Description

Technical Field

[0001] The invention belongs to the technical field of laser plate cutting machines, and in particular relates to a laser plate cutting machine capable of automatically correcting deviation. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] During the cutting process of the laser cutting machine, the workpiece must first be placed on the workbench and clamped and locked by a locking device. After clamping, the laser cutting head must be operated to approach the workpiece to achieve positioning before laser cutting. The entire process requires at least two steps to operate, and the overall cutting efficiency is low.

[0004] At the same time, during the cutting process of the laser cutting machine, due to external force factors and vibration and other factors, the metal plate will cause a certain slight displacement. In the existing technology, when displacement occurs, the device needs to be stopped and the metal plate needs to be adjusted manually. The whole adjustment process is relatively cumbersome and dynamic adjustment during the processing process cannot be achieved, which urgently needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a laser plate cutting machine capable of automatically correcting deviation, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a laser plate cutting machine with automatic deviation correction comprises a frame, wherein conveying rollers are movably installed at equal distances inside the frame, and a conveying motor is built in the conveying rollers, and a bottom plate located below the conveying rollers is fixedly installed at the bottom end of the frame, a laser cutting assembly is arranged above the conveying rollers, an adjusting assembly is fixedly installed in the middle of the bottom end of the bottom plate, a linkage assembly is fixedly installed at the bottom end of the adjusting assembly, the left and right ends of the linkage assembly are connected with the laser cutting assembly, the left and right ends of the outer side surface of the conveying rollers are movably sleeved with clamping rings, the left and right sides of the top end of the linkage assembly are connected with the clamping ring, the left and right sides of the adjusting assembly near the bottom end are fixedly connected with infusion tubes, the inner side surfaces of the clamping rings near the top end are installed with pressure sensors, the top end of the clamping rings is fixedly installed with a deviation correction assembly, the end of the infusion tube away from the adjusting assembly is fixedly connected with a distribution valve, and the bottom end of the distribution valve is connected with the deviation correction assembly.

[0007] Among them, the conveying rollers can achieve self-rotation through built-in motors, and the metal plates are conveyed by multiple conveying rollers. Moreover, the device can be used in cooperation with external conveyor belt equipment, that is, the front and rear ends of the device respectively correspond to two conveyor belts for automatic loading and unloading of metal plates.

[0008] When cutting a metal plate, an external conveyor belt equipment can convey a metal plate to the position of the conveying rollers, and the conveying rollers drive the metal plate to move so that it is displaced below the laser cutting assembly.

[0009] As a further technical solution of the present invention, the laser cutting assembly includes a mounting frame. The bottom end of the mounting frame is connected to the linkage assembly, and electric adjusting rods are fixedly installed at the top ends of the mounting frame. The output ends of the electric adjusting rods are fixedly installed with top frames.

[0010] As a further technical solution of the present invention, the laser cutting assembly further includes a front and rear adjustment guide rail above the conveying rollers. The front and rear adjustment guide rail is connected to the top frame. A first lead screw is movably connected inside the front and rear adjustment guide rail. A left and right adjustment guide rail located below the front and rear adjustment guide rail is threadedly connected to the outer side of the first lead screw. The left and right adjustment guide rail moves back and forth relative to the front and rear adjustment guide rail. One end of the first lead screw is connected to an external motor.

[0011] As a further technical solution of the present invention, a second lead screw is movably connected inside the left and right adjustment guide rail. A laser head located below the second lead screw is threadedly connected to the outer side of the second lead screw. The laser head moves left and right relative to the left and right adjustment guide rail.

[0012] Before cutting the metal plate, it is necessary to adjust the length of the electric adjusting rod according to the size and cutting requirements of the metal plate to ensure that after the metal plate is clamped, the laser head can just correspond to the top end of the metal plate and perform the laser cutting process of the metal plate.

[0013] After the clamping of the metal plate and the positioning of the laser cutting assembly are completed, according to the cutting requirements, the external motor can be turned on to drive the left and right adjustment guide rail to move back and forth relative to the front and rear adjustment guide rail for adjusting the front and rear displacement of the cutting. Moreover, the external motor can be turned on to drive the laser head to move left and right relative to the left and right adjustment guide rail for adjusting the left and right position of the laser head, and the laser cutting process of the metal plate is completed through the laser head.

