[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] like Figures 1-4 As shown, this embodiment provides an aluminum frame yield strength testing device, including a base 1 and a test assembly located at one end of the top of the base 1. A guide rail 2 is fixed to the top of the base 1 along the length direction, and the guide rails 2 are symmetrically fixed on both sides of the top of the base 1. A carrier plate 3 is slidingly provided between the tops of the two sets of guide rails 2. A translation mechanism for controlling the movement of the carrier plate 3 is provided on the top of the base 1. Support blocks 4 are symmetrically fixed on both sides of the top of the carrier plate 3, and positioning mechanisms 5 are provided at both ends of the top of the support block 4.

[0025] Overall working principle: Before testing, the carrier plate 3 is moved to one end away from the test assembly using a translation mechanism to prevent the test assembly from affecting the placement of the frame. The frame is then placed on the support block 4 on top of the carrier plate 3, and the positioning mechanism 5 is used to fix the frame on the support block 4. The fixed frame is then moved to the bottom of the test assembly using a translation mechanism to test the yield strength of the frame.

[0026] In this embodiment, the test assembly includes a gantry 6, a microcomputer 7, a hydraulic cylinder 8, a pressure sensor 9 and an extrusion block 10. The gantry 6 is fixed at one end of the top of the base 1, and the microcomputer 7 is installed on one side of the gantry 6. The hydraulic cylinder 8 is vertically installed on the inner top of the gantry 6, and the pressure sensor 9 is installed at the output end of the hydraulic cylinder 8. The extrusion block 10 is installed at the bottom of the pressure sensor 9.

[0027] Local working principle: During the test, the hydraulic cylinder 8 is started to control the downward movement of the extrusion block 10 to contact the frame, and the pressure sensor 9 is used to detect the extrusion force during the extrusion process, and the pressure value is recorded by the microcomputer 7 until the frame yields. At this time, the result measured by the pressure sensor 9 is the maximum force on the frame.

[0028] In this embodiment, the translation mechanism includes a slide groove 11, a slider 12 and a screw 13. The slide groove 11 is opened at the middle position of the top of the base 1 along the length direction of the base 1. The slider 12 is slidably installed inside the slide groove 11. The top of the slider 12 is fixedly connected to the carrier plate 3. A screw 13 is rotatably installed between the two ends of the slide groove 11, and the screw 13 and the slider 12 are threadedly connected.

[0029] Partial working principle: When controlling the movement of the carrier plate 3, the screw rod 13 is rotated to control the slider 12 to move inside the slide groove 11, thereby driving the horizontal sliding of the carrier plate 3.

[0030] In this embodiment, one end of the screw rod 13 extends to the outer end portion of the base 1 , and an adjusting disk 14 is installed at the end of the screw rod 13 located outside the base 1 .

[0031] Partial working principle: Through the setting of the adjustment disk 14, manual adjustment can be conveniently performed during use, making the operation more convenient.

[0032] In this embodiment, the positioning mechanism 5 includes a cross-shaped guide groove 15, a clamping block 16, a first spring 17, a slope 18 and an expansion component. The cross-shaped guide groove 15 is opened at the end of the support block 4, and the ends of the cross-shaped guide groove 15 are slidably installed with clamping blocks 16. A first spring 17 is provided between the clamping blocks 16 and the inner ends of the cross-shaped guide groove 15. Multiple groups of clamping blocks 16 are fitted together, and the inner sides of the bottom ends of the clamping blocks 16 are provided with slopes 18. An expansion component for opening the clamping blocks 16 is provided below the cross-shaped guide groove 15.

[0033] Partial working principle: The clamping blocks 16 are initially fitted together in a cylindrical shape. When the frame is placed, the clamping blocks 16 pass through the mounting holes at the ends of the frame. Then, the expansion assembly is used to expand multiple groups of clamping blocks 16 outward to squeeze and position the ends of the frame. After the processing is completed, the expansion state of the clamping blocks 16 is released, and the first spring 17 drives the clamping blocks 16 to return to their original position so that the frame can be taken out.

[0034] In this embodiment, the shape of the clamping block 16 is a quarter of a cylinder, and an inclined protrusion is provided on the top of the outer side of the clamping block 16 .

[0035] Partial working principle: When the clamping block 16 is expanded outward, the inclined protrusion on the clamping block 16 will provide downward pressure on the frame to ensure the stability of the frame.

[0036] In this embodiment, the expansion component includes a cylinder 19, a piston 20, a second spring 21, a push rod 22 and an air pump 23. The cylinder 19 is installed below the cross guide groove 15. The piston 20 is slidably installed inside the cylinder 19. The second spring 21 is installed between the bottom of the piston 20 and the inner bottom end of the cylinder 19. The top of the piston 20 is fixed with a push rod 22 extending to the inside of the cross guide groove 15, and the outer side of the push rod 22 is in contact with the inclined surface 18 at the bottom of the clamping block 16. The top of the carrier plate 3 is installed with an air pump 23, and the output end of the air pump 23 is connected to the bottom of the cylinder 19 through a conduit.

[0037] Local working principle: When controlling the expansion of the clamping block 16, start the air pump 23 to simultaneously introduce gas into the interior of multiple groups of cylinders 19. The pressure inside the cylinder 19 increases to control the upward movement of the piston 20. The push rod 22 is used to contact the inclined surface 18 at the bottom of the clamping block 16 to expand the clamping block 16 outward. After the processing is completed, turn off the air pump 23 and discharge the gas inside the cylinder 19. At this time, the second spring 21 will control the automatic reset of the piston 20.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
