[0002] Across a wide range of materials science and industrial applications, evaluating the wear resistance of a material's surface is a critical step in ensuring product quality and service life. Traditional wear testing machines typically use hard materials such as grinding wheels and falling sand as abrasive media, simulating the impact and friction of these hard abrasives on the material surface to assess its wear resistance.

[0003] However, some materials, such as touch screens of smartphones and tablets, and flexible displays, have surface coatings and display layers that are mainly affected by flexible wear objects such as finger touch, clothing friction, and possible wiping with cleaning cloths during daily use.

[0004] Traditional hard wear testing machines cannot accurately simulate the contact and friction characteristics between flexible wear objects and material surfaces due to the use of hard wear media. Therefore, the test results are often difficult to reflect the wear resistance performance of the material in actual use. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] refer to Figure 1-4 A steel wool wear tester includes an operating platform 1, a clamping assembly 2, a reciprocating device 3, a wear test assembly 4 and a counting device 6. The operating platform 1 serves as the base of the entire tester, providing a stable support surface. At the same time, a circuit board can be set inside, and buttons, display screens and other structures can be set on the outer surface to realize the control of the tester.

[0023] The clamping assembly 2 is arranged on the operating platform 1 and includes two moving blocks 21. Each moving block 21 is provided with a clamping plate 22 for clamping the sample to be tested. The clamping plate 22 can be arranged on the upper half of the moving block 21 and protrude from the top surface of the moving block 21 to prevent the clamping plate 22 from affecting the movement of the moving block 21.

[0024] An adjusting device 5 is provided between the moving block 21 and the operating platform 1, and the adjusting device 5 consists of a first fixed block 51, a second fixed block 52, a connecting rod 53, a screw 54 and a rotating wheel 55. The first fixed block 51 is located in the middle of the operating platform 1, and the second fixed block 52 is symmetrically arranged on both sides. The connecting rod 53 passes through the first fixed block 51 and the two moving blocks 21, and plays a guiding role. The screw 54 passes through the second fixed block 52 and is screwed to the moving block 21. One end is rotatably connected to the first fixed block 51, and the other end is connected to the rotating wheel 55 for easy manual adjustment. By rotating the rotating wheel 55, the screw 54 can be driven to rotate. Since the two ends of the moving block 21 are sleeved on the connecting rod 53, the rotation of the screw 54 is converted into the movement of the moving block 21, and then drives the moving block 21 to move along the connecting rod 53, so as to adjust the distance between the two splints 22 to adapt to samples of different sizes to be tested. The sides of the clamping plates 22 that are close to each other are provided with anti-slip grooves to increase the friction between the clamping plates 22 and the sample to be tested, thereby improving the clamping force and improving the stability of the sample to be tested being clamped.

[0025] A reciprocating moving device 3 is provided on the operating platform 1, and the reciprocating moving device 3 includes a moving seat 31. The moving seat 31 can be an aluminum profile. The moving seat 31 is horizontally arranged on the operating platform 1. A moving motor 32 is provided on one side of the moving seat 31. The moving motor 32 can be a stepping motor. A driving wheel is provided on the output shaft of the moving motor 32, and a driven wheel is provided on the other side of the moving seat 31. A transmission belt 33 is provided between the driving wheel and the driven wheel. A slide 34 is provided on the transmission belt 33, which can be connected by a bolt assembly. The slide 34 is slidably connected to the moving seat 31. At least two pulleys can be provided at the bottom and top of the slide 34 to ensure that the slide 34 can move back and forth along the moving seat 31. A wear-resistant test component 4 is connected to the slide 34.

[0026] The moving motor 32 drives the driving wheel to rotate, thereby driving the transmission belt 33 to move, and further driving the wear-resistant test assembly 4 to reciprocate through the movement of the slide plate 34.

