Description

Technical Field

[0001] The present invention relates to the technical field of wear-resistant steel ring wear-resistance testing, and more particularly to a wear-resistant steel ring wear-resistance performance testing device and a testing method. Background Art

[0002] Wear-resistant steel rings are annular components made mainly of high-strength wear-resistant steel. Due to their excellent wear resistance, wear-resistant steel rings are widely used in a variety of industrial equipment and machinery. As core components, they are embedded in various bearings to reduce friction loss and ensure rotation accuracy.

[0003] Currently, in bearings, when wear-resistant steel rings are used as inner rings, the steel rings are mainly subject to wear caused by the rolling elements in direct contact with them. During high-speed rotation, the rolling elements form continuous rolling friction with the inner ring raceway, which can easily cause surface fatigue wear. Therefore, in the actual production process, after a batch of steel rings is produced, they need to be sampled and tested to test whether their wear resistance meets the production standards.

[0004] The existing test of the wear resistance of steel rings is to simulate contact wear through sliding friction between the specimen and the rotating disk, and then measure the wear amount through a surface profilometer and output a data test report.

[0005] However, the existing testing device mainly tests the wear resistance of the steel ring through reciprocating motion under the same working conditions. During the test, the placement state of the steel ring is not changed, and there is a lack of a process for testing the wear resistance of the steel ring under different working conditions. The test results lack comprehensiveness, and the test results are not sufficient for reference in process production.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] 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 ordinary technicians in the technical field to which this application belongs.

[0038] See also Figures 1-13 , the present invention provides the following technical solutions: Example 1, see Figure 1 In order to solve the problem that the test results in existing tests lack comprehensiveness and are not sufficient reference for process production, a wear-resistant steel ring wear resistance testing device is proposed to solve the related problems. The wear resistance testing device includes a test component 1, a placement component 2 is arranged above the test component 1, and a steel ring 3 is arranged in the middle position of the placement component 2.

[0039] Among them, the steel ring 3 can be tested through the test component 1, and the steel ring 3 can be clamped through the placement component 2. In actual application, the produced steel ring 3 is first sampled, and then the reciprocating wear resistance test of the steel ring 3 can be achieved through the cooperation of the test component 1 and the placement component 2.

[0040] The specific structure of test component 1 is as follows: See Figure 2 and Figure 3 The test assembly 1 includes a workbench 11, a bracket 12 is provided on the top of the workbench 11, a first electric slide 13 is provided on one side of the bracket 12, a second electric slide 14 is provided on the side of the first electric slide 13 away from the bracket 12, and a testing mechanism 15 is provided on the side of the second electric slide 14 away from the first electric slide 13.

[0041] See Figure 2 and Figure 3 A mounting plate 18 is provided on one side of the second electric slide rail 14 , a fixing seat 19 is provided on the side of the mounting plate 18 away from the second electric slide rail 14 , a driving motor 16 is provided in the middle position of the fixing seat 19 , and the output end of the driving motor 16 is connected to the testing mechanism 15 .

[0042] In actual application, start the first electric slide 13, and the first electric slide 13 drives the second electric slide 14, the mounting plate 18, the drive motor 16, the fixed seat 19 and the testing mechanism 15 to move in the horizontal direction. Start the second electric slide 14, and the second electric slide 14 can drive the mounting plate 18, the drive motor 16, the fixed seat 19 and the testing mechanism 15 to move in the vertical direction. The position of the testing mechanism 15 can be adjusted through the horizontal and vertical movements, which facilitates the normal testing of the steel ring 3 by the subsequent testing mechanism 15.

[0043] During the actual test process, the test mechanism 15 needs to simulate the actual working conditions. Therefore, in actual application, the specific structure of the test mechanism 15 needs to be designed. The specific structure of the test mechanism 15 is as follows: See Figures 8-10 The testing mechanism 15 includes a first testing piece 156 and a second testing piece 157 arranged opposite to the first testing piece 156 .

[0044] See Figures 8-10 The testing mechanism 15 also includes an active member 151, which is connected to the output end of the driving motor 16. A driven member 152 is provided on one side of the active member 151, and the driven member 152 is engaged with the active member 151. A support frame 155 is provided on the same side of the driven member 152 and the active member 151.

[0045] The follower 152 is hinged to the support frame 155, and the support frame 155 is set to a special-shaped structure. A fixing plate is set in 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.

