[0002] In modern manufacturing, especially in high-tech fields such as aerospace, automobile manufacturing, and precision machinery, rods are important structural components, and the quality of their connection directly affects the performance, safety, and reliability of the overall equipment. Thermal radiation welding, as an efficient and environmentally friendly joining technology, melts the contact surfaces of two rods to be welded through high-temperature radiation, which then rapidly cools and solidifies to form a high-strength weld. It is widely used for joining plastic materials.
[0003] Despite continuous optimization in design, existing thermal radiation welding equipment still suffers from insufficient positioning accuracy. Due to the special geometric characteristics of the rod length being much greater than its diameter, it is prone to bending and deformation, leading to a decrease in positioning accuracy.

The clamping mechanism 2 and the supporting mechanism 3 are respectively located on both sides of the heat radiation mechanism 1. The clamping mechanism 2 is used to clamp and position the first rod 100, and the supporting mechanism 3 is used to support and position the second rod 200. The bottom of the heat radiation mechanism 1 is provided with a bearing component 6 extending into the chamber 12 for positioning the first rod 100 and / or the second rod 200. The precise positioning function of the clamping mechanism 2 and the supporting mechanism 3 not only ensures the positional stability of the rods during welding, but also achieves high-precision docking through coordinated cooperation, thereby significantly improving welding quality, reducing errors, and adapting to diverse welding needs. While improving production efficiency, it also ensures the reliability and consistency of the welded joint.
[0028] The welding equipment also includes a workbench 4, the surface of which is constructed to be horizontal. The heat radiation mechanism 1, the clamping mechanism 2, and the support mechanism 3 are all fixedly connected to the top end face of the workbench 4.
[0029] like Figure 2 As shown, the clamping mechanism 2 includes a second guide rail 21 and a three-jaw chuck 22. The second guide rail 21 is fixedly connected to the worktable 4 and is arranged along a first direction. The three-jaw chuck 22 is slidably connected to the second guide rail 21.

The clamping end of the three-jaw chuck 22 is positioned towards the heat radiation mechanism 1 to clamp the end of the mandrel 300 extending from the first rod 100. The three-jaw chuck 22 drives the mandrel 300 to rotate, ensuring the mandrel 300 remains stable during rotation, thereby achieving high-precision positioning of the first rod 100 and the second rod 200 to reduce positional errors and ensure welding accuracy. The three-jaw chuck 22 moves along the second guide rail 21 towards or away from the heat radiation mechanism 1 to control the docking of the first rod 100 and the second rod 200 within the chamber 12. Preferably, the second guide rail 21 and the three-jaw chuck 22 adopt a lead screw and nut mechanism to improve the accuracy of the three-jaw chuck 22.

The limiting cover 325 is fastened to the positioning seat 323 and closes the opening of the positioning groove 324. That is, the limiting cover 325 fastens to the positioning seat 323 and closes the positioning groove 324 into a hole-like structure, which limits the second rod 200 and prevents the second rod 200 from disengaging from the positioning groove 324 during the welding process.

The horizontal movement direction of the universal joint bracket 61 is perpendicular to the first direction. The bracket 62 is fixed to the output end of the universal joint bracket, that is, the bracket 62 is fixedly connected to the top of the universal joint bracket and extends partially toward the insulation box 11. The top of the bracket 62 is recessed to form a limiting groove 63, which extends through the first direction. The bottom of the insulation box 11 is provided with an opening to allow the bracket 62 to move within the insulation box 11. Preferably, the size of the opening is slightly larger than the size of the bracket 62, so that the temperature inside the insulation box 11 can be kept constant to ensure welding quality.
[0033] In this embodiment, one bracket 62 is used to support the second rod 200 near its end. In other embodiments, two brackets 62 are used, distributed along a first direction, with the limiting grooves 63 of the two brackets 62 passing through each other along the first direction. One bracket 62 is used to support the first rod 100 near its end, and the other bracket 62 is used to support the second rod 200 near its end, so that the first rod 100 and the second rod 200 can be accurately positioned.
[0034] An adjusting assembly 7 is movably connected inside the insulated box 11. The adjusting assembly 7 contains a heating element 8 that generates heat radiation, with both ends of the heating element 8 fixed to the inner wall of the insulated box 11.

The first adjusting knob 72 is arranged along a first direction, and the first adjusting knob 72 controls the movement of the first moving member 71 by the threaded feed amount with the insulation box 11. Preferably, multiple first moving members 71 are provided to share the load-bearing force on the first moving member 71.
[0036] Specifically, a second adjusting knob 74 is provided on the side wall of the insulation box 11 facing the clamping mechanism 2. The hand-held end of the second adjusting knob 74 is located outside the insulation box 11, and the rod section of the second adjusting knob 74 is threadedly connected to the side wall of the insulation box 11.
