To improve reliability, the waste of raw material and space flight resource is caused, optical sensor reliability is low.In order to solve above-mentioned technology
Difficult point, improves reliability, while the waste of raw material and space flight resource is avoided, in the urgent need to related art method ensures to meet viscous
The homogeneity of adhesive thickness is controlled while connecing thickness, in addition, technique means should it is simple, conveniently, it is feasible.
The content of the invention
It is an object of the invention to propose a kind of structure for controlling optical sensor space truss bar bonding bondline thickness and
Method, the problem of solving the glue line thickness and inconsistent thickness evenness that prior art is present, and raw material and space flight
The waste of resource, the problem of optical sensor reliability is low.Complete space optical remote sensor space truss structure unstressed integrated
Work, to meet the adhesive strength needs of carbon fiber truss rod.
To achieve the above object, the method that a kind of control optical sensor space truss bar of the invention is bonded bondline thickness
Comprise the following steps：
Step one：With truss rod two ends viscose glue inner ring surface is repaiied, its internal diameter size and cylindricity is set to meet viscose glue thickness requirement；
Step 2：Annular wafer is pasted in the bottom of bonding cylinder, is uniformly pasted in the top circumferencial direction of bonding cylinder
The short thin slice of multi-disc uniform thickness, truss knock-off joint and truss rod trial at the uniform velocity smooth in truss rod can be turned with truss knock-off joint
It is dynamic one week, and without untill rocking；
Step 3：Bonding agent uniformly is coated on truss rod viscose glue inner ring surface, it is uniform on bonding cylindrical outer surface
The thickness for coating the bonding agent on bonding agent, truss rod viscose glue inner ring surface and the bonding agent on bonding cylindrical outer surface is all higher than institute
Need the 2/3 of adhesive thickness；
Step 4：Bonding cylinder is directed at truss rod viscose glue inner ring surface, gently pushed and left-right rotation truss knock-off joint, directly
Untill truss rod and truss rod joint end contact；
Step 5：Redundant adhesive is removed, bonding is completed.
The annular wafer is equal with the actually required adhesive thickness of glue-line, the thickness of the short thin slice and the thickness of annular wafer
Degree is equal.
The width sum of the short thin slice of the multi-disc uniform thickness is less than the 1/3 of bonding cylinder girth.
There is chamfering on the top of the bonding cylinder, and truss rod two ends inner ring surface has chamfering.
The present invention operation principle be：A kind of control optical sensor space truss bar bonding bondline thickness of the present invention
Method is uniformly staggeredly pasted on the short thin slice of multi-disc uniform thickness of bonding cylindrical tip in flap form and is pasted on annular form viscous
The uniform thickness annular wafer for connecing cylinder bottom constitutes the equal narrow ring of two external diameters, after truss knock-off joint and truss rod assembling,
The cavity that thickness uniformity is formed in the middle part of cylinder is bonded as glue injection cavities, this ensure that being glued the uniformity of bondline thickness；
By annular wafer takes thickness to be glued consistency of thickness with theoretical, the accuracy for being glued bondline thickness in turn ensure that；Simultaneously as
The bonding short thin slice of cylindrical tip is arranged to flap, bonding cylinder and truss rod viscose glue inner ring surface all gluings, is pushed away in truss knock-off joint
During sending, the bonding agent on truss rod viscose glue inner ring surface has 2/3 and enters glue injection cavities above by flap gap, is forming chamber
While interior malleation, the initial gluing defect of viscose glue inner ring surface is filled up, after assembling is finished, the stable glue injection cavities shape of thickness and position
Into, bonding agent is in the presence of positive intraluminal pressure, uniformly full of glue injection cavities, and the bonding agent being more than is overflowed by flap gap, from
And the bonding quality of bonding agent is ensure that, and effectively eliminate the internal stress of bonding agent.
Beneficial effects of the present invention are：A kind of control optical sensor space truss bar bonding bondline thickness of the present invention
Method, can be in accurate control bonding bondline thickness when progress space truss bar is glued integrated, and ensure that bondline thickness
While uniformity requirements, bonding agent is set fully to be full of glue injection cavities, it is ensured that adhesive strength demand, and it is steady effectively to improve structure
Qualitative and reliability, reduction is developed and launch cost；In addition, this method is simple, convenient, without residual stress is bonded, it is integrated
Process can be carried out successively, can effectively shorten the lead time.The present invention unstressed is debug available for the accurate of space truss structure
Field.
