Description

Technical Field

[0001] This utility model belongs to the field of nano-polishing liquid fine polishing technology, specifically, it relates to a fine polishing device for processing metal materials using nano-polishing liquid. Background Technology

[0002] With the development of high-end manufacturing, the surface quality requirements for metal parts (such as aerospace components, precision medical devices, optical molds, etc.) are increasing, and the surface roughness (Ra) often needs to reach the nanometer level. To achieve this goal, fine polishing technology using nano polishing slurry has become a key process. Nano polishing slurry uses nano-sized abrasives (such as nano diamond, cerium oxide, silicon oxide, etc.) to perform micro-cutting and chemical action on the metal surface, thereby obtaining a defect-free, mirror-like surface.

[0003] In the prior art, fine polishing equipment using nano polishing slurry typically includes a polishing head, a workpiece clamping device, a polishing slurry supply system, and a control system; the polishing slurry supply system generally includes a storage tank, a delivery pump, pipelines, and nozzles, used to continuously and uniformly deliver the nano polishing slurry to the polishing interface.

[0004] However, nano-polishing slurries present a significant technical challenge: due to their extremely high specific surface area and surface energy, nanoparticles are prone to agglomeration and precipitation in liquid media, forming micron-sized aggregates much larger than originally designed. This inherent characteristic has a serious negative impact on the fine polishing process, resulting in the following inherent defects in existing fine polishing equipment: unstable polishing quality and easy surface damage; reduced equipment reliability and high maintenance costs; low utilization rate of polishing slurry and crude process control.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To address the problem of nano-polishing slurry agglomeration, the basic concept of the technical solution adopted in this utility model is as follows: A precision polishing device for processing metal materials using nano-polishing slurry includes a processing component for monitoring and treating the agglomeration of the nano-polishing slurry. The processing component includes a processing tank, a particle monitoring module, an ultrasonic module, and a stirring rod. The particle monitoring module is located at the bottom of the processing tank, and its monitoring end extends into the interior of the processing tank. The ultrasonic module is fixedly connected to one end of the processing tank. The stirring rod is arranged around the processing tank and is connected to the output end of the ultrasonic module.

[0007] In a preferred embodiment of this utility model, a drive motor is provided at the other end of the processing tank, and the output end of the drive motor is fixedly connected to a mounting plate through a coupling. The mounting plate is located inside the processing tank.

[0008] In a preferred embodiment of this utility model, the stirring rods are arranged around the mounting plate, and each stirring rod is fixedly connected to a corresponding position on the mounting plate.

[0009] In a preferred embodiment of this utility model, one end of the mounting plate is fixedly connected to a bearing seat, which is fixedly connected to one end of the processing tank. The bearing seat is a common bearing seat.

[0010] In a preferred embodiment of this utility model, the processing tank is provided with interlaced connecting pipes, each of which is fixedly connected to the processing tank and is used for feeding and discharging materials respectively.

[0011] In a preferred embodiment of this utility model, each connecting pipe is provided with an array of Venturi pipes, and each Venturi pipe is fixedly connected to the inner wall of the connecting pipe.

[0012] In a preferred embodiment of this utility model, a turbulence module is fixedly connected to the corresponding position of each connecting pipe, and a flow amplification end is provided at the connection between the connecting pipe and the turbulence module. Each flow amplification end is fixedly connected to the corresponding connecting pipe and the turbulence module.

[0013] In a preferred embodiment of this utility model, each turbulence module is provided with a collection end, each collection end is fixedly connected to the corresponding turbulence module, and each collection end is provided with a through hole.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This is a precision polishing device for processing metal materials using nano-polishing slurry. The system monitors the state of the polishing slurry in real time through a particle monitoring module. Once the risk of particle agglomeration is detected (particle density is too low), the ultrasonic module can be automatically activated for precise processing. This closed-loop control mechanism of "monitoring-feedback-processing" transforms passive processing into active prevention, effectively ensuring the dispersion stability and performance consistency of the polishing slurry during transportation and use.

[0015] 2. This precision polishing equipment for processing metal materials using nano-polishing slurry employs a multi-mechanism synergistic effect to comprehensively prevent deposition and agglomeration: the system comprehensively utilizes three physical methods: mechanical stirring (generating appropriate shear force), ultrasonic oscillation (dispersing agglomerated particles), and fluid dynamics design (Venturi tube pressurization and turbulence generation). These three mechanisms play a role at the macroscopic, microscopic, and flow processes, respectively, forming multiple layers of protection and synergistically avoiding deposition and agglomeration problems that may occur in the polishing slurry due to static conditions, changes in flow rate, or molecular forces.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] Please see Figure 1-5 A precision polishing device for processing metal materials using nano-polishing slurry includes a processing component for monitoring and treating the agglomeration of the nano-polishing slurry. The processing component includes a processing tank 1, a particle monitoring module 2, an ultrasonic module 3, and a stirring rod 34. The particle monitoring module 2 is located at the bottom of the processing tank 1, and the monitoring end of the particle monitoring module 2 extends into the interior of the processing tank 1. The ultrasonic module 3 is fixedly connected to one end of the processing tank 1. The stirring rod 34 is arranged around the processing tank 1, and the stirring rod 34 is connected to the output end of the ultrasonic module 3. In the process, the nano-polishing slurry is first sent to the processing tank 1. The particle size of the nano-polishing slurry is monitored in real time by the particle monitoring module 2. When the particle size of the nano-polishing slurry is too low and agglomeration occurs, the ultrasonic module 3 is activated. The ultrasonic module 3 transmits ultrasonic waves to the stirring rod 34. The stirring rod 34 performs ultrasonic treatment on the nano-polishing slurry inside the processing tank 1, which shakes apart the agglomerated particles in the nano-polishing slurry, thus realizing the ability to handle agglomeration during the transportation of nano-polishing slurry.

