Description

Technical Field

[0001] The utility model relates to the field of battery liquid cooling plate processing, and specifically relates to a welding jig with self-clamping function. Background Technique

[0002] A battery liquid cooling plate is a device that uses liquid for heat dissipation, usually using liquids such as water and ethylene glycol for circulating heat dissipation. In electric vehicles, the battery is the core component. It undergoes a large amount of charging and discharging, generating a large amount of heat. If this heat cannot be dissipated in time, the temperature of the entire battery system will rise, having a negative impact on the system operation. The battery liquid cooling plate keeps the battery temperature within an appropriate range by flowing the coolant through the battery surface. During the processing of the battery liquid cooling plate, workers usually use welding jigs for auxiliary work.

[0003] However, the current welding jigs still have some deficiencies. For example, a multi-station and quickly-coolable battery liquid cooling plate welding device with the application number 202320431268.5 has not comprehensively considered the self-clamping structure of the welding jig. During the use of the welding jig for processing the battery liquid cooling plate, if the self-clamping structure of the welding jig is not comprehensively considered, manual clamping and fixing of the battery liquid cooling plate will greatly affect the work efficiency of the workers. Moreover, the clamping may not be tight enough, resulting in accidental deviation during the subsequent processing of the battery liquid cooling plate, which is not convenient for the workers to use the welding jig.
