Technical Field

[0001] This utility model relates to the field of strength testing technology, specifically an aluminum alloy strength testing device. Background Technology

[0002] In the processing of aluminum alloy sheets, in order to determine whether they have sufficient strength to meet specific usage requirements and thus ensure that the products do not experience quality problems such as breakage or deformation during use, a strength testing device is required.

[0003] A Chinese patent with announcement number CN218121611U discloses an aluminum alloy strength testing device, including a drive component a and a drive component b. The drive component a is provided with a support mechanism a, and the drive component b is provided with a support mechanism b. The support mechanism a is connected to a testing mechanism through a connector. This invention supports the aluminum alloy product by moving the support mechanism b through the drive component b, and completes the strength testing of different positions of the aluminum alloy product through the drive component a, the support mechanism a, and the testing mechanism, effectively improving the testing efficiency of the prior art.

[0004] However, the above-mentioned testing device still has some problems. In practical applications, since there is no replacement component that can replace impact blocks with different contact areas, it is impossible to comprehensively and accurately evaluate the strength performance of aluminum alloy under different stress area conditions, which leads to misjudgment of the strength of aluminum alloy and thus affects the reliability of the product in practical applications. Therefore, an aluminum alloy strength testing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes an aluminum alloy strength testing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An aluminum alloy strength testing device of this utility model includes a workbench, a rotating assembly mounted on top of the workbench, and a mounting frame. A scale is mounted on one side of the mounting frame, and a rotating shaft is rotatably mounted between the two sides of the mounting frame. One end of the rotating shaft passes through the center of the scale and is fixedly connected to an indicator needle. Four connecting rods are equidistantly mounted on the outer wall of the rotating shaft inside the mounting frame. An impact block is fixedly connected to one end of each connecting rod. The impact blocks have the same mass but different contact areas. A gear is fixedly connected to the other end of the rotating shaft. A slide rail is provided on the other side of the mounting frame, and a slide bar is slidably mounted inside the slide rail. A rack is fixedly connected to one side of the slide bar. A telescopic rod is mounted on one side of the mounting frame, and a connecting plate is mounted on the working end of the telescopic rod. A support rod is mounted on one side of the rack, and one end of the support rod is fixedly connected to one side of the connecting plate. This allows for convenient replacement of impact blocks with different contact areas to test aluminum alloys, thereby more comprehensively evaluating the strength performance of aluminum alloys under different contact conditions.

[0007] Preferably, an L-shaped frame is installed at the top edge of the workbench, and a cylinder is installed on the top side of the L-shaped frame. The mounting bracket is installed on the bottom side of the working end of the cylinder, which facilitates driving the mounting bracket to move up and down, thereby controlling the impact force of the impact block on the aluminum alloy and improving the flexibility and accuracy of the test.

[0008] Preferably, the workbench has an internal cavity. A servo motor is installed on one side of the cavity, and a gear is installed at the output end of the servo motor. Two guide rods are symmetrically fixed between the two sides of the cavity. A rack is installed on the outer wall of each guide rod, and the racks are symmetrically arranged around a central axis. Each rack meshes with a gear. A movable plate is fixed to the outer side of each rack. Two sliding grooves are symmetrically formed inside the top side of the workbench. A slider is fixed to the top side of the movable plate and slides inside the sliding grooves, thereby achieving stable clamping of aluminum alloy plates of different sizes and improving the applicability and stability of the inspection.

[0009] Preferably, a fixing plate is fixedly connected to the top side of the slider, a threaded rod is rotatably installed inside the fixing plate, a pressure block is installed on the bottom side of the threaded rod, and a handle is installed at the top of the threaded rod, so as to firmly fix the aluminum alloy plate to the worktable and ensure the stability and accuracy of the detection process.

[0010] Preferably, a pressure sensor is installed at the center of the top side of the workbench. The pressure sensor is used to monitor the pressure of the impact block on the test piece and can monitor the impact pressure of the impact block on the aluminum alloy sheet in real time.

[0011] Preferably, a control panel is installed on one side of the workbench. The control panel is electrically connected to the pressure sensor and the cylinder, and is used for signal transmission of the pressure sensor and operation control of the cylinder, making the entire detection process more convenient and efficient, and improving detection efficiency.

