Abstract

[0002] The motorcycle frame assembly line is the core component of the motorcycle. It supports the engine, provides a fixed position for the steering mechanism and rear shock absorber, bears the weight of the rider, passengers and luggage, and provides a mounting position for components such as the fuel tank and battery.
[0003] Most motorcycle frame assembly lines use complex pipe and plate welding structures, which are the supporting skeleton of the motorcycle. During the welding and assembly process, accurate positioning can ensure that the various components of the frame are connected according to the design requirements, thereby ensuring the accuracy and stability of the frame structure. If the positioning is inaccurate, it may cause problems such as frame deformation and component misalignment, which in turn affects the driving stability and safety of the motorcycle.
[0004] Traditional welding positioning achieves positioning by docking the contraction part and expansion part of the end of the pipe. The dimensional accuracy of the frame depends on the dimensional management of each pipe during processing, and it is difficult to rework the frame after assembly and welding. The dimensional accuracy of the frame directly determines the accuracy of the shell installation. If there is a deviation in the size of the frame, the shell may not fit perfectly with the frame during installation, resulting in installation difficulties or gaps after installation. This not only affects the appearance of the motorcycle, but may also affect the sealing and stability of the vehicle. Summary of the invention
