Description

Technical Field

[0001] This application relates to the technical field of testing machines, and in particular to a friction and wear testing machine with a multi-mode testing module. Background Technology

[0002] As a specialized testing device, the core function of the friction and wear testing machine is to simulate the wear behavior of materials under different friction conditions such as sliding and rolling. By quantitatively measuring key parameters such as friction coefficient and wear amount, it can evaluate the wear resistance, friction characteristics and service life of materials. It is widely used in materials research and development, industrial quality inspection and other fields.

[0003] In actual testing, due to varying testing requirements, friction and wear tests need to cover multiple modes, including sliding friction, rolling friction, and reciprocating sliding friction. However, in existing technologies, most testing machines can only perform a single test mode for the sample, resulting in the need to configure multiple different types of testing machines to complete multi-mode tests. This not only increases equipment purchase costs but also occupies more installation space.

[0004] To meet different testing needs, improved solutions have been proposed in related technologies. For example, Chinese patent CN218896022U provides a dual-mode material friction and wear testing device, which includes a mounting frame and a clamp. The mounting frame can be detachably equipped with a translation mechanism or a rotation mechanism. Depending on different testing needs, the translation mechanism or the rotation mechanism can be selected, thereby realizing the switching of multiple testing modes of a single device.

[0005] However, in the aforementioned technologies, the replacement of translational and rotational mechanisms requires manual operation, and the machine needs to be stopped during the replacement process, which reduces the testing efficiency. Therefore, a testing machine is needed that can meet the testing requirements and improve testing efficiency. Summary of the Invention

[0006] To improve the testing efficiency of friction and wear testing machines, this application provides a friction and wear testing machine with a multi-mode testing module.

[0007] This application provides a friction and wear testing machine with a multi-mode testing module, which adopts the following technical solution:

[0008] A friction and wear testing machine with a multi-mode testing module includes a support frame, an upper sample mechanism, a lower sample mechanism, a material changing mechanism, and a receiving component; The lower sample mechanism includes a lower sample clamping member and a lower sample driving assembly; the lower sample driving assembly is disposed on the support frame, and the lower sample clamping member is disposed on the lower sample driving assembly; the lower sample driving assembly is used to drive the lower sample clamping member to move, so that the lower sample clamping member drives the lower sample to move and rotate in the horizontal plane and rotate in the vertical plane; the lower sample clamping member is used to clamp the lower sample. The upper sample mechanism is used to move the upper sample to contact the lower sample. The receiving assembly is mounted on the support frame and is used to place the upper and lower samples. The material changing mechanism includes a material changing clamping assembly and a material changing drive assembly; the material changing drive assembly is disposed on the support frame, and the material changing clamping assembly is disposed on the material changing drive assembly; the material changing drive assembly drives the material changing clamping assembly to move, so that after the material changing clamping assembly picks up the upper sample and the lower sample from the receiving assembly, it feeds them onto the upper sample mechanism and the lower sample clamping member respectively.

[0009] By adopting the above technical solution, the upper sample mechanism drives the upper sample to contact the lower sample, and the lower sample driving component drives the lower sample to move and rotate in the horizontal plane and rotate in the vertical plane, thereby realizing multi-mode friction and wear testing, improving the problem that different test mechanisms need to be changed for different tests in the existing technology, and improving test efficiency.

[0010] Meanwhile, the material changing mechanism can automatically complete the loading and unloading of upper and lower samples, thereby improving the problem of needing to manually stop the machine to change samples after the test is completed, and further improving the test efficiency.

[0011] Optionally, the material changing clamping assembly includes an upper sample changing component and a lower sample changing component; both the upper sample changing component and the lower sample changing component are disposed on the material changing drive assembly. The material changing drive assembly drives the upper sample changing component and the lower sample changing component to move closer or further apart from each other, so that the upper sample changing component feeds or removes material from the upper sample, and the lower sample changing component feeds or removes material from the upper sample.

