Specific implementation mode
As depicted in figs. 1 and 2, a kind of lithium battery pressure-bearing tests gas explosion tooling, including pedestal, base cover and side seals
Block；In a rectangular parallelepiped shape, 1 upper surface of the pedestal is connected the pedestal 1 by location hole 1-2 and the locking of base cover 3, the pedestal
The experiment opening that bearing groove 1-1, the bearing groove 1-1 have been drawn in 1 upper surface is unfolded towards right side, paving inside the bearing groove 1-1
It is filled with injecting hole cushion rubber 2-1 between compressed air injecting hole 5-3 on the inside of electric discharge pond 2, the battery 2 and side seals block 5,
The side seals block 5 is tightly connected by rubber pad 5-1 and battery safety valve 2-2, the side seals block 5 by screw with
Pedestal 1 is tightly connected.Wherein, tool assembly is produced for convenience, and the tooling shape of the utility model is in a rectangular parallelepiped shape.Pass through length
The structure of cube shape quickly and effectively can be modeled and be put into production, and substantially increase production efficiency.In order to effectively will be prior
Ready battery 2 is put into tooling, and bearing groove 1-1 has been drawn in 1 upper surface of the pedestal.The experiment of the bearing groove 1-1 is opened
Mouth is unfolded towards right side, can quickly be laterally inserted into battery 2 in this way, time saving and energy saving.In order to which battery 2 is sealed,
Side seals block 5 and base cover 3 are mounted at the exposure of bearing groove 1-1.Having been opened up on side seals block 5 simultaneously can be square
Just the injecting hole 5-3 of injecting compressed air.Finally in order to ensure that compressed air is not revealed, in the compressed air injecting hole
5-3 is corresponding with the injecting hole cushion rubber 2-1 in 2 outside of battery.In order to enhance ductility of the battery safety valve 2-3 in tooling,
The battery safety valve 2-3 and rubber pad 5-1 is sealed filling.Since the battery safety valve 2-3 wind pressure born is about
3Mpa, but the gas injection pressure detected is about 6Mp.So it is easy to appear air leakage phenomenas by battery safety valve 2-3.So being
The generation for preventing this phenomenon, by rubber pad 5-1 does soft contact with battery safety valve 2-3.Anti- battery safety valve 2-3 receives note
When atmospheric pressure is to external deformation, deformation complementation can be done by rubber pad 5-1.It can prevent battery safety valve 2-3 from occurring in this way
Air leakage phenomena.
As depicted in figs. 1 and 2, the pedestal 1 is respectively provided with longitudinal screw hole 6-1 and lateral screw hole at top and left part
Be mounted with screw rod 8 in 7-1, the longitudinal direction screw hole 6-1 and lateral screw hole 7-1 respectively, two screw rods 8 pass through longitudinal direction screw hole 6-1 with
Lateral screw hole 7-1 is fitting to connection with longitudinal pushing block 6 and lateral pushing block 7 respectively, and 8 end of the screw rod is equipped with butterfly bolt 9.Wherein,
In order to allow the tooling to can adapt to the battery 2 to be detected of different sizes, at the top of the pedestal 1 and left part equipped with vertical
To pushing block 6 and lateral pushing block 7.Staff hole passes through longitudinal direction screw hole 6-1 and transverse direction screw hole 7-1 respectively to longitudinal direction by screw rod 8
Pushing block 6 and lateral pushing block 7 carry out the adjusting of size.Finally mesuring battary 2 is effectively limited, is oozed in order to avoid there is compressed air
Leakage.
As shown in Figure 1, the longitudinal direction pushing block 6 and 7 ejection face of lateral pushing block are contacted with the side horizontal of battery 2 respectively.Its
In, since longitudinal pushing block 6 and lateral pushing block 7 are to battery 2 squeeze by horizontal plane pushing away limit.Become from usual electrical contact
It is changed to face contact, limit efficiency can be greatly improved, prevents battery run-off the straight occur squeezing the during of pushing away limit, to nothing
The case where method face compressed air mouth, occurs.
As shown in Figure 1,5 medial surface of side seals block is drawn, there are two limiting slot 5-2, the limiting slot 5-2 and electricity
The protrusion in pond 2 is corresponding, and the limiting slot 5-2 is filled with rubber pad 5-1.Wherein, for the lug boss of 2 output end of match battery
Point, it is drawn there are two limiting slot 5-2 in 5 medial surface of side seals block.It is also completed in such a way that filled rubber pads 5-1 simultaneously
Processing in sealing contact.It can effectively prevent in this way and occur leaking out in seal process and jitter phenomenon.
As shown in Figure 3 and Figure 4,3 top of the base cover is fixedly connected with handle 4, and 3 bottom of the base cover is fixedly connected
There are two boss 3-1, and the through-hole of the boss 3-1 transverse directions is corresponding with the through-hole at 1 bottom end chimb of pedestal, the boss 3-1
It is connected by screw and the locking of 3 bottom flange of base cover.Wherein, base cover 3 is opened in order to facilitate technical staff.In the pedestal
3 top of lid is fixedly connected with handle 4.And it is fixedly connected there are two boss 3-1 in 3 bottom of the base cover, recycles boss
3-1 is connected by screw and the locking of base cover 3.The stability that base cover 3 is connect with tooling can be enhanced in this way.
To sum up, the utility model substantially increases the sealing performance of tooling by the way of elastic extruding type sealing.It is original
Fashion of extrusion be point contact, and the utility model uses the mode of face contact to substantially increase battery tight inside tooling
Close type, and then avoid and compress the gas leak phenomenon that injecting hole deviation is brought when battery does pressure-bearing test.The filling of rubber pad is more
Effectively raise the matching degree of battery and tooling.
Although the foregoing describe specific embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely examples, various changes or modifications can be made to present embodiment, without departing from the original of the utility model
Reason and essence, the scope of protection of the utility model are only limited by the claims that follow.
