[0021] During operation, an electric-controlled movable platform 5 is set at one end of the top of the base 1, the position of the electric-controlled movable platform 5 is adjusted, and the support column 6 set at the top of the electric-controlled movable platform 5 is rotated, and the second steel pipe 3 is fixed from the inner wall of the second steel pipe 3 by using the rubber anti-sliding block 38, and then the support column 6 is rotated to make the electric-controlled movable platform 5 drive the second steel pipe 3 to reset, and the rubber anti-sliding block 38 is loosened, so that the second steel pipe 3 is placed on the electric rollers 29 installed at both ends of the top of the stable platform 28, and an electric-controlled placing platform 4 is set at one end of the top of the base 1 away from the electric-controlled movable platform 5, and the first steel pipe 2 is placed on the surface of the electric-controlled placing platform 4, and the angle of the auxiliary bracket 19 is adjusted by using the hydraulic telescopic rod 21 so that the auxiliary roller set at one end of the auxiliary bracket 19 The cylinder 20 fits the surface of the second steel pipe 3 and aligns the second steel pipe 3 with the first steel pipe 2. At this time, the electric telescopic rod 22 set at the center of the inner wall of the support column 6 is started, so that the output end of the electric telescopic rod 22 drives the center platform 23 to move to the joint between the first steel pipe 2 and the second steel pipe 3, and the first adjustment telescopic rod 24 and the third adjustment telescopic rod 32 are started, so that the elastic roller bracket 27 and the grinding wheel 33 set at their output ends respectively fit the inner walls of the first steel pipe 2 and the second steel pipe 3.

At the same time, the welding gun 26 is started to perform staggered welding on the gap between the inner walls of the first steel pipe 2 and the second steel pipe 3, and the first steel pipe 2 is aligned with the inner wall of the second steel pipe 3. The inner wall between the first steel pipe 2 and the second steel pipe 3 is preliminarily connected, and an electric lifting platform 7 is set on the top of the support column 6, and the electric lifting platform 7 and the adjustment bracket 8 set on the output end of the adjustment bracket 8 are adjusted to make the filler 9 set at the output end of the adjustment bracket 8 move to the gap between the first steel pipe 2 and the second steel pipe 3, and the fitting brackets 13 set on both sides of the outer wall of the filler 9 fit with the surfaces of the first steel pipe 2 and the second steel pipe 3, and the electric vibration rod 12 set at the center of the bottom of the filler 9 is inserted into the gap between the first steel pipe 2 and the second steel pipe 3. At this time, the flux particles are poured into the gap between the first steel pipe 2 and the second steel pipe 3 through the feed pipe 10 set at the top of the filler 9, and discharged into the gap between the first steel pipe 2 and the second steel pipe 3 through the discharge pipe 11 set at the bottom of the filler 9.

At this time, the arc welding head 43 set at the bottom of the filler 9 away from the end of the discharge pipe 11 is used to weld and heat the flux particles in the gap between the first steel pipe 2 and the second steel pipe 3, and make the flux particles fully contact with the steel, so as to complete the welding after the flux particles are cooled. This further solves the problem that in the traditional large-scale steel processing and welding process, when welding steel pipes with a thick surface thickness, the welding surface of the steel pipe often needs to be processed in advance, which makes the steel pipe welding process more cumbersome.

[0022] The adjusting mechanism includes a motor 14 fixedly connected to the center of the inner cavity of the base 1, and the output end of the motor 14 is fixedly connected to a transmission gear 15, and the two sides of the outer wall of the transmission gear 15 are respectively meshed with linkage gears 16, and the center of the outer wall of the linkage gear 16 is fixedly connected to a bidirectional screw rod 17, and the two ends of the bidirectional screw rod 17 are rotatably connected to the inner wall of the base 1, and the two ends of the outer wall of the bidirectional screw rod 17 are respectively threadedly connected to a moving platform 18, and one end of the top of the moving platform 18 is rotatably connected to an auxiliary bracket 19, and one end of the auxiliary bracket 19 is rotatably connected to an auxiliary roller 20, a hydraulic telescopic rod 21 is installed at the end of the top of the moving platform 18 away from the auxiliary bracket 19, and the output end of the hydraulic telescopic rod 21 is rotatably connected to the center of the bottom of the auxiliary bracket 19, a stabilizing platform 28 is fixedly connected to the top center of the base 1, and the top of the stabilizing platform 28 overlaps the bottom of the second steel pipe 3, and electric rollers 29 are installed at both ends of the top of the stabilizing platform 28, and the outer wall of the electric roller 29 overlaps the outer wall of the second steel pipe 3.