[0046] Among them, the active member 151 and the driven member 152 are incomplete gear structures, wherein the toothed side of the active member 151 and the driven member 152 is meshingly configured. When the drive motor 16 is started, the drive motor 16 drives the active member 151 to rotate, and then the active member 151 drives the driven member 152 to follow its movement.

[0047] The follower 152 and the support frame 155 are connected via a fixing rod, so that the follower 152 and the support frame 155 are kept in a hinged state.

[0048] In addition, by providing a fixing plate to connect the support frame 155 and the mounting plate 18, the position of the support frame 155 can be limited, and the clamping work of the test mechanism 15 can be operated normally.

[0049] See Figures 8-10A first mounting rod 158 is provided on both sides of the support frame 155, and the two first mounting rods 158 are slidably connected to the support frame 155. A first connecting rod 153 is provided at the end position of the two first mounting rods 158. The first connecting rod 153 is fixedly connected to the two first mounting rods 158 respectively, and the end of the first connecting rod 153 is slidably connected to the follower 152. A first test piece 156 is provided at the bottom of the first connecting rod 153.

[0050] Among them, the follower 152 is extended with a first connecting part away from the toothed side, the first connecting part and the follower 152 are integrally formed, a first sliding groove is provided on the first connecting rod 153, and a first sliding rod is provided in the middle position between 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. Driven by the follower 152, the first sliding rod can move along the inside of the first sliding groove.

[0051] A third slide groove and a fourth slide groove are symmetrically provided on the support frame 155. A third sliding rod is provided at the other end of the support frame 155 and the two first mounting rods 158. 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, and the third sliding rod can move inside the third slide groove.

[0052] The first test piece 156 includes a first mounting block and a first rolling body. A first placement groove is provided inside the first mounting block, and the first rolling body is provided inside the first placement groove.

[0053] Among them, the first placement groove is a concave structure specifically for accommodating the first rolling body. The first placement groove matches the shape of the first rolling body. The first placement groove wraps the first rolling body through interference fit to limit its radial and axial movement.

[0054] The specific process of adjusting the position of the first rolling element is as follows: When the follower 152 rotates, since the follower 152 is slidably connected to the first sliding groove of the first connecting rod 153 through the first sliding rod, the first sliding groove will limit the first sliding rod. Moreover, because 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 sliding groove of the support frame 155 through the third sliding rod, when the follower 152 drives the first connecting rod 153 to move, the first connecting rod 153 drives the two first mounting rods 158 to move along the third sliding groove through 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 in the horizontal direction, and then the first test piece 156 arranged at the bottom of the first connecting rod 153 can follow the first connecting rod 153 to move in the horizontal direction, so that the first rolling body included in the first test piece 156 moves in the horizontal direction.

[0055] See Figures 8-10 Two second mounting rods 159 are respectively arranged corresponding to the two first mounting rods 158. The two second mounting rods 159 are slidably connected to the support frame 155. Second connecting rods 154 are provided at the end positions 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 part 151, and a second test piece 157 is provided at the bottom of the second connecting rod 154.

[0056] A second connecting portion is extended from the side of the active member 151 away from the teeth. The second connecting portion 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 in the middle position between the second connecting portion and the second sliding groove on the second connecting rod 154. One end of the second sliding rod is fixedly connected to the second connecting portion, and the other end of the second sliding rod passes through the second sliding groove and is limited by a nut. Driven by the active member 151, the second sliding rod can move along the inside of the second sliding groove.

[0057] A fourth sliding rod is provided at the other end position 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 sliding 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, and the fourth sliding rod can move along the inside of the fourth sliding groove.

[0058] The second test piece 157 includes a second mounting block and a second rolling body. A second placement groove is provided inside the second mounting block. The second rolling body is provided inside the second placement groove. The connection relationship between the second placement groove and the second rolling body is consistent with the connection relationship between the first placement groove and the first rolling body.

[0059] The specific process of adjusting the position of the second rolling element is as follows: When the active member 151 rotates under the drive motor 16, since 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 will limit the second sliding rod. In addition, because 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, therefore, when the active member 151 drives the second connecting rod 154 to move, the second connecting rod 154 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, and then the second test member 157 arranged at the bottom of the second connecting rod 154 follows the second connecting rod 154 to move in the horizontal direction, so that the second rolling body included in the second test member 157 can move in the horizontal direction.

