Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A device for testing the mechanical properties and conductivity of aluminum alloys, comprising:

[0028] Inspection table 1, support frame 2 is installed on inspection table 1, high-speed camera 37 is installed on inspection table 1, connecting rope 3 is connected to support frame 2 through winding mechanism, winding mechanism includes servo motor 15, winding rod 16 and two support blocks 17, two support blocks 17 are fixedly installed on support frame 2, winding rod 16 is rotatably connected between two support blocks 17, servo motor 15 is installed on support frame 2, and the output end of servo motor 15 is connected to the extension end of winding rod 16 through support block 17, and connecting rope 3 is connected to winding rod 16;

[0029] When the height of the impact block 5 is adjusted, the controller 36 controls the servo motor 15 to start. The servo motor 15 drives the winding rod 16 to rotate between the support blocks 17, winding or releasing the connecting rope 3, thereby precisely adjusting the height of the moving block 4 and the connected impact block 5 to simulate impact conditions under different working conditions.

[0030] The other end of the connecting rope 3 is connected to the moving block 4. The moving block 4 is connected to the impact block 5 on both sides through the locking assembly. The support frame 2 is provided with a limiting mechanism for limiting the moving block 4. The limiting mechanism includes a limiting frame 18 and two limiting plates 19. The limiting frame 18 is fixedly connected to the support frame 2. A limiting groove 20 is opened in the limiting frame 18. The limiting plates 19 are slidably connected in the limiting groove 20. The limiting mechanism also includes a first servo electric cylinder 21, a moving plate 22 and several locking plates 23. The first servo electric cylinder 21 is fixedly installed on the limiting frame 18. The output end of the first servo electric cylinder 21 is connected to the moving plate 22. Several locking plates 23 are fixedly connected to the moving plate 22. A through hole 24 is opened on the limiting frame 18 for the locking plates 23 to pass through. The locking plates 23 are in contact with the limiting plates 19.

[0031] The impact block 5 is positioned and locked. When the impact block 5 reaches the predetermined height, the controller 36 starts the first servo cylinder 21. The first servo cylinder 21 pushes the moving plate 22, which drives the locking plate 23 to pass through the through hole 24 of the limiting frame 18. One of the locking plates 23 is in contact with the limiting plate 19 to ensure that the impact block 5 is fixed in position before impact. When the moving block 4 moves, the limiting plate 19 moves in the limiting groove 20 to limit the moving block 4.

[0032] During the impact test, after positioning is completed, the controller 36 controls the servo motor 15 to reverse and release the connecting rope 3. Then, the first servo cylinder 21 pushes the moving plate 22 and the locking plate 23 to move, so that the locking plate 23 separates from the limiting plate 19, allowing the impact block 5 to fall freely under the action of gravity and impact the aluminum alloy sample. The high-speed camera 37 captures the dynamic deformation process of the material at the moment of impact at a high frame rate. By adjusting the height of the impact block 5, the impact energy is changed. Combined with the image data recorded by the high-speed camera 37, the deformation data of the test material at different impact block heights can be obtained, thereby scientifically evaluating the impact resistance performance index of the aluminum alloy material.

[0033] Based on the above embodiment, mounting plates 25 are fixedly installed on both sides of the support frame 2, and a second servo electric cylinder 26 is fixedly installed on the mounting plate 25. The output end of the second servo electric cylinder 26 is connected to a clamping frame 27.

[0034] When clamping the aluminum alloy sample, the aluminum alloy sample is placed on the testing table 1, and the second servo electric cylinder 26 drives the clamping frame 27 to clamp and fix the aluminum alloy sample on the testing table 1.

[0035] The engaging assembly includes an L-shaped plate 6, a triangular block 7, and a return spring 8. An impact block 5 has a mounting groove 9, and the return spring 8 is installed in the mounting groove 9. One end of the L-shaped plate 6 passes through the mounting groove 9, and one end of the return spring 8 is connected to the L-shaped plate 6. A engaging groove 10 is provided on the moving block 4. The triangular block 7 is fixedly connected to one end of the L-shaped plate 6, and the triangular block 7 passes through the mounting groove 9 and engages in the engaging groove 10.

[0036] When replacing impact blocks 5 of different weights, the operator manually presses the L-shaped plate to compress the return spring 8, causing the triangular block 7 to disengage from the engaging groove 10 of the moving block 4, thus quickly removing the impact block 5. When installing a new impact block 5, the L-shaped plate is released, and the return spring 8 pushes the triangular block 7 into the engaging groove 10, completing the quick replacement.

[0037] An electric push rod 11 is connected to the testing table 1 via an adjustment mechanism. The adjustment mechanism includes a support plate 28, a drive motor 29, a threaded rod 30, and an adjustment block 31. The support plate 28 is fixedly installed on the testing table 1 and has a moving groove 32. The threaded rod 30 is rotatably connected in the moving groove 32. The adjustment block 31 is threadedly connected to the threaded rod 30. The drive motor 29 is installed on the support plate 28, and the output end of the drive motor 29 is connected to the extension end of the threaded rod 30 that passes through the moving groove 32. The electric push rod 11 is installed on the adjustment block 31, and the output end of the electric push rod 11 is connected to a clamping member 12. The clamping member 12 clamps the testing head 13, and the testing head 13 is connected to an eddy current conductivity meter 14 via a transmission line.

[0038] The conductivity of the detection head 13 is measured by adjusting the detection head 13. The controller 36 controls the drive motor 29 to operate, which in turn drives the threaded rod 30 to rotate within the moving groove 32. The adjusting block 31 moves along the thread direction of the threaded rod 30, causing the electric push rod 11 to move horizontally. Simultaneously, the controller 36 controls the extension and retraction of the electric push rod 11 to adjust the vertical height of the detection head 13, ensuring that the detection head 13 is accurately aligned with the area to be tested on the aluminum alloy sample. After the position of the detection head 13 is adjusted, the eddy current conductivity meter 14 acquires the data collected by the detection head 13 through a transmission line. Using the eddy current method principle, the conductivity of the aluminum alloy sample is analyzed, and the measurement results are transmitted to the controller 36 for recording and processing.

[0039] Furthermore, a rubber pad 33 is provided at the lower end of the testing table 1, and mounting blocks 34 are fixedly provided at both ends of the testing table 1. The mounting blocks 34 are provided with mounting thread holes 35.

[0040] When fixing the test table 1, bolts are used to connect with the mounting threaded holes 35 to fix the test table 1. The rubber pads 33 can be used to buffer the impact during the test.

[0041] In the above embodiment, a controller 36 is installed on the detection table 1. The controller 36 is electrically connected to the electric push rod 11, the eddy current conductivity meter 14, the servo motor 15, the first servo electric cylinder 21, the second servo electric cylinder 26, and the drive motor 29.
