Obviously, the described embodiments are 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.

[0024] The embodiment of the present invention provides a laser cutting device for metal sheet processing, comprising a processing platform 1.

[0025] Before the laser cutting device is used, 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 re-stored into the storage groove 15, so that the processing platform 1 is in contact with the ground again, so that the laser cutting device can remain stable when processing the metal sheet, and the convenience of using the laser cutting device is improved. When processing the metal sheet, first place the metal sheet on the top of the sheet support mechanism 11, and then control the two groups of sheet limit mechanisms 9 to fix the metal sheet from both sides. After the metal sheet is fixed, control the laser moving mechanism to drive the laser generator 8 to move through the self-adjusting connection mechanism 7, so that the laser generator 8 can cut the metal sheet after starting.

[0026] For example, Figure 3 and Figure 4As shown, the self-adjusting connection mechanism 7 includes a shell 701; four groups of first slide grooves 702 are distributed in a circular array at the bottom of the shell 701; a group of fourth electric push rods 703 are arranged in each group of the first slide grooves 702; a group of universal balls 704 are transmission-connected to the output end of each group of the fourth electric push rods 703; a group of magnetic limit plates 705 are hinged at one end of each group of universal balls 704 away from the corresponding group of fourth electric push rods 703; a plurality of groups of laser ranging modules 706 are distributed in a circular array at the bottom of the shell 701; an adjusting cavity 708 is arranged in the shell 701; two groups of Screw rod 709; one end of the two groups of screw rods 709 are fixedly connected, and the other ends are rotatably connected to the inner walls on both sides of the adjustment chamber 708; the thread directions of the two groups of screw rods 709 are opposite, and the central axes are on the same straight line; two groups of sliding connection blocks 710 are slidably connected on the top inner wall of the adjustment chamber 708; a group of second slide grooves 711 are opened at the bottom of each group of sliding connection blocks 710; the top of each group of the fourth electric push rods 703 is slidably connected in a corresponding group of second slide grooves 711; a motor 707 is provided on one side wall of the shell 701; the output end of the motor 707 is transmission-connected to one of the groups of screw rods 709.

[0027] An annular groove is provided on the outer wall of the laser generator 8, and a metal ring is provided in the annular groove. When installing the laser generator 8, the laser generator 8 is placed at the bottom center of the shell 701, and then the motor 707 is controlled to drive the two sets of screw rods 709 to rotate. Under the threaded connection relationship between the two sets of screw rods 709 and the two sets of sliding connection blocks 710, the two sets of sliding connection blocks 710 move toward the opposite side. Since the four sets of fourth electric push rods 703 are respectively slidably connected in the two sets of second slide grooves 711, the four sets of fourth electric push rods 703 can drive the four sets of magnetic limit plates 705 to move toward the groove of the laser generator 8 through the four sets of universal balls 704. When the four sets of fourth electric push rods 703 are close to the groove, the four sets of magnetic limit plates 705 are moved to the groove of the laser generator 8. When the laser generator 8 is fixed, the four groups of magnetic limit plates 705 will rotate toward the groove under the magnetic effect of the metal ring. When the four groups of magnetic limit plates 705 enter the groove, the laser generator 8 is fixed. Not only can the laser generator 8 be quickly disassembled when it fails and needs maintenance, but also the laser ranging modules 706 distributed in a circular array can monitor the convexity and concavity of the plate in the laser cutting path in real time, and then control several groups of fourth electric push rods 703 separately to adjust the angle of the laser generator 8, so that the edge of the cut metal plate is more neat after the leveling work, which not only improves the maintenance efficiency of the laser cutting device, but also improves the working quality of the laser cutting device.

[0028] For example, Figure 5As shown, the plate limiting mechanism 9 includes a spacing adjustment module 901; two groups of fifth electric push rods 902 are symmetrically connected to the output end of the spacing adjustment module 901; two groups of clamping modules 903 are symmetrically connected to the output end of the two groups of fifth electric push rods 902; two groups of clamping plates 904 are connected to the output end of each group of clamping modules 903; a number of pressure rollers 905 are symmetrically and evenly spaced 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 group of clamping plates 904, and is connected to a group of brake pads 907.

