[0029] like Figure 1-Figure 6 As shown, this embodiment proposes a stainless steel composite pipe welding device, including an L-shaped base 1, and also includes a clamp adjustment component 2, which is installed on the middle inner wall of the L-shaped base 1 and is used to adjust the position of the clamp; an angle adjustment component 3, which is installed between two groups of L-shaped bases 1 and is used to adjust the angle between the two groups of L-shaped bases 1, so as to facilitate the welding of straight pipes and inclined pipes. When the inclined surface of the stainless steel pipe needs to be welded, there is no need to replace the accessories of the stainless steel inclined pipe, which not only has fast work efficiency but also high practicality.

[0030] like Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the angle adjustment component 3 includes a hydraulic cylinder 301 movably connected to the outer wall of one group of L-shaped bases 1, and the telescopic end of the hydraulic cylinder 301 is slidably connected with a telescopic rod 302, and the end of the telescopic rod 302 away from the hydraulic cylinder 301 is movably connected to the outer wall of another group of L-shaped bases 1. The telescopic rod 302 installed at its telescopic end is driven by the hydraulic cylinder 301 to extend and contract, thereby facilitating the adjustment of the angle between the two groups of L-shaped bases 1.

[0031] like Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the clamp adjustment assembly 2 includes a screw rod 201 rotatably installed at the center of the L-shaped base 1, one end of the screw rod 201 extends outward through the L-shaped base 1, and a gripping handle 202 is fixedly provided at the extended end of the screw rod 201, a slider 203 is threadedly connected to the middle section of the screw rod 201, and a symmetrically distributed limiting rod 204 is slidably connected to the inner wall of the slider 203, a lower clamp 205 is fixedly installed on the top of the slider 203, an upper clamp 206 is arranged above the lower clamp 205, and symmetrically distributed fixing screws 207 are installed between the lower clamp 205 and the upper clamp 206, which is convenient for adjusting the position of the lower clamp 205 fixedly installed on the top of the slider 203, so as to clamp stainless steel pipes of different lengths.

[0032] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, an arc-shaped support plate 4 is fixedly installed on the top of one end of any group of L-shaped bases 1 away from the holding handle 202, and a clamping plate 5 is installed on the lower clamp 205, the upper clamp 206 and the inner wall of the arc-shaped support plate 4. The inner circle of the clamping plate 5 is provided with a plurality of protrusions, which improves the stability during the welding process and avoids affecting the docking effect at the interface.

[0033] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, a connecting block 6 is fixedly installed at one end of any group of L-shaped bases 1 away from the gripping handle 202, the two groups of connecting blocks 6 are arranged to avoid each other, and a movable shaft 7 is movably installed at the junction of the two groups of connecting blocks 6, so as to facilitate the movable connection of the two groups of L-shaped bases 1.

[0034] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, a bracket 8 is provided on the top of one end of any group of L-shaped bases 1 close to the gripping handle 202, and a roller 9 is rotatably installed in the middle of the bracket 8. A driving shaft 10 is installed on the outer wall of one group of brackets 8. The driving shaft 10 is a shaft with a driving motor, and the output end of the driving shaft 10 is connected to the roller 9, which is convenient for driving the stainless steel pipe to rotate and improving the welding efficiency.

[0035] Specifically, when the utility model is used: when the straight pipe needs to be welded, the telescopic rod 302 installed at its telescopic end is firstly driven to extend by the hydraulic cylinder 301, and the angle between the two groups of L-shaped bases 1 gradually increases until the two groups of L-shaped bases 1 are on the same horizontal line;

[0036] Then, the screw rod 201 is driven to rotate by the provided holding handle 202. When the screw rod 201 rotates forward, the slider 203 threadedly connected to the screw rod 201 approaches the holding handle 202. When the screw rod 201 rotates reversely, the slider 203 moves away from the holding handle 202, thereby facilitating the adjustment of the position of the lower clamp 205 fixedly installed on the top of the slider 203, so as to facilitate the clamping of stainless steel pipes of different lengths.

[0037] Then, the stainless steel pipe to be welded is placed on the lower clamp 205 and the inner wall of the arc-shaped support plate 4, and the lower clamp 205 and the upper clamp 206 are connected by the set fixing screws 207, so as to facilitate the clamping and fixing of the stainless steel pipe to prevent loosening during the welding process and affect the welding effect. The set driving shaft 10 drives the roller 9 to rotate, so as to facilitate the rotation of the pipe during the welding process and improve the welding efficiency;

[0038] When it is necessary to weld the inclined pipe, the telescopic rod 302 installed at its telescopic end is driven to shrink by the hydraulic cylinder 301. At this time, the angle between the two groups of L-shaped bases 1 gradually decreases. When the L-shaped base 1 movably connected to one end of the telescopic rod 302 reaches the required position, it is convenient to connect the inclined surfaces of the two groups of inclined pipes. Then, the roller 9 is driven to rotate by the driving shaft 10, which is convenient for adjusting the angle of the inclined surface of the stainless steel pipe, reducing the gap between the two groups of pipes, and achieving a good welding effect.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
