[0002] Pipe fittings are collectively referred to as the parts in the pipe fitting system that play the role of connection, control, change direction, and flow distribution. In the prior art, when the pipe fittings are welded, the ports of two adjacent pipe fittings are first aligned, then a rotating device is used to drive the two pipe fittings to rotate synchronously, and at the same time, a welding gun is used to weld the gap between the two pipe fittings, so that the two pipe fittings become one, that is, the length of the pipe fittings is increased. However, when the pipe fittings are welded, the ports of the pipe fittings are not easy to align, which leads to misalignment of the pipe fittings during welding, and the misalignment affects the quality of the welding between the pipe fittings, and further affects the improvement of the pipe welding processing qualification rate. In particular, in the port alignment welding work of special-shaped pipe fittings and straight pipe fittings, it is difficult to drive the special-shaped pipe fittings and the straight pipe fittings to rotate synchronously in the state of port alignment, which leads to the need for manual rotation of the welding gun to weld the welding area of the special-shaped pipe fittings and the straight pipe fittings.

[0021] The working steps of the intelligent alignment of the special-shaped pipe fitting 52 welding equipment are as follows.

[0022] First, the operator controls the upper electric lift 21 to drive the upper arc-shaped frame 22 to move upwards, and the upper arc-shaped frame 22 drives the upper main arc-shaped clamping plate 23, the upper arc plate 25 and the upper auxiliary arc-shaped clamping plate 27 to move upwards away from the lower arc-shaped frame 22. The operator then clamps and fixes the right end of the straight pipe 51 on the fixed clamping cone 13, and places the left end of the straight pipe 51 on the main anti-skid pad 28 of the lower main arc-shaped clamping plate 23. At the same time, the electric sliding block 14 drives the second electric rotating machine 15, the electric telescopic plate 16 and the movable clamping cone 17 to move along the left-right direction to adjust the transverse position according to the set program, and the electric telescopic plate 16 drives the movable clamping cone 17 to move along the front-back direction to adjust the transverse position according to the set program. The operator then clamps and fixes the left end of the special-shaped pipe 52 on the movable clamping cone 17, and places the right end of the special-shaped pipe 52 on the auxiliary anti-skid pad 29 of the lower auxiliary arc-shaped clamping plate 26, so as to realize the intelligent alignment and convergence of the left end of the straight pipe 51 and the right end of the special-shaped pipe 52. Then the operator controls the upper electric lift 21 to drive the upper arc-shaped frame 22 to move downwards to reset, until the two arc-shaped frames 22 converge, so that the first arc track 2201 of the two arc-shaped frames 22 together forms a complete first annular track structure, and the two main arc-shaped clamping plates 23 converge, so that the second arc track 2301 of the two main arc-shaped clamping plates 23 together forms a non-closed second annular track structure, and the lower auxiliary arc-shaped clamping plate 26 and the upper auxiliary arc-shaped clamping plate 27 converge, so that the lower third arc track 2601 structure of the lower auxiliary arc-shaped clamping plate 26 and the upper third arc track 2701 structure of the upper auxiliary arc-shaped clamping plate 27 together form a non-closed third arc track structure, and the intelligent welding gun 3 passes through the upper hollow slot 2502 of the upper arc plate 25 to align the welding area on the upper side between the straight pipe 51 and the special-shaped pipe 52.

[0023] During the process that the operator clamps and fixes the left end of the special-shaped pipe 52 on the movable clamping cone 17, the special-shaped pipe 52 pushes the fixed clamping rod 18 to twist the torsional spring 19. The torsional spring 19 generates a reverse elastic torque force after being twisted, and the fixed clamping rod 18 drives the special-shaped pipe 52 on the movable clamping cone 17 to clamp under the action of the reverse elastic torque force, thereby improving the fixing stability of the special-shaped pipe 52 on the movable clamping cone 17.

[0024] After the operator connects the intelligent welding gun 3 to the welding main machine, controls the welding main machine to control the intelligent welding gun 3 to perform welding work on the welding area between the straight pipe 51 and the special-shaped pipe 52 from top to bottom, the protective gas sprayed downward from the intelligent welding gun 3 covers the outer surface of the welding area between the straight pipe 51 and the special-shaped pipe 52 to isolate external air, the sparks and smoke generated in the welding work of the intelligent welding gun 3 pass through the lower hollow groove 2402 of the lower arc plate 24 to the outside along the outer surface of the straight pipe 51 and the special-shaped pipe 52, at the same time, the first electric rotating machine 12 drives the fixed clamping cone 13 to rotate slowly, and the second electric rotating machine 15 drives the movable clamping cone 17 connected to the electric telescopic plate 16 to rotate slowly, the fixed clamping cone 13 cooperates with the movable clamping cone 17 to drive the straight pipe 51 and the special-shaped pipe 52 to rotate synchronously, at the same time, the straight pipe 51 drives the two main arc-shaped clamping plates 23 to rotate along the first annular track structure through the main anti-skid pad 28, and the special-shaped pipe 52 drives the lower secondary arc-shaped clamping plate 26 and the upper secondary arc-shaped clamping plate 27 to rotate synchronously through the secondary anti-skid pad 29, and the stationary lower arc plate 24 and the upper arc plate 25 move around the second annular track structure on the right and the third annular track structure on the left, so as to realize that the intelligent welding gun 3 rotates one circle around the welding area between the straight pipe 51 and the special-shaped pipe 52 to complete the welding work.

