When CNC machine tools are used to process workpieces, the workpieces will produce a large amount of iron filings, which will adhere to the inside of the machine body. In order to prevent the workpieces from being affected, it is necessary to clean the inside of the machine body regularly to flush out the iron filings and ensure the integrity of the product.
[0003] At present, most of the iron filings are cleaned by using an air gun. Each CNC machine tool is equipped with an air gun specifically used to blow away the iron filings. Some large iron wires can be blown directly into the waste chip box, but some very small iron filings will fly around when blown by the gas, and it is easy to fly into the eyes of the staff, causing harm to the staff and prone to danger. Therefore, we propose a CNC machine cleaning device to solve the above problems. Utility Model Content

[0026] Example
[0027] Reference Figure 1-Figure 4The utility model provides a technical solution: a CNC machine tool cleaning device, including a body 1 and a cleaning mechanism 3, a hollow bin 2 is installed at the bottom of the body 1, the cleaning mechanism 3 includes a liquid collecting bin 31, the liquid collecting bin 31 is installed inside the hollow bin 2, a partition 311 is fixedly installed inside the liquid collecting bin 31, a water pump 32 is fixedly installed on the outer surface of the liquid collecting bin 31, a water inlet end and a water outlet end of the water pump 32 are respectively installed with water pipes 321, a bamboo tube 33 is installed on one end of one of the water pipes 321, the bamboo tube 33 is stably installed inside the body 1, and a filter plate 34 is movably installed inside the liquid collecting bin 31.
[0028] In a preferred embodiment, two water pumps 32 are provided and are respectively installed at the two ends of one side of the liquid collecting bin 31. A water pipe 321 is installed on each water pump 32. The water pipe 321 on the water inlet end of the water pump 32 is arranged inside the liquid collecting bin 31. The device provides two water pumps 32, one for extracting clean water to flush the iron filings inside the machine body 1, and the other water pump 32 extracts cutting fluid so that the outer surface of the workpiece is sprayed with cutting fluid, thereby reducing the temperature generated by the workpiece during processing and improving the processing accuracy of the workpiece.
[0029] In a preferred embodiment, a positioning block 4 is fixedly installed inside the machine body 1, and a bamboo tube 33 passes through the interior of the positioning block 4. A large amount of iron filings will be generated when the machine body 1 processes the workpiece. A large amount of iron filings will adhere to the inside of the machine body 1, which will affect the processing of the workpiece. In order to facilitate the cleaning of the iron filings, a bamboo tube 33 is installed inside the machine body 1, and the bamboo tube 33 is installed on the positioning block 4. The bamboo tube 33 can be stably controlled to flush the iron filings, and the iron filings can be flushed out from the inside of the machine body 1 to ensure normal processing of the workpiece.
[0030] In a preferred embodiment, a sliding groove 5 is provided on the inner wall of one side of the liquid collecting bin 31, and a slider 6 is provided inside the sliding groove 5. The slider 6 is fixedly connected to the filter plate 34, and the upper surface of the filter plate 34 is fixedly connected to the lifting rod 7. After flushing the iron filings, the iron filings will flow into the clean water bin 8 together with the water. In order to prevent the iron filings from being sucked into the water pump 32 and causing damage to the water pump 32, a removable filter plate 34 is installed inside the clean water bin 8 to filter the iron filings, and the filter plate 34 is fixedly connected to the slider 6 to facilitate the removal of the filter plate 34 and clean up the iron filings on the filter plate 34 to meet the needs of use.
[0031] To prevent the cutting fluid from being diluted by water, the interior of the liquid collecting bin 31 is divided into two by a partition 311, one of the spaces is set as a clean water bin 8, and the other space is set as a cutting fluid bin 9. A material receiving bin 10 is installed on the top of the cutting fluid bin 9, and a removable sealing plug 11 is installed on the top of the material receiving bin 10. The interior of the liquid collecting bin 31 is divided into two by the partition 311, and clean water and cutting fluid are collected separately so that they can be used independently to meet the needs of use.
[0032] When the workpiece is being processed, the cutting fluid will be controlled to spray out to reduce the temperature of the workpiece. Therefore, the cutting fluid is relatively expensive to use. In order to reduce the number of times the staff adds cutting fluid, a diversion mechanism 12 is installed inside the liquid collecting bin 31. The diversion mechanism 12 includes a filter 121, a sealing plate 122 and a liquid level sensor 123. The liquid level sensor 123 is fixedly installed on the outer surface of the liquid collecting bin 31. The probe on the liquid level sensor 123 is set inside the liquid collecting bin 31. The liquid level sensor 123 is electrically connected to the PLC controller 13, and the PLC controller 13 is electrically connected to the alarm light 14. Filters 121 are respectively provided inside the clean water bin 8 and the cutting fluid bin 9. The filter 121 is set in the shape of L. A through hole is opened on one side of the partition 311, and a sealing plate 122 is rotatably installed outside the through hole and inside the cutting fluid bin 9.
