Description

Technical Field

[0001] This invention relates to the field of wear detection technology, and in particular to a wear testing apparatus. Background Technology

[0002] Wear is an inevitable result of friction; it is the phenomenon of continuous deformation or loss of surface materials when objects in contact undergo relative motion. Therefore, wear not only affects material consumption but is also a crucial factor determining the service life of devices or parts. Currently, with the continuous development of science and technology, numerous new materials are being invented and applied to various sectors of the national economy. Many sectors of the national economy have a demand for mortar or slurry transportation, requiring high-performance wear-resistant materials. Therefore, there is a need for testing equipment capable of detecting the wear performance of various mortar materials and studying their wear mechanisms.

[0003] Currently available wear testing devices all use the method of rotating the sample to generate friction with the medium. In actual operation, the medium will move under the influence of the sample, resulting in inaccurate control of the erosion angle of the medium on the sample, which in turn affects the experimental results. Summary of the Invention

A detection through hole and a receiving groove communicating with the detection through hole are provided on the planar inner wall.

[0008] The sample fixture includes a second driving device and a sample mounting plate. The second driving device is connected to the sample mounting plate in a transmission manner. The material sample can be fixed on the sample mounting plate. The second driving device drives the sample mounting plate to move the material sample into the detection through hole and fix it at the test position. The material sample has a test surface facing away from the sample mounting plate. When the material sample is located at the test position, the test surface and the inner wall of the plane are on the same plane.

[0009] The container contains an experimental medium, the height of which is higher than the height of the detection through-hole in the vertical direction. The stirring component can extend into the experimental medium. The first driving device is connected to the stirring component and drives the experimental medium to rotate and flow in the container through the stirring component, so that the experimental medium can rub against the test surface of the material sample fixed in the detection through-hole. The thickness detection device is fixed in the receiving groove and detects the thickness value of the material sample in the direction perpendicular to the test surface in real time.

[0010] Preferably, it also includes a control terminal;

[0011] The control terminal is electrically connected to the thickness detection device and the second driving device respectively. The thickness detection device sends the thickness value of the material sample along the direction perpendicular to the test surface to the control terminal in real time.

The control terminal displays the flow rate information of the experimental medium sent by the flow rate detector through the display and stores it in the memory.

[0025] Preferably, the lifting device includes a third drive device and a screw lifting mechanism;

[0026] The third driving device is fixed on the base plate and connected to the support plate through the screw lifting mechanism, so that the third driving device drives the support plate through the screw lifting mechanism to move the tank along the axis of the column.

[0027] Preferably, it also includes end caps;

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the wear testing apparatus of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0038] Example 1

[0039] like Figure 1 , 2 As shown, a wear testing apparatus for conducting wear tests on a material sample 1 includes a tank 2, a stirring component 3, a sample fixture 4, a first driving device 11 (which may be a motor), and a thickness detection device 5. The tank 2 is a cylindrical body with an opening 6 at one end, vertically positioned with the opening 6 facing upwards. The tank 2 has a planar inner wall 7 extending vertically, on which a detection through-hole 8 and a receiving groove 9 communicating with the detection through-hole 8 are provided. The sample fixture 4 includes a second driving device 12 (which may be a motor) and a sample mounting plate 13. The second driving device 12 is connected to the sample mounting plate 13, allowing the material sample 1 to be fixed on the sample mounting plate 13. The second driving device 12 drives the sample mounting plate 13, causing the material sample 1 to extend into the detection through-hole 8 and be fixed in the test position. The material sample 1 has a test surface 14 facing away from the sample mounting plate 13. When the material sample 1 is in the test position, the test surface 14 and the planar inner wall 7 are on the same plane. The tank 2 contains experimental medium 15 (which may be mortar). The height of the experimental medium 15 in the vertical direction is higher than the height of the detection through hole 8. The stirring component 3 can extend into the experimental medium 15. The first driving device 11 is connected to the stirring component 3. The first driving device 11 drives the experimental medium 15 to rotate and flow in the tank 2 through the stirring component 3, so that the experimental medium 15 can rub the test surface 14 of the material sample 1 fixed in the detection through hole 8. The thickness detection device 5 is fixed in the receiving groove 9 and detects the thickness value of the material sample 1 in the direction perpendicular to the test surface 14 in real time.

[0040] Using this technical solution, when the experimental medium 15 rubs the test surface 14 of the material sample 1, the material sample 1 remains in a fixed state. This allows for precise control of the erosion angle of the experimental medium 15 on the test surface 14, thereby ensuring the experimental results. The thickness detection device 5 can be any device capable of achieving the purpose of the invention. It should be noted that when the thickness detection device 5 measures the thickness of the material sample 1 through optical action, it can be as follows: Figure 2As shown, a partition 10 made of transparent material is provided at the connection between the detection through-holes 8 and 8. This separates the thickness detection device 5 from the material sample 1 while ensuring the reliability of the thickness measurement results of the material sample 1 by the thickness detection device 5. In actual manufacturing, the thickness detection device 5 and the material sample 1 can be attached to opposite sides of the partition 10 to prevent the experimental medium 15 from entering between the thickness detection device 5 and the partition 10 or between the material sample 1 and the partition 10, thereby ensuring the measurement effect. It should be noted that in actual manufacturing, there are more than two detection through-holes 8, the number of thickness detection devices 5 is equal to the number of detection through-holes 8 and corresponds one-to-one, and the number of sample fixtures 4 is equal to the number of detection through-holes 8 and corresponds one-to-one.

