At the same time, the slider 204 is in sliding connection with the inner wall of the annular slide rail shell 206.

[0031] Embodiment one

[0032] Referring to Figures 1-6 In a medium-sized machining workshop, multiple CNC lathes are operating simultaneously. The safety protection device of the CNC lathe is installed on one of the CNC lathes. The working environment in the workshop is relatively complex, with a lot of personnel moving around and equipment running. During daily processing, the operator opens the sliding door 4 by the handle 6, enters the circular protective shell 1 through the entrance 3, and performs device debugging and workpiece clamping according to the normal process. During processing, the sliding door 4 is closed, and the circular protective shell 1 effectively blocks metal debris from splashing into the external area, ensuring the safety of other personnel and equipment in the workshop. When the processing is completed, the cleaning mechanism 2 is started, and the reduction motor 201 and the electric lifting rod 208 work cooperatively. The brush plate 209 sweeps the debris on the ground 10 and scrapes them into the collection trench 11 during the circular motion. The entire cleaning process is efficient and convenient, without the need for manual cleaning, greatly improving the cleanliness and work efficiency of the workshop.

[0033] Embodiment two

[0034] Referring to Figures 1-6 Figures 1-6 In a small precision parts processing enterprise, the precision and equipment life of the CNC lathe are required to be high. The protective device is installed on a high-precision CNC lathe. Since the precision of the processed parts is high, the debris produced is small but numerous. In actual operation, the fresh air mechanism 8 continuously provides fresh air to the inside, ensuring the cleanliness of the processing environment and avoiding the influence of small debris on the precision of the equipment. The cleaning mechanism 2 is started after each processing is completed, and the electric lifting rod 208 is controlled to accurately control the height of the brush plate 209, so that the brush plate 209 can accurately clean the small debris on the ground 10, and the scraper 212 can effectively scrape the debris into the collection trench 11. This automatic cleaning method not only reduces the labor intensity of workers, but also reduces the risk of damage to the equipment caused by manual cleaning, ensuring the high-precision processing performance and long service life of the CNC lathe.

[0035] Working principle: Before the CNC lathe starts operating, the operator can pull the sliding door 4 by the handle 6, enter the circular protective shell 1 through the entrance 3, and then perform device debugging, workpiece clamping, and other operations. At this time, the first window 5 and the second window 7 facilitate the operator to observe the internal situation of the equipment. The fresh air mechanism 8 starts to work, continuously providing fresh air to the inside of the circular protective shell 1, ensuring a good working environment.

[0036] Before the numerical control lathe processing, the sliding door 4 can be closed, and if cutting debris splashes during the numerical control lathe processing, the circular protective shell 1 can block the splashing of the debris to the external working area, prevent the injury to the operator, and avoid the scattering of the debris to affect the normal operation of the equipment and the subsequent processing quality.

[0037] After the processing is completed, the cleaning mechanism 2 is started. First, the brush plate 209 is moved out of the collection trench 11 by starting the electric lifting rod 208, and then the output end of the speed reducer motor 201 drives the rotating shaft 202 to rotate, and then drives the first plate 203 fixed at the bottom end of the rotating shaft 202 to move around the axis of the rotating shaft 202. During the movement of the first plate 203, the slider 204 on the upper surface thereof slides along the annular slide rod 205, and the annular slide rod 205 is fixed at both ends of the annular slide rail shell 206, and the annular slide rail shell 206 is fixedly connected with the inner top wall of the circular protective shell 1, which ensures the stability of the movement of the first plate 203.

[0038] When the first plate 203 moves, the second plate 207 fixedly connected to the bottom surface moves together. Then, the electric lifting rod 208 at the bottom surface of the second plate 207 is lowered according to actual needs, so that the brush plate 209 moves downward to the appropriate position, at which time the bristles 211 at the bottom surface of the brush plate 209 are in contact with the ground 10, and the scraper 212 is also in contact with the ground 10. Under the drive of the first plate 203, the brush plate 209 moves in a circular motion, the bristles 211 sweep the cutting debris on the ground 10, and the scraper 212 further sweeps the gathered debris, so that the debris can be gathered and scraped into the collection trench 11. The one end of the stabilizing rod 210 is fixedly connected with the upper surface of the brush plate 209, and the other end slides in the second plate 207 and extends to the outside, which plays a role in stabilizing the movement of the brush plate 209 and ensures the smooth operation of the sweeping and scraping actions.

[0039] With the continuous reciprocating movement of the brush plate 209, the swept and scraped cutting debris is gradually pushed into the collection trench 11, realizing the centralized collection of the cutting debris, which is convenient for subsequent unified cleaning. The whole process does not need frequent manual cleaning, greatly improves the cleaning efficiency, reduces the labor intensity and safety hazards of the cleaning workers, and also reduces the risk of secondary pollution or equipment damage caused by improper manual cleaning operation. The machine entity 14 is fixed on the mounting plate 13, and the mounting plate 13 is supported and fixed on the ground 10 by the circular shell rod 12, so that the bottom surface of the numerical control lathe can also be cleaned and collected.

[0040] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