[0023] During operation, a stabilizing platform 28 is set at the center of the top of the base 1, the second steel pipe 3 is placed on the surface of the stabilizing platform 28, and the electric rollers 29 set at both ends of the top of the stabilizing platform 28 are started to drive the second steel pipe 3 to rotate slowly. When the diameter of the second steel pipe 3 is larger than the arc-shaped placement surface of the stabilizing platform 28, the motor 14 set at the center of the inner cavity of the base 1 is started to drive the transmission gear 15 set at the output end, and the transmission gear 15 drives the linkage gears 16 set on both sides of the outer wall, so that the linkage gear 16 drives the bidirectional screw rod 17 set at the center of the outer wall to rotate, and a moving platform 18 is set at both ends of the outer wall of the bidirectional screw rod 17, so that the bidirectional screw rod 17 is used to drive the moving platform 18 to move, and a hydraulic telescopic rod 21 is set at one end of the top of the moving platform 18, and the opening and closing angle of the auxiliary bracket 19 is adjusted by the hydraulic telescopic rod 21, and the auxiliary roller 20 set at one end of the auxiliary bracket 19 is fit with the outer wall of the second steel pipe 3, so as to limit the second steel pipe 3 and avoid deviation between the welding surfaces of the steel pipes, thereby affecting the subsequent use of the steel pipes.

[0024] The stabilizing mechanism includes an electric telescopic rod 22 fixedly connected to the center of the inner wall of the support column 6, and the output end of the electric telescopic rod 22 is fixedly connected to a center platform 23, the top of the center platform 23 is fixedly connected to a first adjusting telescopic rod 24, and the output end of the first adjusting telescopic rod 24 is fixedly connected to an electric-controlled swing platform 25, the inner wall of the electric-controlled swing platform 25 is installed with a welding gun 26, and the two ends of the outer wall of the electric-controlled swing platform 25 are rotatably connected to elastic roller brackets 27, and the outer walls of the elastic roller brackets 27 are respectively overlapped with the inner walls of the first steel pipe 2 and the second steel pipe 3, the bottom of the center platform 23 is fixedly connected to a second adjusting telescopic rod 30, and the output end of the second adjusting telescopic rod 30 is fixedly connected to a high-frequency knocking block 31, several third adjusting telescopic rods 32 are respectively installed on both sides of the outer wall of the center platform 23, and the output end of the third adjusting telescopic rod 32 is fixedly connected to a grinding wheel 33, and the outer walls of the grinding wheel 33 are respectively overlapped with the inner walls of the first steel pipe 2 and the second steel pipe 3.

