Fig. 2 is a kind of structural schematic diagram of laser galvanometer scanning welder of another preferred embodiment of the utility model.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the utility model provides a kind of coaxial blowning installation of laser galvanometer scanning welding, special
Sign is that the coaxial blowning installation includes：
Transparent medium plate 100；
Air duct board 200 on the transparent medium plate 100 is set；
The air duct board 200 is equipped with several perforative through-holes 300 up and down；And
At least one admission line 400 being connected with each through-hole 300.
Preferably, the admission line 400 is equipped with the solenoid valve opened or be closed for admission line 400 (in figure
It does not mark).
Preferably, 300 internal diameter of the through-hole is up big and down small.
Preferably, it is tightly connected between the transparent medium plate 100 and air duct board 200.
Specifically, can be sealed by glue or other media between transparent medium plate 100 and air duct board 200 solid
It is fixed, when lasing light emitter is mapped on transparent medium plate 100, transparent medium plate 100 is passed through, meanwhile, pass through the through-hole on air duct board 200
300 are mapped on weld seam and are welded.
Protective gas is passed through in admission line 400 simultaneously, protective gas enters from 300 side wall of through-hole in through-hole 300,
Since 300 upper end of through-hole and the sealing of transparent medium plate 100 are fixed, protective gas can only be projected from 300 lower face of through-hole, at this point,
Lasing light emitter is also projected from 300 lower face of through-hole, realizes lasing light emitter and protective gas is coaxially concentric projects, dispelled laser focusing
The volume of smoke and plasma in direction, to improve welding quality, the welding efficiency of workpiece.
What needs to be explained here is that protective gas can be divided into two classes：Inert gas and active gases.What inert gas referred to
It is helium and argon gas, never reacts with melting weld seam, (metal-noble gas arc welding) is welded for MIG.Activity
Gas generally comprises carbon dioxide, oxygen, nitrogen and hydrogen.These gases are by stablizing electric arc and ensuring that material smoothly passes
Weld seam is sent to participate in welding process, when accounting for most of, weld seam can be destroyed, but it is special to improve welding instead on a small quantity
Point welds (metal-active gases arc welding) for MAG.
In design, a plurality of admission line 400 can be designed on 300 side wall of through-hole, every admission line 400 connects
A kind of protective gas source realizes through-hole 300 by corresponding channel and blows.
For example, air duct board 200 is equipped with first through hole 300, the second through-hole 300 and third through-hole 300, each through-hole 300
Three admission lines 400 are designed on side wall, every admission line 400 is equipped with solenoid valve (not marked in figure), passes through controller
Control, when needing to be blown by helium in first through hole 300, at this point, 300 side wall of the second through-hole 300 and third through-hole
On admission line 400 closed by solenoid valve (not marked in figure), three admission lines 400 on 300 side wall of first through hole
An admission line 400 into helium is only opened by solenoid valve (not marked in figure), is blown to first through hole 300.When
When needing other protective gas, other solenoid valve (not marked in figure) is opened, it, can be with root when needing hybrid protection gas
It is mixed according to needing to open multiple solenoid valves (not marking in figure).
Preferably, the coaxial blowning installation further includes：
The mounting bracket 500 being connected with the air duct board 200 and/or transparent medium plate 100；And
It is connected with the mounting bracket 500, the multiaxis mobile platform 600 for controlling the movement of the mounting bracket 500.
Specifically, because of the difference according to position while welding, if in each welding, it is required for blowning installation is again solid
Dingan County fills, fairly cumbersome, in order to solve this problem, a multiaxis mobile platform 600 is designed on blowning installation, passes through multiaxis
Mobile platform 600 realizes the position movement of XYZ axis, is convenient for the movement of blowning installation.
