[0002] With the rapid development of modern manufacturing industry, the sheet metal processing industry has increasingly higher requirements for processing accuracy, efficiency and environmental protection performance. As a high-precision and high-efficiency processing method, laser cutting technology has been widely used in the field of sheet metal processing. Laser cutting machines use laser beams to perform non-contact cutting of metal sheets. They have the advantages of fast cutting speed, high precision, and small heat-affected zone, and can meet the processing needs of complex shapes and precise dimensions.

DETAILED DESCRIPTION

[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 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.

[0022] Example 1: Figure 1 and Figure 2 As shown, a laser cutting machine for sheet metal processing includes a fixing frame 100, a clamping mechanism 200, a linear driving mechanism 300, a cutting mechanism 400 and a gas processing mechanism 500.

[0023] The clamping mechanism 200 is installed on the fixing frame 100 , and the clamping mechanism 200 is used to clamp and fix the metal plate 600 ; the linear driving mechanism 300 is installed on the fixing frame 100 ; the cutting mechanism 400 is installed on the linear driving mechanism 300 , and the cutting mechanism 400 is used to cut the metal plate 600 .

[0024] The gas processing mechanism 500 includes a hollow ring 501, an air inlet groove 502, a hose 504, an air suction assembly 510 and a filter assembly 520. The hollow ring 501 is connected to the cutting mechanism 400; the air inlet groove 502 is provided on the inner wall of the hollow ring 501; the hose 504 is installed on the hollow ring 501; the air suction assembly 510 is used to absorb the gas generated by cutting the metal plate 600 through the hose 504 and the hollow ring 501; the filter assembly 520 is used to receive the gas delivered by the air suction assembly 510 and purify the gas.

[0025] Specifically, the metal plate 600 to be cut is clamped and fixed by using the clamping mechanism 200, and the metal plate 600 is cut by the cutting mechanism 400. During cutting, the position of the cutting mechanism 400 is adjusted by starting the linear driving mechanism 300.

[0026] When the cutting mechanism 400 cuts the metal plate 600 , the gas generated by the cutting can be purified by the gas processing mechanism 500 .

[0027] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the linear drive mechanism 300 includes a box 301 , a first motor 302 , a lead screw 303 , a moving seat 304 and a lead screw nut 305 .

[0028] The box body 301 is installed on the fixed frame 100, and the bottom of the box body 301 is open; the first motor 302 is installed on one side of the box body 301; the screw 303 passes through the box body 301 and is rotatably connected to the box body 301, and the screw 303 is fixedly connected to the power output shaft of the first motor 302; the moving seat 304 is slidably connected to the box body 301; the screw nut 305 is installed on the moving seat 304, and the screw nut 305 is sleeved on the screw 303.

[0029] Specifically, by starting the first motor 302, the power output shaft of the first motor 302 drives the lead screw 303 to rotate, and the rotating lead screw 303 drives the lead screw nut 305 to move horizontally, thereby driving the moving seat 304 to move horizontally.

[0030] like Figure 7 As shown, the cutting mechanism 400 includes a second motor 401 , a mounting plate 402 , a slide groove 403 , a slider 404 , a laser cutting machine 405 , a laser cutting head 406 and a tightening bolt 407 .

[0031] The second motor 401 is mounted on the moving seat 304; the mounting plate 402 is mounted on the power output shaft of the second motor 401; the slide groove 403 is provided on the mounting plate 402; the slider 404 passes through the slide groove 403 and is slidably connected with the slide groove 403, and the slider 404 is in the shape of an "I". The laser cutting machine 405 is mounted on the mounting plate 402; the laser cutting head 406 is mounted on the bottom surface of the slider 404; the tightening bolt 407 is threadedly connected with the slider 404, and the rod of the tightening bolt 407 is in contact with the mounting plate 402.

[0032] Specifically, when it is necessary to cut the metal plate 600, the laser cutting machine 405 is started, and the metal plate 600 is cut by the laser cutting head 406; when it is necessary to cut a circular groove on the metal plate 600, the second motor 401 is started, so that the power output shaft of the second motor 401 drives the mounting plate 402 to rotate, and then drives the slider 404 and the laser cutting head 406 to rotate, so that the laser cutting head 406 cuts a circular groove on the metal plate 600.

