A glue coating device for the inner cavity of a long rod of a satellite frame structure and its application method

Abstract

The invention discloses a satellite frame structure long rod part inner cavity gluing device. The satellite frame structure long rod part inner cavity gluing device comprises a base, a positioning scaleplate mounted on the base, a limiting stop dog, a gluing rod and a pressing plate. The positioning scaleplate is mounted on the upper top face of the base. The limiting stop dog is mounted on the upper top face of one side of the positioning scaleplate. The gluing rod is mounted on the other side of the positioning scaleplate. The front end of the gluing rod is provided with a gluing groove usedfor storing glue liquor. The rear end of the gluing rod and the pressing plate are coaxially mounted on a positioning column of the base, the gluing rod can be controlled to move downwards by pressing the pressing plate, and the effect that sponge at the front end of the gluing rod makes contain with an inner cavity of a rod part stably is ensured; and a pressurizing device is connected with thegluing rod through a pressurizing pipe. Operation quality of multiple links such as glue joint zone positioning, glue liquor storage, glue liquor feeding, glue liquor seepage and glue liquor brushingcan be improved, the gluing device is applicable to gluing operation of deep positions of the long rod part inner cavity, operation is convenient and reliable, and the long rod part inner cavity gluing quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a device for applying glue to the inner cavity of a long rod of a satellite frame structure and a method for using it. Background technique [0002] An important structural part in composite frame satellite products, it has the functions of bearing force and providing installation interface. For the sake of local reinforcement and installation interface considerations, a large number of embedded parts are usually installed in the rods of the frame structure, and the embedded parts are mainly connected to the rods through adhesives. The glue joint of embedded parts is mainly to pre-apply glue in the glue joint area of ​​the inner cavity of the rod and the glue joint area of ​​the embedded parts, and then push the embedded parts to the glue joint position. The problem with this method is that the glue on the surface of the embedded part will be scratched by the inner wall of the...

AI Technical Summary

Problems solved by technology

In the end, the amount of glue stored in the glued area is insufficient, and there is a lack of glue area, which affects the quality of the glued flaw detection

[0003] The current solution is to pre-coat glue in the bonding area of ​​the inner cavity to ensure that the amount of glue in the bonding area is sufficient, but there is no better method for pre-coating the inner cavity of long rods
