Standard sample bonding tool

Abstract

The invention discloses a standard sample bonding tool. The standard sample bonding tool comprises a mechanical test block, a platform, two guide columns, three positioning blocks and a pressing block, wherein the mechanical test block is arranged on the platform, and the two guide columns are vertically arranged on the two sides of the mechanical test block, the three positioning blocks are horizontally arranged on the two guide columns and can slide up and down along the guide columns, and the pressing block is arranged at the top of the mechanical test block. The standard sample bonding tool has the advantages that the bonding precision is high, the repeatability is good, the structure is simple, the operation is convenient, the adhesion force can be adjusted, and the bonding efficiencyis high.

Description

technical field [0001] The invention relates to the technical field of composite material manufacturing technology, in particular to a standard sample bonding tool. Background technique [0002] The composite honeycomb sandwich structure needs to be tested for mechanical properties, and the test pieces are prepared and tested according to ASTM C297. This standard requires high-precision bonding of honeycomb sandwich structures and aluminum alloys. [0003] My existing standard specimens are bonded by hand and then clamped with bow clamps. Since the adhesive needs a certain amount of time to solidify, the force of the workpiece during the clamping process is prone to misalignment of the bonding sample, resulting in poor bonding accuracy, which cannot meet the accuracy requirements of ASTM C297. The method of rough bonding first and then finishing the shape can ensure the final dimensional accuracy, but the secondary mechanical stress on the bonded parts will destroy the mec...

AI Technical Summary

Problems solved by technology

Since the adhesive needs a certain amount of time to solidify, the force of the workpiece during the clamping process is prone to dislocation of the bonding sample, resulting in poor bonding accuracy, which cannot meet the accuracy requirements of ASTM C297

However, the method of rough bonding first and then finishing the shape can ensure the final dimensional accuracy, but the secondary mechanical stress on the bonded parts will destroy the mechanical properties of the original bonded structure and affect the final test results.
