Problems solved by technology

In addition, the body cabin needs to be disassembled and assembled with other cabins many times. The disassembly process and the ground transportation process will easily lead to structural deformation. Comprehensive analysis, the installation accuracy of the cabin and electronic equipment is affected
[0003] Therefore, it is necessary to solve the problem of instability of the structural reference to ensure the stability of the structure and the assembly accuracy of electronic equipment.

Embodiment

[0045] figure 1 Shown is the cabin transfer reference position and the transfer reference block diagram of a preferred embodiment of the present invention, figure 2 Shown is a schematic diagram of the processing requirements of the cabin roof transfer datum buried block in the preferred embodiment of the present invention. Such as figure 1 and figure 2As shown, the cabin mechanical coordinate system of the preferred embodiment of the present invention establishes a benchmark, which can be measured by 4 φ30mm precision measurement embedded block front end faces and centerline positions on the front face of the cabin body and translated to the -X axis by δmm (δ =L-777) to determine the cabin mechanical coordinate system. The theoretical value of L is 779mm, and the measured value of L is used when the precise measurement benchmark is established. The actual measured value of L is the distance from the upper surface of the four φ30mm precise measurement buried blocks (ie, t...

Abstract

The invention relates to an establishing and measuring method of accuracy datum of a light honeycomb sandwich box type structure. Through the datum conversion, datum plane establishing, process datumand measuring platform establishing and like methods, the assembling accuracy of an electronic instrument on a structure platform is ensured. Through the datum research method, the stable datum establishing, datum prism mounting, and measurement platform researching, the assembling of the precision electronic instrument of an easily-deformed structure platform can be met, and an accuracy demand ofa cabin mechanical coordinate system can be met. The light honeycomb sandwich box type structure can be guaranteed to be located at a no-load condition, a full-load condition, and the process of connecting with other cabins, hoisting and transferring through the datum conversion method, the stable datum establishing, the datum prism mounting, and the measurement platform researching, the measurement datum is stable and free from deformation, and the measurement accuracy under various conditions can be met.

Description

technical field [0001] The invention relates to the establishment of a measurement reference, a measurement method and a process equipment for measurement, in particular to a light-weight honeycomb sandwich box structure easily deformable cabin reference conversion, a measurement method and a configuration of measurement process equipment. Background technique [0002] This lightweight honeycomb sandwich box structure is used in the docking cabin, which is the main component of the third-phase lunar orbiter. In order to meet the requirements of the detector configuration and weight reduction, the docking cabin adopts a lightweight honeycomb sandwich box structure. It consists of 4 triangular box structures and 1 square box structure. Docking cabin structure Each triangular box-shaped structure is composed of 2 side panels and 1 triangular top panel, and the square box-shaped structure is composed of 4 side panels and 1 square top panel. All the side panels are integrally so...
