Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a laser cutting device for thin metal sheets. Background Technology

[0002] Laser cutting uses a high-power-density laser beam to irradiate the material being cut, quickly heating the material to its vaporization temperature and causing it to evaporate and form holes. As the beam moves across the material, the holes continuously form a very narrow kerf, completing the cutting of the material.

[0003] The present publication number CN219787016U discloses a laser cutting device for metal sheets, comprising: an operating table, a laser cutting head disposed above the operating table, a through hole disposed at the top of the operating table, and a movable moving plate disposed therein; a positioning mechanism disposed at the top of the moving plate for positioning the metal sheet; the positioning mechanism includes a U-shaped block, the bottom end of which is fixedly connected to the top of the moving plate.

[0004] While the above solution offers many advantages, it also has the following drawbacks: when fixing metal plates, the device requires rotating multiple bolts to secure the position of the metal plates, which is cumbersome to operate. Furthermore, the lack of protection during laser cutting makes it easy for waste slag to splatter everywhere, resulting in poor overall performance. Utility Model Content

[0005] The purpose of this invention is to provide a laser cutting device for thin metal sheets, which solves the problems in the prior art where multiple bolts need to be rotated to fix the position of the metal sheet, making the operation cumbersome. Furthermore, the lack of protection during laser cutting causes waste to splatter everywhere, resulting in poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting device for thin metal sheets, including a worktable, a movable laser cutting component fixedly installed on the top of the worktable, a collection frame slidably installed on the inner side of the worktable, two support plates slidably installed on the inner top of the worktable, a limit component fixedly installed between the two support plates and the worktable, a fixed protective structure provided on the top of the two support plates, the fixed protective structure including four first screws, the four first screws being rotatably installed on the top of the two support plates respectively, a fixing rod threadedly connected to the outer side of each of the four first screws, two limiting vertical plates fixedly installed on the top of each of the two support plates, the four limiting vertical plates passing through the four fixing rods and slidingly contacting the four fixing rods respectively, the vertical plates can effectively limit the fixing rods and prevent the fixing rods from rotating when the first screws rotate.

[0007] Preferably, a first gear is fixedly installed on the top of each of the four first screws, and the four first gears are in pairs. A rack is meshed with the outer side of each pair of first gears. A limit seat is fixedly installed on the top of each of the two support plates. The two racks pass through the two limit seats respectively and slide in contact with the two limit seats respectively. The limit seats can support and limit the racks to prevent the racks from disengaging from the first gears.

[0008] Preferably, a first fixed seat is fixedly installed on the top of the workbench, and a second screw is rotatably installed on one side of the first fixed seat. A movable frame is threadedly connected to the outer side of the second screw. Two limiting posts are fixedly installed on one side of the first fixed seat. Both limiting posts penetrate the movable frame and slide in contact with the movable frame. The limiting posts can effectively limit the movable frame and prevent the movable frame from rotating with the second screw.

[0009] Preferably, an I-shaped block is fixedly installed on one side of each of the two racks, and the movable frame has two square sliding grooves. The two I-shaped blocks are respectively disposed inside the two square sliding grooves and slide in contact with the movable frame. Through the cooperation of the I-shaped blocks and the square sliding grooves, the I-shaped blocks can be driven to move along with the movable frame when it moves back and forth, and the position of the movable frame will not be affected when the I-shaped blocks move left and right.

[0010] Preferably, one end of the second screw passes through the first fixed seat and is fixedly installed with a first bevel gear. Two second fixed seats are fixedly installed on one side of the first fixed seat. A second bevel gear is rotatably installed on one side of each of the two second fixed seats. Both second bevel gears are meshed with the first bevel gear. A third screw is rotatably installed on the other side of each of the two second fixed seats. One end of each third screw passes through the two second fixed seats and is fixedly connected to the two second bevel gears. A movable plate is threaded to the outer side of each of the two third screws. A protective cover is fixedly installed on one side of each of the two movable plates.

[0011] Preferably, two T-shaped plates are fixedly installed at the bottom of each of the two protective covers, and two T-shaped grooves are opened at the top of the workbench. The four T-shaped plates are respectively set inside the two T-shaped grooves and slide in contact with the workbench. The T-shaped grooves and T-shaped plates can effectively limit the movement of the protective covers and ensure that the movement position of the protective covers will not deviate.

