[0001] This invention relates to the field of steel component welding technology, and in particular to a flipping device and method for welding steel components. Background Technology

[0002] As the core support for modern architecture, bridges, ships and heavy equipment manufacturing, the welding quality of steel structure engineering directly affects the structural safety and service life.

[0003] Welded steel pipes refer to steel pipes with seams on the surface, which are made by bending and deforming steel strips or plates into shapes such as circles and squares and then welding them together. The raw materials used for welded steel pipes are steel plates or strips.

[0004] However, current steel pipe welding equipment cannot be rotated and adjusted, which makes it impossible to adjust the angle and position when welding steel pipes, resulting in low welding efficiency and poor welding effect. Summary of the Invention

The two ends of the external gear ring each have a first sliding groove. Each of the steel pipe flipping mechanisms includes two rings, a base plate, a mounting plate, a heightening block, a second motor, and multiple spheres. The base plate has two second sliding grooves, and each of the two second sliding grooves has multiple spheres. The base plate is fixedly connected to the upper end of the base, the heightening block is fixedly connected to the upper end of the base, the second motor is fixedly connected to the upper end of the heightening block, two rings are respectively placed on the base plate and are respectively slidably adapted to the corresponding second slide grooves, the two rings are respectively fixedly sleeved on the outside of the mounting plate, the output end of the second motor is fixedly connected to the side of the mounting plate, and multiple spheres are respectively in contact with the bottom of the corresponding rings, two brackets are respectively fixedly connected to the upper end of the base, the external toothed ring is fixedly connected to the two brackets, the U-shaped plate is sleeved on the external toothed ring, the U-shaped plate is fixedly connected to the two slide plates, the two slide plates are respectively slidably adapted to the corresponding first slide grooves, two rotating shafts are respectively rotatably connected to the inside of the U-shaped plate, the other ends of the two rotating shafts are respectively fixedly connected to the gears, the gears are adapted to the external toothed rings, the first motor is fixedly connected to the side of the U-shaped plate, the output end of the first motor passes through the U-shaped plate and is fixedly connected to the corresponding rotating shaft, and the limiting clamping mechanism is disposed on the mounting plate.

[0007] Each bracket includes two fixed rods and two inclined rods. The two fixed rods are fixedly connected to the side of the external toothed ring, one end of each of the two inclined rods is fixedly connected to the corresponding fixed rod, and the other end of each of the two inclined rods is fixedly connected to the upper end of the base.

[0008] Each of the limiting clamping mechanisms includes two L-shaped plates, two first cylinders, two clamping plates, and two rubber pads. The two L-shaped plates are fixedly connected to the upper end of the mounting plate, the two first cylinders are fixedly connected to the upper end of the corresponding L-shaped plates, the output ends of the two first cylinders pass through the corresponding L-shaped plates and are fixedly connected to the corresponding clamping plates, the two rubber pads are fixedly connected to the lower end of the corresponding clamping plates, and the two rings are fixedly sleeved on the outside of the mounting plate.

[0009] The base plate has a strip groove.

[0010] The welding mechanism includes a welding torch, an extension plate, a second cylinder, and a mounting base. The extension plate is fixedly connected to the side of the U-shaped plate, the second cylinder is fixedly connected to the bottom of the extension plate, the output end of the second cylinder is fixedly connected to the mounting base, and the welding torch is fixedly connected to the bottom of the mounting base.

[0011] The two steel pipe flipping mechanisms are symmetrically arranged on the upper end of the base, and the mounting plate is located at the center point of the two rings.

[0012] The present invention also provides a method for flipping steel components for welding, which uses the above-described flipping device for welding steel components and includes the following steps: Place the steel pipe on the strip groove so that the welding positions of the two steel pipes on the left and right sides are close to each other; The first cylinder pushes the clamping plate and the rubber pad to move, and clamps and fixes the steel pipe.

Under the cooperation of the gear and the external gear ring, the U-shaped plate and the two sliding plates slide along the corresponding first sliding groove, thereby flipping and adjusting the position of the welding mechanism. The second motor drives the mounting plate to rotate, which in turn drives the two rings to rotate within their respective second grooves. The interaction of multiple spheres reduces the friction of the rings during rotation, making their rotation smoother.

