Description

Technical Field

[0001] This utility model relates to welding fixtures, and more particularly to a welding fixture for flexible copper busbar connections. Background Technology

[0002] Some flexible copper busbar connections are formed by welding two copper busbars together. Currently, there are two positioning methods: one is to position them manually, and the other is to position them using tooling. For example, the flexible connection fixing tooling and friction stir welding equipment disclosed in CN215468785U can weld two straight copper busbars or two copper busbars that do not bend much in space. However, it is not suitable for welding two copper busbars that have many bends in space.

[0003] When welding two copper busbars, the two overlapping sections are not pressed tightly together, resulting in poor welding quality. The current method is to place an iron lump at the overlapping area as a clamping material. However, this clamping material is prone to abrasion on the surface of the copper busbar and can also move, affecting the welding process. Utility Model Content

[0030] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.

[0031] Example 1

[0032] A welding fixture for flexible copper busbar connections includes a base plate 1, with columns 2 mounted at both ends of the base plate 1. Support frames 3 are mounted on the columns 2 and secured to the columns 2 with screws. The sides of the support frame 3 are detachably equipped with a first support block 4 for supporting the flexible copper busbar connection and a welding seat 5 for positioning and stacking two flexible copper busbar connections. The first support block 4 and the welding seat 5 are mounted on the support frame 3 by a snap-fit ​​mechanism; that is, both the first support block 4 and the welding seat 5 have plugs, and the support frame 3 has corresponding insertion holes. The plugs and insertion holes engage to mount their respective first support blocks 4 and welding seats 5 onto the support frame 3. A clamping mechanism 6 is mounted on the support frame 3, with its clamping end positioned directly above the welding seat 5. The clamping mechanism is used to clamp the two stacked copper busbar sections, facilitating precise welding by the operator.

[0033] One end of the welding base 5 is a stacking section 51, which has a through hole 511. The through hole 511 is a square hole, which saves material and also helps dissipate heat during copper busbar welding. Support platforms 512 for supporting the flexible copper busbar connection end are provided on the sidewalls of the through hole 511. A positioning block 513 for positioning the flexible copper busbar connection is fixed to the upper surface of the stacking section 51, and the positioning end of the positioning block 513 extends towards the port of the through hole 511. In this embodiment, the number of positioning blocks 513 is one less than the number of support platforms 512.

[0034] The other end of the welding base 5 is a positioning part 52, which has a positioning groove 521 extending through both sides. The copper busbar is positioned and installed in the positioning groove 521, preventing it from wobbling during welding. One end of the positioning groove 521 opens towards the through hole 511, and the bottom surface of the positioning groove 521 is higher than the support surface of the support platform 512. The staggered arrangement of the positioning groove 521 and the support platform 512 allows two copper busbars to be stacked together. Welding base 5

[0035] The support platform 512 is triangular in shape, which allows for more space in the through hole 511 and improves heat dissipation. The positioning end of the positioning block 513 extends to the triangular support surface of the support platform 512. The projected shape of the positioning end of the positioning block 513 is trapezoidal. The trapezoidal positioning block 513 can improve the ventilation of the through hole 511 while positioning the copper busbar.

[0036] The first support block 4 is provided with a slot 41, which is used to position and support the copper busbar. The slot 41 extends through both ends of the block, and the open end of the side of the slot 41 faces the stacking part 51. The bottom surface of the slot 41 is on the same horizontal plane as the support surface of the support platform 512. The first support block 4 is used to place the lower section of the copper busbar to ensure its stability.

[0037] The side wall of the support frame 3 is also equipped with a detachable second support block 7, which is also used to support the copper busbar and ensure its stability. The upper end face of the support frame 3 is provided with a groove 31, the bottom surface of which is flush with the upper end face of the second support block 7. The end of the second support block 7 away from the support frame 3 is fixed with an upwardly protruding limiting part 71. One end of the copper busbar is supported on the support frame 3 and the second support block 7. After the copper busbar is bent, it is supported on the first support block 4 and finally enters the welding seat 5.

[0038] The clamping mechanism 6 includes a support rod 61, an extension arm 62, a guide tube 63, and a pressure rod 64. The pressure rod 64 is used to clamp two copper busbars stacked together. The support rod 61 is fastened to the support frame 3 with screws. One end of the extension arm 62 is fixed to the support rod 61, and the other end extends to the welding seat 5. The guide tube 63 is fastened to the extension arm 62 with screws, and the pressure rod 64 extends through the guide tube 63 toward the welding seat 5.

[0039] Example 2

[0040] Example 2 is basically the same as Example 1, except that the guide tube 63 has a guide groove 631 that passes through it on its side wall. The lower end of the guide groove 631 does not pass through the guide tube 63, but its upper end does. A limit shaft is fastened to the rod body of the pressure rod 64. The limit shaft is located in the guide groove 631 and moves up and down along it. The limit shaft is used to restrict the rotation of the pressure rod 64 on the guide tube 63. The pressure rod 64 can only move axially along the guide tube 63, thereby avoiding rotational friction against the end face of the copper busbar when the pressure rod 64 is pressed down.

[0041] Example 3

[0042] Example 3 is basically the same as Example 1, except that the top of the pressure rod 64 is provided with a counterweight 65. The outer diameter of the counterweight 65 is larger than the outer diameter of the guide tube 63. The counterweight 65 provides gravity and acts on the copper busbar through the pressure rod 64, so that the two stacked copper busbars can fit together tightly.
