Bonded insert mounting tensioner

Abstract

The invention belongs to an insert mounting technology and particularly relates to a bonded insert mounting tensioner. The bonded insert mounting tensioner comprises an insert, a mounting plate, a tensioning rod and a leaf spring, wherein the middle of the insert is provided with a threaded hole, the insert is bonded in a fastening hole of the mounting plate, the leaf spring is folded into a groove structure, the two bottom surfaces of the leaf spring are in contact with the bottom surface of the mounting plate, a clamping groove with two symmetrical clamping plates is formed in the middle of the groove structure, one end of the tensioning rod is connected with the insert in a screwed manner, the other end of the tensioning rod penetrates through the clamping groove of the leaf spring, and the tensioning rod is clamped and fixed by the clamping plates. The bonded insert mounting tensioner is simple in structure, convenient to mount, flexible in operation and stable and adjustable in tensioning force, can perform a stable tensioning function on the insert for a long time after the insert is mounted, impacts of human factors can be effectively eliminated, the effective connection and fixing of the bonded insert can be further realized, and the connecting strength of the insert is improved.

Description

technical field [0001] The invention belongs to the installation technology of inlaid parts, in particular to a tensioning device for bonding inlaid parts. Background technique [0002] Inserts are a kind of fasteners commonly used in aviation equipment, mainly composed of insert nuts and studs, such as figure 1 shown. When the inlay is connected to the metal structure, it is usually assembled by interference, such as figure 2 shown. However, with the application of a large number of high-performance composite materials in aviation equipment, the ability of composite materials to redistribute stress is poor. The traditional interference fit method may cause damage to the internal delamination of the composite material, so it is no longer suitable for the connection between the insert and the composite material. [0003] The adhesive connection between the insert and the composite material can effectively avoid the internal delamination damage of the composite material c...

AI Technical Summary

Problems solved by technology

However, after the insert is glued, the bonding between the insert nut and the fastening hole requires a certain constant tension to press the two for a certain period of time before they can be completely cured, otherwise the insert nut and the composite material may not be completely adhered to each other. reduce the strength of the connection

In the current installation process, manual or heavy objects are used to complete the bonding installation. Therefore, due to the influence of human factors and installation space factors, the nuts of the inlaid parts and the fastening holes are not fully bonded and bonded, which affects the connection strength of the inlaid parts.