[0029] When fixing the metal sheet, firstly, according to the size of the metal sheet, two groups of spacing adjustment modules 901 are controlled to drive four groups of fifth electric push rods 902 to adjust the spacing, and then the four groups of fifth electric push rods 902 are controlled to drive four groups of clamping modules 903 to move toward the edge of the sheet, and then the four groups of clamping modules 903 are controlled to drive four groups of clamping plates 904 to clamp the edges on both sides of the metal sheet, so that several groups of pressure rollers 905 are in contact with the top and bottom of the metal sheet, and then the eight groups of sixth electric push rods 906 are controlled to drive eight groups of brake pads 907 to contact with 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 detach from the metal sheet while several groups of pressure rollers 905 continue to support the metal sheet, and then the two groups of clamping modules 903 are controlled to move horizontally to expose the cutting part, which can not only fix metal sheets of any size, but also improve the working compatibility of the laser cutting device, but also avoid the occurrence of cutting blind areas and the need to adjust the position of the metal sheet, thereby improving the working efficiency of the laser cutting device.

[0030] For example, Figure 6 and Figure 7 As shown, the plate support mechanism 11 includes a support block 1101; a plurality of groups of support frame plates 1102 are sequentially sleeved on the outer wall of the support block 1101; a plurality of groups of first connecting holes 1103 are evenly distributed on the outer wall of each group of the support frame plates 1102; a second dust suction chamber 1106 is provided in each group of the support frame plates 1102; each group of the second dust suction chamber 1106 is connected with the corresponding plurality of groups of first connecting holes 1103; each group of the second dust suction chamber 1106 is connected with the telescopic slot 12; a first dust suction chamber 1105 is provided in the support block 1101; the first dust suction chamber 1105 is connected with the telescopic slot 12; a plurality of groups of second connecting holes 1104 are evenly distributed on the inner walls on the four sides of the first dust suction chamber 1105.

[0031] When performing laser cutting of technical plates, the corresponding groups of support frame plates 1102 can be controlled to shrink into the telescopic groove 12 according to the size of the metal plate, so that the edge of the metal plate is suspended in the air, which is convenient for laser cutting. At the same time, no matter how large the plate support mechanism 11 is adjusted to, the outermost side always has corresponding groups of first connecting holes 1103 exposed, so that when the slag generated by laser cutting of the metal plate falls, the second dust suction chamber 1106 dust suction pump will suck the slag into the telescopic groove 12 through the corresponding second dust suction chamber 1106 and the groups of first connecting holes 1103 for collection and storage. This not only can support the metal plate to achieve suspended cutting and avoid damage to the supporting part by the laser, but also can timely absorb and collect the slag, thereby improving the use effect of the laser cutting device.

[0032] By controlling the four groups of magnetic limit plates 705 to move toward the groove of the laser generator 8, when approaching the groove, the four groups of magnetic limit plates 705 will rotate toward the groove under the action of magnetism, and the laser generator 8 will be fixed after the four groups of magnetic limit plates 705 enter the groove. Not only can the laser generator 8 be quickly disassembled when it fails and needs maintenance, but also several groups of fourth electric push rods 703 can be controlled separately to adjust the angle of the laser generator 8, so that the edge of the cut metal sheet 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.

[0033] By controlling the corresponding groups of support frame plates 1102 to shrink into the telescopic groove 12, the edge of the metal plate is suspended in the air. No matter how large the plate support mechanism 11 is adjusted to, the corresponding groups of first connecting holes 1103 are always exposed on the outermost side. When the slag generated by laser cutting of the metal plate falls, the second dust suction chamber 1106 dust suction pump will suck the slag into the telescopic groove 12 for collection and storage through the corresponding second dust suction chamber 1106 and the groups of first connecting holes 1103. This not only can support the metal plate to achieve suspended cutting and avoid damage to the supporting part by the laser, but also can timely absorb and collect the slag, thereby improving the use effect of the laser cutting device.

[0034] By controlling several groups of pressure rollers 905 to press against the top and bottom of the metal sheet, and then controlling eight groups of brake pads 907 to press against 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 detach from the metal sheet while several groups of pressure rollers 905 continue to support the metal sheet, and then controlling the two groups of clamping modules 903 to move horizontally to expose the cutting part, it can not only fix metal sheets of any size, improving the working compatibility of the laser cutting device, but also avoid the occurrence of cutting blind spots and the need to adjust the position of the metal sheet, thereby improving the working efficiency of the laser cutting device.

[0035] By controlling the third electric push rod 18 to drive the support plate 16 to descend, several groups of universal wheels 17 are made to contact 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 re-stored into the storage groove 15, so that the processing platform 1 is re-contacted on the ground, so that the laser cutting device can remain stable when processing metal plates, thereby improving the convenience of using the laser cutting device.
