A sliding groove which is perpendicular to the guide rail is arranged on the other side, opposite to the guide rail, of the Y-axis sliding plate 202, the guide rail and the sliding groove in the Y-axis sliding plate are perpendicular to each other, a Z-axis screw rod mounting plate 208 and a Z-axis limiting plate 209 are respectively arranged on two sides of the sliding groove of the Y-axis sliding plate 202, a protruding guide rail is arranged on one side of the Z-axis sliding plate 206 and is in fit connection with the sliding groove of the Y-axis sliding plate 202, a threaded hole is formed in the guide rail 2061 of the Z-axis sliding plate 206, and the Z-axis screw rod 207 penetrates through the threaded hole; the Z-axis limiting plate 209 can limit the Z-axis sliding plate 206 to slide out of the Z-axis limiting plate 209, the Z-axis sliding plate 206 can slide in the chute of the Y-axis sliding plate 202 through a guide rail, and the sliding distance of the Z-axis sliding plate 206 in the chute of the Y-axis sliding plate 202 can be controlled through the Z-axis screw 207. For example, in some specific ways, threaded holes are formed in two sides of the sliding chute of the Y-axis sliding plate 202, and the Z-axis screw mounting plate 208 and the Z-axis limiting plate 209 are fixed by the threaded holes and screws on two sides of the sliding chute of the Y-axis sliding plate 202.

X axle bottom plate 210 is equipped with the spout with Z axle slide 206 fixed connection and X axle bottom plate 210's one side, X axle bottom plate 210's spout both sides are equipped with X axle screw mounting panel 213 and X axle limiting plate 214 respectively, X axle slide 211's one side is equipped with bellied guide rail and is connected with X axle bottom plate 210's spout cooperation, X axle slide 211's guide rail is equipped with the screw hole, X axle screw 212 passes screw hole and X axle screw mounting panel 213 of X axle slide 211's guide rail, X axle slide 211's another side is connected with mounting panel 1. The X-axis limiting plate 214 can limit the X-axis sliding plate 211 to slide out of the X-axis limiting plate 214, the X-axis sliding plate 211 can slide in the sliding slot of the X-axis base plate 210 through a guide rail, and the sliding distance of the X-axis sliding plate 211 in the sliding slot of the X-axis base plate 210 can be controlled through the X-axis screw 212. For example, in some specific ways, threaded holes are formed in two sides of the sliding slot of the X-axis bottom plate 210, and the X-axis screw 212 and the X-axis limiting plate 214 are fixed by the threaded holes and screws on two sides of the sliding slot of the X-axis bottom plate 210.

Further, the sliding groove is of a dovetail groove structure, and the guide rail is of a trapezoidal guide rail structure matched with the dovetail groove structure. It should be noted that the present invention does not limit the specific types of the sliding groove and the guide rail, and can be made according to the requirements. In addition, the adjusting assembly 2 is combined with a dovetail groove structure and a screw rod, so that the distances of an X axis, a Y axis and a Z axis can be adjusted through the screw rod, the wire feeding and blowing assembly 3 can be adjusted according to the welding angle, and the rigidity is good.

Further, send a gas blowing device to still include pivot 4 and knob 5, Y axle bottom plate 201 downwardly extending both ends and form opening 2011, both ends one side of opening 2011 is equipped with the screw hole, the opposite side is equipped with the unthreaded hole, connecting block 31 is arranged in the opening, and connecting block 31's hole and open-ended screw hole and unthreaded hole registrate, pivot 4 passes connecting block 31's hole, the screw hole and the unthreaded hole of opening 2011 both sides, the one end of changeing and taking out 4 is equipped with knob 5 for turn the tight connecting block 31 and Y axle bottom plate 201. That is, except that the distance of X axle, Y axle and Z axle is adjusted through the screw rod, because connecting block 31 and Y axle bottom plate 201 also can rotate, that is to say send a gas blowing subassembly to have the mode of regulation of 4 dimensions, further richened the angle of regulation freedom of adjusting and sending a gas blowing subassembly 3, can adjust out required welding angle, adaptability is stronger.

Further, the diameter of the unthreaded hole in the two ends of the opening 2011 is larger than that of the threaded hole at the other end, and the unthreaded hole keeps away for the rotating shaft 4 when the rotating shaft 4 passes through the inner hole of the connecting block 31, the threaded holes and the unthreaded holes on the two sides of the opening 2012.

Further, the threaded hole of the opening 2011 is provided with scale marks, so that the torsion angle of the knob 5 can be conveniently recorded.

Further, the mounting plate is in an L shape at 1 position, one end of the mounting plate 1 is connected with the laser device 200, and the other end of the mounting plate 1 is connected with the X-axis sliding plate 211. The specific shape of the mounting plate 1 is not limited, and can be set as required.

The working principle of the invention is as follows: when the laser wire filling welding is carried out, the starting point of a welding wire needs to be accurately moved to the laser focus (or a designated position), the distance between an X axis, a Y axis and a Z axis can be adjusted through the adjusting assembly 2, and the wire feeding and blowing assembly can be adjusted from 4 degrees of freedom due to the fact that the connecting block 31 of the wire feeding and blowing assembly 3 is rotatably connected with the adjusting assembly 2, so that the welding wire can be accurately adjusted to the correct position (the laser focus or the designated position), meanwhile, gas and the welding wire are coaxial, plasma can be better dispersed, and the welding seam is protected from being oxidized. In addition, the wire feeding and air blowing integrated device has the advantages that the wire feeding and air blowing integrated device is compact in structure, the adjusting assembly 2 is combined by the dovetail groove and the screw rod, the rigidity is good, the precision is high, and the adaptability is enhanced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
