Description

Technical Field

[0001] This utility model relates to the technical field of wear resistance testing instruments, specifically an intelligent material surface wear resistance testing instrument. Background Technology

[0002] Material surface abrasion resistance testing is a crucial method for evaluating a material's ability to resist wear under friction. During testing, a specialized abrasion testing machine is typically used to simulate friction conditions in actual use, such as setting specific parameters like load, rotational speed, and materials used in the friction pair. A standard specimen of the material to be tested is prepared and subjected to relative motion with the friction pair. The abrasion resistance of the material is quantified by measuring indicators such as mass loss, dimensional changes, or surface morphology alterations before and after wear. This testing is essential for fields such as machinery manufacturing, automotive, and aerospace, helping engineers select materials with superior abrasion resistance, improve product lifespan and reliability, and reduce failures and maintenance costs caused by wear.

[0003] Utility model patent CN221100385U discloses a device for testing the abrasion resistance of waterproof materials. It includes a base with a vertical plate on the base. A motor is mounted on one side of the vertical plate, and a turntable is mounted on the other side. The motor is connected to the turntable. A rotating shaft is located on one side of the turntable. The device also includes a friction block with vertically oriented friction holes and a lower friction material layer. The rotating shaft is inserted into the friction block holes. A clamp for holding the waterproof material is also located on the base. In use, the clamp holds the waterproof material. When the turntable rotates and the rotating shaft approaches the lower surface, the friction material layer contacts the upper surface of the waterproof material and advances through friction. This device for testing the abrasion resistance of waterproof materials has the advantages of simple structure and ease of use.

[0004] While the aforementioned device can test the wear resistance of material surfaces, the impact force applied to the material surface at the moment the friction block rotates and falls and makes contact with the material is much greater than the subsequent downward pressure applied by the friction block due to its own weight. This causes a drastic change in the friction between the friction block and the material at this moment, making it impossible to ensure the stability of the friction applied during the test. Furthermore, the impact may cause deformation of the material surface, affecting normal testing. In addition, since the friction is affected by the downward pressure, and the downward pressure applied to the material by the friction block is mostly its own gravity load, it is impossible to freely adjust the downward pressure applied to the material surface by the testing equipment during the test. Consequently, it is difficult to meet different testing needs, resulting in a relatively limited application scenario. Therefore, to address the above problems, an intelligent material surface wear resistance tester is proposed. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide an intelligent material surface abrasion resistance tester. During use, the tester uses a hydraulic cylinder to drive a transmission frame downwards, causing the force-measuring pressure frame mounted on it to move downwards, bringing the friction roller assembly into contact with the surface of the material to be tested. During the test, the friction roller assembly rotates at high speed, rubbing against the material surface, while the material is simultaneously conveyed forward by a feeding platform. Throughout this process, because the friction roller assembly remains in constant contact with the material surface and the applied downward pressure is almost constant, the stability of the applied friction during the test is ensured, and no impact is caused to the material surface, preventing deformation. Furthermore... The spring force measuring mechanism inside the force measuring and pressing frame can transmit the downward pressure of the hydraulic cylinder and monitor the downward pressure applied to the friction roller assembly in real time. When simulating different test conditions, the magnitude of the force transmitted by the spring force measuring mechanism can be adjusted by controlling the stroke of the hydraulic cylinder, thereby measuring the wear resistance of the material surface under different downward pressure conditions. This solves the technical problems in comparative technologies, such as the difficulty in ensuring the stability of friction during testing, the possibility that impact may cause deformation of the material surface and affect normal testing, and the inability to freely adjust the downward pressure applied to the material surface by the testing equipment during testing, making it difficult to meet different testing needs.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] An intelligent material surface abrasion resistance tester includes a feeding platform with a supporting gantry mounted on it, a transmission frame slidably mounted on the supporting gantry, a hydraulic cylinder mounted on the supporting gantry for driving the transmission frame to move up and down, a force-measuring pressure frame mounted below the transmission frame, a friction roller assembly mounted below the force-measuring pressure frame, and a rotation drive mechanism for driving the friction roller assembly to rotate. The force-measuring pressure frame includes a connecting plate, which is slidably connected to the transmission frame via a sliding rod connected thereto. A spring force-measuring mechanism is provided outside the sliding rod to monitor the downward pressure applied by the transmission frame to the connecting plate. Based on this design, during the testing process, since the friction roller assembly is always in contact with the material surface and the applied downward pressure remains almost constant, the stability of the applied friction during the test can be ensured, and the material surface will not be impacted, causing deformation. Furthermore, when simulating different test conditions, the magnitude of the force transmitted by the spring force-measuring mechanism can be adjusted by controlling the stroke of the hydraulic cylinder, thereby measuring the abrasion resistance of the material surface under different downward pressure conditions.

