There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] When welding different workpieces, in addition to the different welding forms, different devices are often used to fix workpieces of different shapes in order to facilitate rapid welding and improve welding quality. For example, when welding end workpieces such as end plugs that match the prismatic center tube to the prismatic center tube, not only must the weld be complete, but also the surfaces of the end plug and the center tube must remain flat after welding to facilitate installation and use in subsequent products. Therefore, before welding, it is necessary to align and splice the surfaces of the end plug with the prismatic center tube to ensure that the surfaces remain flat and aligned before welding, so that the welded product can be qualified.

[0004] In view of the above processing requirements, currently some simple-structured clamping tools or general clamping tools are mainly used for fixing and welding, and there is no very suitable welding device to improve the welding quality of this type of product. Based on the above reasons, the utility model proposes a prismatic center tube fitting welding device to specifically improve the fixing effect of the prismatic center tube during welding processing.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Figures 1 to 5 Shown is an embodiment of the utility model.

[0025] Embodiment 1:

[0026] like Figure 1 , 3As shown, a prismatic central tube pipe welding device comprises a bottom plate 1, two pipe placement seats 2 are arranged at intervals on the upper side of the bottom plate 1, and the two pipe placement seats 2 are arranged on the side away from each other with end component placement seats 3, and the two end component placement seats 3 are arranged vertically with vertical plates 4 on the side away from each other, and the two vertical plates 4 are adjustable and provided with push rods 5 toward the end component placement seats 3. The pipe placement seats 2 and the end component placement seats 3 can support the positions of the pipe 20 and the end component 21 close to the weld, so that the welding position can be well spliced according to the requirements. During welding, the two ends of the pipe fitting 20 are placed on the two pipe fitting seats 2 respectively, and the two end parts 21 are placed on the two end part seats 3, and the two end parts 21 are aligned and fitted with the two ends of the pipe fitting 20, and then the two end parts 21 are pushed and pressed on the two ends of the pipe fitting 20 by the push rod 5, so that the pipe fitting 20 and the end part 21 can be aligned and fixed before welding, which can not only make the end welding positions of the end parts 21 and the pipe fitting 20 aligned before welding, but also during welding, even if there is a certain degree of collision, the end parts 21 and the pipe fitting 20 will not be offset, thereby improving the quality of welding between the pipe fitting 20 and the end parts 21. A welding module is installed on one side of the bottom plate 1, and the welding module can adopt the method of automatic welding by a robot arm, or a manual welding tool, and the welding tool and the welding method can be adjusted according to the needs. A gap is left between the pipe fitting seat 2 and the end part seat 3 to facilitate the welding module to weld the connection between the pipe fitting 20 and the end part 21.

[0027] like Figure 2 , 4 As shown, the upper recess of the pipe fitting placement seat 2 is provided with a first groove 6 for fitting the outer wall of the pipe fitting 20, and the upper recess of the end piece placement seat 3 is provided with a second groove 7 for fitting the outer wall of the end piece 21. By providing the first groove 6, the pipe fitting 20 can be well fitted in the first groove 6 during welding, so that the pipe fitting 20 will not roll. For example, when the pipe fitting 20 is a hexagonal prism, the groove bottom and two groove walls of the first groove 6 fit the three adjacent faces of the pipe fitting 20 respectively. The second groove 7 is similarly matched according to the side shape of the end piece 21.

[0028] A middle support seat 8 is provided between the two pipe fitting placement seats 2. By providing the middle support seat 8, the middle part of the pipe fitting 20 can be supported, so that when welding some pipe fittings 20 with a long length, the middle part of the pipe fitting 20 can be prevented from falling, causing the pipe fitting 20 to be in a bent state and affecting the end welding.

By providing the support frame 13 and the pressure rod 14, the upper side of the end component 21 can be fixed, so that the end component 21 is stably restricted in the second groove 7 in cooperation with the second groove 7, further improving the stability and firmness of the fixation of the end component 21.

[0034] The support frame 13 includes a vertical rod 15 and a horizontal rod 16. The lower end of the vertical rod 15 is connected to the bottom plate 1. One end of the horizontal rod 16 is connected to the upper end of the vertical rod 15, and the other end is placed above the end member placement seat 3. The horizontal rod 16 is provided with a sliding hole 17 aligned with the second groove 7. The pressing rod 14 is slidably arranged in the sliding hole 17, and a pressing plate 18 is arranged at the lower end of the pressing rod 14 below the horizontal rod 16. When fixing, by driving the pressing rod 14 to move up and down in the sliding hole 17, the pressing plate 18 can be fitted to the upper side of the end member 21, so that the end member 21 is fixed in the second groove 7. When in use, the pressing rod 14 is moved upward, and after the end member 21 is placed in the second groove 7, the pressing rod 14 is moved downward to make the pressing plate 18 fit against the upper side of the end member 21.

[0035] Embodiment 4:

[0036] On the basis of Embodiment 3, a counterweight block 19 is provided at the upper end of the pressure rod 14 above the horizontal rod 16. By providing the counterweight block 19, the end member 21 can be pressed into the second groove 7 by the weight of the counterweight block 19, and the operation is convenient. The weight of the counterweight block 19 can be adjusted according to the situation.
