[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a CNC lathe with a protective structure, including a CNC machine body 1, a data display screen 2 mounted on the surface of the CNC machine body 1, a sensor 3 mounted on the surface of the CNC machine body 1, and a protective device 4 on the surface of the CNC machine body 1, which achieves the effect of protecting the data display screen 2, avoiding the situation where the data display screen 2 is corroded by liquids such as coolant and oil, resulting in short circuits and making it difficult to continue viewing the data, thus improving the practicality of the device. The surface of the CNC machine body 1 is provided with a disassembly device 5, which achieves the effect of disassembling and replacing the sensor 3, avoiding the situation where the CNC machine body 1 cannot identify the operator when it is unable to complete the machining due to the sensor 3 being damaged and difficult to disassemble, thus preventing the operator from being injured. This further improves the practicality of the device.

[0029] The specific design and function of its protective device 4 and disassembly device 5 will be explained below.

[0030] Reference Figure 2 , Figure 3 as well as Figure 4As shown, in this embodiment: the protective device 4 includes a connecting block 401, which is fixedly connected to the surface of the CNC machine body 1. Connecting rods 402 are fixedly connected to both ends of the connecting block 401. Support plates 403 are fixedly connected to the ends of the two connecting rods 402 that are far apart from each other. Rotating rods 404 are fixedly connected to the sides of the two support plates 403 that are close to each other. A protective cover 406 is rotatably connected to the arc surface of the rotating rod 404. A fixing block 411 is fixedly connected to the surface of the protective cover 406. A fixing hole is provided on the arc surface of the fixing block 411. A support block 407 is fixedly connected to the surface of the data display screen 2. A screw rod 408 is fixedly connected to one side of the 7. A strip plate 409 is rotatably connected to the arc surface of the screw rod 408. A fixing rod 410 is slidably inserted into the strip plate 409. A positioning plate 412 is fixedly connected to the surface of the fixing block 411. The size of the fixing rod 410 matches the size of the fixing hole on the surface of the fixing block 411. By pushing the protective cover 406 to rotate on the arc surface of the rotating rod 404, the protective cover 406 drives the fixing block 411, and the fixing block 411 drives the positioning plate 412 until the protective cover 406 is in contact with the surface of the data display screen 2. Then, the strip plate 409 is rotated and pushed to rotate on the arc surface of the screw rod 408. 409 drives the fixing rod 410 until it touches the positioning plate 412, achieving a quick positioning effect for the fixing rod 410. This allows staff to quickly protect the data display screen 2, reducing the probability of liquid splashing onto it. A baffle 413 is fixedly connected to the arc surface of the fixing rod 410. The size of the baffle 413 matches the strip plate 409. By pulling the fixing rod 410, it slides within the strip plate 409, causing the baffle 413 to touch the strip plate 409, thus blocking the fixing rod 410 and preventing shaking caused by external factors. This causes the fixing rod 410 to slip off from the strip plate 409, resulting in damage to the fixing rod 410 and making it unusable. The arc surface of the rotating rod 404 is fitted with two torsion springs 405. The two ends of the torsion springs 405 are fixedly connected to the support plate 403 and the protective cover 406, respectively. When the fixing of the protective cover 406 is released, the torque of the torsion springs 405 drives the protective cover 406 to rotate on the arc surface of the rotating rod 404 until the protective cover 406 is fully opened, achieving the effect of automatically opening the protective cover 406. This reduces the number of operation steps for the staff, increases the work efficiency of the staff, and improves the convenience of the device.