[0012] By adopting the above technical solution, the material changing clamping assembly is equipped with an upper sample changing component and a lower sample changing component. With the help of the material changing drive assembly, the two components are driven to move closer or further apart, so that the upper sample and the lower sample can be loaded or unloaded respectively, thereby meeting the sample changing requirements and improving the test efficiency.

[0013] Optionally, the material changing drive assembly includes an upper support plate, a lower support plate, a material changing lifting component, and a material changing translation component; the material changing translation component is disposed on the support frame, and the material changing lifting component is disposed on the material changing translation component; the upper sample material changing component is disposed on the upper support plate, and the lower sample material changing component is disposed on the lower support plate; both the upper support plate and the lower support plate are disposed on the material changing lifting component; the material changing lifting component is used to drive the upper support plate and the lower support plate to move closer to or further away from each other.

[0014] By adopting the above technical solution, with the cooperation of the material changing translation component and the material changing lifting component, after the material changing translation component drives the upper sample clamping component and the lower sample clamping component to move horizontally to the designated position, the material changing lifting component drives the upper support plate and the lower support plate to move closer or further away from each other, so that the upper sample clamping component can move closer to the upper sample and the lower sample clamping component can move closer to the lower sample, thereby completing the picking or loading of the upper and lower samples.

[0015] Optionally, the lower sample driving assembly includes a translational driving component, a first rotational driving component, a second rotational driving component, a connecting seat, a third rotational driving component, and a rotating seat; The translation drive is mounted on the support frame, and the first rotation drive is mounted on the translation drive. The translation drive is used to drive the first rotation drive to move in the horizontal plane. The connecting seat is mounted on the first rotation drive member, and the first rotation drive member is used to drive the connecting seat to rotate in the horizontal plane; The second rotation drive member is disposed on the connecting seat, the rotating seat is rotatably disposed on the connecting seat, and the second rotation drive member is used to drive the rotating seat on the connecting seat to perform vertical plane rotation; The third rotation drive is mounted on the rotating base, and the lower sample clamp is mounted on the third rotation drive.

[0016] By adopting the above technical solution, the first translational drive component drives the first rotational drive component to move horizontally, allowing the lower sample to move horizontally; the first rotational drive component drives the connecting seat to rotate horizontally, allowing the lower sample to rotate horizontally; the second rotational drive component drives the rotating seat on the connecting seat to rotate vertically; and the third rotational drive component drives the lower sample clamping component to rotate, allowing the lower sample to rotate vertically. Through the cooperation of the first translational drive component, the first rotational drive component, the second rotational drive component, the connecting seat, the third rotational drive component, and the rotating seat, the movement and rotation of the lower sample in the horizontal plane and the rotation in the vertical plane are realized, thus making it suitable for different testing modes.

[0017] Optionally, the receiving component includes an upper sample placement rack and a lower sample placement rack; the upper sample placement rack is connected to the lower sample placement rack, the lower sample placement rack is disposed on the support frame, the upper sample placement rack is used to place the upper sample, and the lower sample placement rack is used to place the lower sample.

[0018] By adopting the above technical solution, the upper sample placement rack and the lower sample placement rack can hold the upper sample and the lower sample respectively, which facilitates the accurate material handling by the material changing mechanism, further reduces manual intervention, and improves test efficiency.

[0019] Optionally, the receiving assembly further includes a receiving component; both the upper sample placement rack and the lower sample placement rack are provided with a receiving component, which is used to clamp the upper sample or the lower sample.

[0020] By adopting the above technical solution, receiving components are set on the upper and lower sample placement racks. The receiving components can fix the upper or lower sample, which facilitates the material changing mechanism to accurately pick up the material and ensures the accuracy and stability of the test.

