AI Technical Summary
Technical Problem
[0004]由于常见的夹持模块多采用恒压夹持的方式，即检测过程中，夹持模块对上盖边缘的夹持力度保持恒定；由于对着注气模块的动作，上盖内部的气压会越来越大，最终会使上盖出现变形；而上盖变形过程中，会牵拉上盖边缘，使上盖边缘有位移、变形的趋势；采用恒压夹持的方式进行夹持时，其压力值过大会导致橡胶密封垫片变形过大，可能会使橡胶密封垫片损坏，从而导致检测过程中出现漏气现象；而压力值过小又会出现夹持力不足的情况，检测过程中也会出现漏气现象；而压力值采用适中值，一方面中值需要通过多次实验得出；另一方面，随着上盖变形量增大，上盖边缘位移变形的趋势也会增大，会使得夹持模块的夹持的约束效果降低，最终导致夹持失效而影响检测精度
Benefits of technology
[0012]与现有技术相比，本实用新型的有益效果是：上盖内气压的不断增加，通过调节件不断增加夹持板与检测台对上盖边缘的挤压力度（增大橡胶密封垫片的变形量）；能够在上盖内外压力差较大时避免空气从边缘泄露而降低检测精度，且通过随内部压力增加而增加橡胶密封垫片变形量的方式，能够避免初始夹持时过高的夹持力导致橡胶密封圈受损，而影响检测精度，也能在上盖变形时，通过提高夹持力度的方式，提高对上盖边缘的约束效果，避免夹持失效。

Abstract
The utility model relates to a kind of strength detection devices, specifically a kind of energy storage battery box sealing upper cover strength detection device, including installation frame;Air pump is installed on installation frame;Further include detection frame;Detection table, multiple groups of air inlet valve are installed on detection table;Clamping part, including the clamping plate that can be close to or away from detection table along vertical direction;Further include adjusting part;With the increasing of the air pressure in upper cover, the extrusion degree of clamping plate and detection table to the edge of upper cover (increase the deformation amount of rubber sealing gasket) is constantly increased by adjusting part;It can avoid air leakage from edge to reduce detection accuracy when the pressure difference between upper cover inside and outside is larger, and by the way of increasing the deformation amount of rubber sealing gasket with the increase of internal pressure, it can avoid that the rubber sealing ring is damaged due to too high clamping force when initial clamping, and affect detection accuracy, also can improve the restraint effect to the edge of upper cover by improving clamping force when upper cover deformation, avoid clamping failure.
