Description

Technical Field

[0001] This utility model relates to the technical field of valve parts processing equipment, and in particular to a cutting fluid polishing device. Background Technology

[0002] Valve components are key parts of fluid control systems. They typically have intricate flow channel structures inside to achieve precise regulation and cut-off of the medium.

[0003] During machining, especially in processes such as cutting and drilling of small flow channels or complex cavities, factors such as tool wear, unreasonable cutting parameters, or insufficient cooling and lubrication can easily lead to the incomplete removal of metal chips in a timely manner. This not only affects the quality of subsequent machining but also poses potential risks to the assembly and performance of the valve body. Furthermore, the surfaces of valve parts are relatively rough after machining. During subsequent use, metal powder from these rough parts is easily shed and enters the valve's working medium, which can severely impact the valve's performance and reliability, and may even lead to major accidents.

[0004] There is currently no publicly available technical solution that can both remove iron filings generated during the internal machining of valve parts and polish the internal machined surfaces of valve parts. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cutting fluid polishing device to solve the technical problem in the prior art that it is impossible to both remove iron filings generated during processing and polish the internal machined surfaces.

[0006] This utility model provides a cutting fluid polishing device, comprising:

[0007] A liquid storage device with a hollow interior, containing cutting fluid containing polishing particles;

[0008] An input pipe is provided between the liquid reservoir and the workpiece to be processed. One end of the pipe extends toward the workpiece until it is aligned with the workpiece, and the other end extends into the liquid reservoir until its end penetrates into the cutting fluid.

[0009] A drive unit, disposed on the input pipe, is used to draw the cutting fluid in the reservoir into the input pipe and inject the cutting fluid in the input pipe into the workpiece to be processed, thereby removing iron filings from the workpiece and polishing the workpiece.

[0010] Optionally, it also includes:

[0011] A recovery pipe is provided between the liquid storage device and the workpiece to be processed. One end of the pipe is connected to the liquid storage device and communicates with the inside of the liquid storage device. The other end extends toward the workpiece to be processed. The driving component drives the cutting fluid used at the workpiece to flow into the recovery pipe.

[0012] Optionally, a recovery filter is provided on the recovery pipeline, which is used to filter the cutting fluid in the recovery pipeline and recover impurities in the cutting fluid.

[0013] Optionally, a stirring element is provided at the liquid storage device, which is used to stir and mix the cutting fluid in the liquid storage device.

[0014] Optionally, it also includes a laser particle counter, which is installed on the input pipe or the recovery pipe and is used to detect the size and content of particles in the cutting fluid in the input pipe or the recovery pipe. The laser particle counter is electrically connected to the agitator via a controller.

[0015] Optionally, it also includes:

[0016] A condenser is provided on the input pipe or the recovery pipe for cooling the cutting fluid in the input pipe or the recovery pipe;

[0018] Optionally, it also includes:

[0019] A pressure sensor is installed on the input pipe or the recovery pipe to detect the pressure of the cutting fluid in the input pipe or the recovery pipe. The pressure sensor is electrically connected to the controller and the drive unit.

[0022] Optionally, it also includes a liquid level sensor, which is disposed on the liquid storage container and is used to detect the content of cutting fluid in the liquid storage container.

[0023] Optionally, the cutting fluid is a diamond suspension.

[0024] The technical solution of this utility model has the following advantages:

[0025] The cutting fluid polishing device provided by this utility model uses a drive component to draw cutting fluid from the reservoir into the input pipe, and then injects the cutting fluid from the input pipe into the interior of the workpiece to be processed. The impact force of the cutting fluid thoroughly removes residual iron filings from the workpiece. At the same time, the cutting fluid contains polishing particles. When the cutting fluid washes over the interior of the workpiece, the polishing particles continuously rub against the interior surface of the workpiece, thereby reducing the roughness of the interior surface of the workpiece and polishing the interior of the workpiece. This inhibits the shedding of metal powder from the interior surface of the workpiece, prevents media contamination and accidents, and achieves simultaneous chip removal and polishing.