[0041] Example 2

[0042] Based on Embodiment 1, a control terminal (not shown) is also included. The control terminal is electrically connected to the thickness detection device 5 and the second driving device 12. The thickness detection device 5 sends the thickness value of the material sample 1 along the direction perpendicular to the test surface 14 to the control terminal in real time. The control terminal controls the second driving device 12 to adjust the position of the material sample 1 based on the received thickness value change. For example, when the thickness of the material sample 1 decreases by 1 mm under the friction of the experimental medium 15, the control terminal can control the second driving device 12 to drive the material sample 1 to move 1 mm in the axial direction of the tank 2, so that the test surface 14 remains on the same plane as the inner wall 7, avoiding changes in the erosion angle of the test surface 14 by the experimental medium 15.

[0043] Furthermore, such as Figure 1 As shown, the system also includes a flow rate detector 16, and a control terminal with a display and a memory. The flow rate detector 16 is electrically connected to the control terminal and is fixedly connected to the inner wall of the tube body, located within the experimental medium 15. It is used to detect the flow rate information of the experimental medium 15 in real time and send this information to the control terminal. The control terminal displays the flow rate information of the experimental medium 15 received from the flow rate detector 16 on the display and stores it in the memory. The control terminal also displays the thickness value of the received material sample 1 along the direction perpendicular to the test surface 14 on the display and stores it in the memory. This allows for real-time display and recording of the flow rate of the experimental medium 15 and the corresponding thickness change value of the material sample 1, facilitating the analysis of experimental results.

[0044] Example 3

[0045] Based on Embodiment 1 or Embodiment 2, such as Figure 3As shown, the stirring component 3 includes a rotating shaft 17 and blades 18. One end of the rotating shaft 17 is connected to the first driving device 11, and the other end is a free end (not shown in the figure). The blades 18 are fixedly connected to the free end and extend in a direction away from the rotating shaft 17 in a direction perpendicular to the axis of the rotating shaft 17.

[0046] In actual production, there are at least two blades 18, and the at least two blades 18 are arranged in a circular array with the axis of rotation 17 as the center.

[0047] Example 4

[0048] Based on embodiment three, such as Figure 1 As shown, it also includes a column 19, a crossbeam 20, and a support plate 21. The column 19 is vertically arranged, the crossbeam 20 is connected to the top of the column 19, and the support plate 21 is movably connected to the column 19 and is located below the crossbeam 20 in the vertical direction. The tank body 2 is set on the support plate 21. It should be noted that the second drive device can also be fixedly installed on the support plate 21 at this time. The first drive device 11 is installed on the crossbeam 20, the rotating shaft 17 is vertically arranged, and the bottom end is a free end located below the first drive device 11 and corresponding to the opening 6 of the tank body 2.

[0049] By adopting this technical solution, the support plate 21 can be moved up and down along the column 19 to make the tank 2 move in the vertical direction, so that the blades of the stirring component 3 can be inserted into the experimental medium 15 in the tank 2 through the opening 6 of the tank 2, or detached from the tank 2.

[0050] Furthermore, such as Figure 1 As shown, it also includes a lifting device 23 and a base plate 22;

[0051] The base plate 22 is horizontally set and fixedly connected to the column 19. The base plate 22 is located below the support plate 21. The lifting device 23 is set on the base plate 22 and is connected to the support plate 21 for transmission, so as to drive the support plate 21 to move the tank 2 along the axis of the column 19.

[0052] Specifically, such as Figure 1 As shown, the lifting device 23 includes a third drive device 24 (which may be a motor) and a screw lifting mechanism 25. The third drive device 24 is fixed on the base plate 22 and is connected to the support plate 21 through the screw lifting mechanism 25, so that the third drive device 24 drives the support plate through the screw lifting mechanism 25 to move the tank 2 along the axis of the column 19.

[0053] Example 5

[0054] Based on any of the above embodiments, such as Figure 1 , 2As shown, it also includes a sealing end cap 26. The sample fixture 4 also includes a drive shaft 27, with both ends of the drive shaft 27 connected to the second drive device 12 and the sample mounting plate 13, respectively, so that the second drive device 12 drives the material sample 1 to move through the drive shaft 27 and the sample mounting plate 13. The sealing end cap 26 has a through hole (not shown in the figure), and the sealing end cap 26 is sleeved on the drive shaft 27 through the through hole and is detachably connected to the outer wall of the tank 2 to seal the detection through hole 8. By sealing the detection through hole 8 with the sealing end cap 26, the leakage of the experimental medium 15 through the detection through hole 8 can be prevented.

[0055] Furthermore, such as Figure 2 As shown, it also includes a first sealing component 28, which is annular. The first sealing component 28 is sleeved on the drive shaft 27 and located between the sealing end cap 26 and the outer wall of the tank body 2, to seal the gap between the sealing end cap 26 and the outer wall of the tank body 2. This prevents the experimental medium 15 from flowing out from the gap between the sealing end cap 26 and the outer wall of the tank body 2.

[0056] And / or, it also includes a second sealing component 29, which is annular and sleeved on the drive shaft 27, located between the drive shaft 27 and the inner wall of the through hole, to seal the gap between the drive shaft 27 and the inner wall of the through hole. This prevents the experimental medium 15 from flowing out from the gap between the drive shaft 27 and the inner wall of the through hole.

[0057] The above embodiments enable the present invention to have the advantage of being able to precisely control the erosion angle of the experimental medium on the material sample, thereby ensuring the experimental results.

[0058] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
