[0033] The technical solution of the present invention is clearly and completely explained below in conjunction with the accompanying drawings. The described embodiments are only a part of the present invention. Based on the key points of the present invention, all other inventions and creations obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0034] like Figure 1 — Fig.17 As shown, a high-precision shunt welding tool of the present embodiment comprises a welding tool base plate 1 for fixing a shunt assembly 8, a connecting plate assembly 2, a positioning plate assembly 3, a guide rod 4, a fixed guide rail slider assembly 5, a support block 6, a quick clamp 7, and an insulating base plate 9. In the present embodiment, the shunt assembly 8 is fixedly welded on the insulating base plate 9 above the welding tool base plate 1.

[0035] A connecting plate assembly 2 is installed at one end of the welding tool base plate 1 of the present embodiment, and a support block 6 and a quick clamp 7 are installed at the other end. In the present embodiment, the positioning plate assembly 3 and the fixed guide rail slider assembly 5 are installed between the connecting plate assembly 2 and the support block 6, and the fixed guide rail slider assembly 5, the guide rod 4, the positioning plate assembly 3, the support block 6, the quick clamp 7 and the diverter assembly 8 are all installed on the insulating base plate 9 above the welding tool base plate 1. An insulating plate 10 is provided between the connecting plate assembly 2 and the positioning plate assembly 3, and the insulating plate 10 is fixedly connected to the connecting plate assembly 2 to ensure reliable insulation between the connecting plate assembly 2 and the positioning plate assembly 3. In the present embodiment, the welding tool base plate 1 and the connecting plate 21 are both rectangular brass blocks.

[0036] Depend on Figure 1 — Figure 5It can be seen that the connecting plate assembly 2 of this embodiment includes a connecting plate 21, a water joint 22 and a copper electrode 23. The water joint 22 is installed on the connecting plate 21 by bolts, and the copper electrode 23 is fixedly installed on the connecting plate 21 by tightening nuts; guide rod positioning holes 24 are respectively provided at both ends of the connecting plate 21, and guide rods 4 are respectively installed in the guide rod positioning holes 24 at both ends of the connecting plate 21. One end of the guide rod 4 of this embodiment is installed on the connecting plate 21 by a nut, and the other end is installed on the support block 6 by a nut. In this embodiment, there are two water joints 22, which are respectively installed perpendicularly on the front and upper end surfaces of the connecting plate 21 to ensure that the weldment is cooled when the welding temperature is too high.

[0037] Depend on Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 It can be seen that the positioning plate assembly 3 of this embodiment is movably mounted on the guide rod 4 between the connecting plate assembly 2 and the support block 6, and the two ends of the guide rod 4 are symmetrically fixed by the connecting plate assembly 2 and the support block 6 through nuts. The positioning plate assembly 3 can slide along the guide rod 4 in the B direction to position the diverter assembly 8 in the B direction (radial). The positioning plate assembly 3 of this embodiment includes a positioning plate 31 and a ball screw 32. In this embodiment, the positioning plate 31 is a "Л" type, and one side wall inside the positioning plate 31 is inclined. The other side of the positioning plate 31 is provided with a weldment loading and unloading station 33 of the welding position of the diverter assembly 8. The ball screw 32 is installed on the positioning plate 31 at one end of the weldment loading and unloading station 33, which is used to adjust the relative position of the diverter and the strong current terminal in the diverter assembly 8 to ensure welding accuracy. The two ends of the positioning plate 31 of this embodiment are respectively provided with guide holes 34, and the positioning plate 31 is matched with the guide rod 4 base shaft through the guide hole 34. The positioning plate assembly 3 can slide along the guide rod 4 in the B direction.

[0038] Depend on Figure 1 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14It can be seen that the fixed guide rail slider assembly 5 of this embodiment is installed on the inner side of the positioning plate assembly 3, which is an automatic elastic return mechanism for positioning the diverter assembly 8 in the A direction (axial direction). The fixed guide rail slider assembly 5 and the positioning plate assembly 3 are a set of inclined wedge slider mechanisms. In this embodiment, the fixed rail slider assembly 5 is composed of a slider 51, a fixed rail 52, a baffle 53, a return spring 54 and an insulating compression piece 55; the slider 51 and the fixed rail 52 are both trapezoidal, and the inclined side of the slider 51 corresponds to the positioning plate 31. The slider 51 is provided with a slide groove 56, one end of the slide groove 56 is provided with a baffle 53, and the other end is installed with an insulating compression piece 55. The return spring 54 and the fixed rail 52 are installed in the slide groove 56 between the baffle 53 and the insulating compression piece 55; the fixed rail slider assembly 5 and the positioning plate assembly 3 are a set of inclined wedge slider mechanisms. When the positioning plate assembly 3 moves in the B direction, it drives the fixed rail slider assembly 5 to slide along the A direction, so that the diverter assembly 8 is compressed and limited in the A direction. In this embodiment, the slider 51 and the fixed rail 52 are both trapezoidal iron blocks.

[0039] Depend on Figure 1 , Fig.15 , Fig.16 , Fig.17 It can be seen that the shunt assembly 8 of this embodiment is composed of a shunt 81 and a strong current terminal 82. The shunt 81 and the strong current terminal 82 are formed by brazing, and a round hole 83 is provided on the strong current terminal 8, and the copper electrode 23 of this embodiment matches the round hole 83.

[0040] In this embodiment, the insulating bottom plate 9 is fixedly mounted on the welding tooling bottom plate 1 on one side of the connecting plate assembly 2 by bolts, and one end of the movable rod 71 of the quick clamp 7 is fixed to the positioning plate assembly 3 by bolts, and the other end is fixed to the insulating bottom plate 9 by bolts. In this embodiment, by pulling the handle 72 on the quick clamp 7, the positioning plate assembly 3 is driven to slide along the B direction through the movable rod 71. Since the positioning plate assembly 3 and the fixed guide rail slider assembly 5 are a set of inclined wedge slider mechanisms, the fixed guide rail slider assembly 5 is driven to slide along the A direction, and then the diverter assembly 8 is pressed and limited in the A direction, so that the diverter assembly 8 installed in the positioning plate assembly 3 is respectively positioned in the B direction (radial) and the A direction (axial) to ensure welding accuracy. Compared with previous welding products, the high-precision diverter welding tooling of the present embodiment has a simple structure, consisting of a single iron block with a weldment groove, which is inconvenient to operate and has very low safety and stability. Overheating often occurs after a long welding time, which can easily cause deformation of the tooling and welding damage, and cause large fluctuations in the size of the weldment product. The tooling structure of the present embodiment is provided with a cooling water trough and an insulating plate, which has fast heat dissipation, simple operation and high safety. At the same time, the positioning plate assembly is provided with a ball screw and an automatic elastic return mechanism to ensure that the weldment and the tooling are flexibly pressed and accurately positioned, thereby ensuring high welding accuracy, and there will be no quality problems even after long-term work, and the replacement time of the welding product is greatly reduced, thereby greatly improving the welding efficiency.

[0041] The above descriptions are merely embodiments of the present invention and do not constitute any limitation to the present invention. Any simple modifications, changes and equivalent method variations made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
