[0030] Two long-side outer frames 1 and two short-side outer frames 2 are welded end-to-end to form a rectangular outer frame, and four uprights 3 are welded to the corners of the rectangular outer frame. The two ends of the long support bars 4 are welded to the two short-side outer frames 2, and the three long support bars 4 and the two long-side outer frames 1 are arranged side by side with equal spacing.

[0031] The twelve first short support bars 5 are divided into three groups, with four first short support bars 5 in each group. One end of the first short support bar 5 is welded to the first long support bar 4, and the other end is welded to the adjacent long support bar 4 or the long side of the outer frame 1. The four first short support bars 5 in a single group are located in a straight line, and the three groups of first short support bars 5 are arranged side by side with equal spacing. The first short support bar 5 located between two groups of first short support bars 5 is located in the middle of the rectangular outer frame.

[0032] The eight second short support bars 6 are divided into two groups, with four second short support bars 6 in each group. Each group of second short support bars 6 is located between two adjacent groups of first short support bars 5. One end of the second short support bar 6 is welded to the first long support bar 4, and the other end is welded to the adjacent long support bar 4 or the long side outer frame 1.

[0033] The four third short support bars 7 are divided into two groups, with two third short support bars 7 in each group. Each group of third short support bars 7 is located between the first short support bar 5 and the second short support bar 6. One end of the third short support bar 7 is welded to the first long support bar 4, and the other end is welded to the long side outer frame 1.

[0034] The bottoms of the long outer frame 1, the two short outer frames 2, the support leg 3, the long support bar 4, the first short support bar 5, and the second short support bar 6 are all on the same horizontal plane. The tops of the long outer frame 1, the two short outer frames 2, the long support bar 4, the first short support bar 5, the second short support bar 6, and the third short support bar 7 are all on the same horizontal plane. The top of the support leg 3 extends vertically upwards, and the bottom of the third short support bar 7 is higher than the bottom of the long outer frame 1, the two short outer frames 2, the support leg 3, the long support bar 4, the first short support bar 5, and the second short support bar 6.

[0035] Specifically, there are multiple L-shaped irons 8, and each L-shaped iron 8 needs to be welded onto three long support bars 4.

[0036] This embodiment provides an L-shaped iron positioning and welding fixture for a battery clamping platform, used to perform positioning welding on the aforementioned L-shaped iron 8.

[0037] refer to Figure 2 , Figure 3 and Figure 4 A battery clamping platform L-shaped positioning and welding fixture includes: a positioning plate 9, the length and width of which are the same as those of a long support bar 4. One or both sides of the positioning plate 9 have multiple positioning mounting plates 10, each with mounting holes through which mounting bolts 11 are threaded.

[0038] A height-limiting square tube 12 can be fixedly connected to the side of the positioning mounting plate 10 near the positioning plate 9 to limit the height of the L-shaped iron 8 on the long support bar 4. If the positioning mounting plate 10 has a limiting square tube, the mounting bolt 11 should be of a longer specification.

[0039] A battery clamping platform L-shaped positioning welding fixture further includes a rectangular tube 13, the length and width of which are the same as those of the positioning plate 9. The rectangular tube 13 is fixedly connected to the positioning plate 9, and the rectangular tube 13 is used to increase the thickness of the positioning plate 9 so that the positioning plate 9 can be fixed to the long support bar 4 by a clamp.

[0040] In an optional embodiment of this application, reference is made to Figure 5 There are nine positioning mounting plates 10 on a positioning plate 9, with six positioning mounting plates 10 on one side of the positioning plate 9 and three positioning mounting plates 10 on the other side of the positioning plate 9. A limit square tube is provided on one of the three positioning mounting plates 10 on one side of the positioning plate 9.

[0041] In an optional embodiment of this application, reference is made to Figure 5 The other positioning plate 9 has six positioning mounting plates 10, which are located on one side of the positioning plate 9.

[0042] In an optional embodiment of this application, reference is made to Figure 5 Furthermore, there are seven positioning mounting plates 10 on each positioning plate 9, with six positioning mounting plates 10 on one side of the positioning plate 9 and one positioning mounting plate 10 on the other side. Only one positioning mounting plate 10 on one side of the positioning plate 9 is equipped with a limiting square tube.

[0043] The implementation principle of the L-iron positioning and welding fixture of the battery clamping platform in this application is as follows: Before welding the L-iron 8, three positioning plates 9 are fixed on three long support bars 4 respectively. Then, multiple L-irons 8 are fixed with multiple mounting bolts 11 so that the L-irons 8 are tightly attached to the long support bars 4. Finally, the L-irons 8 are welded. Because the L-irons 8 are positioned during the welding process, the welding accuracy of the L-irons 8 can be effectively improved.
