Abstract

The utility model discloses a battery case bulge test frock through fixing the aluminum hull on the mold core, slowly ventilates the back, and the aluminum hull inflation through the interact of bulging force and splint, the aluminum hull can't break away from the mold core. The protective cover prevents the aluminum shell from separating from the mold core when the operation of personnel is improper, and prevents the risk that the aluminum shell is burst and flies out to hurt people; the U-shaped glue has the advantages that the U-shaped glue has elasticity and sealing performance, and not only can protect the shell opening of the battery shell from deformation, but also can prevent air leakage and buffer effect when being clamped. The utility model discloses test fixture is suppressed to the battery case, the simple operation of being convenient for, the security performance is high, and the atmospheric pressure value is convenient for control, and stability is good, and the cost of manufacture is low.

Description

Battery case pressing test tool

Technical Field

The utility model relates to a new forms of energy power battery technical field especially relates to a battery case bulge test frock.

Background

With the rapid development of new energy powered vehicles, the output is larger and larger, and meanwhile, the requirements on the energy density and the safety of a power battery are higher and higher, and especially the safety of a ternary battery is also a technical bottleneck. When the electrolyte in the battery cell is subjected to chemical reaction, gas is generated, when the gas pressure reaches a certain value, explosion danger may occur, and if the bearing capacity of the battery case is insufficient, rupture may occur. Therefore, the risk can be predicted in advance and the explosion-proof valve of the battery cover plate can be guided to be opened for the battery case bearing capacity test.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is exactly in order to compensate prior art's defect, provides a battery case bulge test frock.

The utility model discloses a realize through following technical scheme:

a battery case crush test tool comprises a base, a fixing plate, a U-shaped force rubber plate, a mold core and a clamp plate, wherein an air passage is formed in the side face of the fixing plate, a first air hole communicated with the air passage is formed in the front face of the fixing plate, a second air hole is formed in the U-shaped force rubber plate and the mold core, the first air hole is communicated with the second air hole, the shape and the size of the mold core are the same as those of the inner wall of an opening of a battery case, an opening matched with the battery case is formed in the clamp plate, the fixing plate is fixed on the base, the U-shaped force rubber plate is fixed on the fixing plate, the mold core is fixed on the U-shaped force rubber plate, the opening in the clamp plate is sleeved on the outer side of the mold core, the battery case penetrates through the opening in.

The protective cover covers the outer sides of the fixing plate, the U-shaped rubber plate, the mold core, the clamping plate and the battery shell, and the bottom end of the protective cover is fixedly connected with the base.

And one surface of the mold core is chamfered to be R4 at the periphery, the size of the length and width specification of the aluminum shell is cut by a straight middle line of the clamping plate, a single side of the aluminum shell is provided with a 0.1mm gap, the periphery of the mold core is chamfered to be R3, and the other surface of the mold core cannot be chamfered.

The air flue that the fixed plate side was opened can connect the barometer, conveniently controls atmospheric pressure size. Air enters the aluminum shell from the air passage through the fixing plate and the U-shaped glue from the air holes of the mold core.

The utility model has the advantages that: the aluminum shell is fixed on the mold core, after slow ventilation, the aluminum shell expands, and the aluminum shell can not be separated from the mold core through the interaction of the expansion force and the clamping plate; the protective cover prevents the aluminum shell from separating from the mold core when the operation of personnel is improper, and prevents the risk that the aluminum shell is burst and flies out to hurt people; the U-force glue has the advantages that the U-force glue has elasticity and tightness, and can not only protect the shell opening of the battery shell from deformation, but also prevent air leakage and buffer action when being clamped; the utility model discloses test fixture is suppressed to the battery case, the simple operation of being convenient for, the security performance is high, and the atmospheric pressure value is convenient for control, and stability is good, and the cost of manufacture is low.
