Description

Technical Field

[0001] This utility model belongs to the field of particle friction technology, specifically relating to a test bench for surface friction of energetic particles. Background Technology

[0002] Particle friction is crucial for the ubiquitous accumulation and flow phenomena in nature and industrial production, such as geological faulting, powder mixing and densification, and particle flow lubrication. The coefficient of friction (COF) is expressed as the tangential friction force divided by the total normal force and is usually used to describe the shear strength of particle systems. Currently, particle friction research is mainly related to two experimental schemes: the surface sliding scheme, in which shear elements slide along the surface of the particle system, and the internal sliding scheme, in which shear elements slide inside the particle system.

[0003] To date, surface sliding schemes have been widely used in particle friction research due to their simplicity;

[0004] To address these issues, a test bench for surface friction of energetic particles was designed. Utility Model Content

[0027] Example 1

[0028] like Figure 1 As shown;

[0029] A surface friction test bench for energetic particles includes a workbench housing 1 and a workbench plate 11 disposed on the surface of the workbench housing 1.

[0030] Furthermore:

[0031] like Figures 1 to 5 As shown:

[0032] In conjunction with the above, the workbench 11 also includes a base plate 24 fixedly connected to the surface of the workbench 11. The surface of the base plate 24 is slidably connected to a mounting block 2 via a slider and slide rail mechanism 241. A sample block 21 is mounted on the surface of the mounting block 2, and a sample pin 3 is provided above the sample block 21.

[0033] In this implementation scheme: Since the surface of the workbench 11 is provided with a base plate 24, the mounting block 2 slides on the base plate 24 through the slider slide rail mechanism 241, and the surface of the mounting block 2 is equipped with a sample block 21. With this design, the operator can move the position of the mounting block 2 to make the sample block 21 rub against the sample pin 3, thereby recording data.

[0034] It should be noted that the sample block 21 is mounted on the surface of the mounting block 2 by bolts, which facilitates subsequent replacement.

[0035] Furthermore:

[0036] In an optional embodiment, a mounting housing 22 is fixedly connected to the surface of the base plate 24, and a guide strip 221 is fixedly connected to the surface of the mounting housing 22. The guide strip 221 passes through the surface of the mounting block 2 and is slidably connected to the mounting block 2.

[0037] In this embodiment: because a guide bar 221 is provided, the guide bar 221 provides guidance for the sliding of the mounting block 2, ensuring the stability and straightness of the mounting block 2 during the sliding process, avoiding deviation during sliding, thereby improving the accuracy of the friction test results.

[0038] Furthermore:

[0039] In an optional embodiment, support plates 23 are provided on both sides of the mounting housing 22. The two support plates 23 are fixedly connected to the surface of the workbench 11, and a lever mechanism support 44 is installed on the upper surface of the support plate 23. The lever mechanism body 4 is rotatably connected to the inner side of the lever mechanism support 44, and the sample pin 3 is installed on the surface of the lever mechanism body 4 by adjusting bolts.

[0040] In this embodiment, the lever mechanism body 4 can apply different magnitudes of force to the sample pin 3 using the lever principle, which facilitates friction tests under different load conditions.

[0041] Furthermore:

[0042] In an optional embodiment, a load cantilever 42 is fixedly connected to one end of the lever mechanism body 4, a weight hook 43 is slidably connected to the surface of the load cantilever 42, and a balance weight 41 is connected to the side of the lever mechanism body 4 away from the load cantilever 42 via a slide rod 45.

[0043] In this embodiment: by hanging weights of different specifications on the weight hook 43 and changing the position of the weights by sliding the weight hook 43 on the load cantilever 42, the load acting on the lever mechanism body 4 can be easily adjusted. The balancing weight 41 is used to balance the lever mechanism body 4, ensuring the stability of the lever mechanism body 4 during the test, making the force applied to the sample pin 3 more accurate and stable, and ensuring the reliability of the test results.

[0044] It should be noted that the surface of the slide bar 45 is threaded, and the balance weight 41 is threadedly connected to the slide bar 45.

[0045] Furthermore:

[0046] In an optional embodiment, a friction sensor 25 is disposed inside the mounting housing 22. One end of the friction sensor 25 is fixedly connected to the mounting block 2 via a fixing rod 26, and a connecting rod 27 is fixedly connected to the end of the friction sensor 25 away from the fixing rod 26.

[0047] In this embodiment: During the experiment, the frictional force generated by the movement of the mounting block 2 is transmitted to the friction sensor 25 through the fixing rod 26. The friction sensor 25 converts the frictional force signal into an electrical signal, which is convenient for measurement and recording, and provides key data for studying the frictional characteristics of the surface of energetic particles.