[0037] Example

[0038] Reference Figure 1-3 As shown, this utility model provides a cutting fluid polishing device, including a liquid storage component 1, an input pipe 3, and a driving component 4. The liquid storage component 1 is configured as a liquid storage tank, and the liquid storage component 1 is hollow inside, containing cutting fluid 2. The cutting fluid 2 contains polishing particles, which can polish the workpiece 16 to be processed. The input pipe 3 is configured as a tube with openings at both ends. One end is connected to the top of the liquid storage component 1 and extends into the liquid storage component 1 until its end penetrates into the cutting fluid 2, so that the opening at this end is immersed in the cutting fluid 2, which facilitates the input pipe 3 to draw the cutting fluid 2 from the liquid storage component 1.

[0039] The drive unit 4 is configured as a drive pump, which is directly integrated into the input pipe 3. Specifically, the input pipe 3 is configured with two sections, and the drive pump is located between the two sections. The input end of the drive pump is connected to one section and the output end is connected to the other section. When the drive unit 4 is started, the cutting fluid 2 in the reservoir 1 can be drawn into the input pipe 3 and the cutting fluid 2 in the input pipe 3 can be injected into the workpiece 16 under high pressure to remove the iron filings in the workpiece 16 and polish the workpiece 16.

[0040] In use, the drive unit 4 is first activated, and the drive unit 4 starts working, thereby drawing the cutting fluid 2 from the reservoir 1 and sucking the cutting fluid 2 from the reservoir 1 into the input pipe 3. It can also inject the cutting fluid 2 from the input pipe 3 into the interior of the workpiece 16 to be processed. The impact force of the cutting fluid 2 is used to thoroughly remove the residual iron filings inside the workpiece 16. At the same time, the cutting fluid 2 contains polishing particles. When the cutting fluid 2 washes the interior of the workpiece 16, the polishing particles will continuously rub against the interior surface of the workpiece 16, thereby reducing the roughness of the interior surface of the workpiece 16 and polishing the interior of the workpiece 16. This inhibits the shedding of metal powder from the interior surface of the workpiece 16, prevents media contamination and accidents, and achieves simultaneous chip removal and polishing.

[0041] Specifically, the cutting fluid 2 is set as a diamond suspension, and the diamond particles in the diamond suspension are the polishing particles in the cutting fluid 2. In this embodiment, it is not limited to using only diamond suspension as the cutting fluid 2. Other cutting fluids 2, such as a mixed suspension of diamond and boron carbide, can also be used, as long as they can flush and polish the inside of the workpiece 16 to be processed.

[0042] As one specific implementation method, refer to Figure 1 As shown, the cutting fluid polishing device also includes a recovery pipe 5. The recovery pipe 5 is configured as a pipe with openings at both ends. The recovery pipe 5 is located between the liquid storage unit 1 and the workpiece 16 to be processed. One end of the recovery pipe 5 extends towards the workpiece 16 and is located below the workpiece 16. The opening faces the workpiece 16. The used cutting fluid 2 at the workpiece 16 can flow into the recovery pipe 5 through the opening. The other end of the recovery pipe 5 is connected to the side wall of the liquid storage unit 1 and communicates with the interior of the liquid storage unit 1. The driving unit 4 can drive the used cutting fluid 2 at the workpiece 16 to flow into the recovery pipe 5 and return to the liquid storage unit 1 through the recovery pipe 5. The recovery pipe 5 can guide the used cutting fluid 2 back to the liquid storage unit 1, forming a closed-loop circulation system, which reduces the consumption cost of cutting fluid 2 and avoids the risk of secondary pollution caused by manual handling of used cutting fluid 2.

[0043] Since the cutting fluid 2 contains impurities, in order to prevent the impurities in the cutting fluid 2 collected by the recovery pipe 5 from entering the reservoir 1 and affecting subsequent use, a recovery filter 6 is installed on the recovery pipe 5. When the cutting fluid 2 in the recovery pipe 5 enters the recovery filter 6, the recovery filter 6 can filter the cutting fluid 2 and collect the impurities in the cutting fluid 2. The filtered cutting fluid 2 is then passed back into the recovery pipe 5 and into the reservoir 1, keeping the cutting fluid 2 clean and preventing the impurities in the recovered cutting fluid 2 from re-entering the workpiece 16 to be processed, causing scratches or secondary blockages.