[0021] Optionally, a measuring component is also included, comprising a measuring drive and a measuring element. The measuring drive is mounted on the support frame, and the measuring element is mounted on the measuring drive. The measuring drive is used to drive the measuring element to move vertically, and the measuring element is used to detect wear on the lower sample.

[0022] By adopting the above technical solution, the measuring tool can measure parameters such as the depth, width, and area of ​​the wear marks on the surface of the sample, thereby quantitatively assessing the degree of wear of the sample.

[0023] Optionally, there are two receiving components, namely a first receiving component and a second receiving component; the first receiving component is used to place the upper sample and the lower sample to be tested; the second receiving component is used to place the upper sample and the lower sample after the test is completed; after the material changing clamping component takes the material from the first receiving component, it moves to the position of the upper sample mechanism and the lower sample mechanism to load the material; after the material changing clamping component unloads the upper sample and the lower sample, it moves to the position of the second receiving component to release the material.

[0024] By adopting the above technical solution and setting up a first receiving component and a second receiving component, it is easier for the material changing mechanism to move to the designated position for picking up and discharging materials, reducing manual intervention, improving the automation level of the testing machine, and thus improving testing efficiency.

[0025] Optionally, two material changing clamping components are provided, namely a first material changing clamping component and a second material changing clamping component; when the first material changing clamping component picks up material from the first receiving component, the second material changing clamping component unloads material at the positions of the upper sample mechanism and the lower sample mechanism; when the first material changing clamping component loads material at the positions of the upper sample mechanism and the lower sample mechanism, the second material changing clamping component releases material at the position of the second receiving component.

[0026] By adopting the above technical solution, the first material changing clamping component removes the upper and lower samples to be tested from the position of the first receiving component. When the material is being removed, the second material changing clamping component is simultaneously positioned at the positions of the upper and lower sample mechanisms to remove the tested upper and lower samples, thus completing the unloading process.

[0027] When the first material changing clamping assembly moves the upper and lower samples to be tested to the positions of the upper and lower sample mechanisms, and drives the upper sample to move onto the upper sample mechanism and the lower sample to move onto the lower sample mechanism, the second material changing clamping assembly moves synchronously to the position of the second receiving assembly, and places the upper and lower samples that have completed the test onto the second receiving assembly, thus completing the unloading.

[0028] By cooperating with the first and second material changing clamping components, material changing can be performed without stopping the machine. At the same time, the first and second material changing clamping components work synchronously, which shortens the material changing time and further improves the material changing efficiency, thereby improving the test efficiency.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. The upper sample mechanism drives the upper sample to contact the lower sample, and the lower sample driving component drives the lower sample to move and rotate in the horizontal plane and rotate in the vertical plane, thereby realizing multi-mode friction and wear testing, improving the problem that different test mechanisms need to be changed for different tests in the existing technology, and improving test efficiency; Meanwhile, the material changing mechanism can automatically complete the loading and unloading of upper and lower samples, thereby improving the problem of needing to manually stop the machine to change samples after the test is completed, and further improving the test efficiency.

Through the cooperation of the first translation drive, the first rotation drive, the second rotation drive, the connecting seat, the third rotation drive and the rotating seat, the movement and rotation of the lower sample in the horizontal plane and the rotation in the vertical plane are realized, thus making it suitable for different test modes;

[0031] 3. By setting up receiving components, the upper sample placement rack and the lower sample placement rack can hold the upper sample and the lower sample respectively, which facilitates the accurate material picking by the material changing mechanism, further reduces manual intervention and improves test efficiency.

[0034] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0035] Example 1 Embodiment 1 of this application discloses a friction and wear testing machine with a multi-mode testing module. For example... Figure 1 As shown, the friction and wear testing machine includes a support frame 1, an upper sample mechanism 2, a lower sample mechanism 3, and a measuring component 6.

