Description
Technical field
The utility model belongs to laser welding apparatus field, especially a kind of cooling device of laser welding.
Background technology
Laser welding is a kind of novel welding manner, and mainly for the welding of thin-walled material, precision component, weld seam is flat
Whole, beautiful, weldquality is high, and pore-free accurately controls, and focal spot is small, and positioning accuracy is high, easily realizes automation, therefore
Laser-beam welding machine is obtained for very extensive application in many fields.
Traditional laser welding always exists insoluble problem, that is, after welding a period of time, welding quality becomes
It is bad, it can cause welding job that can not carry out when serious, main cause has at 3 points：First, having in the welding process in laser channeling
Dust enters, and pollutes eyeglass, and reflectivity reduces, and influences laser efficiency of transmission；Second is that laser channeling does not have gas exchanges with extraneous,
Light beam transmits in closed light path, and temperature can be gradually increasing, and light path pattern is caused to change, to influence to weld；Third,
The workpiece not cleaned up, face of weld will appear stomata, influence welding quality.
Utility model content
In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of coolings of laser welding
Device.Cavity forms one of air curtain as annular air channel around laser welding nozzle, and dust is avoided to enter laser beam passway, dirty
Eyeglass is contaminated, while the workpiece of welding can be purged, prevents workpiece from not cleaning up and the problem of weld porosity occurs, is coordinated
Coil pipe cools down, and prevents laser beam temperature rise in laser channeling transmission process, zlasing mode is caused to change, and influences to weld matter
Amount.
In order to achieve the above objectives, it is as follows to provide technical solution：
A kind of cooling device of laser welding, which is characterized in that including thang-kng pipe, cavity, water inlet pipe, outlet pipe, air inlet
Pipe, the thang-kng pipe are made of thang-kng tube shell；There is coil pipe outside the thang-kng tube shell；The coil pipe be semicanal and lower part with
Water inlet pipe connection, top and outlet pipe connect；The cavity is formed as annular air channel by cavity outer wall and cavity inner wall；Institute
The top for stating cavity outer wall is connected with air inlet pipe；The cavity is closely connect with coil pipe, and the cavity lower part is equipped with separation net.
Preferably, the gas in the air inlet pipe is helium.
Preferably, the separation net is stainless steel, mesh diameter 3mm-5mm.
Preferably, the mesh diameter of the separation net is 4mm.
Compared with the existing technology, have the advantage that is the utility model with effect：
The cooling device of laser welding utilizes cavity one of formation around laser welding nozzle is axial as annular air channel
Air curtain makes extraneous dust cannot be introduced into laser beam passway, pollution eyeglass, while can be purged to the workpiece of welding, prevents
Only workpiece, which does not clean up, there is the problem of weld porosity, on the other hand, coordinate on thang-kng tube shell inside the coil pipe that coils by
Under cooling to the cooling water being above passed through to thang-kng pipe, prevent laser beam temperature rise in laser channeling transmission process, cause
Zlasing mode changes, and influences welding quality.

Specific implementation mode
As shown in Figures 1 to 4, a kind of cooling device of laser welding, including thang-kng pipe 10, cavity 2, water inlet pipe 3, water outlet
Pipe 4, air inlet pipe 5, thang-kng pipe 10 are made of thang-kng tube shell 1；There is coil pipe 11 outside thang-kng tube shell 1；Coil pipe 11 be semicanal and
Lower part is connect with water inlet pipe 3, top and outlet pipe 4 connect；Cavity 2 is used as annular air channel, by cavity outer wall 21 and cavity inner wall
22 form；The top of cavity outer wall 21 is connected with air inlet pipe 5；Cavity 2 is closely connect with coil pipe 11, and cavity lower part is equipped with separation net
20。
According to above-mentioned construction, laser welder work carry out when, the cooling device of laser welding and laser generator 30 and
Laser welding nozzle 40 be connected, the gas entered in air inlet pipe 5 using cavity 2 as annular air channel in 40 axis of laser welding nozzle
One of air curtain is formed to surrounding, so that extraneous dust is cannot be introduced into laser beam passway, pollution eyeglass, while can be to the work of welding
Part is purged, and prevents workpiece from not cleaning up and the problem of weld porosity occurs, on the other hand, disk on cooperation thang-kng tube shell 1
Around cooling of the cooling water that is passed through from down to up of the inside of coil pipe 11 to thang-kng pipe 10, prevent laser beam to be transmitted across in laser channeling
Temperature rise in journey, causes zlasing mode to change, and influences welding quality.
Wherein, the gas in air inlet pipe 5 is helium, and helium energy density is high, can be carried out to laser welding further
Protection so that laser welding realizes single-side welding double-side forming.
Wherein, separation net 20 be stainless steel, under normal circumstances mesh diameter be 3mm-5mm, in the present embodiment every
The mesh diameter of off-network 20 is 4mm.It can so that air curtain is more uniform with the cooperation of cavity 2, and can effectively prevent extraneous miscellaneous
Object enters inside cavity 2.
The utility model is not limited to the above embodiment, and embodiment is only exemplary, it is intended to for explaining that this practicality is new
Type, and should not be understood as limiting the present invention.