[0060] Based on the above-mentioned fact that the first rolling body and the second rolling body can both move horizontally driven by the follower 152 and the active member 151 respectively, the first rolling body and the second rolling body can achieve horizontal clamping of the steel ring 3, laying the foundation for the normal progress of subsequent testing work.

[0061] The specific process of the testing mechanism 15 limiting the steel ring 3 is as follows: First, the driving motor 16 is started, and the driving motor 16 drives the active member 151 to rotate. Due to the rotation of the active member 151, the driven member 152 rotates following the active member 151. At this time, when the active member 151 rotates, since the second connecting rod 154 and the active member 151 are in a sliding connection, the second connecting rod 154 moves following the active member 151. Moreover, since 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, Driven by the second mounting rods 159, the two second mounting rods 159 and the second test piece 157 move horizontally. Similarly, since the follower 152 rotates following the active piece 151, driven by the follower 152, the first connecting rod 153, the two first mounting rods 158 and the first test piece 156 can achieve horizontal movement. At this time, the first test piece 156 and the second test piece 157 move toward each other to achieve limited clamping of the steel ring 3, that is, the first rolling body and the second rolling body can be in close contact with the steel ring 3. The close contact between the steel ring 3 and the first rolling body and the second rolling body facilitates the normal progress of subsequent testing work.

[0062] On the contrary, when the driving motor 16 is started in the reverse direction, the first test piece 156 and the second test piece 157 move in the reverse direction, and the first test piece 156 and the second test piece 157 release the steel ring 3.

[0063] The above structure can realize the limitation of the steel ring 3 by the testing mechanism 15. After the steel ring 3 is limited by the testing mechanism 15, the placement component 2 needs to be designed to drive the steel ring 3 to rotate through the placement component 2. After the steel ring 3 rotates, the steel ring 3 and the testing mechanism 15 generate relative motion, thereby realizing the test of the wear of the steel ring 3.

[0064] The specific structure of placement component 2 is as follows: See Figure 2 and Figure 7 The placement component 2 includes an adjusting mechanism 21, which is arranged on the top of the workbench 11. A turntable mechanism 22 is provided on the top of the adjusting mechanism 21, and a four-claw chuck 23 is provided on the top of the turntable mechanism 22. The four-claw chuck 23 is used to clamp the steel ring 3.

[0065] The test process for steel ring 3 is as follows: First, the steel ring 3 to be tested is placed in the position of the four-claw chuck 23 by the manipulator, and the four-claw chuck 23 is started to clamp the steel ring 3. When the steel ring 3 is clamped stably, the first electric slide 13 and the second electric slide 14 are started. The first electric slide 13 and the second electric slide 14 drive the testing mechanism 15 to adjust its position and move it to a position opposite to the steel ring 3. Secondly, 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 toward each other, and the first rolling body and the second rolling body are in contact with the steel ring 3. Then the turntable mechanism 22 is started again. The turntable mechanism 22 drives the four-claw chuck 23 to rotate, and then the four-claw chuck 23 drives the steel ring 3 to rotate. After the steel ring 3 starts to rotate, the steel ring 3 and the first rolling body and the second rolling body move relative to each other, that is, the steel ring 3 starts to be tested. This test method is test method one.

[0066] After the test of the steel ring 3 is completed, the movement of the turntable mechanism 22 is stopped, and the drive motor 16 is started again 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, and the four-claw chuck 23 is started again. The four-claw chuck 23 releases the steel ring 3, and the steel ring 3 is transferred to the auxiliary testing device by the manipulator. The wear condition of the steel ring 3 is tested by the auxiliary testing device, and a test report is output.

[0067] The auxiliary testing device mainly uses a surface profilometer, which can measure the depth, width, and cross-sectional area of ​​the wear marks on the surface of the steel ring 3. The above data can quantify the microscopic characteristics of the local wear of the steel ring 3, distinguish different wear forms such as wear marks and furrows, and output the relevant data content in the form of a report. The operator adjusts the relevant production process of the steel ring 3 according to the data report to improve the production quality of the steel ring 3.

[0068] The specific structure of the turntable mechanism 22 is as follows: 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 arranged on the top of the workbench 11, and a turntable body 223 is arranged above the transmission structure 222. The turntable body 223 is connected to the transmission structure 222 through a rotating shaft, and a four-claw chuck 23 is arranged on the top of the turntable body 223.

[0069] The transmission structure 222 consists of a reducer and a transmission shaft. The reducer can be a reduction box 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. Start the power motor 221, and 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-claw chuck 23 to rotate, and the four-claw chuck 23 then drives the steel ring 3 to rotate.

[0070] The above structure and corresponding operation can realize the conventional reciprocating wear test of the steel ring 3. In practical applications, it is also necessary to carry out targeted testing on the actual working conditions of the steel ring 3. Therefore, by setting the specific structure of the adjustment mechanism 21 and adjusting the adjustment mechanism 21, the adjustment mechanism 21 adjusts the position of the steel ring 3 to realize the change of the position of the steel ring 3 and test the wear of the steel ring 3 under this working condition.

[0071] The specific structure of the regulating mechanism 21 is as follows: See Figure 4 and Figure 5 The adjustment mechanism 21 includes three groups of bases 211, a bottom plate 212 is provided in the middle position of the three groups of bases 211, a group of mounting seats 213 are respectively provided on the top of the three groups of bases 211, and a group of adjustment motors 214 are respectively provided on one side of each group of mounting seats 213.

[0072] See Figure 4 and Figure 5 The output end of each group of adjusting motors 214 is connected to a group of transmission rods 216, and each group of transmission rods 216 is provided with a group of connecting parts 218 on the side away from the adjusting motor 214. Each group of connecting parts 218 is fixedly connected to each group of transmission rods 216, and a top plate 219 is provided above the connecting parts 218. Each group of connecting parts 218 is rotatably connected to the top plate 219.

[0073] Among them, the adjusting motor 214, the transmission rod 216, and the connecting member 218 constitute a group of angle adjustment components. When the adjusting motor 214 is started, the transmission rod 216 moves following the adjusting motor 214 under the drive of the adjusting motor 214. Since the connecting member 218 is fixedly connected to the transmission rod 216, the connecting member 218 can swing under the drive of the transmission rod 216.

[0074] The adjustment mechanism 21 includes three groups of angle adjustment components, namely angle adjustment component A, angle adjustment component B, and angle adjustment component C. The adjustment methods of the three groups of angle adjustment components are consistent. According to the mutual cooperation of the three groups of angle adjustment components, the position of the top plate 219 can be tilted.

[0075] For example, when the top plate 219 tilts downward to the right, the tilting process of the top plate 219 is as follows: First, adjust the angle adjustment component A to move to the upper right. At this time, the angle adjustment components B and C pull the top plate 219 to the lower right, and finally the top plate 219 is tilted to the lower right.

[0076] Similarly, the top plate 219 can be tilted at multiple angles according to the cooperation among the angle adjustment component A, the angle adjustment component B and the angle adjustment component C.

[0077] When the top plate 219 is tilted, the steel ring 3 arranged above the top plate 219 will tilt along with it. At this time, the position of the steel ring 3 will change, but the horizontal positions of the first rolling body in the first test piece 156 and the second rolling body in the second test piece 157 have not changed, and are still in a horizontal placement state. The first rolling body and the second rolling body are 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 toward each other, and the first rolling body and the second rolling body fit the steel ring 3. Finally, the turntable mechanism 22 is started again, and the steel ring 3 is driven to rotate by the turntable mechanism 22. The steel ring 3 rotates relative to the first rolling body and the second rolling body, and the steel ring 3 starts the wear resistance test. The method of testing the wear degree of the steel ring 3 under this working condition is test method two.

[0078] In actual testing, the same steel ring 3 can be tested using test method one first and then using test method two to obtain the degree of wear of the steel ring 3 under this continuous state. Alternatively, two groups of steel rings 3 can be selected to perform tests using test method one and test method two respectively, and the degree of wear of the steel ring 3 under the two states can be obtained. In actual data analysis, the test data can be compared to provide more abundant wear data, which helps to improve the production quality of the steel ring 3.

[0079] Example 2: The steel ring 3 can be tested by two testing methods through the above structure. In the test method 1, the steel ring 3 and the test mechanism 15 are both in a horizontal position, that is, the contact points of the steel ring 3 with the first rolling body and the second rolling body are both at horizontal contact points; in the test method 2, the relative positions of the steel ring 3 and the first rolling body and the second rolling body have changed, that is, the contact points of the first rolling body and the second rolling body with the steel ring 3 have changed; in addition, the steel ring 3 and the first rolling body and the second rolling body can also be in an inclined state at the same time, that is, the steel ring 3 and the first rolling body and the second rolling body move in position at the same time. At this time, the contact points of the steel ring 3 with the first rolling body and the second rolling body have not changed.

