Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a laser cutting device for automotive door inner and outer panels. Background Technology

[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf (e.g., about 0.1 mm), thus completing the cutting of the material. Laser cutting is widely used in the processing of automotive parts.

[0003] In the prior art, such as Chinese patent CN211915854U, a laser cutting device for processing automobile mudguards is disclosed, including a cutting frame, a worktable, a baffle, a protective door, a laser cutting head, a pressure plate, and a cutting table. One end of the cutting frame is bolted to a processing table, and the upper part of the processing table is bolted to a cutting table. A mounting plate is bolted to the cutting frame, and an electric push cylinder is provided on the mounting plate. The bottom of the electric push cylinder is connected to a pressure plate. A stepper motor is also provided on the cutting frame, and a nut pair is provided on the outside of the ball screw. A support plate is welded to the side wall of the nut pair, and a laser controller is installed on the side wall of the support plate. The bottom side of the laser controller is connected to the laser cutting head.

[0004] Although the aforementioned patent solves the problem of high labor intensity in traditional manual cutting by using a laser cutting head, the laser beam generates high temperature and high energy density on the workpiece surface during the laser cutting process. The high energy density causes the workpiece surface to melt due to heat, and the temperature of the workpiece surface is too high after cutting, posing a risk of burns to people who directly contact the workpiece. Utility Model Content

[0005] The purpose of this invention is to solve the problem of excessively high surface temperature of workpieces after cutting, which poses a risk of burns to people who directly contact the workpieces, and to propose a laser cutting device for the inner and outer panels of automobile doors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laser cutting device for the inner and outer panels of an automobile door, comprising a cutting table, a support frame slidably connected to the top of the cutting table, a laser cutting assembly mounted on one side of the support frame, an auxiliary mechanism provided at the bottom of the laser cutting assembly, the auxiliary mechanism including a chip removal plate, a cooling plate, and a filter screen, a connecting plate fixedly connected to one side of the chip removal plate, a hydraulic cylinder fixedly connected to the top of the connecting plate, the hydraulic cylinder slidably connected to the support frame, a connecting pipe fixedly connected to the top of the chip removal plate, a dust collection box fixedly connected to one end of the connecting pipe, a filter screen fixedly connected to the inner wall of the dust collection box, and a slidably connected dust collection box to the support frame, a cooling fan fixedly connected to one side of the cooling plate, the bottom of the cooling fan fixedly connected to the cutting table, and a cooling plate fixedly connected to the top of the cutting table.

[0007] Preferably, a cooling pipe is embedded inside the cooling plate, one end of the cooling pipe is fixedly connected to a water pump, and one side of the water pump is fixedly connected to the cutting table.

[0008] Preferably, a reinforcing plate is fixedly connected to the top of the dust collection box, and one side of the reinforcing plate is fixedly connected to the dust collection box.

[0009] Preferably, an exhaust fan is installed inside the dust collection box, and a cutting head is provided on one side of the exhaust fan. The top of the cutting head is fixedly connected to the laser cutting assembly.

[0010] Preferably, an electric push rod is fixedly connected to the top of the cutting table, a positioning plate is fixedly connected to one side of the electric push rod, and the bottom of the positioning plate is slidably connected to the cutting table.

[0011] Preferably, the bottom of the cooling plate is engaged with a limiting plate, and the bottom of the limiting plate is slidably connected to the cutting table.

[0012] Preferably, a guide plate is fixedly connected to the top of the cutting table, one side of the guide plate is slidably connected to a limiting plate, and the limiting plate is connected to a lead screw by a thread, one end of the lead screw is fixedly connected to the output shaft of a motor, and one side of the motor is fixedly connected to the guide plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the water pump is connected to the cooling pipe. The water pump can accelerate the flow of coolant inside the cooling pipe, thereby ensuring the low temperature of the cooling plate surface. The top of the cooling plate contacts the plate for heat conduction. The cooling plate accelerates the air flow around the plate, thereby achieving rapid cooling of the plate and avoiding high temperature burns when the plate is moved. The chip removal plate can quickly absorb chips when the plate is cut, reducing the residue of chips or debris on the plate.