[0033] If it is necessary to adjust the size of the circular groove cut by the laser cutting head 406, before cutting, the tightening bolt 407 is rotated so that the tightening bolt 407 no longer contacts the slider 404, and then the slider 404 is moved to adjust the distance between the laser cutting head 406 and the power output shaft of the second motor 401. After the adjustment is completed, the tightening bolt 407 is rotated so that the tightening bolt 407 contacts the slider 404. By changing the distance between the laser cutting head 406 and the power output shaft of the second motor, the size of the circular groove cut by the laser cutting head 406 is adjusted.

[0034] like Figure 8-Figure 10 As shown, the gas processing mechanism 500 further includes a plurality of connecting rods 503 and a driving assembly 530. One end of the plurality of connecting rods 503 is connected to the hollow ring 501, and the other end of the plurality of connecting rods 503 is connected to the moving seat 304; the driving assembly 530.

[0035] Specifically, the hollow ring 501 is connected to the moving seat 304 through a plurality of connecting rods 503 . When the moving seat 304 moves, the hollow ring 501 is driven to move through the connecting rods 503 .

[0036] like Fig. 9 As shown, the air suction assembly 510 includes a high-pressure air pump 511 and a hollow cylinder 514. The high-pressure air pump 511 includes an air delivery pipe 512 and an air extraction pipe 513; the hollow cylinder 514 is connected to the air extraction pipe 513, and the hollow cylinder 514 is connected to the end of the hose 504 away from the hollow ring 501. A one-way valve is installed in the air delivery pipe 512, so that the water in the water tank 521 cannot enter the high-pressure air pump 511 through the air delivery pipe 512.

[0037] Specifically, by starting the high-pressure air pump 511 , the gas in the hollow cylinder 514 is extracted through the exhaust pipe 513 , and then the gas in the hollow ring 501 is transported to the hollow cylinder 514 through the hose 504 .

[0038] like Fig. 9 and Fig.10 As shown, the filter assembly 520 includes a water tank 521 , an exhaust pipe 522 , a rotating rod 523 , a plurality of stirring rods 524 , a rotating disk 525 , a plurality of through slots 526 and a second bevel gear 527 .

[0039] The water tank 521 is installed on the top surface of the box body 301, and the high-pressure air pump 511 is installed on the top surface of the water tank 521; the exhaust pipe 522 is installed on the top surface of the water tank 521; the rotating rod 523 penetrates the water tank 521 and is rotatably connected to the water tank 521, and one end of the rotating rod 523 extends into the hollow cylinder 514 and is rotatably connected to the hollow cylinder 514; multiple stirring rods 524 are all located in the water tank 521, and the multiple stirring rods 524 are all connected to the rotating rod 523; the turntable 525 is installed at one end of the rotating rod 523 away from the hollow cylinder 514, and the turntable 525 contacts the end of the exhaust pipe 522; multiple through grooves 526 are equidistantly opened on the turntable 525; the second bevel gear 527 is installed on one end of the rotating rod 523 located in the hollow cylinder 514.

[0040] Specifically, before use, water is injected into the water tank 521 through the exhaust pipe 522, and flocculants are added into the water tank 521. When in use, the high-pressure air pump 511 is started to transport the gas generated by cutting into the water tank 521, so that the water purifies the gas, removes particulate matter and gaseous pollutants in the gas, and the treated gas is discharged through the exhaust pipe 522.

[0041] By rotating the rotating rod 523, the plurality of stirring rods 524 are driven to rotate, thereby stirring the water in the water tank 521, so that the water and the flocculant are mixed, thereby facilitating the flocculant to flocculate the particles in the water.

[0042] like Fig. 9 and Fig.10 As shown, the driving assembly 530 includes a vertical rod 531, a fan blade 532 and a first bevel gear 533. The vertical rod 531 is rotatably mounted in the hollow cylinder 514; the fan blade 532 is mounted on the vertical rod 531; the first bevel gear 533 is fixedly sleeved on the vertical rod 531, and the first bevel gear 533 is meshed and connected with the second bevel gear 527.

