Embodiment
As shown in Figure 5 and Figure 6, a kind of device for the battery core thickness for measuring electrokinetic cell of the present invention, including housing, the shell
Body is open type housing, and in present embodiment, housing is enclosed and formed by upper mounting plate 3, column 5, riser 7 and bottom plate 8；The bottom
The bottom of plate 8 is fixed with lower margin 9.So make it that integral structure layout is reasonable, and rigidity can bear the weight of whole test device
With caused accidental vibration in cylinder running.The case inside bottom is fixed with insulation 10 plates of pressure, the insulation pressure
The top of plate 10 is provided with top board 6 moving up and down, and the top of top board 6 is connected with elevating mechanism；The top board 6
Top is also associated with stretching out the digital display dial gauge 1 of housing.
Further, the elevating mechanism includes the slide rail 14 being fixed on case inside wall, and the top of top board 6 is consolidated
Surely there is sliding block installing plate 13, sliding block 12 is fixed with the sliding block installing plate 13, the sliding block 12 is slidably connected with slide rail 14；Institute
The top of top board 6 is stated with the top of cylinder 16 to be connected.Pressure sensor is provided between the cylinder 16 and top board 6, it is described
Hull outside is fixed with pressure reading display.
Further, reversal valve 15 is fixed with the housing, pneumatic triple piece 4 is further fixed on the housing.This hair
The bright purification for entering the laggard promoting the circulation of qi body of pneumatic triple piece 4 through piping using 0.4-0.8Mpa compressed airs, it is adjusted to required
Pressure limit 0.4 (+0.04, -0.04) Mpa in the range of, and the compressed air after atomization is controlled by reversal valve 15
Pressing plate 6 move up and down or pressurize makes top board 6 fixed.
The operation principle of the present invention is as follows：Reversal valve 15 is transferred to left side before testing, declines top board 6, is bonded
Insulating press boards 10, while digital display dial gauge 1 is zeroed.Then reversal valve 15 is transferred to right side, top board 6 is risen to greatly
