This design gives full play to the advantages of the large transmission ratio of the single-head worm gear. Combined with the high rigidity of the closed transmission, it can achieve precise torque amplification and motion transmission in a compact space. Its self-locking characteristics can also ensure the system's ability to maintain position when power is off or in a non-driven state.

[0033] A side seat 10 is fixed on the welding machine body 1, and a first rotating shaft 11 is movably arranged on the side seat 10. Two clamping rods 12 are fixed on the first rotating shaft 11 at intervals. The surface of the clamping rod 12 is wrapped with a silicone protective pad. The rod body is made of 6061-T6 aluminum alloy to achieve lightweight. The 3mm thick silicone protective pad coated on the surface is integrally formed through a molding process. It has high temperature resistance, anti-static and chemical corrosion resistance, and can effectively protect the surface finish of the workpiece during the clamping process.

[0034] A pressing gear 13 is installed on the first rotating shaft 11. An electric telescopic rod 14 is installed on one side of the welding machine body 1. The output end of the electric telescopic rod 14 is installed with a pressing rack 15. The pressing rack 15 is meshed with the pressing gear 13. The worm wheel 5, the worm 8, the pressing gear 13 and the pressing rack 15 are all treated with an environmentally friendly blue and white zinc coating, and the coating thickness is ≥15μm, meeting the ISO 2081 standard, with both anti-rust and wear-resistant functions, and is suitable for the high-humidity welding workshop environment.

[0035] Two groups of sliding grooves 16 are symmetrically opened on the welding machine body 1. Two clamping bodies 17 are slidably arranged on the sliding grooves 16. A placing table 18 is fixed on each of the two clamping bodies 17. Two limiting seats 19 are symmetrically fixed on the placing table 18. A moving clamping block 20 is arranged between the two limiting seats 19. A spring 21 is fixed between the moving clamping block 20 and the limiting seat 19. The bottom of the moving clamping block 20 is slidably connected to the placing table 18. A pushing block 22 is arranged on one side of the clamping body 17. One end of the pushing block 22 extends into the clamping body 17 and is fixed to the moving clamping block 20. A second rotating shaft 23 is movably arranged on the welding machine body 1. An adjusting gear 24 is installed on the second rotating shaft 23. Fixed rods 25 are fixed on each of the two clamping bodies 17. Adjusting racks 26 are installed on the two fixed rods 25. The two adjusting racks 26 are both meshed with the adjusting gear 24.

[0036] A material receiving pool 27 is fixed on the welding machine body 1, which is formed by stamping 304 stainless steel. Its U-shaped groove body is located directly below the two clamping bodies 17. A 0.5mm thick tungsten carbide coating is sprayed on the inner surface of the groove to resist the erosion of molten solder. An automatic tin feeder 28 is installed on the right side of the welding machine body 1 through a quick-release clamp. Its tin feeding mechanism is driven by a servo motor, equipped with a Φ1.0 - 1.6mm adaptive guiding nozzle, and the tin feeding speed is continuously adjustable from 0.1 - 2.0m / s; on the left side, a tin wire coil placing rack 29 is fixed. The rack body is made of 6061-T6 aluminum alloy anodized frame, and the oxygen content in the built-in nitrogen slow-release cavity is ≤5%, preventing the tin wire from oxidizing and deteriorating.

[0037] The safety protection device of this invention patent adopts a modular design concept. Through the coordinated action of a multi-dimensional limiting mechanism and an intelligent protection system, it improves the convenience of equipment maintenance while ensuring operation safety. Its core working principle and technical features are as follows:

[0038] Linkage safety protection system: This device innovatively adopts a double worm and worm gear drive protection mechanism, which includes two sets of precisely matched worm 5 and worm gear 8 transmission pairs. By setting two protective fences 4, it can prevent workers from reaching their hands into the working area and getting injured when the welding machine body 1 is working. When it is necessary to repair the welding head of the welding machine body 1, the operator rotates the hand crank 9 to drive the worm shaft system to drive the two worms 8 to rotate. Under the transmission action of the worm 8 and the worm gear 5, the two support shafts 3 drive the protective fences 4 to rotate in opposite directions, realizing mirror-symmetrical opening and closing. After the two protective fences 4 are unfolded, the repair work can be carried out;

[0039] Z-axis constraint: When the welding work starts, the protective fences 4 on both sides are closed, and the electric telescopic rod 14 drives the rack 15 to move. Under the transmission action of the downward pressing rack 15 and the downward pressing gear 13, the pressing rod 12 rotates downward to fix the workpiece to be welded in the longitudinal Z-axis direction, restricting the Z-axis freedom of the workpiece.

[0040] The workpiece, such as a cable, is clamped by the moving clamp block 20 and is assembled and connected through the base guide rail chute 16 between the clamping body 17 and the welding machine body 1. The semi-circular groove of the clamping body 17 is consistent with the outer diameter of the material receiving pool in the processing area, so as to realize the X-axis limit of the workpiece to be processed; The clamping body 17 is composed of a limit seat 19, a moving clamp block 20 and a spring 21 respectively. The workpiece to be processed is clamped by tightening the spring 21 of the clamping block. At the same time, a wire harness through hole with a fixed diameter is provided between the limit seat 19 and the moving clamp block 20, which is convenient for the installation, disassembly and processing of the workpiece.

[0041] The Y-axis direction of the workpiece to be processed is realized through the connection between the adjusting rack 26, the adjusting gear 24, the adjusting motor 30 and the second rotating shaft 23. The adjusting rack 26 and the placing table 18 are fixedly connected by welding

[0042] The adjusting motor 30 is fixedly installed on the welding machine body 1. Through the meshing transmission between the adjusting rack 26 and the adjusting motor 30, the adjusting motor 30 rotates forward and backward to realize the Y-axis movement of the clamping body 17. The above restrictions on the degrees of freedom of the X, Y, and Z axes prevent the position of the welded part from shifting during the welding process and affecting the welding effect. Finally, the solder wire coil placement rack 29 is placed on the front of the welding machine body 1, which is convenient for observing and replacing the solder wire. The solder wire is transported to the center of the workpiece to be processed through the solder outlet of the automatic solder feeder and melts under the high temperature of the welding tool head to realize the welding of the workpiece to be processed.

[0043] The circuits and controls involved in this invention patent are all prior arts and will not be elaborated here.

[0044] The above are only embodiments of the present invention patent, and do not thus limit the patent scope of the present invention patent. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention patent, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention patent.