[0043] Specifically, when the gas enters the hollow cylinder 514 through the hose 504 , the flow of the gas will drive the fan blades 532 to rotate, thereby driving the vertical rod 531 to rotate, and further driving the first bevel gear 533 to rotate.

[0044] Working principle: Before use, water and flocculant are added into the water inlet tank 521 through the exhaust pipe 522 to fill the water tank 521 with water.

[0045] First, the metal plate 600 to be cut is clamped and fixed by using the clamping mechanism 200 , and then the laser cutting machine 405 is started to cut the metal plate 600 by the laser cutting head 406 .

[0046] When it is necessary to cut a strip groove on the metal plate 600, the first motor 302 is started so that the power output shaft of the first motor 302 drives the screw 303 to rotate. The rotating screw 303 drives the screw nut 305 to move horizontally, thereby driving the moving seat 304 to move horizontally, and then driving the laser cutting head 406 to rotate, so that the laser cutting head 406 cuts a strip groove on the metal plate 600.

[0047] When a circular groove needs to be cut on the metal plate 600, the second motor 401 is started so that the power output shaft of the second motor 401 drives the mounting plate 402 to rotate, thereby driving the slider 404 and the laser cutting head 406 to rotate, so that the laser cutting head 406 cuts a circular groove on the metal plate 600.

[0048] When the metal plate 600 is cut, the high-pressure air pump 511 is started to extract the smoke gas generated by the cutting through the exhaust pipe 513, the hollow cylinder 514, the hose 504 and the hollow ring 501, and the smoke gas is transported to the water tank 521. The smoke gas is purified by the water in the water tank 521 to remove particulate matter and gaseous pollutants in the gas, and the treated gas is discharged through the exhaust pipe 522.

[0049] When the gas enters the hollow cylinder 514 through the hose 504, the gas will blow the fan blades 532 to rotate, thereby driving the vertical rod 531 to rotate, and then driving the first bevel gear 533 to rotate, and then meshing and driving the second bevel gear 527 to rotate, and then driving the rotating rod 523 to rotate, and then driving the multiple stirring rods 524 to rotate, thereby stirring the water in the water tank 521. By stirring the water in the water tank 521, the water and the gas are in contact more frequently, which improves the purification effect of the gas. Stirring the water will also mix the water and the flocculant, thereby facilitating the flocculant to flocculate the particles in the water.

[0050] When the rotating rod 523 rotates, the turntable 525 will be driven to rotate, and the through groove 526 on the rotating turntable 525 will be intermittently connected with the exhaust pipe 522, so that the gas in the water tank 521 is intermittently discharged, thereby increasing the residence time of the gas in the water tank 521, so that the gas and water have a longer contact time, thereby improving the effect of water on purifying smoke gas.

[0051] Example 2: Figure 3 and Figure 4 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: The clamping mechanism 200 includes two groups of clamping components 210 , a transmission component 220 , a striking component 230 and a connecting component 240 .

[0052] The clamping assembly 210 includes a support plate 211, a pressure plate 212, a guide rod 213, an adjusting screw 214 and a cross plate 215. The support plate 211 is installed on the fixing frame 100, and the support plate 211 is used to support the metal plate 600; the pressure plate 212 is located directly above the support plate 211, and a threaded barrel is rotatably installed on the pressure plate 212, and the threaded barrel is rotatably connected to the pressure plate 212; the guide rod 213 is installed on the top surface of the support plate 211, and the guide rod 213 passes through the pressure plate 212 and is slidably connected to the pressure plate 212; the adjusting screw 214 passes through the threaded barrel on the pressure plate 212, and the adjusting screw 214 is threadedly connected to the threaded barrel, and the lower end of the adjusting screw 214 is rotatably connected to the support plate 211; the cross plate 215 is installed on the upper end of the adjusting screw 214.

[0053] Specifically, the metal plate 600 is placed between the support plate 211 and the pressure plate 212, and the adjusting screw 214 is driven to rotate by rotating the cross plate 215, thereby causing the threaded barrel to move downward, thereby driving the pressure plate 212 to move downward, and then the pressure plate 212 cooperates with the support plate 211 to clamp and fix the metal plate 600.

