The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of pressing of cylindrical battery laser welding, which is blown, to be controlled
Tool comprising lifting cylinder is driven the support plate to move up and down by the lifting cylinder and is fixed on the support plate
On fixed plate, be provided with several cylindrical holes corresponding with battery battery core position in the fixed plate, be arranged in the cylindrical hole
There is the internal layer gas spacer across the support plate, form annular air channel between the internal layer gas spacer and the cylindrical hole,
The fixed plate internal symmetry is provided with the gas flow being connected to the annular air channel, and being provided in the support plate can be upper and lower
Elastic pressure mouth that is floating and being set in the internal layer gas spacer outer surface, the elasticity pressure mouth and the internal layer gas spacer
Between there are gap, the gap is connected to the annular air channel.
Further, the fixed plate two sides are provided with the ventilation nozzle being connected to the gas flow.
Further, the elastic pressure mouth outer surface is arranged with the setting of elastic component and sunk type in the support plate.
Further, the elastic pressure mouth passes through the support plate and extends downward into battery battery core anode welding position, and
Compress cylinder manifold welding position.
Compared with prior art, a kind of beneficial effect of cylindrical battery laser welding pressing air blow jig of the utility model exists
In: at the same play a dual role of protective gas blow and welding position press, effectively ensured battery battery core anode with
Weld strength between eight pawl elastic slice of cylinder manifold guarantees that welding pulling force is reliable, while guaranteeing that solder joint beauty is met the requirements, and meet
Test chemical requirement.

[specific embodiment]
Embodiment:
Fig. 1-Fig. 2 is please referred to, the present embodiment is that cylindrical battery laser welding presses air blow jig 100, is used for cylinder electricity
Welding between pond battery core anode and eight pawl elastic slice of cylinder manifold, including lifting cylinder 1, by the driving of lifting cylinder 1 carried out fortune up and down
Dynamic support plate 2 and the fixed plate 3 being fixed in support plate 2 are provided in fixed plate 3 several corresponding with battery battery core position
Cylindrical hole, be provided through the internal layer gas spacer 4 of the support plate 2 in the cylindrical hole, internal layer gas spacer 4 with it is described
Annular air channel 5 is formed between cylindrical hole, 3 internal symmetry of fixed plate is provided with the gas flow 6 being connected to annular air channel 5, fixed
3 two sides of plate are provided with the ventilation nozzle 7 being connected to gas flow 6, are provided with can floating up and down in support plate 2 and are set in internal layer
The elastic pressure mouth 8 of 4 lower external face of gas spacer, there are gaps (not to mark in figure between elastic pressure mouth 8 and internal layer gas spacer 4
Know), the gap is connected to annular air channel 5.
Elastic 8 outer surface of pressure mouth is arranged with the setting of elastic component 9 and sunk type in support plate 2, and elastic pressure mouth 8 passes through branch
Fagging 2 extends downward into battery battery core anode welding position, and compresses cylinder manifold welding position.
The present embodiment cylindrical battery laser welding press air blow jig 100 for a kind of cylindrical battery cell cathode housing and
Laser welding between eight pawl elastic slice plastic processing frames, cooperation laser-beam welding machine carry out using.Its working principle is that: when cylindrical battery is put
After setting in place, lifting cylinder 1 drives jig entire lowering, and elastic pressure mouth 8 compresses welding position；The light beam of laser passes through described
Cylindrical hole, internal layer gas spacer 4 and elastic pressure mouth 8 reach welding position；Protective gas enters gas flow 6 from ventilation nozzle 7,
Welding position is reached through the gap between annular air channel 5, elastic pressure mouth 8 and internal layer gas spacer 4 again, molten bath is blown
