Description

Technical Field

[0001] The invention relates to the technical field of automobile scale assembly, in particular to a modular automobile scale lap joint assembly platform. Background Art

[0002] Traditionally, in the production of automobile scale lap joints, manual assistance for leveling and manual welding are used. However, this not only requires a large amount of manpower expenditure, but also the lap joint accessories are relatively heavy. Even if multiple workers can temporarily assist in fixing them, once one person's strength is not controlled well, product deviation will occur. In severe cases, the lap joint accessories will fall and injure the operator. Moreover, the processing accuracy of the automobile scale lap joint has a decisive influence on the measurement accuracy of the automobile scale product. In the past, the production accuracy of the scale lap joints was controlled by manual measurement, which often had large errors and was not suitable for mass production, affecting production efficiency. Summary of the invention
