[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a coolant recovery device for a CNC milling machine. Figure 1-3 A coolant recovery device for a numerically controlled milling machine comprises a milling machine body 1, two groups of guide grooves 2 are provided at the bottom of the inner cavity of the milling machine body 1, guide plates 3 are fixedly connected to the bottom of the inner cavity of the two groups of guide grooves 2 by bolts, chip collecting parts are provided at one end of the two groups of guide plates 3, and the chip collecting parts are arranged inside the guide grooves 2, a recovery box 4 is fixedly connected to one side of the milling machine body 1 by bolts, a liquid outlet joint 6 is fixedly connected to one side of the recovery box 4 by bolts, and a DC motor 5 is fixedly connected to the side of the recovery box 4 near the liquid outlet joint 6 by bolts, A cleaning piece is provided at one end of the DC motor 5, and the cleaning piece is arranged inside the recycling box 4. The side of the recycling box 4 away from the DC motor 5 is rotatably connected with a sealing cover 12 through a rotating shaft. The chip collecting piece includes a chip collecting box 13, a limiting rod 14 and a lifting handle 15. The two groups of guide grooves 2 are both provided with chip collecting boxes 13. The bottoms of the two groups of chip collecting boxes 13 are both fixedly connected with two groups of limiting rods 14. The surfaces of the two groups of limiting rods 14 are both plugged into the bottom of the inner cavity of the guide groove 2. The tops of the two groups of chip collecting boxes 13 are both fixedly connected with the lifting handles 15 by bolts.
[0020] By adopting the above technical solution, two groups of guide grooves 2 are opened at the bottom of the inner cavity of the milling machine body 1, so that the coolant used by the milling machine body 1 can flow into the guide groove 2, and the guide plates 3 in the guide groove 2 are inclined at corresponding angles, so that the coolant can flow toward the chip box 13 and the recycling box 4. Because the iron chips remaining in the coolant are heavy, they are generally precipitated to the bottom of the coolant. Because its two groups of chip boxes 13 are lower than the lowest point of the guide plate 3, the chips and iron chips flowing with the coolant can enter the chip box 13, and the coolant can be filtered through the chip box 13 and then enter the recycling box 4, and can enter the recycling box again through the cleaning piece. 4 is filtered so that a cleaner coolant can be obtained. After the coolant has been filtered for multiple times, the coolant can be recovered through its liquid outlet joint 6, liquid storage container equipment related to the connector, etc., and the chip collecting box 13 can be taken out by pulling the lifting handles 15 on the two sets of chip collecting boxes 13, so that the iron chips and other impurities collected inside can be collected and processed conveniently. The limiting rod 14 is provided to facilitate the insertion of the chip collecting box 13 into the guide groove 2 to ensure its stability during use. At the same time, the DC motor 5 is used in conjunction with its related cleaning parts to collect and process the iron chips and other impurities remaining in the recovery box 4 after filtering again.
[0021] Reference Figure 1 and Figure 2 , the cleaning parts include a fine filter plate 7, a threaded rod 8, a threaded sleeve 9, a scraper 10 and a coarse filter plate 11, the inner cavity side wall of the recovery box 4 is fixedly connected with two groups of coarse filter plates 11 by bolts, the inner cavity side wall of the recovery box 4 is fixedly connected with the fine filter plate 7 by bolts, the DC motor 5 is fixedly connected with the threaded rod 8 through the output shaft, and the threaded rod 8 is arranged above the two groups of coarse filter plates 11 and the fine filter plate 7, the end of the threaded rod 8 away from the DC motor 5 rotates through the recovery box 4, and the end of the threaded rod 8 passing through the recovery box 4 is rotatably connected to the inner cavity side wall of the recovery box 4 through a rotating shaft, the surface of the threaded rod 8 is threadedly connected with a threaded sleeve 9, the bottom of the threaded sleeve 9 is fixedly connected with a scraper 10 by bolts, and the bottom of the scraper 10 fits the top of the fine filter plate 7;
[0022] By adopting the above technical solution, when the coolant flows into the recovery box 4, it can be filtered by two groups of coarse filter plates 11, and then after entering the recovery box 4, some smaller iron filings and impurities are filtered by the fine filter plate 7. It can be seen from the attached figure that there are multiple groups of circular holes on the fine filter plate 7, but there are also smaller filter holes in the circular holes. Because the filter holes are small, it is inconvenient to show them as a whole. However, the filter holes of the fine filter plate 7 are smaller than the filter holes of the coarse filter plate 11, and can filter smaller impurities such as iron filings. The fine filter plate 7 is inclined at a corresponding angle so that the filtered iron filings and impurities slide toward the sealing cover 12. When the coolant flows into the bottom of the recovery box 4 and is lower than the fine filter plate 7, after the recovery and collection of the coolant is completed, the sealing cover 12 can be opened, and the DC motor 5 can be used to Output, drive its threaded rod 8 to rotate, so that its threaded sleeve 9 drives the scraper 10 at the bottom to move in contact with the top of the fine filter plate 7, and scrapes the iron filings impurities remaining on its surface to the sealing cover 12, so as to facilitate the centralized collection and treatment of the iron filings impurities filtered out by it, and the reverse output rotation of the DC motor 5 can drive the threaded rod 8 to rotate in the reverse direction, so that the scraper 10 is reset. The DC motor 5 can choose the servo motor HBS57 type. The DC motor 5 can rotate in different directions, because the structure and working principle of the DC motor 5 determine that it can realize bidirectional rotation. The DC motor 5 can change the rotation direction by changing the direction of the current, and the control of the current direction can be achieved by a controller or an inverter. Because its DC motor 5 is a prior art device, it will not be described in detail here.
