The locking fasteners 400 are used to cooperate with the front support plates 200 and the rear support plates 300 to clamp the welded parts.
[0038] The welding process apparatus for frame-type thin-walled structures provided in this embodiment places the welding parts on the body 100 and positions them with the positioning mandrel 301 and positioning pin 201. Then, the welding parts are clamped by the locking fastener 400.

It reduces deformation during the welding process, can better achieve the required welding dimensions of the product, improve the welding accuracy of the product, and has a simple structure and is easy to use. Compared with traditional welding methods, it has the advantages of low cost and high reliability.
[0039] Optionally, the main body 100 is also symmetrically provided with a pair of middle support plates 500, and the middle support plates 500 are located between the front support plate 200 and the rear support plate 300. In this way, the middle support plate 500 cooperates with the front support plate 200 and the rear support plate 300 to comprehensively position and fix the welded parts, which can make the placement of the welded parts more stable, avoid the displacement and deformation of the welded parts, ensure the stability of welding, and improve welding accuracy.
[0040] Optionally, the line connecting the two rear support plates 300 and the two middle support plates 500 closest to the same side of the main body 100 is parallel to the horizontal midline of the main body 100. This makes the installation positions of the pair of rear support plates 300 and the pair of middle support plates 500 more neat, so as to more stably fix the welded parts, effectively prevent the welded parts from shifting or deforming, and improve the stability of fixing the welded parts.
[0041] Optionally, a positioning plate 202 is also provided on the front support frame 200. In this way, the positioning plate 202 can realize multi-size positioning function, which can better realize the welding dimensions required by the product and improve the welding quality.
[0042] Optionally, multiple positioning inserts 202 and positioning pins 201 are provided along the height direction of the front support frame 200. In this way, the welding parts can be positioned and fixed at different positions according to the welding fixing requirements, thus meeting diverse positioning needs.
[0043] Optionally, both the positioning plate 202 and the positioning pin 201 are detachably connected to the front support frame 200. This allows the positioning plate 202 and the positioning pin 201 to be detachable, without affecting the removal of the welded parts, making the process convenient and quick.
[0044] Optionally, the main body 100 is provided with multiple support seats 600, and the multiple support seats 600 are all located between the pairs of front support plate frames 200 and the pairs of rear support plate frames 300.

[0045] Optionally, four support bases 600 are provided, two of which are located on one side between the paired middle support plates 500, and the other two are located on one side between the paired rear support plates 300. In this way, the four support bases 600 are used to support and fix the base plate of the welded part, further enhancing the stability of the welded part.
[0046] Optionally, a limiting hole 601 is provided on the top of the support base 600, and a limiting post 602 is movably disposed in the limiting hole 601. In this way, the limiting hole 601 on the support base 600, in cooperation with the limiting post 602, ensures the horizontal positioning dimension of the base plate during welding, which can better achieve the welding dimensions required by the product and improve the accuracy of the product after welding.
[0047] Optionally, the limiting hole 601 is a threaded hole, and the limiting post 602 is threadedly connected to the support base 600 through the threaded hole.

The vertical plate 401 is mounted on the body 100, and the locking bolt 402 is mounted on the vertical plate 401 and threadedly connected to it. Thus, by rotating the locking bolt 402, it moves towards the welded part, clamping it and controlling the dimensions of the welded parts on both sides of the welded rear end, thereby improving welding quality.
[0049] Optionally, a locking fastener 400 is provided at the position of each pair of rear support plates 300 and each pair of middle support plates 500 near the body 100. In this way, different positions of the welded parts can be locked and fixed, making the placement of the welded parts more stable and avoiding dimensional deviations caused by displacement of the welded parts, which would affect the welding quality.
[0050] Optionally, multiple threaded holes are evenly provided along the height of the upright plate 401, and the locking bolt 402 is connected to one of the threaded holes. In this way, by removing the locking bolt 402 and inserting it into the threaded holes at different positions, it is easy to adjust the clamping and fixing position of the welded parts, so as to better fix the welded parts and meet diverse usage needs.
[0051] Optionally, both the front support frame 200 and the rear support frame 300 are connected to the main body 100 via stiffening plates 700. In this way, the stiffening plate 700 structure features light weight, high load-bearing capacity, strong bending resistance, and small space occupation. Connecting the front support frame 200 and the rear support frame 300 to the main body 100 using the stiffening plates 700 provides support, protection, and structural connection, thereby making the installation of the front support frame 200 and the rear support frame 300 more secure and stable.
[0052] Optionally, the stiffening plate 700 is located on one side of the front support plate 200 and the rear support plate facing the horizontal center line of the body 100. This reduces the impact on the welding process and avoids hindering the placement and installation of welded parts.
[0053] Optionally, the body 100 has a rectangular structure. This makes the structure of the body 100 more regular and neat, so that the welding parts can be placed neatly on the body 100, avoiding the situation where the welding quality is affected by the tilting of the welding parts.
[0054] Optionally, a fixing screw is provided at each corner of the body 100. This makes the body 100 more stable, prevents the body 100 from shifting, and further ensures the stability and safety of the welding.
[0055] Optionally, the mounting surface of the body 100 is uniformly provided with anti-slip textures. This increases the friction between the body 100 and the welding parts, making the welding parts more stable on the body 100, preventing the welding parts from shifting under external forces, further improving the stability of the welding parts and ensuring welding quality.
