For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] like Figures 1-8As shown, a wear tester proposed by the present invention includes a support platform 100, a plurality of friction platforms 110 for placing samples are fixedly installed on the top of the support platform 100 by screws, and a fixing ring 130 for pressing and fixing the sample is connected to the outside of the friction platform 110 through a quick release mechanism 120. A through opening 150 communicating with an internal mounting cavity 140 of the platform is further provided on the surface of the support platform 100, and a support column 151 is inserted into the interior of the through opening 150. The top of the support column 151 is connected to a cover plate 300 through a hinge mechanism 200, and a plurality of friction components 310 for cooperating with the friction platform 110 to perform wear resistance tests on the sample are installed on the surface of the cover plate 300. A driving mechanism 400 for driving the support column 151 to move in the X-axis and Y-axis directions is installed inside the mounting cavity 140, and a control mechanism 500 is also installed inside the mounting cavity 140;

[0037] The hinge mechanism 200 includes a T-shaped plate 210 fixedly installed on the top of the support column 151. The top of the T-shaped plate 210 is rotatably connected to the U-shaped seat 230 at the bottom of the cover plate 300 through a limiting support mechanism 220. One end of the T-shaped plate 210 is hinged to one side of the cover plate 300 through an installed hinge 240.

[0038] Specifically, when testing the wear resistance of a sample, multiple friction tables 110 can be used to place the sample to be tested, and the quick-release mechanism 120 and the fixing ring 130 cooperate with each other to provide a convenient and efficient way to fix the sample. Then, the driving mechanism 400 drives the support column 151 to move in the X-axis and Y-axis directions to achieve different motion trajectories of the friction assembly 310 on the sample surface, thereby completing the wear resistance test. The control mechanism 500 is responsible for coordinating the operation of various components, receiving operating instructions and controlling the movement of the driving mechanism 400, while monitoring the operating status of the equipment to ensure that the entire test process is stable and accurate, thereby jointly building a complete and efficient wear resistance testing system.

[0039] When it is necessary to open the cover 300 to place or remove the sample, the cover 300 can be rotated open with the hinge 240 as the axis. During the rotation of the cover 300, the limiting support mechanism 220 on the top of the T-plate 210 cooperates with the U-shaped seat 230 at the bottom of the cover 300 to ensure the stability and smoothness of the rotation of the cover 300 while also supporting it. When the cover 300 is opened to a suitable angle, the locking head 225 cooperates with the locking block 227 with the locking groove 226 to stably limit the cover 300 to prevent it from shaking or accidentally closing, making it convenient for operators to perform sample operations safely and conveniently. After the test is completed, the cover 300 is smoothly closed by rotating the hinge mechanism 200, and the next test can be carried out.

[0040] In this embodiment, a control panel 160 is installed on the front of the support platform 100 , a display 161 with a touch operation function is installed on the surface of the control panel 160 , and a level 170 with a level ball is fixedly installed on one side of the support platform 100 .

[0041] Specifically, when using the wear tester, the operator adjusts the placement and angle of the instrument by observing the position of the level ball in the level 170 to ensure that the instrument is in a horizontal state, ensuring that the friction component 310 performs a uniform and accurate friction test on the sample surface, avoiding deviations in the test results due to tilting of the instrument, thereby ensuring the reliability and accuracy of the test data;

[0042] Then, the operator interacts with the instrument through the control panel 160 on the front of the support platform 100. The display 161 with touch operation function provides the operator with an intuitive and convenient operation interface. The operator can input test instructions on the display 161, and the instructions are transmitted to the control motherboard 510 of the control mechanism 500 through the circuit, thereby controlling the operation of the drive mechanism 400.

[0043] In this embodiment: the quick-release mechanism 120 includes a plurality of bosses 121 symmetrically fixedly connected to the outside of the friction platform 110, and the bosses 121 are connected in a guiding and sliding manner with arc-shaped guide grooves 122 correspondingly provided on the wall of the fixing ring 130. When the fixing ring 130 and the friction platform 110 are completely covered and sleeved, the bosses 121 slide to the end of one end of the arc-shaped guide groove 122.

