Description
Technical Field
[0001] The utility model belongs to the technical field of automobile assembly tools, and in particular relates to an assembly auxiliary device compatible with pure electric vehicles and fuel vehicles. Background Art
[0002] Cars are an indispensable means of transportation in people's daily lives. In recent years, my country's new energy vehicle industry has developed rapidly. At present, my country has stood at the top of the world's new energy vehicle manufacturing. With the popularity of new energy vehicles, traditional fuel vehicle companies are also constantly transforming. Since new energy vehicles contain battery packs and motors, and some hybrid models have both motors and fuel engines, the structure of the chassis of new energy vehicles is different from that of traditional fuel vehicles, and its production process is also quite different from that of traditional fuel vehicles, which has an impact on the transportation and assembly of the chassis. For example, the rear axle assembly production line of traditional fuel vehicles can assemble the chassis rear axle of electric vehicles, but there is no corresponding supporting tooling, and the drive motor cannot be further assembled. The electric vehicle chassis with the rear axle assembled needs to be transported to the corresponding supporting tooling of the production line specially established for assembling the drive motor. The process is time-consuming and labor-intensive. At the same time, the latter process waits for the previous process, resulting in waste of personnel, materials, and resources, resulting in reduced production efficiency, and increasing the cost of new equipment, which hinders the transformation of traditional fuel vehicle production lines.
