Description

Technical Field

[0001] This utility model relates to the field of electric vehicle assembly technology, specifically to an electric four-wheeled vehicle frame assembly. Background Technology

[0002] The processing quality of the electric four-wheeled vehicle frame is crucial to the overall performance of the vehicle. However, the traditional processing method has significant drawbacks. Traditionally, a flat welding table is used to place and weld the frame components, which has poor processing efficiency. Due to the lack of efficient clamping devices, it is difficult to quickly and accurately fix the frame body, which leads to repeated adjustments of the position of each component during assembly, thus prolonging the processing cycle. In order to improve the efficiency of frame processing, simple jigs are currently used to clamp and weld the frame. However, traditional jigs are mostly fixed and have a single clamping method. They are not well adapted to frames with complex geometries and are prone to frame deformation and positioning deviations during welding or assembly. This not only increases rework costs but may also affect the structural strength of the entire vehicle. At the same time, it is difficult to meet the assembly requirements of the frame integrating multi-functional components such as battery support and rear cover.

[0003] Therefore, while some existing electric four-wheel vehicle frame processing fixtures can improve stability to a certain extent, they generally suffer from defects such as insufficient dynamic adjustment capability, poor clamping effect on curved or irregular structures, and low functional integration.

[0047] The surfaces of the connecting bracket 53 and the connecting base 54 are used to achieve limiting.

[0048] In practical use, the first step is: processing the frame of the electric four-wheeled vehicle;

[0052] The clamp 26 clamps the top of the frame to prevent it from falling. The frame is then assembled according to the driver's seat frame 37 of the electric four-wheeled vehicle, which restricts the four-wheeled vehicle frame. The frame is then limited by the base 34 and the cover strip 35, and the position of the corresponding outer frame 32 is also limited, thus achieving the assembly of the four-wheeled vehicle frame.
