Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a frame positioning welding fixture for a battery clamping platform. Background Technology

[0002] With the continuous development of new energy vehicles, battery upgrades are becoming more frequent, and the types of batteries are becoming increasingly diverse. During battery production, battery clamping platforms are needed as transport vehicles.

[0003] Due to the frequent updates and variety of battery types, the layout of battery clamping platform production lines often needs to be adjusted, resulting in high costs for automated production of battery clamping platforms. Therefore, most manufacturers choose to use manual welding.

[0004] During the welding process of the battery clamping platform, the frame needs to be welded first. The structure of the frame can be referenced. Figure 1 Currently, the frames are typically placed manually according to the dimensions on the drawings, marked with lines, and then welded in place by hand. Each frame component is welded and fixed according to this process. If the placement of a frame component is incorrect, it will affect the overall welding accuracy and subsequent assembly processes. If the welding accuracy does not meet the requirements, at best it will require disassembling and re-welding the individual frame component, and at worst it will render the entire frame unusable.

The cross-section of the square tube is rectangular, and the two adjacent sides of the rectangle are perpendicular, which can better facilitate positioning.

[0043] The implementation principle of the frame positioning welding fixture for a battery clamping platform according to an embodiment of this application is as follows:

[0044] When welding the frame, refer to Figure 3First, weld the two long-side outer frames 1, the two short-side outer frames 2, and the four uprights 3. Specifically, first place the frame positioning welding fixture on a flat surface. Place the long-side outer frames 1 at the ends of the three short-side support square tubes 9 and tightly against the three second positioning columns 14. Place the short-side outer frames 2 at the ends of the three long-side support square tubes 8 and tightly against the first positioning column 13. At this point, the short-side support square tubes 9 can support the long-side outer frames 1, the long-side support square tubes 8 can support the short-side outer frames 2, the second positioning columns 14 can position the long-side outer frames 1, and the first positioning columns 13 can position the short-side outer frames 2. Then, tightly attach each upright 3 to the end of the adjacent long-side outer frame 1 and short-side outer frame 2, and weld after confirming that everything is correct.

[0045] Then, weld three long support bars 4. Specifically, place the three long support bars 4 on the three long-side support square tubes 8 respectively. At this time, the long-side support square tubes 8 can support the long support bars 4, and the long support bars 4 are located between multiple third positioning columns 15, which can position the long support bars 4. After confirming that everything is correct, weld the long support bars 4.

[0046] Next, weld twelve first short support bars 5. Specifically, place the twelve first short support bars 5 on three short-side support square tubes 9 respectively. At this time, the short-side support square tubes 9 can support the first short support bars 5. Depending on the position of the first short support bars 5, the second positioning column 14 and the third positioning column 15 can position the first short support bars 5, or the two third positioning columns 15 can position the first short support bars 5. After confirming that everything is correct, weld the first short support bars 5.

[0047] Next, weld eight second short support bars 6. Specifically, place the eight second short support bars 6 on either the first reinforcing support square tube 10 or the second reinforcing support square tube 11, which will support the second short support bars 6. The first short support bars 5 placed on the first reinforcing support square tube 10 are positioned by two fourth positioning columns 16, and the second short support bars 6 placed on the second reinforcing support square tube 11 are positioned by two fifth positioning columns 17. After confirming that everything is in order, weld the second short support bars 6.

[0048] Finally, weld the four third short support bars 7. Specifically, place the four third short support bars 7 on the four raised support square tubes 12 respectively. The raised support square tubes 12 can support the third support bars, and the two sixth positioning columns 18 can position the third support bars. After confirming that everything is correct, weld the third short support bars 7.

[0049] In the above process, each part of the frame is supported or positioned by corresponding tooling, which effectively improves the welding accuracy of the frame. Furthermore, once the positioning is accurate, welding can be switched from manual to robotic, increasing efficiency.
