Description

Technical Field

[0001] This utility model relates to the field of steel strip immersion technology, and in particular to a welding fixture for metal pipes and the pipes thereof. Background Technology

[0002] When welding workpieces, they are usually fixed and positioned using tooling fixtures. The positioning accuracy of the tooling fixtures often determines the welding quality. However, existing technologies often lack dedicated tooling fixtures for specific products, which means that during the welding process, the position of the workpiece needs to be constantly adjusted manually before it is fixed. This process is not only very time-consuming, resulting in low welding efficiency, but also makes it difficult to guarantee positioning accuracy, thus affecting the welding quality. Utility Model Content

[0021] The above-described welding fixture for metal pipes and the pipes thereof are described in the following steps: First, the user places the lower support pipe 9 on the first positioning part 3 for positioning. Then, the back support pipe 7 is placed on the first positioning part 3 and the second positioning part 4, so that the back support pipe 7 and the lower support pipe 9 are positioned in tandem. Simultaneously, the backrest pipe 8 is placed on the first positioning part 3, so that the backrest pipe 8 and the back support pipe 7 are positioned in tandem. Finally, the user places the mounting connecting plates 10 on both sides of the lower support pipe 9 and the rear side of the back support pipe 7, and positions them using the first positioning part 3 and the second positioning part 4. After the pipes are positioned, the first positioning clamping mechanism 5 and the second positioning clamping mechanism 6 clamp and fix the back support pipe 7, the backrest pipe 8, the lower support pipe 9, and the mounting connecting plates 10, respectively. During welding, an external welding robotic arm is used to weld the pipes. Compared with existing technologies, this method allows for clamping and welding according to the shape of the product, eliminating the need for manual adjustments to the workpiece position and subsequent fixing, thus improving welding efficiency.

[0022] like Figure 3 As shown, in some embodiments of this utility model, the first positioning part 3 includes uprights 31 symmetrically fixed to the front side of the fixture base plate 11, a positioning groove 32 symmetrically fixed to the rear side of one of the uprights 31, and a positioning plate 33 provided on the other two uprights 31. A first positioning groove 34 is symmetrically fixed below the lower support tube 9 and above the fixture base plate 11. A positioning baffle 35 is provided on both sides of each of the first positioning grooves 34 and above the fixture base plate 11. The user first places the lower support tube 9 on the first positioning groove 34 for positioning, and then the user places the back support tube 7 on the fixture base plate 11. At this time, the back support tube 7 is placed on the positioning groove 32 for positioning and cooperates with the lower support tube 9 for positioning. At the same time, the back support tube 8 is positioned above the back support tube 7 by the positioning plate 33. Finally, the user places two of the mounting connecting plates 10 on the positioning baffle 35, so that the mounting connecting plates 10 are positioned on both sides of the lower support tube 9.

[0023] like Figure 2 As shown, in some embodiments of this utility model, the second positioning part 4 includes a second positioning groove 41 symmetrically arranged above the rear side of the fixture base plate 11. Support columns 42 are symmetrically fixed on the rear side of the second positioning groove 41 and above the fixture base plate 11. A positioning horizontal plate 43 is connected and fixed above each of the support columns 42. After the support tube 7 is placed against the back, its rear side is positioned on the fixture base plate 11 through the second positioning groove 41. Then, the user positions the other mounting connecting plate 10 against the rear side of the support tube 7 through the positioning horizontal plate 43.

[0024] like Figure 3As shown, in some embodiments of this utility model, the first positioning and clamping mechanism 5 includes first fixed seats 51 symmetrically fixed to the front side of the clamp base plate 11, a first cylinder 52 fixed on each of the first fixed seats 51, a first pressure rod 53 fixed at the output end of each of the first cylinders 52, a second cylinder 54 fixed on the side backing against the support tube 7 and located above the clamp base plate 11, a second pressure rod 55 fixed at the output end of each of the second cylinders 54, and third cylinders 56 symmetrically fixed on the left and right sides of the clamp base plate 11. A third pressure rod 57 is fixed at the output end of each of the third cylinders 56. After the pipe is placed on the bracket 1, the first pressure rod 53 is moved by the first cylinder 52, so that the first pressure rod 53 pushes and squeezes the back support pipe 8 towards the front and upper side of the back support pipe 7. At the same time, the second pressure rod 55 is moved by the second cylinder 54, so that the second pressure rod 55 pushes and squeezes the back support pipe 7 towards the lower support pipe 9. Then, the third pressure rod 57 is moved by the third cylinder 56, so that the third pressure rod 57 pushes and squeezes the mounting connecting plate 10 towards the back support pipe 7.

[0025] like Figure 3 As shown, in some embodiments of this utility model, the second positioning and clamping mechanism 6 includes a second fixed seat 61 that is laterally symmetrically fixed on the rear side of the clamp base plate 11. A fourth cylinder 62 is fixed above the rear side of each second fixed seat 61. A push plate 63 is connected and fixed between the output ends of each fourth cylinder 62. The push plate 63 is moved by the fourth cylinder 62 so that it is supported and clamped on the clamp base plate 11 by the support tube 7.

[0026] A servo motor 12 is provided on the right side of the bracket 1, which can drive one of the rotating frames 2 to rotate. When the servo motor 12 drives one of the rotating frames 2 to rotate, the fixture base plate 11 rotates through the other rotating frame 2, so that the external robot can weld the pipe at different angles during welding.