[0025] This invention provides a flipping device for welding steel components, including a base 101, two limiting clamping mechanisms, a welding torch 127 flipping mechanism, two steel pipe flipping mechanisms, and a welding mechanism; the welding torch 127 flipping mechanism includes two supports 102, an external toothed ring 103, a U-shaped plate 104, two sliding plates 105, a first motor 106, two rotating shafts 107, and a gear 108, wherein the two ends of the external toothed ring 103 are respectively provided with a first sliding groove 109; Each of the steel pipe flipping mechanisms includes two rings 110, a base plate 111, a mounting plate 112, a heightening block 113, a second motor 114, and multiple spheres 115. The base plate 111 has two second sliding grooves 116, and each of the two second sliding grooves 116 has multiple circular grooves 117. Each of the brackets 102 includes two fixing rods 118 and two diagonal rods 119. Each of the limiting clamping mechanisms includes two L-shaped plates 122, two first cylinders 123, two clamping plates 124, and two rubber pads 125. The mounting plate 112 has a strip groove 126. The welding mechanism includes a welding torch 127, an extension plate 128, a second cylinder 129, and a mounting base 130.

[0026] In this specific embodiment, the steel pipe and welding mechanism can be flipped and adjusted, thereby adjusting the welding position, resulting in high welding efficiency and good welding effect.

[0027] The base plate 111 is fixedly connected to the upper end of the base 101, the rising block 113 is fixedly connected to the upper end of the base 101, the second motor 114 is fixedly connected to the upper end of the rising block 113, two rings 110 are respectively placed on the base plate 111 and are respectively slidably adapted to the corresponding second sliding groove 116, the two rings 110 are respectively fixedly sleeved on the outside of the mounting plate 112, the output end of the second motor 114 is fixedly connected to the side of the mounting plate 112, and multiple spheres 115 respectively contact the bottom of the corresponding rings 110, the two brackets 102 are respectively fixedly connected to the upper end of the base 101, and the external toothed ring 103 is fixedly connected to the two... The bracket 102 is fixedly connected, the U-shaped plate 104 is sleeved on the external gear ring 103, the U-shaped plate 104 is fixedly connected to two sliding plates 105, the two sliding plates 105 are respectively slidably adapted to the corresponding first sliding groove 109, the two rotating shafts 107 are respectively rotatably connected to the inside of the U-shaped plate 104, the other end of the two rotating shafts 107 are respectively fixedly connected to the gear 108, the gear 108 is adapted to the external gear ring 103, the first motor 106 is fixedly connected to the side of the U-shaped plate 104, the output end of the first motor 106 passes through the U-shaped plate 104 and is fixedly connected to the corresponding rotating shaft 107, and the limiting clamping mechanism is disposed on the mounting plate 112. The output end of the first motor 106 drives the corresponding rotating shaft 107 to rotate, which in turn drives the gear 108 to rotate. With the cooperation of the gear 108 and the external gear ring 103, the U-shaped plate 104 and the two sliding plates 105 slide along the corresponding first sliding groove 109, thereby flipping and adjusting the position of the welding mechanism. The second motor 114 drives the mounting plate 112 to rotate, which in turn drives the two rings 110 to rotate within the corresponding second grooves 116. The interaction of the multiple balls 115 reduces the friction of the rings 110 during rotation, making their rotation smoother. The rotation of the mounting plate 112 drives the corresponding limiting clamping mechanism to rotate, which in turn causes the steel pipe to flip, facilitating the adjustment of its position during welding. Thus, this device can flip and adjust the steel pipe and welding mechanism, thereby adjusting the welding position, resulting in high welding efficiency and good welding effect.

[0028] Secondly, the two fixing rods 118 are respectively fixedly connected to the side of the external toothed ring 103, one end of the two inclined rods 119 is respectively fixedly connected to the corresponding fixing rod 118, and the other end of the two inclined rods 119 is respectively fixedly connected to the upper end of the base 101. Through the cooperation of the two fixing rods 118 and the two inclined rods 119, the external toothed ring 103 is supported and fixed.

[0029] Meanwhile, the two L-shaped plates 122 are respectively fixedly connected to the upper end of the mounting plate 112, the two first cylinders 123 are respectively fixedly connected to the upper end of the corresponding L-shaped plates 122, the output ends of the two first cylinders 123 pass through the corresponding L-shaped plates 122 and are fixedly connected to the corresponding clamping plates 124, the two rubber pads 125 are respectively fixedly connected to the lower end of the corresponding clamping plates 124, and the two rings 110 are respectively fixedly sleeved on the outside of the mounting plate 112. The mounting plate 112 has a strip groove 126. After the steel pipe is placed in the strip groove 126, the clamping plate 124 and the rubber pad 125 are moved by the output end of the first cylinder 123, thereby limiting and fixing the steel pipe to prevent it from shaking, falling, or shifting during the flipping and welding process. In addition, the rubber pad 125 can also prevent the clamping plate 124 from making hard contact with the steel pipe, thus preventing the clamping plate 124 from scratching the steel pipe.

