Description

Technical Field

[0001] This invention relates to the field of wear resistance testing technology for wear-resistant steel rings, and more specifically, to a device and method for testing the wear resistance performance of wear-resistant steel rings. Background Technology

[0002] Wear-resistant steel rings are ring-shaped components made primarily of high-strength wear-resistant steel. Due to their excellent wear resistance, wear-resistant steel rings are widely used in various industrial equipment and machinery as core components embedded in various bearings to reduce friction loss and ensure rotational accuracy.

[0003] Currently, when wear-resistant steel rings are used as the inner rings in bearings, the steel rings are mainly subjected to wear caused by the rolling elements that are in direct contact with them. During high-speed rotation, the rolling elements form continuous rolling friction with the inner ring raceway, which can easily lead to surface fatigue wear. Therefore, in the actual production process, after a batch of steel rings is produced, it is necessary to conduct sampling tests to test whether their wear resistance meets the production standards.

[0004] The current method for testing the wear resistance of steel rings involves simulating contact wear through sliding friction between the sample and a rotating disk, followed by measuring the wear amount using a surface profilometer, and then outputting a data test report.

[0005] However, existing testing devices mainly test the wear resistance of steel rings under the same working conditions through reciprocating motion. During the testing process, the placement state of the steel ring is not changed, and the process of testing the wear resistance of steel rings under different working conditions is lacking. The test results lack comprehensiveness and are not sufficiently relevant to the process production. This paper proposes a wear resistance testing device and method for wear-resistant steel rings to improve the existing problems. Summary of the Invention

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0045] Please see Figures 1-13 The present invention provides the following technical solutions:

[0046] Example 1, see Figure 1 In order to address the problem that existing tests lack comprehensiveness and are not sufficiently relevant to the production process, a wear-resistant steel ring wear resistance testing device is proposed to solve the related problems. The wear resistance testing device includes a testing component 1, a placement component 2 is arranged above the testing component 1, and a steel ring 3 is arranged in the middle of the placement component 2.

[0047] The test component 1 enables the testing of the steel ring 3, and the placement component 2 enables the clamping of the steel ring 3. In practical applications, the produced steel ring 3 is first sampled, and then the reciprocating wear resistance performance of the steel ring 3 can be tested by the cooperation of the test component 1 and the placement component 2.

[0048] The specific structure of test component 1 is as follows:

[0049] See Figure 2 and Figure 3The test assembly 1 includes a workbench 11, a support 12 is provided on the top of the workbench 11, a first electric slide rail 13 is provided on one side of the support 12, a second electric slide rail 14 is provided on the side of the first electric slide rail 13 away from the support 12, and a test mechanism 15 is provided on the side of the second electric slide rail 14 away from the first electric slide rail 13.

[0050] See Figure 2 and Figure 3 A mounting plate 18 is provided on one side of the second electric slide rail 14. A fixed seat 19 is provided on the side of the mounting plate 18 away from the second electric slide rail 14. A drive motor 16 is provided in the middle of the fixed seat 19. The output end of the drive motor 16 is connected to the test mechanism 15.

[0051] In practical applications, starting the first electric slide rail 13 causes the second electric slide rail 14, mounting plate 18, drive motor 16, fixed seat 19, and testing mechanism 15 to move horizontally. Starting the second electric slide rail 14 causes the mounting plate 18, drive motor 16, fixed seat 19, and testing mechanism 15 to move vertically. The horizontal and vertical movements allow for the adjustment of the position of the testing mechanism 15, facilitating the normal operation of subsequent testing of the steel ring 3 by the testing mechanism 15.

[0052] In actual testing, the testing mechanism 15 needs to simulate actual working conditions. Therefore, in practical applications, the specific structure of the testing mechanism 15 needs to be designed. The specific structure of the testing mechanism 15 is as follows:

[0053] See Figures 8-10 The testing mechanism 15 includes a first test piece 156 and a second test piece 157 disposed opposite to the first test piece 156.

[0054] See Figures 8-10 The testing mechanism 15 also includes an active component 151, which is connected to the output end of the drive motor 16. A driven component 152 is provided on one side of the active component 151, and the driven component 152 meshes with the active component 151. A support frame 155 is provided on the same side of the driven component 152 and the active component 151.

