Technical Field

[0001] This utility model relates to a vibration fixture, specifically a three-dimensional vibration fixture for a self-locking nut assembly of a floating support plate. Background Technology

[0002] Self-locking nut assemblies for movable pallets are commonly used in aerospace equipment, such as the assembly of aircraft wings and fuselages, as well as the connection of rocket stages and satellite components. To ensure the proper connection performance of these assemblies, vibration testing is necessary. Vibration testing is a common method for testing fastener performance. Conventional vibration testing methods refer to GJB715.3A-2011, which involves installing the self-locking nut in a tooling fixture and conducting a vertical vibration test. However, this method only tests the overall performance of the self-locking nut after bolt installation and cannot test the movable performance of the self-locking nut itself. Furthermore, it suffers from difficulties in installation, inconvenient testing, and potential product damage. Utility Model Content

Detailed Implementation

[0025] The present invention will be further described below with reference to some specific embodiments.

[0026] Example 1

[0027] See Figure 1-9 A three-dimensional vibration fixture for a floating pallet self-locking nut assembly includes a vibration table 6, which is an existing vertical vibration test bench. A vibration base 1 is mounted on the vibration table 6, and a vibration riveting plate 2 is mounted on the vibration base 1. The vibration riveting plate 2 is used to fix the floating pallet self-locking nut assembly 3. (See also...) Figure 3 The movable pallet self-locking nut assembly 3 is an existing fastening part, including a movable pallet 301, a bracket 302, a self-locking nut 303, and a riveting hole 304. The movable pallet 301 and the bracket 302 are used to limit the position of the self-locking nut 303. The riveting hole 304 is used to firmly rivet the movable self-locking nut assembly 3 to a specific structural component or part. The movable pallet self-locking nut assembly 3 is placed on a vibration table 6 using the vibration fixture of this utility model for vibration testing to detect whether the movable pallet self-locking nut assembly 3 falls off, deforms, or is damaged during the movement of the self-locking nut 303.

[0028] Furthermore, the vibration base 1 is formed by several mounting columns 101 into a frame structure, with one mounting column mounted on the vibration table 6, and vibration riveting plates 2 mounted on one or more other mounting columns. The vibration base 1 of this invention includes multiple mounting columns 101, facilitating the installation of multiple vibration riveting plates 2 in multiple directions, enabling multi-directional vibration tests and improving test efficiency.

[0029] Furthermore, the vibration base 1 is formed by four mounting columns 101 to form a square frame structure, which facilitates the installation and removal of the vibration base 1 on the vibration table 6, and also facilitates the installation and removal of the vibration riveting plate 2 on the vibration base 1.

[0030] Furthermore, multiple fixing holes 102 are opened on the four mounting columns 101, and multiple positioning nuts 7 are set on the vibration table 6. The positioning bolt 8 passes through the fixing hole 102 on one of the mounting columns to fix the vibration base 1 in the positioning nut 7. The vibration riveting plate 2 is set on another or several mounting columns through the fixing hole 102.

[0031] Furthermore, multiple fixing holes 201 and 202 are provided on the vibrating riveting plate 2. The rivet passes through the mounting hole 304 and fixing hole 201 on the moving support plate self-locking nut assembly 3 to fix the moving support plate self-locking nut assembly 3 to the vibrating riveting plate 2. The fastening bolt 4 passes through fixing hole 102 and fixing hole 202, and the end is fixed by fastening nut 5. The vibrating riveting plate 2 is fixed to the vibrating base 1 by the cooperation of fastening bolt 4 and fastening nut 5.

[0032] Furthermore, the vibration riveting plate 2 is a square plate, which reduces the space occupied and increases the arrangement area of ​​the self-locking nut assembly 3 of the floating support plate.

[0033] Furthermore, four fixing holes 202 are provided, and the four fixing holes 202 are located at the center of the vibration riveting plate 2. The central axis of the four fixing holes 202 is distributed in a circle, which facilitates fixing the vibration riveting plate 2 in different directions on the vibration base 1.

[0034] The method of using this utility model of a three-dimensional vibration fixture with a self-locking nut assembly for a movable support plate is as follows: Rivet the self-locking nut assembly for the movable support plate to the vibration riveting plate, then install the vibration riveting plate on the vibration base, and finally install the vibration base onto the vibration table (e.g., Figure 6 and Figure 7 This allows for the X-axis vibration test of the self-locking nut of the floating pallet;

[0035] After completing the X-axis test, rotate the vibration riveting plate 90° and install it onto the vibration base (e.g., Figure 8 This completes the Y-axis vibration test of the self-locking nut of the floating support plate;

[0036] After completing the Y-axis test, rotate the vibration base 90° and install it onto the vibration table (e.g., Figure 9 This allows for the completion of the Z-axis vibration test of the self-locking nut of the quick-release sliding plate.

[0037] In addition, other operating methods that can achieve XYZ triaxial vibration testing are also possible. This utility model's riveted vibration plate can simultaneously install various specifications of movable support plate self-locking nut assemblies for testing, depending on the number of test products. Furthermore, two or three vibration riveted plates can be simultaneously installed on the vibration base for testing. See [link / reference]. Figure 10 This greatly improves the efficiency of the experiment.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