[0008] In one possible implementation, the spring force measuring mechanism includes an annular pressure sensor mounted on a connecting plate, on which a pressure ring is slidably sleeved on a sliding rod. A force-transmitting spring is mounted on the pressure ring, with its two ends abutting against the pressure ring and the transmission frame, respectively. In addition, an anti-detachment end is fixedly connected to the top of the sliding rod. When the friction roller assembly is in contact with the material surface, the hydraulic cylinder continues to drive the transmission frame to move downward. At this time, the transmission frame will transmit the downward pressure to the pressure ring through the spring, then to the annular pressure sensor, and finally to the friction roller assembly through the connecting plate. When the hydraulic cylinder is in different strokes, the spring will be in different compressed states, and the pressure it applies to the annular pressure sensor will also change accordingly. Therefore, the magnitude of the downward pressure applied by the friction roller assembly can be determined by the annular pressure sensor, which allows the user to adjust the stroke of the hydraulic cylinder so that the downward pressure applied by the friction roller assembly can meet the test conditions.

[0009] In one possible implementation, the transmission frame includes a transmission plate with guide rods fixedly connected to both ends of the plate and slidably connected to the supporting gantry. The hydraulic cylinder shaft is fixedly connected to the transmission plate. This structure can guide and limit the movement of the transmission plate through the guide rods, ensuring its stability during the up-and-down sliding process and preventing deviation.

[0010] In one possible implementation, the friction roller assembly includes two symmetrically arranged hinged plates with a rotatably connected roller shaft installed between them. A sleeve is fitted over the roller shaft, and a friction layer is adhered to the surface of the sleeve. In addition, limit wheels are threaded to both ends of the roller shaft. The above structure enables a detachable connection between the sleeve and the roller shaft, facilitating quick replacement of the friction layer after excessive wear.

[0011] In one possible implementation, the roller shaft surface is provided with a plurality of transmission grooves arranged in a circumferential array, and the inner wall of the sleeve is fixedly provided with a plurality of transmission ridges corresponding to the transmission grooves. In order to facilitate the design of quick replacement of the friction layer, the sleeve and the roller shaft need to be slidably connected, and the engagement of the transmission grooves and the transmission ridges can realize the transmission of torque between the sleeve and the roller shaft.

[0012] In one possible implementation, the rotation drive mechanism includes a motor bracket on which a drive motor is mounted, and two transmission wheels, which are respectively mounted on the shaft ends of the drive motor and the roller shaft. The transmission wheels are connected by a transmission belt. When it is necessary to drive the roller shaft to rotate, the drive motor works to drive the roller shaft through the transmission action of the transmission wheels and the transmission belt.

[0013] In one possible implementation, the feeding table includes a base with symmetrically arranged guide rails. A movable table plate is slidably mounted on the guide rails, and its lower end face is provided with a guide groove that slidably engages with the guide rails. This structure enables a sliding connection between the movable table plate and the base through the cooperation between the guide rails and the guide grooves, allowing the movable table plate to perform the feeding function by sliding.

[0014] In one possible implementation, a rotatable drive screw is mounted on the base plate, and a centrally located transmission block is provided on the lower end face of the movable platform. The drive screw is threadedly connected to the transmission block. During feeding, the drive screw can be rotated to drive the threaded transmission block to move, ultimately driving the movable platform to move forward stably and as uniformly as possible, thereby achieving the function of continuous feeding.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] When in use, the wear resistance tester uses a hydraulic cylinder to drive the transmission frame to move downward, causing the force measuring and pressing frame mounted on it to move downward so that the friction roller assembly comes into contact with the surface of the material to be tested. During the test, the friction roller assembly rotates at high speed to rub the material surface, while the material is conveyed forward by the feeding table. In the above process, since the friction roller assembly is always in contact with the material surface and the applied downward pressure is almost constant, the stability of the friction applied during the test can be ensured, and the material surface will not be impacted and deformed.