[0080] In order to achieve the above purpose, it is necessary to carry out detailed design of the connection relationship between the testing mechanism 15 and the second electric slide rail 14 so as to meet the requirements of position adjustment.

[0081] See Figure 3 A rotating cylinder 17 is provided on the side wall of the second electric slide rail 14, and a mounting plate 18 is provided at the output end of the rotating cylinder 17. The mounting plate 18 is set in a disc shape, and a fixing seat 19 is provided on the side of the mounting plate 18 away from the rotating cylinder 17. A driving motor 16 is provided in the middle position of the fixing seat 19, and the output end of the driving motor 16 is connected to the testing mechanism 15.

[0082] By setting a rotating cylinder 17 to connect the second electric slide 14 and the mounting plate 18, the rotating cylinder 17 is started. The rotating cylinder 17 can drive the mounting plate 18, the drive motor 16, the fixing seat 19 and the testing mechanism 15 to rotate as a whole. In actual application, the adjusting mechanism 21 is started to adjust the position of the steel ring 3. In order to adjust the position of the testing mechanism 15 and the steel ring 3 synchronously, the rotating cylinder 17 is started. The deflection amplitude of the testing mechanism 15 is adjusted by the rotating cylinder 17. In addition, it is also necessary to start the second electric slide 14 and the first electric slide 13 to adjust the horizontal and vertical positions of the testing mechanism 15. The second electric slide 14, the first electric slide 13 and the rotating cylinder 17 are used to finally achieve synchronous deflection displacement of the testing mechanism 15 and the steel ring 3.

[0083] For example, when the steel ring 3 needs to be deflected to the lower right, first, the drive motor 16 is started, and the first test piece 156 and the second test piece 157 are driven by the drive motor 16 to release the steel ring 3, and then the adjustment mechanism 21 is started, and the adjustment mechanism 21 drives the steel ring 3 to realize the deflection to the lower right. After the deflection of the steel ring 3 is completed, the rotating cylinder 17 is started, and the rotating cylinder 17 drives the drive motor 16, the mounting plate 18, the fixing seat 19 and the test mechanism 15 to deflect to the same side as the deflection of the steel ring 3. After the deflection of the test mechanism 15 is completed, the first electric slide 13 is started, and the first electric slide 13 drives the second electric slide 14 and the rotating cylinder 15 horizontally. 7. The mounting plate 18, the fixing seat 19, the drive motor 16 and the test mechanism 15 are moved as a whole to the deflection position of the steel ring 3, and then the second electric slide rail 14 is started. The second electric slide rail 14 drives the rotating cylinder 17, the mounting plate 18, the drive motor 16 and the test mechanism 15 to move downward as a whole. At this time, the position movement of the test mechanism 15 is consistent with that of the steel ring 3. 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 toward each other. The first rolling body and the second rolling body fit 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.

[0084] This testing method is test method three. In test method three, the steel ring 3 can be adjusted in multiple directions, and the testing mechanism 15 follows the steel ring 3 to achieve its multi-directional adjustment.

[0085] See Figure 11-13 According to the above structure, three steel ring 3 testing methods can be implemented through the testing device, namely test method one, test method two and test method three.

[0086] During the actual testing process, the steel rings 3 to be tested can be divided into several groups, and several groups of steel rings 3 can be marked respectively, and the marked steel rings 3 can be put into different testing processes respectively. The testing process can be decomposed into multiple groups according to the testing method. Test method one, test method two and test method three are tested independently as process one, test method one and test method two are combined as process two, test method one and test method three are combined as process three, test method two and test method three are combined as process four, and test method one, test method two and test method three are tested in sequence as process five. The above five processes are basic testing processes. During the actual testing process, the order of the test methods can also be changed to obtain different test data.

[0087] Different test data reports can be obtained according to different test processes, and the wear resistance of the steel ring 3 can be tested in all directions. At the same time, according to the data differences in the test data reports, the corresponding production process can be improved, the production quality of the steel ring 3 can be improved, and the service life of the steel ring 3 can be increased.

