Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a PU mounting base 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, after the frame is welded, a PU (Polyurethane) mounting bracket needs to be welded onto the frame. Please refer to [reference needed] for the specific location of the PU mounting bracket on the frame. Figure 1 Currently, PU mounting brackets are typically installed manually according to the dimensions shown in the drawings, measured in the actual locations, and then manually welded in place. If a PU mounting bracket is placed incorrectly, it will affect the overall welding accuracy and subsequent assembly processes. If the welding accuracy is insufficient, at best the PU mounting bracket will need to be removed and re-welded; at worst, the entire mounting platform will be scrapped. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a PU mounting base positioning welding fixture for a battery clamping platform, which can position the PU mounting base during the welding process and effectively improve the welding accuracy of the PU mounting base.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model provides a PU mounting base positioning and welding fixture for a battery clamping platform, comprising: two first connectors, two second connectors, and two positioning plates; one end of one of the first connectors is disposed at one end of one of the second connectors, and the other end is disposed at one end of the other second connector; one end of the other first connector is disposed at the other end of one of the second connectors, and the other end is disposed at the other end of the other second connector; the two first connectors are parallel to each other, and the two second connectors are parallel to each other; the two positioning plates are horizontally disposed on opposite sides of the two second connectors, and a positioning opening is provided on the end of the positioning plate near one of the first connectors.

[0008] By adopting the above technical solution, before welding the PU mounting base, this fixture is first fixed to the frame, ensuring the second connector aligns with the third short support bar. Then, the PU mounting base is positioned using the positioning opening. Finally, after confirming the PU mounting base is correctly positioned, it is welded onto the third short support bar. In this process, because the PU mounting base is positioned using the positioning opening, the welding accuracy of the PU mounting base is effectively improved.

[0009] Optionally, the positioning plate is fixedly connected to the first connecting member.

[0010] By adopting the above technical solution, the stability of the positioning plate can be improved, and the first connecting member can also position the positioning plate, thereby improving the positioning accuracy of the positioning plate.

[0011] Optionally, both the first connector and the second connector are made of square tubing.

[0012] By adopting the above technical solution, the cross-section of the square tube is rectangular, which can better achieve a precise connection between the two.

[0013] In summary, this utility model has at least the following beneficial technical effects:

[0014] By using the PU mounting base positioning welding fixture of this battery clamping platform, the PU mounting base can be positioned during the welding process, thereby effectively improving the welding accuracy of the PU mounting base. Attached image description:
