Description

Technical Field

[0001] The utility model relates to the technical field of mesh wear resistance detection, in particular to a mesh material wear resistance detection device. Background Technique

[0002] Mesh is a building material used for roof support in coal mines, tunnels, bridge construction, roadbed mesh reinforcement, and construction sites. The wear resistance of mesh materials mainly depends on their materials and manufacturing processes. Different materials have different wear resistance properties and are suitable for different application scenarios. Materials such as stainless steel mesh, manganese steel mesh, and steel plate sieve mesh exhibit different degrees of wear resistance due to their respective physical properties and manufacturing processes and are suitable for different industrial application scenarios. Selecting the appropriate mesh material is crucial for ensuring its performance and lifespan in a specific working environment; during the research and development process of high-precision, high-temperature, and wear-resistant mesh materials, it is necessary to detect the wear resistance of the mesh;

[0003] However, the existing mesh material wear resistance detection devices can only detect one side of the mesh. When detecting the wear resistance of the other side of the mesh, manual flipping by workers is mostly required, which may cause workers to be scratched by the mesh and reduce the detection efficiency of the mesh wear resistance at the same time; therefore, we need to propose a mesh material wear resistance detection device.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-5 shown, a wear resistance detection device for mesh materials includes an installation base plate 1 and a rotating column 16. An electric push rod 2 is fixedly arranged on the upper surface of the installation base plate 1. A grinding wheel 3 is arranged on the upper surface of the installation base plate 1 and at the working end of the electric push rod 2. A fixed clamping plate 4 is fixedly arranged on one side of the rotating column 16 close to the grinding wheel 3. And a moving clamping plate 5 is slidably arranged above the fixed clamping plate 4 at one end of the rotating column 16. A turnover assembly for driving the fixed clamping plate 4 and the moving clamping plate 5 to turnover is arranged on the upper surface of the installation base plate 1. The turnover assembly includes a connecting block 11, a moving module and a limiting module. The rotating column 16 is rotatably arranged inside the connecting block 11. The moving module is arranged on the upper surface of the installation base plate 1 and on one side of the connecting block 11.

[0025] The utility model clamps the mesh of the same thickness through the fixed clamping plate 4 and the moving clamping plate 5, so as to ensure that the mesh is located at the center of the rotating column 16, and further ensure that the mesh can contact the grinding wheel 3 after turnover. And the electric push rod 2 is driven to drive the grinding wheel 3 to move back and forth, so as to perform grinding tests on different positions of the mesh.

[0026] Furthermore, the moving module includes a mounting frame 8, a servo motor 9, a lead screw 10, and a moving bump 20. The mounting frame 8 is fixedly installed on the upper surface of the mounting base plate 1. The servo motor 9 is bolted to the top of the mounting frame 8. The lead screw 10 is rotatably arranged inside the mounting frame 8, and the lead screw 10 penetrates through the top of the mounting frame 8 and is key-connected to the servo motor 9. The moving bump 20 is threadedly sleeved on the outer arc surface of the lead screw 10, and the connecting block 11 is fixedly connected to the moving bump 20. With the above design, when the servo motor 9 is started to drive the lead screw 10 to rotate, the lead screw 10 drives the moving bump 20 to move up and down through the thread, thereby driving the connecting block 11 to move up and down. Moreover, the moving bump 20 is set as a convex block, so as to ensure that when the lead screw 10 drives the moving bump 20 to move up and down, the moving bump 20 will not rotate along with the lead screw 10.

[0027] Furthermore, the limiting module includes a moving frame 6, a limiting plate 7, a support block 13, and a triangular guiding block 15. The support block 13 is fixedly installed on the upper surface of the mounting base plate 1 and is located between the mounting frame 8 and the grinding wheel 3. The moving frame 6 is slidably arranged on the upper surface of the support block 13. The triangular guiding block 15 is fixedly arranged at the inner bottom end of the moving frame 6. There are two groups of limiting plates 7, and the two groups of limiting plates 7 are symmetrically arranged at the top of the moving frame 6. With the above design, the triangular guiding block 15 is arranged at the central position of the inner bottom end of the moving frame 6, and the moving frame 6 is slidably arranged inside the support block 13, and the bottom end of the moving frame 6 is set as a trapezoidal block, so as to prevent the moving frame 6 from disengaging from the inside of the support block 13. When the guiding column 18 moves down and contacts the triangular guiding block 15, it will drive the moving frame 6 to move left and right through the triangular guiding block 15, so as to ensure that after flipping, the other group of guiding columns 18 will contact the corresponding limiting plate 7.