[0044] As one specific implementation method, refer to Figure 1 As shown, it also includes a pressure sensor 11 and a flow sensor 12. The pressure sensor 11 is installed on the input pipe 3 or the recovery pipe 5 and is used to detect the pressure of the cutting fluid 2 in the input pipe 3 or the recovery pipe 5. The flow sensor 12 is installed on the input pipe 3 or the recovery pipe 5 and is used to detect the flow rate of the cutting fluid 2 in the input pipe 3 or the recovery pipe 5.

[0045] In this embodiment, both the pressure sensor 11 and the flow sensor 12 are mounted on the input pipe 3. The detection ends of both the pressure sensor 11 and the flow sensor 12 extend into the input pipe 3 and contact the cutting fluid 2. Both the flow sensor 12 and the pressure sensor 11 are electrically connected to the controller 14 and the drive unit 4. In use, the pressure sensor 11 and the flow sensor 12 can detect the flow rate and pressure parameters of the cutting fluid 2 in real time, and can be adjusted according to different workpieces 16 and specific requirements. When it is necessary to adjust the pressure parameter of the cutting fluid 2, the controller 14 controls the pump speed of the adjustment drive unit 4 to adjust the pressure of the cutting fluid 2. When it is necessary to adjust the flow rate of the cutting fluid 2, the controller 14 controls the pump output power of the adjustment drive unit 4 to adjust the flow rate of the cutting fluid 2.

[0046] As another implementation method, refer to Figure 1 As shown, a laser particle counter 8 is also provided. The laser particle counter 8 is installed on the input pipe 3 or the recovery pipe 5. In this embodiment, the laser particle counter 8 is installed on the input pipe 3. The detection end of the laser particle counter 8 extends into the input pipe 3 and contacts the cutting fluid 2 in the input pipe 3, thereby detecting the size and content of particles in the cutting fluid 2 in the input pipe 3, so as to avoid insufficient particle concentration or excessive particle wear in the cutting fluid 2.

[0047] To ensure uniform suspension of polishing particles in the cutting fluid 2 within the reservoir 1, a stirrer 7 is installed on the reservoir 1 at its bottom. The stirrer 7 agitates the cutting fluid 2 within the reservoir 1, maintaining uniform suspension of the polishing particles and ensuring consistent polishing intensity for each workpiece 16. This prevents poor or ineffective polishing due to particle sedimentation. Additionally, the laser particle counter 8 is electrically connected to the stirrer 7 via the controller 14. When the laser particle counter 8 detects insufficient concentration of polishing particles in the input pipe 3 or excessive particle wear, the controller 14 activates the stirrer 7 to agitate the cutting fluid 2 within the reservoir 1. If, after agitation, the laser particle counter 8 still detects insufficient concentration of polishing particles in the input pipe 3 or excessive particle wear, the controller 14 issues a fluid replacement alarm, thus ensuring the stability of the polishing quality.

[0048] Specifically, the stirring component 7 includes a stirring motor 71 and a stirring rod 72. The stirring rod 72 and the driving shaft of the stirring motor 71 are connected and coaxially arranged. The stirring rod 72 extends into the liquid storage container 1. When the stirring motor 71 is started, the stirring motor 71 can drive the stirring rod 72 to rotate, thereby stirring the cutting fluid 2 in the liquid storage container 1. Stirring blades can be provided on the side wall of the end of the stirring rod 72 that extends into the liquid storage container 1 to improve the stirring effect.

[0049] In addition, when the cutting fluid 2 is used to flush and polish the workpiece 16, the cutting fluid 2 will generate heat through friction, causing the temperature of the cutting fluid 2 to rise. In order to control the temperature of the cutting fluid 2, the cutting fluid polishing device also includes a condenser 9 and a temperature sensor 10. The temperature sensor 10 is installed on the input pipe 3 or the recovery pipe 5 and is used to detect the temperature of the cutting fluid 2 in the input pipe 3 or the recovery pipe 5. The temperature sensor 10 is electrically connected to the condenser 9 through the controller 14. The condenser 9 is installed on the input pipe 3 or the recovery pipe 5 and is used to cool the cutting fluid 2 in the input pipe 3 or the recovery pipe 5.

