Clamping device for square lithium battery performance test

Abstract

The utility model relates to a clamping device used for a square lithium battery performance test, comprising a frame assembly and a clamping mechanism, the frame assembly comprises a frame main body, the frame main body is provided with a mounting plate, and the mounting plate is provided with the clamping mechanism and a test lithium battery; the top surface of the frame main body is provided with a front third transverse profile and a rear third transverse profile which are arranged in parallel, and the third transverse profiles are used for integrating cable fixing blocks; the fixing block is used for sleeving a positive electrode test wire or a negative electrode test wire; the clamping mechanism comprises a clamping air cylinder, a pneumatic connector, clamping plates and heat dissipation plates, the two ends of the clamping air cylinder are each connected with one clamping plate, the opposite inner sides of the two clamping plates are each fixedly connected with one heat dissipation plate, and a tested lithium battery is arranged between the two heat dissipation plates. According to the utility model, the falling risk caused by unstable placement in the test process of the lithium battery is effectively eliminated, heat generated by the lithium battery in the test process can be quickly conducted out through the heat dissipation plate, the heat dissipation efficiency is improved, and the safety and reliability of the whole test process are improved.