[0036] Specifically, such as Figure 1 As shown, the upper sample mechanism 2 includes an upper sample holder 21 and an upper sample drive 22. In this embodiment 1, the upper sample drive 22 is a linear module, and the upper sample holder 21 is a clamp used to hold the upper sample. The body of the upper sample drive 22 is fixedly connected to the support frame 1, and the output end of the upper sample drive 22 is fixedly connected to the upper sample holder 21. The upper sample drive 22 can drive the upper sample holder 21 to move in the vertical direction.

[0037] like Figure 1As shown, the lower sample mechanism 3 includes a lower sample driving assembly 32, a support platform 33, and a test module. In this embodiment 1, the lower sample driving assembly 32 is a linear module. The body of the lower sample driving assembly 32 is fixedly connected to the support frame 1, and the output end of the lower sample driving assembly 32 is fixedly connected to the support platform 33. The support platform 33 is used to install the test module, and the lower sample driving assembly 32 can drive the support platform 33 to move horizontally. The test module includes a translational friction module 34, a rotational friction module 35, and a ring-block friction module 36.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the translational friction module 34 includes a translational drive component 341, a translational mounting base 342, and a translational test base 343. The body of the translational drive component 341 is fixedly connected to the translational mounting base 342, and the output end of the translational drive component 341 is fixedly connected to the translational test base 343. Preferably, the translational drive component 341 is a linear module. The translational mounting base 342 is fixed to the support platform 33 by bolts, making the translational friction module 34 detachably connected to the support platform 33. A pressure block 344 is installed on the translational test base 343, and the pressure block 344 is connected to the translational test base 343 by bolts. During the test, rotating the bolts causes the pressure block 344 to press the lower sample tightly onto the translational test base 343, reducing the possibility of the lower sample moving and thus improving the accuracy of the test.

[0039] like Figure 3 and Figure 4 As shown, the rotating friction module 35 includes a rotating mounting base 351, a rotating drive device 352, and a rotating test stand 353. The rotating drive device 352 includes a motor, a transmission belt, and a pulley. The motor body is fixedly mounted on the rotating mounting base 351. The rotating test stand 353 is fixedly connected to the pulley, and the pulley is rotatably connected to the rotating mounting base 351. The motor drives the pulley to rotate via the transmission belt, causing the rotating test stand 353 to rotate. During the test, the lower sample is fixedly mounted on the rotating test stand 353, allowing the lower sample to rotate. Furthermore, the rotating mounting base 351 is detachably connected to the support platform 33, facilitating the replacement of the test module.

[0040] like Figure 5 As shown, the ring block friction module 36 includes a ring block mounting base 361 and a ring block drive component 362. The ring block mounting base 361 is fixed to the support platform 33 by bolts, thereby making the ring block mounting base 361 detachably connected to the support platform 33. The body of the ring block drive component 362 is fixedly connected to the ring block mounting base 361. When the lower sample is a ring block, the ring block is sleeved and fixed on the output end of the ring block drive component 362, thereby enabling the ring block drive component 362 to drive the ring block to rotate.

[0041] like Figure 1As shown, the measurement component 6 includes a measurement drive 61 and a measurement component 62. The body of the measurement drive 61 is fixedly connected to the support frame 1, and the output end of the measurement drive 61 is fixedly connected to the measurement component 62. In this embodiment 1, the measurement drive 61 is a linear module, and the measurement component 62 is a 3D laser scanner. The measurement drive 61 can drive the measurement component 62 to move in the vertical direction, thereby facilitating the measurement of the wear amount on the surface of the lower sample.

[0042] The implementation principle of a friction and wear testing machine with a multi-mode testing module in Embodiment 1 of this application is as follows: When an experiment is required, the translational friction module 34, the rotational friction module 35, or the ring-block friction module 36 are selected according to the experimental requirements. The test module is then installed on the support platform 33. At the same time, the lower sample is installed on the corresponding test module, and the upper sample is installed on the upper sample holder 21.

[0043] After the test module is installed, the upper sample drive component 22 drives the upper sample to contact the lower sample, thereby conducting a friction and wear test.

