Description

Technical Field

[0001] This invention belongs to the field of cutting fluid friction testing technology, specifically referring to a cutting fluid friction reliability testing device. Background Technology

[0002] Cutting fluid plays a crucial role in metal cutting, rapidly forming a stable lubricating film at the tiny interfaces between the tool, workpiece, and chips. This film acts as a highly efficient barrier, effectively reducing direct friction between the tool, workpiece, and chips, thus significantly lowering the cutting forces required and the resulting power consumption. Furthermore, cutting fluid effectively inhibits built-up edge formation, preventing increased surface roughness caused by built-up edge and significantly improving surface finish. Simultaneously, the reduced friction and cutting forces greatly slow down tool wear, thereby extending tool life.

[0003] Current cutting fluid friction reliability testing equipment has the following problems:

[0004] Existing cutting fluid friction reliability testing equipment lacks the capability to test the lubricity of cutting fluid during workpiece machining. It cannot guarantee the lubrication performance of the cutting fluid on the workpiece and tool, and it cannot promptly extract the waste cutting fluid and replenish it with new cutting fluid when the lubrication performance deteriorates, leading to a reduction in workpiece machining quality. Furthermore, it cannot integrate cutting fluid testing with workpiece machining. Therefore, it cannot meet the usage requirements of existing cutting fluid friction reliability testing equipment. Summary of the Invention

[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a cutting fluid friction reliability testing device that can integrate cutting fluid testing with workpiece machining, test the lubricity of the cutting fluid during workpiece machining, ensure the lubrication performance of the cutting fluid, and guarantee the machining quality of the workpiece.

[0006] The technical solution adopted in this plan is as follows: This plan proposes a cutting fluid friction reliability testing device, including a cutting frame, a test frame, a fluid-changing friction testing mechanism, and a fluid-replenishing lubrication mechanism. The test frame is installed on the bottom wall of the cutting frame. The fluid-changing friction testing mechanism includes a grinding component, a circulation component, a guiding component, and a sliding component. The grinding component is installed on the upper wall of the cutting frame, the circulation component is installed on the test frame, the guiding component is installed on the inner wall of the test frame inside the circulation component, and the sliding component is installed on the outer side of the guiding component. The fluid-replenishing lubrication mechanism includes a waste liquid component and a fluid-adding component. The waste liquid component is installed on one end of the bottom wall of the cutting frame, and the fluid-adding component is installed on the end of the bottom wall of the cutting frame away from the waste liquid component.

[0007] As a further preferred embodiment of the present invention, the grinding assembly includes a grinding cylinder, a grinding motor, and a grinding cutter head. The grinding cylinder is located on the upper wall of the cutting frame and has an open top. The grinding motor is located on the bottom wall of the grinding cylinder. The grinding cutter head is rotatably located at the bottom of the grinding cylinder, and the power end of the grinding motor passes through the grinding cylinder and connects to the grinding cutter head. The circulation assembly includes a circulation pump, a filter box, a filter tube, a crossflow tube, and a circulation pipe. The circulation pump is located on one side of the test frame, and the discharge end of the circulation pump passes through the test frame and communicates with the filter box. The filter boxes are symmetrically arranged on the inner side walls at both ends of the test frame. The crossflow tube is located between the filter boxes, and the filter tube is connected between the filter box and the crossflow tube. The circulation pipe passes through the test frame. The guide assembly includes a sliding shaft, a sliding groove, and an anti-slip layer. The sliding shaft is located between the filter boxes inside the crossflow tube. Multiple sets of the sliding grooves are located outside the sliding shaft and are open at one end. The anti-slip layer is located on the inner wall of the sliding groove. The push-slide assembly includes a sliding seat, a flow groove, a sliding magnet, a push-slide electromagnet, and a magnetic proximity switch. The sliding seat is slidably located inside the sliding groove. The flow groove is located inside the sliding seat and is through-type. The sliding magnet is located outside the sliding seat. The push-slide electromagnets are symmetrically located on the side walls of the filter boxes at both ends of the crossflow tube. The magnetic proximity switches are symmetrically located on the upper wall of the test frame below the crossflow tube.