[0025] After the welding work is completed, the operator controls the electric elevator 21 on the upper side to drive the arc-shaped frame 22 on the upper side to move upward, and the arc-shaped frame 22 on the upper side drives the main arc-shaped clamping plate 23 on the upper side, the upper arc plate 25 and the upper secondary arc-shaped clamping plate 27 to move upward and away from the arc-shaped frame 22 on the lower side and the straight pipe 51 and the special-shaped pipe 52, so that the upper side of the straight pipe 51 and the special-shaped pipe 52 is no longer shielded by the upper arc plate 25, and the completed welding area of the straight pipe 51 and the special-shaped pipe 52 can be cooled and cooled faster.

[0026] In addition, since the fixed clamping cone 13 and the movable clamping cone 17 are both conical structures, the conical surfaces of the fixed clamping cone 13 and the movable clamping cone 17 can adapt to different sizes of the straight pipe 51 and the special-shaped pipe 52 for clamping and fixing, and only different main anti-skid pads 28 and secondary anti-skid pads 29 need to be replaced to clamp and fix different sizes of the straight pipe 51 and the special-shaped pipe 52.

[0027] Embodiment 2, as Figures 1-9As shown, on the basis of the above-mentioned embodiment 1, a positioning ring 2503 structure is provided on the front side of the upper arc plate 25 of this embodiment, and the gun head of the intelligent welding gun 3 passes through the positioning ring 2503 to align with the front side of the welding area of ​​the straight pipe 51 and the special-shaped pipe 52, and there is a welding walking angle between the gun head of the intelligent welding gun 3 and the front side of the welding area of ​​the straight pipe 51 and the special-shaped pipe 52; a drainage tube 31 connected to the lower hollow groove 2402 is provided on the lower arc plate 24; a first suction fan 32 is installed in the drainage tube 31; two flame-blocking nets 33 are fixedly connected to the drainage tube 31, and the flame-blocking net 33 is located on the upper side of the first suction fan 32; an electronic atomizer 34 is installed on the drainage tube 31, and the inlet end of the electronic atomizer 34 is externally connected to the cooling water conveying equipment; the outlet end of the electronic atomizer 34 is connected to the drainage tube 31, and the outlet end of the electronic atomizer 34 is located on the upper side of the flame-blocking net 33.

[0028] When the intelligent welding gun 3 is welding the straight pipe 51 and the special-shaped pipe 52, the intelligent welding gun 3 is in an inclined state and is welding the straight pipe 51 and the special-shaped pipe 52 downward in front of the welding area. At the same time, the sparks and smoke generated by the welding are ejected downward along the front of the welding area of ​​the straight pipe 51 and the special-shaped pipe 52. At the same time, the first suction fan 32 promptly and continuously sucks the ejected sparks and smoke into the lower hollow groove 2402 of the lower arc plate 24 and the drainage tube 31. At the same time, the external cooling water delivery equipment continuously delivers cooling water to the electronic atomizer 34, and the electronic atomizer 34 Cooling water is sprayed into the drainage tube 31 in the form of water mist. The cooling water in the water mist state cooperates with the flame shielding net 33 to extinguish the sparks entering the drainage tube 31, preventing the high-temperature sparks from damaging the first suction fan 32. This processing step can timely guide the sparks and smoke generated by the welding of the intelligent welding gun 3 downward for suction and discharge, and prevent the sparks and smoke generated by the welding of the intelligent welding gun 3 from being sprayed along the outer surfaces of the straight pipe 51 and the special-shaped pipe 52 toward the adjacent main anti-slip pad 28 and auxiliary anti-slip pad 29, and prevent the main anti-slip pad 28 and auxiliary anti-slip pad 29 from continuous contact with high-temperature sparks, causing damage to their edge structures.

[0029] Example 3, as Figures 1-8 As shown, on the basis of the above-mentioned embodiment 1, a second through hole 1701 structure connected to the special-shaped pipe fitting 52 is provided in the movable cone 17 of this embodiment; a second suction fan 4 for pumping air outward is installed in the second through hole 1701 of the movable cone 17; a first through hole 1301 structure connected to the straight pipe fitting 51 is provided in the fixed cone 13; a plurality of air inlet holes 1302 structures are provided on the fixed cone 13, and the air inlet holes 1302 structures are connected to the first through hole 1301.

[0030] After the straight pipe 51 and the special-shaped pipe 52 are clamped by the fixed clamping cone 13 and the movable clamping cone 17, when the intelligent welding gun 3 is in the process of welding the straight pipe 51 and the special-shaped pipe 52, the second suction fan 4 continuously sucks the gas in the special-shaped pipe 52 out through the second through hole 1701 of the movable clamping cone 17, and at the same time, the fresh air outside continuously flows into the straight pipe 51 and the special-shaped pipe 52 through the gas inlet hole 1302 and the first through hole 1301 of the fixed clamping cone 13, so that the fresh air outside continuously flows through the inner wall of the welding area of the straight pipe 51 and the special-shaped pipe 52, cools and cools the welding area of the straight pipe 51 and the special-shaped pipe 52 from the inside, reduces the heat accumulation in the welding area of the straight pipe 51 and the special-shaped pipe 52, speeds up the cooling speed of the welding area of the straight pipe 51 and the special-shaped pipe 52, avoids the structure deformation of the inner wall of the welding area of the straight pipe 51 and the special-shaped pipe 52 due to serious heat accumulation, and at the same time, the second suction fan 4 continuously generates suction force in the special-shaped pipe 52, so that part of the protective gas sprayed from the intelligent welding gun 3 enters the special-shaped pipe 52 along the gap structure of the welding area of the straight pipe 51 and the special-shaped pipe 52 which has not been welded, so that the protective gas can better wrap the welding pool in the welding area of the straight pipe 51 and the special-shaped pipe 52, avoid the outside air contacting the welding pool in the welding area of the straight pipe 51 and the special-shaped pipe 52 to cause pores in the weld, and enhance the structural strength and surface appearance effect after the straight pipe 51 and the special-shaped pipe 52 are welded.
