DETAILED DESCRIPTION

[0035] The present invention provides Figures 1 to 10 The laser cutting device shown in the figure, used in the production and processing of environmental protection equipment, includes a workbench 1 for assisting laser cutting. A support 26 is provided on the exterior of the workbench 1. A rotating tube 24 is connected to each end of the workbench 1, with the end of the rotating tube 24, distal from the support 26, pivotally connected to the support 26. During use, the environmental protection equipment workpiece is secured to the workbench 1 to improve laser cutting efficiency. Furthermore, the rotating tube 24 is pivotally attached to the support 26, allowing the workbench 1 to tilt at an adjustable angle, allowing for flexible adjustment of the cutting angle to meet diverse usage requirements.

[0036] Reference Figure 1 、 Figure 2 As shown, a sliding channel 2 is provided on the workbench 1. There are two sliding channels 2, which are respectively distributed at both ends of the workbench 1. A square rod 3 is fixedly connected to the inside of the sliding channel 2. A sliding sleeve 4 is slidingly provided on the square rod 3, and a ball bearing can be provided 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.

[0037] Reference Figure 7 As shown, the top end of the sliding sleeve 4 is rotatably connected to the 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 to the sliding sleeve 4 through the first air hole 6 .

[0038] 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. The interior of the air cylinder 7 is slidably connected to a square tube 8, 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.

[0039] Reference Figure 9 、 Figure 10 As shown, the bottom of the square tube 8 is connected to the 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 the pressure box 11, and the bottom end of the pressure box 11 is provided with a serrated groove 12 to facilitate abutment against the protruding position of the workpiece.

[0040] In summary: the sliding sleeve 4 is slidingly 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 slidingly set inside the air cylinder 7 (when the square tube 8 extends outward from the inside of the air cylinder 7, the support 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 support arm structure formed by the square tube 8 and the air cylinder 7 is shorter, and the position of the press box 11 can be flexibly adjusted), so that the position of the press 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.

[0041] An electric push rod 32 is hinged on the rotating sleeve 5, and the 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 against the appropriate position of the workpiece according to the requirements of laser cutting), the telescopic end of the electric push rod 32 is controlled to retract, 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 downward synchronously. The pressing box 11 is pressed against the upper surface of the workpiece, squeezing the workpiece from top to bottom. After the oblique pulling, the square tube 8 will not slide freely in the air cylinder 7.

[0042] 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 pressing box 11, and the internal rotation of the groove 31 is connected to the rotating box 13, and the rotating box 13 is connected to the pressing box 11. The bottom of the rotating box 13 is fixedly connected with an elastic band 14, and the elastic band 14 can be made of rubber. A second air hole 15 is opened on the top of the rotating box 13.

[0043] 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 .

[0044] Before laser cutting, the rotary 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 attractive force, the position of the rotary box 13 is fixed, and the magnetic force is of appropriate size, so the rotary box 13 will not rotate at will; during laser cutting, the pressing box 11 is pressed on the workpiece. When the inside of the rotary box 13 is inflated, the elastic band 14 adaptively deforms and abuts against the surface of the workpiece, thereby improving the positioning stability. At this time, the attractive force between the electromagnet 16 and the magnetic block 17 is greater than the air pressure force, and the rotary box 13 remains stationary.

[0045] After laser cutting, the electromagnet 16 is turned off, the rotary box 13 is controlled to turn outward, and air is ejected outward from the second air hole 15 to blow away the debris generated by laser cutting on the workbench 1. Rotating the rotary box 13 can change the air outlet angle of the second air hole 15 to expand the cleaning range.

[0046] 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.

[0047] During specific use, open the first solenoid valve 10, 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, close the first solenoid valve 10.

[0048] To prevent the sleeve 4 from sliding freely, a square box 18 is fixedly connected to the outer wall of the sleeve 4. A pressure column 21 is slidingly provided inside the square box 18. The pressure column 21 passes through the end of the square box 18 away from the sleeve 4 and 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. The sleeve 4 is connected to the square box 18 through the third air hole 19. A second solenoid valve 20 is fixedly installed inside the third air hole 19. After the position adjustment of the pressure box 11 is completed, the second solenoid valve 20 is opened to supply gas to the interior of the square box 18, causing the pressure column 21 to slide outward and abut against the inner wall of the sliding channel 2. Then, the second solenoid valve 20 is closed, so that the sleeve 4 does not slide freely, thereby improving the stability of the workpiece positioning and facilitating laser cutting.

[0049] 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 .

[0050] To maintain the tilt angle of the workbench 1, polygonal grooves 27 are provided on both sides of the support 26. These grooves can be regular hexagons, heptagons, or other shapes. These grooves surround the outer sides of the corresponding rotating tubes 24. An airbag 28 is fixedly connected to the exterior of the rotating tubes 24, which engages with the corresponding polygonal grooves 27. A fourth air hole 29 is provided on the rotating tubes 24, through which the airbag 28 communicates with the corresponding rotating tubes 24. A third solenoid valve 30 is fixedly mounted within the fourth air hole 29.

[0051] 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.

[0052] 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.

[0053] Working principle: Place the environmental protection equipment workpiece on the workbench 1. After the position adjustment of the press box 11 is completed (the press 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 downward synchronously. The press box 11 is squeezed on the upper surface of the workpiece, squeezing the workpiece from top to bottom.

[0054] 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 squeezed at different positions of the workpiece, thereby improving the applicability of laser cutting devices in the production and processing of environmental protection equipment.

[0055] Before laser cutting, the rotary 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 attractive force, the position of the rotary box 13 is fixed, and the magnetic force is of appropriate size, so the rotary box 13 will not rotate at will; during laser cutting, the pressing box 11 is squeezed on the workpiece, and when the inside of the rotary box 13 is inflated, the elastic band 14 adaptively deforms and abuts against the surface of the workpiece.
