Description
Technical field
The utility model is related to welding field, particularly relates to a kind of compressing apparatus for laser beam welding.
Background technology
Current widely used laser welding technology, because of its high efficiency, high automation, great convenience is brought to production.Swash
Photocoagulation is a kind of contactless welding, without pressure during work.However, to form qualified molten bath and weld seam, it is still necessary to be welded
Storeroom tight fit is connect, it is very close to each other.Therefore pressing device need to be designed to be fitted close material to be welded, and can not influenceed
Light path, it is impossible to interference welding.Under this background, the design of various mechanical clamping devices is arisen at the historic moment.It is characterized in by power
Structure design is learned there is provided intensifying force, the demand of different frocks is met.The limitation of mechanical clamping device is that mechanical structure is occupied
Space, complicates device systems.Tackle some fine weldments, complicated weldment, mechanical clamping device may structure it is more multiple
It is miscellaneous or even not competent.The battery modules of such as electric automobile by multiple battery cell electrodes and bus-bar, it is necessary to carry out laser
Welding, not only number of welds is huge, position is fine, complicated, and mechanical clamping device manufacture and design it is also highly difficult, into
This is also high.
Therefore, how a kind of compressing apparatus for laser beam welding is provided, can so that material tight to be welded coordinate, simultaneously tie
Structure is simple, cost is low, a difficult problem as pendulum in face of those skilled in the art.
The content of the invention
Be to provide a kind of compressing apparatus for laser beam welding in the purpose of this utility model, using spraying high-pressure gas device with
The structure that part to be welded coordinates, it is possible to use gases at high pressure compress part to be welded, realize the tight fit of laser welding, while high pressure
Gas generation apparatus is essentially laser welding apparatus necessary devices, therefore without separately put into, it is to avoid manufacture and design machinery pressure
Tight device, reduces cost, so as to efficiently solve foregoing problems.
The utility model is achieved through the following technical solutions：
The utility model provides a kind of compressing apparatus for laser beam welding, includes laser welding apparatus, part to be welded one, to be welded
Part two, also includes spraying high-pressure gas device, and the spraying high-pressure gas device is protective gas injection apparatus, protective gas
Ring-type or multi-port shape protection gas blowout pipe are set on injection apparatus, the distance between gas blowout pipe and part to be welded one are protected in adjustment, until
When protecting gas blowout pipe sustained firing protection gas, static pressure area is constituted between protection gas nozzle exit and part to be welded, except to part to be welded one
Outside the enough and constant pressure of holding, overflow gas and welding position is played a protective role.
Preferably, the part to be welded one is provided with flexible structure, the compression to position to be welded plays the effect of benefiting.
It should be appreciated that foregoing description substantially and follow-up description in detail are exemplary illustration and explanation, should not
As the limitation to the claimed content of the utility model.
The beneficial effects of the utility model are：
1st, a kind of compressing apparatus for laser beam welding of the utility model, the knot coordinated using spraying high-pressure gas device and part to be welded
Structure, the distance between adjustment spraying high-pressure gas device gas injection outlet and part to be welded, by gases at high pressure sustained firing to be welded
Part produces constant pressure, so as to constitute static pressure area, part to be welded is compressed, the tight fit of laser welding is realized.
2nd, the spraying high-pressure gas device that the utility model is used is essentially laser welding apparatus necessary devices, therefore nothing
It need to separately put into, it is to avoid manufacture and design mechanical clamping device, reduce cost.
3rd, the utility model makes part to be welded have certain shrinkage using flexible structure is set on part to be welded one, contributes to welding
Compress.

Embodiment
By reference to one exemplary embodiment, the purpose of this utility model and function and for realizing these purposes and function
Method will be illustrated.However, the utility model is not limited to one exemplary embodiment as disclosed below；Can be by not
It is realized with form.The essence of specification is only to aid in various equivalent modifications Integrated Understanding the utility model
Detail.
Here, it should also be noted that, in order to avoid having obscured the utility model because of unnecessary details, in the accompanying drawings
It illustrate only and according to the scheme of utility model closely related structure and/or process step, and eliminate new with this practicality
The little other details of type relation.
Hereinafter, embodiment of the present utility model will be described with reference to the drawings.In the accompanying drawings, identical reference is represented
Same or similar part, or same or like step.
A kind of compressing apparatus for laser beam welding of the utility model shown in reference picture 1, includes laser welding apparatus 1, to be welded
Part 1, part to be welded 22, also include spraying high-pressure gas device 4, and spraying high-pressure gas device 4 is that protective gas sprays dress
Put, ring protection gas blowout pipe is set on protective gas injection apparatus 4；Static pressure area is constituted between ring protection gas blowout pipe and part to be welded 1
6；Part to be welded 1 is provided with flexible structure 5.
During laser welding, protective gas injection apparatus goes out protective gas by ring protection gas blowout pipe sustained firing, is going out
Oral area position forms the constant static pressure area 6 of pressure, by protecting gas static pressure to compress welding position, along with setting soft on part to be welded 1
Property structure 5, the compression of part to be welded can be better achieved, while the protective gas that nozzle hole is escaped towards welding position can be used for welding
The protection connect.
Protective gas injection apparatus set by laser equipment is generally only used for protecting welding position, and the utility model leads to
The distance crossed between adjustment gas injection outlet and part to be welded, until protective gas sustained firing part to be welded is produced enough pressure and
Pressure is constant, that is, constitutes static pressure area, compresses welding position by static pressure, realizes the tight fit of laser welding.