[0048] It should be noted that these electrical signals can be transmitted to external signal acquisition and processing equipment, such as data acquisition cards or specialized measuring instruments, via data cables connected to the sensors. Operators can directly read the friction-related electrical signal data on the displays of these devices, or transmit the data to a computer for further analysis and processing.

[0049] Furthermore:

[0050] In an optional embodiment, an electric cylinder 5 and a servo motor 53 for driving the electric cylinder 5 are installed on the inner side of the workbench housing 1. The output shaft of the servo motor 53 is driven by the electric cylinder 5 through a transmission mechanism 52. A moving platform 51 is installed on the surface of the electric cylinder 5. A connecting plate 55 is fixedly connected to the surface of the moving platform 51. The surfaces of the workbench plate 11 and the base plate 24 are both provided with movable grooves for the moving of the connecting plate 55. The connecting plate 55 is fixedly connected to the connecting rod 27.

[0051] In this embodiment, the servo motor 53 precisely controls the operation of the electric cylinder 5, which drives the moving platform 51 and the connecting plate 55 to move, and then drives the mounting block 2 to slide through the connecting rod 27, thereby realizing an automated friction test process. Compared with manual operation, this improves test efficiency and accuracy, and has strong repeatability.

[0052] It should be noted that the transmission mechanism 52 can be a synchronous belt pulley assembly or other similar mechanism.

[0053] Furthermore:

[0054] In an optional embodiment, a displacement sensor 54 is provided on one side of the electric cylinder 5. The displacement sensor 54 is installed inside the workbench housing 1 and is connected to the mobile platform 51 via a connecting bracket 56.

[0055] In this embodiment, the displacement sensor 54 monitors the displacement of the moving platform 51 in real time and provides feedback on the moving distance of the mounting block 2 during the test, which facilitates the control of the test stroke and provides displacement parameters for accurate analysis of friction test data.

[0056] It should be noted that, similarly, the electrical signal is transmitted to the signal acquisition device through the corresponding line. The operator can obtain the electrical signal data of the moving distance of the mounting block 2 from the device to understand the displacement changes during the test.

[0057] Furthermore:

[0058] In an optional embodiment, an infrared thermometer 61 for measuring the temperature of the friction test is mounted on the surface of the workbench 11 via a temperature measuring frame 6.

[0059] In this embodiment: During the friction test, the infrared thermometer 61 can measure the temperature change of the friction area in real time. Temperature is an important factor affecting the surface friction characteristics of energetic particles, and provides necessary temperature data for a comprehensive study of their friction performance.

[0060] Working Principle: The worktable 11 has a base plate 24. The mounting block 2 slides on the base plate 24 via a slider-rail mechanism 241. A sample block 21 is mounted on the surface of the mounting block 2. With this design, the operator can move the mounting block 2 to cause friction between the sample block 21 and the sample pin 3, thereby recording data. A guide bar 221 guides the sliding of the mounting block 2, ensuring its stability and straightness during sliding and preventing deviation, thus improving the accuracy of the friction test results. The lever mechanism body 4 can apply different magnitudes of force to the sample pin 3 using the lever principle, facilitating friction tests under different load conditions. By hanging weights of different specifications on the weight hook 43 and changing the weight position by sliding the weight hook 43 on the load cantilever 42, the load applied to the lever mechanism body 4 can be easily adjusted. The balancing weight 41 is used to balance the lever mechanism body 4, ensuring its stability during the test and ensuring the force applied to the sample pin 3 is applied correctly. The force applied is more accurate and stable, ensuring the reliability of the test results. During the test, the friction force generated by the movement of the mounting block 2 is transmitted to the friction sensor 25 through the fixed rod 26. The friction sensor 25 converts the friction force signal into an electrical signal, which is convenient for measurement and recording, providing key data for studying the friction characteristics of energetic particle surfaces. The servo motor 53 precisely controls the operation of the electric cylinder 5, which drives the moving platform 51 and the connecting plate 55 to move, and then drives the mounting block 2 to slide through the connecting rod 27, realizing an automated friction test process. Compared with manual operation, it improves test efficiency and accuracy, and has strong repeatability. The displacement sensor 54 monitors the displacement of the moving platform 51 in real time and provides feedback on the moving distance of the mounting block 2 during the test, which is convenient for controlling the test stroke and provides displacement parameters for accurate analysis of friction test data. During the friction test, the infrared thermometer 61 can measure the temperature change of the friction area in real time. Temperature is an important factor affecting the friction characteristics of energetic particle surfaces, providing necessary temperature data for comprehensive study of its friction performance.