[0050] Specifically, the condenser 9 is installed on the recovery pipe 5 and downstream of the recovery filter 6. It can cool the cutting fluid 2 before it is recovered to the storage container 1. The temperature sensor 10 is installed on the input pipe 3 to directly detect the temperature of the cutting fluid 2 injected into the workpiece 16. When the temperature sensor 10 detects that the temperature of the cutting fluid 2 exceeds the preset maximum value, the controller 14 controls the condenser 9 to start. The condenser 9 cools the cutting fluid 2. At the same time, the agitator 7 can stir and mix the cooled cutting fluid 2 and the original cutting fluid 2 in the storage container 1. When the temperature sensor 10 detects that the temperature of the cutting fluid 2 is lower than the preset minimum value, the controller 14 controls the condenser 9 to stop working.

[0051] Since some cutting fluid 2 will remain on the workpiece 16, resulting in the loss of cutting fluid 2, a liquid level sensor 13 is installed on the liquid storage device 1. The liquid level sensor 13 is a liquid level sensor to detect the content of cutting fluid 2 in the liquid storage device 1 in real time, so that the staff can observe the content of cutting fluid 2 in time and add cutting fluid 2 in time.

[0052] As another implementation method, refer to Figure 1 As shown, it also includes a display screen 15, which is electrically connected to the laser particle counter 8, temperature sensor 10, drive unit 4, pressure sensor 11, flow sensor 12 and liquid level sensor 13. The display screen 15 can display the data detected by the laser particle counter 8, temperature sensor 10, pressure sensor 11, flow sensor 12 and liquid level sensor 13 in real time, as well as the rotation speed and output power of the drive unit 4, for the staff to observe and adjust.

[0053] Working Principle: During operation, first input the flow rate, pressure, and time. Based on these parameters, adjust the drive pump's speed, output power, and operating time. Then, the system starts. Simultaneously, the liquid level sensor detects the content of cutting fluid 2 in the storage container 1, activating the drive unit 4. After the pump starts, it draws the cutting fluid 2 from the storage container 1 into the input pipe 3. At this time, the temperature sensor 10, laser particle counter 8, pressure sensor 11, and flow sensor 12 simultaneously detect the cutting fluid 2 in the input pipe 3. When the temperature sensor 10 detects a temperature higher than the preset maximum value, the controller 14 activates the condenser 9 to cool the cutting fluid 2. When the laser particle counter 8 detects that the particle count in the cutting fluid 2 is lower than the preset value, the controller 14 activates the stirring motor 71 to stir the cutting fluid 2 in the storage container 1, or activates the solenoid valve to add or replace the cutting fluid 2 in the storage container 1. The pressure sensor 11 and flow sensor 12 can... The controller 14 monitors the flow rate and pressure parameters of the cutting fluid 2 in real time, and can adjust them according to different workpieces 16 and specific requirements. When the pressure parameter of the cutting fluid 2 needs to be adjusted, the controller 14 controls the pump speed of the adjustment drive 4 to adjust the pressure of the cutting fluid 2. When the flow rate of the cutting fluid 2 needs to be adjusted, the controller 14 controls the pump output power of the adjustment drive 4 to adjust the flow rate of the cutting fluid 2. When the cutting fluid 2 is injected into the workpiece 16, the impact force of the cutting fluid 2 thoroughly removes the residual iron filings inside the workpiece 16. At the same time, the cutting fluid 2 contains polishing particles. When the cutting fluid 2 washes over the inside of the workpiece 16, the polishing particles continuously rub against the inner surface of the workpiece 16, thereby reducing the roughness of the inner surface of the workpiece 16 and polishing the inside of the workpiece 16. This inhibits the shedding of metal powder from the inner surface of the workpiece 16, prevents media contamination and accidents, and achieves simultaneous chip removal and polishing.

[0054] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
