Description

Technical Field

[0001] This invention belongs to the technical field of machine tool cleaning equipment, specifically referring to a slag removal device for CNC machine tools. Background Technology

[0002] During the machining process of CNC machine tools, cutting fluid plays a role in cooling, lubrication and heat removal. However, as machining progresses, impurities such as metal chips and powder will be mixed into the cutting fluid, affecting the circulation of the cutting fluid and the stability of the machine tool. Filter screens are usually installed to intercept solid waste residue.

[0003] Over time, filter screens can become clogged due to the accumulation of waste materials, leading to a decrease in filtration efficiency. This not only affects the circulation of cutting fluid and reduces machining accuracy, but also accelerates the wear and tear on machine tools, thereby affecting the working efficiency of machine tools and the service life of cutting fluid. Especially in high-intensity machining environments, filter screens often become difficult to clean due to the long-term accumulation of metal shavings and other hard particles, further weakening the filtration effect.

[0004] Existing filter cleaning methods mostly rely on manual cleaning or backflushing equipment. However, these methods are not effective for handling heavy and bulky metal residues. Although backflushing equipment can clean the filter, it has limited effectiveness in cleaning heavy or sticky metal shavings and waste. It often cannot completely remove the waste, resulting in frequent clogging of the filter and failing to meet the needs of high-precision and high-efficiency processing. Summary of the Invention

The second rotating wheel is connected to the output end of the servo motor. The first rotating wheel is rotatably connected to the slag-cleaning filter screen. The side of the second rotating wheel is provided with a recessed notch.

[0008] Furthermore, the slag removal filter screen is provided with filter mesh and bottom scraper. The bottom scraper is located at the bottom edge of the slag removal filter screen and is configured to clean the residue deposited in the drainage trough.

[0009] Furthermore, the rotating slag removal assembly also includes a slag removal roller and a slag removal motor. The slag removal roller is rotatably disposed in the drainage trough, and the slag removal motor is configured to drive the rotation of the slag removal roller. A spiral slag removal blade is provided on the outer surface of the slag removal roller, and the top of the spiral slag removal blade contacts the inner wall of the drainage trough.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] like Figures 1-8 As shown, this embodiment is mainly used on machine tools to clean cutting fluid mixed with solid residues during machining. It includes a rotary cleaning component 100 and a vibration filtering component 200. The rotary cleaning component 100 discharges the cutting fluid mixed with solid residues from the machine tool, and the vibration filtering component 200 filters the cutting fluid mixed with solid residues to remove the solid residues.

[0022] The rotary cleaning assembly 100 proposed in this embodiment includes a drainage trough 102, which is inclined. The cutting fluid mixed with solid residue flows downward in the drainage trough 102, and the vibration filter assembly 200 is disposed at the bottom of the drainage trough 102.

[0023] The vibration filter assembly 200 proposed in this embodiment includes a slag-removing filter screen 201, a sliding bracket 202, and a pulse vibration mechanism 203. The sliding bracket 202 is disposed on the drainage trough 102, and the slag-removing filter screen 201 is slidably connected to the sliding bracket 202. A compression spring 206 is provided on the sliding bracket 202 and is connected to the slag-removing filter screen 201. The pulse vibration mechanism 203 is disposed on one side of the slag-removing filter screen 201, and the pulse vibration mechanism 203 applies an intermittent pulsating thrust to the slag-removing filter screen 201. When the actuator 203 pushes the cleaning filter screen 201 to slide on the sliding bracket 202, the compression spring 206 is compressed and stores energy. When the thrust of the pulse vibration mechanism 203 disappears, the compression spring 206 quickly rebounds, causing the cleaning filter screen 201 to vibrate on the sliding bracket 202, thereby shaking off the solid residues that are stuck on the cleaning filter screen 201. Through this repeated vibration process, the solid residues on the cleaning filter screen 201 are removed, thereby achieving automatic cleaning and self-maintenance, keeping the filter screen unobstructed, and ensuring the continuous and stable filtration effect.

[0024] This embodiment effectively solves the problems of filter screen clogging and low cleaning efficiency in traditional cleaning devices by the synergistic effect of the rotary cleaning component 100 and the vibration filter component 200. The inclined drainage channel 102 allows the mixed cutting fluid to flow smoothly, avoiding liquid stagnation and improving the efficiency of liquid discharge. The vibration filter component 200, through the cooperation of the pulse vibration mechanism 203 and the compression spring 206, can provide strong cleaning ability during the filtration process, ensuring that the filter screen can remove fine solid residues, reducing clogging caused by solid residue accumulation, and reducing the maintenance frequency and cost of the equipment.

