Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a positioning welding fixture for a pin mounting base of 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, pin mounting brackets need to be welded onto the frame. Please refer to [reference needed] for the specific location of the pin mounting brackets on the frame. Figure 1 Currently, the pin mounting brackets are typically installed manually according to the dimensions on the drawings, measured and placed in their corresponding positions, and then manually welded in place. If any pin mounting bracket is misplaced, it will affect the overall welding accuracy and subsequent assembly processes. If the welding accuracy is insufficient, the pressure pin may not press down on the battery pack, failing to achieve the desired clamping effect. This can result in anything from requiring the pin mounting bracket to be disassembled and re-welded to rendering the entire clamping platform unusable. Utility Model Content

[0005] The present invention aims to provide a positioning welding fixture for a pin mounting base of a battery clamping platform, which can position the pin mounting base during the welding process and effectively improve the welding accuracy of the pin mounting base.

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

[0007] This utility model provides a pin mounting base positioning welding fixture for a battery clamping platform, comprising: four positioning bases, two connecting square tubes, and two positioning plates; the four positioning bases are divided into two groups, and each group consists of two positioning bases. The two positioning bases in a single group are respectively fixedly connected to the two ends of a single connecting square tube on the same side. One end of the positioning plate is fixedly connected to one end of one connecting square tube, and the other end is fixedly connected to one end of the other connecting square tube. The connection positions of the positioning plate and the connecting square tube, and the connection positions of the positioning base and the connecting square tube, are on the same side of the connecting square tube. Positioning slots are respectively opened on the opposite sides of the two positioning plates.

[0008] By adopting the above technical solution, before welding the pin mounting base, the positioning welding fixture for the pin mounting base of this battery clamping platform is first placed on the mounting plate. The position of the positioning welding fixture is adjusted so that the positioning base positions the two connecting square tubes on the positioning base, thereby positioning the two positioning plates and determining the position of the positioning slot. Then, under the positioning of the positioning slot, the pin mounting base is welded to the mounting plate. This achieves positioning of the pin mounting base during the welding process, effectively improving the welding accuracy of the pin mounting base.

[0009] Optionally, the positioning seat includes a first positioning square tube and a second positioning square tube, the length of the first positioning square tube is shorter than the length of the second positioning square tube, the first positioning square tube and the second positioning square tube are fixedly connected side by side, and the ends of the first positioning square tube and the second positioning square tube are fixedly connected to the connecting square tube.

[0010] By adopting the above technical solution, before welding the pin mounting base, the positioning welding fixture for the pin mounting base of this battery clamping platform is first placed on the mounting plate. The position of the positioning welding fixture is adjusted so that the first positioning square tube is positioned on the long support bar, and the side of the second positioning square tube closest to the first positioning square tube contacts the long support bar, while the adjacent side contacts the second short support bar. At this point, the first and second positioning square tubes can position the location of the positioning plate, thereby determining the position of the positioning slot. Then, under the positioning of the positioning slot, the pin mounting base can be welded to the mounting plate. This achieves positioning of the pin mounting base during the welding process, effectively improving the welding accuracy of the pin mounting base.

[0011] Optionally, the positioning slot is located in the middle section of the positioning plate.

[0012] Optionally, the positioning slot is located at one end of the positioning plate near one of the connecting square tubes.

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

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