[0025] During operation, an electric telescopic rod 22 is arranged at the center of the inner wall of the support column 6, and the electric telescopic rod 22 is used to drive the center platform 23 arranged at its output end to move to the gap between the first steel pipe 2 and the second steel pipe 3. At this time, the third adjustment telescopic rods 32 respectively arranged on both sides of the outer wall of the center platform 23 are started to make the grinding wheels 33 arranged at its output end fit with the inner walls of the first steel pipe 2 and the second steel pipe 3. When the electric control placement table 4 and the electric roller 29 drive the first steel pipe 2 and the second steel pipe 3 to rotate, the grinding wheel 33 is used to grind the gap between the first steel pipe 2 and the second steel pipe 3. When the gap between the first steel pipe 2 and the second steel pipe 3 is polished, the first adjusting telescopic rod 24 provided on the top of the center platform 23 is started, so that the electric-controlled swing platform 25 provided at its output end is close to the top of the inner wall of the first steel pipe 2 and the second steel pipe 3, and the elastic roller brackets 27 provided at both ends of the outer wall of the electric-controlled swing platform 25 are fitted with the inner walls of the first steel pipe 2 and the second steel pipe 3. At this time, the electric-controlled swing platform 25 is started, so that the welding gun 26 installed on its inner wall continuously swings slightly at the gap between the first steel pipe 2 and the second steel pipe 3, and the gap between the first steel pipe 2 and the second steel pipe 3 is staggered. The first steel pipe 2 and the second steel pipe 3 are connected to form a thinner welding surface on the inner wall of the first steel pipe 2 and the second steel pipe 3, which is convenient for supporting the subsequent pouring of the flux particles. When the outer wall of the first steel pipe 2 and the second steel pipe 3 is welded, the second adjustment telescopic rod 30 provided at the bottom of the center platform 23 is started, and the high-frequency knocking block 31 provided at the output end is fitted to the bottom of the inner wall of the first steel pipe 2 and the second steel pipe 3. The high-frequency knocking block 31 is started to break the thinner bottom surface produced by the staggered welding of the inner wall of the first steel pipe 2 and the second steel pipe 3, so that the solid welding surface produced by the welding of the flux particles is exposed. When the first steel pipe 2 and the second steel pipe 3 are welded, the second adjustment telescopic rod 30 provided at the bottom of the center platform 23 is started, and the high-frequency knocking block 31 provided at the output end is fitted to the bottom of the inner wall of the first steel pipe 2 and the second steel pipe 3. After the intersecting surface with the inner wall of the second steel pipe 3 is completely smashed, the electric telescopic rod 22 is started to drive the center platform 23 to move slightly, and the grinding wheel 33 is moved to the joint gap between the first steel pipe 2 and the second steel pipe 3, and then the grinding wheel 33 is started again to grind the welding impurities remaining on the welding intersecting surface smooth, which further solves the problem that in the traditional large-scale steel processing and welding process, when facing the welding of large steel pipes, manual entry into the steel pipe is often required to work, which not only makes the working environment crowded and narrow, affecting work efficiency, but also easily inhales harmful gases generated by welding into the body, thereby affecting the health of the workers.

[0026] One side of the outer wall of the support column 6 is fixedly connected to an electric telescopic frame 34, and the output end of the electric telescopic frame 34 is fixedly connected to a number of moving blocks 35, and one end of the inner cavity of the moving block 35 is rotatably connected to a right-angle linkage rod 36, one end of the right-angle linkage rod 36 is rotatably connected to a fixed bracket 37, and the top of the fixed bracket 37 is fixedly connected to a rubber anti-slider 38, and the end of the inner wall of the fixed bracket 37 close to the right-angle linkage rod 36 is rotatably connected to a limiting rod 39, and one end of the limiting rod 39 is rotatably connected to an extension block 40, and the end of the outer wall of the extension block 40 away from the limiting rod 39 is fixedly connected to a side of the outer wall of the support column 6 close to the electric telescopic frame 34.

[0027] During operation, an electric telescopic frame 34 is set on one side of the outer wall of the support column 6, and several moving blocks 35 are set at the output end of the electric telescopic frame 34. When the second steel pipe 3 needs to be fixed, the electric telescopic frame 34 is started, so that its output end pushes the moving block 35, and the right-angle linkage rod 36 set at one end of the inner cavity of the moving block 35 is fulcrumed with the right-angle end and the extension block 40, so that the other end of the right-angle linkage rod 36 is fulcrumed with the fixed bracket 37 to push the rubber anti-sliding block 38 set on its top, and fit the inner wall of the second steel pipe 3. During this period, a limiting rod 39 is set on the inner wall of the fixed bracket 37 close to one end of the right-angle linkage rod 36, and the other end of the limiting rod 39 is connected to the extension block 40, so that the limiting rod 39 is used to limit the rubber anti-sliding block 38 to prevent the rubber anti-sliding block 38 from tilting up during the fitting process of the rubber anti-sliding block 38 on the inner wall of the second steel pipe 3, thereby causing unstable clamping.