[0014] As a further technical solution of the present invention, the adjustment assembly includes an oil storage pipe. The bottom end of the oil storage pipe is connected to the linkage assembly. A pressure plate is movably sleeved inside the oil storage pipe. Hydraulic oil is filled between the bottom end of the pressure plate and the bottom end of the inner cavity of the oil storage pipe. Oil outlets are fixedly communicated with the left and right sides near the bottom end of the oil storage pipe.

[0015] As a further technical solution of the present invention, the oil outlet is communicated with the infusion tube. The adjusting assembly further includes an electric push rod. The top end of the electric push rod is connected to the bottom end of the bottom plate. The output end of the electric push rod penetrates through the top end of the oil storage tube and is connected to the pressure plate. The output end of the electric push rod is movably sleeved with a return spring. The upper and lower ends of the return spring are respectively connected to the top end of the inner cavity of the oil storage tube and the top end of the pressure plate.

[0016] In the initial state, the electric push rod is in the shortest state. At this time, the return spring is also in the initial state and has the shortest length. And at this time, the movable plate is also in the initial state, that is, at the highest point position. When it is necessary to clamp the metal plate, the electric push rod can be turned on to control its elongation. At this time, the pressure plate drops accordingly, and the return spring is stretched. At this time, the hydraulic oil located inside the oil storage tube can be pressurized and discharged through the oil outlets at both ends. And the electric push rod continues to elongate, and the return spring is in the limit stretched state, which can drive the whole oil storage tube to move downward, and finally apply a downward pressure to the movable plate.

[0017] As a further technical solution of the present invention, the linkage assembly includes a movable plate. The middle part of the top end of the movable plate is connected to the bottom end of the oil storage tube. The left and right ends of the movable plate are connected to the mounting frame. First fixed seats are fixedly connected to the positions near the four corners of the top end of the movable plate. One end of each first fixed seat away from the movable plate is movably connected to a connecting rod through a rotating shaft.

[0018] As a further technical solution of the present invention, one end of each connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft. The linkage assembly further includes linkage frames symmetrically arranged on the left and right. The bottom end of the linkage frame is connected to the second fixed seat. The top end of the second fixed seat is connected to the clamping ring.

[0019] When the movable plate moves downward under the push of the oil storage tube, it can synchronously drive the first fixed seat at the top end to move downward and drive the connecting rod to rotate. At this time, multiple connecting rods can swing towards the middle of the movable plate and apply a pulling force to the linkage frame at the top end. At this time, the two linkage frames can apply a pulling force to the two clamping rings at the top end and drive the two clamping rings to approach relatively. When the two clamping rings approach relatively, they can clamp the metal plate in the middle and complete the clamping and fixing process of the metal plate.

[0020] At the same time, when the movable plate moves downward, it can synchronously drive the mounting frame to move downward. At this time, the top frame at the top end and the front-back adjustment guide rail and the left-right adjustment guide rail drop accordingly, and finally drive the laser head to drop. At this time, the laser head can automatically drop to the top of the metal plate and complete the positioning, completing the clamping and cutting positioning of the metal plate.

[0021] By utilizing the coordination between the adjustment component and the linkage component, as well as the functions of the clamping ring and the laser cutting component, it is only necessary to control the electric push rod to quickly clamp the side of the metal plate and complete the positioning process before cutting. The entire process can be completed quickly without the need for separate steps, that is, the clamping of the metal plate and the cutting positioning are completed at the same time, which significantly shortens the preparation time before cutting and improves the overall cutting efficiency.

[0022] When the cutting of the metal plate is completed, the electric push rod can be directly controlled to shorten or reset. At this time, negative pressure can be generated inside the oil storage pipe, and the hydraulic oil can flow back to the inside of the oil storage pipe. The reset spring is automatically reset, and the oil storage pipe automatically rises, and finally drives the movable plate to rise. At this time, the laser cutting assembly rises and releases the cutting positioning state. At the same time, the two linkage frames move away from each other, and drive the two clamping rings to move away from each other, releasing the clamping positioning process of the metal plate, and the conveying of the conveyor roller is automatically completed to complete the discharge of the metal plate.

[0023] By utilizing the automatic resetting process of the device and coordinating with the conveying of the conveying roller, the device can automatically release the limiting fixation and cutting positioning state of the metal plate when it returns to its initial state, and automatically complete the discharge of the metal plate after cutting. The whole process is completed automatically without manual operation, and the subsequent metal plate cutting process can be carried out quickly to complete continuous processing, further improving the overall processing efficiency.