[0031] Reference Figure 5As shown, specifically, the disassembly device 5 includes two short rods 51, which are fixedly connected to the surface of the CNC machine body 1. An elliptical plate 54 is fixedly connected to one end of each short rod 51. A push plate 52 is slidably connected to the arc surface of each short rod 51. A limiting rod 55 is slidably inserted into the push plate 52. A circular plate 57 is fixedly connected to one end of the limiting rod 55. Two limiting grooves 58 are formed on the surface of the sensor 3. A spring 56 is fitted onto the arc surface of the limiting rod 55. The two ends of the spring 56 are fixedly connected to the circular plate 57 and the push plate 52, respectively. When the circular plate 57 is released, the rebound force of the spring 56 drives the circular plate 57, which in turn drives the limiting rod 55 to slide within the push plate 52 until the limiting rod 55 inserts into the limiting groove 58. This achieves a stable connection of the limiting rod 55, preventing the limiting rod 55 from disengaging from the sensor 3 due to shaking during processing. In this case, a rotating ring 53 is rotatably connected to the arc surface of the push plate 52. The surface of the rotating ring 53 is fixedly connected to the push plate 52. A recycling groove is opened on the surface of the CNC machine body 1. The limit rod 55 is pulled out from the limit groove 58, and then the rotating ring 53 is rotated. The rotating ring 53 drives the push plate 52 to rotate on the arc surface of the short rod 51. The push plate 52 drives the limit rod 55, and the limit rod 55 drives the circular plate 57 until the limit rod 55 is perpendicular to the recycling groove on the surface of the CNC machine body 1. Then the circular plate 57 is pushed, and the circular plate 57 drives the limit rod 55 to slide in the push plate 52 until the limit rod 55 is inserted into the recycling groove on the surface of the CNC machine body 1. This achieves the effect of rotating and recycling the limit rod 55, avoiding the shaking caused by external factors, which would cause the limit rod 55 to slide back and forth in the push plate 52, thus requiring the operator to keep pulling the limit rod 55.

[0032] Working principle: When protection is required, the protective cover 406 is pushed to rotate on the arc surface of the rotating rod 404. The protective cover 406 drives the fixing block 411, which in turn drives the positioning plate 412 until the protective cover 406 is in contact with the surface of the data display screen 2. Then, the strip plate 409 is rotated on the arc surface of the screw rod 408, which drives the fixing rod 410 until it touches the positioning plate 412. The fixing rod 410 is then pushed to slide within the strip plate 409 until it inserts into the fixing hole on the surface of the fixing block 411. When it is necessary to release the protection, the protective cover 406 is rotated to rotate on the arc surface of the rotating rod 404. The protective cover 406 drives the fixing block 410 until it touches the positioning plate 412. The fixing rod 410 is then pushed to slide within the strip plate 409 until it inserts into the fixing hole on the surface of the fixing block 411. When protecting the data display screen 2, the fixed rod 410 is pulled and slids within the strip plate 409. The fixed rod 410 drives the baffle 413 until the baffle 413 touches the strip plate 409. The torque of the torsion spring 405 drives the protective cover 406 to rotate on the arc surface of the rotating rod 404 until the protective cover 406 is fully opened. This achieves the effect of protecting the data display screen 2, preventing the data display screen 2 from being corroded by liquids such as coolant and oil and short-circuiting, which would cause the display screen to malfunction and make it difficult to continue viewing the data. This improves the practicality of the device.

[0033] When the damaged sensor 3 needs to be replaced, pull the limiting rod 55 out of the limiting groove 58, then rotate the rotating ring 53. The rotating ring 53 drives the push plate 52 to rotate on the arc surface of the short rod 51. The push plate 52 drives the limiting rod 55, and the limiting rod 55 drives the circular plate 57 until the limiting rod 55 is perpendicular to the recycling groove on the surface of the CNC machine body 1. Then push the circular plate 57, and the circular plate 57 drives the limiting rod 55 to slide within the push plate 52 until the limiting rod 55 is inserted into the recycling groove on the surface of the CNC machine body 1. After replacement, rotate the rotating ring 53 again, and the rotating ring 53 drives the push plate 52 on the arc surface of the short rod 51. The circular surface rotates, pushing plate 52 drives limit rod 55, limit rod 55 drives circular plate 57 until limit rod 55 is perpendicular to limit groove 58. Circular plate 57 is released, and the rebound force of spring 56 drives circular plate 57. Circular plate 57 drives limit rod 55 to slide within pushing plate 52 until limit rod 55 is inserted into limit groove 58. This achieves the effect of disassembling and replacing sensor 3, avoiding the situation where sensor 3 is damaged and difficult to disassemble, making it difficult for CNC machine body 1 to identify the operator during processing, thus potentially causing injury to the operator. This improves the practicality of the device.