[0030] In addition, the extension plate 128 is fixedly connected to the side of the U-shaped plate 104, the second cylinder 129 is fixedly connected to the bottom of the extension plate 128, the output end of the second cylinder 129 is fixedly connected to the mounting base 130, and the welding torch 127 is fixedly connected to the bottom of the mounting base 130. Two steel pipe flipping mechanisms are symmetrically arranged on the upper end of the base 101, and the mounting plate 112 is located at the center point of the two rings 110. When welding is required, the output end of the second cylinder 129 pushes the mounting base 130 and the welding torch 127 to move, bringing the welding torch 127 closer to the welding position of the steel pipe. Then, the welding torch 127 is started to perform the welding work, and the two steel pipes on the left and right will flip simultaneously. The second motors 114 on both sides will start simultaneously, and the principle and controller of the coordinated operation of the two second motors 114 are detailed in the existing public technology (CN222839580U), and will not be elaborated further here.

[0031] When using the steel component welding flipping device of this embodiment, the output end of the first motor 106 drives the corresponding rotating shaft 107 to rotate, which in turn drives the gear 108 to rotate. Under the cooperation of the gear 108 and the external gear ring 103, the U-shaped plate 104 and the two sliding plates 105 slide along the corresponding first sliding groove 109, thereby flipping and adjusting the position of the welding mechanism. The output end of the second motor 114 drives the mounting plate 112 to rotate, which in turn drives the two rings 110 to rotate in the corresponding second sliding groove 116. Through the cooperation of the multiple balls 115, the friction of the rings 110 during rotation is reduced, making their rotation smoother. The rotation of the mounting plate 112 drives the corresponding limiting clamping mechanism to rotate, which in turn drives the steel pipe to flip, facilitating the adjustment of the position during welding. Thus, this device can flip and adjust the steel pipe and the welding mechanism, thereby adjusting the welding position, resulting in high welding efficiency and good welding effect. Through the cooperation of the two fixed rods 118 and the two inclined rods 119, The external toothed ring 103 is supported and fixed respectively; after the steel pipe is placed in the strip groove 126, the clamping plate 124 and the rubber pad 125 are moved by the output end of the first cylinder 123, thereby limiting and fixing the steel pipe to prevent it from shaking, falling, or shifting during the flipping and welding process. Furthermore, the rubber pad 125 also prevents hard contact between the clamping plate 124 and the steel pipe, avoiding scratches caused by the clamping plate 124. When welding is required, the second cylinder... The output end of cylinder 129 pushes the mounting base 130 and the welding torch 127 to move, bringing the welding torch 127 closer to the welding position of the steel pipe. Then, the welding torch 127 is started to perform welding work. In addition, due to the obstruction of the fixing rod 118 and the inclined rod 119, the U-shaped plate 104 cannot rotate 360° on the outer toothed ring 103. However, through the setting of the steel pipe flipping mechanism, the steel pipe can also be flipped. Therefore, the welding torch 127 can still weld the steel pipe at all angles without any welding dead angles.

[0032] Please see Figure 7 , Figure 7 This is a flowchart illustrating the steps of the steel component welding flipping method of the present invention. The present invention also provides a steel component welding flipping method, comprising the following steps: S1: Place the steel pipe on the strip groove so that the welding positions of the two steel pipes on the left and right sides are close to each other; S2: The clamping plate 124 and the rubber pad 125 are moved by the first cylinder 123 to clamp and fix the steel pipe; S3: The first motor 106 drives the gear 108 to rotate, thereby driving the U-shaped plate 104 and the two slide plates 105 to slide along the corresponding first slide groove 109, thereby flipping and adjusting the angle of the welding torch 127; S4: The second motor 114 drives the mounting plate 112 to rotate, thereby flipping and adjusting the angle of the steel pipe; S5: The second cylinder 129 pushes the welding torch 127 to move, and at the same time starts the welding torch 127 to weld the two steel pipes.