[0021] It is worth noting that the particle monitoring module 2 includes: a sampling tube, a PTFE filter belt, a filter belt conveying mechanism, a dual-path detection unit, a flow meter, a flow regulating valve, and a vacuum pump; the dual-path detection unit includes: a first detection unit and a second detection unit, the first detection unit including a first β-ray source and a first β-ray detector; the second detection unit including a second β-ray source and a second β-ray detector; the dual-path detection unit is located between two filter belt conveying mechanisms; the filter belt conveying mechanism is a pulley; the above-mentioned utility model introduces a second detection unit, which eliminates the decay effect of radon in particulate matter through long-term counting detection, and introduces a correction coefficient K for self-correction, thereby improving measurement accuracy; the particle monitoring module 2 has been disclosed in the existing β-ray particulate matter concentration monitor CN222013896U, and will not be described in detail here.

[0022] The other end of the processing tank 1 is equipped with a drive motor 32. The output end of the drive motor 32 is fixedly connected to a mounting plate 33 via a coupling. The mounting plate 33 is located inside the processing tank 1. The stirring rods 34 are arranged around the mounting plate 33, and each stirring rod 34 is fixedly connected to a corresponding position on the mounting plate 33. One end of the mounting plate 33 is fixedly connected to a shaft seat end 31, which is fixedly connected to one end of the processing tank 1. The shaft seat end 31 is a common bearing seat. In the process, the nano-polishing slurry is first sent to the processing tank 1. The particle size of the nano-polishing slurry is monitored in real time by the particle monitoring module 2. When the particle size of the nano-polishing slurry is too low and agglomeration occurs, the ultrasonic module 3 is activated. The ultrasonic module 3 transmits ultrasonic waves to the stirring rod 34. The stirring rod 34 performs ultrasonic treatment on the nano-polishing slurry inside the processing tank 1, which shakes apart the agglomerated particles in the nano-polishing slurry, thus realizing the ability to handle agglomeration during the transportation of nano-polishing slurry. The drive motor 32 is always in operation during the operation of this device. The output end of the drive motor 32 drives the mounting plate 33 to rotate through the coupling. The rotation of the mounting plate 33 drives the stirring rod 34 to rotate. During the rotation of the stirring rod 34, the nano polishing liquid is stirred and shear force is generated to avoid the phenomenon of sedimentation and agglomeration during the normal transportation of the nano polishing liquid. In addition, the axial rotation of the drive motor 32 is slow to avoid excessive shear force causing the nano polishing liquid to agglomerate.

[0023] The processing tank 1 is provided with staggered connecting pipes 11. Each connecting pipe 11 is fixedly connected to the processing tank 1. The connecting pipes 11 are used for feeding and discharging respectively. Each connecting pipe 11 is provided with an array of venturi pipes 13. Each venturi pipe 13 is fixedly connected to the inner wall of the connecting pipe 11. Each corresponding position of each connecting pipe 11 is fixedly connected to a turbulence module 12. A flow-expanding end 14 is provided at the connection between the connecting pipe 11 and the turbulence module 12. Each flow-expanding end 14 is fixedly connected to the corresponding connecting pipe 11 and turbulence module 12. Each turbulence module 12 is provided with a collecting end 15. Each collecting end 15 is fixedly connected to the corresponding turbulence module 12, and each collecting end 15 is provided with a through hole. The nano-polishing slurry is transported through the connecting pipe 11. When the nano-polishing slurry passes through the Venturi pipe 13 area, the slurry is pressurized and transported by the setting and structure of the Venturi pipe 13. The nano-polishing slurry passes through the expansion end 14 area, where the expansion end 14 diffuses and releases the pressure of the nano-polishing slurry to the gap between the turbulence module 12 and the collection end 15 and the middle of the collection end 15. Turbulence is generated in the gap between the turbulence module 12 and the collection end 15 and the middle of the collection end 15. Through the combined action of turbulence acceleration and acceleration by the Venturi pipe 13, the nano-polishing slurry is prevented from depositing and agglomerating during transportation.

[0024] Working Principle: The nano-polishing slurry is first fed into processing tank 1. The particle size distribution of the slurry is monitored in real time by particle monitoring module 2. When the particle size is too low and agglomeration occurs, ultrasonic module 3 is activated. Ultrasonic module 3 transmits ultrasonic waves to stirring rod 34, which ultrasonically treats the nano-polishing slurry inside processing tank 1, dispersing the agglomerated particles and achieving the ability to handle agglomeration during transport. Drive motor 32 is always operational during the device's operation. The output of drive motor 32 drives mounting plate 33 to rotate via a coupling. The rotation of mounting plate 33 drives stirring rod 34, which in turn stirs the nano-polishing slurry and generates shear force, preventing agglomeration during nano-polishing slurry processing. During normal transport of the liquid, sedimentation and agglomeration occur. The axial rotation of the drive motor 32 is slow to avoid excessive shear force that could cause the nano-polishing liquid to agglomerate. The nano-polishing liquid is transported through the connecting pipe 11. When the nano-polishing liquid passes through the Venturi pipe 13 area, the Venturi pipe 13 and its own structure pressurize and transport the nano-polishing liquid. The nano-polishing liquid passes through the expansion end 14 area, where the expansion end 14 diffuses and releases the pressure of the nano-polishing liquid to the gap between the turbulence module 12 and the collection end 15 and the middle of the collection end 15. Turbulence is generated in the gap between the turbulence module 12 and the collection end 15 and the middle of the collection end 15. Through the combined action of turbulence acceleration and acceleration by the Venturi pipe 13, sedimentation and agglomeration of the nano-polishing liquid during transport are avoided.