[0028] Furthermore, the limiting module further includes an extension block 17 and a guiding column 18. There are two groups of extension blocks 17 and guiding columns 18 respectively. The two groups of extension blocks 17 are fixedly installed on the outer arc surface of the rotating column 16, and the two groups of guiding columns 18 are respectively arranged on the side of the extension block 17 away from the connecting block 11. With the above design, when the mesh is flipped, the guiding column 18 contacts a group of limiting plates 7. At this time, the guiding column 18 continues to move upward. Under the action of the limiting plate 7, the guiding column 18 drives the rotating column 16 to rotate. And at this time, the other group of guiding columns 18 will leave the moving frame 6 through the distance between the two groups of limiting plates 7, thus completing the flipping of the mesh. After the flipping is completed, the moving module drives the rotating column 16 to move down as a whole. And at this time, the group of guiding columns 18 located below will contact the triangular guiding block 15 and descend along the inclined surface on one side of the triangular guiding block 15, thereby pushing the triangular guiding block 15 to move, and further ensuring that when flipping again, the guiding column 18 above will contact the other group of limiting plates 7, thereby driving the mesh to flip.

[0029] Furthermore, an extension plate 14 is fixedly installed at the bottom end of the connecting block 11. One end of the rotating column 16 rotatably penetrates through the support block 13 and is fixedly connected to a connecting plate 19. A compression spring 12 is fixedly installed between the extension plate 14 and the connecting plate 19. In the above design, two groups of limiting blocks are symmetrically arranged at one end of the connecting block 11 close to the connecting plate 19 with the rotating column 16 as the center, so as to ensure that the connecting plate 19 can only rotate along the upper half of the connecting block 11. When the mesh is in a horizontal state, the extension plate 14 and the connecting plate 19 are in a vertical state, and at this time, the stretching of the compression spring 12 is in the minimum state. When the rotating column 16 rotates, the connecting plate 19 will move away from the extension plate 14, and at this time, the compression spring 12 will be stretched. When the rotating column 16 rotates to the other side of the connecting block 11, the compression spring 12 will quickly drive the connecting plate 19 to rotate to the position with the minimum tension on the other side, so as to ensure that the mesh remains in a horizontal state every time it is flipped.

[0030] Furthermore, the included angle between the two groups of extension blocks 17 is set to 120 degrees, and the two groups of guide posts 18 are in contact with the triangular guide block 15. In the above design, the two groups of extension blocks 17 are set to 120 degrees to ensure that the guide posts 18 after flipping can be in contact with the triangular guide block 15, so as to drive the moving frame 6 to move through the triangular guide block 15, and further ensure that the upper guide posts 18 can be in contact with the corresponding limiting plates 7 during the next flip.

[0031] Furthermore, the two groups of guide posts 18 are not in contact with the moving frame 6, and the guide posts 18 are in contact with the limiting plates 7. In the above design, the guide posts 18 not being in contact with the moving frame 6 avoids rubbing, and the guide posts 18 can be in contact with the limiting plates 7 to ensure that the rotating column 16 can be driven to rotate 180 degrees, and further drive the mesh to flip.

[0032] Working principle: Place the mesh between the fixed clamping plate 4 and the moving clamping plate 5, and then move the moving clamping plate 5 to clamp the mesh on the upper surface of the grinding wheel 3. Rotate the grinding wheel 3 to grind the mesh to test the wear resistance of the mesh. When it is necessary to grind the other side of the mesh, start the servo motor 9 to drive the lead screw 10 to rotate. The lead screw 10 drives the connecting block 11 to move upward through the moving convex block 20. When a group of guide posts 18 are in contact with a group of limiting plates 7, the connecting block 11 still continues to move upward. At this time, the guide posts 18 are blocked by the limiting plates 7, and the guide posts 18 will drive the rotating column 16 to rotate under the pressure of the limiting plates 7. And under the action of the compression spring 12, it is ensured that the rotating column 16 rotates 180 degrees, and further drives the mesh to flip. After the mesh flips, drive it to move downward for grinding through the moving assembly, so that the two sides of the mesh can be tested without manual operation by the staff.