[0023] The implementation principle of a coolant recovery device for a CNC milling machine according to an embodiment of the present application is as follows: two groups of guide grooves 2 are opened at the bottom of the inner cavity of the milling machine body 1 to facilitate the coolant used by the milling machine body 1 to flow into the guide grooves 2, and the guide plates 3 in the guide grooves 2 are inclined at corresponding angles so that the coolant can flow toward the chip box 13 and the recovery box 4. Since the iron chips and swarfs remaining in the coolant are heavier, they are generally precipitated to the bottom of the coolant. Since the two groups of chip boxes 13 are lower than the lowest point of the guide plates 3, the chips and swarfs flowing with the coolant can enter the chip box 13. When the coolant flows into the recovery box 4, the coolant can be filtered by two groups of coarse filter plates 11, and then after entering the recovery box 4, some of the coolant can be filtered through its fine filter plates 7. Smaller impurities such as iron filings can be filtered out. As can be seen from the attached figure, there are multiple groups of circular holes on the fine filter plate 7, but there are also smaller filter holes in the circular holes. Because the filter holes are small, it is inconvenient to show them as a whole. However, the filter holes of the fine filter plate 7 are smaller than the filter holes of the coarse filter plate 11, and can filter out smaller impurities such as iron filings. The fine filter plate 7 is inclined at a corresponding angle so that the iron filings impurities filtered out slide toward the sealing cover 12. When the coolant flows into the bottom of the recovery box 4 and is lower than the fine filter plate 7, after the coolant is recovered and collected, the sealing cover 12 can be opened, and the output of the DC motor 5 is used to drive the threaded rod 8 to rotate, so that the threaded sleeve 9 drives the scraper 10 at the bottom to move against the top of the fine filter plate 7 to remove the residue on its surface. The iron filings impurities are scraped to the sealing cover 12, which is convenient for centralized collection and treatment of the filtered iron filings impurities, and the reverse output rotation of the DC motor 5 can drive the threaded rod 8 to rotate in the reverse direction, so that the scraper 10 is reset. The DC motor 5 can use the servo motor HBS57 type. The DC motor 5 can rotate in different directions, because the structure and working principle of the DC motor 5 determine that it can achieve bidirectional rotation. The DC motor 5 can change the direction of rotation by changing the direction of the current, and the control of the current direction can be achieved by a controller or an inverter. Because its DC motor 5 is a prior art device, it will not be described in detail here. After the coolant is filtered multiple times, it can be passed through its liquid outlet joint 6, connector-related liquid storage container equipment, etc. , and its coolant is recovered, and the chip collecting box 13 can be taken out by pulling the lifting handles 15 on the two sets of chip collecting boxes 13, so that the iron chips and other impurities collected inside can be collected and processed conveniently, and the limiting rod 14 is provided to facilitate the insertion of the chip collecting box 13 into the guide groove 2 to ensure its stability during use, and at the same time, by using the DC motor 5 and its related cleaning parts, it can enter the recovery box 4 to filter the remaining iron chips and other impurities again for collection and processing. The overall use and operation are simple, and the iron chips and other impurities in the coolant can be filtered and separated in time, and the iron chips and other impurities and the coolant can be centrally recovered and processed separately, thereby effectively improving the recovery efficiency of the coolant and the quality of the coolant.
