Technical Field

[0001] The utility model relates to the technical field of cutting machine tools, in particular to a cutting fluid recovery bin for a numerically controlled machine tool. Background Art

[0002] In production and processing, cutting fluid is needed to lubricate, cool and clean the parts being cut. Most of the used cutting fluids contain a large amount of impurities such as metal chips, floating oil, particulate matter, etc. Therefore, the used cutting fluid generally needs to be recovered and separated before being recycled to reduce enterprise costs and save resources.

[0003] Existing cutting fluid separation methods often remove impurities through filter filtration and centrifugal filtration. In the existing centrifugal filtration method, the purified cutting fluid is discharged and the impurities remain in the centrifugal cylinder. In order to ensure the filtering effect of the centrifugal cylinder, the centrifugal cylinder needs to be disassembled and the impurities inside are cleaned after each use. Frequent disassembly and cleaning is undoubtedly troublesome. Utility Model Content

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a cutting fluid recovery bin for a numerical control machine tool, including a recovery bin body 1 and a centrifugal separation cylinder 2 rotatably arranged in the recovery bin body 1. A cleaning component 3 is arranged in the recovery bin body 1. The cleaning component 3 includes a scraper 301 that can be telescopically arranged in the centrifugal separation cylinder 2. The scraper 301 has two working states: in the initial working state, it does not contact the centrifugal separation cylinder 2; in the cleaning working state, it extends and expands to abut against the centrifugal separation cylinder 2.

[0021] Specifically, by arranging a telescopic scraper 301 in the centrifugal separation cylinder 2, after the centrifugal separation cylinder 2 is used, the scraper 301 is extended to abut against the inner wall of the centrifugal separation cylinder 2. As the centrifugal separation cylinder 2 rotates, the inner wall of the centrifugal separation cylinder 2 can be cleaned. During the specific cleaning process, in order to further improve the cleaning effect, it can be rinsed with water, thus avoiding the situation of disassembly and cleaning. When using centrifugal force to clean the cutting fluid, the centrifugal separation cylinder 2 is retracted and does not abut against the inner wall of the centrifugal separation cylinder 2 to ensure that it will not interfere with the centrifugal separation cylinder 2.

[0022] Preferably, the specific height and shape of the scraper 301 are not limited herein. It can be set as annular or rectangular, as long as it can clean the inner wall of the centrifugal separation cylinder 2. In order to ensure the cleaning effect of the scraper 301, a brush can be arranged on the side of the scraper 301 opposite to the inner wall of the centrifugal separation cylinder 2 to improve the cleaning effect.

[0023] Please refer to Figure 2 and Figure 4 , to facilitate driving the scraper 301 to expand and contract, the structure in the cleaning component 3 needs to be further disclosed. The cleaning component 3 further includes a mounting frame 8 slidably arranged in the recovery bin body 1. A telescopic block 302 connected to one side of the scraper 301 is slidably connected to the mounting frame 8. A connecting block 303 is rotatably connected to the telescopic block 302. The other end of the connecting block 303 is rotatably connected to a vertically movable nut 304. When the nut 304 moves to a certain position, it drives the scraper 301 to move horizontally.

[0024] Specifically, driving the nut 304 downward increases the angle between the connecting block 303 and the nut 304 continuously. When it reaches 90 degrees, the scraper 301 is in a fully extended state, and at this time, the scraper 301 is in close contact with the inner wall of the centrifugal separation cylinder 2.

[0025] Please refer to Figure 3 and Figure 4 For the convenience of driving the nut 304 and controlling the cleaning range of the scraper 301, a rotating shaft 4 is rotatably connected in the recycling bin body 1. A threaded groove 5 is provided on the rotating shaft 4, and the nut 304 is threadedly connected to the rotating shaft 4. The top of the rotating shaft 4 is connected to a servo motor 6 that drives the rotation of the rotating shaft 4. One side of the servo motor 6 is connected to an electric telescopic rod 7 for adjusting the height of the scraper 301, and the electric telescopic rod 7 is connected in the recycling bin body 1.

[0026] Preferably, to ensure the stability of the movement of the nut 304 and guide and limit the movement of the nut 304, a guide rod is connected in the mounting frame 8 so that the nut 304 is slidably connected to the guide rod.

[0027] Specifically, starting the servo motor 6 drives the rotation of the rotating shaft 4. At this time, the threaded groove 5 provided on the rotating shaft 4 can drive the nut 304 to move vertically up and down by means of screw drive, and the provided electric telescopic rod 7 facilitates adjusting the cleaning range of the scraper 301.

[0028] Refer to Figure 4 , a connecting spring 9 is connected in the mounting frame 8. The other end of the connecting spring 9 is connected to a fixing plate, and the fixing plate is connected to the telescopic block 302. The provided connecting spring 9 facilitates the scraper 301 to rebound and return to its original position.

[0029] Refer to Figure 2 , a driven gear ring 12 is connected to the centrifugal separation cylinder 2. A driving gear 10 is meshed and connected to one side of the driven gear ring 12. The top of the recycling bin body 1 is connected to a driving motor 11. The driving end of the driving motor 11 is connected to a connecting shaft, and one end of the connecting shaft extends into the recycling bin body 1 and is connected to the driving gear 10. Starting the driving motor 11 drives the rotation of the driving gear 10, and then the centrifugal separation cylinder 2 can be driven to rotate by means of the driven gear ring 12, so as to remove impurities from the cutting fluid in the centrifugal separation cylinder 2.

[0030] Please continue to refer to Figure 2 , a cutting fluid inlet pipe and a cutting fluid outlet pipe are connected to one side of the recycling bin body 1. A sedimentation tank 13 is provided in the recycling bin body 1. A waste discharge pipe 14 is connected to the bottom of the recycling bin body 1, and the position of the waste discharge pipe 14 corresponds to that of the sedimentation tank 13. The provided sedimentation tank 13 is convenient for sedimenting impurities, the provided waste discharge pipe 14 corresponding to the sedimentation tank 13 is convenient for discharging the sedimented impurities, and the provided cutting fluid inlet pipe and cutting fluid outlet pipe are convenient for feeding and discharging.

[0031] Working principle: When it is necessary to clean the centrifugal separation cylinder 2:

[0032] First, start the driving motor 11 to drive the driving gear 10 to rotate. Subsequently, the driven gear ring 12 can drive the centrifugal separation cylinder 2 to rotate, so as to remove impurities from the cutting fluid in the centrifugal separation cylinder 2. After the centrifugal separation cylinder 2 is used up, the scraper 301 is extended to contact the inner wall of the centrifugal separation cylinder 2. As the centrifugal separation cylinder 2 rotates, the inner wall of the centrifugal separation cylinder 2 can be cleaned. The driving nut 304 moves downward, and the angle between the connecting block 303 and the nut 304 is continuously increased. When it reaches 90 degrees, the scraper 301 is in a fully extended state. At this time, the scraper 301 is in close contact with the inner wall of the centrifugal separation cylinder 2. This setting can avoid the situation of disassembly and cleaning. When cleaning the cutting fluid by centrifugal force, the centrifugal separation cylinder 2 is retracted and does not contact the inner wall of the centrifugal separation cylinder 2 to ensure that the centrifugal separation cylinder 2 will not be interfered.
