Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy composite material technology, and in particular to a positioning device for research on aluminum alloy composite materials. Background Technology
[0002] Aluminum alloy composite materials are industrial materials made by combining aluminum alloy with other materials. They are lightweight, high-strength, corrosion-resistant, and easy to process. When testing the mechanical properties of aluminum alloy rods, clamping is required to ensure that the aluminum alloy rods do not shift during the test and to guarantee the accuracy of the mechanical property test data.
[0003] For example, Chinese utility model patent application number CN202221900091.0 discloses a clamping device for studying the mechanical properties of aluminum alloys, comprising: a base, with a clamping assembly fixedly connected to the top of the base; the clamping assembly includes a lower clamping seat and an upper clamping seat, which are rotatably connected and have a positioning groove at the connection point, both ends of the positioning groove having chamfers, and the inner wall of the positioning groove being bonded with a rubber layer. This clamping device clamps an aluminum alloy rod using the lower and upper clamping seats, and utilizes an explosion-proof airbag to enhance the clamping stability of the aluminum alloy rod; the clamping position of the aluminum alloy rod varies depending on the mechanical properties being tested, allowing the device to be used for various mechanical property tests; the chamfers protect the clamping seats, preventing damage to the end of the positioning groove after the aluminum alloy rod bends, and also preventing extrusion marks on the bent section of the aluminum alloy rod, which would affect the acquisition of mechanical property test data.
[0004] The above solution has the following shortcomings in actual use: The solution uses airbags one and two to position and clamp the aluminum alloy rod. However, long-term inflation and deflation operations can easily lead to fatigue, aging or even damage of the airbag material, which in turn can cause gas leakage, resulting in uneven distribution of clamping force, thereby reducing the stability of positioning and affecting the accuracy of test data.

[0011] By adopting the above technical solution, the clamping component moves synchronously with the moving frame, enabling the clamping block to accurately push the sample to the center position, and the clamping pad provides a stable and non-destructive clamping force.
[0012] As a further description of the above technical solution: The second clamping assembly includes a second movable rod fixedly connected to one side of the inner wall of the movable frame.

[0014] As a further description of the above technical solution: The drive assembly includes a telescopic rod fixedly connected to one end of the rotating shaft, and a magnetic strip is fixedly connected to the telescopic end of the telescopic rod.
[0015] As a further description of the above technical solution: The magnetic strip is compatible with the magnetic sheet and its diameter is consistent with the diameter of the mounting groove.
[0016] As a further description of the above technical solution: The inner diameters of the limiting ring and the limiting frame are the same.
[0017] This utility model has the following beneficial effects: Compared with existing technologies, this positioning device for aluminum alloy composite material research, through the coordinated use of structures such as a limiting ring, limiting frame, mounting ring, adsorption assembly, threaded rod, bevel gear one, moving frame, clamping assembly one, clamping assembly two, rotating shaft, bevel gear two, and drive assembly, can achieve multi-point mechanical synchronous positioning and stable clamping of aluminum alloy composite materials.