[0008] During use, it is necessary to ensure the lubricity of the cutting fluid during the workpiece grinding process to ensure the grinding quality of the workpiece. The cutting fluid is injected into the grinding cylinder. The circulation pump draws the cutting fluid injected into the grinding cylinder into the crossflow tube through the circulation pipe at the suction end. The circulation pipe delivers the cutting fluid through the filter tube into the crossflow tube through the filter box. The cutting fluid is continuously injected into the grinding cylinder. As the cutting fluid fills the crossflow tube, the cutting fluid in the crossflow tube flows back into the grinding cylinder from the circulation pipe at the end away from the circulation pump. When the cutting fluid submerges the upper wall of the grinding disc, the injection of cutting fluid into the grinding cylinder is stopped.

[0009] When the push-sliding electromagnet at the end of the crossflow tube near the sliding magnet is energized, it repels the sliding magnet due to the same pole. The push-sliding electromagnet fixed to the side wall of the filter box pushes the sliding magnet through the repulsive force. The sliding magnet drives the sliding seat to slide along the slide groove to the other end of the slide groove. The sliding seat stops moving after being blocked. At this time, the sliding magnet reaches the magnetic proximity switch at the other end of the sliding shaft. The magnetic proximity switch senses the sliding magnet, thereby causing the push-sliding electromagnets at both ends of the sliding shaft to be alternately energized to drive the sliding magnet. The operator records the time interval between when the sliding magnet slides from one end of the slide groove to the other end of the magnetic proximity switch under the same magnetic field strength. This time is the initial unidirectional sliding time of the sliding seat along the anti-slip layer.

[0010] The grinding motor drives the grinding disc to rotate through the power end. The operator fixes the workpiece to be ground on the positioning structure. The positioning structure causes the workpiece to contact the grinding disc. The rotating grinding disc performs grinding operations on the workpiece. The circulating cutting fluid lubricates the grinding disc and the workpiece. As the grinding time of the grinding disc on the workpiece increases, the lubrication performance of the circulating cutting fluid gradually decreases, affecting the grinding effect of the grinding disc on the workpiece and reducing the workpiece processing quality.

[0011] After the crossflow tube is filled with cutting fluid, the frictional resistance between the sliding seat and the anti-slip layer is reduced under the lubrication of the cutting fluid. This shortens the interval of the sliding seat sliding unidirectionally along the anti-slip layer, making it easier to test and monitor the lubrication performance of the cutting fluid used in grinding, thereby ensuring the reliability of the cutting fluid in grinding operations.

[0012] Preferably, the waste liquid assembly includes a waste liquid cylinder, a waste liquid metering pump, a waste liquid pipe, and a one-way inlet valve. The waste liquid cylinder is located on the bottom wall of one end of the cutting frame, the waste liquid metering pump is located on the upper wall of the waste liquid cylinder, and the discharge end of the waste liquid metering pump extends through the inside of the waste liquid cylinder. The waste liquid pipe connects the suction end of the waste liquid metering pump located at the end of the cutting frame away from the circulation pump with the circulation pipe. The one-way inlet valve connects the outside of the circulation pipe between the waste liquid pipe and the grinding cylinder. The liquid filling assembly includes a liquid filling cylinder, a liquid filling metering pump, and a liquid filling pipe. The liquid filling cylinder is located on the bottom wall of the end of the cutting frame away from the waste liquid cylinder, the liquid filling metering pump is located on the side wall of the liquid filling cylinder, and the suction end of the liquid filling metering pump extends through the inside of the liquid filling cylinder. The liquid filling pipe connects the grinding cylinder with the discharge end of the liquid filling metering pump.

[0013] During use, when the interval of sliding along the anti-slip layer of the sliding seat tends to be similar to its initial unidirectional sliding time, it indicates that the lubrication performance of the cutting fluid has decreased and its reliability has reduced. At this time, the waste liquid metering pump intercepts the waste cutting fluid that flows back to the grinding cylinder through the waste liquid pipe via the suction end. The waste cutting fluid is then pumped into the waste liquid cylinder for storage through the waste liquid pipe. At the same time, the liquid addition metering pump draws the cutting fluid from the liquid addition cylinder through the suction end. The cutting fluid enters the grinding cylinder through the liquid addition pipe to ensure the lubrication performance of the cutting fluid when the grinding head is grinding the workpiece, thereby ensuring the machining quality of the workpiece.

[0014] Specifically, the side wall of the cutting frame is equipped with a controller.

[0015] The controller is electrically connected to the grinding motor, the magnetic proximity switch, the waste liquid metering pump, and the liquid addition metering pump.

