Detailed implementation manners

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some, but not all, of the embodiments of the present invention. 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.

[0035] The embodiments of the present invention provide a laser cutting device for metal sheet processing, including a processing platform 1. Exemplarily, such as Figure 1 and Figure 2As shown, two groups of supporting vertical plates 2 are symmetrically arranged at the edges on both sides of the top of the processing platform 1; a first electric sliding table 3 is arranged at the top of the two groups of supporting vertical plates 2; a moving seat 4 is drivingly connected to the output end of the first electric sliding table 3; a second electric sliding table 5 is arranged at the bottom of the moving seat 4; a first electric push rod 6 is drivingly connected to the output end of the second electric sliding table 5; the first electric sliding table 3, the moving seat 4, the second electric sliding table 5 and the first electric push rod 6 are combined to form a laser moving mechanism; a self-adjusting connecting mechanism 7 is drivingly connected to the output end of the first electric push rod 6; a laser generator 8 is installed at the center of the bottom of the self-adjusting connecting mechanism 7; two groups of plate limiting mechanisms 9 are symmetrically arranged on the opposite side walls of the two groups of supporting vertical plates 2; a slag collecting groove 10 is opened at the top of the processing platform 1; a telescopic groove 12 is opened at the bottom of the slag collecting groove 10; a plate supporting mechanism 11 movably penetrates through the telescopic groove 12; several groups of second electric push rods 13 are arranged on the bottom inner wall of the telescopic groove 12; the several groups of second electric push rods 13 are drivingly connected to the plate supporting mechanism 11; a dust suction pump 14 is arranged in the processing platform 1; the output end of the dust suction pump 14 is communicated with the telescopic groove 12; a storage groove 15 is opened at the bottom of the processing platform 1; a support plate 16 is slidably connected in the storage groove 15 in the vertical direction; several groups of universal wheels 17 are arranged at the bottom edge of the support plate 16; a third electric push rod 18 is arranged at the center of the top inner wall of the storage groove 15; the output end of the third electric push rod 18 is drivingly connected to the support plate 16.

[0036] Before using the laser cutting device, the third electric push rod 18 can be controlled to drive the support plate 16 to descend, so that several groups of universal wheels 17 are in contact with the ground and the processing platform 1 is lifted. At this time, the laser cutting device can be moved to the corresponding position, and then several groups of universal wheels 17 are controlled to be retracted into the storage groove 15 again, so that the processing platform 1 is in contact with the ground again, thereby enabling the laser cutting device to remain stable when processing metal plates and improving the use convenience of the laser cutting device. When performing the processing work of metal plates, first place the metal plate on the top of the plate supporting mechanism 11, and then control the two groups of plate limiting mechanisms 9 to fix the metal plate from both sides. After the metal plate is fixed, control the laser moving mechanism to drive the laser generator 8 to move through the self-adjusting connecting mechanism 7, so that the laser generator 8 can perform cutting processing on the metal plate after being started.

[0037] Exemplarily, such as Figure 3 and Figure 4As shown, the self-adjusting connection mechanism 7 includes a housing 701; four first sliding grooves 702 are arranged at the bottom of the housing 701 in an annular array; a fourth electric push rod 703 is arranged in each first sliding groove 702; a universal ball 704 is drivingly connected to the output end of each fourth electric push rod 703; a magnetic limit plate 705 is hinged to one end of each universal ball 704 away from the corresponding fourth electric push rod 703; several laser ranging modules 706 are arranged at the bottom of the housing 701 in an annular array; an adjustment cavity 708 is arranged inside the housing 701; two lead screws 709 are arranged in the adjustment cavity 708; one end of the two lead screws 709 is fixedly connected, and the other ends are respectively rotatably connected to the inner walls on both sides of the adjustment cavity 708; the thread directions of the two lead screws 709 are opposite, and the central axes are on the same straight line; two sliding connection blocks 710 are slidably connected to the top inner wall of the adjustment cavity 708; a second sliding groove 711 is opened at the bottom of each sliding connection block 710; the top of each fourth electric push rod 703 is slidably connected in the corresponding second sliding groove 711; a motor 707 is arranged on one side wall of the housing 701; the output end of the motor 707 is drivingly connected to one of the lead screws 709.

[0038] An annular groove is opened on the outer wall of the laser generator 8, and a metal ring is arranged in the annular groove. When installing the laser generator 8, place the laser generator 8 at the center of the bottom of the housing 701, and then control the motor 707 to drive the two lead screws 709 to rotate. Under the threaded connection relationship between the two lead screws 709 and the two sliding connection blocks 710, the two sliding connection blocks 710 move towards the opposite sides. Since the four fourth electric push rods 703 are respectively slidably connected in the two second sliding grooves 711, the four fourth electric push rods 703 can drive the four magnetic limit plates 705 to move towards the groove of the laser generator 8 through the four universal balls 704. When approaching the groove, the four magnetic limit plates 705 will rotate towards the groove under the magnetic action with the metal ring. When the four magnetic limit plates 705 enter the groove, the fixation of the laser generator 8 is completed. This not only enables the laser generator 8 to be quickly disassembled when a failure occurs and needs to be repaired, but also can monitor the unevenness of the plate in the laser cutting path in real time through several laser ranging modules 706 arranged in an annular array, and then separately control the several fourth electric push rods 703 to adjust the angle of the laser generator 8, so that the edge of the cut metal plate is more neat after leveling, which not only improves the maintenance efficiency of the laser cutting device, but also improves the working quality of the laser cutting device.

