[0002] The shortcomings of existing aluminum material strength detection equipment in detection accuracy mainly include equipment aging, inaccurate calibration, environmental factors, operation errors and equipment resolution limitations. Equipment aging can cause internal component wear or performance degradation, affecting the accuracy of test results. Inaccurate calibration is because the calibration parameters of the detection equipment may change during long-term use, and if calibration is not performed regularly, the detection data will deviate from the true value. Operation errors are usually caused by skill levels and experience differences of operators, and different personnel operating the same equipment may get different test results. Equipment resolution limitation refers to the design and manufacturing precision of the equipment itself limits the minimum change amount that can be detected, which is particularly evident when detecting high-precision aluminum materials.

The front side of each group of limit rails 120 is provided with a group of rear movable seats 220 for mutual engagement with them. The limit rails 120 can be used to keep the lower pressure seat 140 moving vertically up and down, and the rear limit seat 230 can be used to limit the maximum descending distance of the telescopic end of the electric cylinder 100.
[0025] A group of lower pressure seats 140 is provided on the front side of the two groups of rear moving seats 220 for driving the lower pressure seat 150 to move up and down. The rear side of the lower pressure seat 140 is fixed to the telescopic end of the electric cylinder 100 by bolts, and the lower pressure seat 150 can be driven to move up and down by using the lower pressure seat 140.
[0026] A group of front limit rods 130 for guiding the movement of the lower press seat 140 are provided inside the left and right ends of the front side of the lower press seat 140. The two groups of front limit rods 130 are connected and fixed to the inner side of the frame 110, and the lower press seat 140 can be guided and moved by using the front limit rods 130.
[0027] A set of support springs 160 for slowly releasing the downward pressure of the lower pressing seat 140 and supporting the lower pressing seat 140 is provided in the middle position of each set of front limit rods 130 . A set of carrier plates 170 for loading the aluminum material to be tested is provided at the lower ends of the two sets of support springs 160 .
[0028] A group of placement grooves 180 for placing the aluminum materials to be tested are provided on the inner side of the carrier plate 170, and a group of aluminum plates to be pressure tested are provided inside the placement grooves 180. The carrier plate 170 is a movable structure, and a group of load-bearing springs for supporting the downward pressure of the carrier plate 170 are also provided at the lower ends of the left and right sides of the carrier plate 170.
[0029] The compression limit height of the load-bearing spring is 40 mm less than the height of the pressure sensor 210. The load-bearing spring has the same structure as the support spring 160. A group of pressure sensors 210 for measuring the pressure borne by the aluminum plate are provided in the middle position of the lower end of the placement groove 180. A group of bases 190 for supporting the pressure sensor 210 are provided at the lower end of the pressure sensor 210.

[0030] See also Figures 1-4 As the first embodiment of the present invention: First, the staff cuts the aluminum material to be inspected into a rectangular block and places it inside the placement groove 180, then starts the electric cylinder 100, and drives its driving end to move downward, and makes the lower pressure seat 140 move along the two sets of limit rods for guidance, and drives the lower pressure seat 150 to move downward until the lower pressure seat 150 contacts the middle position of the upper end of the aluminum plate to be inspected, and then pushes the aluminum plate and the carrier plate 170 to move downward along the two sets of limit rods. The two sets of limit rods can effectively keep the lower pressure seat 140, the lower pressure seat 150 and the carrier plate 170 in the right position. It moves stably and accurately downward, thereby reducing repeated debugging of the equipment and ensuring multiple detection effects. When the carrier plate 170 moves downward, the two sets of load-bearing springs are squeezed to compress and support it. Since the compression limit height of the load-bearing spring is less than 40mm of the height of the pressure sensor 210, the load-bearing spring and the support spring 160 have the same structure. When the lower end of the aluminum plate to be detected contacts the pressure sensor 210, the electric cylinder 100 continues to apply force until the aluminum plate is deformed. The pressure sensor 210 at the lower end of the aluminum plate can effectively detect the real-time pressure of the aluminum plate (the reverse force of the two sets of load-bearing springs needs to be calculated and removed in advance).
[0031] See also Figures 1-4 , as the second embodiment of the present utility model: based on the description in the above embodiment, further, since the lower end of the base 190 is provided with two groups of bottom rails 200 for adjusting the front and rear position of the base 190, the lower end of the base 190 is provided with two groups of movable seats for movement, and the two groups of movable seats are movably engaged with the two groups of bottom rails 200. When the staff needs to detect the pressure level at different positions in the vertical direction of the aluminum plate, the front and rear position of the base 190 is adjusted by using the movable seat and the bottom rail 200, thereby adjusting the position of the pressure sensor 210.
[0032] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
