Description

Technical Field

[0001] The present application belongs to the technical field of aircraft ground strength test loading, and in particular relates to a pasting and positioning mold for an elastic medium and a metal connecting plate. Background Art

[0002] During ground-based verification tests of aircraft structural strength, loading blocks are attached to the surface of the test piece to apply bidirectional loads in tension and compression. Loading blocks are typically used for planar loading and typically consist of an elastic medium (mostly polyurethane or neoprene) and a metal connecting plate (mostly aluminum), bonded together with an adhesive.

[0003] Currently, when pasting elastic media and metal connecting plates, positioning is usually done manually, so there are problems such as inaccurate positioning, resulting in the elastic medium and metal connecting plate pasting failing to meet the error requirements. In addition, after pasting, external force needs to be applied to the two to make the metal connecting plate and the elastic medium surface adhesive; when the external force is applied, due to the presence of the glue, the metal connecting plate and the elastic medium surface may slip, causing the installation error to increase further. When applying external loads, heavy objects such as lead blocks are usually used for ballast. Due to the uneven surface of the heavy object, there is an uneven distribution of ballast, resulting in uneven force on the pasting surface, affecting the pasting performance, and thus having an adverse effect on the test safety and accurate loading.

[0004] Therefore, it is desired to have a technical solution to overcome or at least alleviate at least one of the above-mentioned deficiencies of the prior art. Summary of the Invention

In a preferred embodiment of the present application, the elastic medium block 4 is rectangular, and the slide groove on the fixed bottom plate 5 is cross-shaped, with four slide groove sections. The lateral fixing seat 6 and the lateral limiting top plate 8 each include four, which can achieve the limitation of the four-directional position of the elastic medium block 4 and the metal connecting plate 3. It can be understood that the structure of the present application is not limited to the above embodiment, and the structure of the base can be designed according to the specific structural form of the elastic medium block 4 and the metal connecting plate 3.
