Method for controlling thickness of optical remote sensor space truss rod adhesive glue layer

Abstract

The invention provides a method for controlling thickness of an optical remote sensor space truss rod adhesive glue layer, and belongs to the field of space optical remote sensor space truss structure integration. The method comprises the following steps that adhesive glue internal annular surfaces of the two ends of a truss rod are configured and trimmed so that the size of internal diameter and cylindricity are enabled to meet the requirement of thickness of adhesive glue; an annular thin sheet is adhered at the bottom end of an adhesive cylinder, multiple equal-thickness short thin sheets are evenly adhered at the top end of the adhesive cylinder in a circumferential direction, and a truss rod connector and the truss rod are matched until the truss rod connector can smoothly rotate a circle at constant speed in the truss rod without waggling; an adhesive agent is uniformly coated on the adhesive glue internal annular surfaces of the truss rod, and the adhesive agent is uniformly coated on the external surface of the adhesive cylinder so that thickness of the adhesive agent of both parts is enabled to be greater than 2 / 3 of the required adhesive thickness; the adhesive cylinder is aligned with the adhesive glue internal annular surfaces of the truss rod, and the truss rod connector is slightly pushed and leftward and rightward rotated until the truss rod and the end surface of the truss rod connector are contacted; and the residual adhesive agent is removed so that adhesion is completed.

Description

technical field [0001] The invention belongs to the field of spatial optical remote sensor space truss structure integration, and in particular relates to a method for controlling the thickness of the bonding adhesive layer of the optical remote sensor space truss rods. Background technique [0002] At present, with the increasing demand for ground reconnaissance and mapping, the volume of space optical remote sensors is also increasing. In order to meet the increasingly urgent demand for lightweight, carbon fiber is widely used in aerospace work due to its high strength, high modulus and low density. Favored by researchers, the space truss structure with carbon fiber truss rods as the main load-bearing components has become the mainstream structure of large-volume space optical remote sensors. Therefore, the integration method of space truss structures has become a key technology. In order to meet the high reliability requirements of optical remote sensors, the thickness an...