[0044] When the translational friction module 34 is installed to conduct the translational friction test, the translational drive component 341 and the lower sample drive component 32 cooperate to make the lower sample move in two horizontal directions, thereby conducting the translational friction test.

[0045] When the rotating friction module 35 is installed to conduct the rotating friction test, the rotating drive device 352 drives the rotating test seat 353 to rotate on the base, thereby conducting the rotating friction test.

[0046] When the ring block friction module 36 is installed to conduct the ring block friction test, the ring block drive component 362 drives the ring block to rotate, thereby conducting the ring block friction test.

[0047] Embodiment 1 of this application improves the versatility of the friction and wear testing machine by replacing different test modules to meet different test requirements, thereby reducing test costs and saving test space.

[0048] Example 2 Embodiment 2 of this application provides a friction and wear testing machine with a multi-mode testing module, such as... Figure 6 As shown, the testing machine includes a support frame 1, an upper sample mechanism 2, a lower sample mechanism 3, a material changing mechanism 4, and a receiving component 5.

[0049] Specifically, such as Figure 6 and Figure 7As shown, the upper sample mechanism 2 includes an upper sample clamping member 21 and an upper sample driving member 22. In this embodiment 2, the upper sample driving member 22 is a linear module, and the upper sample clamping member 21 is an electric chuck. The upper sample clamping member 21 is used to clamp the upper sample. The body of the upper sample driving member 22 is fixedly connected to the support frame 1, and the output end of the upper sample driving member 22 is fixedly connected to the upper sample clamping member 21. The upper sample driving member 22 can drive the upper sample clamping member 21 to move in the vertical direction, thereby moving the upper sample in the vertical direction.

[0050] like Figure 7 As shown, the lower sample mechanism 3 includes a lower sample clamping member 31 and a lower sample driving assembly 32. Preferably, the lower sample clamping member 31 is an electric chuck, so that the lower sample clamping member 31 can clamp lower samples of different shapes, such as discs and ring blocks.

[0051] Among them, such as Figure 7 and Figure 8 As shown, the lower sample driving assembly 32 includes a translational drive 321, a first rotational drive 322, a second rotational drive 323, a connecting seat 324, a third rotational drive 325, and a rotating seat 326. The body of the translational drive 321 is fixedly connected to the support frame 1. The output end of the translational drive 321 is fixedly connected to the body of the first rotational drive 322, and the output end of the first rotational drive 322 is fixedly connected to the connecting seat 324. The body of the second rotational drive 323 is fixedly connected to the connecting seat 324, and the output end of the second rotational drive 323 is fixedly connected to the rotating seat 326. The rotating seat 326 is rotatably connected to the connecting seat 324. The body of the third rotational drive 325 is fixedly connected to the rotating seat 326, and the output end of the third rotational drive 325 is fixedly connected to the lower sample clamping member 31.

[0052] In this embodiment 2, the translation drive 321 is a two-axis linear module. The translation drive 321 can drive the first rotation drive 322 to move in two directions on the horizontal plane, so that the lower sample can move in two directions on the horizontal plane, thereby performing a translational friction test. The first rotation drive 322 is a motor, which can drive the connecting seat 324 to rotate on the horizontal plane, so that the lower sample can rotate on the horizontal plane, thereby performing a rotational friction test. The second rotation drive 323 is a motor, which can drive the rotating seat 326 to rotate on the connecting seat 324. At the same time, the third rotation drive 325 is also a motor, which can drive the lower sample holder 31 to rotate relative to the rotating seat 326. Through the cooperation of the second rotation drive 323, the third rotation drive 325 and the rotating seat 326, the lower sample holder 31 can rotate in the vertical plane, so that the lower sample can rotate in the vertical plane, thereby performing a ring-block friction test. Embodiment 2 of this application, through the lower sample mechanism 3, can meet the friction test under multiple test modes, improve the versatility of the testing machine, and enhance the test efficiency.

