In practical applications, aluminum plates come in various sizes and specifications. Therefore, test fixtures need to be able to adapt to aluminum plates of different sizes to ensure the accuracy and reliability of the test. Thus, a tensile shear aluminum plate test fixture with an adjustable tensile range is needed.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a tensile shear aluminum plate testing fixture with an adjustable tensile range, comprising a base plate 1, a support frame 2 fixedly connected to the upper surface of the base plate 1, a motor 3 fixedly connected inside the support frame 2, a gear 4 fixedly installed at the output end of the motor 3, a rack 5 meshing with the tooth end of the gear 4, an L-shaped plate 6 fixedly connected inside the support frame 2, the outer wall of the rack 5 slidably connected to the outer wall of the L-shaped plate 6, a support block 7 fixedly connected to the outer wall of the rack 5, a limit block 8 fixedly connected inside the support frame 2, the inner wall of the support block 7 slidably connected to the outer wall of the limit block 8, the outer wall of the support block 7 slidably connected to the inner wall of the support frame 2, a placement block 9 fixedly connected to the upper surface of the support block 7, an L-shaped block 10 fixedly connected to the upper surface of the placement block 9, and an extrusion assembly provided inside the L-shaped block 10 for fixing the aluminum plate to be tested.
[0024] Specifically, motor 3 drives gear 4 to rotate, gear 4 drives rack 5 to slide in L-shaped plate 6, L-shaped plate 6 limits rack 5, rack 5 drives support block 7 to slide on limit block 8, limit block 8 limits the movement of support block 7, and support block 7 slides in support frame 2 while driving placement block 9 to move, thus achieving the effect of tensile testing on the clamped aluminum plate.
[0025] Reference Figure 1 The extrusion assembly includes a first hydraulic press 11, the outer wall of which is fixedly connected to the inside of the L-shaped block 10, and a pressure plate 12 is fixedly connected to the output end of the first hydraulic press 11.
[0026] Specifically, the placement block 9 serves to place the aluminum plate to be tested, and the first hydraulic press 11 drives the pressure plate 12 to clamp and fix the aluminum plate.
[0027] Reference Figure 1 and Figure 3 A support plate 13 and a limiting frame 21 are fixedly connected to the upper surface of the base plate 1. A fixing block 14 is fixedly connected to the outer wall of the support plate 13. A second hydraulic press 15 is fixedly connected inside the fixing block 14. A connecting block 16 is fixedly connected to the output end of the second hydraulic press 15. A limiting rod 17 is slidably connected to the outer wall of the connecting block 16. The outer wall of the limiting rod 17 is fixedly connected to the outer wall of the support plate 13. A connecting rod 18 is rotatably connected to the outer wall of the connecting rod 16. A shearing blade 19 is rotatably connected to the outer wall of the connecting rod 18. A U-shaped rod 20 is fixedly connected to the outer wall of the support plate 13. The shearing blade 19 is slidably connected to the outer wall of the U-shaped rod 20. The outer wall of the shearing blade 19 is slidably connected to the inside of the limiting frame 21. A pressure tester 22 is fixedly connected to the upper surface of the limiting frame 21.
[0028] Specifically, the second hydraulic press 15 pulls the connecting block 16 to slide on the limiting rod 17, and the limiting rod 17 limits the sliding of the connecting block 16. The connecting block 16, through the connecting rod 18, drives the shearing blade 19 to slide on the U-shaped rod 20, and the U-shaped rod 20 limits the shearing blade 19. This allows the U-shaped rod 20 to slide within the limiting frame 21. Simultaneously, under the action of the pressure tester 22, the shearing test of the aluminum plate is achieved.
[0029] Working principle: When this fixture is needed, the aluminum plate to be tested is first placed on the placement block 9. The first hydraulic press 11 is started, which drives the pressure plate 12 to clamp and fix the aluminum plate. The motor 3 drives the gear 4 to rotate, which in turn drives the rack 5 to slide in the L-shaped plate 6. The rack 5 drives the support block 7 to slide on the limit block 8. While the support block 7 slides in the support frame 2, it also drives the placement block 9 to move, thus allowing the clamped aluminum plate to be subjected to a tensile test. The second hydraulic press 15 pulls the connecting block 16 to slide on the limit rod 17. The connecting block 16 drives the shearing blade 19 on the U-shaped rod 2 via the connecting rod 18. The U-shaped rod 20 slides upwards, allowing it to slide within the limiting frame 21. Simultaneously, under the action of the pressure tester 22, a shear test can be performed on the aluminum plate. This fixture not only achieves the effect of tensile testing on aluminum plates of different sizes, but also eliminates the need for specialized testing equipment for each size, thereby reducing equipment replacement and debugging time. Testers can quickly adjust the fixture to adapt to different testing needs, improving the efficiency and continuity of the overall testing process. It also achieves the effect of shear testing on aluminum plates of different sizes, thereby reducing the frequency of equipment replacement and calibration, and correspondingly reducing maintenance and time costs.
