Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 5As shown in the figure, a water-guided laser cutting machine according to an embodiment of the present invention includes a machine table 1; an operation panel 2 is fixedly connected to the top surface of the machine table 1; grooves are evenly formed on the top surface of the operation panel 2; a translation mechanism 3 is arranged on the top surface of the machine table 1; a support plate 4 is fixedly connected to the moving seat of the translation mechanism 3; a pair of laser cutting heads 5 are arranged on the bottom surface of one end of the support plate 4 away from the translation mechanism 3, and are used for emitting laser beams to cut and process metal workpieces; During operation, the workpiece to be processed is placed on the operation panel 2 of the machine table 1. The translation mechanism 3 moves, driving the support plate 4 and the two laser cutting heads 5 to move. The two laser cutting heads 5 emit laser beams downward, and the two laser beams successively cut the workpiece along the same cutting line; thereby effectively reducing the time required for workpiece cutting and improving the processing efficiency of the workpiece.

[0023] As Figures 2 to 5 As shown in the figure, a disc 6 is bolted to the bottom surface of one end of the support plate 4 away from the translation mechanism 3; rotating mechanisms are arranged on both sides of the disc 6; C-shaped frames 7 are slidably installed on both sides of the outer ring of the disc 6; the C-shaped frames 7 can slide and rotate along the outer ring of the disc 6; the two laser cutting heads 5 are respectively arranged at the bottoms of the two C-shaped frames 7; An external gear ring 8 is fixedly connected to the outer ring of the disc 6; the C-shaped frame 7 is sleeved outside the external gear ring 8; a first gear 9 is rotatably installed in the middle of the C-shaped frame 7; the first gear 9 meshes with the external gear ring 8; the rotating shaft of the first gear 9 penetrates through the top of the C-shaped frame 7; a first motor 10 is fixedly connected to the side of the C-shaped frame 7 away from the disc 6; first synchronous pulleys 11 are fixedly connected to the outer circles of the top of the output shaft of the first motor 10 and the top of the rotating shaft of the first gear 9; a first synchronous belt 12 is sleeved on the outer circles of the two first synchronous pulleys 11; During operation, the translation mechanism 3 drives the support plate 4 to move, drives the disc 6 to move, and drives the two laser cutting heads 5 to move. Moreover, one of the laser cutting heads 5 that first contacts the workpiece moves along the set cutting line to emit a laser beam for cutting. At this time, the other laser cutting head 5 that later contacts the workpiece needs to timely adjust the position where the laser beam irradiates downward to ensure that the moving trajectories of the laser beams of the two laser cutting heads 5 are completely consistent with the set cutting line. Therefore, the first motor 10 drives the first synchronous pulley 11 to rotate. Through the transmission of the first synchronous belt 12 and the first synchronous pulley 11, the first gear 9 is driven to rotate inside the C-shaped frame 7. The first gear 9 meshes with the external gear ring 8, causing the C-shaped frame 7 to slide along the disc 6, controlling and adjusting the position of the laser cutting head 5, thereby controlling the positions where the two laser cutting heads 5 emit laser beams. The two laser cutting heads 5 on both sides are adjusted by the two rotation mechanisms on both sides, enabling the laser beams emitted by the two laser cutting heads 5 to be kept on the same cutting line to cut the workpiece, improving the cutting efficiency and accuracy. At the same time, the cutting of complex graphics of the workpiece can be completed.

[0024] As Figures 2 to 7 shown, circular guide grooves 13 are formed on both the top and bottom surfaces of the outer ring of the disc 6; a plurality of mounting grooves 14 are formed on both the top and bottom surfaces of one side of the C-shaped frame 7 close to the disc 6; a through groove 15 is formed in the middle of the mounting groove 14; a sliding seat 16 is bolted inside the mounting groove 14; one end of the sliding seat 16 close to the disc 6 penetrates through the through groove 15; a roller 17 is rotatably mounted on the outer ring of one end of the sliding seat 16 close to the disc 6; the roller 17 is in sliding fit with the circular guide groove 13; During operation, when the first gear 9 meshes with the external gear ring 8 and drives the C-shaped frame 7 to slide along the disc 6, the C-shaped frame 7 drives a plurality of sliding seats 16 and rollers 17 to move along the circular guide groove 13. Through the sliding fit between the roller 17 and the circular guide groove 13, not only can the situation that the C-shaped frame 7 disengages from the outer ring of the disc 6 be avoided, but also the stability of the movement of the C-shaped frame 7 is improved, thereby improving the stability of the movement of the laser cutting head 5, improving the stability of the laser beam emitted by the laser cutting head 5, and then improving the cutting accuracy.