[0015] 2. In this utility model, an electric push rod is used to drive the positioning plate to move, and the plate slides on the top of the cutting table to move the plate to a designated area to achieve the position calibration of the plate. The motor drives the lead screw to rotate, and the lead screw drives the limiting plate to move on the top of the cutting table, thereby adjusting the distance between the two limiting plates, thereby achieving clamping and limiting of both sides of the plate, reducing the displacement of the plate during the cutting process, and thus improving the stability of the plate during cutting.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Reference Figure 1-4As shown: A laser cutting device for the inner and outer panels of an automobile door includes a cutting table 4, a support frame 1 slidably connected to the top of the cutting table 4, a laser cutting assembly 3 mounted on one side of the support frame 1, and an auxiliary mechanism at the bottom of the laser cutting assembly 3. The auxiliary mechanism includes a chip removal plate 6, a cooling plate 12, and a filter screen 20. A connecting plate 17 is fixedly connected to one side of the chip removal plate 6, and a hydraulic cylinder 16 is fixedly connected to the top of the connecting plate 17. The hydraulic cylinder 16 is slidably connected to the support frame 1. A connecting pipe 18 is fixedly connected to the top of the chip removal plate 6, and a dust collection box 2 is fixedly connected to one end of the connecting pipe 18. The inner wall of the dust collection box 2 is fixedly connected to the filter screen 20. The dust collection box 2 is slidably connected to the support frame 1. A cooling fan 10 is fixedly connected to one side of the cooling plate 12. The bottom of the cooling fan 10 is fixedly connected to the cutting table 4. A cooling plate 8 is fixedly connected to the top of the cutting table 4. A cooling pipe 13 is embedded inside the cooling plate 8. A water pump 14 is fixedly connected to one end of the cooling pipe 13. One side of the water pump 14 is fixedly connected to the cutting table 4. A reinforcing plate 15 is fixedly connected to the top of the dust collection box 2. One side of the reinforcing plate 15 is fixedly connected to the dust collection box 2. An exhaust fan is installed inside the dust collection box 2. A cutting head 19 is set on one side of the exhaust fan. The top of the cutting head 19 is fixedly connected to the laser cutting assembly 3.

[0025] By utilizing the sliding connection between the support frame 1 and the cutting table 4, the laser cutting assembly 3 can move on top of the cutting table 4. The chip removal plate 6 is connected to the dust collection box 2 via the connecting pipe 18. When the exhaust fan inside the dust collection box 2 is working, a negative pressure is generated inside the connecting pipe 18 and the chip removal plate 6, sucking the debris from the top of the sheet metal into the chip removal plate 6, and then into the dust collection box 2 through the connecting pipe 18. Since the dust collection box 2 is equipped with a filter screen 20, it can filter the debris in the air, thus keeping the debris in the dust collection box 2. The air is collected and discharged from the through hole on one side of the dust collection box 2 to remove dander. The air discharged by the cooling fan 10 can be sent into the cooling plate 12. The cooling plate 12 has a through hole on the side near the plate. The cooling plate 12 can be used to assist in the heat dissipation of the top of the plate. The cooling plate 8 is made of metal and can quickly conduct heat. The cooling pipe 13 is installed inside the cooling plate 8. The coolant inside the cooling pipe 13 can quickly remove the heat from the surface of the cooling plate 8, thereby ensuring the cooling effect of the cooling plate 8 on the plate.

[0026] Example 2

[0027] like Figures 1-3 As shown, an electric push rod 5 is fixedly connected to the top of the cutting table 4, and a positioning plate 9 is fixedly connected to one side of the electric push rod 5. The bottom of the positioning plate 9 is slidably connected to the cutting table 4. The bottom of the cooling plate 12 is engaged with a limiting plate 7. The bottom of the limiting plate 7 is slidably connected to the cutting table 4. A guide plate 11 is fixedly connected to the top of the cutting table 4. One side of the guide plate 11 is slidably connected to the limiting plate 7. The limiting plate 7 is connected to a lead screw by a thread. One end of the lead screw is fixedly connected to the output shaft of the motor 21. One side of the motor 21 is fixedly connected to the guide plate 11.

[0028] The position of the positioning plate 9 on the top of the cutting table 4 can be adjusted by the electric push rod 5, so that the plate moves synchronously when the positioning plate 9 moves, thereby realizing the position adjustment of the plate. The bottom of the cooling plate 12 is engaged with the limiting plate 7, and the limiting plate 7 can provide stable support for the bottom of the cooling plate 12. The lead screw is installed in the guide plate 11 and rotates between the guide plate 11. There are two lead screws in total. When the motor 21 drives the lead screw to rotate, the lead screw can drive the limiting plate 7 to move along the guide plate 11, thereby changing the distance between the two limiting plates 7 and realizing the clamping and limiting of the side wall of the plate.

[0029] The usage and working principle of this device are as follows: First, place the inner and outer panels of the car door to be cut on the cutting table 4, between the two limiting plates 7. Use the electric push rod 5 to drive the positioning plate 9 to move until one side of the panel overlaps with the guide plate 11. Then, use the motor 21 to drive the lead screw to rotate. The lead screw drives the limiting plate 7 to move closer to the panel, thus limiting the panel. Use the drive structure on the cutting table 4 to drive the support frame 1 and the laser cutting assembly 3 to move synchronously. Use the cutting head 19 to cut the panel. During cutting, the exhaust fan inside the filter screen 20 works. The exhaust fan is located at the top of the inner cavity of the dust collection box 2. It draws the debris into the dust collection box 2 through the chip removal plate 6 and filters it through the filter screen 20 to remove the debris. During the chip removal process, the cooling pipe 13 is filled with coolant. The cooling plate 8 is made of metal, which can quickly cool the bottom of the panel. After cutting, use the cooling fan 10 to blow air. The air is discharged from the ventilation hole on one side of the cooling plate 12 to cool and protect the top of the panel.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