[0024] As a further technical solution of the present invention, the correction component includes a temporary storage tube, which is connected to the top of the clamp ring, and the end of the temporary storage tube away from the middle of the conveying roller is fixedly connected with a bent pipe, and the top of the bent pipe is connected to the bottom end of the distribution valve, and the interior of the temporary storage tube is movably sleeved with a piston plate, and the piston plate is displaced left and right relative to the temporary storage tube.

[0025] As a further technical solution of the present invention, one end of the piston plate close to the middle of the conveying roller is fixedly connected to a push rod located inside the temporary storage tube, and the end of the push rod away from the piston plate passes through one end of the temporary storage tube. A return spring is movably sleeved on the outer side of the push rod, and the left and right ends of the return spring are respectively connected to one end of the piston plate and one end of the inner cavity of the temporary storage tube. When the return spring is in an initial state, the end of the push rod away from the piston plate and the pressure sensor are on the same horizontal plane.

[0026] After the clamping is completed, the hydraulic oil discharged through the oil delivery port enters the interior of the infusion pipe, and is transported through the infusion pipe into the interior of the distribution valve to wait for distribution;

[0027] After the clamping of the metal plate is completed, the side of the metal plate can be in contact with multiple pressure sensors and also with multiple push rods at this time. When the metal plate is in the normal position without tilting, the distances between the metal plate and the multiple pressure sensors are the same and the pressure values on them are also the same, that is, the pressure values of the multiple pressure sensors are approximately the same and within a predetermined error range;

[0028] If the difference in the value of a single pressure sensor is less than the values of the other pressure sensors and exceeds the threshold range, and the value of the pressure sensor on the opposite side is greater than the values of the other pressure sensors and exceeds the threshold range, it means that the metal plate is tilted towards the opposite side. At this time, the valve inside the bent pipe on the opposite side is opened accordingly, and the hydraulic oil inside the distribution valve enters the inside of the temporary storage pipe, and pushes the piston plate and the push rod to displace towards the opposite side. At this time, the metal plate can be pushed to displace towards the opposite side until the pressure difference measured by the two oppositely arranged pressure sensors is within the set threshold range, and then the valve of the bent pipe on the opposite side can be closed to complete the automatic correction process.

[0029] By utilizing the hydraulic oil derived during the clamping of the metal plate and introducing it into the inside of the distribution valve for temporary storage, and at the same time cooperating with the pressure values of multiple pressure sensors to detect whether the metal plate at the corresponding position is tilted, and then starting the corresponding correction component to complete the correction process. The whole process can be automatically completed, which can effectively adjust the small offsets during the laser cutting process of the metal plate, without the need to stop the machine for operation, and can realize the dynamic adjustment during the cutting process, significantly improving the cutting quality.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. By utilizing the cooperation between the adjustment component and the linkage component, and the functions of the clamping ring and the laser cutting component, the present invention can quickly realize the side clamping of the metal plate only by controlling the electric push rod, and at the same time complete the positioning process before cutting. The whole process is completed quickly without being carried out in steps, that is, the clamping and cutting positioning of the metal plate are completed at the same time, significantly shortening the preparation time before cutting and improving the overall cutting efficiency.

[0032] 2. By utilizing the hydraulic oil derived during the clamping of the metal plate and introducing it into the inside of the distribution valve for temporary storage, and at the same time cooperating with the pressure values of multiple pressure sensors to detect whether the metal plate at the corresponding position is tilted, and then starting the corresponding correction component to complete the correction process. The whole process can be automatically completed, which can effectively adjust the small offsets during the laser cutting process of the metal plate, without the need to stop the machine for operation, and can realize the dynamic adjustment during the cutting process, significantly improving the cutting quality.