[0025] Meanwhile, the automation level of the slag removal device ensures the continuous cleanliness of the cutting fluid during the machining process, extends the service life of the cutting fluid, and improves machining quality and efficiency. The design of this embodiment is simple and compact, making it easy to integrate into existing machine tool systems without large-scale modifications. It has high application value and wide applicability.

[0026] The pulse vibration mechanism 203 proposed in this embodiment improves the cleaning effect of the cleaning screen 201 by precisely controlling the vibration frequency and vibration amplitude, ensuring efficient removal of solid residues. The structure of the pulse vibration mechanism 203 includes a first rotating wheel 207, a second rotating wheel 208, and a servo motor 210. The servo motor 210 is installed on the drainage trough 102, and its output end is connected to the second rotating wheel 208. When the servo motor 210 works, it drives the second rotating wheel 208 to rotate, and the second rotating wheel 208 contacts the first rotating wheel 207, thereby transmitting the thrust to the cleaning screen 201. At this time, the cleaning screen 201 is subjected to the thrust, and the compression spring 206 enters the compressed state.

[0027] When the second rotating wheel 208 rotates to the position of the recessed notch 209, a gap is formed between the second rotating wheel 208 and the first rotating wheel 207. At this time, the compression spring 206 quickly rebounds, causing the cleaning filter screen 201 to move rapidly over a short distance. This vibration of the cleaning filter screen 201 causes the solid residues attached to the filter screen to be thrown off, achieving automatic cleaning. This vibration method effectively removes the blockages on the filter screen, avoids clogging of the filter screen, and maintains the smooth flow of cutting fluid and the filtration effect.

[0028] In this embodiment, the speed control function of the servo motor 210 can flexibly control the vibration frequency of the cleaning filter screen 201, thereby effectively removing solid residues of different sizes and adhesion. At the same time, adjusting the depth of the recessed notch 209 can precisely control the vibration amplitude of the cleaning filter screen 201, further optimizing the cleaning effect and ensuring the cleaning requirements under different working conditions. Compared with traditional backflushing and manual cleaning methods, the pulse vibration mechanism has a higher level of automation and cleaning efficiency, reduces manual intervention, lowers maintenance costs, improves the overall performance and reliability of the cleaning device, and increases the processing efficiency of machine tools and the service life of cutting fluid.

[0029] In this embodiment, the lower half of the slag removal filter 201 is provided with filter mesh 204 for effectively filtering mixed solid residues in the cutting fluid. By rationally arranging the position of the filter mesh, the efficient filtration of large particles of residue is ensured, avoiding complex design of the filter structure, thereby reducing the processing difficulty and cost.

[0030] In addition, a scraper 205 is provided at the bottom edge of the slag removal filter screen 201. When the filter screen vibrates back and forth, the bottom scraper 205 will push away the residue deposited at the bottom of the drainage trough 102, preventing it from hindering the vibration of the filter screen. This effectively reduces the impact of the deposits on the filter screen, ensures the stability of the filtration effect, improves the performance of the automated cleaning system, reduces manual intervention and equipment maintenance, and improves the working efficiency of the machine tool and the service life of the cutting fluid.

[0031] The rotary cleaning assembly 100 of this embodiment improves the fluidity of cutting fluid and solid residue through the cooperation of the cleaning roller 101 and the cleaning motor 103. The cleaning roller 101 is rotatably disposed in the drainage trough 102 and is driven by the cleaning motor 103. When the cleaning roller 101 rotates, the spiral cleaning blades 104 on the cleaning roller 101 push the cutting fluid and solid residue to flow, thereby accelerating the separation of impurities.

[0032] The top of the spiral cleaning blade 104 contacts the inner wall of the drainage groove 102, effectively scraping away solid residues deposited at the bottom of the drainage groove and preventing residue accumulation. The spiral cleaning blade 104 is made of rubber, which provides sufficient scraping force to remove deposits while preventing damage to the inner wall of the drainage groove, thus extending the service life of the equipment. Through the operation of this rotating cleaning component, the flow of cutting fluid is further promoted, the filtration effect is more stable, the accumulation and clogging of solid residues are reduced, the machining efficiency of the machine tool is significantly improved, and the maintenance cost is reduced.

[0033] This embodiment also includes a cutting fluid circulation component 300. Through the coordinated operation of the drain pipe 301 and the liquid container 302, the effective recovery and recycling of cutting fluid in the slag removal device is ensured. The bottom end of the drain tank 102 is provided with a drain hole 105. After being treated by the vibration filter component 200, the cutting fluid enters the drain pipe 301 through the drain hole 105 and flows into the liquid container 302 for temporary storage, reducing the waste of cutting fluid.

