Background technology
At present be rigid the connection mostly between the laser weld nozzle that uses gas shield device and the cooling device, for the laser weld of complex component, the gas shield weak effect; Oxidation is serious, has reduced the mechanical property of weldment on largely, especially for the laser weld of easy oxidation metal; Gas shield device mostly adopts and drags cover; Because the existence of dragging cover, some complicated spatial structure can't realize gas shield at all, have dwindled the range of application of laser weld processing greatly.In addition, the end face of nozzle adopts circular section perpendicular to axial direction basically, and the disperse scope of weld seam top protective gas is little, is unfavorable for the protection of weld seam, is prone to cause oxidation.
The utility model content
The utility model technical problem to be solved is: provide a kind of laser weld to use gas shield device, it is flexible poor to solve the laser weld gas shield device, and range of application is little and protect weak effect, weld seam to be prone to the problem of oxidation.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
A kind of laser weld is used gas shield device; It comprises water inlet pipe 1, seat 2, air inlet pipe 3, gas transitional crust 4, installing plate 5, clip 6, nozzle 8, tube connector 9, adjustable plastic cooling hose 10, cooling cylinder 11, outlet pipe 12, breather pipe 13, and installing plate 5 one sides are connected with clip 6, and opposite side is connected fixing with cooling cylinder 11 usefulness bolts; Two seat 2 upper ends are inserted water inlet pipe 1 and outlet pipe 12 respectively; Air inlet pipe 3 is directly inserted in the air admission hole of gas transitional crust 4 tops, and breather pipe 13 passes from cooling cylinder 11, and an end inserts gas transitional crust 4 and is attached thereto; The other end is connected with adjustable plastic cooling hose 10; The other end of adjustable plastic cooling hose 10 is connected with tube connector 9, and tube connector 9 adopts with nozzle 8 and is threaded, and makes nozzle 8 be in the top of weld seam.
Described laser weld is fixed in the laser head outside with gas shield device is whole with clip 6, and clip 6 connects two clips 6 fixing according to laser head size adjustment spacing with bolt.
The outlet side of described nozzle 8 is inclined-plane ellipticity, and this end face is parallel with the weld parts facet during welding, and the end face of giving vent to anger of this shape makes the protective gas dispersion surface of ejection wider, and the disperse of maximum magnitude ground is guaranteed the best protection effect in the weld seam top.
Described water inlet pipe 1 makes cooling water turnover circulation in cooling cylinder 11 with outlet pipe 12, and the protective gas in the cooling breather pipe 13 has guaranteed output gas barrier weld seam top air, guarantees the commissure in the atmosphere of protective gas, and the cooling weld seam reduces oxidation.
The beneficial effect of the utility model is: 1, easy accessibility, and simple in structure, long service life, flexible operation is protected effective.2, between nozzle and the cooling cylinder for flexibly connecting, nozzle and workpiece collide to nozzle even whole gas shield device and bring damage when avoiding rigid connection.3, after welding finishes can with adjustable plastic cooling hose together with nozzle on laser head, avoid damaging.