[0028] A roller bracket 41 is fixedly connected to one side of the bottom of the filler 9 close to the discharge pipe 11, and the bottom of the roller bracket 41 is overlapped with the top of the first steel pipe 2 and the second steel pipe 3 respectively, and an elastic discharge plate 42 is rotatably connected between one side of the inner wall of the roller bracket 41, and an arc welding head 43 is installed on the end of the bottom of the filler 9 away from the discharge pipe 11.

[0029] During operation, a roller bracket 41 is provided at one side of the bottom of the filler 9 close to the discharge pipe 11, so that the bottom of the roller bracket 41 is fitted with the top of the first steel pipe 2 and the second steel pipe 3, and an elastic discharge plate 42 is provided between one side of the inner wall of the roller bracket 41, so that the flux particles discharged from the discharge pipe 11 slide along the elastic discharge plate 42 into the gap between the first steel pipe 2 and the second steel pipe 3, and the flux particles entering the gap between the first steel pipe 2 and the second steel pipe 3 are brought into contact with the electric vibration rod 12, and the electric vibration rod 12 is used to shake the flux particles apart, thereby reducing the gaps between the flux particles. At this time, the arc welding head 43 provided at one end of the bottom of the filler 9 away from the discharge pipe 11 is started to heat and weld the flux particles in the gap, so that the flux particles are fully in contact with the welding surface between the first steel pipe 2 and the second steel pipe 3, thereby reducing the occurrence of cavities between the flux particles during welding, thereby affecting the welding strength of the steel pipes.

[0030] An intelligent welding method for processing large steel materials, which uses the above-mentioned intelligent welding device for processing large steel materials, is as follows: S1: The first steel pipe 2 and the second steel pipe 3 are placed on the surfaces of the electric control placement table 4 and the stabilization table 28 respectively, and the welding surface between the first steel pipe 2 and the second steel pipe 3 is aligned by using the adjustment mechanism. Then, the stabilization mechanism is used to perform initial welding on the gap between the inner walls of the first steel pipe 2 and the second steel pipe 3. After the initial welding is completed, the filler 9 is started, and the arc welding head 43 is used to weld the gap between the outer walls of the first steel pipe 2 and the second steel pipe 3; S2: The adjustment mechanism drives the bidirectional screw rod 17 through the motor 14 to adjust the movable platform 18 provided at both ends of the outer wall, and uses the hydraulic telescopic rod 21 to adjust the angle of the auxiliary bracket 19, so that the auxiliary roller 20 provided at one end of the auxiliary bracket 19 is adjusted to fit the second steel pipe 3; S3: The stabilizing mechanism pushes the welding gun 26 to perform initial welding on the gap between the inner walls of the first steel pipe 2 and the second steel pipe 3 through the first adjusting telescopic rod 24 set on the top of the central platform 23. When the welding of the gap between the outer walls of the first steel pipe 2 and the second steel pipe 3 is completed, the high-frequency knocking block 31 is started to break the initial welding sheet, and the broken position is ground with the grinding wheel 33.

[0031] The following is a detailed description of the working principles of the intelligent welding device and welding method for large steel processing.