[0053] like Figure 6 and Figure 9 As shown, the material changing mechanism 4 includes a material changing clamping assembly 41 and a material changing drive assembly 42. The material changing clamping assembly 41 includes an upper sample changing component 411 and a lower sample changing component 412. The material changing drive assembly 42 includes an upper support plate 421, a lower support plate 422, a material changing lifting component 423, and a material changing translation component 424. Preferably, the upper sample changing component 411 is an electric chuck, and the lower sample changing component 412 is an electric chuck. The body of the upper sample changing component 411 is fixedly connected to the upper support plate 421, and the body of the lower sample changing component 412 is fixedly connected to the lower support plate 422.

[0054] Specifically, such as Figure 6 and Figure 9 As shown, the body of the material changing translation component 424 is fixedly connected to the support frame 1, and the output end of the material changing translation component 424 is fixedly connected to the body of the material changing lifting component 423. The upper support plate 421 and the lower support plate 422 are both mounted on the material changing lifting component 423. In this embodiment 2, the material changing translation component 424 is a linear module, which can drive the material changing lifting component 423 to move horizontally; the material changing lifting component 423 is a linear module, which can drive the upper support plate 421 and the lower support plate 422 to move closer to or further away from each other in the vertical direction.

[0055] like Figure 6As shown, the receiving assembly 5 includes an upper sample placement rack 51, a lower sample placement rack 52, and a receiving component 53. Both the upper sample placement rack 51 and the lower sample placement rack 52 are fixedly connected to the support frame 1, and a receiving component 53 is fixedly connected to both the upper sample placement rack 51 and the lower sample placement rack 52. Preferably, the receiving component 53 is an electric chuck.

[0056] In addition, such as Figure 6 As shown, the measurement component 6 includes a measurement drive 61 and a measurement component 62. The body of the measurement drive 61 is fixedly connected to the support frame 1, and the output end of the measurement drive 61 is fixedly connected to the measurement component 62. In this embodiment 1, the measurement drive 61 is a linear module, and the measurement component 62 is a 3D laser scanner. The measurement drive 61 can drive the measurement component 62 to move in the vertical direction, thereby facilitating the measurement of the wear amount on the surface of the lower sample.

[0057] It should be noted that, as Figure 6 As shown, in this embodiment 2, two receiving components 5 are provided, namely the first receiving component 501 and the second receiving component 502. The first receiving component 501 is used to place the upper and lower samples to be tested, and the second receiving component 502 is used to place the upper and lower samples after the friction test. During the test, the tester places the upper and lower samples to be tested on the receiving part 53 of the first receiving component 501. At this time, the material changing translation component 424 moves the upper sample changing component 411 and the lower sample changing component 412 to the position of the first receiving component 501. Then, the material changing lifting component 423 drives the upper support plate 421 and the lower support plate to move, so that the upper sample changing component 411 and the lower sample changing component 412 move away from each other, thus facilitating the upper sample changing component 411 to hold the upper sample and the lower sample changing component 412 to hold the lower sample, completing the material removal.

[0058] After the material is picked up, with the cooperation of the material changing translation component 424 and the material changing lifting component 423, the upper sample changing component 411 moves the upper sample to the position of the upper sample clamping component 21, and the lower sample changing component 412 moves the lower sample to the position of the lower sample clamping component 31, thereby completing the loading of the upper and lower samples.

[0059] After the material is loaded, the material changing drive component 42 drives the upper sample changing component 411 and the lower sample changing component 412 back to the position of the first receiving component 501, providing space for the upper sample mechanism 2 and the lower sample mechanism 3 to conduct the test.

[0060] After the test is completed, the material changing drive assembly 42 drives the upper sample changing component 411 and the lower sample changing component 412 to move, so that the upper sample changing component 411 removes the upper sample from the upper sample clamping component 21, and the lower sample changing component 412 removes the lower sample from the lower sample clamping component 31, thus completing the unloading.