[0055] The follower 152 is hinged to the support frame 155. The support frame 155 is an irregular structure. A fixing plate is provided at the middle position between the support frame 155 and the mounting plate 18. One end of the fixing plate is connected to the mounting plate 18, and the other end of the fixing plate is connected to the support frame 155.

[0056] The driving member 151 and the driven member 152 are incomplete gear structures, with the toothed sides of the driving member 151 and the driven member 152 meshing. When the drive motor 16 is started, the drive motor 16 drives the driving member 151 to rotate, and then the driving member 151 drives the driven member 152 to follow its movement.

[0057] The driven member 152 and the support frame 155 are connected by a fixed rod, so that the driven member 152 and the support frame 155 are kept in a hinged state.

[0058] In addition, by setting a fixed plate to connect the support frame 155 and the mounting plate 18, the position of the support frame 155 can be limited, so that the clamping operation of the test mechanism 15 can be carried out normally.

[0059] See Figures 8-10 A first mounting rod 158 is provided on each side of the support frame 155. The two first mounting rods 158 are slidably connected to the support frame 155. A first connecting rod 153 is provided at the end of the two first mounting rods 158. The first connecting rod 153 is fixedly connected to the two first mounting rods 158 respectively. The end of the first connecting rod 153 is slidably connected to the driven member 152. A first test piece 156 is provided at the bottom of the first connecting rod 153.

[0060] The driven member 152 extends to the side away from the toothed part and is provided with a first connecting part. The first connecting part and the driven member 152 are integrally formed. The first connecting rod 153 is provided with a first sliding groove. A first sliding rod is provided at the middle position of the first connecting part and the first sliding groove on the first connecting rod 153. One end of the first sliding rod is fixedly connected to the first connecting part, and the other end of the first sliding rod passes through the first sliding groove and is limited by a nut. Under the drive of the driven member 152, the first sliding rod can move along the inside of the first sliding groove.

[0061] The support frame 155 is symmetrically provided with a third slide groove and a fourth slide groove. The support frame 155 and the other end of the two first mounting rods 158 are provided with a third sliding rod. The third sliding rod passes through one of the first mounting rods 158, the third slide groove and the other first mounting rod 158 in sequence. The two ends of the third sliding rod are fixedly connected to the two first mounting rods 158 respectively. The third sliding rod can move along the inside of the third slide groove.

[0062] The first test piece 156 includes a first mounting block and a first rolling element. The first mounting block has a first placement groove inside, and the first rolling element is disposed inside the first placement groove.

[0063] The first placement groove is a concave structure specifically designed to accommodate the first rolling element. The first placement groove matches the shape of the first rolling element and wraps around the first rolling element with an interference fit, thus restricting its radial and axial movement.

[0064] The specific procedure for adjusting the position of the first rolling element is as follows:

[0065] When the follower 152 rotates, it is slidably connected to the first groove of the first connecting rod 153 via the first sliding rod. The first groove limits the first sliding rod. Since the first connecting rod 153 is fixedly connected to the two first mounting rods 158, and the two first mounting rods 158 are slidably connected to the third groove of the support frame 155 via the third sliding rod, when the follower 152 moves the first connecting rod 153, the first connecting rod 153 then moves the two first mounting rods 158 along the third groove via the third sliding rod. Finally, under the restriction of the two first mounting rods 158 and the follower 152 on the first connecting rod 153, the first connecting rod 153 can move horizontally. Consequently, the first test piece 156 located at the bottom of the first connecting rod 153 can move horizontally along with the first connecting rod 153, thus enabling the first rolling element included in the first test piece 156 to move horizontally.

[0066] See Figures 8-10 Two second mounting rods 159 are provided corresponding to the two first mounting rods 158. The two second mounting rods 159 are slidably connected to the support frame 155. A second connecting rod 154 is provided at the end of the two second mounting rods 159. The second connecting rod 154 is fixedly connected to the two second mounting rods 159 respectively. The end of the second connecting rod 154 is slidably connected to the active member 151. A second test piece 157 is provided at the bottom of the second connecting rod 154.