[0025] As Figures 2 to 5As shown, a sliding beam 18 is fixedly connected to the bottom surface of the C-shaped frame 7; a chute is provided on the bottom surface of the sliding beam 18; a lead screw 19 is rotatably installed inside the chute of the sliding beam 18; one end of the lead screw 19 away from the disc 6 rotatably penetrates through the outer wall of the sliding beam 18; a slider 20 is slidably installed inside the chute of the sliding beam 18; the lead screw 19 is in threaded cooperation with the slider 20; the laser cutting head 5 is fixedly connected to the bottom surface of the slider 20; a second motor 21 is fixedly connected to the top surface of the end of the sliding beam 18 away from the disc 6; a second synchronous pulley 22 is fixedly connected to the outer ring of one end of the lead screw 19 away from the disc 6 and the outer ring of the output shaft of the second motor 21; a second synchronous belt 23 is sleeved on the outer rings of the two second synchronous pulleys 22; During operation, the second motor 21 drives the second synchronous pulley 22 to rotate. Through the transmission of the second synchronous belt 23 and the second synchronous pulley 22, the lead screw 19 is driven to rotate, the slider 20 is driven to move along the sliding beam 18, the laser cutting head 5 is driven to move, the distance between the two laser cutting heads 5 is controlled and adjusted, so as to control and adjust the distance between the laser beams emitted by the two laser cutting heads 5; not only can the cutting work be carried out on workpieces of different specifications, improving the scope of application; but also by controlling and adjusting the distance between the two laser cutting heads 5, the influence between the water flows ejected by the two laser cutting heads 5 can be reduced.

[0026] As Figure 2 、 Figure 3 、 Figure 7 and Figure 8 shown, an air beam 24 is arranged in the middle of the bottom surface of the disc 6; an opening is provided on the bottom surface of the air beam 24; the air beam 24 is communicated with an air pump through an air pipe; the air beam 24 is located between the two laser cutting heads 5; During operation, when the laser cutting head 5 emits a laser beam for laser cutting, it will eject a water flow to guide the laser beam downward. When the water flow hits the workpiece, the water flow will generate splashing water droplets, and the splashing water flow will affect the normal operation of the laser beam emitted by the other laser cutting head 5; therefore, when the two laser cutting heads 5 cut the workpiece, the air pump transports the air flow into the interior of the air beam 24 and then ejects it downward from the air beam 24, forming a downward flowing air curtain between the two laser cutting heads 5 to intercept the splashing water droplets and reducing the interference between the two laser cutting heads 5.

[0027] As Figures 7 to 9 shown, a rotating seat 25 is rotatably installed in the middle of the bottom surface of the disc 6; the air beam 24 is arranged at the bottom of the rotating seat 25; a face gear 26 is fixedly connected to the outer ring of the bottom of the rotating seat 25; a third motor 27 is fixedly connected to the bottom surface of the disc 6; a second gear 28 is fixedly connected to the outer ring of the output shaft of the third motor 27; the second gear 28 meshes with the face gear 26; A hinge seat 29 is bolted to the bottom of the turntable 25; the bottom of the hinge seat 29 is rotatably connected to the top of the air beam 24; electric push rods 30 are hinged to both sides of the hinge seat 29; the bottom of the electric push rods 30 is hinged to the top surface of the air beam 24; During operation, the third motor 27 drives the second gear 28 to rotate, driving the face gear 26 and the turntable 25 to rotate, driving the air beam 24 to rotate, so that the air beam 24 can always be kept between the two laser cutting heads 5; At the same time, the electric push rods 30 on both sides push the two ends of the air beam 24 to rotate, so that the air beam 24 can be tilted, so that the ejected air curtain is tilted, reducing the flow of the air flow to the laser beam cutting positions of the two laser cutting heads 5 on both sides; It not only effectively intercepts the splashing water droplets generated by the two laser cutting heads 5, but also reduces the cutting influence of the air flow on the laser beam emitted by the laser cutting heads 5.

