Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a cutting device for CNC machine tool production. Background Technology

[0002] Laser cutting devices in CNC machine tools are devices that use a high-power laser beam as a "tool" and precisely control the optical path through a CNC system to perform non-contact thermal cutting of materials. The core principle is to focus the laser beam onto the workpiece surface, causing the material to melt, vaporize, or ablate instantly through the conversion of light energy into heat energy. Assisted gas is then used to remove molten slag, achieving high-precision cutting.

[0003] During the operation of laser cutting equipment, it is necessary to monitor the shape of cutting sparks and the state of molten slag splashing. Currently, this is mostly observed by the naked eye, which can easily damage eyesight. In addition, the naked eye does not have the function of recording, which is not convenient for subsequent optimization work. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a cutting device for CNC machine tool production, including a laser cutting device body 1, and further comprising:

[0025] Machine monitoring mechanism 2 is installed on the main body 1 of the laser cutting device. Machine monitoring mechanism 2 is used to capture and monitor the working end of the main body 1 of the laser cutting device.

[0026] Dustproof mechanism 3 is installed on the machine monitoring mechanism 2. Dustproof mechanism 3 is used to reduce the impact of dust on the shooting end.

[0027] The machine monitoring mechanism 2 includes a connector 27. A rotating inner seat 271 is rotatably connected to the inner cavity of the connector 27. A positioning bolt 272 is threadedly connected to the end of the rotating inner seat 271. The positioning bolt 272 movably abuts against the outer wall of the connector 27. A protective cylinder 273 is fixedly installed on the inner surface of the rotating inner seat 271. A transparent protective lens 274 is fixedly installed at the end of the protective cylinder 273. A camera 275 is fixedly installed in the inner cavity of the protective cylinder 273. During the operation of the laser cutting device body 1, the camera 275 is controlled to work, which can monitor the working end of the laser cutting device body 1. The camera captures footage and uploads it to a computer. Users can remotely monitor the cutting process on the computer screen, avoiding potential eye strain and the risk of flying debris. The computer can also store the video data for later optimization. During maintenance, users can adjust the elevation angle of the camera 275. To do this, loosen the second positioning bolt 272 to release it from its contact with the outer wall of the connector 27. Then, rotate the inner seat 271 as a whole and adjust it. Finally, tighten the second positioning bolt 272 to lock the elevation angle of the camera 275.

[0028] As one implementation method in this embodiment, such as Figure 1 As shown, the machine monitoring mechanism 2 also includes a support 21, which is fixedly installed on the top of the laser cutting device body 1. A stepper motor 22 is fixedly installed on the top of the support 21. A rotating shaft 23 is fixedly connected to the output shaft of the stepper motor 22. A rotating seat 24 is fixedly installed at the bottom of the rotating shaft 23. The rotating seat 24 is rotatably connected to the top of the laser cutting device body 1. A connecting arm 25 is fixedly installed on the outer wall of the rotating seat 24. By controlling the stepper motor 22 to work, the connecting arm 25 can be driven to rotate through the rotating shaft 23 and the rotating seat 24. This can drive the connecting piece 27 to rotate slowly around the working end of the laser cutting device body 1, thereby realizing the function of automatically adjusting the image capture position and facilitating the effective monitoring work.

[0029] As one implementation method in this embodiment, such as Figure 3 As shown, a sleeve 26 is fixedly installed at the bottom of the connecting arm 25. A positioning bolt 261 is threadedly connected to the outer wall of the sleeve 26. An extension rod 262 is slidably connected in the inner cavity of the sleeve 26. The threaded end of the positioning bolt 261 is in movable contact with the outer wall of the extension rod 262. The connecting piece 27 is fixedly installed at the bottom of the extension rod 262. During maintenance, the user can adjust the height of the camera 275. When adjusting, loosen the positioning bolt 261, then slide the extension rod 262 inside the sleeve 26 to adjust, and then tighten the positioning bolt 261.

[0030] As one implementation method in this embodiment, such as Figure 5 As shown, the dustproof mechanism 3 includes a sleeve 31, which is fixedly installed on the outer wall of the rotating inner seat 271. A duct fan 32 is fixedly installed on the inner wall of the sleeve 31. The duct fan 32 is controlled to work and can output a relatively slow airflow for dustproof work.

[0031] As one implementation method in this embodiment, such as Figure 5 As shown, the air inlet of the duct fan 32 is threadedly connected to an air filter 33, and the exhaust port of the duct fan 32 is fixedly connected to a conical shroud 34. A flexible hose 35 is fixedly connected to the end of the conical shroud 34. The air filter 33 is used to filter the air absorbed by the duct fan 32, thereby enabling the duct fan 32 to output slow and clean air.

[0032] As one implementation method in this embodiment, such as Figure 5As shown, an annular tube 36 is fixedly connected to the end of the flexible tube 35. The annular tube 36 is fixedly installed on the outside of the transparent protective lens 274. A through hole 37 is opened on the inner surface of the annular tube 36. A raised ring 38 is fixedly installed on the side of the annular tube 36. Slow and clean air will pass through the conical cover 34 and the flexible tube 35 and enter the interior of the annular tube 36. The air will then be output from the through hole 37, making the transparent protective lens 274 under positive pressure, reducing the dust coverage of the transparent protective lens 274, ensuring the image shooting effect, and reducing the frequency of cleaning the transparent protective lens 274 by the user.

[0033] It is worth noting that the stepper motor 22, camera 275, computer, and duct fan 32 in this solution are devices that can be purchased commercially by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate further on this aspect. Furthermore, this solution aims to protect the physical structure, but does not protect the circuitry and software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0034] Working Principle: During operation, the laser cutting device body 1 controls the camera 275 to capture images of the working end of the laser cutting device body 1, which are then uploaded to a computer. Users can remotely observe the cutting status through the computer screen, avoiding potential eye strain and the danger of flying debris. The computer can also store the video data for later optimization. The user can control the stepper motor 22 via the computer, which drives the connecting arm 25 to rotate via the rotating shaft 23 and rotating base 24. This drives the connecting piece 27 to rotate slowly around the working end of the laser cutting device body 1, thus automatically adjusting the image capture position for effective monitoring. The user can also control the duct fan 32 to output slow, clean air, which is then output from the through hole 37, creating a positive pressure at the transparent protective lens 274. This reduces the dust coverage at the transparent protective lens 274, ensuring the quality of the captured image.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