[0027] The wear-resistant test assembly 4 is connected to the reciprocating device 3. The wear-resistant test assembly 4 is arranged above the sample to be tested. The wear-resistant test assembly 4 includes a clamping plate 41. The clamping plate 41 is connected to the slide 34 and moves with the slide 34. The clamping plate 41 is penetrated by a T-shaped sleeve 42. A fixing rod 43 is inserted into the T-shaped sleeve 42. The fixing rod 43 can slide in the T-shaped sleeve 42. A wear-resistant part 44 is provided at the bottom of the fixing rod 43. The wear-resistant part 44 includes a wear-resistant flat head 441 and a locking block 442. The wear-resistant flat head 441 can be a square block, and the locking block 442 can be a square slot block. The flat head 441 is screwed together with the bottom of the fixing rod 43, which can realize a detachable connection between the wear-resistant flat head 441 and the fixing rod 43, which is convenient for the installation of steel wool and the replacement of wear-resistant parts 44 of different materials; a locking block 442 is provided on the wear-resistant flat head 441, and a bolt is passed through the locking block 442, which is screwed together with the wear-resistant flat head 441, and steel wool is provided between the wear-resistant flat head 441 and the locking block 442. The steel wool is coated on the bottom of the wear-resistant flat head 441 to ensure that it can fit tightly on the surface of the sample to be tested during the test, thereby realizing the wear-resistant test of the sample to be tested.

[0028] A support rod 45 is coaxially provided on the top of the fixed rod 43. The support rod 45 can be screwed together with the fixed rod 43. The rod diameter of the support rod 45 is smaller than the rod diameter of the fixed rod 43, so that a placement platform is formed at the connection between the support rod 45 and the fixed rod 43; a counterweight 46 is sleeved on the support rod 45, and the counterweight 46 can be a weight. The counterweight 46 is arranged above the clamping plate 41. By placing weights of different weights and quantities on the support rod 45, the pressure applied to the wear-resistant part 44 can be adjusted, thereby simulating different wear conditions.

[0029] The counting device 6 includes two sensors 61 symmetrically positioned on the movable base 31 and secured with bolts. The position of the sensors 61 on the movable base 31 can be adjusted to accommodate wear tests on samples of varying sizes. Sensor plates 62 are symmetrically positioned on either side of the slide 34. When the slide 34 reaches the position of the sensors 61, the sensors 62 trigger the sensors 61, recording one reciprocating motion. By accumulating the number of triggering events, the number of wear test cycles can be accurately counted. The sensors 61 are also connected to the movable motor 32. When the sensors 62 trigger the sensors 61, they send a signal to the movable motor 32, causing it to stop or reverse rotation, preventing the slide 34 from sliding beyond the set travel range.

[0030] The specific working principle is as follows:

[0031] The sample to be tested is placed between the clamping plates 22 of the clamping assembly 2 and on the first fixing block 51 . The distance between the two clamping plates 22 is adjusted by rotating the rotating wheel 55 so that the sample to be tested is firmly clamped at the set position.

[0032] Wrap steel wool around the bottom of the wear-resistant flat head 441, set a locking block 442 on the wear-resistant flat head 441, and lock it with bolts. Fix the installed wear-resistant part 44 to the bottom of the fixing rod 43 so that the wear-resistant part 44 fits the surface of the sample to be tested. According to the simulation conditions, select a counterweight 46 of appropriate weight and install the counterweight 46 on the support rod 45 to achieve the pressure required for the test.

[0033] The moving motor 32 is activated, driving the driving wheel to rotate. This, in turn, drives the slide 34 and the wear test assembly 4 back and forth on the moving base 31 via the transmission belt 33. The steel wool at the bottom of the wear-resistant member 44 continuously rubs against the surface of the test sample during movement, simulating the wear process in actual use.

[0034] The counting device 6 records the reciprocating times of the slide plate 34 in real time, that is, the number of cycles of the wear test. When the preset test times are reached or obvious wear is observed on the surface of the sample, the motor is turned off and the test is stopped.

[0035] Evaluate the wear resistance of the sample to be tested and conduct subsequent analysis or adjust the test parameters based on the test results.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
