DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-4 As shown, the utility model proposes a stainless steel pipe interface welding device, including a welding table 1, a welding seat 2 is fixed in the middle of the top surface of the welding table 1, a welding pipe hole 3 is opened in the center of the welding seat 2 and passes through both sides of the welding seat 2, an inner rotating pipe 4 is connected to the inner side of the welding pipe hole 3, a driving mechanism 5 is fixed on one side of the top surface of the welding table 1 located in the middle of the welding seat 2, the output end of the driving mechanism 5 is drivingly connected to the inner rotating pipe 4, and a welding head 6 is fixed in the middle of the inner rotating pipe 4;

[0023] Symmetrical pipe fixing frames 8 are provided on both sides of the top surface of the welding table 1. The bottom ends of the pipe fixing frames 8 are fixed with limited sliding seats 9 that slide inside the welding table 1.

[0024] The position where the welding table 1 is connected to the limit slide 9 is provided with a lateral adjustment mechanism 10 which is drive-connected to the limit slide 9. The lateral adjustment mechanism 10 includes a threaded rod 11 and a drive motor 12. The threaded rod 11 is passed through the inner side of the welding table 1 and is screwed to the limit slide 9. The drive motor 12 is fixed to the outer wall of the side of the welding table 1, and the output end of the drive motor 12 is fixedly connected to the threaded rod 11.

[0025] The design of the pipe fixing frame 8 can improve the stability of the stainless steel pipe after it is connected to the inner rotating pipe 4, thereby improving welding safety;

[0026] The transverse adjustment mechanism 10 is driven and connected to the pipe fixing frame 8, so that the pipe can be more conveniently moved into the inner rotating pipe 4 after being connected to the inner pipe fixing frame 8, thereby ensuring the accuracy of the connection between the pipe and the welding head 6 at the welding position inside the inner rotating pipe 4;

[0027] Usage process: The pipe is passed through the pipe fixing frame 8 from both sides of the welding table 1. (It should be noted here that there is not only one single-sided pipe fixing frame 8. Different numbers of pipe fixing frames 8 can be designed according to the length of the pipe) When passing the stainless steel pipe, the electric push rod 16 inside the pipe fixing frame 8 is started to move the lower pipe jacking frame 15 to the bottom. Then the pipe is passed through the center of the upper pipe pressing frame 13 and the lower pipe jacking frame 15 and fits with the rubber gasket 17. When the position adjustment of the stainless steel pipe is completed, the electric push rod 16 is started to drive the lower pipe jacking frame 15 to move upward, pushing the stainless steel pipe to move up to abut the upper pipe pressing frame 13. Then, according to the size of the pipe, the center of the stainless steel pipe is aligned with the center of the inner rotating pipe 4.

[0028] After the pipe is fixed by the pipe fixing frame 8, the driving motor 12 inside the lateral adjustment mechanism 10 is started to drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, the limit slide 9 threadedly engaged with the threaded rod 11 will drive the pipe fixing frame 8 to move horizontally, so that the stainless steel pipe inside the pipe fixing frame 8 moves toward the inner rotating tube 4. When the stainless steel pipe moves to the center of the inner rotating tube 4, the lateral adjustment mechanisms 10 on both sides of the welding table 1 can be started according to the welding position to accurately adjust the welding position so that the welding position is vertically parallel to the welding head 6.

[0029] When the pipe welding position and the welding head 6 are adjusted correctly, the lifting and adjusting push rod 7 can be started according to the size of the stainless steel pipe (it should be noted that all the driving mechanisms 5 and the adjustment of the push rod mechanism in this device can be operated by computer automation and the driving mechanism 5, without manual operation. The programming program can be used to use the computer to automatically adjust the welding operation according to the pipe size and the required moving distance), so that the welding head 6 contacts the welding position of the stainless steel outer surface and welds the stainless steel weld joint;

[0030] During the welding process, the rotation speed of the driving mechanism 5 needs to be controlled according to the thickness of the stainless steel itself. When the thickness of the stainless steel pipe is large, the rotation of the driving mechanism 5 can be started slowly to increase the contact time between the welding head 6 and the connection position of the stainless steel pipe, thereby ensuring the firmness and strength of the welding position of the stainless steel pipe. At the same time, when the thickness of the stainless steel pipe is small, the rotation speed of the driving mechanism 5 can be increased to ensure the welding stability of the stainless steel pipe.

[0031] In this embodiment, a welding seat 2 is provided on the top surface of the welding table 1. The inner rotating tube 4 arranged inside the welding seat 2 is driven by the driving mechanism 5, so that the stainless steel pipe inserted into the inner rotating tube 4 can be driven by the driving mechanism 5 to rotate during welding, thereby completing the welding of the stainless steel pipe by the welding head 6, completing the welding of the stainless steel pipe quickly and efficiently, and at the same time, the welding stability is higher, reducing labor costs.

[0032] Example 2

[0033] like Figure 1-4 As shown, based on Example 1, a lifting adjustment push rod 7 is fixed inside the position where the inner rotating tube 4 is connected to the welding head 6, and the welding head 6 is fixed to the top of the output end of the lifting adjustment push rod 7;

[0034] An upper pipe pressing frame 13 is provided on the upper side of the pipe fixing frame 8 to limit the sliding movement. Symmetrical elastic push rods 14 are fixed on both sides of the top surface of the upper pipe pressing frame 13.

[0035] A lower pipe jacking frame 15 is provided on the lower side of the pipe fixing frame 8 and is limited and slidable. Symmetrical electric push rods 16 are fixed on both sides of the bottom surface of the lower pipe jacking frame 15 and are fixedly connected to the lower pipe jacking frame 15.

[0036] A rubber gasket 17 is fixed at the center of the opposite surfaces of the upper pipe pressing rack 13 and the lower pipe jacking rack 15 , and an arc-shaped pipe groove is opened in the middle of the rubber gasket 17 .

[0037] In this embodiment, the inner rotating tube 4 is connected to the lifting and adjusting push rod 7 set at the welding head position, which can be a stainless steel pipe welded inside the welding seat 2 and can be suitable for stainless steel pipes of various sizes;

[0038] The design of the elastic push rod 14 on the top of the upper pipe pressing rack 13 inside the pipe fixing rack 8 can give the upper pipe pressing rack 13 a downward thrust, and in conjunction with the use of the lower pipe jacking rack 15, it can enhance the stability of the stainless steel pipe clamping during the welding process. The design of the electric push rods 16 on both sides of the lower pipe jacking rack 15 can cooperate with the downward pressure of the elastic push pipe of the upper pipe pressing rack 13 to stably clamp pipes of different sizes, while keeping the centers of pipes of different sizes parallel to the center point of the inner rotating pipe 4;

[0039] The design of the rubber gasket 17 can increase the friction force of the upper pipe pressing rack 13 and the lower pipe jacking rack 15 on the stainless steel pipe.

[0040] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
