Problems solved by technology

At present, the existing battery test fixture can only fix batteries of a specific size, and cannot fix batteries of the same type and different sizes
When the battery under test is fixed, the pressing force on the positive and negative ends of the battery is uneven, causing the battery to be squeezed and damaged, which reduces the accuracy of the battery test.

Abstract

The invention provides an adjustable cylindrical cell test clamp, comprising a clamp casing, a clamp base plate and cell compaction mechanisms. The clamp casing is uniformly provided with a plurality of positioning structures used for placing cylindrical cells, and line pass holes connected to each positioning structure and used for passing through leads; the clamp base plate is installed on the bottom of the clamp casing through bolts, and combines with the cell compaction mechanisms and the positioning structures on the clamp casing to be used for fixing cylindrical cells; the cell compaction mechanisms are arranged in the positioning structures of the clamp casing. The adjustable cylindrical cell test clamp can fix cylindrical cells of different specifications, guarantee uniform stress at two ends of a detected cell, guarantee position fixing when the cylindrical cells are in test through the clamp casing, the clamp base plate and the positioning structures on the cell compaction mechanisms, avoid cell sliding, loosening, and positive and negative electrode compressional deformation in test, and improve cell test accuracy; in addition, the adjustable cylindrical cell test clamp can enhance the heat dissipation capability in cell test, and guarantee security and accuracy in cell test.

Description

technical field [0001] The invention relates to the technical field of fixing structures, in particular to a battery test fixture for fixing cylindrical batteries. technical background [0002] Currently emerging buried-ion batteries have the characteristics of large capacity, low self-discharge rate, high specific energy, no memory effect, and good safety, and are widely used in the fields of electric vehicles and energy storage. In order to test various performances of the battery, special fixtures are required to fix the battery. Currently, existing battery test fixtures can only fix batteries of a specific size, and cannot fix batteries of the same type and different sizes. When the battery under test is fixed, the pressing force on the two ends of the positive and negative electrodes of the battery is uneven, which causes the extrusion damage of the battery and reduces the accuracy of the battery test process. Contents of the invention [0003] In view of the above ...
