[0002] In the field of mechanical manufacturing, CNC milling is widely used in the cutting process of various parts due to its advantages of high precision and high efficiency. However, in the actual processing, the cutting tool generates a large amount of metal chips when cutting the workpiece. At the same time, the cutting fluid sprayed to reduce the cutting temperature and extend the tool life often carries chips and splashes around the equipment during the cutting fluid spraying process. This not only pollutes the processing environment, but the scattered sharp chips can also pose a safety hazard to the operators. In addition, the subsequent manual cleaning process often takes a lot of time, which increases the labor intensity of the personnel's daily work. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic chip collection device for CNC milling, which has the function of automatically collecting chips, reducing the labor intensity of manual cleaning, and bringing great convenience to the daily work of personnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic chip collection device for CNC milling, comprising a base, a CNC machine tool fixedly mounted on the top of the base, a liquid collection tank fixedly mounted at the middle of the bottom of the base cavity, a collection frame placed on the top of the liquid collection tank, a filter plate fixedly mounted in the inner cavity of the collection frame, guide platforms fixedly mounted on the upper ends of both sides of the base cavity, a scraper slidably connected to the upper end of the guide platform, a moving rod fixedly mounted on the back of the scraper, a fixed frame fixedly mounted on the upper end of the back of the base, a servo motor fixedly mounted on the lower end of the left side of the outer surface of the fixed frame, a bidirectional ball screw fixedly mounted on the output end of the servo motor, the right side of the bidirectional ball screw being movably connected to the lower end of the right side of the inner cavity of the fixed frame via a bearing, ball nuts being drivenly connected to both ends of the bidirectional ball screw, a drive plate fixedly mounted on the surface of the ball nuts, a guide groove being opened at the upper end of the drive plate, and the surface of the moving rod being slidably connected to the upper end of the guide groove.

[0005] As a preferred embodiment, guide rods are fixedly installed at both ends of the back of the base and at both ends of the back of the fixed frame, and the two ends of the movable rod are slidably connected to the surface of the guide rods.

[0006] As a preferred embodiment, a support slide rod is fixedly installed between the two ends of the bottom of the fixed frame, and the lower end of the drive plate is slidably connected to the surface of the support slide rod.

[0007] As a preferred embodiment, protective inclined plates are fixedly installed at both ends of the inner cavity of the base and above the scraper.

[0008] As a preferred embodiment, limiting plates are fixedly installed on the upper ends of both sides of the outer surface of the liquid collection tank, and the lower end of the outer surface of the collection frame is slidably connected to the surface of the limiting plates.

[0009] As a preferred embodiment, a drain pipe is fixedly installed at the lower end of the back side of the liquid collection tank.

[0010] As a preferred embodiment, a fixing plate is fixedly connected to the upper end of the front surface of the collection frame, and an installation bolt is movably inserted through the upper end of the fixing plate. The surface of the installation bolt is threadedly connected to the upper end of the front surface of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the inclusion of a base, guide platform, collection frame, filter plate, scraper, and drive mechanism, automatically collects and separates debris and cutting fluid generated during CNC milling. During machining, debris and cutting fluid are guided to the collection frame via the guide platform and filtered and separated by the filter plate. The debris remains in the collection frame, while the cutting fluid flows into a collection tank for easy recycling. After machining, a servo motor drives a bidirectional ball screw to rotate, which, through the ball nut, drive plate, and guide groove, drives a moving rod and scraper to move along the inclined surface of the guide platform, thoroughly scraping any remaining debris into the collection frame. Subsequently, personnel simply need to pull the collection frame from the top of the collection tank and empty the debris to complete the cleaning process. The overall operation is convenient and quick, significantly reducing the labor intensity of operators and improving cleaning efficiency. Attached Figure Description