[0067] The active member 151 extends to the side away from the toothed part and is provided with a second connecting part. The second connecting part and the active member 151 are integrally formed. A second sliding groove is provided on the second connecting rod 154. A second sliding rod is provided at the middle position of the second sliding groove on the second connecting part and the second connecting rod 154. One end of the second sliding rod is fixedly connected to the second connecting part, and the other end of the second sliding rod passes through the second sliding groove and is limited by a nut. Under the drive of the active member 151, the second sliding rod can move along the inside of the second sliding groove.

[0068] A fourth sliding rod is provided at the other end of the support frame 155 and the two second mounting rods 159. The fourth sliding rod passes through one of the second mounting rods 159, the fourth slide groove and the other second mounting rod 159 in sequence. The two ends of the fourth sliding rod are fixedly connected to the two second mounting rods 159 respectively. The fourth sliding rod can move along the inside of the fourth slide groove.

[0069] The second test piece 157 includes a second mounting block and a second rolling element. The second mounting block has a second placement groove inside, and the second rolling element is disposed inside the second placement groove. The connection relationship between the second placement groove and the second rolling element is consistent with the connection relationship between the first placement groove and the first rolling element.

[0070] The specific procedure for adjusting the position of the second rolling element is as follows:

[0071] When the active member 151 rotates under the drive of the drive motor 16, the active member 151 is slidably connected to the second sliding groove of the second connecting rod 154 through the second sliding rod. The second sliding groove limits the second sliding rod. Since the second connecting rod 154 is fixedly connected to the two second mounting rods 159, and the two second mounting rods 159 are slidably connected to the fourth sliding groove of the support frame 155 through the fourth sliding rod, when the active member 151 drives the second connecting rod 154 to move, the second connecting rod 154 then drives the two second mounting rods 159 to move along the fourth sliding groove through the fourth sliding rod. Finally, under the restriction of the two second mounting rods 159 and the active member 151 on the second connecting rod 154, the second connecting rod 154 can move in the horizontal direction. Consequently, the second test piece 157 set at the bottom of the second connecting rod 154 moves in the horizontal direction along with the second connecting rod 154, so that the second rolling element included in the second test piece 157 can move in the horizontal direction.

[0072] Since both the first and second rolling elements can move horizontally under the drive of the driven member 152 and the driving member 151 respectively, the first and second rolling elements can achieve horizontal clamping of the steel ring 3, laying the foundation for the normal conduct of subsequent testing.

[0073] The specific procedure for the testing agency 15 to limit the movement of steel ring 3 is as follows:

[0074] First, the drive motor 16 is started, which drives the driving member 151 to rotate. Due to the rotation of the driving member 151, the driven member 152 rotates along with it. At this time, as the driving member 151 rotates, the second connecting rod 154, being slidably connected to the driving member 151, moves along with it. Furthermore, because the second connecting rod 154 is fixedly connected to the two second mounting rods 159, the two second mounting rods 159 are slidably connected to the support frame 155, and the support frame 155 is fixed by the fixing plate, therefore, the second connecting rod 154... Driven by the action, the two second mounting rods 159 and the second test piece 157 move horizontally. Similarly, since the driven member 152 rotates following the driving member 151, the first connecting rod 153, the two first mounting rods 158 and the first test piece 156 can move horizontally under the action of the driven member 152. At this time, the first test piece 156 and the second test piece 157 move towards each other to achieve the limiting clamping of the steel ring 3, that is, the first rolling element and the second rolling element can be in close contact with the steel ring 3. The close contact between the steel ring 3 and the first rolling element and the second rolling element facilitates the normal conduct of subsequent testing.

[0075] Conversely, when the drive motor 16 is started in reverse, the first test piece 156 and the second test piece 157 move in opposite directions, and the first test piece 156 and the second test piece 157 release the steel ring 3.

[0076] The above structure enables the testing mechanism 15 to limit the steel ring 3. After the steel ring 3 is limited by the testing mechanism 15, the placement component 2 needs to be designed. The placement component 2 drives the steel ring 3 to rotate. After the steel ring 3 rotates, the steel ring 3 and the testing mechanism 15 will have relative motion, thereby realizing the test of the wear degree of the steel ring 3.

