Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, and in particular to a testing device for aircraft bracket processing. Background Technology
[0002] Aircraft brackets, as a crucial component of aircraft structures, are typically used to connect and support critical parts such as the fuselage, wings, and engines. These brackets are mostly columnar structures, characterized by high strength, rigidity, and light weight, and subject to stringent requirements for dimensional accuracy and structural stability. To ensure the assembly quality and safe use of aircraft brackets, comprehensive testing of their dimensions, shape, and surface quality is necessary during manufacturing. Manufacturing testing equipment, by inspecting finished or semi-finished brackets, can effectively assess manufacturing quality and prevent dimensional deviations or structural defects from affecting subsequent assembly and use.
[0003] Existing testing devices for aircraft bracket processing generally combine measuring components with a fixing structure to clamp and position the bracket, thereby detecting key dimensions and geometric parameters. These devices are mostly equipped with mechanical clamping structures and allow for manual or electric fixing and adjustment of the bracket, suitable for testing conventional columnar brackets. However, existing technologies often employ fixed-size or minimally adjustable fixing mechanisms. When dealing with columnar brackets of different diameters, this frequently requires changing clamps or manual adjustments, resulting in cumbersome operations. Furthermore, assembly deviations during clamping can easily lead to bracket displacement or loosening, affecting test accuracy. Therefore, this paper proposes a testing device for aircraft bracket processing to address these issues. Utility Model Content

[0030] Reference Figures 1-3This utility model provides an embodiment of a testing device for aircraft bracket processing, comprising a base 1, a fixing mechanism on the top of the base 1 for stably positioning the test workpiece to ensure stability and accuracy during testing, an adjustment mechanism inside the base 1 for adjusting the distance between the fixing mechanisms, a support frame 17 fixedly connected to the top of the base 1, a hydraulic rod 18 fixedly connected inside the support frame 17, and an impact block 19 fixedly connected to the output end of the hydraulic rod 18. The impact block 19 is used to simulate mechanical impact during actual use, thereby testing the impact resistance of the bracket; the fixing mechanism includes a rotating ring 3 and a clamping arm 9, a fixing ring 2 on the top of the base 1, and a rotating ring 3 rotatably connected to the side wall of the fixing ring 2, providing a certain rotational adjustment capability. It facilitates flexible adjustment of the clamping angle. A rotating block 4 is rotatably connected to the side wall of the fixed ring 2. A motor 5 is fixedly connected inside the rotating block 4. A screw 6 is fixedly connected to the output end of the motor 5. A moving block 7 is threadedly connected to the side wall of the screw 6. The moving block 7 is rotatably connected to the side wall of the rotating ring 3. The screw 6 is used to convert the rotational motion into linear motion to realize the position adjustment of the moving block 7. A rotating frame 8 is rotatably connected inside the rotating ring 3. The clamping arm 9 is slidably connected inside the rotating frame 8. The clamping arm 9 is rotatably connected to the side wall of the fixed ring 2. The rotating frame 8 is used to accommodate and guide the sliding of the clamping arm 9, improving the smoothness of the clamping process. A limiting ball 10 is fixedly connected inside the clamping arm 9. The limiting ball 10 is made of flexible material, which can effectively avoid damage to the workpiece surface during the clamping process and improve the protection performance of the device for the workpiece.
[0031] Reference Figure 1 and Figure 4 The adjustment mechanism includes a gear 14 and a rack 16. A fixed base 12 is fixedly connected to the bottom of the inner cavity of the base 1, serving as the mounting base for the adjustment mechanism. A motor 13 is fixedly connected to the top of the fixed base 12. The gear 14 is fixedly connected to the output end of the motor 13. A limit plate 15 is fixedly connected inside the base 1. The side wall of the rack 16 is slidably connected inside the limit plate 15. The limit plate 15 guides and restricts the movement direction of the rack 16, preventing it from deviating or jamming. The rack 16 meshes with the gear 14. When the gear 14 rotates, it can drive the rack 16 to move linearly. The base 1 has a groove inside, and a slider 11 is set inside the base 1. The side wall of the slider 11 is slidably connected to the inside of the groove. One side of the slider 11 is fixedly connected to the top of the rack 16. The slider 11 is centrally symmetrically arranged to ensure the balance and uniform force of the fixing ring 2 during the adjustment process, effectively improving the stability of the overall structure. The side wall of the fixing ring 2 is fixedly connected to the top of the slider 11, which facilitates the device to clamp brackets of different specifications. The fixing ring 2 is slidably connected to the top of the base 1 through the slider 11. The impact block 19 is located at the top of the central axis of the fixing ring 2, thereby improving the accuracy and repeatability of the impact test.
[0032] Working principle: When using this equipment, the columnar support is placed inside the rotating ring 3. Then, the starting motor 5 drives the screw 6 to rotate, causing the moving block 7 to move. When the moving block 7 moves, the rotating ring 3 deflects on the side wall of the fixed ring 2, thereby driving the rotating frame 8 to move. When the rotating frame 8 moves, it drives the clamping arm 9 to move, causing it to rotate on the fixed ring 2, thereby clamping and fixing the support to ensure stability during testing. After the support is fixed, the hydraulic rod 18 is started to drive the impact block 19 to move, causing it to impact the support to carry out the test. By observing the structural condition of the support after the impact, the test structure can be determined.
[0033] Before testing, the motor 13 can be started to drive the gear 14 to rotate, which in turn drives the racks 16 on both sides to move relative to each other along the limiting plate 15, thereby driving the slider 11 to move. When the slider 11 moves relative to each other, it will further drive the fixing ring 2 to move, changing the distance between the fixing rings 2 to fix the brackets of different specifications and improve the flexibility of the equipment.
[0034] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