[0044] Specifically, when performing the sample fixing operation, align the fixing ring 130 with the friction table 110, align the protrusions 121 symmetrically arranged on the outside of the friction table 110 with the arc-shaped guide grooves 122 correspondingly opened on the wall of the fixing ring 130, and then push the fixing ring 130, and the protrusions 121 slide along the arc-shaped guide grooves 122. As the fixing ring 130 moves, when the fixing ring 130 and the friction table 110 are completely covered and sleeved, the protrusions 121 slide to the end of one end of the arc-shaped guide grooves 122. At this time, the fixing ring 130 presses the sample tightly against The sample is quickly fixed on the friction table 110; compared with traditional screw fixation or complex snap-on structure, this fixing method is simple and quick to operate, greatly saving sample installation time, and during the test, the cooperation between the protruding column 121 and the arc-shaped guide groove 122 can effectively prevent the fixing ring 130 from displacement, ensuring the stability of the sample fixation and the accuracy of the test results. After the test is completed, the fixing ring 130 is pushed in the reverse direction, and the protruding column 121 slides out along the arc-shaped guide groove 122, and the fixing ring 130 can be quickly removed and the sample is taken out.

[0045] In this embodiment: the friction assembly 310 includes a sleeve 311 fixedly connected to the inside of the cover plate 300, a connecting rod 312 is inserted into the interior of the sleeve 311, a fixing sleeve 313 is fixedly connected to the middle of the connecting rod 312, the fixing sleeve 313 cooperates with a locking knob 314 threadedly connected to the top of the connecting rod 312 to lock the connecting rod 312 and the cover plate 300, and a detachable friction head 315 is threadedly connected to the bottom end of the connecting rod 312.

[0046] Specifically, when assembling the friction assembly 310 and the cover plate 300, the connecting rod 312 is first inserted into the sleeve 311. The connecting rod 312 can be firmly locked and fixed to the cover plate 300 through the fixing sleeve 313 provided in the middle of the connecting rod 312 and the locking knob 314 threadedly connected to the top. This not only ensures the stability of the connecting rod 312 during the test process, but also facilitates the replacement of friction heads 315 of different specifications according to different test requirements.

[0047] When conducting a wear resistance test, the driving mechanism 400 drives the support column 151 to move, and then drives the friction assembly 310 through the hinge mechanism 200 and the cover plate 300 to rub on the sample surface according to a set trajectory. According to different samples and test requirements, a friction head 315 of suitable material, shape and size can be selected to ensure the accuracy and effectiveness of the test results; after the test is completed, the friction head 315 can be easily disassembled for cleaning, maintenance or replacement.

[0048] In this embodiment, a protective cover 152 is fixedly connected to the top of the through opening 150 . The protective cover 152 is also disposed outside the support column 151 . The top of the protective cover 152 is also flush with the bottom of the T-shaped plate 210 .

[0049] Specifically, the protective cover 152 is arranged on the outside of the support column 151 to prevent dust, debris, etc. from entering the installation cavity 140, thereby preventing these foreign objects from damaging the drive mechanism 400 and other components, affecting the normal operation and test accuracy of the instrument. The top of the protective cover 152 is flush with the bottom of the T-plate 210, making the appearance of the entire instrument more neat and beautiful, and further enhancing the protection performance and structural stability of the instrument.

[0050] In this embodiment: the limiting support mechanism 220 includes two guide rails 221 fixedly connected to the top of the T-shaped plate 210, and the sliding grooves of the two guide rails 221 are slidably connected with sliding blocks 222 through guide rods, and the middle groove of the sliding block 222 is rotatably connected with a support rod 223 through a rotating shaft, one end of the support rod 223 is connected to a hinge seat 224 through a rotating shaft, and the hinge seat 224 is fixedly connected to the U-shaped seat 230, and the other end of the support rod 223 is fixedly connected to U-shaped locking heads 225 on both sides, and the inner side of one end of the two guide rails 221 is fixedly connected to a locking block 227 with a locking groove 226.

