[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 This utility model provides a technical solution: a protective cover for a vertical CNC machine tool, including a fixed frame 1, wherein the fixed frame 1 is configured as two sets, and the tops of the two sets of fixed frames 1 on opposite sides are fixedly connected by a connecting frame 2. A fixed connecting seat 3 is fixedly connected to the side wall of the fixed frame 1. A protective mechanism 4 for machine tool protection is provided on one side of the fixed frame 1. A drive mechanism 5 for automatic and manual opening of the protective mechanism 4 is provided on the protective mechanism 4. A position locking mechanism 6 for positioning the protective mechanism 4 is provided between the connecting frame 2 and the protective mechanism 4.

[0016] The fixed connecting seat 3 can install the fixed frame 1 on the machine tool, and the protective mechanism 4 can protect the surface of the machine tool. The drive mechanism 5 can realize the automatic opening and closing of the protective mechanism 4. In case of damage to the drive mechanism 5 or power failure, the protective mechanism 4 can be switched to manual opening and closing to ensure that the protective mechanism 4 can be used normally. The position locking mechanism 6 can position the protective mechanism 4 when it is manually opened to prevent the protective mechanism 4 from falling suddenly and causing safety hazards.

[0017] Please see Figure 1 and Figure 2 The protective mechanism 4 includes a slide rail 7, a first slider 8, a protective cover body 9, and a handle 10. The slide rail 7 is fixedly installed on one side of the fixed frame 1. The first slider 8 is slidably connected to the slide rail 7. The protective cover body 9 is fixedly connected to one side of the first slider 8. The handle 10 is fixedly installed on the protective cover body 9.

[0018] The protective cover body 9 and the first slider 8 can move up and down along the slide rail 7, which makes it easy to move the protective cover body 9 up and down and use the protective cover body 9 to protect the machine tool.

[0019] Please see Figures 1-3 The driving mechanism 5 includes an extension plate 11, a drive motor 12, a gear rack 13, and a gear disk 16. Extension plates 11 are fixedly installed on both sides of the protective cover body 9. A drive motor 12 is fixedly installed on the extension plate 11. A gear rack 13 is fixedly installed on the side wall of the fixing frame 1. The output end of the drive motor 12 is connected to a gear disk 16 that meshes with the gear rack 13. The driving mechanism 5 also includes a fixing frame 14, a telescopic rod 15, threaded holes 17, and locking bolts 18. The output end of the drive motor 12 is fixedly connected to the fixing frame 14. A telescopic rod 15 with a rectangular cross-section is slidably connected inside the fixing frame 14. One end of the telescopic rod 15 is fixedly connected to the gear disk 16. Two sets of threaded holes 17 are provided on the telescopic rod 15. A locking bolt 18, threadedly connected to the threaded holes 17, is provided on the top of the fixing frame 14.

[0020] When the protective cover body 9 needs to move up and down, the drive motor 12 drives the fixed frame 14, the telescopic rod 15 and the gear disk 16 to rotate. This allows the gear disk 16 to move along the gear rack 13 it meshes with, thus realizing the up and down movement and opening and closing of the protective cover body 9. When the drive motor 12 is damaged and cannot be used normally, the locking bolt 18 is unscrewed, allowing the telescopic rod 15 to move along the inside of the fixed frame 14. This allows the gear disk 16 and the gear rack 13 to disengage, thus realizing the manual opening and closing of the protective cover body 9. Then, the locking bolt 18 is tightened again into another set of threaded holes 17 to prevent the gear disk 16 from moving back to the position of the gear rack 13.

[0021] Please see Figure 1 , Figure 2 and Figure 4 The position locking mechanism 6 includes a positioning piece 19, a placement groove 20, a locking groove 21, a sliding rod 23, a second slider 24, and a locking post 25. The positioning piece 19 is fixedly installed on the top of the protective cover body 9. The top of the positioning piece 19 has a placement groove 20. The positioning piece 19 has an "L"-shaped locking groove 21 that communicates with the placement groove 20. The connecting frame 2 has an operating groove 22. The sliding rod 23 is fixedly connected inside the operating groove 22. The second slider 24 is slidably connected outside the sliding rod 23. The locking post 25 is fixedly connected to one side of the second slider 24 and at the position corresponding to the placement groove 20. A spring 26 is fixedly connected between one side of the inner wall of the operating groove 22 and one side of the second slider 24 and outside the sliding rod 23.

[0022] The spring 26 can push the second slider 24 and the locking pin 25 to one end of the operating groove 22, so that the locking pin 25 corresponds to the placement groove 20. This prevents the locking pin 25 from colliding with the positioning piece 19 when the protective cover body 9 moves up and down automatically. When the protective cover body 9 is manually opened, the locking pin 25 is inserted into the placement groove 20. Then, the locking pin 25 and the second slider 24 are pulled to move along the slide bar 23, and the locking pin 25 is engaged with the "L"-shaped locking groove 21, thereby preventing the protective cover body 9 from falling suddenly.

[0023] Please see Figure 1 The protective cover body 9 is provided with an observation window 27 made of transparent acrylic material. The observation window 27 made of transparent acrylic material has a certain rigidity and can also observe the processing status of the machine tool in a timely manner.

[0024] In use, firstly, the fixed connecting seat 3 allows the fixed frame 1 to be installed on the machine tool. Then, the protective mechanism 4 protects the machine tool surface. The drive mechanism 5 enables the automatic opening and closing of the protective mechanism 4. In case of damage to the drive mechanism 5 or power failure, the protective mechanism 4 can be switched to manual opening and closing to ensure normal operation. The position locking mechanism 6 positions the protective mechanism 4 during manual opening to prevent it from suddenly falling and causing safety hazards. The protective cover body 9 and the first slider 8 can move up and down along the slide rail 7, facilitating the vertical movement of the protective cover body 9 and protecting the machine tool. When the protective cover body 9 needs to be moved up and down, the drive motor 12 rotates the fixed frame 14, the telescopic rod 15, and the gear disk 16, causing the gear disk 16 to move along the meshing gear rack 13, thus achieving the vertical opening and closing of the protective cover body 9. When the drive motor 12 is damaged and cannot be used normally, unscrew the locking bolt 18 to move the telescopic rod 15 along the inside of the fixed frame 14, thereby disengaging the gear disk 16 and the gear rack 13. This allows the protective cover body 9 to be opened and closed manually. Then, tighten the locking bolt 18 into the other set of threaded holes 17 to prevent the gear disk 16 from moving back to the position of the gear rack 13. The spring 26 can push the second slider 24 and the locking pin 25 to one end of the operating groove 22, so that the locking pin 25 corresponds to the placement groove 20. This prevents the locking pin 25 from colliding with the positioning piece 19 when the protective cover body 9 moves up and down automatically. When the protective cover body 9 is opened manually, the locking pin 25 is inserted into the placement groove 20. Then, pull the locking pin 25 and the second slider 24 along the slide rod 23 and make the locking pin 25 engage with the "L"-shaped locking groove 21, thereby preventing the protective cover body 9 from falling suddenly.
