Description

Technical Field

[0001] This utility model relates to the field of power battery aluminum alloy shell processing technology, specifically a positioning and clamping device for power battery aluminum alloy shell. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage industry, the performance and safety of power batteries, as core energy supply components, are crucial to end products. Aluminum alloy casings for power batteries have become the mainstream choice for power battery casings due to their lightweight, high strength, corrosion resistance and good heat dissipation performance. The precision control during casing processing directly affects the subsequent cell assembly, sealing performance and overall battery life. Among them, key processes such as the opening of holes in the terminals place stringent requirements on the positioning and clamping accuracy of the casing. In the processing of aluminum alloy casings for power batteries, the positioning and clamping device is the core equipment to ensure processing accuracy. Most existing devices can only achieve unidirectional or bidirectional clamping, making it difficult to form multi-dimensional positioning, such as left and right or front and back. During processing, the casing is prone to displacement along the unconstrained direction, resulting in fluctuations in processing accuracy. Moreover, the clamping structure is mostly of fixed specifications, which cannot flexibly adapt to different models and sizes of aluminum alloy casings for power batteries. Frequent fixture changes are required, which increases production changeover time and cost.

[0003] According to the patent application published on the Internet, a positioning drilling device for processing battery casings (authorization announcement number: CN222725514U) is described as including a "fixed plate, processing table" etc., to realize the drilling work.

[0004] Regarding the above description, the applicant believes the following issues exist: The positioning drilling device for battery casing processing uses a fixed plate and a processing table to perform drilling. When in use, the device uses a forward and reverse threaded rod to drive the positioning plate to fix the casing. During the drilling process, the generated debris will adhere to the forward and reverse threaded rod, affecting the accuracy of subsequent movement and thus affecting the fixing effect. Furthermore, it cannot fix the front and rear sides of the casing, further affecting stability. Therefore, this device needs to be improved. Utility Model Content
