However, in this process, since the pressure plate and the thickness measuring assembly to which the pressure plate belongs have a large dead weight, in order to prevent the battery from being crushed, the applied pressure range needs to be reduced, resulting in a reduction in the accuracy of thickness measurement.
Based on the above, the utility model provides a rack of a battery pressurizing thickness measuring device. Referring to fig. 1 and 2, the frame of the battery pressurizing thickness measuring device comprises a bracket 1 and a support column 2, wherein the bracket 1 and the support column 2 are fixedly arranged, the support column 2 comprises two parts, the two parts are respectively arranged along the vertical direction and symmetrically arranged on the inner sides of the left side and the right side of the bracket 1, a thickness measuring mechanism 4 is arranged on the bracket 1 in a liftable manner, a battery 5 is arranged below the thickness measuring mechanism 4, and the thickness measuring mechanism 4 is contacted with the top surface of the battery 5 after moving downwards and applies pressure.
Specifically, in this embodiment, the frame 1 of the battery pressurizing and thickness measuring device has a gantry structure, which is fixedly installed on a large frame plate (not shown), guide rail pairs 11 are disposed on the left and right sides of the frame 1, and two sides of the thickness measuring mechanism 4 are respectively installed on the guide rail pairs 11 on the two sides, so as to realize lifting movement.
The support columns 2 are provided with elastic pieces 21, the elastic pieces 21 are arranged in the vertical direction, and the elastic pieces 21 on the two support columns 2 are symmetrical to each other. The thickness measuring mechanism 4 moves downwards to contact with the elastic piece 21, and compresses the elastic piece 21 to generate a vertical upward supporting force.
According to the frame of the battery pressurizing and thickness measuring device, when pressurizing and thickness measuring are carried out, the two sides of the thickness measuring mechanism 4 synchronously move downwards, the elastic pieces 21 arranged on the support columns 2 at the two sides are compressed, upward supporting force is generated after the elastic pieces 21 are compressed, the dead weight of the thickness measuring mechanism 4 is counteracted, the pressure range capable of being applied to a battery is enlarged, and therefore more accurate thickness data of the battery 5 are measured.

The design in which the mounting block 22 protrudes inward of the bracket 1 can reduce the width of the support posts 2 on the left and right sides, as compared with the case where the elastic member 21 is directly provided on the support posts 2, thereby forming a larger space between the two support posts 2 to accommodate the larger-sized battery 5 and the lower pressure plate to load the battery 5.
In a preferred embodiment, the frame of the battery pressure gauge also includes a briquette 3. Referring to fig. 2 and 3, the pressing block 3 includes two elastic members 21 respectively provided at both sides, that is, the elastic members 21 form a support for the pressing block 3.

On the other hand, the first and second protrusions 222 and 33 can also function to limit the position of the elastic member 21, further reducing the possibility of the elastic member 21 coming off from between the pressing block 3 and the mounting block 22.