[0033] 3. By utilizing the automatic reset process of the device and coordinating with the conveyance of the conveying rollers, when the device returns to its initial state, it can automatically release the limit fixation and cutting positioning state of the metal plate, and automatically complete the discharging of the metal plate after cutting. The entire process is automatically completed without manual operation, enabling the subsequent cutting process of the metal plate to be carried out quickly and achieving continuous processing, thereby further improving the overall processing efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] As Figures 1 to 9 shown, in the embodiment of the present invention, an automatically rectifiable laser cutting machine for plates includes a frame 1. Inside the frame 1, conveying rollers 2 are movably installed at equal intervals. A conveying motor is built in the conveying rollers 2. A bottom plate 3 located below the conveying rollers 2 is fixedly installed at the bottom end of the frame 1. A laser cutting assembly 4 is provided above the conveying rollers 2. A regulating assembly 5 is fixedly installed in the middle of the bottom end of the bottom plate 3. A linkage assembly 6 is fixedly installed at the bottom end of the regulating assembly 5. The left and right ends of the linkage assembly 6 are connected to the laser cutting assembly 4. Clamping rings 8 are movably sleeved on the left and right ends of the outer side of the conveying rollers 2. The left and right sides of the top end of the linkage assembly 6 are connected to the clamping rings 8. Liquid infusion pipes 10 are fixedly communicated with the left and right sides near the bottom end of the regulating assembly 5. Pressure sensors 9 are installed on the inner sides near the top ends of the clamping rings 8. Rectifying assemblies 7 are fixedly installed at the top ends of the clamping rings 8. The ends of the liquid infusion pipes 10 far away from the regulating assembly 5 are fixedly communicated with distribution valves 11. The bottom ends of the distribution valves 11 are communicated with the rectifying assemblies 7.

[0046] Among them, the conveying rollers 2 can achieve self-rotation through the built-in motor, and metal plates are conveyed through a plurality of conveying rollers 2. Moreover, the device can be used in cooperation with external conveyor belt equipment, that is, the front and rear ends of the device respectively correspond to two conveyor belts for automatic loading and unloading of metal plates;

[0047] When cutting a metal plate, a metal plate can be conveyed to the conveying rollers 2 through external conveyor belt equipment, and the conveying rollers 2 drive the metal plate to move so that it is displaced below the laser cutting assembly 4.

[0048] As Figure 1 and Figure 2 as well as Figure 3As shown in the figure, the laser cutting assembly 4 includes a mounting frame 401. The bottom end of the mounting frame 401 is connected to the linkage assembly 6. Electric adjusting rods 402 are fixedly installed at the top ends of the mounting frame 401. Top frames 403 are fixedly installed at the output ends of the electric adjusting rods 402. The laser cutting assembly 4 further includes a front-back adjusting guide rail 404 located above the conveying rollers 2. The front-back adjusting guide rail 404 is connected to the top frame 403. A first lead screw 405 is movably connected inside the front-back adjusting guide rail 404. A left-right adjusting guide rail 406 located below the front-back adjusting guide rail 404 is threadedly connected to the outer side of the first lead screw 405. The left-right adjusting guide rail 406 moves back and forth relative to the front-back adjusting guide rail 404. One end of the first lead screw 405 is connected to an external motor. A second lead screw 407 is movably connected inside the left-right adjusting guide rail 406. A laser head 408 located below the second lead screw 407 is threadedly connected to the outer side of the second lead screw 407. The laser head 408 moves left and right relative to the left-right adjusting guide rail 406.

[0049] Before cutting the metal plate, it is necessary to adjust the length of the electric adjusting rod 402 according to the size and cutting requirements of the metal plate to ensure that after the metal plate is clamped, the laser head 408 can just correspond to the top end of the metal plate and the laser cutting process of the metal plate can be carried out.

[0050] After the metal plate is clamped and the laser cutting assembly 4 is positioned, according to the cutting requirements, the external motor can be turned on to drive the left-right adjusting guide rail 406 to move back and forth relative to the front-back adjusting guide rail 404 for adjusting the front-back displacement of the cutting, and the external motor can be turned on to drive the laser head 408 to move left and right relative to the left-right adjusting guide rail 406 for adjusting the left and right positions of the laser head 408, and the laser cutting process of the metal plate can be completed by the laser head 408.

