Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of machining cleaning, and particularly to a cleaning device for machining. Background Art
[0002] Machining is a way of processing parts, which processes raw materials to meet the final required specifications and has relatively high precision and quality. The key part of machining is the machine tool, which is a machine used to process raw materials and is used in multiple aspects such as cutting, drilling, milling, turning, high-speed milling, and numerical control machining. During the machining process, cutting fluid is usually used to cool, lubricate, clean waste chips, and prevent rust on the tool and the workpiece.
[0003] During the machining process, cutting fluid is usually used to clean the waste chips cut out. After cleaning, the cutting fluid needs to filter the waste chips so that the cutting fluid can be recycled. At the same time, the cutting fluid will also mix with some rust-proof oil of the part itself, resulting in the generation of floating oil. The floating oil will cause problems such as the deterioration and odor of the cutting fluid, corrosion, foaming, and skin allergies of the operator. Long-term use of the cutting fluid will reduce the pH value of the cutting fluid, affecting the rust prevention of the tool and the workpiece, and at the same time, it will also cause a large number of microorganisms to breed, affecting the use effect of the cutting fluid.

Specific embodiments
[0016] 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.
[0017] Example 1, please refer to Figures 1-9 , the present invention provides a technical solution: a cleaning device for machining, including a CNC machine tool 1. There are a machining chamber 2 and a motor chamber 3 opened in the CNC machine tool 1. A machining part 4 is arranged in the machining chamber 2. The machining part 4 is fixedly connected to the inner wall of the machining chamber 2 and is used for machining parts. Below the machining part 4, there are a first stainless steel plate 5 and a second stainless steel plate 6. Both the first stainless steel plate 5 and the second stainless steel plate 6 are fixedly connected to the inner wall of the machining chamber 2. Below the first stainless steel plate 5 and the second stainless steel plate 6, there is a liquid storage chamber 7 for storing cutting fluid. The liquid storage chamber 7 is located below the machining chamber 2. The upper side of the machining part 4 is fixedly connected with a cutting fluid nozzle 8, which is used to spray cutting fluid when machining parts, cool the tool, and at the same time clean the generated waste chips. The cutting fluid nozzle 8 is connected to a hydraulic pump 9 through a pipeline. The hydraulic pump 9 is fixedly connected to the bottom side of the inner wall of the motor chamber 3. The input end of the hydraulic pump 9 is communicated with the liquid storage chamber 7 through a pipeline. A conveyor belt 10 is arranged between the first stainless steel plate 5 and the second stainless steel plate 6 and is used to discharge the waste chips generated by machining. Both the left and right ends of the conveyor belt 10 are connected to brackets 11 through bearings. The bracket 11 on the left side of the conveyor belt 10 is fixedly connected to the bottom inner wall of the liquid storage chamber 7. The bracket 11 on the right side of the conveyor belt 10 is fixedly connected to the outer wall on the right side of the CNC machine tool 1; Refer to Figure 1 、Refer to Figure 4, the output end of the conveyor belt 10 penetrates through the outer shell on the right side of the numerical control machine tool 1. One end of the transmission shaft at the output end of the conveyor belt 10 penetrates through the left support 11 and is fixedly connected to a driving motor 12. The driving motor 12 is fixedly connected to the outer wall on the right side of the numerical control machine tool 1. Both sides of the conveyor belt 10 are fixedly connected with barrier belts 27 for blocking and guiding the flow direction of the cutting fluid; Reference Figure 8 , the height of one side of the input end of the conveyor belt 10 is lower than that of the output end side of the conveyor belt 10, so that the cutting fluid on the conveyor belt 10 flows back to the liquid storage chamber 7 from the input end of the conveyor belt 10 under the action of gravity; Reference Figure 7 , a filter plate 13 is arranged above one side of the input end of the conveyor belt 10. The filter plate 13 is located between the first stainless steel plate 5 and the second stainless steel plate 6. Both sides of the filter plate 13 are respectively fixedly connected to the first stainless steel plate 5 and the second stainless steel plate 6. The bottom side of the filter plate 13 is in direct contact with the upper belt surface of the conveyor belt 10, and is used for filtering waste chips and part of oil substances in the cutting fluid to prevent them from flowing into the liquid storage chamber 7; Reference Figure 4 , a scraper 14 is fixedly connected between the supports 11 at the output end of the conveyor belt 10. The upper side of the scraper 14 is in direct contact with the bottom belt surface of the conveyor belt 10, and is used for cleaning the waste chips adhered to the conveyor belt 10 to prevent them from entering the liquid storage chamber 7 along with the conveyor belt 10. A waste chip box 15 is arranged below the scraper 14 for storing the waste chips removed by the conveyor belt 10; In this embodiment, during the machining of parts, the cutting fluid in the liquid storage chamber 7 is conveyed by the hydraulic pump 9 through a pipeline to the cutting fluid nozzle 8 on the machining part 4 and sprayed out to clean the parts being machined and cool the cutting tools. During the process, the sprayed cutting fluid will carry part of the waste chips and fall on the conveyor belt 10. Then, the cutting fluid will flow towards the input end of the conveyor belt 10 under the action of gravity. After the waste chips are filtered out by the filter plate 13, it flows into the liquid storage chamber 7; After the machining of the parts is completed, the waste chips and cutting fluid in the machining chamber 2 are blown onto the upper side of the conveyor belt 10 by an air gun manually. Similarly, the cutting fluid on the conveyor belt 10 will flow into the liquid storage chamber 7 from the input end of the conveyor belt 10 under the action of gravity. After the cutting fluid has flowed out, the driving motor 12 is started to make the conveyor belt 10 rotate. The conveyor belt 10 carries the waste chips out of the numerical control machine tool 1 and falls into the waste chip box 15. Subsequently, the scraper 14 scrapes off the waste chips remaining on the conveyor belt 10 to prevent them from entering the liquid storage chamber 7.