[0016] The beneficial effects achieved by this solution using the above structure are as follows:

[0017] Compared with existing technologies, this solution combines a fluid-changing friction testing mechanism with a fluid-replenishing lubrication mechanism. Through the setting of grinding components, circulation components, guiding components, sliding components, waste fluid components, and fluid replenishment components, it can test and monitor the reliability of cutting fluid during workpiece grinding. On the one hand, it ensures the grinding quality of the workpiece by the grinding head; on the other hand, it can replace and replenish the cutting fluid in a timely manner during the processing to ensure the lubrication performance of the cutting fluid. Furthermore, the waste fluid pipe can intercept the waste fluid flowing back into the processing area, and the fluid replenishment pipe can restore and maintain the effective component concentration of the cutting fluid in the processing area, thereby ensuring the reliability of the cutting fluid during workpiece processing.

The circulation pump 9 is located on one side of the test frame 2. The discharge end of the circulation pump 9 passes through the test frame 2 and connects to the filter box 10. The filter boxes 10 are symmetrically arranged on the inner side walls at both ends of the test frame 2. The crossflow tube 12 is located between the filter boxes 10.

Between the grinding cylinder 5 and the liquid extraction end of the circulating pump 9; the guide assembly 14 includes a sliding shaft 15, a sliding groove 16 and an anti-slip layer 17. The sliding shaft 15 is located between the filter boxes 10 inside the crossflow tube 12. Multiple sets of the sliding grooves 16 are located outside the sliding shaft 15 and are open at one end. The anti-slip layer 17 is located on the inner wall of the sliding groove 16. The push-slide assembly 18 includes a sliding seat 19, a liquid flow channel 20, a sliding magnet 21, a push-slide electromagnet 22 and a magnetic proximity switch 24. The sliding seat 19 is slidably located inside the sliding groove 16. The liquid flow channel 20 is located inside the sliding seat 19 and is through-connected.

[0034] The waste liquid assembly 26 includes a waste liquid cylinder 27, a waste liquid metering pump 28, a waste liquid pipe 29, and a one-way inlet valve 30. The waste liquid cylinder 27 is located on the bottom wall of one end of the cutting frame 1. The waste liquid metering pump 28 is located on the upper wall of the waste liquid cylinder 27, with its discharge end penetrating inside the waste liquid cylinder 27. The waste liquid pipe 29 connects the suction end of the waste liquid metering pump 28, located at the end of the cutting frame 1 away from the circulation pump 9, to the circulation pipe 13. The one-way inlet valve 30... The circulation pipe 13 is connected to the outside of the waste liquid pipe 29 and the grinding cylinder 5; the liquid addition assembly 31 includes a liquid addition cylinder 32, a liquid addition metering pump 33 and a liquid addition pipe 34. The liquid addition cylinder 32 is located on the bottom wall of the cutting frame 1 away from the waste liquid cylinder 27.

The liquid addition metering pump 33 has its liquid drawing end penetrating inside the liquid addition cylinder 32. The liquid addition pipe 34 is connected between the grinding cylinder 5 and the liquid addition metering pump 33.

[0035] The side wall of the cutting frame 1 is equipped with a controller 23.

[0036] The controller 23 is electrically connected to the grinding motor 6, the magnetic proximity switch 24, the waste liquid metering pump 28, and the liquid addition metering pump 33, respectively.

[0037] In practical applications, during the workpiece grinding process, it is necessary to ensure the lubricity of the cutting fluid to guarantee the grinding quality of the workpiece.

[0038] Before the cutting fluid is injected into the crossflow tube 12, the sliding resistance of the sliding seat 19 is at its maximum due to the anti-slip layer 17 on the inner wall of the chute 16. The controller 23 controls the push-sliding electromagnet 22 at one end of the crossflow tube 12 to generate magnetism. The push-sliding electromagnet 22 and the sliding magnet 21 are set with the same pole. The push-sliding electromagnet 22 is fixed to the side wall of the filter box 10 at one end of the crossflow tube 12. The push-sliding electromagnet 22 pushes the sliding magnet 21 through repulsion. The sliding magnet 21 drives the sliding seat 19 to slide along the chute 16 to the end of the chute 16. The sliding seat 19 stops moving due to the obstruction. At this time, the sliding magnet 21 reaches the magnetic proximity switch 24 above the end of the sliding shaft 15 away from the energized push-sliding electromagnet 22. The magnetic proximity switch 24 senses the sliding magnet 21. The controller 23 controls the push-sliding electromagnet 22 at the end of the crossflow tube 12 away from the sliding magnet 21. 2. Power off and demagnetize. The push-sliding electromagnet 22 at the end of the crossflow tube 12 near the sliding magnet 21 is energized. The push-sliding electromagnet 22 is fixed to the side wall of the filter box 10 and pushes the sliding magnet 21 through repulsion. The sliding magnet 21 drives the sliding seat 19 to slide along the slide groove 16 to the other end of the slide groove 16. The sliding seat 19 stops moving after being blocked. At this time, the sliding magnet 21 reaches the magnetic proximity switch 24 at the other end of the sliding shaft 15. The magnetic proximity switch 24 senses the sliding magnet 21, so that the push-sliding electromagnets 22 at both ends of the sliding shaft 15 are alternately energized to drive the sliding magnet 21. The operator records the time interval of the sliding magnet 21 sliding from the magnetic proximity switch 24 at one end of the slide groove 16 to the magnetic proximity switch 24 at the other end of the slide groove 16 under the drive of the same magnetic field. This is the time of the initial unidirectional sliding of the sliding seat 19 along the anti-slip layer 17.

