[0027] like Figures 1 to 6As shown, a specific embodiment of the utility model provides a closed protection mechanism for a moving column CNC grinder, including a CNC grinder body 1, a protection cover 2 arranged in the CNC grinder body 1, and a connection box 3 fixedly connected to the top of the protection cover 2, a magnet layer 4 is fixedly connected to the protection cover 2, and the magnet layer 4 is provided to facilitate the CNC grinder body 1 to produce metal debris and metal dust that can be adsorbed on the magnet layer 4 when the CNC grinder body 1 is processing, and a recovery component for collecting metal dust is provided in the protection cover 2, and the recovery component is provided to facilitate the collection of metal debris and metal dust adsorbed on the magnet layer 4, so as to avoid the need to recycle the metal debris and metal on the inner wall of the protection cover 2 after the processing is completed, and the recovery component includes The protective cover 2 includes a push plate 5, a round rod 6, a round ring 7 is slidably connected to the round rod 6, a movable frame 8 is fixedly connected to the round ring 7, and a scraper 9 is provided on one side of the movable frame 8; it also includes a dust reduction component arranged in the protective cover 2 for processing internal metal dust. By setting the dust reduction component, the metal dust dispersed in the protective cover 2 can be subjected to dust reduction treatment to avoid visual blurring inside the protective cover 2 due to excessive metal dust, which affects the judgment of external staff on the internal processing conditions. The dust reduction component includes a nozzle 10 arranged in the protective cover 2, a water outlet pipe 11 is fixedly connected to the nozzle 10, a transfer pipe 12 is slidably connected to the water outlet pipe 11, and a water inlet pipe 13 is provided on the transfer pipe 12.

[0028] like Figures 1 to 5 As shown, specifically, a receiving groove 14 is provided in the CNC grinding machine body 1, and the protective cover 2 is slidably connected in the receiving groove 14, a sealing plate 15 is slidably connected in the receiving groove 14, and the sealing plate 15 is fixedly connected to the round rod 6. The provision of the receiving groove 14 allows the protective cover 2 and the structural components inside the protective cover 2 to move into it, which is convenient for the protective cover 2 to be opened or closed. The provision of the sealing plate 15 allows the sealing plate 15 to seal the receiving groove 14 after the protective cover 2 is moved out of the receiving groove 14, thereby preventing metal dust generated by the CNC grinding machine body 1 during processing from entering the receiving groove 14. When the CNC grinding machine body 1 is processed, the metal debris generated by the processing and The metal dust will splash to both sides and be adsorbed on the magnet layer 4. A motor 16 is fixedly installed on the connecting box 3. A threaded rod 17 is fixedly connected to the output shaft of the motor 16, and the threaded rod 17 is rotatably connected to the push plate 5. A limiting groove 18 is provided in the connecting box 3. A movable plate 19 is slidably connected in the limiting groove 18, and the movable plate 19 is threadedly connected to the threaded rod 17. A connecting rod is fixedly connected between the push plate 5 and the movable plate 19, and the water outlet pipe 11 is rotatably connected to the movable plate 19. The starting motor 16 drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the movable plate 19 to move upward along the limiting groove 18, so that the movable plate 19 drives the push plate 5 to move upward through the connecting rod.

[0029] like Figures 3 to 5As shown, specifically, a push rod 20 is rotatably connected between the push plate 5 and the circular ring 7, and a direct-acting electromagnet 21 is fixedly connected between the moving frame 8 and the scraper 9. The direct-acting electromagnet 21 is started to push the scraper 9 to close to the magnet layer 4, and the push plate 5 moves upward and the circular ring 7 slides toward the middle of the circular rod 6 under the cooperation of the push rod 20. The sliding of the circular ring 7 drives the moving frame 8 at the bottom to move. At this time, the moving frame 8 drives the direct-acting electromagnet 21 and the scraper 9 to move, so that the scraper 9 pushes and cleans the metal debris and metal dust adsorbed on the magnet layer 4 when moving. A retaining groove plate 22 extending to the bottom of the CNC grinder body 1 is fixedly connected to the protective cover 2, and the long grooves between the two sides of the retaining groove plate 22 and the protective cover 2 are adapted to the scraper 9 until the ring 7 moves to When the round rod 6 is in the middle, the scraper 9 pushes the metal debris and metal dust to move to the baffle plate 22. At this time, the scraper 9 moves into the long slots between the two sides of the baffle plate 22 and the protective cover 2, and the pushed metal debris and metal dust fall out through the baffle plate 22. At this time, the external staff can place a recovery bucket or other device at the bottom of the baffle plate 22 to hold the metal debris and metal dust, and then reversely drive the motor 16 to reverse the threaded rod 17 to drive the moving plate 19 to move downward. At this time, the reverse driving direct-acting electromagnet 21 drives the scraper 9 away from the magnet layer 4, so that the scraper 9 will not push the metal debris and metal dust on the magnet layer 4 to both sides during the resetting process, until the moving frame 8 is reset to the initial state under the action of the ring 7 and the push rod 20.

[0030] like Figure 3 , Figure 5 and Figure 6As shown, specifically, a spring 23 is fixedly connected between the water outlet pipe 11 and the transfer pipe 12, a through hole 24 is opened in the transfer pipe 12, an isolation groove 25 is opened in the water inlet pipe 13, and the through hole 24 is located in the isolation groove 25, a limit block 26 is fixedly installed in the water inlet pipe 13, the water inlet pipe 13 is fixedly installed on the connection box 3, the water outlet pipe 11 is fixedly connected to the push plate 5, the water inlet pipe 13 should be connected to the external water pipe, at the same time, the movable plate 19 drives the push plate 5 to move upward, and the push plate 5 drives the water outlet pipe 11 to move upward, so that the water outlet pipe 11 pushes the top transfer pipe 12 to move upward along the inside of the water inlet pipe 13, and the through hole 24 in the isolation groove 25 moves out of the isolation groove 25 during the movement, so that the water in the water inlet pipe 13 can flow into the transfer pipe 12 and the water outlet pipe 11 at the bottom through the through hole 24 until It is sprayed outward from the nozzle 10, and the discharged water can reduce the metal dust in the protective cover 2 until the transfer pipe 12 moves to the limit block 26. Under the blocking effect of the limit block 26, the transfer pipe 12 stops moving, and the water outlet pipe 11 continues to move upward under the action of the push plate 5, so that the spring 23 is forced to contract and produce a reaction force. When the moving plate 19 drives the push plate 5 and the water outlet pipe 11 to move downward, the reaction force of the spring 23 makes the transfer pipe 12 at the top still at the limit block 26. At this time, the water in the water inlet pipe 13 can continue to be sprayed into the protective cover 2 until the moving plate 19 moves downward to the initial position, and the spring 23 no longer produces a reaction force, so that the through hole 24 moves again into the isolation groove 25, and then the water in the water inlet pipe 13 is no longer sprayed into the protective cover 2.

[0031] like Figure 1 As shown, specifically, a viewing port 27 is provided on the protective cover 2 , and a transparent glass is provided in the viewing port 27 . The transparent glass makes it easy to observe the processing conditions in the protective cover 2 through the viewing port 27 .
