PendingCN114871670AReduced welding tolerancePrevent mutual movementFinal product manufactureWelding/cutting auxillary devicesStructural engineeringBattery pack
The invention relates to a novel square battery pack aluminum-palladium welding jig which comprises a jig body, first fixing clamping seats and second fixing clamping seats, limiting grooves are formed in the periphery of the jig body, and one first fixing clamping seat and three second fixing clamping seats are installed in the four limiting grooves correspondingly. A welding groove for limiting aluminum palladium is formed in the jig main body; the first fixing clamping seat and the second fixing clamping seat can effectively limit relative movement of the battery pack and the jig, the lower surface of the jig is consistent with the positive and negative electrode surfaces of the battery pack, aluminum palladium movement is limited most effectively, the safety performance is high, and the insulating property is good; the material can prevent a welded battery pack from being damaged due to faults of a welding machine, the material is a flame-retardant material, the efficiency is high, the error-tolerant rate is high, and the conditions such as pseudo soldering in the welding process can be effectively prevented.