[0012] Preferably, an L-shaped plate is fixedly installed on one side of the first fixing seat, and a motor is fixedly installed on one side of the L-shaped plate. The output end of the motor passes through the L-shaped plate and is fixedly connected to the first bevel gear.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This application uses a motor to drive the first bevel gear to rotate, which in turn drives the second screw to rotate, thereby moving the movable frame. The movable frame drives two racks to move through two I-shaped blocks, which in turn drives two sets of first gears to mesh and rotate, thereby driving the four first screws to rotate, which in turn moves the four fixed rods downward to fix the placed metal plate. This eliminates the need for workers to rotate the bolts one by one to fix the plate, reducing the time required for fixing and making the device more convenient to use.

[0015] 2. This application uses a first bevel gear to drive two second bevel gears to mesh and rotate, which in turn drives two third screws to rotate. This causes two moving plates and their protective covers to move in opposite directions to shield the top of the worktable. Then, the metal sheet is laser-cut using a moving laser cutting assembly. This effectively prevents waste from flying everywhere during laser cutting and improves the efficiency of the device. Attached Figure Description

[0024] The structural technology of the movable laser cutting component 2 and the limiting component 5 adopts the specific structure of a metal sheet laser cutting device disclosed in CN219787016U.

[0025] The top of each of the four first screws 6 is fixedly mounted with a first gear 9. The four first gears 9 are in pairs. The outer sides of the two pairs of first gears 9 are meshed with racks 10. The top of each of the two support plates 4 is fixedly mounted with a limiting seat 11. The two racks 10 pass through the two limiting seats 11 respectively and slide in contact with the two limiting seats 11 respectively.

[0026] A first fixed seat 13 is fixedly installed on the top of the workbench 1. A second screw 14 is rotatably installed on one side of the first fixed seat 13. A movable frame 15 is threadedly connected to the outer side of the second screw 14. Two limiting posts 16 are fixedly installed on one side of the first fixed seat 13. Both limiting posts 16 penetrate the movable frame 15 and slide in contact with the movable frame 15.

[0027] Two I-shaped blocks 12 are fixedly installed on one side of each of the two racks 10. The movable frame 15 has two square sliding grooves. The two I-shaped blocks 12 are respectively set inside the two square sliding grooves and slide in contact with the movable frame 15.

[0028] One end of the second screw 14 passes through the first fixing seat 13 and is fixedly installed with the first bevel gear 17. Two second fixing seats 18 are fixedly installed on one side of the first fixing seat 13. Two second bevel gears 19 are rotatably installed on one side of each of the two second fixing seats 18. Both second bevel gears 19 are meshed with the first bevel gear 17. A third screw 20 is rotatably installed on the other side of each of the two second fixing seats 18. One end of each third screw 20 passes through the two second fixing seats 18 and is fixedly connected to the two second bevel gears 19. A movable plate 21 is threaded to the outer side of each of the two third screws 20. A protective cover 22 is fixedly installed on one side of each of the two movable plates 21.

[0029] Two T-shaped plates 23 are fixedly installed at the bottom of each of the two protective covers 22. Two T-shaped slides are opened at the top of the worktable 1. The four T-shaped plates 23 are respectively set inside the two T-shaped slides and slide in contact with the worktable 1.

[0030] An L-shaped plate 24 is fixedly installed on one side of the first fixed base 13, and a motor 25 is fixedly installed on one side of the L-shaped plate 24. The output end of the motor 25 passes through the L-shaped plate 24 and is fixedly connected to the first bevel gear 17.

[0031] It should be noted that this utility model is a laser cutting device for thin metal sheets.

The motor 25 will drive the first bevel gear 17 to rotate, thereby driving the second screw 14 to rotate, which in turn drives the moving frame 15 to move. The moving frame 15 will drive the two racks 10 to move through the two I-shaped blocks 12, thereby driving the two sets of first gears 9 to mesh and rotate, which in turn drives the four first screws 6 to rotate, thereby driving the four fixing rods 7 to move downward to fix the placed metal sheet. There is no need for the operator to rotate the bolts one by one to fix them, which reduces the fixation time and makes the device more convenient to use.

[0032] During the process of fixing the metal sheet, the first bevel gear 17 drives the two second bevel gears 19 to mesh and rotate, thereby driving the two third screws 20 to rotate as well. This causes the two moving plates 21 and the protective cover 22 on one side to move in opposite directions to shield the top of the worktable 1. Then, the metal sheet is laser-cut by the moving laser cutting assembly 2, which effectively prevents the waste generated during laser cutting from splashing everywhere and improves the efficiency of the device.