[0018] Embodiment 2, the following structure is added on the basis of Embodiment 1: A liquid level sensor 16 is fixedly connected to the inner wall of the liquid storage chamber 7 near one side of the input end of the conveyor belt 10. The liquid level sensor 16 transmits the two groups of liquid level value data detected in the liquid storage chamber 7 before and after machining to the control box 26, which is calculated, judged and processed by the control box 26; Reference Figure 7, on one inner wall of the liquid storage chamber 7, a pH sensor 17 is fixedly connected. The pH sensor 17 is used to detect the pH value of the cutting fluid. In the liquid storage chamber 7, an oil slick thickness measurement sensor 18 is provided. The oil slick thickness measurement sensor 18 floats on the surface layer of the cutting fluid stored in the liquid storage chamber 7 and reacts the thickness of the oil slick to the signal transmitter through the built-in float, so as to detect the thickness of the oil slick generated by the cutting fluid in the liquid storage chamber 7. On the inner wall of the liquid storage chamber 7 and on one side of the pH sensor 17, a liquid outlet hole 19 is provided; Reference Figure 1 and reference Figure 2 , the liquid outlet hole 19 is connected to an oil skimmer 20 through a pipeline, which is used to clean the oil slick in the liquid storage chamber 7. The oil skimmer 20 is fixedly connected to the outer wall of the numerical control machine tool 1. On one side of the liquid storage chamber 7 away from the pH sensor 17, a liquid change hole 21 and a liquid inlet hole 22 are respectively provided. The liquid change hole 21 is connected to the output end of the oil skimmer 20 through a pipeline. The oil skimmer 20 sucks the cutting fluid in the liquid storage chamber 7 through the liquid outlet hole 19 to clean the oil slick, and the cleaned cutting fluid then flows back into the liquid storage chamber 7 through the output end. Below the oil skimmer 20, a waste oil storage tank 23 is provided, which is used to store the waste oil filtered out by the oil skimmer 20. The liquid inlet hole 22 is connected to a suction pump 24 through a pipeline. The suction pump 24 is fixedly connected to the outer wall of the numerical control machine tool 1. The input end of the suction pump 24 is connected to a stock solution tank 25 through a pipeline. The stock solution tank 25 is located on one side of the numerical control machine tool 1 and is used to supplement the cutting fluid into the liquid storage chamber 7. On the right outer wall of the numerical control machine tool 1, a control box 26 is fixedly connected. The liquid level sensor 16, the pH sensor 17, the oil slick thickness measurement sensor 18, the oil skimmer 20, the suction pump 24, and the drive motor 12 are all signal-connected to the control box 26.