[0032] like Figure 1-10As shown, by setting an electric-controlled movable platform 5 at one end of the top of the base 1, adjusting the position of the electric-controlled movable platform 5, and rotating the support column 6 set on the top of the electric-controlled movable platform 5, the second steel pipe 3 is fixed from the inner wall of the second steel pipe 3 using the rubber anti-sliding block 38, and then rotating the support column 6 to allow the electric-controlled movable platform 5 to drive the second steel pipe 3 to reset, and release the rubber anti-sliding block 38, by setting a stabilizing platform 28 at the center of the top of the base 1, the second steel pipe 3 is placed on the surface of the stabilizing platform 28, and starting the electric rollers 29 respectively set at the two ends of the top of the stabilizing platform 28 to drive the second steel pipe 3 to rotate slowly. When the diameter of the second steel pipe 3 is larger than the arc-shaped placement surface of the stabilizing platform 28, the motor 14 set at the center of the inner cavity of the base 1 is started to drive the motor 14 set at the output end. The transmission gear 15 is used to drive the linkage gears 16 respectively provided on both sides of the outer wall, so that the linkage gears 16 drive the bidirectional screw 17 provided at the center of the outer wall to rotate, and a moving platform 18 is respectively provided at both ends of the outer wall of the bidirectional screw 17, so that the bidirectional screw 17 is used to drive the moving platform 18 to move, and a hydraulic telescopic rod 21 is provided at one end of the top of the moving platform 18, and the opening and closing angles of the auxiliary bracket 19 are adjusted by the hydraulic telescopic rod 21, and the auxiliary roller 20 provided at one end of the auxiliary bracket 19 is fitted with the outer wall of the second steel pipe 3, so as to limit the second steel pipe 3 and avoid deviation between the welding surfaces of the steel pipes, thereby affecting the use of subsequent steel pipes. The electric-controlled placing table 4 is used to place the first steel pipe 2 on the surface of the electric-controlled placing table 4, and the angle of the auxiliary bracket 19 is adjusted by the hydraulic telescopic rod 21, so that the auxiliary roller 20 set at one end of the auxiliary bracket 19 fits the surface of the second steel pipe 3, and the second steel pipe 3 is aligned with the first steel pipe 2. At this time, the electric telescopic rod 22 set at the center of the inner wall of the support column 6 is started, so that the output end of the electric telescopic rod 22 drives the center platform 23 to move to the joint between the first steel pipe 2 and the second steel pipe 3, and the first adjustment telescopic rod 24 and the third adjustment telescopic rod 32 are started, so that the elastic roller bracket 27 and the grinding wheel 33 set at their output ends respectively fit the inner walls of the first steel pipe 2 and the second steel pipe 3. At this time, the electric-controlled placing table 4 and the electric roller 29 are started, so that the first steel pipe 2 and the second steel pipe 3 are aligned. The pipes 3 rotate synchronously, and at the same time, the welding gun 26 is started to perform staggered welding on the gap between the inner walls of the first steel pipe 2 and the second steel pipe 3, and the inner walls of the first steel pipe 2 and the second steel pipe 3 are preliminarily connected. By setting an electric lifting platform 7 on the top of the support column 6, adjusting the electric lifting platform 7 and the adjustment bracket 8 set at the output end of the adjustment bracket 8, the filler 9 set at the output end of the adjustment bracket 8 is moved to the gap between the first steel pipe 2 and the second steel pipe 3, and the fitting brackets 13 set on both sides of the outer wall of the filler 9 are fitted with the surfaces of the first steel pipe 2 and the second steel pipe 3, and the electric vibration rod 12 set at the bottom center of the filler 9 is inserted into the gap between the first steel pipe 2 and the second steel pipe 3. At this time, the flux particles are poured in through the feeding pipe 10 set at the top of the filler 9.The flux is then discharged into the gap between the first and second steel pipes 2 and 3 through the discharge pipe 11 at the bottom of the filler 9. Due to the preliminary welding of the first and second steel pipes 2 and 3, the injected flux particles accumulate at the welding point. The electric vibrating rod 12 is used to knock and disperse the flux particles in the gap, reducing the gaps between the flux particles. At this time, the arc welding head 43 at the end of the bottom of the filler 9 away from the discharge pipe 11 is used to heat the flux particles in the gap of the steel pipes and ensure full contact between the flux particles and the steel. The welding is then completed after the flux particles have cooled.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