[0034] This not only ensures that the filtered cutting fluid can be returned to the liquid container 302, effectively extending the service life of the cutting fluid, but also reduces the consumption of cutting fluid and environmental pollution; the recycling process makes the system more efficient, reduces dependence on external cutting fluid, further improves the machining efficiency and economy of the machine tool, and reduces operating costs.

[0035] In this embodiment, the liquid container 302 is equipped with a circulating water pump 303, which is used to extract the cutting fluid in the liquid container 302 and recycle it. The circulating water pump 303 extracts the cutting fluid from the liquid container 302, processes it, and then returns it to the machine tool system, so that the cutting fluid can be continuously circulated in the system, avoiding unnecessary waste and improving the resource utilization efficiency of the system.

[0036] By setting up the circulating water pump 303, the recovery and reuse of cutting fluid is more efficient. After filtration, the treated cutting fluid can be sent back to the machine tool working area, ensuring an adequate supply of cutting fluid and reducing the need to replace the cutting fluid.

[0037] This embodiment also includes a machine tool guide plate 400, which serves as a guide and distribution device for the flow of cutting fluid. The machine tool guide plate 400 is disposed on the machine tool and connected to the drainage tank 102. The machine tool guide plate 400 is provided with a guide channel 401, and its drain outlet is connected to the drainage tank 102. The function of the machine tool guide plate is to guide the cutting fluid and residue mixed during the operation of the machine tool to the drainage tank 102 for subsequent cleaning and recycling.

[0038] In practical use, the machine tool guide plate 400 can effectively guide the cutting fluid and solid residue to the drainage tank 102. During the flow of the cutting fluid, the residue first collects on the machine tool guide plate 400, and then is guided through the guide channel 401 and flows into the drainage tank 102. This ensures that the residue and cutting fluid can enter the slag removal system for treatment efficiently, optimizes the slag removal process, improves the system's recovery efficiency, ensures the efficient operation of the slag removal device, and also avoids the accumulation of residue on the machine tool surface, reducing the difficulty of equipment maintenance.

[0039] The bottom of the drainage trough 102 proposed in this embodiment is provided with an adjusting bracket 106, the length of which is adjustable. The height and angle of the drainage trough 102 can be adjusted according to actual needs, thereby optimizing the flow path and drainage effect of the cutting fluid. By adjusting the length of the bracket 106, the inclination of the drainage trough 102 can be precisely controlled to ensure that the cutting fluid can flow smoothly and be effectively guided into the slag removal component 200 when it flows into the drainage trough 102.

[0040] The adjustable bracket 106 has significant flexibility and adaptability in practical applications. It can adjust the position of the drain trough 102 according to the working state of different machine tools or the characteristics of the cutting fluid, ensuring that the drain trough can maximize its guiding function under different working conditions. This not only improves the discharge efficiency of the cutting fluid, but also helps to optimize the slag removal process in the system and improve the overall operational stability and reliability of the slag removal device.

[0041] When using the slag removal device for CNC machine tools of the present invention, first install each component onto the machine tool, ensuring that the drainage tank, rotary slag removal assembly, vibration filter assembly, cutting fluid circulation assembly, and machine tool guide plate are correctly connected. Adjust the adjusting bracket at the bottom of the drainage tank to ensure that its tilt angle is appropriate so that the cutting fluid and residue can flow smoothly into the slag removal system.

[0042] After the machine tool is started, the cutting fluid mixes with solid residue and is guided into the drainage tank through the guide groove of the machine tool's guide plate. At this time, the cleaning roller rotates under the drive of the cleaning motor, and the spiral cleaning blades push the cutting fluid and residue to flow, scraping away the solid residue deposited at the bottom of the drainage tank. Next, the pulse vibration mechanism in the vibration filter assembly applies intermittent thrust to the cleaning filter screen, causing the screen to vibrate on the sliding support. The compression spring provides a rebound force, helping to remove solid residue from the filter screen.

[0043] The filtered cutting fluid flows into the drain pipe through the drain hole and is then transported to a liquid container for temporary storage. The cutting fluid in the liquid container is then pumped out by a circulating water pump and returned to the machine tool for reuse. Finally, the working status of the slag removal device is checked regularly, and components such as the slag removal rollers and filter screen are cleaned to ensure long-term efficient operation. Through this working principle, the device achieves efficient cleaning of solid residues, filtration and recovery of cutting fluid, extending the service life of the cutting fluid, reducing maintenance costs, and improving the machining efficiency of the machine tool.