[0054] like Figure 5 As shown, the transmission assembly 220 includes a mounting block 221, a rotating shaft 222 and a second sprocket 223. The mounting block 221 is mounted on the support plate 211; the rotating shaft 222 is rotatably mounted on the mounting block 221, and a slot is provided on the rotating shaft 222; and the second sprocket 223 is fixedly sleeved on the rotating shaft 222.

[0055] like Figure 3-Figure 5 As shown, the striking assembly 230 includes two hollow rods 231 , a plurality of rubber rods 232 , a plurality of rubber balls 233 , two pulleys 234 and a transmission belt 235 .

[0056] The two ends of the two hollow rods 231 are rotatably connected to the two supporting plates 211 respectively; multiple rubber rods 232 are respectively installed on the two hollow rods 231; multiple rubber balls 233 are respectively installed on the multiple rubber rods 232; two pulleys 234 are respectively fixedly sleeved on the two hollow rods 231; and a transmission belt 235 is sleeved on the two pulleys 234.

[0057] Specifically, when the metal plate 600 is thicker, when the circular groove is cut on the metal plate 600, the cut waste will tilt when falling, and the tilted waste will be stuck in the circular groove and cannot fall. At this time, by rotating any one of the hollow rods 231, and driving the other hollow rod 231 to rotate through the pulley 234 and the transmission belt 235, when the two hollow rods 231 rotate, they will drive the multiple rubber rods 232 to rotate, and then drive the multiple rubber balls 233 to rotate and hit the metal plate 600, so that the metal plate 600 vibrates, thereby shaking off the waste stuck in the circular groove.

[0058] like Figure 5 As shown, the connecting assembly 240 includes an insertion rod 241 and a handle 242. The insertion rod 241 penetrates the hollow rod 231 and is slidably connected to the hollow rod 231, and the insertion rod 241 is plugged into a slot on the rotating shaft 222; the handle 242 is installed at one end of the insertion rod 241 away from the rotating shaft 222.

[0059] Specifically, by moving the handle 242, the insertion rod 241 will be driven to move, and when the insertion rod 241 is plugged into the rotating shaft 222, the rotating shaft 222 is rotated at this time, and the hollow rod 231 will be driven to rotate through the insertion rod 241. When the insertion rod 241 is separated from the rotating shaft 222, the rotating shaft 222 is rotated, and the hollow rod 231 will not rotate.

[0060] like Figure 6 As shown, the linear drive mechanism 300 further includes a first sprocket 306 and a chain 307. The first sprocket 306 is fixedly sleeved on the lead screw 303; the chain 307 is sleeved on the first sprocket 306 and the second sprocket 223.

[0061] Specifically, when the lead screw 303 rotates, it drives the first sprocket 306 to rotate, and then drives the second sprocket 223 to rotate through the chain 307, and then drives the rotating shaft 222 to rotate.

[0062] Working principle: In actual use, when the metal plate 600 is thicker, when a circular groove is cut on the metal plate 600, the cut waste will tilt when falling, and the tilted waste will be stuck in the circular groove and cannot fall.

[0063] When it is necessary to remove the waste in the circular groove, without cutting, the handle 242 is first pushed to drive the insertion rod 241 to move so that the end of the insertion rod 241 is plugged into the rotating shaft 222. Then, by starting the first motor 302, the lead screw 303 is driven to rotate, which will drive the first sprocket wheel 306 to rotate, and then drive the second sprocket wheel 223 to rotate through the chain 307, and then drive the rotating shaft 222 to rotate, and then drive the hollow rod 231 to rotate through the insertion rod 241.

[0064] When one hollow rod 231 rotates, it will drive another hollow rod 231 to rotate through the pulley 234 and the transmission belt 235. When the two hollow rods 231 rotate, they will drive multiple rubber rods 232 to rotate, and then drive multiple rubber balls 233 to rotate and hit the metal plate 600, causing the metal plate 600 to vibrate, thereby shaking off the waste stuck in the circular groove.
