[0002] In today's manufacturing industry, welding technology is indispensable for the production of various products, especially for the welding of shell-type components. Traditional welding equipment struggles to provide stable support for irregularly shaped shell-type components across multiple dimensions and points. Due to the irregular shape of the shell components, they are prone to displacement during the welding process due to unstable support, leading to increased welding errors and compromised welding precision. This not only affects product quality but also results in a large number of defective products and increases production costs. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide an automatic welding machine for shell-type components, which solves the problems that traditional welding machines are mostly complex in design, high in cost, and inconvenient to operate, making it difficult to promote and apply them on a wide scale.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] Example 1:

[0019] like Figure 1As shown in Figure 4, this utility model provides the following technical solution: it includes an automatic welding machine body 1, a support frame 11 installed on the automatic welding machine body 1, a welding tray 12 for supporting the shell components installed on the support frame 11, an adjustment component 2, the adjustment component 2 includes a rotating ring 21, a support arc plate 22, a docking block 23 and a support frame 24, a support component 3, the support component 3 rotates outside the support frame 11 through the adjustment component 2, the support component 3 includes an upper bracket 31, a lower bracket 32, a slide 33, an upper slider 34 and a support rod 35, the upper slider 34 slides on the inner wall of the slide 33, the support rod 35 is threadedly connected to the outer wall with a nut, and a positioning component 4, the X-axis position of the slide 33 is fixed by an upper pressure plate 41, and the Y-axis position of the support rod 35 is fixed by the positioning component 4.

[0020] In this implementation scheme: The automatic welding machine body 1 is used for welding shell-type components. During use, the welding tray 12 is installed and fixed via the support frame 11. The welding tray 12 directly supports the welding area of ​​the shell-type component. The welding position is fixed with the help of clamps. The welding head on the automatic welding machine body 1 performs the welding process. However, when using irregular shell-type components, after the welding area is on the welding tray 12, part of the area is outside the welding tray 12. The support range of the welding tray 12 is limited. In this case, the outer shell-type component cannot be supported by the welding tray 12, and the irregular shape makes it difficult to support it. In this situation, the adjustment component 2 can be used to address the issue. The support assembly 3 can be supported and fixed. It can be mounted on the outer wall of the welding tray 12 via a rotating ring 21, with the welding tray 12 rotatably connected to the rotating ring 21. The support arc plate 22 is fixed on the support frame 11. The top of the support frame 24 is connected to the outer wall of the rotating ring 21, and the bottom is connected to the support arc plate 22 via a mating block 23. The mating block 23 is slidably connected to the outer wall of the support arc plate 22, allowing the rotating ring 21 to rotate. The mating block 23 and the support frame 24 can rotate synchronously, and the support assembly 3 mounted on one side of the support frame 24 can rotate synchronously with it, positioning the support assembly 3 below the shell-like component. It can then be supported and fixed to one side of the support frame 24 via an upper bracket 31 and a lower bracket 32. The upper slider 34 slides on the slide 33 slidably connected to the inner wall of the upper bracket 31. The positions of several slides 33 on the inner wall of the upper bracket 31 can be adjusted. Based on the position of the housing wall, after the slides 33 are adjusted to an appropriate position, the height of the support rods 35 slidably connected to the upper slider 34 can be adjusted up and down. This ensures that the top of the support rods 35 is supported on the bottom of the housing. The several support rods 35 can be adjusted according to the shape of the housing to provide stable support, thus ensuring that the housing components are stably supported on the automatic welding machine body 1. This prevents displacement of the housing components due to unstable support when welding on the welding tray 12, thereby ensuring accurate welding position. During position adjustment, the friction plate 331 slides on the upper bracket 31 and the lower bracket 32. The upper pressure plate 41 slides between the upper bracket 31 and the lower bracket 32, allowing it to press against the friction plate 331. This increases the pressure between the friction plate 331 and the upper and lower brackets, thus limiting its position. The lower pressure plate 42 slides at the bottom of the lower bracket 32. After the slide 33 is positioned, the upper slider 34, which is slidably connected to the inner wall of the lower bracket 32, corresponds vertically to the upper slider 34 above it and is connected by a sliding rod 342. The lower pressure plate 42 presses against the bottom of the lower slider 341, positioning it on the slide 33 and preventing it from sliding.The slide 33 slides on the inner walls of the upper bracket 31 and the lower bracket 32, and the upper slider 34 and the lower slider 341 slide on the inner wall of the slide 33. All these sliding connections are achieved through a concave groove and a protrusion engaging structure, preventing them from disengaging.

