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
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.
