In addition, the absorption part can be easily disassembled and installed through the plug-in part, which is conducive to maintenance.

[0004] When cutting metal plates, a laser cutter usually needs to adjust the distance between its laser head and the metal plate to better control the cutting depth. However, in the above-mentioned structure, the impurity absorber rises and falls synchronously with the laser cutter during use. When the laser cutter is far away from the metal plate, the absorption effect of the impurity absorber will be greatly reduced. Utility Model Content

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 5The utility model discloses a laser cutting device for automobile guard plate production, comprising a base 1, a slide 4 movably mounted above the base 1, a lifting cylinder 5, the lifting cylinder 5 being fixed to one side of the slide 4, and a laser nozzle 14 being mounted on the telescopic end of the lifting cylinder 5; a shaft sleeve 13, the shaft sleeve 13 being arranged at the upper end of the laser nozzle 14, and the shaft sleeve 13 being rotatably connected to the lifting cylinder 5; a smoker 17, the side of the smoker 17 facing the laser nozzle 14 being a smoke inlet end, and the smokers 17 being installed at equal intervals A connecting piece is provided on the periphery of the sleeve 13 and between the smoker 17 and the first hinge seat 15; the connecting piece includes a first hinge seat 15 fixed to the outside of the sleeve 13 and a second hinge seat 16 fixed to the upper end of the smoker 17, a rotating shaft 21 is installed between the first hinge seat 15 and the second hinge seat 16, and an installation cavity 20 is opened on both sides of the first hinge seat 15, a clockwork spring 22 is installed inside the installation cavity 20, and the clockwork spring 22 is used to drive the smoker 17 to rotate toward the direction close to the laser nozzle 14.

[0023] In this solution, it should be noted that when the laser nozzle 14 is close to the metal plate, the smoker 17 slides in the direction away from the laser nozzle 14, so that the air inlet surface of the smoker 17 is close to the metal plate to achieve smoke suction. When the laser nozzle 14 is far away from the metal plate, the smoker 17 slides in the direction close to the laser nozzle 14, so that multiple smokers 17 are enclosed on the outside of the laser nozzle 14 to prevent smoke from escaping and improve the smoke suction effect.

[0024] like Figure 4 and Figure 5 As shown, in order to prevent the smoker 17 from rotating excessively toward the laser nozzle 14, a limit stop bar 23 is integrally formed at the lower end of the first hinge seat 15. The angle between the limit stop bar 23 and the horizontal plane is an acute angle, which is used to limit the rotation of the second hinge seat 16 toward the shaft sleeve 13.

[0025] like Figure 1 As shown, in order to facilitate the collection of waste residues during the processing of automobile guard plates, a waste trough is provided in the base 1 to facilitate the collection of waste. In addition, limiting grooves 6 are symmetrically opened on both side walls of the waste trough, and a movable frame 8 is slidably installed on the upper end of the waste trough. Preferably, the movable frame 8 is symmetrically fixed with support legs at one end located on the outside of the base 1, and rollers are installed at the lower end of the support legs. Limiting sliders 7 are provided at both ends of the movable frame 8 and are slidably connected to the limiting grooves 6. The movable frame 8 is pushed, and the sliding connection between the limiting grooves 6 and the limiting sliders 7 can realize the movement of the movable frame 8 on the base 1, which is conducive to the loading and unloading of automobile guard plates on the movable frame 8.

[0026] like Figure 1 and Figure 2As shown, in order to facilitate the processing of automobile guard plates, a negative pressure pump 10 is installed in the waste trough, and a supporting frame 9 is provided on the inner side of the movable frame 8. The supporting frame 9 is a grid-shaped structure, and protective covers 11 are installed on the supporting frame 9 at equal intervals. The upper end of the protective cover 11 is in an open state, and a negative pressure suction cup 12 connected to the pipeline of the negative pressure pump 10 is fixed inside the protective cover 11. In order to avoid wear of the upper end of the negative pressure suction cup 12 by the automobile guard plate, the top of the negative pressure suction cup 12 provided in this embodiment is lower than the upper surface of the protective cover 11.

[0027] In this solution, the negative pressure pump 10 is used to enable the negative pressure suction cup 12 to adsorb the metal plate, thereby achieving fixation of the metal plate.

[0028] like Figure 1 As shown, in order to facilitate the adjustment of the position of the laser nozzle 14 in the plane, a mounting bracket 2 is fixed on the upper surface of the base 1, and a beam 3 is installed inside the mounting bracket 2 along the axial sliding direction. The beam 3 is slidably connected to the slide 4, and the sliding direction of the beam 3 and the sliding direction of the slide 4 are perpendicular to each other in the plane, thereby realizing the adjustment of the laser nozzle 14 to any position in the plane. In this solution, the beam 3 and the slide 4 are respectively driven by external driving devices.

[0029] like Figure 3 As shown, in order to facilitate the movement of the smoker 17, the lower end of the smoker 17 provided in this embodiment is in a conical structure, and second balls 19 are provided at equal intervals on the outer side of the smoker 17 near the position of the conical structure, and a first ball 18 is installed at the bottom of the second ball 19. Through the cooperation of the first ball 18 and the second ball 19, the smoker 17 can slide on the metal plate, which is beneficial to the horizontal position adjustment of the smoker 17 and the laser nozzle 14.

[0030] The working principle and usage process of the present invention are as follows: when in use, a metal plate is placed on the carrier 9, and the negative pressure pump 10 is started. The negative pressure suction cup 12 is used to adsorb the metal plate through the negative pressure pump 10, thereby fixing the metal plate. The movable frame 8 can be pushed into the inside of the base 1 through the sliding connection between the limiting groove 6 and the limiting slider 7. At this time, the position of the laser nozzle 14 is adjusted by adjusting the position of the crossbeam 3 and the slide 4. The lifting cylinder 5 is started to adjust the height of the laser nozzle 14, and the lower end of the smoker 17 is made to be against the upper surface of the metal plate. The elastic force of the clockwork spring 22 is used to make the second hinged seat 16 drive the smoker 17 to move toward the laser nozzle 14, so that the lower end of the smoker 17 can squeeze the metal plate, further improving the stability of the metal plate cutting process and improving the cutting accuracy.

[0031] When the laser nozzle 14 is close to the metal plate, the smoker 17 slides in the direction away from the laser nozzle 14, so that the air inlet surface of the smoker 17 is close to the metal plate to achieve smoke suction. When the laser nozzle 14 is far away from the metal plate, the smoker 17 slides in the direction close to the laser nozzle 14, so that multiple smokers 17 are enclosed on the outside of the laser nozzle 14 to prevent smoke from escaping and improve the smoke suction effect.
