[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 2 The present invention provides an embodiment of a simple welding tool, comprising a base 1, which serves as the basic support component of the entire tool. A circular plate 2 is fixedly connected to the top side of the base 1. The circular plate 2 plays a positioning and auxiliary support role in the tool. The top rear end of the base 1 is also fixedly connected to a top seat 4, which provides a support position for subsequent component installation.

[0032] Guide pillars 3 are fixedly connected to the left and right ends of the top seat 4. These guide pillars 3 ensure the accuracy and stability of the tooling operation. The middle part of the top seat 4 is slidably connected to the first straight row 5, and the bottom side of the first straight row 5 is welded with the first copper bar group 6 by a laser welder. The first straight row 5 can slide relatively in the middle of the top seat 4 to adjust the position to better perform the welding operation on the first copper bar group 6. Similarly, the left end of the top seat 4 is slidably connected to the second straight row 7, and the bottom side of the second straight row 7 is welded with the second copper bar group 8 by a laser welder, and the right end of the top seat 4 is slidably connected to the third straight row 9, and the bottom side of the third straight row 9 is welded with the third copper bar group 10 by a laser welder. These straight rows and copper bar groups in different positions can be slid and adjusted according to actual needs to adapt to different welding conditions, and the use of laser welding technology shortens the welding time, thereby improving the overall production efficiency and meeting the needs of high-volume production. At the same time, the heat impact generated by laser welding is small, which reduces the risk of thermal deformation of surrounding materials, maintains the physical properties of the copper bar, and extends its service life.

[0033] A positioning block 11 is slidably connected to the rear end of the base 1. Two positioning posts 12 are fixedly connected to the rear right end of the base 1. A positioning plate 13 is fixedly connected to the rear side of the positioning block 11. The outer ends of the two positioning posts 12 are slidably connected to the left and right inner walls of the positioning plate 13, respectively. The front sides of two nuts 14 contact the left and right ends of the rear side of the positioning plate 13. This design allows the positioning block 11 to be slidably adjusted on the positioning posts 12 via the positioning plate 13 and fixed in place by the nuts 14, thus achieving installation.

[0034] Reference Figure 1 、 Figure 3 and Figure 4, both left and right ends of the top seat 4 are slidably connected with a sliding post 15, and the outside of the sliding post 15 is fixedly connected with a reset component for resetting the sliding post 15. Among them, the reset component includes a ring 16, the inside of the ring 16 is fixedly connected to the outside of the sliding post 15, and the rear side of the ring 16 is fixedly connected to a spring 17. The rear ends of the two springs 17 are respectively fixedly connected to the left and right ends of the top of the top seat 4, and at the same time, the outsides of the two rings 16 are respectively slidably connected to the left and right ends of the top of the top seat 4. This structural design allows the sliding post 15 to achieve a reset function through the elastic force of the spring 17 after a sliding operation, and the ring 16 plays the role of connection and auxiliary sliding;

[0035] An opening plate 18 is fixedly connected to the rear side of the reset assembly, and the rear side of the sliding column 15 is fixedly connected to the front side of the opening plate 18. The exteriors of the two opening plates 18 are slidably connected to the left and right ends of the top of the top seat 4 for transmitting thrust. T-shaped plates 19 are slidably connected to the left and right ends of the opening plates 18. The adjacent sides of the two T-shaped plates 19 contact the left and right sides of the first straight row 5, respectively, for fixing two of the T-shaped plates 19. The distant sides of the other two T-shaped plates 19 contact the adjacent sides of the second straight row 7 and the third straight row 9, respectively, for fixing the other two T-shaped plates 19. The left and right ends of the opening plate 18 are slidably connected to the interiors of the two T-shaped plates 19. Convex cavities are defined on the left and right ends of the top of the top seat 4, and strip-shaped openings 20 are defined within the T-shaped plates 19. The T-shaped plate 19 can be slidably adjusted on the opening plate 18, and through contact with the straight row, it further positions or fixes the straight row. The convex cavity and the strip opening 20 provide space and guidance for the movement or connection of other components.

[0036] Working principle: First, divide the first straight bar 5 and the first copper bar group 6, the second straight bar 7 and the second copper bar group 8, and the third straight bar 9 and the third copper bar group 10 into three groups;

[0037] When welding the second straight row 7 and the second copper row group 8, the second copper row group 8 is put on the outside of the circular plate 2, and then the second straight row 7 is passed through the opening at the left end of the top seat 4, and then the left slide post 15 is pressed, so that the slide post 15 can push the ring 16 to slide, and then drive the spring 17 to slide, thereby giving the slide post 15 a force in the opposite direction to reset, and then the slide post 15 will push the opening plate 18 to slide, and then push the corresponding two T-shaped plates 19 to slide to the adjacent side. At this time, the second straight row 7 is placed on the leftmost side of the top seat 4, and the bottom is fitted with the second copper row group 8, and then the tension on the left slide post 15 is released, so that the force of the spring 17 returning to the slide post 15 is transmitted to the slide post 15, and then transmitted to the corresponding two T-shaped plates 19 through various components to reset and fix the second straight row 7, so that there is no need to fix it manually, thereby avoiding the phenomenon of fatigue caused by the hand fixing it all the time, thereby improving the comfort of work, and then welding them together through laser welding technology to complete the tooling;

[0038] When welding the first straight bar 5 and the first copper bar group 6 and the third straight bar 9 and the third copper bar group 10, the first straight bar 5 is placed in the middle opening of the top seat 4, and the third straight bar 9 is placed in the opening at the right end of the top seat 4. The rest of the steps are the same as the installation of the second straight bar 7 and the second copper bar group 8. However, when welding the first straight bar 5 and the first copper bar group 6, move the notch at the top of the positioning block 11 to the left, drive the positioning plate 13 through the two positioning columns 12, and then snap it into the inside of the base 1, and finally put the two nuts 1 4 are respectively screwed into the inside of the two positioning posts 12 to complete the installation of the positioning block 11, so that the second copper bar group 8 can be engaged with the positioning block 11 and the base 1, thereby facilitating welding. When facing the installation of the third copper bar group 10, it is only necessary to follow the steps of installing the second copper bar group 8 and turn the positioning block 11 180 times, thereby repeating the installation steps of the first straight bar 5 and the first copper bar group 6. Therefore, it is possible to use different cables and bar groups for installation, thereby eliminating the need to use different types of devices, thereby saving production costs.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