[0077] The specific structure of component 2 is as follows:

[0078] See Figure 2 and Figure 7 The placement component 2 includes an adjustment mechanism 21, which is located on the top of the workbench 11. A turntable mechanism 22 is located on the top of the adjustment mechanism 21, and a four-jaw chuck 23 is located on the top of the turntable mechanism 22. The four-jaw chuck 23 is used to clamp the steel ring 3.

[0079] The testing procedure for steel ring 3 is as follows:

[0080] First, the steel ring 3 to be tested is placed on the four-jaw chuck 23 by a robotic arm. The four-jaw chuck 23 is then activated to clamp the steel ring 3. Once the steel ring 3 is clamped stably, the first electric slide rail 13 and the second electric slide rail 14 are activated. The first electric slide rail 13 and the second electric slide rail 14 drive the testing mechanism 15 to adjust its position and move it to a position opposite to the steel ring 3. Next, the drive motor 16 is activated, which drives the first test piece 156 and the second test piece 157 to move towards each other. The first rolling element and the second rolling element are in contact with the steel ring 3. Then, the turntable mechanism 22 is activated, which drives the four-jaw chuck 23 to rotate. In turn, the four-jaw chuck 23 drives the steel ring 3 to rotate. After the steel ring 3 starts to rotate, the steel ring 3 moves relative to the first rolling element and the second rolling element, and the test of the steel ring 3 begins. This test method is called Test Method 1.

[0081] After the steel ring 3 test is completed, the movement of the turntable mechanism 22 is stopped, and the drive motor 16 is restarted to rotate in the opposite direction. The drive motor 16 drives the first test piece 156 and the second test piece 157 away from the steel ring 3. The four-jaw chuck 23 is restarted and releases the steel ring 3. The steel ring 3 is then transferred to the auxiliary testing device by the robot arm. The auxiliary testing device tests the wear condition of the steel ring 3 and outputs a test report.

[0082] The auxiliary testing device mainly uses a surface profilometer, which can measure the depth, width, and cross-sectional area of ​​wear marks on the surface of the steel ring 3. By quantifying the microscopic characteristics of local wear on the steel ring 3 using the above data, it is possible to distinguish different wear patterns such as wear marks and furrows, and output the relevant data in the form of a report. Operators can adjust the relevant production processes of the steel ring 3 based on the data report to improve the production quality of the steel ring 3.

[0083] The specific structure of the turntable mechanism 22 is as follows:

[0084] See Figure 6 The turntable mechanism 22 includes a power motor 221. The output end of the power motor 221 is connected to a transmission structure 222. The transmission structure 222 is located on the top of the worktable 11. A turntable body 223 is located above the transmission structure 222. The turntable body 223 is connected to the transmission structure 222 via a rotating shaft. A four-jaw chuck 23 is located on the top of the turntable body 223.

[0085] The transmission structure 222 consists of a reducer and a transmission shaft. The reducer can be a gearbox commonly used in the prior art. The transmission shaft is used to connect the power motor 221 and the reducer. The output end of the reducer is connected to the turntable body 223. When the power motor 221 is started, the power motor 221 drives the transmission structure 222 to rotate, and then the transmission structure 222 drives the turntable body 223 to rotate. After the turntable body 223 rotates, the turntable body 223 can drive the four-jaw chuck 23 to rotate, and the four-jaw chuck 23 then drives the steel ring 3 to rotate.

[0086] The above structure and corresponding operation can be used to perform conventional reciprocating wear tests on the steel ring 3. In practical applications, it is also necessary to conduct targeted tests on the actual working conditions of the steel ring 3. Therefore, by setting the specific structure of the adjustment mechanism 21, the position of the steel ring 3 can be adjusted by adjusting the adjustment mechanism 21, thereby changing the position of the steel ring 3 and testing the wear condition of the steel ring 3 under this working condition.

