The utility model content
The utility model technical problem to be solved is to provide a kind of jig detent mechanism that is used for laser welding lug leader and pole.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of jig detent mechanism that is used for laser welding lug leader and pole; Mainly form by jig inner chamber, fluting pressing plate and elastic force clamp; Said jig inner chamber is provided with the groove that is used to locate battery cover foremost, and the groove rear is fixed with two boss that are used to support leader and battery electrode column, and said jig inner chamber both sides also are fixed with locating piece; The elastic force clamp is fixed on the said locating piece; The fluting pressing plate is positioned at jig inner chamber top, fixes through elastic force clamp and jig inner chamber, and the front end of said fluting pressing plate is provided with the laser weld groove.
Preferably, the above-mentioned jig detent mechanism that is used for laser welding lug leader and pole, said locating piece is positioned on the same horizontal line parallel with groove with boss.
Preferably, the above-mentioned jig detent mechanism that is used for laser welding lug leader and pole, the quantity of said boss is identical with the quantity of laser weld groove.
Preferably, the above-mentioned jig detent mechanism that is used for laser welding lug leader and pole, said boss quantity is two.
Preferably, the above-mentioned jig detent mechanism that is used for laser welding lug leader and pole, said laser weld groove quantity is two.
The utility model structure has following beneficial effect:
The above-mentioned jig detent mechanism that is used for laser welding lug leader and pole, reasonable in design uses the fluting pressing plate to compress lug leader and pole, guarantees between the lug leader and the lug leader cooperates with no gap between the pole; Manpower has been saved in the design of elastic force clamp, and operability is stronger, and whole jig detent mechanism takes up room little, simple to operation.