[0051] When the cover 300 is opened, the sliding blocks 222 fixedly connected to the two guide rails 221 at the top of the T-shaped plate 210 slide in the slide groove through the guide rod, driving the support rod 223 to move. As the cover 300 is rotated to open, the support rod 223 gradually extends. When the cover 300 is opened to a suitable angle, the U-shaped locking heads 225 on both sides of the other end of the support rod 223 cooperate with the locking blocks 227 with locking grooves 226 on the inner side of one end of the guide rail 221 to lock the support rod 223, thereby stabilizing the limit cover 300 and preventing it from shaking or accidentally closing. When closing the cover 300, the reverse operation is performed to release the lock, and the support rod 223 is retracted under the drive of the sliding blocks 222, so that the cover 300 is smoothly closed, ensuring the safety and stability of the opening and closing process of the cover 300, facilitating the operator to perform sample operation, while also protecting the instrument components and extending the service life of the instrument.

[0052] In this embodiment: the driving mechanism 400 includes a support seat 410 fixedly installed inside the mounting cavity 140, and a first linear screw module 420 for X-axial drive is installed on the top of the support seat 410, and a connecting seat 430 is fixedly installed on the top of the sliding block of the first linear screw module 420, and the bottom two sides of the connecting seat 430 are slidingly connected to the first guide rail 450 on the top of the support seat 410 through the installed first guide seat 440, and the top of the connecting seat 430 is fixedly installed with a second linear screw module 460 for X-axial drive, and the top of the sliding block of the second linear screw module 460 is fixedly connected to the bottom of the support column 151 through the connecting plate 470, and the bottom two sides of the connecting plate 470 are slidingly connected to the second guide rail 490 on the top of the connecting seat 430 through the installed second guide seat 480, and the outer sides of the connecting seat 430 and the connecting plate 470 are both installed with displacement sensors 4100.

[0053] Specifically, when conducting sample testing, the first linear screw module 420 is driven by the motor, and its sliding block can move along the screw in the X-axis direction, and the connecting seat 430 fixedly installed on the top of the sliding block moves accordingly, and the first guide seats 440 installed on both sides of the bottom of the connecting seat 430 are slidably connected to the first guide rail 450 on the top of the support seat 410, ensuring the smooth and accurate movement of the connecting seat 430; the second linear screw module 460 is also driven by the motor, and its sliding block drives the connecting plate 470 to move in the X-axis direction, and the second guide seats 480 on both sides of the bottom of the connecting plate 470 cooperate with the second guide rail 490 on the top of the connecting seat 430 to ensure the stable movement of the connecting plate 470;

[0054] The displacement sensor 4100 can monitor the displacement of the connecting plate 470 and the support column 151 in real time, and feed back the information to the control main board 510 of the control mechanism 500. The control main board 510 adjusts the operation of the driving mechanism 400 in time according to the feedback information to ensure that the support column 151 moves accurately according to the set trajectory, thereby realizing the composite movement of the support column 151 in the X-axis and Y-axis directions, meeting the diverse requirements of different wear resistance tests for the motion trajectory.

[0055] In this embodiment: the control mechanism 500 includes a control mainboard 510, which is installed inside the installation cavity 140. The control mainboard 510 is electrically connected to the motor, control panel 160 and displacement sensor 4100 of the drive mechanism 400 respectively. The control mainboard 510 is also electrically connected to an external power supply through a control switch 520 on the side of the support platform 100.