[0087] The specific structure of the regulating mechanism 21 is as follows:

[0088] See Figure 4 and Figure 5 The adjustment mechanism 21 includes three sets of bases 211, with a base plate 212 in the middle of the three sets of bases 211. Each set of bases 211 has a mounting seat 213 on its top, and each mounting seat 213 has an adjustment motor 214 on one side.

[0089] See Figure 4 and Figure 5 Each set of regulating motors 214 has a set of transmission rods 216 connected to its output end. Each set of transmission rods 216 has a set of connectors 218 on the side away from the regulating motors 214. Each set of connectors 218 is fixedly connected to each set of transmission rods 216. A top plate 219 is provided above the connectors 218. Each set of connectors 218 is rotatably connected to the top plate 219.

[0090] The adjusting motor 214, the transmission rod 216, and the connecting piece 218 constitute a set of angle adjusting components. When the adjusting motor 214 is started, the transmission rod 216 moves with the adjusting motor 214. Since the connecting piece 218 is fixedly connected to the transmission rod 216, the connecting piece 218 can swing under the drive of the transmission rod 216.

[0091] The adjustment mechanism 21 includes three sets of angle adjustment components, namely angle A, angle B, and angle C. The adjustment methods of the three sets of angle adjustment components are the same, and the tilting of the top plate 219 can be achieved by the cooperation of the three sets of angle adjustment components.

[0092] For example, when the top plate 219 tilts downwards and to the right, the tilting process of the top plate 219 is as follows:

[0093] First, adjust the A angle adjustment component to move to the upper right. At this time, the B angle adjustment component and the C angle adjustment component pull the top plate 219 to the lower right, ultimately tilting the top plate 219 to the lower right.

[0094] Similarly, the top plate 219 can be tilted at multiple angles by the cooperation of angle adjustment components A, B, and C.

[0095] When the top plate 219 tilts, the steel ring 3 located above the top plate 219 will tilt accordingly. At this time, the position of the steel ring 3 will change, but the horizontal position of the first rolling element in the first test piece 156 and the second rolling element in the second test piece 157 will not change and will remain in a horizontal position. The first rolling element and the second rolling element will be in a relatively tilted state relative to the steel ring 3. Then, the drive motor 16 is started to drive the first test piece 156 and the second test piece 157 to move towards each other. The first rolling element and the second rolling element will be in contact with the steel ring 3. Finally, the turntable mechanism 22 is started again, and the steel ring 3 is driven to rotate through the turntable mechanism 22. The steel ring 3 rotates relative to the first rolling element and the second rolling element, and the wear resistance test of the steel ring 3 begins. The method of testing the wear of the steel ring 3 under this working condition is test method two.

[0096] In actual testing, the same steel ring 3 can be tested using test method one first, and then tested using test method two to obtain the wear degree of the steel ring 3 under this continuous state. Alternatively, two sets of steel rings 3 can be selected to be tested using test method one and test method two respectively, and the wear degree of the steel ring 3 under the two states can be obtained. In actual data analysis, the test data can be compared to obtain more wear data, which helps to improve the production quality of the steel ring 3.

[0097] In Example 2, the steel ring 3 can be tested using the above structure through two testing methods. In Test Method 1, both the steel ring 3 and the testing mechanism 15 are placed horizontally, meaning that the contact points between the steel ring 3 and the first and second rolling elements are horizontal. In Test Method 2, the relative positions of the steel ring 3 and the first and second rolling elements change, meaning that the contact points between the first and second rolling elements and the steel ring 3 change. In addition, the steel ring 3 and the first and second rolling elements can also be in an inclined state simultaneously, meaning that the steel ring 3 and the first and second rolling elements move simultaneously. In this case, the contact points between the steel ring 3 and the first and second rolling elements do not change.

[0098] To achieve the above objectives, the connection between the testing mechanism 15 and the second electric slide rail 14 needs to be designed in detail to meet the requirements of position adjustment.

[0099] See Figure 3 A rotary cylinder 17 is provided on the side wall of the second electric slide rail 14. A mounting plate 18 is provided at the output end of the rotary cylinder 17. The mounting plate 18 is disc-shaped. A fixed seat 19 is provided on the side of the mounting plate 18 away from the rotary cylinder 17. A drive motor 16 is provided in the middle of the fixed seat 19. The output end of the drive motor 16 is connected to the test mechanism 15.

