[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] Embodiment 1:

[0020] like Figure 1-3As shown, a device for collecting machining debris of a numerically controlled machine tool comprises a machine tool 1, a scraper 2 for scraping off metal debris is slidably connected to the top of the machine tool 1, the scraper 2 is set to an L-shaped structure and baffles are installed on both sides, the baffles can intercept all the debris inside the scraper 2 when the scraper 2 removes the debris, and the debris will not be pushed off from both sides of the machine tool 1, a push block 3 for driving the scraper 2 to move is provided on one side of the scraper 2, a screw rod 4 for moving the push block 3 is provided on one side of the machine tool 1, a limit block 14 for making the push block 3 move only horizontally is horizontally slidably provided on one side of the machine tool 1, a motor 5 for driving the screw rod 4 to rotate is installed at one end of the screw rod 4, a collection box 6 for collecting metal debris is fixedly connected to the outer wall of the machine tool 1, and a lifting component 7 for driving the scraper 2 to move vertically is installed on the top of the push block 3.

[0021] Embodiment 2:

[0022] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the lifting assembly 7 includes a movable rod 9 for driving the scraper 2 to move up and down, a sleeve 8 is fixedly connected to the top of the push block 3 for allowing the movable rod 9 to move only vertically up and down, and sockets 10 are provided on the left and right sides of the sleeve 8. The inner wall of the socket 10 is slidably connected with a plug plate 11 for supporting the movable rod 9, the outer wall of the plug plate 11 is sleeved with a compression spring 13 for pushing the plug plate 11, and one end of the plug plate 11 is fixedly connected with a circular plate 12 for fixing the compression spring 13.

[0023] Embodiment three:

[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 1 As shown, a through groove for placing a scraper 2 is opened on the top of the machine tool 1, and the depth of the through groove is the same as the height of the scraper 2. When the CNC machine tool is processing, the scraper 2 can be inserted into the through groove to make the top of the machine tool 1 flat and beautiful, and will not affect the operation of the CNC machine tool.

[0025] To sum up, when it is necessary to clean the debris on the machine tool 1, the staff will move the scraper 2 out of the through slot, and the scraper 2 will move upward with the movable rod 9. When the height of the movable rod 9 exceeds the height of the insert plate 11, the compression spring 13 will push the insert plate 11 to move, and the insert plate 11 will support the movable rod 9. At the same time, the bottom of the scraper 2 will contact the top of the machine tool 1. At this time, the staff will turn on the motor 5, and the motor 5 will drive the screw rod 4 to rotate. The screw rod 4 will move the push block 3 through the thread, and the push block 3 will drive the scraper 2 to push the metal debris on the top of the machine tool 1 into the inside of the collection box 6, so as to facilitate the staff to collect and organize the metal debris. At the same time, the scraper 2 cleans the metal debris without the need for the staff to manually collect the debris;

[0026] After the metal debris on the machine tool 1 is cleaned, the staff controls the motor 5 to rotate the screw 4 in the opposite direction, so that the scraper 2 is reset. After the screw 4 reaches the top of the through groove, the staff grasps the circular plate 12 to pull the plug 11 out of the socket 10, so that the plug 11 will not support the movable rod 9. The scraper 2 will fall into the through groove without support. Since the height of the scraper 2 is the same as the depth of the through groove, the top of the machine tool 1 is flat and has no protrusions, which not only does not affect the operation of the CNC machine tool but also looks beautiful.
