[0028] The present invention provides Figures 1 to 10 The laser cutting device used in the production and processing of environmental protection equipment shown in the figure includes a workbench 1 for assisting laser cutting, a support 26 is arranged outside the workbench 1, and both ends of the workbench 1 are connected with a rotating tube 24, and one end of the rotating tube 24 away from the support 26 is rotatably connected to the support 26. When in use, the workpiece of the environmental protection equipment is fixed on the workbench 1 to improve the efficiency of laser cutting; and the rotating tube 24 is rotatably arranged on the support 26, so that the inclination angle of the workbench 1 is adjustable, and the cutting angle is flexibly adjusted to meet various usage requirements.

[0029] Reference Figure 1 , Figure 2 As shown, a sliding channel 2 is provided on the workbench 1, and two sliding channels 2 are arranged. The two sliding channels 2 are respectively distributed at both ends of the workbench 1, and a square rod 3 is fixedly connected inside the sliding channel 2. A sliding sleeve 4 is slidably arranged on the square rod 3, and a ball bearing can be arranged between the sliding sleeve 4 and the square rod 3 to reduce the friction during the sliding process, which can be adjusted according to specific usage conditions.

[0030] Reference Figure 7 As shown, the top end of the sliding sleeve 4 is rotatably connected with a rotating sleeve 5 , and the bottom end of the rotating sleeve 5 is provided with a first air hole 6 , and the rotating sleeve 5 is always connected with the sliding sleeve 4 through the first air hole 6 .

[0031] Reference Figure 7 , Figure 8 As shown, the air cylinder 7 is rotatably connected to the rotating sleeve 5, so that the inclination angle of the air cylinder 7 is adjustable, and the air cylinder 7 is connected to the rotating sleeve 5. A square tube 8 is slidably connected to the inside of the air cylinder 7, and the square tube 8 passes through one end of the air cylinder 7 away from the rotating sleeve 5, and the square tube 8 is connected to the air cylinder 7.

[0032] Reference Fig. 9 , Fig.10As shown, the bottom of the square tube 8 is connected to an air pipe 9, which is located at the end of the square tube 8 away from the air cylinder 7. The bottom of the air pipe 9 is connected to a pressure box 11, and a serrated groove 12 is provided at the bottom end of the pressure box 11 to facilitate abutment against the protruding position of the workpiece.

[0033] In summary: the sliding sleeve 4 is slidably set on the square rod 3, the rotating sleeve 5 is rotatably set on the top of the sliding sleeve 4, the air cylinder 7 is rotatably set on the rotating sleeve 5, and the square tube 8 is slidably set inside the air cylinder 7 (when the square tube 8 extends outward from the inside of the air cylinder 7, the arm structure formed by the square tube 8 and the air cylinder 7 is longer, and when the square tube 8 is retracted into the inside of the air cylinder 7, the arm structure formed by the square tube 8 and the air cylinder 7 is shorter, and the position of the pressing box 11 is flexibly adjusted), so that the position of the pressing box 11 can be flexibly adjusted to meet the needs of workpieces of different shapes or to be squeezed at different positions of the workpiece, thereby improving the applicability of laser cutting devices used in the production and processing of environmental protection equipment.

[0034] An electric push rod 32 is hinged on the rotating sleeve 5, and one end of the electric push rod 32 away from the rotating sleeve 5 is hinged on the air cylinder 7. In specific use, after the position adjustment of the pressing box 11 is completed (the pressing box 11 is abutted at a suitable position of the workpiece according to the laser cutting requirements), the telescopic end of the electric push rod 32 is controlled to be retracted, and an oblique pulling force is applied to the air cylinder 7. The end of the air cylinder 7 away from the rotating sleeve 5 moves downward to drive the square tube 8 downward synchronously, and the pressing box 11 is pressed on the upper surface of the workpiece, pressing the workpiece from top to bottom, and the square tube 8 will not slide freely in the air cylinder 7 after the oblique pulling.

[0035] Taking into account the irregular upper surface of some workpieces, in order to improve the positioning stability, a groove 31 is provided at the bottom end of the press box 11, and a rotating box 13 is rotatably connected inside the groove 31. The rotating box 13 is connected to the press box 11, and an elastic band 14 is fixedly connected to the bottom of the rotating box 13. The elastic band 14 can be made of rubber, and a second air hole 15 is opened on the top of the rotating box 13.

[0036] A magnetic block 17 is fixedly embedded on the upper surface of the rotating box 13 , and an electromagnet 16 is installed on the inner wall of the pressing box 11 , and the electromagnet 16 cooperates with the magnetic block 17 .

[0037] Before laser cutting, the rotating box 13 is recovered to the inside of the groove 31, and the electromagnet 16 is started. The magnetism of the electromagnet 16 and the magnetic block 17 is opposite when they are close to each other. Under the action of the attraction, the position of the rotating box 13 is fixed, and the magnetic force is of appropriate size, so the rotating box 13 will not rotate at will; during laser cutting, the pressing box 11 is pressed on the workpiece, and when the inside of the rotating box 13 is inflated, the elastic band 14 is adaptively deformed and abuts against the surface of the workpiece, thereby improving the positioning stability. At this time, the attraction between the electromagnet 16 and the magnetic block 17 is greater than the air pressure force, and the rotating box 13 remains stationary.