[0039] Exemplarily, such as Figure 5As shown, the sheet limiting mechanism 9 includes a spacing adjustment module 901; two groups of fifth electric push rods 902 are symmetrically and drivingly connected to the output end of the spacing adjustment module 901; two groups of clamping modules 903 are symmetrically and drivingly connected to the output ends of the two groups of fifth electric push rods 902; two groups of clamping plates 904 are drivingly connected to the output end of each group of clamping modules 903; a number of groups of pressure rollers 905 are symmetrically and equidistantly arranged on the opposite side walls of the two groups of clamping plates 904; two groups of sixth electric push rods 906 are symmetrically arranged on the opposite side walls of the two groups of clamping plates 904; the output end of each group of sixth electric push rods 906 passes through a corresponding clamping plate 904 and is drivingly connected to a brake pad 907.

[0040] When fixing the metal sheet, first control the two groups of spacing adjustment modules 901 to drive the four groups of fifth electric push rods 902 to adjust the spacing according to the size of the metal sheet, then control the four groups of fifth electric push rods 902 to drive the four groups of clamping modules 903 to move towards the edges of the sheet, then control the four groups of clamping modules 903 to drive the four groups of clamping plates 904 to clamp the two side edges of the metal sheet, so that a number of groups of pressure rollers 905 are in contact with the top and bottom of the metal sheet, and then control the eight groups of sixth electric push rods 906 to drive the eight groups of brake pads 907 to contact the top and bottom of the metal sheet to fix it. When the clamping part coincides with the cutting part, the corresponding brake pads 907 can be controlled to disengage from the metal sheet while a number of groups of pressure rollers 905 continue to support the metal sheet, and then control the two groups of clamping modules 903 to move horizontally to expose the cutting part. This not only can fix metal sheets of any size, improving the working compatibility of the laser cutting device, but also avoids the need to adjust the position of the metal sheet due to the appearance of cutting blind spots, improving the working efficiency of the laser cutting device.

[0041] Exemplarily, as Figure 6 and Figure 7 As shown, the sheet support mechanism 11 includes a support block 1101; a number of groups of support frame plates 1102 are sequentially sleeved on the outer wall of the support block 1101; a number of groups of first communication holes 1103 are evenly distributed on the outer wall of each group of support frame plates 1102; a second dust suction cavity 1106 is provided in each group of support frame plates 1102; each second dust suction cavity 1106 is communicated with the corresponding number of groups of first communication holes 1103; each second dust suction cavity 1106 is communicated with the telescopic groove 12; a first dust suction cavity 1105 is provided in the support block 1101; the first dust suction cavity 1105 is communicated with the telescopic groove 12; a number of groups of second communication holes 1104 are evenly distributed on the four inner walls of the first dust suction cavity 1105.

[0042] When performing laser cutting on technical plates, several groups of support frame plates 1102 can be controlled to contract into the telescopic grooves 12 according to the size of the metal plate, so that the edge of the metal plate is suspended, facilitating laser cutting. At the same time, no matter what size the plate support mechanism 11 is adjusted to, several groups of corresponding first communication holes 1103 are always exposed on the outermost side. When the slag generated by laser cutting the metal plate falls, the suction pump of the second dust suction cavity 1106 will suck the slag into the telescopic groove 12 through the corresponding second dust suction cavity 1106 and several groups of first communication holes 1103 for collection and storage. This not only enables the support effect on the metal plate to achieve suspended cutting, avoiding damage to the support part by the laser, but also can timely suck and collect the slag, improving the use effect of the laser cutting device.

[0043] By controlling the four magnetic limit plates 705 to move towards the grooves of the laser generator 8, when approaching the grooves, the four magnetic limit plates 705 will rotate towards the grooves under the magnetic action. When the four magnetic limit plates 705 enter the grooves, the fixation of the laser generator 8 is completed. This not only enables the laser generator 8 to be quickly disassembled when a fault occurs and needs to be repaired, but also can separately control several groups of fourth electric push rods 703 to adjust the angle of the laser generator 8, making the edge of the cut metal plate neater after leveling, not only improving the repair efficiency of the laser cutting device, but also improving the working quality of the laser cutting device.

[0044] By controlling several groups of support frame plates 1102 to contract into the telescopic grooves 12, the edge of the metal plate is suspended. No matter what size the plate support mechanism 11 is adjusted to, several groups of corresponding first communication holes 1103 are always exposed on the outermost side. When the slag generated by laser cutting the metal plate falls, the suction pump of the second dust suction cavity 1106 will suck the slag into the telescopic groove 12 through the corresponding second dust suction cavity 1106 and several groups of first communication holes 1103 for collection and storage. This not only enables the support effect on the metal plate to achieve suspended cutting, avoiding damage to the support part by the laser, but also can timely suck and collect the slag, improving the use effect of the laser cutting device.

[0045] By controlling several groups of pressure rollers 905 to abut against the top and bottom of the metal plate, and then controlling eight brake pads 907 to abut against the top and bottom of the metal plate to fix it. When the clamping part coincides with the cutting part, the corresponding brake pads 907 can be controlled to disengage from the metal plate while several groups of pressure rollers 905 continue to support the metal plate, and then control the two clamping modules 903 to move horizontally to expose the cutting part. This not only can fix metal plates of any size, improving the working compatibility of the laser cutting device, but also avoids the need to adjust the position of the metal plate due to the appearance of a cutting blind area, improving the working efficiency of the laser cutting device.

[0046] By controlling the third electric push rod 18 to drive the support plate 16 to descend, a plurality of sets of universal wheels 17 are made to contact the ground and lift the processing platform 1. At this time, the laser cutting device can be moved to the corresponding position, and then the plurality of sets of universal wheels 17 are controlled to be retracted into the receiving groove 15 again, so that the processing platform 1 contacts the ground again, thereby enabling the laser cutting device to remain stable when processing metal sheets and improving the usability of the laser cutting device.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
