[0015] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0016] As shown in the figure, a lithium battery axis spot welding combined positioning die, including the mould body 1 of cylindrical structure, the mould body 1 is the phenolic resin material, make its whole has better insulation, antistatic, wear resistance and high temperature resistance, facilitate the spot welding of battery.

[0017] The mould body 1 is provided with the axis warehouse 2 that passes through, and the axis warehouse 2 is coaxial with the mould body 1, that is, the axis warehouse 2 is the passage that passes through the center of the mould body 1, can be used for fixing spot welding axis, to ensure the accurate positioning of spot welding axis, improve the precision and consistency of spot welding process, and simultaneously, it is coaxial with the mould body 1, avoids the spot welding error caused by axis deviation, provides stable axis support for the spot welding process, and ensures the spot welding quality.

[0018] The one end of mould body 1 is equipped with a plurality of different inner diameter sizes and the battery position 3 of stepped shape, and the plurality of battery positions 3 are coaxially arranged and coaxial with the axis warehouse 2, and the lithium battery can be placed in one of the battery positions 3, which is used for adapting to the installation and positioning of different models of batteries, realizes the characteristics of one for multiple uses, can reduce the frequency of die replacement, and since it is coaxial with the axis warehouse 2, the centring of the battery and the axis can be ensured, and the spot welding precision is improved.

[0019] One side of the mould body 1 is provided with a slot 4, and the slot 4 is connected with the outside space of the mould body 1, and the purpose is to solve the problem of difficult battery leading-in and leading-out caused by limited space, to improve the convenience of operation, reduce the operation difficulty and time cost.

[0020] This lithium battery axis spot welding assembly positioning mold, when in use, places the battery in the battery compartment 3 at one end of the mold body 1 according to the lithium battery model and size. The spot welding axis can be inserted into the axis compartment 2, allowing spot welding to be performed while the battery is positioned. After spot welding, the spot welding axis can be led out from the slot 4. Because the mold body 1 is made of phenolic resin, it can protect the battery. The entire spot welding process achieves high precision, high efficiency, and high reliability in lithium battery spot welding, and is suitable for various lithium battery production scenarios of different sizes.
