[0035] Example 1

[0036] like Figure 1-4 As shown, the laser welding machine proposed in this utility model includes a machine body 1, a laser welding gun 6, a second electric slide rail 8, a mounting assembly, and a lifting assembly;

[0037] The mounting component is located at the top center of the body 1, and the bottom of the mounting component is provided with a rotating component for rotating the mounting component on the body 1 in the use state.

[0038] The second electric slide rail 8 is installed on the top of the body 1 and is arranged facing the front of the body 1. The slider of the second electric slide rail 8 is provided with an adjustment component for adjusting the orientation of the laser welding gun 6 in use.

[0039] The lifting assembly is mounted on the side of the adjusting assembly and connected to the laser welding gun 6.

[0040] In this embodiment, the fixture is positioned and installed using the mounting component, and the stainless steel product is fixed to the mounting component by the fixture. The adjustment component is driven to move by the second electric slide rail 8, which in turn drives the laser welding gun 6 to move along the length of the second electric slide rail 8 via the lifting component. This moves the laser welding gun 6 to the position on the stainless steel product to be welded, and the height of the laser welding gun 6 is adjusted by the lifting component. At the same time, the second electric slide rail 8 drives the laser welding gun 6 to continue moving, allowing the laser welding gun 6 to perform welding on the stainless steel product. Simultaneously, the adjustment component adjusts the angle of the lifting component, which in turn adjusts the angle of the laser welding gun 6, allowing the lifting component to drive the laser welding gun 6 to weld the side of the stainless steel product. At the same time, the mounting component is rotated by the rotating component, allowing the laser welding gun 6 to cover the welding area in all directions. This makes the welding process of the stainless steel product efficient and precise, meeting the welding requirements of different angles and positions, and improving the welding efficiency and production efficiency of stainless steel products.

[0041] Example 2

[0042] like Figure 2 As shown, the laser welding machine proposed in this utility model differs from the first embodiment in that the mounting components include a first electric slide rail 2, a mounting plate 3, and a connecting plate 5.

[0043] The connecting plate 5 is located on the upper middle part of the body 1 and is movably connected to the body 1;

[0044] The first electric slide rail 2 is installed on the top of the connecting plate 5 and arranged along the length of the connecting plate 5. The first electric slide rail 2 is existing technology and will not be described in detail here.

[0045] Mounting plate 3 is installed on the top of the slider of the first electric slide rail 2.

[0046] In an optional embodiment, the upper surface of the mounting plate 3 is provided with a plurality of threaded holes 4, which are arranged at equal intervals to install the fixture during use.

[0047] In an optional embodiment, the length of the second electric slide rail 8 is greater than the length of the first electric slide rail 2, for use in enabling the laser welding gun 6 to perform welding work on stainless steel products at the end of the first electric slide rail 2.

[0048] In this embodiment, by providing multiple threaded holes 4 on the end face of the mounting plate 3, the fixture is ensured to be installed securely. The mounting plate 3 is driven to move along the length direction of the first electric slide rail 2 on the connecting plate 5, so that the mounting plate 3 drives the fixture and stainless steel products to adjust their positions, and the laser welding gun 6 is precisely aligned with the welding point of the stainless steel products to achieve efficient welding.

[0049] Example 3

[0050] like Figure 2 As shown, the laser welding machine proposed in this utility model differs from Embodiment 1 in that the rotating assembly includes a second motor 11 and a rotating shaft 13.

[0051] The rotating shaft 13 is installed at the bottom center of the connecting plate 5 and extends to the bottom of the body 1;

[0052] The second motor 11 is installed at the bottom of the body 1 and connected to the rotating shaft 13 via a coupling.

[0053] In this embodiment, the two ends of the rotating shaft 13 are connected to the connecting plate 5 and the output shaft of the second motor 11 respectively, so that when the second motor 11 starts, it drives the connecting plate 5 to rotate above the machine body 1 through the rotating shaft 13, and causes the workpiece to rotate on the machine body 1, thereby realizing multi-angle welding of stainless steel products.