[0021] Reference Figure 1-4 This utility model provides a positioning device for research on aluminum alloy composite materials: It includes a base 1, with two sets of support seats 21 fixedly connected to the top of the base 1. A limiting ring 3 and a limiting frame 4 are respectively fixedly connected to the top of the two sets of support seats 21. An installation ring 5 is fixedly connected to the back of the limiting frame 4. An adsorption component is provided on the surface of the installation ring 5. A hollow frame 20 is fixedly connected to the surface of the limiting frame 4. Threaded rods 6 are rotatably connected to the four sides of the inner wall of the hollow frame 20. A bevel gear 8 is fixedly connected to one end of the threaded rod 6. A movable frame 9 is threadedly connected to the outer surface of the threaded rod 6. Clamping component one and clamping component two are provided on one side of the inner wall of the limiting frame 4. A rotating shaft 10 is rotatably connected to one side of the inner wall of the limiting frame 4. A bevel gear 11 is sleeved on the outside of the rotating shaft 10. A drive component is provided at one end of the rotating shaft 10. The bevel gear 11 meshes with four bevel gears 8. The diameter of the limiting ring 3 and the inside of the limiting frame 4 are the same. Each set of support seats 21 consists of two support seats 21. One side of the moving frame 9 slides through to the outside of the limiting frame 4. Clamping component one is installed on the limiting frame 4, and clamping component two is installed on the limiting ring 3.
[0022] The adsorption assembly includes several mounting grooves 12 formed on the surface of the mounting ring 5. A magnetic suction plate 13 is fixedly connected to one side of the inner wall of the mounting groove 12. The several mounting grooves 12 are arranged in a circumferential array on the surface of the mounting ring 5. By adopting the above technical solution, the magnetic suction plate 13 generates a uniform radial adsorption force, which can stably adsorb and fix the driving assembly, effectively preventing it from shifting or loosening during operation, and improving the stability of the positioning device in the process of composite material research.
[0023] The clamping assembly includes a moving rod 14 fixedly connected to one side of the inner wall of the moving frame 9. One end of the moving rod 14 slides through the interior of the limiting frame 4 and is fixedly connected to a clamping block 15. A clamping pad 16 is fixedly connected to one side of the clamping block 15. By adopting the above technical solution, the clamping assembly moves synchronously with the moving frame 9, so that the clamping block 15 can accurately push the sample to the center position, and the clamping pad 16 provides a stable and non-destructive clamping force.
[0024] The second clamping component includes a second movable rod 17 fixedly connected to one side of the inner wall of the movable frame 9. One end of the second movable rod 17 slides through the inside of the limiting ring 3 and is fixedly connected to a second clamping block 18. A second clamping pad 19 is fixedly connected to one side of the second clamping block 18. By adopting the above technical solution, the second clamping component and the first clamping component can move synchronously, so that the second clamping block 18 can coordinate to center and clamp the sample from another direction, thus forming a stable multi-point clamping together with the first clamping component, ensuring the all-round stability of the sample during the test.
[0025] The drive assembly includes a telescopic rod 2 fixedly connected to one end of the rotating shaft 10. A magnetic strip 7 is fixedly connected to the telescopic end of the telescopic rod 2. The magnetic strip 7 is adapted to the magnetic plate 13 and its diameter is consistent with the diameter of the mounting groove 12. The telescopic end of the telescopic rod 2 slides through into the interior of the mounting ring 5.
[0026] Working principle: In use, the operator first places the aluminum alloy composite material to be tested horizontally between the limiting ring 3 and the limiting frame 4. Then, the operator pulls the magnetic strip 7 outward, causing the telescopic rod 2 to extend and detach from the magnetic plate 13, thereby releasing the fixation on the rotating shaft 10. Then, the operator rotates the magnetic plate 13, causing it to rotate the telescopic rod 2 and the rotating shaft 10, which in turn causes the bevel gear 11 on it to rotate synchronously. The bevel gear 11 drives the four meshing bevel gears 8. At this time, the four rotating bevel gears 8 precisely transmit the rotational motion to the four threaded rods 6, so that the moving frame 9, which is threadedly connected to the threaded rods 6, moves synchronously inward along the axial direction under the rotational drive. The movement causes the movable rod 14 and movable rod 17 fixed on it to move in coordination. The movable rod 14 pushes the clamping block 15 and clamping pad 16 of the clamping assembly 1 to move towards the sample side. At the same time, the movable rod 17 pushes the clamping block 18 and clamping pad 19 of the clamping assembly 2 to move closer to the sample until the clamping pad 1 and clamping pad 2 are in contact with the outside of the aluminum alloy composite material to be tested. At this time, the rotation of the magnetic strip 7 is stopped and pushed into the corresponding mounting groove 12, and fixed by magnetic adsorption 13. Thus, the clamping assembly 1 and clamping assembly 2 can clamp the aluminum alloy composite material to be tested from multiple directions, realizing the centering and stable clamping of the aluminum alloy composite material to be tested.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
