Utility model content
The purpose of this utility model is that providing a kind of rectangular lithium ion battery suppresses test device, this to suppress test dress
Put easily operated, convenient and swift when to battery suppress test, and production efficiency can be improved.
To achieve the above object, the utility model employs following technical scheme：
A kind of rectangular lithium ion battery suppresses test device, including the outer fixture for clamping square battery and interior fixture,
And the aerating device of gas injection is carried out for square shaped battery, the compressed gas that the aerating device includes being arranged on contiguous block connects
Mouthful, the bottom of the contiguous block is hinged on base, top be hinged on bending shape control stick end, pass through manipulation bar
Contiguous block is set to be moved up and down with compressed gas interface.
Further scheme, the outer fixture are fixed on workbench, and connecting rod, the connection are connected with the outside of interior fixture
Bar is located in cutting ferrule, make connecting rod in cutting ferrule move forward and backward and drive in fixture along movable workbench, realize square shaped
The clamping or release of battery.
Further scheme, the cutting ferrule are fixed on the table by pedestal.
Further scheme, the middle part of the control stick are hinged by connection sheet and base.
Further scheme, the diameter of the compressed gas interface are more than the diameter of the liquid injection hole of rectangular cell, it can be ensured that compression
Air-tightness when gas interface is directed at battery liquid-filling hole and is filled with compressed air thereto therebetween.
Battery to be tested is first positioned over the middle of interior fixture and outer fixture, and make its note by the present apparatus in operation
Fluid apertures is located at the lower section of compressed gas interface, connecting rod is moved along cutting ferrule to the direction close to battery, fixture moves in promotion
And clamp battery together with outer fixture；Control stick is pushed, because control stick is bending shape structure, when one end pushes, the other end
It can then rise；And the end of control stick is to be hinged by contiguous block with base, when manipulation boom end moves upwards, then cut with scissors
The contiguous block connect can then be moved downward with compressed gas interface and is aligned with the liquid injection hole of battery.Then it is filled with pressure to inside battery
Contracting air measures battery anti-explosion valve and weld seam until explosion-proof valve or battery weld seam explosion by the pressure gauge of external compressed air
Burst pressure force value.When explosion-proof valve or weld seam explosion, the registration of pressure gauge is the burst pressure of explosion-proof valve or weld seam.Suppress survey
Try after terminating, then connecting rod and interior fixture are moved to the direction away from battery, then control stick is lifted so as to drive compressed gas
Interface is lifted up, and most rectangular cell is totally released at last.
The utility model ensures battery to be tested being clamped positioning by the movement of interior fixture, then controls compressed gas
The lifting of interface, compressed gas interface is aligned with the liquid injection hole of battery and be filled with compressed air to inside battery, pass through external pressure
The pressure gauge of contracting air measures the burst pressure force value of battery anti-explosion valve and weld seam.
So of the present utility model suppress test device, to battery suppress easily operated, convenient and swift during test, energy
Enough improve production efficiency.
