As preferably, the bottom surface of described butt platform is than the high 1～5mm in the bottom surface of bar shaped body.
A kind of accumulator pole group welding tooling comprises:
Be resisted against the described press strip of a side of lug among the utmost point group;
A side relative with press strip has the comb mould of the broach that closes with utmost point flock mating.
For avoiding the scratch pole plate, the top of described broach has chamfering.
Preferably, described accumulator pole group welding tooling also comprises the support for fixing comb mould.
Support makes utmost point group more firm, is conducive to welding.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has increased the bonding strength of bus-bar and lug by press strip is improved, and the electric conductivity of battery is better, and presentation quality is also more excellent simultaneously.
The utility model is reequiped on the prior art basis, has kept prototype structure to greatest extent, can only replace press strip and get final product, and it is simple to be used for the processing technology of press strip of accumulator pole group welding.
