[0013] Furthermore, a monitoring method for a CNC machine tool machining status monitoring device includes the following steps: S1: When the industrial camera is placed inside the protective case, it will detect the processing status of the CNC machine tool. If any abnormality occurs, it will trigger an alarm. S2: Due to the squeezing force, the spring plate will drive the squeezing plate to push the rubber pads closer together, so as to fix the industrial camera. At the same time, when the squeezing plates are close together, they will squeeze the inclined plate through the thin rod, so as to move the pressure block downward and further fix the industrial camera. S3: When the bidirectional electric actuator is turned on, the output end will pull the long rod to move through the actuator, making them move closer or further apart. When the long rods move closer together, they will press the lifting plate through the hinge plate to move it downward. At the same time, the long rod will drive the cleaning brush to clean the impurities accumulated on the surface of the transparent plate. S4: The long rods move the soft brush on the surface of the protective box, cleaning the heat dissipation holes on the back to prevent them from becoming clogged and affecting the heat dissipation of the industrial camera. When the long rods get close to each other, they squeeze the long plate, which in turn moves the cleaning soft brush back and forth on the surface of the protective box.
[0014] The present invention has the following beneficial effects: When the industrial camera is placed inside the protective case, it monitors the processing status of the CNC machine tool. If any abnormality occurs, an alarm will sound, providing a rapid alert. Simultaneously, as the camera enters the case, the spring plate, due to its compressive force, pushes the rubber pads together, securing the camera. Furthermore, as the compressive plates approach each other, a thin rod presses the inclined plate, causing the pressure block to move downwards, further securing the camera and ensuring stable detection. During machine processing, vibrations occur. The limiting rod slides up and down within the limiting groove, causing the protective case to compress the shock-absorbing block within the support frame, reducing vibration and preventing inaccurate detection due to vibration.
[0015] When the bidirectional electric actuator is activated, the output end pulls the long rods to move closer or further apart. When the long rods move closer, they press the lifting plate downwards via the hinge plate. Simultaneously, the long rods drive the cleaning brush to clean impurities accumulated on the surface of the transparent plate. The cleaned impurities fall into the collection box for centralized collection, preventing impurity accumulation from affecting detection accuracy. Conversely, when the long rods move further apart, they drive the lifting plate upwards via the hinge plate. At this time, the lifting plate moves the transparent plate upwards inside the protective box via the elastic rod and the limiting slide bar, enabling quick disassembly, assembly, and replacement of the industrial camera. The side heat dissipation holes dissipate heat from the industrial camera, thereby improving its service life.
[0016] When the push rods of this invention approach each other, the long rods will drive the soft brush to move on the surface of the protective box, cleaning the heat dissipation holes on the back and preventing blockage of the heat dissipation holes from affecting the heat dissipation of industrial cameras. At the same time, when the long rods approach each other, they will squeeze the long plate, thereby driving the cleaning soft brush to move back and forth on the surface of the protective box, cleaning the heat dissipation holes on the side. The telescopic rod makes the position of the cleaning soft brush more stable when it moves.

The end of the long rod 50 is fixedly connected to the surface of the push rod 41. A long plate 51 is hinged to the top of the long rod 50.

[0030] Furthermore, a monitoring method for a CNC machine tool machining status monitoring device includes the following steps: S1: When the industrial camera 27 is placed inside the protective box 25, the industrial camera 27 will detect the processing status of the CNC machine tool body 1. When an abnormal problem occurs, it will trigger an alarm through the alarm device 2. S2: Due to the squeezing force, the spring plate 28 will drive the squeezing plate 29 to push the rubber pad 30 closer together, so as to fix the industrial camera 27. At the same time, when the squeezing plates 29 are close together, they will squeeze the inclined plate 33 through the thin rod 32, thereby causing the pressure block 34 to move downward, so as to further fix the industrial camera 27. S3: When the bidirectional electric actuator 40 is turned on, the output end will pull the long rod 42 to move through the push rod 41, making them move closer or further apart. When the long rods 42 move closer together, they will press the lifting plate 45 through the hinge plate 44 to move it downward. At the same time, the long rod 42 will drive the cleaning brush 47 to clean the impurities accumulated on the surface of the transparent plate 43. S4: The long rod 50 drives the soft brush 52 to move on the surface of the protective box 25, so as to clean the heat dissipation hole 53 on the back, and avoid the blockage of the heat dissipation hole 53 affecting the heat dissipation of the industrial camera 27.