[0100] By setting a rotary cylinder 17 to connect the second electric slide rail 14 and the mounting plate 18, the rotary cylinder 17 is started, which can drive the mounting plate 18, drive motor 16, fixed base 19 and test mechanism 15 to rotate as a whole. In practical applications, the adjustment mechanism 21 is started to adjust the position of the steel ring 3. In order to make the position of the test mechanism 15 and the steel ring 3 adjusted synchronously, the rotary cylinder 17 is started to adjust the deflection amplitude of the test mechanism 15. In addition, the second electric slide rail 14 and the first electric slide rail 13 need to be started to adjust the horizontal and vertical positions of the test mechanism 15. Through the second electric slide rail 14, the first electric slide rail 13 and the rotary cylinder 17, the test mechanism 15 and the steel ring 3 are finally made to achieve synchronous deflection displacement.

[0101] For example, when the steel ring 3 needs to deflect downward to the right, firstly, the drive motor 16 is started, which drives the first test piece 156 and the second test piece 157 to release the steel ring 3. Then, the adjusting mechanism 21 is started, which drives the steel ring 3 to deflect downward to the right. After the steel ring 3 deflects, the rotary cylinder 17 is started, which drives the drive motor 16, the mounting plate 18, the fixed seat 19, and the testing mechanism 15 to deflect to the same side as the steel ring 3. After the testing mechanism 15 deflects, the first electric slide rail 13 is started, which horizontally drives the second electric slide rail 14 and the rotary cylinder 157. 7. The mounting plate 18, the fixed base 19, the drive motor 16, and the testing mechanism 15 are moved as a whole to the deflection position of the steel ring 3. Then, the second electric slide rail 14 is started. The second electric slide rail 14 drives the rotary cylinder 17, the mounting plate 18, the drive motor 16, and the testing mechanism 15 to move down as a whole. At this time, the position of the testing mechanism 15 and the steel ring 3 are aligned. Finally, the drive motor 16 is started again. The drive motor 16 drives the first test piece 156 and the second test piece 157 to move towards each other. The first rolling element and the second rolling element are in contact with the steel ring 3. Then, the four-jaw chuck 23 is started. The four-jaw chuck 23 drives the steel ring 3 to rotate, thereby realizing the wear test of the steel ring 3.

[0102] This test method is Test Method 3. In Test Method 3, the steel ring 3 can be adjusted in multiple directions, and the test mechanism 15 follows the steel ring 3 to achieve its multi-directional adjustment.

[0103] See Figures 11-13 Based on the above structure, three testing methods for steel ring 3 can be realized through the testing device, namely testing method one, testing method two and testing method three.

[0104] In actual testing, the steel rings 3 to be tested can be divided into several groups, and each group of steel rings 3 can be marked. The marked steel rings 3 can be put into different test procedures. According to the test method, the test procedure can be decomposed into multiple groups. Test method 1, test method 2 and test method 3 are tested independently as procedure 1. Test method 1 and test method 2 are combined as procedure 2. Test method 1 and test method 3 are combined as procedure 3. Test method 2 and test method 3 are combined as procedure 4. Test method 1, test method 2 and test method 3 are tested in sequence as procedure 5. The above five procedures are the basic test procedures. In actual testing, the order of the test methods can be changed to obtain different test data.

[0105] Different test data reports can be obtained by different test procedures, which can comprehensively test the wear resistance of steel ring 3. At the same time, the corresponding production process can be improved based on the differences in the test data reports, thereby improving the production quality of steel ring 3 and thus increasing its service life.

[0106] Example 3: A testing method for a wear-resistant steel ring wear resistance testing device, using the above-mentioned wear-resistant steel ring wear resistance testing device, including the following steps:

[0107] In this embodiment three, the test is conducted in the order of test method one, test method two, and test method three in embodiment two. That is, the wear resistance of steel ring 3 is tested through test method five. For the other test methods, the technicians can implement them according to the actual test content.

[0108] The test steps for test process five are as follows:

[0109] S1. First, the steel ring 3 is placed on top of the placement component 2 by the robotic arm, and the placement component 2 clamps the steel ring 3.

