However, those skilled in the art may be aware that one or more detail description can be by
Omit, or can also be using other methods, component or material.In some instances, some implementation methods are not described
Or be not described later in detail.
Additionally, technical characteristic described herein, technical scheme can also in one or more embodiments arbitrarily closing
Suitable mode is combined.For a person skilled in the art, it is easy to understand with provided herein is embodiment relevant method
Step or operation order can also change.Therefore, any order in drawings and Examples is merely illustrative purposes, not secretly
Show requirement in a certain order, require unless expressly stated according to a certain order.
And " connection ", " connection " described in the application, unless otherwise instructed, including directly or indirectly connecting (connection).
Fig. 1 shows that this lead set endoporus air-tightness water of the application examines a preferred embodiment of frock, and the frock is main
It is made up of tank 1, support 2, the first cylinder 3, supporting plate 4, guide rod 5, the second cylinder 6, pressing plate 7 and fixed plate 9.Wherein：
Tank 1 is used to deposit the water of detection, its open topped.
Its top that is fixed on the tank 1 of support 2.
First cylinder 3 is fixed on support 2 vertically, and the cylinder axis of first cylinder 3 stretch out straight down.
Supporting plate 4 is horizontally fixed on the cylinder axis bottom of the first cylinder 3 by screw.
Guide rod 5 sets four altogether, and this four guide rods 5 are fixed on the bottom of supporting plate 4, and this four guide rods vertically
5 rectangular distributions.
Second cylinder 6 is fixed in supporting plate 4 vertically, and the cylinder axis of second cylinder 6 stretch out straight down.
Pressing plate 7 is horizontally disposed, and it passes through sliding sleeve 11 can vertically slidablely be set on guide rod 5 that (sliding sleeve 11 is fixed on pressing plate 7
It is interior, and be slidably matched with guide rod 5), and pressing plate 7 is connected that (the present embodiment is specially the company of being hinged with the cylinder axis of the second cylinder 6
Connect).The lead that the lower surface of the pressing plate 7 offers upward depression puts detent, and is provided with detent on lead set
Upper rubber blanket 8.
Fixed plate 9 is horizontally fixed on the bottom of above-mentioned guide rod 5, and the fixed plate 9 is located at the lower section of pressing plate 7.This is consolidated
The upper surface of fixed board 9 offer to lower recess and positioned at lead put the lead lower detent of set immediately below detent, and
Lower rubber blanket 10 is provided with the lower detent of lead set.
Refer again to shown in Fig. 1, now enter this lead set endoporus air-tightness water inspection frock of the present embodiment to battery lead set endoporus
The method of row sealing propertytest is simply described below：
A certain amount of water is poured into tank 1 first, the lower positioning of lead set lead set A being vertically placed in fixed plate 9 is recessed
In groove.The air pressure of 0.6MPa is passed through to the second cylinder 6, so that the cylinder axis of the second cylinder 6 extend downwards, and then by pressing plate 7
The top that lead covers A is closely pressed on, lead set A is vertically pressed between upper rubber blanket 8 and lower rubber blanket 10, so realizes lead
The sealing of set A upper and lower end faces.Afterwards, the air pressure of 0.6MPa is passed through to the first cylinder 3, so that the cylinder axial direction of the first cylinder 3
Lower elongation, and then cause that supporting plate 4 moves downward away from support 2.The all parts that supporting plate 4 connects below (are mainly pressed
Plate 7, lead covers the part of A and fixed plate 9) together into the water of tank 1, whether there is bubble to emerge to sentence by observing in water
Disconnected lead jacket wall whether gas leakage.
In order that can once detect multiple lead set A, to improve detection efficiency, best above-mentioned lead put detent and
It is as far as possible many that the quantity of the lower detent of lead set is set.In view of lead set A is generally circular configuration, and it is fixed that the present embodiment puts lead
Position groove and the lower detent of lead set are disposed as circular groove, and circular groove is also convenient for processing.
Above-mentioned guide rod 5 uses round bar structure, occurs the possibility that card is related to when sliding up and down to reduce sliding sleeve 11.
The quantity of above-mentioned guide rod 5 is not limited to four, it would however also be possible to employ three, five, and setting can only set one
Or two.It is optimal with three or four to take into account cost and being oriented to stability.
Above content is to combine the further description that specific embodiment is made to the application, it is impossible to assert this Shen
Specific implementation please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of conceiving from the application, some simple deduction or replace can also be made.