[0051] As Figure 2 and Figure 6 and Figure 7 As shown in the figure, the adjusting assembly 5 includes an oil storage pipe 501. The bottom end of the oil storage pipe 501 is connected to the linkage assembly 6. A pressure plate 502 is movably sleeved inside the oil storage pipe 501. Hydraulic oil is filled between the bottom end of the pressure plate 502 and the bottom end of the inner cavity of the oil storage pipe 501. Oil outlets 504 are fixedly communicated with both the left and right sides of the oil storage pipe 501 near the bottom end. The oil outlets 504 are communicated with the infusion pipes 10. The adjusting assembly 5 further includes an electric push rod 503. The top end of the electric push rod 503 is connected to the bottom end of the bottom plate 3. The output end of the electric push rod 503 penetrates through the top end of the oil storage pipe 501 and is connected to the pressure plate 502. A return spring 505 is movably sleeved on the output end of the electric push rod 503. The upper and lower ends of the return spring 505 are respectively connected to the top end of the inner cavity of the oil storage pipe 501 and the top end of the pressure plate 502.

[0052] In the initial state, the electric push rod 503 is in the shortest state. At this time, the return spring 505 is also in the initial state and has the shortest length. At this time, the movable plate 601 is also in the initial state, that is, at the highest point position. When it is necessary to clamp the metal plate, the electric push rod 503 can be turned on to control its elongation. At this time, the pressure plate 502 will drop accordingly, and the return spring 505 will be stretched. At this time, the hydraulic oil inside the oil storage pipe 501 can be pressurized and discharged through the oil delivery ports 504 at both ends. And the electric push rod 503 continues to elongate, and the return spring 505 is in the extreme stretching state, which can drive the entire oil storage pipe 501 to move downward, and finally apply a downward pressure on the movable plate 601.

[0053] As Figure 2 and Figure 5 as well as Figure 6 shown, the linkage assembly 6 includes a movable plate 601. The middle of the top end of the movable plate 601 is connected to the bottom end of the oil storage pipe 501. The left and right ends of the movable plate 601 are connected to the mounting frame 401. At the positions near the four corners of the top end of the movable plate 601, first fixing seats 602 are fixedly connected. One end of each first fixing seat 602 away from the movable plate 601 is movably connected to a connecting rod 604 through a rotating shaft. One end of each connecting rod 604 away from the first fixing seat 602 is movably connected to a second fixing seat 603 through a rotating shaft. The linkage assembly 6 also includes linkage frames 605 arranged symmetrically on the left and right. The bottom end of the linkage frame 605 is connected to the second fixing seat 603. The top end of the second fixing seat 603 is connected to the clamping ring 8.

[0054] Embodiment: When the movable plate 601 moves downward under the push of the oil storage pipe 501, it can synchronously drive the first fixing seat 602 at the top end to move downward, and drive the connecting rod 604 to rotate. At this time, multiple connecting rods 604 can swing towards the middle of the movable plate 601, and apply a pulling force on the linkage frame 605 at the top end. At this time, the two linkage frames 605 can apply a pulling force on the two clamping rings 8 at the top end, and drive the two clamping rings 8 to approach each other relatively. When the two clamping rings 8 approach each other relatively, they can clamp the metal plate in the middle, completing the clamping and fixing process of the metal plate;

[0055] At the same time, when the movable plate 601 moves downward, it can synchronously drive the mounting frame 401 to move downward. At this time, the top frame 403, the front and rear adjustment guide rails 404 and the left and right adjustment guide rails 406 at the top end will drop accordingly, and finally drive the laser head 408 to drop. At this time, the laser head 408 can automatically drop to the top of the metal plate and complete the positioning, completing the positioning of the clamping and cutting of the metal plate.

[0056] By utilizing the cooperation between the adjustment component 5 and the linkage component 6, as well as the functions of the clamping ring 8 and the laser cutting component 4, it is only necessary to control the electric push rod 503 to quickly clamp the side of the metal plate and complete the positioning process before cutting. The entire process can be completed quickly without the need for separate steps, that is, the clamping of the metal plate and the cutting positioning are completed at the same time, which significantly shortens the preparation time before cutting and improves the overall cutting efficiency.

[0057] When the cutting of the metal plate is completed, the electric push rod 503 can be directly controlled to shorten or reset. At this time, negative pressure can be generated inside the oil storage pipe 501, and the hydraulic oil can flow back to the inside of the oil storage pipe 501. The reset spring 505 is automatically reset, and the oil storage pipe 501 automatically rises, and finally drives the movable plate 601 to rise. At this time, the laser cutting component 4 rises accordingly to release the cutting positioning state. At the same time, the two linkage frames 605 are relatively separated, and drive the two clamping rings 8 to be relatively separated, releasing the clamping positioning process of the metal plate, and cooperating with the conveying of the conveying roller 2 to automatically complete the discharge of the metal plate.