[0017] In addition, the spring force measuring mechanism inside the force measuring and pressing frame can transmit the downward pressure of the hydraulic cylinder and monitor the downward pressure applied to the friction roller assembly in real time. When simulating different test conditions, the magnitude of the force transmitted by the spring force measuring mechanism can be adjusted by controlling the stroke of the hydraulic cylinder, thereby measuring the wear resistance of the material surface under different downward pressure conditions.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 3 As shown, this embodiment provides an intelligent material surface abrasion resistance tester, including a feeding platform 1 on which a supporting frame 2 is mounted, a transmission frame 3 slidably mounted on the supporting frame 2, a hydraulic cylinder 4 mounted on the supporting frame 2 for driving the transmission frame 3 to move up and down, a force-measuring pressure frame 5 mounted on the lower side of the transmission frame 3, a friction roller assembly 6 mounted on the lower side of the force-measuring pressure frame 5, and a rotation drive mechanism 7 for driving the friction roller assembly 6 to rotate. The force-measuring pressure frame 5 includes a connecting plate 51, which is slidably connected to the transmission frame 3 via a sliding rod 52 connected thereon. Next, a spring force measuring mechanism is provided outside the sliding rod 52, which is used to monitor the downward pressure applied by the transmission frame 3 to the connecting plate 51. Based on the above scheme, during the test, since the friction roller assembly 6 is always in contact with the material surface and the downward pressure it applies is almost constant, the stability of the friction applied during the test can be ensured, and the material surface will not be impacted and deformed. In addition, when simulating different test conditions, the magnitude of the force transmitted by the spring force measuring mechanism is adjusted by controlling the stroke of the hydraulic cylinder 4, thereby measuring the wear resistance of the material surface under different downward pressure conditions.

[0028] The spring force measuring mechanism includes an annular pressure sensor 53 mounted on a connecting plate 51, with a pressure ring 54 slidably sleeved on a sliding rod 52. A force transmission spring 55 is mounted on the pressure ring 54, with its two ends abutting against the pressure ring 54 and the transmission frame 3, respectively. In addition, an anti-detachment end 56 is fixedly connected to the top of the sliding rod 52. When the friction roller assembly 6 is in contact with the material surface, the hydraulic cylinder 4 continues to drive the transmission frame 3 to move downward. At this time, the transmission frame 3 will transmit the downward pressure to the pressure ring 54 through the force transmission spring 55, then to the annular pressure sensor 53, and finally to the friction roller assembly 6 through the connecting plate 51. When the hydraulic cylinder 4 is in different strokes, the force transmission spring 55 will be in different compressed states, and the pressure it applies to the annular pressure sensor 53 will also change accordingly. Therefore, the magnitude of the downward pressure applied by the friction roller assembly 6 can be determined by the annular pressure sensor 53, which allows the user to adjust the stroke of the hydraulic cylinder 4 so that the downward pressure applied by the friction roller assembly 6 can meet the test conditions.

[0029] The transmission frame 3 includes a transmission plate 31, with guide rods 32 fixedly connected to both ends of the plate and slidably connected to the supporting gantry 2. The shaft end of the hydraulic cylinder 4 is fixedly connected to the transmission plate 31. This structure allows the guide rods 32 to guide and limit the movement, ensuring the stability of the transmission plate 31 during its up-and-down sliding and preventing deviation. Figure 2 As shown.

