The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Specific embodiment of the utility model one:
As shown in Figure 1, when using the laser beam 11 Precision Machining welding work pieces 13 that send by laser instrument 15 traditionally, the design of the plumb joint of laser-beam welding machine be with traditional valve 12 circulating type ground devices near welding position 10, easy and the welding work pieces 13 generation interference of such valve design, shown in the figure circular portion, thereby can not critically handle the thin portion of workpiece.
As shown in Figure 2, the utility model adopts described tubulose blowing nozzle 21 to connect described air inlet 24; In this example, described plumb joint 14 is connected with described air inlet 24, and described plumb joint 14 flexibly connects by described tracheae pallet 23 with described tubulose blowing nozzle 21; The apparatus for bending that described tubulose blowing nozzle 21 adopts is that rotational angle 90 degree are to 180 degree bending tubes, intermediate seal is hinged, can manually adjust, in conjunction with the flexible connection of described tracheae pallet 23 junctions, can adjust the air blowing height and the relative angle of welding laser axis of described tubulose blowing nozzle 21.The material of tubulose blowing nozzle is for example heat-conducting silicone grease or an organic polymer of the good composite of thermal diffusivity, the perhaps well higher metal of fusing point simultaneously of thermal diffusivity, for example aluminium, aluminium alloy or copper, what adopt is copper pipe herein, so that prevent a large amount of sparks fusing blowing nozzles of sputter in welding process.The air blowing oral area cutting profile of described tubulose blowing nozzle 21 can be according to concrete device to be processed and difference, in order that make the air-blowing mouth press close to the Laser Welding contact better.Described tubulose blowing nozzle 21 is to flexibly connect with described tracheae pallet 23.And the utility model has adopted by described stepper motor 25 by the described synchronous pulley 22 of belt drives, during practical operation, in response to different welding work pieces shapes, described stepper motor 25 is by the described synchronous pulley 22 of described belt drives, and described synchronous pulley 22 drives described tubulose blowing nozzle 21 translation-angles.Described stepper motor 25 is fixedly connected on described plumb joint 14.