[0058] By utilizing the automatic resetting process of the device and coordinating the conveying of the conveying roller 2, the device can automatically release the limiting fixation and cutting positioning state of the metal plate when it returns to its initial state, and automatically complete the discharge of the metal plate after cutting. The entire process is completed automatically without manual operation, and the subsequent metal plate cutting process can be carried out quickly to complete continuous processing, further improving the overall processing efficiency.

[0059] like Figure 2 and Figure 5 as well as Figure 8 and Figure 9 As shown, the deviation correction component 7 includes a temporary storage tube 701, which is connected to the top end of the clamp ring 8, and the end of the temporary storage tube 701 away from the middle of the conveying roller 2 is fixedly connected with a bent tube 705, the top of the bent tube 705 is connected to the bottom end of the distribution valve 11, and the interior of the temporary storage tube 701 is movably sleeved with a piston plate 702, and the piston plate 702 is displaced left and right relative to the temporary storage tube 701. The end of the piston plate 702 close to the middle of the conveying roller 2 is fixedly connected with a push rod 703 located inside the temporary storage tube 701, and the end of the push rod 703 away from the piston plate 702 passes through one end of the temporary storage tube 701, and the outer side surface of the push rod 703 is movably sleeved with a reset spring 704, and the left and right ends of the reset spring 704 are respectively connected to one end of the piston plate 702 and one end of the inner cavity of the temporary storage tube 701. When the reset spring 704 is in the initial state, the end of the push rod 703 away from the piston plate 702 and the pressure sensor 9 are on the same horizontal plane.

[0060] Embodiment: The pressure sensor 9 adopts the MS5803-14BA micro pressure sensor, wherein the threshold range of the pressure sensor 9 is 0.2 Pa, and the allowed error range is 0.2±0.05 Pa.

[0061] After the clamping is completed, the hydraulic oil exported through the oil outlet 504 then enters the interior of the infusion tube 10 and is transported through the infusion tube 10 into the interior of the distribution valve 11 to await distribution;

[0062] After the clamping of the metal plate is completed, the side of the metal plate can then contact a plurality of pressure sensors 9 and also contact a plurality of push rods 703. When the metal plate is in the normal position without tilting, the distance between the metal plate and the plurality of pressure sensors 9 is the same and the pressure values on them are also the same, that is, the pressure values of the plurality of pressure sensors 9 are approximately the same and within a predetermined error range;

[0063] If the difference in the value of a single pressure sensor 9 is less than the values of the remaining pressure sensors 9 and exceeds the threshold range, and the value of the pressure sensor 9 on the opposite side is greater than the values of the remaining pressure sensors 9 and exceeds the threshold range, it means that the metal plate is tilted towards the opposite side. At this time, the valve inside the bent tube 705 on the opposite side is opened, and the hydraulic oil inside the distribution valve 11 then enters the interior of the temporary storage tube 701 and pushes the piston plate 702 and the push rod 703 to displace towards the opposite side. At this time, the metal plate can be pushed to displace towards the opposite side until the pressure difference measured by two relatively arranged pressure sensors 9 is within the set threshold range, and then the valve of the bent tube 705 on the opposite side can be closed to complete the automatic correction process.

[0064] By utilizing the hydraulic oil exported during the clamping of the metal plate and introducing it into the interior of the distribution valve 11 for temporary storage, and at the same time cooperating with the pressure values of a plurality of pressure sensors 9 to detect whether the metal plate at the corresponding point is tilted, and then starting the corresponding correction assembly 7 to complete the correction process. The entire process can be automatically completed, effectively adjusting the small offsets during the laser cutting process of the metal plate, without the need to stop the machine for operation, enabling dynamic adjustment during the cutting process, and significantly improving the cutting quality.

