Problems solved by technology

Although this method has a simple structure, it cannot guarantee the accuracy of the position of the side plate of the module, nor can it guarantee the uniform force during the tensile test, and the clamp cannot clamp the side plate of the module when it is clamped. The center position of the side plate, so the error of the test result is very large, and sometimes even loses the meaning of measurement; on the other hand, because the pressure plate often only presses a part of the side plate of the module, the test result will also be inaccurate. It will also cause the possibility of breaking the module side panel shell directly

Abstract

The invention provides a device for a power battery module side plate tensile test. The device comprises a base and a compression assembly. The base is fixed to a test table and provided with a threaded hole. The compression assembly comprises a vertically-arranged screw rod and a pressing plate horizontally installed at the lower end of the screw rod. The upper end of the screw rod penetrates out of the threaded hole, and the screw rod is in threaded connection with the threaded hole. The pressing plate is located between the base and the test table. The pressing plate can rotate along with the screw rod in the threaded hole so as to move up and down. The device is fixed to the test table and can accurately fix and press a power battery module, and accuracy of the tensile test can be greatly improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a device for tensile testing the side plate of a power battery module. Background technique [0002] my country is currently in the period of vehicle energy conversion, and new energy vehicles are increasing day by day. In major enterprises, the safety of new energy vehicles has attracted more and more attention. As the power source of new energy vehicles, the power battery module is self-evident, so it is necessary to carry out safety inspections on all parts of the power battery module to ensure that it meets the safety standards when it leaves the factory. In the various tests of the power battery module, it is necessary to conduct a tensile test on the welding performance of the side plate of the module. Usually, it is necessary to cut off the side plate of the module, and only keep one side plate. The L-shaped weldment formed by welding the plate and an end plate is used as...