[0039] The operator injects cutting fluid into the grinding cylinder 5. The controller 23 controls the circulation pump 9 to start. The circulation pump 9 draws the cutting fluid from the grinding cylinder 5 through the circulation pipe 13 via the suction end. The cutting fluid first enters the filter box 10 and is filtered by the filter cotton. Then it is transported to the cross flow pipe 12 through the filter pipe 11. The cutting fluid is continuously injected into the grinding cylinder 5. As the cutting fluid fills the cross flow pipe 12, the cutting fluid in the cross flow pipe 12 flows back into the grinding cylinder 5 from the circulation pipe 13 at the end away from the circulation pump 9. When the cutting fluid submerges the upper wall of the grinding disc 7, the injection of cutting fluid into the grinding cylinder 5 is stopped.

[0040] After the crossflow tube 12 is filled with cutting fluid, the frictional resistance between the sliding seat 19 and the anti-slip layer 17 is reduced under the lubrication of the cutting fluid. Under the push of the same magnetic field, the sliding interval of the sliding magnet 21 from one end of the slide groove 16 to the other end is shortened. A portion of the cutting fluid flows from the space between the sliding magnet 21 and the wall of the crossflow tube 12, while another portion flows from inside the flow tank 20. The cutting fluid flowing inside the flow tank 20 can replace the cutting fluid between the sliding seat 19 and the anti-slip layer 17 in a timely manner, so that the cutting fluid participating in the grinding operation lubricates the sliding seat 19 and the anti-slip layer 17. This facilitates the testing and monitoring of the lubrication performance of the cutting fluid used in grinding, thereby ensuring the reliability of the cutting fluid in the grinding operation.

[0041] The controller 23 controls the grinding motor 6 to start, and the grinding motor 6 drives the grinding disc 7 to rotate through the power end. The operator fixes the workpiece to be ground on the positioning structure. The positioning structure causes the workpiece to contact the grinding disc 7. The rotating grinding disc 7 performs grinding operations on the workpiece. The circulating cutting fluid lubricates the grinding disc 7 and the workpiece.

[0042] As the grinding time of the grinding head 7 on various workpieces increases, the lubrication performance of the circulating cutting fluid decreases, affecting the grinding effect of the grinding head 7 on the workpiece and reducing the workpiece machining quality. When the interval time of the sliding seat 19 along the anti-slip layer 17 from the magnetic proximity switch 24 at one end of the slide groove 16 to the magnetic proximity switch 24 at the other end of the slide groove 16 tends to be the initial unidirectional sliding time of the sliding seat 19 along the anti-slip layer 17, it indicates that the lubrication performance of the cutting fluid has decreased and its reliability has decreased. At this time, the controller 23 controls the waste liquid metering pump 28 to start. The waste liquid metering pump 28 uses waste liquid through the pumping end. Part 26 intercepts the cutting fluid flowing back into the grinding cylinder 5 from the circulation pipe 13. The waste cutting fluid is pumped into the waste liquid cylinder 27 through the waste liquid pipe 29 for storage. At the same time, the controller 23 controls the start of the liquid metering pump 33. The liquid metering pump 33 draws the cutting fluid from the liquid filling cylinder 32 through the suction end. The cutting fluid enters the grinding cylinder 5 through the liquid filling pipe 34. The amount of waste liquid drawn by the waste liquid metering pump 28 is consistent with the flow rate of the cutting fluid added by the liquid metering pump 33, thereby ensuring the reliability and lubricity of the recycled cutting fluid in the grinding process. The above operation can be repeated for the next use.

[0044] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