[0054] Example 4

[0055] like Figure 4 As shown, the laser welding machine proposed in this utility model differs from Embodiment 1 in that the adjustment component includes a first motor 10, a gear 12, a connecting rod 14, and a fixing plate 15.

[0056] The first motor 10 is mounted on the top of the slider of the second electric slide rail 8 and is arranged facing the front of the machine body 1;

[0057] The fixing plate 15 is installed on the side of the slider of the second electric slide rail 8;

[0058] The connecting rod 14 is rotatably installed in the middle of the fixed plate 15. The figure is only for illustration. When in use, a T-shaped connecting rod 14 can be selected. During installation, the T-shaped end of the connecting rod 14 is placed between the fixed plate 15 and the second electric slide rail 8 to prevent the connecting rod 14 from falling off the fixed plate 15.

[0059] There are two gears 12, which mesh with each other and are respectively connected to the output shaft of the first motor 10 and the connecting rod 14.

[0060] In this embodiment, the gear 12 on the side of the second electric slide rail 8 is connected to the lifting assembly, so that when the first motor 10 starts, it drives the gear 12 on the output shaft to rotate. The two gears 12 mesh with each other, so that the gear 12 on the side of the second electric slide rail 8 rotates on the fixed plate 15 through the connecting rod 14, and the gear 12 drives the lifting assembly to rotate, so that the lifting assembly drives the laser welding gun 6 to adjust the angle, so that the laser welding gun 6 can perform welding work on the side of the stainless steel product.

[0061] Example 5

[0062] like Figure 3 As shown, the laser welding machine proposed in this utility model differs from Embodiment 1 in that the lifting assembly includes a telescopic rod 9 and a sleeve 7.

[0063] The telescopic rod 9 is installed on the side of the gear 12;

[0064] The sleeve 7 is installed at the bottom end of the telescopic rod 9 and sleeved on the outside of the laser welding gun 6.

[0065] In an optional embodiment, the length of the telescopic rod 9 is greater than the outer dimension of the gear 12.

[0066] In this embodiment, by inserting the laser welding gun 6 into the sleeve 7 and fixing the laser welding gun 6 to the sleeve 7 with bolts, the stability of the laser welding gun 6 during the welding process is ensured. At the same time, through the fine adjustment of the telescopic rod 9, the laser welding gun 6 can move flexibly in multi-dimensional space to achieve all-round welding coverage.

[0067] In this invention, multiple threaded holes 4 are provided on the end face of the mounting plate 3 to install the clamp and fix the stainless steel product onto the clamp. Simultaneously, the second electric slide rail 8 drives the fixed plate 15 to move, causing the fixed plate 15 to move the telescopic rod 9 laterally via the engagement of the connecting rod 14 and the gear 12. The telescopic rod 9 then moves the laser welding gun 6 to the welding position through the sleeve 7. When the first motor 10 starts, it drives the gear 12 on the output shaft to rotate. The two gears 12 mesh with each other, causing the gear 12 on the side of the second electric slide rail 8 to rotate on the fixed plate 15 via the connecting rod 14. Gear 12 drives telescopic rod 9 to rotate, thereby adjusting the angle of laser welding gun 6. At the same time, the second electric slide rail 8 cooperates with telescopic rod 9 to enable laser welding gun 6 to weld the sides and top of stainless steel products. When the second motor 11 is started, it drives connecting plate 5 to rotate above machine body 1 through rotating shaft 13, causing stainless steel products to rotate on machine body 1. Simultaneously, the first electric slide rail 2 drives mounting plate 3 to move laterally, so that the side of stainless steel product is aligned with the position of laser welding gun 6, allowing laser welding gun 6 to weld multiple sides of stainless steel products, thereby improving welding efficiency and production efficiency.