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.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figures 1-4As shown, this utility model provides an automatic chip collection device for CNC milling, including a base 2, a CNC machine tool 1 fixedly installed on the top of the base 2, a liquid collection tank 3 fixedly installed at the middle of the bottom of the inner cavity of the base 2, a collection frame 4 placed on the top of the liquid collection tank 3, a filter plate 8 fixedly installed in the inner cavity of the collection frame 4, a guide platform 7 fixedly installed on the upper ends of both sides of the inner cavity of the base 2, a scraper 11 slidably connected to the upper end of the guide platform 7, a moving rod 12 fixedly installed on the back of the scraper 11, and a fixed rod 12 on the upper end of the back of the base 2. A fixed frame 9 is provided, and a servo motor 16 is fixedly installed on the lower left side of the outer surface of the fixed frame 9. A bidirectional ball screw 17 is fixedly installed on the output end of the servo motor 16. The right side of the bidirectional ball screw 17 is movably connected to the lower right side of the inner cavity of the fixed frame 9 through a bearing. Both ends of the bidirectional ball screw 17 are connected to ball nuts 18. A drive plate 19 is fixedly installed on the surface of the ball nuts 18. A guide groove 21 is opened at the upper end of the drive plate 19. The surface of the moving rod 12 is slidably connected to the upper end of the guide groove 21.

[0023] In this technical solution, during the milling process of the CNC machine tool 1, the generated chips can flow into the base 2 along with the spray of cutting fluid. The guide platforms 7 at both ends of the base 2 guide the flowing cutting fluid and chips, causing them to collect in the collection frame 4. Under the action of the filter plate 8, the chips in the cutting fluid are filtered and flow into the collection tank 3, thus separating and collecting the chips and cutting fluid. After the milling process is completed, the servo motor 16 is started by the external controller to drive the bidirectional roller. While the ball screw 17 rotates, it drives the two sets of ball nuts 18 and the drive plate 19 to move closer to each other. As the drive plate 19 moves, it pushes the moving rod 12 through the guide groove 21. As the moving rod 12 moves, it drives the scraper 11 to move along the inclined surface of the guide platform 7, which can scrape the debris remaining on the top of the guide platform 7 into the collection frame 4. Afterwards, the personnel only need to pull the collection frame 4 out from the top of the liquid collection tank 3 and pour out the debris to complete the debris cleaning work, which greatly facilitates the debris cleaning work.

[0024] It should be noted that both the surface of the bidirectional ball screw 17 and the guide groove 21 are coated with grease, and personnel can perform regular maintenance as needed.

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, guide rods 13 are fixedly installed at both ends of the back of the base 2 and both ends of the back of the fixed frame 9. The two ends of the moving rod 12 are slidably connected to the surface of the guide rods 13. A support slide rod 20 is fixedly installed between the two ends of the bottom of the fixed frame 9. The lower end of the drive plate 19 is slidably connected to the surface of the support slide rod 20. Protective inclined plates 14 are fixedly installed at both ends of the inner cavity of the base 2 and above the scraper 11. Limiting plates 15 are fixedly installed at the upper ends of both sides of the outer surface of the liquid collection tank 3. The lower end of the outer surface of the collection frame 4 is slidably connected to the surface of the limiting plate 15. A drain pipe 10 is fixedly installed at the lower end of the back of the liquid collection tank 3. A fixing plate 5 is fixedly connected to the upper end of the front surface of the collection frame 4. A mounting bolt 6 is movably inserted into the upper end of the fixing plate 5. The surface of the mounting bolt 6 is threadedly connected to the upper end of the front surface of the base 2.

[0027] In this technical solution, the guide rod 13 is used to support and guide both ends of the moving rod 12, preventing the moving rod 12 from deviating during movement. The support slide rod 20 is used to support and guide the drive plate 19, preventing the drive plate 19 from tilting during movement. The protective plate 14 is used to protect the area above the guide rod 13, preventing debris from falling to the outside through the gaps around the guide rod 13. The limiting plate 15 is used to limit the two sides of the collection frame 4. The drain pipe 10 is used to connect with the external recycling pipeline, so as to recycle the cutting fluid in the collection tank 3. The fixing plate 5 and the mounting bolts 6 are used to install and fix the collection frame 4 to the base 2.

[0028] It should be noted that the guide bar 13 and the guide platform 7 are set in parallel.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model.