[0033] During use, when the liquid inside the cutting fluid tank 9 is lower than the position of the sealing plate 122, it means that the amount of cutting fluid has decreased. At this time, the liquid inside the clean water tank 8 will push the sealing plate 122 to rotate, and pass through the partition 311 to flow into the cutting fluid tank 9, mix with the cutting fluid, and increase the amount of cutting fluid, thereby ensuring that the cutting fluid continues to be sprayed out for use, effectively replacing manual work to pick up the cutting fluid and pour it into the cutting fluid tank 9, saving time, reducing the labor intensity of personnel, and meeting usage requirements.
[0034] Specifically, the working process or working principle of a CNC machine cleaning device is as follows: Currently, most of the iron filings are cleaned by blowing with an air gun. Each CNC machine tool is equipped with an air gun specifically used to blow away the iron filings. Some large iron wires can be blown directly into the waste chip box, but some very small iron filings will fly around when blown by the gas, and it is easy to fly into the eyes of the staff, causing harm to the staff and prone to danger. Therefore, this device is designed to solve this problem.
[0035] When the external power supply is connected and the workpiece is processed by the CNC machine tool, no large iron wire will be generated, but some small iron filings will be generated. As the number of workpieces processed increases, the iron filings attached to the inside of the machine body 1 will also increase. When the iron filings increase, the whirlwind generated by the rotation of the machine tool spindle can easily spin the iron filings away. When the workpiece is running at high speed, it is easy to be hit by the flying iron filings, causing damage to the outer surface, thereby affecting the quality of the workpiece. Therefore, after processing a certain number of workpieces, the iron filings attached to the inside of the machine body 1 can be removed to prevent affecting the workpiece.
[0036] By turning on the water pump 32 corresponding to the clean water tank 8, the clean water entering the clean water tank 8 through the water pump 32 is extracted, and transported to the inside of the bamboo tube 33 through the water pipe 321 on the water outlet end of the water pump 32, and the clean water is sprayed out through the bamboo tube 33. Since the bamboo tube 33 can be bent and rotated at will and can maintain a certain state, when flushing iron filings, the staff can manually operate the bamboo tube 33 and continuously adjust the water spraying position to flush away the attached iron filings. The flushed iron filings will flow back to the inside of the clean water tank 8, thereby flushing away the iron filings attached to the inside of the machine body 1 and avoiding affecting the workpiece processing.
[0037] In order to prevent a large amount of iron filings from falling to the inner bottom of the clean water bin 8, a filter plate 34 is installed inside the clean water bin 8. The filter plate 34 will filter the iron filings to prevent them from falling to the inner bottom of the clean water bin 8, thereby preventing the iron filings from being sucked into the water pump 32 and causing damage to the water pump 32. After each day's work, the filter plate 34 is taken out from the clean water bin 8, and the iron filings are cleaned off the filter plate 34 to prevent them from accumulating on the filter plate 34.
[0038] When the machine body 1 is processing the workpiece, the cutting fluid will be used to spray the workpiece to reduce the high temperature generated during the processing of the workpiece. The device uses a mixture of cutting fluid dry powder and water to form a cutting fluid. The cutting fluid is continuously used and the liquid volume will gradually decrease. When the liquid volume inside the cutting fluid tank 9 is lower than the position of the sealing plate 122 and the liquid volume inside the clean water tank 8 is higher than the sealing plate 122, the water inside the clean water tank 8 will flow to the inside of the cutting fluid tank 9, thereby increasing the amount of cutting fluid, reducing the number of times the cutting fluid is manually added, saving time, and reducing the labor intensity of the staff.
[0039] Since the sealing plate 122 is arranged inside the cutting fluid bin 9, the water inside the clean water bin 8 can flow into the inside of the cutting fluid bin 9, while the liquid inside the cutting fluid bin 9 cannot flow into the inside of the clean water bin 8, which can ensure the use of the cutting fluid. Since a large amount of water from the clean water bin 8 flows into the inside of the cutting fluid bin 9, the cutting fluid will be diluted. At this time, the staff can remove the sealing plug 11, and the cutting fluid dry powder inside the receiving bin 10 will fall into the cutting fluid bin 9 and mix with the liquid for sustainable use. When the liquid inside the clean water bin 8 and the cutting fluid bin 9 is reduced, the liquid level sensor 123 detects that the liquid level inside the two bins reaches the lowest position, and the PLC controller 13 controls the alarm light 14 to alarm, thereby reminding the staff to add liquid to the two bins, first add liquid to the cutting fluid bin 9, and then add liquid to the clean water bin 8, so as to prevent a large amount of clean water from flowing into the cutting fluid bin 9, causing the cutting fluid concentration to be too thin, affecting the use effect.
[0040] While cleaning the iron filings attached to the inside of the machine body 1, the device can also add liquid to the cutting fluid tank 9 to ensure sufficient cutting fluid, reduce the number of times the staff adds cutting fluid, save time, reduce the labor intensity of the staff, and improve work efficiency.
[0041] It should be noted that the water pump 32, liquid level sensor 123, PLC controller 13 and alarm light 14 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