[0061] After the material is unloaded, the material changing drive assembly 42 moves the upper sample changing component 411 and the lower sample changing component 412 to the position of the second receiving assembly 502. At this time, the receiving component 53 of the upper sample placement rack 51 of the second receiving assembly 502 clamps the upper sample of the upper sample changing component 411, and the receiving component 53 of the lower sample placement rack 52 clamps the lower sample of the lower sample changing component 412, completing the unloading and making it convenient for the test personnel to take away.

[0062] After the test is completed, the upper and lower test samples are placed in the second receiving component 502. The material changing drive component 42 drives the material changing clamping component 41 back to the position of the first receiving component 501 to conduct the next set of upper and lower test samples.

[0063] Embodiment 2 of this application reduces manual operation and improves the automation level of the test by setting up a material changing mechanism 4 and a receiving component 5, thereby improving the problem of needing to stop the machine to change the sample and improving the test efficiency.

[0064] The implementation principle of a friction and wear testing machine with a multi-mode testing module in Embodiment 2 of this application is as follows: Before the test, the test personnel placed the upper sample on the upper sample placement rack 51 of the first receiving component 501 and the lower sample on the lower sample placement rack 52 of the first receiving component 501.

[0065] After the sample is placed on the first receiving component 501, the material changing translation component 424 drives the material changing mechanism 4 to move the position of the first receiving component 501. Then, the material changing lifting component 423 drives the upper support plate 421 and the lower support plate 422 to move away from each other, so that the upper sample changing component 411 removes the upper sample to be tested, and the lower sample changing component 412 removes the lower sample to be tested.

[0066] After the upper and lower test specimens are removed from the first receiving assembly 501, the upper specimen is moved to be held by the upper specimen clamping member 21 and the lower specimen is moved to be held by the lower specimen clamping member 31, driven by the material changing drive assembly 42. Then, the material changing clamping assembly 41 returns to the position of the first receiving assembly 501, and the friction test begins.

[0067] During the test, after the upper and lower samples have completed friction, the lower sample driving assembly 32 drives the lower sample holder 31 to move, causing the lower sample to move to the position of the measuring assembly 6 for scanning of the lower sample surface. After scanning is completed, the lower sample driving assembly 32 drives the lower sample back to directly below the upper sample.

[0068] After the lower sample returns to directly below the upper sample, the material changing drive assembly 42 drives the material changing clamping assembly 41 to move, removing the upper sample from the upper sample clamping member 21 and the lower sample from the lower sample clamping member 31. The upper and lower samples are then moved to the position of the second receiving assembly 502 and placed on it. Simultaneously, the tester places the next set of upper and lower samples to be tested on the first receiving assembly 501.

[0069] After the upper and lower test samples are placed on the second receiving component 502, the material changing drive component 42 drives the material changing clamping component 41 back to the position of the first receiving component 501 to conduct the test on the next set of test samples.

[0070] Example 3 The difference between Embodiment 3 and Embodiment 2 of this application is as follows: like Figure 10 , Figure 11 and Figure 12 As shown, in this embodiment 3, the material changing translation component 424 is a two-axis linear module. The body of the material changing translation component 424 is fixedly mounted on the support frame 1. The output end of the material changing translation component 424 is fixedly connected to the body of the material changing lifting component 423. The material changing translation component 424 can drive the material changing lifting component 423 to move in two directions on the horizontal plane, so that the lower sample changing component 412 and the upper sample changing component 411 can move in two directions on the horizontal plane. In addition, there are two material changing clamping components 41, namely the first material changing clamping component 401 and the second material changing clamping component 402.