[0021] The rotating ring 21 is rotatably connected to the outer wall of the welding tray 12, and the supporting arc plate 22 is connected to the support frame 11 through the mounting rod 26. The rotating ring 21 rotates with the outer wall of the welding tray 12, so that it can rotate to adjust the position of the supporting component 3, so that it can be adjusted according to the area where the unwelded part of the shell component is located. The mounting rod 26 is used to support and fix the supporting arc plate 22 on the outside of the support frame 11, so that the supporting arc plate 22 can limit the position of the bottom of the support frame 24 through the connection between the mating block 23 and the bottom of the support frame 24.

[0022] One end of the docking block 23 is connected to the support frame 24. The upper bracket 31 and the lower bracket 32 ​​are detachably connected to one side of the support frame 24 by bolts. Two fasteners 25 are threaded on the docking block 23. The docking block 23, which is slidably connected to the outer wall of the support arc plate 22, enables the rotating ring 21 to rotate normally and supports the bottom of the support frame 24, so that the support frame 24 can remain stable and provide stable position support for the support component 3. After the docking block 23 slides, the position of the docking block 23 can be supported and limited by the fasteners 25.

[0023] The slide 33 is divided into upper and lower groups. A lower slide block 341 is slidably connected to the lower slide block 33. A slide rod 342 is installed on the lower slide block 341 and is slidably connected to the support rod 35. The slide 33 is divided into upper and lower groups, which slide on the inner walls of the upper support 31 and the lower support 32 respectively. The lower slide block 341 is slidably connected to the support rod 35 through the slide rod 342, so that when the upper slide block 34 and the support rod 35 are displaced, the lower slide block 341 and the slide rod 342 can be displaced synchronously. Thus, when the lower pressure plate 42 supports the bottom of the lower slide block 341, it can position the support rod 35 in the Y-axis position.

[0024] Friction plates 331 are installed at both ends of the slide 33. The friction plates 331 are in contact with the upper bracket 31 or the lower bracket 32. The upper pressure plate 41 corresponds to the friction plates 331. A telescopic rod 43 is installed between the two upper pressure plates 41. The friction plates 331 installed at both ends of the slide 33 can cooperate with the upper pressure plate 41, so that the friction between the friction plates 331 and the upper bracket 31 and the lower bracket 32 ​​can be squeezed by the upper pressure plate 41, so that the slide 33 is limited in the X-axis position. The telescopic rod 43 is used to adjust the length so that it can support the upper and lower pressure plates 41, so that the friction plates 331 are tightly attached to the upper bracket 31 and the lower bracket 32.

[0025] A mounting bracket 44 is installed at the bottom of the lower bracket 32. A bolt is installed in the center of the mounting bracket 44. The mounting bracket 44 is located below the lower pressure plate 42. The mounting bracket 44 is supported below the lower bracket 32. The height of the lower pressure plate 42 can be adjusted by the bolt installed in the center of the mounting bracket 44, so that the top of the lower pressure plate 42 is supported at the bottom of the lower slider 341.

[0026] The working principle of this technical solution is as follows: The shell-like component is placed on the welding tray 12 mounted on the support frame 11. The component position is initially adjusted so that the area to be welded is aligned with the working range of the welding head. If the edge or irregular area of ​​the component exceeds the support range of the welding tray 12, the rotating ring 21 is rotated, causing the support frame 24 and support assembly 3 to rotate as a whole, moving the support assembly 3 below the area to be supported on the component. The slide carriage 33 on the inner walls of the upper bracket 31 and lower bracket 32 ​​is slid, and the X-axis position of the slide carriage 33 is adjusted according to the bottom contour of the component. The upper pressure plate 4... 1. Press the friction plate 331 to fix the position of the slide 33 by friction. At the same time, adjust the sliding distance of the upper slider 34 on the inner wall of the slide 33 so that the support rod 35 is close to the bottom of the component. Rotate the nut on the outer wall of the support rod 35 to fix its height and ensure that the top of the support rod 35 is tightly attached to the component. For the upper and lower slides 33, the lower slider 341 and the support rod 35 are connected by the slide rod 342. Adjust the bolts of the mounting bracket 44 at the bottom of the lower support 32 so that the lower pressure plate 42 presses the lower slider 341 upward to complete the fixation of the support rod 35 in the Y-axis direction and ensure that the overall force of the component is balanced.
