[0033] Example:

[0034] See also Figure 1-5 , a sputter-proof stainless steel pipe welding device, comprising an operating table 1, a plurality of supporting legs 4 are fixedly connected to the bottom end of the operating table 1, a gantry 6 is fixedly connected to the top end of the operating table 1, an electric telescopic rod 7 is fixedly connected to the bottom end of the gantry 6, a laser welding head is fixedly connected to the output end of the electric telescopic rod 7, an anti-sputtering component 2 is provided at the output end of the electric telescopic rod 7, a rotating component 3 is provided at the top end of the operating table 1, and a stainless steel pipe 5 is provided above the rotating component 3;

[0035] The anti-splashing assembly 2 includes an anti-splashing plate 21 fixedly connected to the output end of the electric telescopic rod 7 . A through hole 26 is formed at the top of the anti-splashing plate 21 . The output end of the electric telescopic rod 7 passes through the through hole 26 and extends to the inside of the anti-splashing plate 21 .

[0036] The anti-sputtering stainless steel pipe welding device of this scheme is mainly used to protect the workpiece, improve the welding quality, reduce the cleaning work, protect the operators and improve the work efficiency. Through the telescopic function of the electric telescopic rod 7, the position of the laser welding head can be accurately controlled, so as to perform high-quality welding in various complex environments. The anti-sputtering component 2 is used to prevent the sparks generated during welding from splashing and causing harm to the workers. The rotating component 3 is used to reduce the friction generated when the stainless steel pipe 5 is rotated.

[0037] See also Figure 4 A slide groove 22 is provided inside the splash shield 21, and the slide groove 22 is connected to the outside.

[0038] See also Figure 4 A rectangular frame 24 is slidably connected inside the slide groove 22, and a plurality of springs 23 are fixedly connected between the rectangular frame 24 and the inner wall of the slide groove 22. A rectangular groove 27 is opened at the outer end of the splash guard 21, and the rectangular groove 27 is connected to the slide groove 22. A pull rod 28 is slidably connected to the inner wall of the rectangular groove 27, and the pull rod 28 is fixedly connected to the rectangular frame 24.

[0039] The rectangular groove 27 of the present invention is used to limit the moving trajectory of the pull rod 28. When the stainless steel tube 5 needs to be welded, the stainless steel tube 5 is first placed above the roller 33, and then the electric telescopic rod 7 is controlled to extend. Since the splash guard plate 21 is fixedly connected to the output end of the electric telescopic rod 7, the splash guard plate 21 and the rectangular frame 24 will move vertically downward.

[0040] See also Figure 5 A clamping groove 25 is formed at the bottom of the rectangular frame 24 , and the clamping groove 25 penetrates the rectangular frame 24 and extends to the outside.

[0041] In this solution, the clamping groove 25 at the bottom end of the rectangular frame 24 abuts against the stainless steel tube 5, and the electric telescopic rod 7 is controlled to continue to extend. The rectangular frame 24 will compress the spring 23 and relatively displace with the splash guard plate 21 until the laser welding head at the bottom end of the electric telescopic rod 7 abuts against the position where the stainless steel tube 5 needs to be welded, so that the laser welding head can weld the stainless steel tube 5. At the same time, multiple springs 23 will squeeze the rectangular frame 24, so that the clamping groove 25 at the bottom end of the rectangular frame 24 clamps the stainless steel tube 5.

[0042] See also Figure 1-3 The rotating assembly 3 includes a semicircular groove 31 opened at the top of the operating table 1, and the semicircular groove 31 passes through the operating table 1 and extends to the outside.

[0043] In this solution, the semicircular groove 31 is used to provide space for placing the stainless steel pipe 5.

[0044] See also Figure 3 A plurality of invisible grooves 32 are provided inside the semicircular groove 31, and the plurality of invisible grooves 32 are all connected to the outside.

[0045] See also Figure 1-3 A plurality of rollers 33 are rotatably connected inside the invisible groove 32 , and the rollers 33 abut against the stainless steel pipe 5 .

[0046] In this solution, when it is necessary to weld other positions of the stainless steel tube 5, the pull rod 28 can be pulled in the vertical direction, the rectangular frame 24 will move vertically upward, and the spring 23 will be squeezed, so that the splash guard 21 and the rectangular frame 24 are relatively displaced until the clamping groove 25 at the bottom end of the rectangular frame 24 is away from the stainless steel tube 5, and the position limitation of the stainless steel tube 5 by the clamping groove 25 is released. Then the staff rotates the stainless steel tube 5. Since the roller 33 abuts against the stainless steel tube 5, the roller 33 will also rotate, thereby reducing the friction generated when the stainless steel tube 5 is rotated, making it easier for the staff to rotate the stainless steel tube 5. The electric telescopic rod 7 is controlled to extend again, so that the laser welding head at the bottom end of the electric telescopic rod 7 abuts against the stainless steel tube 5 to complete the secondary welding of the stainless steel tube 5.

[0047] See also Figure 3-5, the semicircular groove 31 is adapted to the clamping groove 25 .

[0048] In this solution, the semicircular groove 31 and the clamping groove 25 are used in combination, so that the elastic force of the spring 23 on the rectangular frame 24 can clamp the stainless steel tube 5.

[0049] Working principle: when the stainless steel tube 5 needs to be welded, first place the stainless steel tube 5 above the roller 33, then control the electric telescopic rod 7 to extend, and since the splash guard 21 is fixedly connected to the output end of the electric telescopic rod 7, the splash guard 21 and the rectangular frame 24 will move vertically downward until the clamping groove 25 at the bottom end of the rectangular frame 24 abuts against the stainless steel tube 5, and control the electric telescopic rod 7 to continue to extend, the rectangular frame 24 will compress the spring 23 and move relative to the splash guard 21 until the laser welding head at the bottom end of the electric telescopic rod 7 abuts against the position where the stainless steel tube 5 needs to be welded, so that the laser welding head can weld the stainless steel tube 5, and at the same time, multiple springs 23 will squeeze the rectangular frame 24, so that the clamping groove 25 at the bottom end of the rectangular frame 24 will clamp the stainless steel tube 5 clamping, when it is necessary to weld other positions of the stainless steel pipe 5, the pull rod 28 can be pulled in the vertical direction, the rectangular frame 24 will move vertically upward, the spring 23 will be squeezed, so that the splash guard 21 and the rectangular frame 24 are relatively displaced until the clamping groove 25 at the bottom end of the rectangular frame 24 is away from the stainless steel pipe 5, and the position limitation of the stainless steel pipe 5 by the clamping groove 25 is released. Then the staff rotates the stainless steel pipe 5. Since the roller 33 abuts against the stainless steel pipe 5, the roller 33 will also rotate, thereby reducing the friction generated when the stainless steel pipe 5 is rotated, making it easier for the staff to rotate the stainless steel pipe 5. The electric telescopic rod 7 is controlled to extend again, so that the laser welding head at the bottom end of the electric telescopic rod 7 abuts against the stainless steel pipe 5 to complete the secondary welding of the stainless steel pipe 5.
