projection welding nut in the operation process of workers and ensure that the ejector rod of the nut welding machine can smoothly penetrate through the hole to realize nut welding, the diameter D1 of the general through hole is more than 30 mm. Taking the section size D2 of the section steel commonly used on the vehicle frame as an example of 40mm, after the nut is drilled, the section material is only left with D2-D1 being 10mm, which is unfavorable for the strength of the square steel beam and difficult to operate.
In addition, holes in the section steel are generally formed by laser cutting. In a traditional nut welding mode, a nut mounting hole and a projection welding nut mounting through hole are required to be formed in one nut. This solution is costly due to the long length of the laser cutting line.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the difficult problem of welding projection nut on the square steel beam. In order to solve the problem of traditional structure nut welding difficulty, the utility model discloses a design general nut plate structure, reduce the quantity in hole on the square steel roof beam, need not open the welding via hole in the opposite side of welding square nut, and have the nut board to strengthen at nut mounted position, the intensity and the mounting point intensity of square steel roof beam are high, have saved the cost simultaneously.
The utility model provides a fuel cell hydrogen energy commercial car shaped steel frame welding square nut mounting structure, includes: the method comprises the following steps of nut via holes, welding square nuts, square steel beams and nut plates;
the welded square nut is welded on the nut plate through a nut welding machine to form a nut plate assembly, and the nut plate assembly is connected with the square steel beam through welding;
the nut via hole is located at the edge of an opening at the upper end of the square steel beam.
Furthermore, the nut plate is a small stamping part, a universal design is adopted, and the part cost is low.
Further, the nut via hole on the square steel beam is finished through laser cutting, and the distance between the nut via hole and the edge of the welded square nut is not less than 2 mm.
Furthermore, one end of the welding square nut is provided with four welding contact angles and is welded with the nut plate; the other end is a flat and smooth plane and faces the inner side of the square steel beam.
Furthermore, the square steel beam is hollow rectangular steel, and the specific shape can be designed by oneself.
Be different from traditional prior art, the utility model discloses at first with welding square nut through the nut welding machine weld to the nut plate on, form the nut plate assembly, then be connected nut plate assembly and square steel roof beam through the welding machine.
The utility model discloses need not open projection welding nut installation via hole, consequently the limited reduction of laser cutting length has reduced the laser cutting cost.
The utility model discloses need not fill in welding square nut from projection nut installation via hole, but weld welding square nut and nut plate in advance and form the nut plate assembly, weld the nut plate assembly on the square girder steel again at last, therefore easy operation.
The utility model provides a beneficial effect that technical scheme brought is:
(1) a universal nut plate structure is designed, so that the problem that the conventional nut is difficult to weld is solved;
(2) the number of holes in the square steel beam is reduced, the length of the laser cutting line of the profile steel can be effectively reduced, and the laser cutting cost is saved;
(3) the welding through hole does not need to be opened in the other side of welding square nut, and there is the nut board to strengthen at nut assembly position, and the intensity and the mounting point intensity of square steel beam are high.