[0019] In this embodiment, the normal liquid level value of the liquid storage chamber 7 is set to H through the control box 26. H is the liquid level value measured after one machining process flows into the liquid storage chamber 7, and it satisfies the state of being able to directly carry out the next machining process in a cycle without the need for additional liquid replenishment, that is: ; where Q1 is the total amount of cutting fluid consumed in advance for one machining process, Q2 is the amount of cutting fluid that is attached to waste chips and other components and cannot flow back into the liquid storage chamber 7 after one machining process as allowed in advance, and S is the bottom area of the liquid storage chamber 7; After setting that the machining is completed, the maximum time value for the cutting fluid to flow back into the liquid storage chamber 7 is T; after exceeding the time T, waste chip treatment is carried out; When machining is in progress, the conveyor belt 10 is not started; Within the time T after the machining is completed, the actual liquid level value of the cutting fluid in the liquid storage chamber 7 is denoted as S, and S is compared with H; When S≥H, it indicates that the cutting fluid capacity in the liquid storage chamber 7 is sufficient to support the amount of cutting fluid required for the next machining process, so no liquid replenishment is required when carrying out the next machining; When S < H, it indicates that the amount of cutting fluid in the liquid storage chamber 7 is insufficient to support the amount of cutting fluid required for the next machining operation. Therefore, replenishment is needed during the next machining operation. Subsequently, the control box 26 controls the oil pump 24 to pump new cutting fluid from the stock solution tank 25 into the liquid storage chamber 7 to mix with the original cutting fluid and restore the liquid level value to the set liquid level value H.
[0020] Generally, the normal pH value of the cutting fluid should be between 8.3 and 9.2. When the control box 26 detects through the pH sensor 17 that the pH values of multiple groups of cutting fluid in the liquid storage chamber 7 continue to decrease, indicating a downward trend in the pH value of the cutting fluid in the liquid storage chamber 7, the control box 26 controls the oil pump 24 to pump new cutting fluid from the stock solution tank 25 into the liquid storage chamber 7 to mix with the original cutting fluid, so that the pH value of the cutting fluid in the liquid storage chamber 7 is maintained between 9 and 9.2. This can better keep the cutting fluid in the liquid storage chamber 7 with better rust prevention performance, while inhibiting the growth of microorganisms and playing a better cleaning role in the machining of parts.
[0021] The control box 26 sets the normal measurement thickness of the floating oil thickness sensor 18 to be between 0 and 0.5 cm. When the floating oil thickness sensor 18 detects that the floating oil thickness in the liquid storage chamber 7 reaches 0.5 cm or more, the control box 26 controls the skimmer 20 to work, pumping the cutting fluid in the liquid storage chamber 7 into the skimmer 20 for floating oil filtration and then conveying it back into the liquid storage chamber 7 through the skimmer 20 to complete the cleaning of the floating oil in the cutting fluid in the liquid storage chamber 7.
[0022] A method for using a cleaning device for machining: S1: After machining is completed, the remaining waste chips and cutting fluid in the machining chamber 2 are blown onto the upper side of the conveyor belt 10 by an air gun manually. S2: The control box 26 sets the normal liquid level value of the liquid storage chamber 7 to be H. H is the liquid level value measured after one machining operation flowing into the liquid storage chamber 7 and meets the state of being able to directly carry out the next machining operation in a cyclic manner without the need for replenishment. After machining is completed, the maximum time value for the cutting fluid to flow back into the liquid storage chamber 7 is T. During the time T after machining is completed, the actual liquid level value of the cutting fluid in the liquid storage chamber 7 is denoted as S. S3: During machining, the conveyor belt 10 is not started. During the time T after machining is completed, when the actual liquid level value S of the cutting fluid in the liquid storage chamber 7 ≥ the normal liquid level value H, no replenishment is required for the next machining operation. When the actual liquid level value S of the cutting fluid in the liquid storage chamber 7 < the normal liquid level value H, replenishment is required for the next machining operation. Subsequently, the control box 26 controls the oil pump 24 to pump new cutting fluid from the stock solution tank 25 into the liquid storage chamber 7 to mix with the original cutting fluid and restore the liquid level value to the set liquid level value H. S4: After time T after machining is completed, the control box 26 starts the drive motor 12 to convey the waste chips on the conveyor belt 10 out of the numerical control machine tool 1 and into the waste chip box 15. At the same time, the scraper 14 further scrapes and cleans the conveyor belt 10. S5: When the control box 26 detects through the pH sensor 17 that the pH values of multiple groups of cutting fluids in the liquid storage chamber 7 continue to decrease, indicating that the pH value of the cutting fluid in the liquid storage chamber 7 has a downward trend, the control box 26 controls the oil pump 24 to pump new cutting fluid from the stock solution tank 25 into the liquid storage chamber 7 to mix with the original cutting fluid, so that the pH value of the cutting fluid in the liquid storage chamber 7 is maintained between 9 and 9.2. S6: When the floating oil thickness measurement sensor 18 detects that the floating oil thickness in the liquid storage chamber 7 reaches 0.5 cm or more, the control box 26 controls the oil skimmer 20 to work, pumps the cutting fluid in the liquid storage chamber 7 into the oil skimmer 20 for floating oil filtration, and then conveys it back into the liquid storage chamber 7 through the oil skimmer 20 to complete the cleaning of the floating oil in the cutting fluid in the liquid storage chamber 7.