[0028] As Figures 8 to 11 shown, a partition 31 is fixedly connected inside the air beam 24; a plurality of straight grooves are evenly formed in the partition 31; baffles 32 are rotatably installed on both sides of the bottom of the air beam 24; arc grooves 33 are formed at both ends of the two sides inside the air beam 24; both ends of the baffle 32 are fixedly connected with inserts 34; the inserts 34 are slidably arranged inside the arc grooves 33; a bolt is arranged on one side of the insert 34 away from the baffle 32, and the bolt penetrates through the arc groove 33; During operation, the baffles 32 are rotated so that the two baffles 32 close towards the middle of the air beam 24, and the baffles 32 drive the inserts 34 to slide along the arc grooves 33; when the two baffles 32 are adjusted to appropriate positions, the inserts 34 are locked and fixed with bolts; the air flow passing through the partition 31 and spraying downward in the air beam 24 is blocked and guided by the two baffles 32, so that the air flow converges towards the middle of the air beam 24, thereby reducing the situation of air flow diffusion, not only improving the blocking effect on water droplets, but also reducing the influence of the air flow on the water flow sprayed by the laser cutting heads 5.

[0029] As Figures 9 to 11 shown, rubber sealing sheets 35 are fixedly connected to both sides inside the air beam 24; the bottom of the rubber sealing sheets 35 is fixedly connected to the baffles 32; the connection part between the air beam 24 and the baffles 32 is shielded by the provided rubber sealing sheets 35, reducing the leakage of the air flow inside the air beam 24 from the connection part between the air beam 24 and the baffles 32.

[0030] Working principle: Rotate the baffle 32 so that the two side baffles 32 close towards the middle of the air beam 24, and the baffle 32 drives the insert 34 to slide along the arc groove 33; after the two side baffles 32 are adjusted to the appropriate positions, use bolts to lock and fix the insert 34; block and guide the air flow ejected downward through the partition 31 in the air beam 24 by the two side baffles 32, so that the air flow closes towards the middle of the air beam 24; the two electric push rods 30 on both sides push the two ends of the air beam 24 to rotate, so that the air beam 24 can be inclined, and the ejected air curtain can be inclined. The second motor 21 drives the second synchronous pulley 22 to rotate. Through the transmission of the second synchronous belt 23 and the second synchronous pulley 22, the lead screw 19 is driven to rotate, the slider 20 is driven to move along the sliding beam 18, the laser cutting head 5 is driven to move, and the distance between the two laser cutting heads 5 is controlled and adjusted. Place the workpiece to be processed on the operation board 2 of the machine table 1. The translation mechanism 3 moves, the translation mechanism 3 drives the support plate 4 to move, drives the disc 6 to move, drives the two laser cutting heads 5 to move, and moreover, makes one of the laser cutting heads 5 that first contacts the workpiece move along the set cutting line for cutting; at this time, the other laser cutting head 5 that later contacts the workpiece needs to adjust its position in time to ensure that the moving trajectories of the two laser cutting heads 5 are completely consistent with the set cutting line; therefore, the first motor 10 drives the first synchronous pulley 11 to rotate. Through the transmission of the first synchronous belt 12 and the first synchronous pulley 11, the first gear 9 is driven to rotate inside the C-shaped frame 7. The first gear 9 meshes with the external gear ring 8, so that the C-shaped frame 7 slides along the disc 6, and the C-shaped frame 7 drives a plurality of sliding seats 16 and rollers 17 to move along the circular guide groove 13; through the sliding fit of the rollers 17 and the circular guide groove 13, not only can the situation that the C-shaped frame 7 disengages from the outer ring of the disc 6 be avoided, but also the moving stability of the C-shaped frame 7 is improved, and the position of the laser cutting head 5 is controlled and adjusted; the two laser cutting heads 5 on both sides are adjusted by the two rotating mechanisms on both sides, so that the two laser cutting heads 5 can be kept on the same cutting line to perform cutting work on the workpiece, improving the cutting efficiency and accuracy. At the same time, the cutting of complex graphics of the workpiece can be completed. At the same time, when the laser cutting head 5 performs laser cutting, it will eject downward the water flow that guides the laser. When the water flow hits the workpiece, the water flow will generate splashing water droplets, and the splashing water flow will affect the normal operation of the other laser cutting head 5; therefore, when the two laser cutting heads 5 cut the workpiece, the air pump transports the air flow into the air beam 24 and then ejects it downward from the air beam 24 to form a downward flowing air curtain between the two laser cutting heads 5 to intercept the splashing water droplets and reduce the interference between the two laser cutting heads 5. By cutting the workpiece successively along the same cutting line by the two laser cutting heads 5, the time required for cutting the workpiece is effectively reduced, and the processing efficiency of the workpiece is improved.