[0065] Working principle and usage process:

[0066] Before cutting the metal plate, it is necessary to adjust the length of the electric adjusting rod 402 according to the size and cutting requirements of the metal plate to ensure that after the clamping of the metal plate is completed, the laser head 408 can just correspond to the top of the metal plate and carry out the laser cutting process of the metal plate;

[0067] When cutting the metal plate, an external conveyor belt device can be used to convey a metal plate to the conveying roller 2, and the conveying roller 2 drives the metal plate to move so that it is displaced below the laser cutting assembly 4;

[0068] In the initial state, the electric push rod 503 is in the shortest state. At this time, the return spring 505 is also in the initial state and has the shortest length. Also at this time, the movable plate 601 is in the initial state, that is, at the highest point position. When it is necessary to clamp the metal plate, the electric push rod 503 can be turned on to control its elongation. At this time, the pressure plate 502 drops accordingly, and the return spring 505 is stretched. At this time, the hydraulic oil inside the oil storage pipe 501 can be pressurized and discharged through the oil delivery ports 504 at both ends. And the electric push rod 503 continues to elongate, and the return spring 505 is in the extreme stretched state, which can drive the entire oil storage pipe 501 to move downward, and finally apply a downward pressure on the movable plate 601;

[0069] When the movable plate 601 moves downward under the push of the oil storage pipe 501, it can synchronously drive the first fixed seat 602 at the top to move downward, and the drive link 604 rotates. At this time, multiple links 604 can swing towards the middle of the movable plate 601 and apply a pulling force on the linkage frame 605 at the top. At this time, the two linkage frames 605 can apply a pulling force on the two clamping rings 8 at the top and drive the two clamping rings 8 to approach each other relatively. When the two clamping rings 8 approach each other relatively, they can clamp the metal plate in the middle and complete the clamping and fixing process of the metal plate;

[0070] At the same time, when the movable plate 601 moves downward, it can synchronously drive the mounting frame 401 to move downward. At this time, the top frame 403, the front and rear adjustment guide rails 404, and the left and right adjustment guide rails 406 at the top drop accordingly, and finally drive the laser head 408 to drop. At this time, the laser head 408 can automatically drop to the top of the metal plate and complete the positioning, completing the positioning of the clamping and cutting of the metal plate;

[0071] After the clamping is completed, the hydraulic oil exported through the oil delivery port 504 then enters the interior of the infusion pipe 10 and is transported through the infusion pipe 10 and enters the interior of the distribution valve 11 to wait for distribution;

[0072] When the clamping of the metal plate is completed, the side of the metal plate can contact multiple pressure sensors 9 and also contact multiple push rods 703. When the metal plate is in the normal position and does not tilt, at this time, the distances between the metal plate and the multiple pressure sensors 9 are the same and the pressure values on them are also the same, that is, the pressure values of the multiple pressure sensors 9 are roughly the same and within a predetermined error range;

[0073] If the difference in the value of a single pressure sensor 9 is smaller than the values ​​of the other pressure sensors 9 and exceeds the threshold range, and the value of the opposite side pressure sensor 9 is larger than the values ​​of the other pressure sensors 9 and exceeds the threshold range, it means that the metal plate is tilted toward the opposite side. At this time, the valve inside the opposite side bend 705 is opened, and the hydraulic oil inside the distribution valve 11 enters the interior of the temporary storage tube 701 and pushes the piston plate 702 and the push rod 703 to move toward the opposite side. At this time, the metal plate can be pushed to move toward the opposite side until the pressure difference measured by the two relatively arranged pressure sensors 9 is within the set threshold range, and then the valve of the opposite side bend 705 can be closed to complete the automatic deviation correction process;

[0074] After the clamping of the metal plate and the positioning of the laser cutting assembly 4 are completed, the external motor can be turned on according to the cutting requirements to drive the left and right adjustment rails 406 to move forward and backward relative to the front and rear adjustment rails 404, so as to adjust the front and rear displacement of the cutting, and the external motor can be turned on to drive the laser head 408 to move left and right relative to the left and right adjustment rails 406, so as to adjust the left and right position of the laser head 408, and complete the laser cutting process of the metal plate through the laser head 408;

[0075] When the cutting of the metal plate is completed, the electric push rod 503 can be directly controlled to shorten or reset. At this time, negative pressure can be generated inside the oil storage pipe 501, and the hydraulic oil can flow back to the inside of the oil storage pipe 501. The reset spring 505 is automatically reset, and the oil storage pipe 501 automatically rises, and finally drives the movable plate 601 to rise. At this time, the laser cutting component 4 rises accordingly to release the cutting positioning state. At the same time, the two linkage frames 605 are relatively separated, and drive the two clamping rings 8 to be relatively separated, releasing the clamping positioning process of the metal plate, and cooperating with the conveying of the conveying roller 2 to automatically complete the discharge of the metal plate.
