Embodiment
As shown in Figure 5 and Figure 6, a kind of device for the battery core thickness for measuring electrokinetic cell of the utility model, including housing, institute It is open type housing to state housing, and in present embodiment, housing is enclosed and formed by upper mounting plate 3, column 5, riser 7 and bottom plate 8;Institute State the bottom of bottom plate 8 and be fixed with lower margin 9.So make it that integral structure layout is reasonable, and rigidity can bear whole test device Caused accidental vibration in weight and cylinder running.The case inside bottom is fixed with insulation 10 plates of pressure, described exhausted The top of edge pressing plate 10 is provided with top board 6 moving up and down, and the top of top board 6 is connected with elevating mechanism;On described The top of pressing plate 6 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 reality With the new 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 In the range of required pressure limit 0.4 (+0.04, -0.04) Mpa, and the compressed air after atomization is controlled by reversal valve 15 Top board 6 processed move up and down or pressurize makes top board 6 fixed.
Operation principle of the present utility model is as follows:Reversal valve 15 is transferred to left side before testing, declines top board 6, is pasted Insulating press boards 10 are closed, while digital display dial gauge 1 is zeroed.Then reversal valve 15 is transferred to right side, top board 6 is increased To more than the thickness optional position of battery core 11, pressure reading display 2 is zeroed, while battery core 11 is put into insulating press boards 10 Correct position.Adjustable change valve 15 arrives left side, declines top board 6, after top board 6 is fully pressed to battery core 11, by reversal valve 15 are transferred to centre position pressurize, after keeping 5s stable, while record the concrete numerical value and digital display dial gauge of pressure reading display 2 1 reading.The reading of digital display dial gauge is thickness when keeping measuring battery core cold pressing during 0.4Mpa compressed airs.In the present apparatus When initial stage tries out, the checking of data applicability is tested to the present apparatus.The thickness range of half battery core be 12.6 (+0.5 ,- 0.5) mm, the thickness range of full battery core is 25.2 (+0.5, -0.5) mm.Table 1 below represents electric under different compressed air operating modes The pressure and thickness change situation that core is born.
As depicted in figs. 1 and 2, different types of battery core is under different compressed air operating modes, the pressure sensing recorded The weight registration of device changes in the same direction, and shows linear change.As shown in Figure 3 and Figure 4, the thickness of half battery core has been absolutely proved It is 12.6 (+0.5, -0.5) mm to meet scope, and the thickness of full battery core meets that scope is 25.2 (+0.5, -0.5) mm.Generally exist 0.4Mpa up starts, and the registration of thickness increasingly tends to consistent from basic value, and tolerance is constantly reducing.
Although the foregoing describing specific embodiment of the present utility model, those skilled in the art should manage Solution, these are merely illustrative of, and various changes or modifications can be made to present embodiment, without departing from original of the present utility model Reason and essence, the scope of protection of the utility model are only limited by the claims that follow.