[0031] When in use, the industrial camera 27 is placed inside the protective case 25. The industrial camera 27 monitors the machining status of the CNC machine tool body 1. If any abnormality occurs, the alarm device 2 will sound an alarm, providing a rapid alert. Simultaneously, when the industrial camera 27 enters the protective case 25, the spring plate 28, due to the squeezing force, will cause the squeezing plate 29 to push the rubber pads 30 closer together, thus securing the industrial camera 27. At the same time, when the squeezing plates 29 approach each other, the thin rod 32 will squeeze the inclined plate 33, causing the pressure block 34 to... The downward movement further secures the industrial camera 27, making its detection more stable. Simultaneously, during machine processing, vibrations occur. The limit rod 23 slides up and down within the limit groove 22, causing the protective box 25 to press against the shock-absorbing block 31 within the support frame 21, thus reducing vibration and preventing inaccurate detection due to vibration. When the bidirectional electric push rod 40 is activated, its output end pulls the long rod 42 via the push rod 41, moving them closer or further apart. When the long rods 42 approach each other, they press against the lifting plate 45 via the hinge plate 44. As it moves downwards, the long rod 42 drives the cleaning brush 47 to clean the impurities accumulated on the surface of the transparent plate 43. The cleaned impurities fall into the collection box 48 for centralized collection, preventing impurity accumulation from affecting the accuracy of detection. Conversely, when the long rods 42 move away from each other, they drive the lifting plate 45 upwards through the hinge plate 44. At this time, the lifting plate 45, through the elastic rod 46, causes the transparent plate 43 to move upwards inside the protective box 25 via the limiting slide rod 49, enabling quick disassembly, assembly, and replacement of the industrial camera 27. The side heat dissipation holes 26 provide ventilation for the industrial camera. The camera 27 performs heat dissipation to improve its service life. When the push rods 41 approach each other, the long rod 50 drives the soft brush 52 to move on the surface of the protective box 25, cleaning the heat dissipation holes 53 on the back and preventing the heat dissipation holes 53 from being blocked and affecting the heat dissipation of the industrial camera 27. At the same time, when the long rods 50 approach each other, they squeeze the long plate 51, which drives the cleaning soft brush 54 to move back and forth on the surface of the protective box 25, cleaning the heat dissipation holes 26 on the side. Meanwhile, the telescopic rod 56 makes the position of the cleaning soft brush 54 more stable when it moves.

The CNC machine tool machining status monitoring device according to claim 7, characterized in that: The long plate (51) is located above the long rod (50), the surface of the soft brush (52) is adapted to the surface of the back heat dissipation hole (53), the surface of the cleaning soft brush (54) is adapted to the surface of the side heat dissipation hole (26), the surface of the fixing plate (55) is fixedly connected to the upper surface of the protective box (25), and the telescopic rod (56) is located at a position where the cleaning soft brush (54) and the fixing plate (55) are close to each other.
9. The monitoring method of the CNC machine tool machining status monitoring device according to claim 8, characterized in that, Includes the following steps: S1: When the industrial camera (27) is placed inside the protective box (25), the industrial camera (27) will monitor the processing status of the CNC machine tool body (1). When an abnormal problem occurs, it will alarm through the alarm device (2). S2: The spring plate (28) will cause the extrusion plate (29) to push the rubber pad (30) closer together due to the extrusion force, so that it can fix the industrial camera (27). At the same time, when the extrusion plates (29) are close to each other, they will press the inclined plate (33) through the thin rod (32), so that the pressure block (34) moves downward, so that it can further fix the industrial camera (27). S3: When the bidirectional electric actuator (40) is turned on, the output end will pull the long rod (42) to move through the push rod (41), so that they move closer or further apart. When the long rods (42) move closer together, they will press the lifting plate (45) through the hinge plate (44) to move it downward. At the same time, the long rod (42) will drive the cleaning brush (47) to clean the impurities accumulated on the surface of the transparent plate (43). S4: The long rod (50) drives the soft brush (52) to move on the surface of the protective box (25) to clean the heat dissipation hole (53) on the back, so as to avoid the blockage of the heat dissipation hole (53) on the back and affect the heat dissipation of the industrial camera (27). At the same time, when the long rods (50) approach each other, they will squeeze the long plate (51) to drive the cleaning soft brush (54) to move back and forth on the surface of the protective box (25).
