Description

Technical Field

[0001] This application relates to the field of wear detection equipment technology, and more specifically, to a device for assisting in the detection of the reciprocating friction and wear performance of diamond lubricating oil. Background Technology

[0002] Diamond lubricant is a new type of lubricant that uses nano-sized diamond particles as the core additive. Through surface modification technology (such as silylation reaction) or emulsion dispersion technology, diamond is uniformly suspended in the base oil. The nano-sized diamond particles form a "structural film" on the surface of the friction pair, which transforms sliding friction into rolling friction, reduces the coefficient of friction, and can fill the surface of the friction pair, change the surface roughness of the friction pair, reduce wear debris caused by friction, and thus reduce sludge formation.

[0003] Existing devices for testing the performance of diamond lubricating oils only measure the coefficient of friction between two friction blocks using sensors during testing, thereby determining the performance parameters and wear and tear status of the diamond lubricating oil. This function is relatively limited and cannot comprehensively test other properties of the lubricating oil.

[0004] Therefore, we propose a device for assisting in the testing of the reciprocating friction and wear performance of diamond lubricating oil to solve the existing problems. Utility Model Content

[0032] like Figures 1 to 8As shown, a device for assisting in the testing of the reciprocating friction and wear performance of diamond lubricating oil includes a support 2, an oil reservoir 3 inside the support 2, a grinding groove 1 mounted on the top surface of the support 2, a sampling component 8 connected between the grinding groove 1 and the oil reservoir 3, a fixing component 5 on the grinding groove 1, a grinding plate 13 clamped between the fixing component 5 and the grinding groove 1, a driving component 6 mounted above the grinding groove 1, a clamping component 7 driven to the driving component 6, and a grinding block detachably mounted at one bottom end of the clamping component 7. In use, diamond lubricating oil is added to the grinding groove 1, and the fixing component 5 on the grinding groove 1 is used to clamp and mount the grinding plate 13, immersing the grinding plate 13 in the diamond lubricating oil as a primary contact surface for wear testing. The driving component 6 mounted above the grinding groove 1 provides power to drive the grinding plate 13. The moving clamping assembly 7 reciprocates to hold the grinding block, enabling it to reliably and stably rub against the grinding plate 13 in the diamond lubricant during the test. One end of the grinding block is detachably connected to the clamping assembly 7, facilitating the replacement of grinding blocks of different materials or shapes to change the coefficient of friction and conduct multiple tests with different parameters. During the test, by adjusting parameters such as the speed of the driving assembly 6 and the downward pressure of the clamping assembly 7, the friction state between the grinding block and the grinding plate 13 under different working conditions can be simulated to evaluate the friction and wear performance of the diamond lubricant under different conditions. After the test, the diamond lubricant is sampled by the sampling assembly 8 to detect the material information in the sludge generated by friction, thereby determining the friction and wear performance of the diamond lubricant.

[0033] Furthermore, the bottom of the grinding tank 1 is provided with at least two sampling holes 11 penetrating the grinding tank 1. The sampling assembly 8 includes at least two sampling tubes 81 communicating with the sampling holes 11 and a suction pump 82 fixedly installed at the bottom of the grinding tank 1. One end of the bottom of the sampling tube 81 is provided with a first connecting pipe 812. The suction pump 82 is provided with a second connecting pipe 821 communicating with the first connecting pipe 812. The bottom of the suction pump 82 is provided with a third connecting pipe 822 communicating with the oil storage tank 3. In use, the suction pump 82 generates suction force on the diamond lubricating oil, causing the diamond lubricating oil to enter the sampling tube 81 through the sampling holes 11 for filtration. The filtered diamond lubricating oil flows sequentially through the second connecting pipe 821 and the third connecting pipe 822 under the action of the suction pump 82 and is recovered into the oil storage tank 3.

[0034] Furthermore, the sampling tube 81 is detachably connected to the sampling port 11, and the first connecting tube 812 and the second connecting tube 821 are detachably connected. In use, it is convenient to remove the sampling tube 81 to collect the sludge sample collected in the sampling tube 81 for testing.

[0035] Furthermore, a filter screen 811 is installed in the sampling tube 81 to filter and separate the diamond lubricating oil and the sludge generated after grinding for sampling.

[0036] Furthermore, a first piston 12 is provided on the sampling hole 11. During use, the first piston 12 is sealed to the sampling hole 11 during the testing process to prevent the diamond lubricating oil in the grinding tank 1 from leaking. When sampling, the first piston 12 is removed so that the grinding tank 1 is connected to the sampling tube 81 through the sampling hole 11 for sampling.