[0071] After the test is completed, the material changing translation component 424 drives the first material changing clamping assembly 401 and the second material changing clamping assembly 402 to move simultaneously, so that the second material changing clamping assembly 402 is directly below the upper sample mechanism 2. At this time, the first material changing clamping assembly 401 is in the position of the first receiving assembly 501. Then, the material changing lifting component 423 drives the upper support plate 421 and the lower support plate 422 to move simultaneously, so that the second material changing clamping assembly 402 can remove the upper sample from the upper sample clamping assembly 21 and the lower sample from the lower sample clamping assembly 31, completing the unloading. At the same time, the first material changing clamping assembly 401 removes the upper and lower samples to be tested from the first receiving assembly 501, completing the unloading. By cooperating with the first material changing clamping assembly 401 and the second material changing clamping assembly 402, after the second material changing clamping assembly 402 removes the upper and lower samples after the test is completed, the first material changing clamping assembly 401 simultaneously removes the next set of upper and lower samples to be tested from the first receiving assembly 501, thereby improving material changing efficiency.

[0072] After the first material changing clamping assembly 401 removes the upper and lower samples to be tested from the first receiving assembly 501, the material changing translation component 424 drives the second material changing clamping assembly 402 to move to the position of the second receiving assembly 502. At this time, the first material changing clamping assembly 401 moves directly below the upper sample mechanism 2. Then, driven by the material changing lifting component 423, the upper sample to be tested moves to the position of the upper sample clamping component 21 and is clamped, and the lower sample to be tested moves to the position of the lower sample clamping component 31 and is clamped, completing the loading. At the same time, the second material changing clamping assembly 402 places the tested upper and lower samples on the second receiving assembly 502, completing the unloading.

[0073] After the upper sample to be tested is installed on the upper sample mechanism 2 and the lower sample is installed on the lower sample mechanism 3, the material changing drive assembly 42 drives the first material changing clamping assembly 401 and the second material changing clamping assembly 402 to move in the horizontal plane toward the side away from the upper sample mechanism 2 and the lower sample mechanism 3, so as to provide test space for the test.

[0074] The implementation principle of a friction and wear testing machine with a multi-mode testing module in Embodiment 3 of this application is as follows: Driven by the material changing drive assembly 42, the second material changing clamping assembly 402 removes the completed upper sample from the upper sample mechanism 2 and the completed lower sample from the lower sample mechanism 3. At this time, the first material changing clamping assembly 401 can simultaneously remove the next set of upper and lower samples to be tested from the first receiving assembly 501.

[0075] After the upper and lower test specimens are removed from the first receiving assembly 501, the second material changing clamping assembly 402 moves to the position of the second receiving assembly 502 under the drive of the material changing drive assembly 42. At the same time, the first material changing clamping assembly 401 moves to the positions of the upper test specimen mechanism 2 and the lower test specimen mechanism 3. Then, under the drive of the material changing lifting component 423, the second material changing clamping assembly 402 places the tested upper and lower test specimens on the second receiving assembly 502. Simultaneously, the first material changing clamping assembly 401 synchronously installs the upper test specimen to be tested on the upper test specimen clamping component 21 and synchronously installs the lower test specimen to be tested on the lower test specimen clamping component 31, thereby completing the specimen replacement.

[0076] After the sample replacement is completed, the material replacement drive assembly 42 drives the first material replacement clamping assembly 401 and the second material replacement clamping assembly 402 to move away from the upper sample mechanism 2 and the lower sample mechanism 3, thereby leaving test space so that the upper sample mechanism 2 can drive the upper sample to perform a friction test with the lower sample on the lower sample mechanism 3.

[0077] After the test is completed, the material changing drive assembly 42 drives the second material changing clamping assembly 402 to move towards the upper sample mechanism 2 and the lower sample mechanism 3, so that the second material changing clamping assembly 402 is between the upper sample clamping member 21 and the lower sample clamping member 31. At the same time, the first material changing clamping assembly 401 is in the position of the first receiving assembly 501 to change the next set of samples.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