[0012] The advantages of this utility model are:

[0013] 1. The present invention activates the telescopic rod, which drives the connecting plate to move. This causes the support rod to pull or push the rack. The rack slides in the slide rail through the slide bar, which drives the gear to rotate, causing the rotating shaft to rotate. This, in turn, drives the connecting rod and the impact block to rotate. The rotation angle can be accurately observed and controlled through the dial and indicator needle. This allows for easy replacement of impact blocks with different contact areas to test aluminum alloys, thereby providing a more comprehensive evaluation of the strength performance of aluminum alloys under different contact conditions.

[0014] 2. The servo motor of this utility model drives the gear two to rotate, which causes the two racks two to move simultaneously towards the center or outward along the guide rod. The movement of the racks two drives the movable plate to move, and the slider on the top of the movable plate slides in the slide groove, thereby moving the fixed plate on the top of the slider. The position of the two fixed plates is adjusted to adapt to the size of the aluminum alloy plate, ensuring the stability and accuracy of the detection process. Attached Figure Description

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-4As shown, an aluminum alloy strength testing device includes a workbench 1. A rotating assembly is mounted on top of the workbench 1. The rotating assembly includes a mounting frame 2. A scale 3 is mounted on one side of the mounting frame 2. A rotating shaft 4 is rotatably mounted between the two sides of the mounting frame 2. One end of the rotating shaft 4 passes through the center of the scale 3 and is fixedly connected to an indicator needle 5. Four connecting rods 6 are equidistantly mounted on the outer wall of the rotating shaft 4 inside the mounting frame 2. One end of each connecting rod 6 is fixedly connected to an impact block 7. The impact blocks 7 have the same mass but different contact areas. A gear 8 is fixedly connected to the other end of the rotating shaft 4. A slide rail 9 is provided on the other side of the mounting frame 2. A slide bar 10 is slidably mounted inside the slide rail 9. A rack 11 is fixedly connected to one side of the slide bar 10. A telescopic rod 12 is mounted on one side of the mounting frame 2. A connecting plate 13 is mounted on the working end of the telescopic rod 12. A support rod 14 is mounted on one side of the rack 11. The impact block 7 is fixed to one side of the connecting plate 13. During operation, in practical applications, due to the lack of a replacement assembly that can replace impact blocks 7 with different contact areas, it is impossible to comprehensively and accurately evaluate the strength performance of aluminum alloy under different stress area conditions, leading to misjudgment of the strength of aluminum alloy and thus affecting the reliability of the product in practical applications. When it is necessary to replace impact blocks 7 with different contact areas, the telescopic rod 12 is activated. The extension and retraction of the telescopic rod 12 causes the connecting plate 13 to move, which causes the support rod 14 to pull or push the rack 11. The rack 11 slides in the slide rail 9 through the slide bar 10. The movement of the rack 11 will drive the gear 8 to rotate. The rotation of the gear 8 will cause the rotating shaft 4 to rotate, thereby driving the connecting rod 6 and the impact block 7 to rotate. The rotation angle can be accurately observed and controlled through the dial 3 and the indicator needle 5 to select the required impact block 7. This makes it easy to replace impact blocks 7 with different contact areas to test aluminum alloy, thereby more comprehensively evaluating the strength performance of aluminum alloy under different contact conditions.

[0024] Please see Figure 1 , 2 As shown in Figure 5, the workbench 1 has an internal cavity 17. A servo motor 18 is installed on one side of the cavity 17. A gear 19 is installed at the output end of the servo motor 18. Two guide rods 20 are symmetrically fixed between the two sides of the cavity 17. A rack 21 is installed on the outer wall of each guide rod 20. A movable plate 22 is fixed to the outer side of each rack 21. Two sliding grooves 23 are symmetrically opened inside the top side of the workbench 1. A slider 24 is fixed to the top side of the movable plate 22. The slider 24 is slidably installed inside the sliding groove 23. A fixed plate 25 is fixed to the top side of the slider 24. A threaded rod 26 is rotatably installed inside the fixed plate 25. A pressure block 27 is installed on the bottom side of the threaded rod 26. A handle 28 is installed on the top end of the threaded rod 26.

