Description

Technical Field

[0001] This utility model relates to the field of testing machines, specifically an abrasion testing machine. Background Technology

[0002] An abrasion testing machine is a specialized testing device used to simulate the changes in the properties of materials under friction and wear conditions. It is widely used in the evaluation of abrasion resistance in rubber, plastics, metals, composite materials, and other fields. Its basic principle is to simulate the wear process in actual working conditions by having a rotating component (such as a grinding wheel, sandpaper, or a specific friction pair) come into contact with the sample to be tested, applying pressure under controlled conditions and generating relative motion.

[0003] In the existing technology, the clamping structure of abrasion testing machines is mostly fixed, such as directly connected to the main body of the equipment by bolts or welding. This results in the following limitations in adjusting the clamping position: Traditional clamping structures rely on bolt fastening or direct welding, which cannot change the sample position and make it difficult to make real-time dynamic adjustments during the test. Therefore, wear tests can only be performed on the middle of the sample, and the position cannot be adjusted to test other parts of the sample's sides. Due to the poor flexibility of position adjustment, it is difficult to meet the multi-position and multi-parameter testing requirements of complex samples. Utility Model Content

A partition is vertically arranged inside the housing. Two horizontally placed sliding rods are arranged symmetrically inside the housing. Both ends of the sliding rods are fixedly connected to the housing. Each sliding rod is provided with a slider, which is slidably connected to the sliding rod. A fixing plate is provided at one end of the slider, and a clamping plate is provided at the bottom of the fixing plate. Two fastening seats are arranged inside the housing, and a horizontally placed limiting rod is arranged between the two fastening seats. The clamping plate is engaged with the surface of the limiting rod.

[0006] Furthermore, a detachable clamping block is provided at the bottom of the clamping disk, and a gap is formed between the clamping block and the rotating roller.

[0007] Furthermore, a connecting rod is provided at one end of the slider, and a rectangular limiting groove is provided on the surface of the housing, with one end of the connecting rod extending to the outside of the limiting groove.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is combined Figures 1-5A detailed description of an abrasion testing machine according to this utility model is provided below:

[0021] A wear testing machine includes a housing 1. A rotating motor 12 and a rotating roller 5 are disposed inside the housing 1. The rotating motor 12 is rotatably connected to the rotating roller 5 via a chain. Both ends of the rotating roller 5 are rotatably connected to the housing 1. A partition 13 is vertically disposed inside the housing 1. Two horizontally arranged sliding rods 16 are disposed inside the housing 1, symmetrically arranged between them. Both ends of the sliding rods 16 are fixedly connected to the housing 1. A slider 15 is disposed on each sliding rod 16, and the slider 15 is slidably connected to the sliding rod 16. A fixing plate is disposed at one end of the slider 15, and a clamping plate 9 is disposed at the bottom of the fixing plate. Two fastening seats 7 are disposed inside the housing 1, and a horizontally arranged limiting rod 8 is disposed between the two fastening seats 7. The clamping plate 9 is engaged with the surface of the limiting rod 8.

[0022] The bottom of the clamping disk 9 is provided with a detachable clamping block 10, and a gap is formed between the clamping block 10 and the rotating roller 5. One end of the slider 15 is provided with a connecting rod 6. The surface of the housing 1 is provided with a rectangular limiting groove 14. One end of the connecting rod 6 extends to the outside of the limiting groove 14. The surface of the housing 1 is provided with a square mounting opening 2 and a round hole 3. The surface of the housing 1 is provided with a plurality of heat dissipation holes 4, and adjacent heat dissipation holes 4 are evenly distributed. One end of the clamping disk 9 is provided with an adjustment handle 11.

[0023] The connecting rod 6 extends to the outside of the limiting groove 14, facilitating manual adjustment of the slider 15 position from the outside, avoiding frequent opening and closing of the housing 1, and reducing operational complexity. The limiting groove 14 restricts the movement range of the connecting rod 6, preventing the slider 15 from derailing or excessive displacement, thus improving equipment operating safety. The design of the mounting port 2 and the round hole 3 facilitates the installation of the control panel and power switch, enhancing the expandability of the testing machine. Furthermore, the control panel installed in the mounting port 2 is electrically connected to the rotating motor 12, allowing control of the rotating motor 12 to start or stop. By winding sandpaper on the rotating roller 5 and fixing the test sample using the clamping plate 9 and clamping block 10, the test is completed. The motor 12 drives the rotating roller 5 to rotate, causing the test sample to rub against the sandpaper, thereby testing the abrasion resistance of the test sample. The working principle and process of the abrasion tester will not be described in detail here. The equidistantly arranged heat dissipation holes 4 form a uniform airflow channel, effectively dissipating the heat generated by the rotating motor 12. The adjustment handle 11 is integrated into one end of the clamping plate 9, enabling one-handed quick locking / releasing of the test sample, reducing the physical exertion of the operator and improving the testing efficiency. The internal space of the machine casing 1 is divided by the partition 13, effectively isolating the transmission area and the testing area, preventing debris from splashing and adhering to the slide bar 16 and the slider 15, causing the slider 15 to jam when sliding.

[0024] The wear testing machine of this embodiment achieves flexible adjustment of the lateral position of the clamping plate 9 through the sliding cooperation of the slide rod 16 and the slider 15, and the meshing structure of the clamping plate 9 and the limiting rod 8. It can adjust the clamping position in real time, which facilitates the wear testing machine to perform grinding tests on samples at various positions.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