[0110] S11. The steel ring 3 to be tested is placed on the position of the four-jaw chuck 23 by the robotic arm, and the four-jaw chuck 23 is activated to clamp the steel ring 3.

[0111] S2. Next, after the steel ring 3 is clamped, adjust the position of the test component 1 to match the steel ring 3, and at the same time start the placement component 2. The placement component 2 drives the steel ring 3 to rotate relative to the test component 1 to conduct a preliminary wear resistance test.

[0112] S21. After the steel ring 3 is clamped and stabilized, the first electric slide rail 13 and the second electric slide rail 14 are activated. The first electric slide rail 13 and the second electric slide rail 14 drive the test mechanism 15 to adjust its position and move to the position opposite to the steel ring 3.

[0113] S22. Restart the drive motor 16. The drive motor 16 drives the first test piece 156 and the second test piece 157 to move towards each other. The first rolling element and the second rolling element are in contact with the steel ring 3.

[0114] S23. Start the turntable mechanism 22 again. The turntable mechanism 22 drives the four-jaw chuck 23 to rotate, and then the four-jaw chuck 23 drives the steel ring 3 to rotate.

[0115] S24. After the steel ring 3 starts to rotate, the steel ring 3 moves relative to the first rolling element and the second rolling element, that is, the preliminary wear resistance test of the steel ring 3 by test method one begins.

[0116] S3. Then, after the preliminary wear resistance test is completed, the position of the steel ring 3 is adjusted by placing component 2. After the position of the steel ring 3 changes, the position of test component 1 is adjusted again to match the steel ring 3. After the positions of test component 1 and steel ring 3 are adjusted, the placing component 2 is started to drive the steel ring 3 to rotate relative to test component 1, and the wear resistance test of the steel ring 3 under different working conditions is carried out again.

[0117] S31. After the initial wear resistance test of the steel ring 3 is completed, stop the movement of the turntable mechanism 22, and start the drive motor 16 to rotate in the opposite direction. The drive motor 16 drives the first test piece 156 and the second test piece 157 away from the steel ring 3.

[0118] S32. Then, start the adjustment motors 214 corresponding to the angle adjustment components A, B, and C respectively. Under the combined action of the respective adjustment motors 214, the top plate 219 will tilt. After the top plate 219 tilts, the steel ring 3 set above the top plate 219 will tilt accordingly, and the position of the steel ring 3 will change.

[0119] S33. Start the drive motor 16 to drive the first test piece 156 and the second test piece 157 to move towards each other. The first rolling element and the second rolling element are in contact with the steel ring 3. Start the turntable mechanism 22 again. The turntable mechanism 22 drives the steel ring 3 to rotate. The steel ring 3 rotates relative to the first rolling element and the second rolling element. The steel ring 3 begins the wear resistance test of method two.

[0120] S34. After the wear resistance test of test method two is completed, the test mechanism 15 releases the steel ring 3 and starts the adjustment mechanism 21 to adjust the position of the steel ring 3. In order to synchronize the position adjustment of the test mechanism 15 and the steel ring 3, the rotary cylinder 17 is started. The deflection amplitude of the test mechanism 15 is adjusted by the rotary cylinder 17. Then the second electric slide rail 14 and the first electric slide rail 13 are started to adjust the horizontal and vertical positions of the test mechanism 15, so that the test mechanism 15 and the steel ring 3 achieve synchronous deflection displacement.

[0121] S35. Finally, start the drive motor 16 again. The drive motor 16 drives the first test piece 156 and the second test piece 157 to move towards each other. The first rolling element and the second rolling element are in contact with the steel ring 3. Start the four-jaw chuck 23 again. The four-jaw chuck 23 drives the steel ring 3 to rotate, realizing the wear resistance test of the steel ring 3 by test method three.

[0122] S36. After Test Method 1, Test Method 2, and Test Method 3 are completed in sequence, the steel ring 3 is transferred to the station of the auxiliary testing device by the robot arm. The wear condition of the steel ring 3 is tested by the auxiliary testing device, and a test report is output.

[0123] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
