Description

Technical Field

[0001] The utility model relates to the technical field of torque measurement of battery cover plates, in particular to a battery cover plate pole torque measurement tool. Background Art

[0002] The battery cover is the best line of defense for the single battery. The cover connects the winding core and the external energy system. Once the battery cover is damaged, the safety performance of the battery cannot be guaranteed. Therefore, it is particularly important to scientifically test the battery cover. As we all know, the cover includes a lower insulating member and a cover body. The cover body is provided with a pole assembly. The pole assembly includes an upper insulating member installed on the cover body and a pole installed on the upper insulating member. The upper insulating member 1 (such as Figure 1-Figure 2 The torque value parameter of the terminal test item is to ensure the ability of the single-cell battery to resist external mechanical vibration after being assembled. Therefore, the importance of scientifically and rationally testing the torque value of the cover terminal is self-evident. Currently, most battery manufacturers do not have a set of standardized test standards for torque testing, and there are relatively many test methods. For example, it is necessary to place the top cover in the slot and then turn the rocker to lock it. This process is time-consuming and the torque test value is not accurate. In addition, torque testing is a destructive experiment. The cover is destroyed immediately after the torque is measured, which is a waste of money.

[0003] After searching, the Chinese patent with the authorization announcement number CN 218916622U and the name "A riveted top cover pole torque test tool" discloses a method of limiting the two sides of the rectangular top cover by using a blocking block. However, the shortcoming of this patent is that it cannot achieve the limitation of the upper surface of the cover, which affects its detection accuracy to a certain extent. Utility Model Content
