[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides a technical solution:

[0025] See also Figures 1 to 5 A three-dimensional five-axis laser cutting machine comprises a laser cutting machine body 1 and a support table 2 fixedly connected to the upper side of the laser cutting machine body 1, a sputtering prevention component 3 is provided outside the nozzle of the laser cutting machine body 1, and the sputtering prevention component 3 comprises a protective cover 31 fixedly connected to the outside of the nozzle of the laser cutting machine body 1;

[0026] A plurality of first slide grooves 32 are provided on the front and rear sides inside the protective cover 31, and a first slider 33 is slidably connected inside the plurality of first slide grooves 32, and a first baffle plate 35 is fixedly connected to a side of the plurality of first sliders 33 away from the first slide groove 32, and a plurality of return springs 34 are fixedly connected to the upper sides of the two first baffle plates 35, and the top ends of the plurality of return springs 34 are fixedly connected to the upper side of the inner part of the protective cover 31, and two support plates 36 are fixedly connected to the opposite surfaces of the two first baffle plates 35, and a guide assembly 37 is provided on the inner lower side of the two support plates 36.

[0027] The guide assembly 37 includes a plurality of movable grooves 371 provided on the lower inner side of the first baffle 35 . The upper inner side of the movable grooves 371 is connected to the limiting grooves 372 . The limiting grooves 372 are internally slidably connected to the limiting rods 373 . The bottom end of the limiting rods 373 is fixedly connected to the rollers 374 .

[0028] The rollers 374 are slidably connected in the movable grooves 371 , and the plurality of rollers 374 move downward and are pressed and contacted with the upper side of the support platform 2 .

[0029] By adopting the above technical solution, first, after the nozzle of the laser cutting machine body 1 moves above the support table 2, the protective cover 31 on its outside will also move with it. When the nozzle of the laser cutting machine body 1 starts to process the workpiece, it needs to move downward. At this time, the protective cover 31 gradually wraps around the outside of the workpiece, and the two first baffles 35 inside the protective cover 31 will contact the workpiece and move upward after being squeezed by the workpiece. At this time, the first sliders 33 on the far side of the two first baffles 35 both slide in the first slide groove 32. When the height of the protective cover 31 changes, the reset spring 34 above the protective cover 31 will push the first baffle 35, so that the first baffle 35 is always in contact with the workpiece, and before the first baffle 35 contacts the workpiece, the movable groove 371 is The upper roller 374 contacts the workpiece first, and when the protective cover 31 moves, the roller 374 will roll on the surface of the workpiece. When the protective cover 31 moves up and down, the limit rod 373 above the roller 374 moves up and down in the limit groove 372 above the movable groove 371, so that the roller 374 is always in contact with the surface of the workpiece, and the high-energy laser beam splashed by the nozzle of the laser cutting machine body 1 and the sparks generated during the cutting process will be blocked by the protective cover 31 and the first baffle 35. Since the nozzle of the laser cutting machine body 1 moves randomly, the protective cover 31 and the first baffle 35 always wrap the workpiece, thereby avoiding the high-energy laser beam splashed by the nozzle of the laser cutting machine body 1 and the sparks generated during the cutting process from flowing out and affecting the normal operation safety problem.

[0030] Specifically, Figure 2 As shown, soot blowing components 4 are provided on both sides of the left and right interior of the protective cover 31. The two soot blowing components 4 include four second slide grooves 41 opened on both sides of the interior of the protective cover 31. The interiors of the four second slide grooves 41 are all slidably connected with second sliders 42, and the side of two adjacent second sliders 42 away from the second slide groove 41 is fixedly connected with the same second baffle 43.

[0031] After the two support plates 36 move upward, they are pressed and contacted with the lower sides of the two second baffles 43 respectively, and the support plates 36 are in an "L" shape.

[0032] A plurality of balls are rollingly connected on both sides of the second sliding block 42 , and the second sliding block 42 is slidably connected in the second sliding groove 41 via the balls.

[0033] Air inlets 44 are provided on both sides of the left and right inside of the protective cover 31, and ventilation ducts 45 are connected to the left and right sides of the protective cover 31. Fans 46 are fixedly installed inside the two ventilation ducts 45. The two air inlets 44 are respectively connected to the two ventilation ducts 45, and the two air inlets 44 are opened at an angle. When the two second baffles 43 are not moved upward, they respectively block the two air inlets 44.

[0034] The opposite surfaces of the two first baffles 35 are fixedly connected with scrapers 5 . The scrapers 5 are trapezoidal in shape, and the inclined surfaces thereof are both facing the inside of the protective cover 31 .

[0035] By adopting the above technical solution, firstly, during the upward movement of the two first baffles 35, the two support plates 36 fixed on the other side of the first baffles 35 will contact the two second baffles 43, and the two second baffles 43 will be gradually lifted up with the cooperation of the two first baffles 35. At this time, the two second sliders 42 of the second baffle 43 on one side of the protective cover 31 will slide in the second slide groove 41 through the ball bearings. During the gradual upward movement of the second baffle 43, the air inlet 44 blocked by the second baffle 43 will be exposed. At this time, the airflow generated by the fan 46 inside the ventilation duct 45 will be passed through The air is blown into the protective cover 31 through the inclined air inlet 44, and the waste chips and spark residues on the surface of the workpiece are blown away. In the process of the protective cover 31 moving above the workpiece, the scraper 5 between the two first baffles 35 will also scrape off the waste chips and spark residues on the surface of the workpiece. Since the waste chips and spark residues are blown away, and the scraper 5 will also scrape off the surface of the workpiece, the waste chips and spark residues are always in the protective cover 31, which effectively prevents the waste chips and spark residues attached to the surface of the workpiece from affecting the cutting effect of the nozzle of the laser cutting machine body 1, thereby ensuring the processing quality of the workpiece.

[0036] Working principle: First, when the nozzle of the laser cutting machine body 1 moves, the protective cover 31 will also move with it and gradually wrap around the outside of the workpiece. After the two first baffles 35 come into contact with the workpiece, they will be squeezed upward by the workpiece, so that the first sliders 33 on the surfaces of the two first baffles 35 slide in the first slide grooves 32, and the extrusion of the return spring 34 will make the first baffles 35 always fit the workpiece. At the same time, the roller 374 inside the movable groove 371 will also come into contact with the workpiece and roll on the surface of the workpiece. Because the limit rod 373 above the roller 374 moves up and down in the limit groove 372 above the movable groove 371, the roller 374 is always in contact with the surface of the workpiece, and the laser cutting machine body The high-energy laser beam splashed by the nozzle 1 and the sparks generated during the cutting process will be blocked by the protective cover 31 and the first baffle 35. After the two first baffles 35 move upward, the support plate 36 will lift the second baffle 43, so that the second slider 42 on the surface of the second baffle 43 slides in the second slide groove 41 through the ball bearing, and the air inlet 44 blocked by the second baffle 43 will be exposed, and the air flow generated by the fan 46 in the ventilation duct 45 will be blown into the protective cover 31 through the inclined air inlet 44, so that the waste chips and spark residues on the surface of the workpiece are blown, and at the same time, the scraper 5 between the two first baffles 35 will also scrape off the waste chips and spark residues on the surface of the workpiece.