[0030] The friction roller assembly 6 includes two symmetrically arranged hinged plates 61, with a rotatably connected roller shaft 62 installed between them. A sleeve 63 is fitted over the roller shaft 62, and a friction layer 64 is adhered to the surface of the sleeve 63. Furthermore, limit wheels 65 are threaded to both ends of the roller shaft 62. This structure allows for a detachable connection between the sleeve 63 and the roller shaft 62, facilitating quick replacement of the friction layer 64 after excessive wear. The roller shaft 62 has several transmission grooves 621 arranged in a circumferential array on its surface, and the inner wall of the sleeve 63 is fixedly provided with several transmission ridges 631 corresponding to the transmission grooves 621. To facilitate the quick replacement of the friction layer 64, a sliding connection is required between the sleeve 63 and the roller shaft 62. The engagement of the transmission grooves 621 and the transmission ridges 631 enables torque transmission between the sleeve 63 and the roller shaft 62. Figure 4 As shown.

[0031] The rotation drive mechanism 7 includes a motor bracket 71 on which a drive motor 72 is mounted, and two transmission wheels 73, which are respectively mounted on the shaft ends of the drive motor 72 and the roller 62. The transmission wheels 73 are connected by a transmission belt 74. When the roller 62 needs to be driven to rotate, the drive motor 72 operates to drive the roller 62 through the transmission action of the transmission wheels 73 and the transmission belt 74. Figure 5 As shown.

[0032] The feeding table 1 includes a base 11 on which symmetrically arranged guide rails 12 are mounted. A movable table plate 13 is slidably mounted on the guide rails 12, and its lower end face has a guide groove 14 that slidably engages with the guide rails 12. This structure allows for a sliding connection between the movable table plate 13 and the base 11 through the cooperation between the guide rails 12 and the guide groove 14, enabling the movable table plate 13 to perform a feeding function through sliding. Figure 6 As shown, a rotatable drive screw 16 is installed on the base 11, and a centrally located transmission block 15 is provided on the lower end face of the movable platform 13. The drive screw 16 is threadedly connected to the transmission block 15. When feeding, the drive screw 16 can be rotated to drive the transmission block 15, which is threadedly connected to it, to move. Ultimately, the movable platform 13 is driven to move forward stably and as uniformly as possible, thus achieving the function of continuous feeding.

[0033] The working principle and usage process of this utility model:

[0034] When in use, the wear resistance tester drives the transmission frame 3 to move downward via the hydraulic cylinder 4, causing the force measuring pressure frame 5 mounted on it to move downward so that the friction roller assembly 6 comes into contact with the surface of the material to be tested. During the test, the friction roller assembly 6 rotates at high speed to rub the material surface, while the material is conveyed forward by the feeding table 1. In the above process, since the friction roller assembly 6 is always in contact with the material surface and the applied downward pressure is almost constant, the stability of the friction applied during the test can be ensured, and the material surface will not be impacted and deformed.

[0035] In addition, the spring force measuring mechanism inside the force measuring and pressing frame 5 can transmit the downward pressure of the hydraulic cylinder 4 and monitor the downward pressure applied to the friction roller assembly 6 in real time. When simulating different test conditions, the magnitude of the force transmitted by the spring force measuring mechanism can be adjusted by controlling the stroke of the hydraulic cylinder 4, thereby measuring the wear resistance of the material surface under different downward pressure conditions.

[0036] The spring force measuring mechanism includes an annular pressure sensor 53 mounted on a connecting plate 51, with a pressure ring 54 slidably sleeved on a sliding rod 52. A force transmission spring 55 is mounted on the pressure ring 54, with its two ends abutting against the pressure ring 54 and the transmission frame 3, respectively. In addition, an anti-detachment end 56 is fixedly connected to the top of the sliding rod 52. When the friction roller assembly 6 is in contact with the material surface, the hydraulic cylinder 4 continues to drive the transmission frame 3 to move downward. At this time, the transmission frame 3 will transmit the downward pressure to the pressure ring 54 through the force transmission spring 55, then to the annular pressure sensor 53, and finally to the friction roller assembly 6 through the connecting plate 51. When the hydraulic cylinder 4 is in different strokes, the force transmission spring 55 will be in different compressed states, and the pressure it applies to the annular pressure sensor 53 will also change accordingly. Therefore, the magnitude of the downward pressure applied by the friction roller assembly 6 can be determined by the annular pressure sensor 53, which allows the user to adjust the stroke of the hydraulic cylinder 4 so that the downward pressure applied by the friction roller assembly 6 can meet the test conditions.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