[0088] Example 3, a method for testing the wear resistance performance of a wear-resistant steel ring using the wear resistance performance testing device, comprising the following steps: This embodiment three is tested in the order of test method one, test method two, and test method three in embodiment two, that is, the wear resistance of the steel ring 3 is tested through test process five. The remaining test processes can be implemented by technicians according to the actual test content.

[0089] Among them, the test steps of test process five are as follows: S1. First, the steel ring 3 is placed on top of the placement component 2 by a robot, and the placement component 2 clamps the steel ring 3.

[0090] S11. Place the steel ring 3 to be tested on the position of the four-claw chuck 23 by a manipulator, and start the four-claw chuck 23 to clamp the steel ring 3.

[0091] S2. Secondly, after the steel ring 3 is clamped, the position of the test component 1 is adjusted to match the steel ring 3, and the placement component 2 is started at the same time. The placement component 2 drives the steel ring 3 to rotate relative to the test component 1 to perform a preliminary wear resistance test.

[0092] S21. After the steel ring 3 is clamped stably, the first electric slide rail 13 and the second electric slide rail 14 are started. The first electric slide rail 13 and the second electric slide rail 14 drive the testing mechanism 15 to adjust its position and move to a position opposite to the steel ring 3.

[0093] S22 , restart the driving motor 16 , and the driving motor 16 drives the first test piece 156 and the second test piece 157 to move toward each other, and the first rolling body and the second rolling body fit with the steel ring 3 .

[0094] S23, restart the turntable mechanism 22, the turntable mechanism 22 drives the four-claw chuck 23 to rotate, and then the four-claw chuck 23 drives the steel ring 3 to rotate.

[0095] S24, after the steel ring 3 starts to rotate, the steel ring 3 and the first rolling body and the second rolling body move relative to each other, that is, the preliminary wear resistance test of the test method 1 is started on the steel ring 3.

[0096] S3. Then, after the preliminary wear resistance test is completed, the position of the steel ring 3 is adjusted by placing the component 2. When the position of the steel ring 3 changes, the position of the test component 1 is adjusted again to match the steel ring 3. After the position adjustment of the test component 1 and the steel ring 3 is completed, the placement component 2 is started to drive the steel ring 3 to rotate relative to the test component 1, and the wear resistance test of the steel ring 3 under different working conditions is performed again.

[0097] S31. After the preliminary wear resistance test of the steel ring 3 is completed, the movement of the turntable mechanism 22 is stopped, and the drive motor 16 is started again to rotate in the reverse direction. The drive motor 16 drives the first test piece 156 and the second test piece 157 away from the steel ring 3.

[0098] S32. Start the adjustment motors 214 corresponding to the angle adjustment component A, the angle adjustment component B, and the angle adjustment component C respectively. With the cooperation of the respective adjustment motors 214, the top plate 219 will tilt. After the top plate 219 tilts, the steel ring 3 arranged above the top plate 219 will tilt along with it, and the position of the steel ring 3 will change at this time.

[0099] S33, start the driving motor 16 to drive the first test piece 156 and the second test piece 157 to move toward each other, and the first rolling body and the second rolling body are in contact with the steel ring 3, and start the turntable mechanism 22 again, and the steel ring 3 is driven to rotate by the turntable mechanism 22, and the steel ring 3 rotates relative to the first rolling body and the second rolling body, and the steel ring 3 starts the wear resistance test of the second test method.

[0100] S34. After the wear resistance test of test method 2 is completed, the test mechanism 15 releases the steel ring 3, and the adjustment mechanism 21 is started to adjust the position of the steel ring 3. In order to synchronize the position of the test mechanism 15 and the steel ring 3, the rotating cylinder 17 is started, and the deflection amplitude of the test mechanism 15 is adjusted by the rotating 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, and finally the test mechanism 15 and the steel ring 3 achieve synchronous deflection displacement.

[0101] 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 toward each other. The first rolling body and the second rolling body fit the steel ring 3. Start the four-jaw chuck 23 again. The four-jaw chuck 23 drives the steel ring 3 to rotate, thereby realizing the wear resistance test of the steel ring 3 according to the third test method.

[0102] S36. After test method 1, test method 2 and test method 3 are completed in sequence, the steel ring 3 is moved to the workstation of the auxiliary test device by the robot again, the wear condition of the steel ring 3 is tested by the auxiliary test device, and a test report is output.

[0103] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
