Description

Technical Field

[0001] The utility model relates to the technical field of power battery module detection, in particular to a positioning tooling for power battery module detection. Background Technique

[0002] The power battery module is an important part of the power battery system. It is composed of multiple battery cells and usually includes components such as battery cells, battery management systems, casings, and heat dissipation systems. The positioning tooling for power battery module detection is a device specifically used for accurately positioning and fixing the power battery module for various performance and safety tests. In the fields of new energy vehicles and mobile power supplies, the safety and reliability of the power battery module are crucial. In order to ensure that the battery module meets the relevant standards and requirements during research and development and production, it is particularly important to use the positioning tooling for precise detection.

[0003] The existing positioning tooling has poor positioning efficiency for the power battery module. Usually, the power battery module is clamped and limited by an electric telescopic rod and a push plate, which easily leads to unstable clamping of the power battery module, reduces the detection efficiency of the power battery module, and does not have the function of buffering and protecting the power battery module. It cannot effectively eliminate the tremor impact force received during the use of the positioning tooling, reducing the practicality of the device. Therefore, we propose a positioning tooling for power battery module detection to solve this problem. Content of the Utility Model