[0025] A pressure sensor 29 is mounted at the center of the top side of the workbench 1. The pressure sensor 29 is used to monitor the pressure of the impact block 7 on the test piece. An L-shaped frame 15 is installed at the top edge of the workbench 1, and a cylinder 16 is installed on the top side of the L-shaped frame 15. The mounting bracket 2 is installed on the bottom side of the working end of the cylinder 16. A control panel 30 is installed on one side of the workbench 1. During operation, in the processing of aluminum alloy sheets, in order to determine whether they have sufficient strength to meet specific usage requirements and thus ensure that the product will not have quality problems such as breakage or deformation during use, a strength testing device is required. The aluminum alloy sheet is placed on the top side of the workbench 1, and the servo motor 18 is started, which drives the gear 19 to rotate. This causes the two racks 21 to move simultaneously towards the center or outward along the guide rod 20. The movement of the racks 21 drives the movable plate 22 to move. The slider 24 on the top of the movable plate 22 slides in the groove 23, thereby moving the fixed plate 25 on the top of the slider 24. The positions of the two fixed plates 25 are adjusted to fit the size of the aluminum alloy sheet. Then, the handle 28 is turned to drive the threaded rod 26 to rotate, causing the pressure block 27 to move downward and fix the aluminum alloy sheet on the workbench 1, ensuring stability and accuracy during the testing process. When preparing for strength testing, the cylinder 16 on the top of the L-shaped frame 15 is activated, and its working end pushes the mounting frame 2 downward, bringing the impact block 7 close to the aluminum alloy sheet to be tested. When the impact block 7 contacts the aluminum alloy sheet and applies pressure, the pressure sensor 29 monitors the pressure of the impact block 7 on the aluminum alloy sheet in real time and transmits the pressure signal to the control panel 30. When a certain pressure level is reached, the control panel 30 will close the cylinder 16. The pressure sensor 29 is model PA1140.

[0026] Working principle: The aluminum alloy sheet is placed on the top side of the workbench 1. The servo motor 18 is started, which drives the gear 19 to rotate. This causes the two racks 21 to move simultaneously towards the center or outward along the guide rod 20. The movement of the racks 21 drives the movable plate 22 to move. The slider 24 on the top of the movable plate 22 slides in the groove 23, thereby moving the fixed plate 25 on the top of the slider 24. The position of the two fixed plates 25 is adjusted to fit the size of the aluminum alloy sheet. Then, the handle 28 is turned, which drives the threaded rod 26 to rotate, causing the pressure block 27 to move downward and fix the aluminum alloy sheet on the workbench 1, ensuring the stability and accuracy of the testing process. When the strength test is about to be performed, the cylinder 16 on the top of the L-shaped frame 15 is activated. Its working end pushes the mounting frame 2 downward, causing the impact block 7 to approach the aluminum alloy sheet to be tested. When the impact block 7 contacts the aluminum alloy sheet and applies pressure, the pressure sensor 29 monitors the pressure of the impact block 7 on the aluminum alloy sheet in real time and transmits the pressure signal to the control panel 30. When a certain pressure level is reached, the control panel 30 will close the cylinder 16.

[0027] When it is necessary to replace the impact block 7 with one of different contact areas, the telescopic rod 12 is activated. The extension and retraction of the telescopic rod 12 causes the connecting plate 13 to move, which in turn causes the support rod 14 to pull or push the rack 11. The rack 11 slides in the slide rail 9 through the slide bar 10. The movement of the rack 11 will drive the gear 8 to rotate. The rotation of the gear 8 will cause the rotating shaft 4 to rotate, thereby driving the connecting rod 6 and the impact block 7 to rotate. The rotation angle can be accurately observed and controlled through the dial 3 and the indicator needle 5 to select the required impact block 7. This allows for easy replacement of impact blocks 7 with different contact areas to test aluminum alloys, thereby more comprehensively evaluating the strength performance of aluminum alloys under different contact conditions.
