Description

Technical Field

[0001] The utility model relates to the technical field of locking piece welding, and in particular to a welding fixture for a battery swap base locking assembly. Background Art

[0002] Heavy trucks have a large load capacity, high fuel consumption and huge emissions, so there is an urgent need for electrification. For the electrification solution for heavy trucks, battery replacement is the first choice rather than fast charging. This is because the battery capacity of heavy trucks is too large. If fast charging is used as a solution, the charging power cannot be supported. Therefore, it is necessary to quickly replace the heavy truck battery through the locking assembly. The existing welding fixture of the battery replacement base locking assembly requires the cooperation of multiple workers to realize the assembly line operation of the locking assembly welding, which requires high labor costs. As the welding workload increases, the workers' physical strength is greatly consumed, and the corresponding processing hours will be extended, which makes the welding quality of the locking assembly unable to be guaranteed.
