Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and more specifically, to a portable electric welding machine. Background Technology

[0002] In the current field of electric welding technology, the design of welding machines that facilitate the fixing of welding cables still faces many technical problems that need to be solved. Most of the welding machines on the market have significant functional defects during transportation. The main problem is that the way the welding gun and the cable are carried is not integrated enough. Operators are forced to carry the welding cable and the welding machine frame separately. This design does not take into account the convenience needs in actual working scenarios.

[0003] When operators use the clamping mechanism to secure connecting cables of varying thicknesses, the distance between the protective mechanism and the pressure plate varies significantly, while the length of the securing strap remains relatively fixed. This leads to two extreme situations: for thicker connecting cables, the securing strap needs to be excessively stretched to engage with the fixing rod, which can cause elastic fatigue, material aging, or even breakage of the securing strap over time; while for thinner connecting cables, the distance between the securing strap and the fixing rod is too short, resulting in insufficient tension and significantly reducing the securing effect, failing to effectively prevent the cable from loosening and swaying.

[0004] Another prominent defect in the design of existing welding machines is the insufficient stability of the clamping mechanism. During the movement of the equipment, the clamping parts are usually in a free state and lack an effective locking mechanism, which causes them to shake frequently during transportation. This shaking not only increases the difficulty for operators to carry the equipment and reduces the comfort of handling, but may also cause repeated impact and friction damage to the clamping parts themselves and related connecting parts.

[0031] Please see Figures 1-6 A portable welding machine includes a body 1 with a storage assembly on the body 1. The storage assembly includes a take-up roller 2, a power groove 3, a rotating handle 4, a connecting cable 5, and a flip plate 6. The take-up roller 2 is rotatably connected inside the body 1, and there are two take-up rollers 2. The power groove 3 is opened on the take-up roller 2, and the rotating handle 4 is inserted into the power groove 3. The connecting cable 5 is wound on the take-up roller 2. The flip plate 6 is rotatably connected to the top of the body 1. A fixing assembly is provided at one end of the body 1. The fixing assembly includes a top plate 7, a fixing plate 8, and guide rods 9. The top plate 7 is set on the body 1, the fixing plate 8 is set below the top plate 7, and the guide rods 9 are installed at both ends of the fixing plate 8.

[0032] A terminal block 10 is installed on the main body 1.

[0033] Connecting cable 5 passes through terminal block 10.

[0034] One end of the connecting cable 5 is connected to a terminal block 11. An elastic seat 12 is installed on the fixing plate 8. The elastic seat 12 is adapted to the connecting cable 5. A threaded rod 13 is rotatably connected to the top plate 7. A pressure plate 14 is slidably connected to the guide rod 9.

[0035] An elastic pad 15 is installed at the bottom of the pressure plate 14. The elastic pad 15 is in close contact with the connecting cable 5. A threaded cylinder 16 is installed on the pressure plate 14. The threaded cylinder 16 is threadedly connected to the threaded rod 13. Insertion holes 17 are evenly opened on the top plate 7. A pull rod 18 is slidably connected on the threaded rod 13. The pull rod 18 is adapted to the insertion hole 17. A pull block 19 is installed at one end of the pull rod 18. A spring 20 is sleeved on the guide rod 9. The two ends of the spring 20 are connected to the pressure plate 14 and the fixed plate 8.

[0036] In this embodiment, the connector 11 on the connecting cable 5 is connected to the welding gun, and the connecting cable 5 is pulled out. At this time, the take-up roller 2 is rotated. After being pulled to the appropriate position, the welding process is performed using the welding gun. After the welding process is completed, the rotating handle 4 is inserted into the power slot 3, driving the take-up roller 2 to rotate, thereby rotating the connecting cable 5 wound on it. After the connecting cable 5 is stored in the appropriate position, the pulling rod 18 is pulled, causing it to move out of the insertion hole 17 of the top plate 7, releasing the threaded rod 13. During the fixing process, the threaded rod 13 is rotated, causing the pressure plate 14 at the bottom of the threaded cylinder 16 to slide along the guide rod 9, and the elastic pad 15 is moved downwards. In conjunction with the elastic seat 12 on the fixing plate 8, the connecting cable 5 is pressed and fixed. When the pressure plate 14 slides along the guide rod 9, the spring 20 between the pressure plate 14 and the fixing plate 8 is compressed, thereby completing the fixing of the connecting cable 5. The flip plate 6 can then be rotated along the machine body 1, allowing the operator to inspect the inside of the machine body 1.

[0037] Please see Figure 1-2 As an embodiment of a portable welding machine with an installation component: an installation component is provided at one end of the machine body 1. The installation component includes a connecting shell 21, a fixing bolt 22, and a wire 23. The connecting shell 21 is detachably installed at one end of the machine body 1.

[0038] One end of the line 23 is connected to a tap 24, and a connecting post 25 is installed inside the body 1. A connecting seat 26 is slidably connected to the connecting post 25.

[0039] The connecting column 25 is threaded with a connecting bolt 27. One end of the connecting bolt 27 is tightly attached to the connecting seat 26, and the tap line 24 passes through the connecting seat 26.

[0040] More specifically, the connector 26 is slidably installed along the connector post 25, and the tap 24 on the wire 23 is passed through the connector 26 so that one end of the tap 24 is connected to the power supply inside the body 1. Then, the connector bolt 27 is installed on the connector post 25 to fix the connector 26 to the connector 25. Then, the connector shell 21 is placed against one end of the body 1 and the body 1 and the connector shell 21 are fixed together by the fixing bolt 22.

[0041] In summary, during the use or operation of the overall equipment: connect the connector 11 on the connecting cable 5 to the welding gun, and pull out the connecting cable 5. At this time, the take-up roller 2 will rotate. After pulling it to the appropriate position, the welding process is carried out using the welding gun. After the welding process is completed, insert the rotating handle 4 into the power slot 3 to drive the take-up roller 2 to rotate, thereby rotating the connecting cable 5 wound on it. After the connecting cable 5 is stored in the appropriate position, pull the pulling rod 18 to remove it from the insertion hole 17 of the top plate 7, releasing the screw. During the fixing process of the threaded rod 13, the threaded rod 13 is rotated, which drives the pressure plate 14 at the bottom of the threaded cylinder 16 to slide along the guide rod 9, and adjusts the elastic pad 15 to move downward. In conjunction with the elastic seat 12 on the fixing plate 8, the connecting cable 5 is pressed and fixed. When the pressure plate 14 slides along the guide rod 9, the spring 20 between the pressure plate 14 and the fixing plate 8 is compressed, thereby completing the fixing of the connecting cable 5. The flip plate 6 can then be rotated along the machine body 1, allowing the operator to inspect the inside of the machine body 1.

[0042] The connector 26 is slidably installed along the connector post 25, and the tap 24 on the wire 23 is passed through the connector 26 so that one end of the tap 24 is connected to the power supply inside the body 1. Then, the connector bolt 27 is installed on the connector post 25 to fix the connector 26 to the connector 25. Then, the connector shell 21 is placed against one end of the body 1 and the body 1 and the connector shell 21 are fixed together by the fixing bolt 22.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