[0037] Furthermore, the drive assembly 6 includes two sets of first reciprocating motion modules 61 arranged along the length direction of the grinding groove 1. A synchronization assembly 62 is provided between the two sets of first reciprocating motion modules 61. A second reciprocating motion module 63 is slidably connected to the two sets of first reciprocating motion modules 61. The second reciprocating motion module 63 is arranged along the width direction of the grinding groove 1 and a clamping assembly 7 is slidably connected to the second reciprocating motion module 63. In use, the first reciprocating motion module 61 and the second reciprocating motion module 63 are used to drive the clamping assembly 7 to reciprocate above the grinding groove 1. The grinding block installed on the clamping assembly 7 rubs against the grinding plate 13 arranged in the grinding groove 1, thereby detecting the performance of the diamond lubricating oil in the grinding groove 1.

[0038] Furthermore, the clamping assembly 7 includes a pressure driver 71 disposed perpendicular to the end face of the grinding tank 1. The output end of the bottom of the pressure driver 71 is driven to connect to a base 72. A gripper 73 is mounted on the base 72. The gripper 73 is clamped to the grinding block. In use, by controlling the stroke of the output end of the bottom of the pressure driver 71, the pressure applied by the grinding block clamped on the gripper 73 to the grinding plate 13 disposed in the grinding tank 1 can be changed. This allows for the detection of friction loss of diamond lubricating oil under various pressures.

[0039] Furthermore, the fixing component 5 includes a fixing plate 51, which is disposed above the grinding tank 1 and fixedly connected at one end to the side wall of the grinding tank 1. The fixing plate 51 is provided with a movable rod 52 that can slide through the fixing plate 51. One end of the movable rod 52 that passes through the bottom of the fixing plate 51 is connected to a pressure plate 54. A spring 53 is fitted on the movable rod 52 and is disposed between the pressure plate 54 and the bottom surface of the fixing plate 51. In use, the grinding plate 13 is placed in the grinding tank 1, and the spring 53 applies a spring force downward to the fixing plate 51, which cooperates with the end face of the grinding tank 1 to clamp and fix the grinding plate 13, making the installation or replacement of the grinding plate 13 more convenient and efficient.

[0040] Furthermore, a connector 4 is provided between the grinding tank 1 and the oil storage tank 3, which is used to collect and recover the remaining diamond lubricating oil in the grinding tank 1 into the oil storage tank 3 after the test is completed.

[0041] Furthermore, the end face of the grinding tank 1 is also provided with a drain port 14 that penetrates the grinding tank 1. The communicating vessel 4 includes a communicating pipe 41 and a communicating valve 42. One end of the communicating pipe 41 is connected to the drain port 14, and the other end is equipped with the communicating valve 42. The other end of the communicating valve 42 is connected to the oil storage tank 3. A second piston 15 is provided on the drain port 14. During use, the second piston 15 is sealed to the drain port 14 during the testing process to prevent the diamond lubricating oil from leaking. After the test is completed, the second piston 15 is pulled out and the communicating valve 42 is opened to connect the grinding tank 1 and the oil storage tank 3 through the communicating vessel 4. The diamond lubricating oil flows into the oil storage tank 3 through the communicating vessel 4 for recycling.

[0042] The working principle of this utility model is as follows: During testing, the grinding plate 13 is installed in the grinding tank 1, with the size of the grinding plate 13 matching that of the grinding tank 1. The grinding plate 13 is clamped by the fixing component 5. Diamond lubricating oil is added to the grinding tank 1, ensuring that the diamond lubricating oil covers the grinding plate 13. A grinding block is installed on the jaws 73 at the bottom of the clamping component 7, and the length of the output end of the downward drive 71 is adjusted so that the jaws 73 drive the grinding block into the diamond lubricating oil and abut against the grinding plate 13. The driving component 6 drives the clamping component 7 to reciprocate, simulating the friction state between the two components under actual working conditions. Friction occurs between the grinding block and the grinding plate 13, and the diamond lubricating oil provides lubrication. After the friction time required for wear detection is reached, the driving component 6 is turned off, and the grinding block and grinding plate 13 are disassembled. The wear and loss status and mass of the grinding block and grinding plate 13 are detected and recorded. Parameters such as surface roughness are used as reference data for evaluating the friction and wear performance of diamond lubricating oil. Simultaneously, sludge generated by friction is sampled and tested. The first piston 12 on the sampling hole 11 is opened, and the suction pump 82 is started, allowing the diamond lubricating oil in the grinding tank 1 to enter the sampling tube 81 through the sampling hole 11. The filter screen 811 in the sampling tube 81 filters and separates impurities such as sludge from the lubricating oil. Under the action of the suction pump 82, the filtered lubricating oil flows sequentially through the second connecting pipe 821 and the third connecting pipe 822, and is finally recovered into the oil storage tank 3. The sampling tube 81 is detachably connected to the sampling hole 11, and the first connecting pipe 812 and the second connecting pipe 821 are also detachably connected, facilitating the removal of the sampling tube 81 after sampling to collect the sludge sample for further testing and analysis. Based on the test data, the friction and wear performance of the diamond lubricating oil is analyzed and evaluated.

[0043] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