[0038] After laser cutting, the electromagnet 16 is turned off to control the rotating box 13 to turn outward, and the second air hole 15 blows out air to blow away the debris on the workbench 1 caused by laser cutting. Rotating the rotating box 13 can change the air outlet angle of the second air hole 15 to expand the cleaning range.

[0039] An inner cavity 22 is provided inside the workbench 1, and an air compressor 25 is fixedly connected to the bottom of the workbench 1. The air compressor 25 cooperates with the inner cavity 22. The sleeve 4 is connected to the inner cavity 22 through a connecting pipe 23. The connecting pipe 23 is a telescopic hose and does not affect the movement of the sleeve 4. A first solenoid valve 10 is installed on the air pipe 9.

[0040] During specific use, the first solenoid valve 10 is opened, and the air compressor 25 inflates the interior of the rotating box 13 through the inner cavity 22, the connecting pipe 23, the sliding sleeve 4, the first air hole 6, the rotating sleeve 5, the air cylinder 7, the square tube 8, the air pipe 9, and the pressure box 11. After the inflation is completed, the first solenoid valve 10 is closed.

[0041] In order to prevent the sleeve 4 from sliding randomly, a square box 18 is fixedly connected to the outer wall of the sleeve 4, and a pressure column 21 is slidably arranged inside the square box 18. The pressure column 21 penetrates the end of the square box 18 away from the sleeve 4, and the pressure column 21 abuts against the inner wall of the sliding channel 2. A third air hole 19 is provided on the side wall of the sleeve 4, and the sleeve 4 is connected to the square box 18 through the third air hole 19. A second electromagnetic valve 20 is fixedly installed inside the third air hole 19. After the position adjustment of the pressure box 11 is completed, the second electromagnetic valve 20 is opened to supply gas to the inside of the square box 18, so that the pressure column 21 slides outward, and the pressure column 21 abuts against the inner wall of the sliding channel 2, and then the second electromagnetic valve 20 is closed, so that the sleeve 4 does not slide randomly, the stability of the workpiece positioning is improved, and laser cutting is convenient.

[0042] During specific use, a protective pad or other structure may be installed on the inner wall of the sliding channel 2 to increase the friction between the sliding channel 2 and the pressure column 21 .

[0043] In order to fix the inclination angle of the workbench 1, polygonal grooves 27 are provided on both sides of the support 26, and the polygonal grooves 27 can be regular hexagons, heptagons, etc. The polygonal grooves 27 surround the outer side of the corresponding rotating tube 24, and the outer side of the rotating tube 24 is fixedly connected with an air bag 28, and the air bag 28 cooperates with the corresponding polygonal groove 27. The rotating tube 24 is provided with a fourth air hole 29, and the air bag 28 is connected with the corresponding rotating tube 24 through the fourth air hole 29, and a third electromagnetic valve 30 is fixedly installed inside the fourth air hole 29.

[0044] After the inclination angle of the workbench 1 is adjusted, gas is transported to the interior of the airbag 28 through the rotating tube 24 and the fourth air hole 29. The airbag 28 expands and abuts against the inner wall of the polygonal groove 27, so that the rotating tube 24 does not rotate, thereby fixing the inclination angle of the workbench 1.

[0045] The inner cavity 22 and the air bag 28 are provided to inflate the rotating box 13, blow away debris, and position the sliding sleeve 4, thereby reducing the cost of using the equipment.

[0046] Working principle: Place the environmental protection equipment workpiece on the workbench 1. After the position adjustment of the pressure box 11 is completed (the pressure box 11 is abutted against the appropriate position of the workpiece according to the laser cutting requirements), the telescopic end of the electric push rod 32 is controlled to be retracted, and an oblique pulling force is applied to the air cylinder 7. The end of the air cylinder 7 away from the rotating sleeve 5 moves downward, driving the square tube 8 to move downward synchronously. The pressure box 11 is pressed on the upper surface of the workpiece, and the workpiece is squeezed from top to bottom.

[0047] The sliding sleeve 4 is slidably set on the square rod 3, the rotating sleeve 5 is rotatably set on the top of the sliding sleeve 4, the air cylinder 7 is rotatably set on the rotating sleeve 5, and the square tube 8 is slidably set inside the air cylinder 7, so that the position of the pressing box 11 can be flexibly adjusted to meet the needs of workpieces of different shapes or to be squeezed at different positions of the workpiece, thereby improving the applicability of laser cutting devices used in the production and processing of environmental protection equipment.

[0048] Before laser cutting, the rotating box 13 is recovered to the inside of the groove 31, and the electromagnet 16 is started. The electromagnet 16 and the magnetic block 17 are close to each other and have opposite magnetic properties. Under the action of the attraction, the position of the rotating box 13 is fixed, and the magnetic force is of appropriate size, so the rotating box 13 will not rotate at will; during laser cutting, the pressing box 11 is pressed on the workpiece, and when the inside of the rotating box 13 is inflated, the elastic band 14 is adaptively deformed and abuts against the surface of the workpiece.