[0056] Specifically, the operator inputs test instructions, such as test time, motion trajectory parameters, etc., through the display 161 of the control panel 160. The instructions are transmitted to the control main board 510. The control main board 510 controls the operation of the motor of the drive mechanism 400 according to the instructions, drives the first linear screw module 420 and the second linear screw module 460, and realizes the X-axial and Y-axial movement of the support column 151. At the same time, the displacement sensor 4100 monitors the displacement of the connecting seat 430 and the connecting plate 470 in the drive mechanism 400 in real time, and feeds back the displacement information to the control main board 510. The control main board 510 adjusts the movement of the drive mechanism 400 in real time according to the feedback information to ensure the accuracy and stability of the movement.

[0057] A testing method for an abrasion tester, applied to any of the above abrasion testers, comprises the following steps:

[0058] S1, placing the sample on the friction table 110, and using the fixing ring 130 to press and fix the sample through the quick release mechanism 120;

[0059] S2, using the control panel 160 to input a test command, the control mechanism 500 controls the driving mechanism 400 to operate after receiving the command, driving the support column 151 to move in the X-axis and Y-axis directions;

[0060] S3, using the friction head 315 of the friction assembly 310 to rub the sample surface to perform a wear resistance test on the sample; S4, using the displacement sensor 4100 to monitor the displacement of the connecting seat 430 and the connecting plate 470 in the driving mechanism 400 in real time, and feeding back the displacement information to the control mechanism 500, and the control mechanism 500 adjusts the movement of the driving mechanism 400 based on the feedback information;

[0061] S5. After the test is completed, the driving mechanism 400 is stopped, the cover 300 is opened, the hinge mechanism 200 is used to rotate it, and the limit support mechanism 220 is used to limit the cover 300. Then, the fixing ring 130 is quickly removed and the sample is taken out.

[0062] Specifically, when conducting a wear resistance test, the sample is first placed on the friction table 110, and the quick release mechanism 120 is used to connect the convex column 121 with the guide sliding connection of the arc guide groove 122, and the fixed ring 130 is used to quickly press and fix the sample. Then, the operator uses the control panel 160 to input test instructions, such as setting the test time, selecting the motion trajectory, etc. After receiving the instructions, the control main board 510 of the control mechanism 500 controls the operation of the driving mechanism 400. The first linear screw module 420 and the second linear screw module 460 in the driving mechanism 400 are driven by the motor to drive the support column 151 to perform X-axial and Y-axial movements, and the cover plate 300 and the friction assembly 310 are driven to move through the hinge mechanism 200. The friction head 315 of the friction assembly 310 rubs on the sample surface according to the set trajectory to perform a wear resistance test on the sample. During the test, displacement sensor 4100 monitors the displacement of connecting seat 430 and connecting plate 470 in drive mechanism 400 in real time and feeds this information back to control mechanism 500. Control mechanism 500 adjusts the movement of drive mechanism 400 based on this feedback to ensure test accuracy and stability. Upon completion of the test, drive mechanism 400 is controlled to stop, and cover plate 300 is opened using hinge mechanism 200. Limiting support mechanism 220 then quickly removes retaining ring 130 and the sample, completing the test process.

[0063] It should be noted that the wear tester of the present invention can make the friction head 315 move according to the standard Lissajous figure trajectory through the cooperation of the first linear screw module 420, the second linear screw module 460 and the support column 151 in the driving mechanism 400. Specifically, the control main board 510 of the control mechanism 500 derives the velocity and acceleration equations of the X-axis and Y-axis according to the input Lissajous parameter equation (x(t)=asin(pt), y(t)=bsin(qt+ψ)), and then controls the pulse emission frequency of the servo motor. After the motion conversion of the motor and the screw, the connecting seat 430, the connecting plate 470 and the support column 151 are driven to perform a compound motion in the X-axis and Y-axis directions. At the same time, the displacement sensor 4100 monitors the displacement of the connecting seat 430 and the connecting plate 470 in real time and feeds back to the control main board 510 to correct the trajectory deviation, so that the friction component 310 on the cover plate 300 performs wear resistance testing on the sample on the friction table 110 according to the predetermined Lissajous curve trajectory, thereby realizing trajectory diversification and high-precision control.
