Glue filling clamp and glue filling method for stiffened wallboard compression test piece

Abstract

The invention discloses a glue filling clamp and a glue filling method for a stiffened wallboard compression test piece. The clamp structure comprises a stand column, a frame, a pressing assembly, a positioning assembly and a turnover assembly, the stand column is fixedly installed on the ground through an expansion foundation bolt after being leveled, the turnover assembly is arranged at the upper end of the stand column, a shaft support of the turnover assembly is fixedly connected with the frame, the positioning assemblies are transversely arranged on the upper and lower sides of the frame, and the pressing assemblies are longitudinally arranged on the left and right sides of the frame. The stiffened wallboard compression test piece is fixed and accurately positioned on the inner side of the glue filling clamp through the pressing assembly and the positioning assembly, and the stiffened wallboard compression test piece is subjected to turnover glue filling through the turnover assembly.

Description

technical field [0001] The invention belongs to the technical field of aviation bonding, and relates to a glue-filling fixture and a glue-filling method for a reinforced wall plate compression test piece. Background technique [0002] Reinforced panel structure is a common structure in the field of aviation manufacturing, and is widely used in important load-bearing parts of aircraft. In order to analyze the numerical value of the entire failure process of buckling, post-buckling and failure of the stiffened panel under compressive load, the design usually needs to be verified by the compressive stability test of its structure. In order to ensure that the test piece is evenly loaded and effectively prevent the ends from being crushed, metal corner boxes are set at both ends of the test piece and treated with potting resin. The design of potting often stipulates the relative position of the test piece body and the corner box, so special fixtures are required for the position...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional potting fixture only constrains the relative position of the aerodynamic surface of the test piece body, the cutting edge and the corner box, ignoring the relative position of the rib axis and the corner box, which has a more obvious impact on the results of the test buckling capacity;

[0004] 2. The distance between the two test loading ends of the traditional potting fixture cannot be adjusted and there is no compression device. The test piece is easy to shift during the potting process, and it is difficult to remove the test piece after the potting is completed;

[0005] 3. The traditional potting fixture needs to manually flip the test piece to complete the second corner box filling, which has great potential safety hazards
