General assembly platform telescopic mechanism

Abstract

The invention provides a general assembly platform telescoping mechanism, and belongs to the field of spacecraft ground test. The mechanism comprises a telescoping assembly and a turnover assembly, the telescoping assembly is fixed on a platform frame, the turnover assembly is installed at the output end of the telescoping assembly, and the telescoping assembly comprises an outer frame, an inner frame, a fixed block, a gear and a rack. The turnover assembly comprises a front sealing plate, an adapting frame, an overturning plate, a first butt joint block, a connecting hook and a second butt joint block. The limiting assembly comprises a first limiting block, a second limiting block and a limiting pin. According to the invention, one translational degree of freedom is added, the fault-tolerant capability of the final assembly platform is improved, the adaptability of the platform in the aspect of size is improved, one set of platform can meet the general assembly and test of two or morespacecrafts, and the general assembly test work can be more effectively carried out on the spacecrafts.

Description

technical field [0001] The invention belongs to the field of spacecraft ground testing and experimentation, and relates to a telescoping mechanism of an assembly platform. Background technique [0002] With the rapid development of my country's aerospace industry, especially the demand for large and medium-sized spacecraft in the final assembly test is getting higher and higher. The final assembly platform is an indispensable ground tooling equipment in the process of manned spacecraft final assembly test. It is used for hoisting and docking of each cabin section of the spacecraft in a vertical state, general assembly, personnel entry and exit of the entire spacecraft in a vertical parking state, and comprehensive electrical performance testing. During the laying and installation of cables, pipelines, and test equipment, it is necessary to meet the general assembly test requirements for hoisting the entire spacecraft in and out of the platform in a vertical state, and pullin...

Problems solved by technology

[0003] With the continuous improvement of spacecraft assembly test requirements, higher requirements are put forward for the supporting equipment during the final assembly test. Although the general assembly platform can meet the normal use of the spacecraft during the spacecraft final assembly test, there are still problems. Now Some general assembly platforms have a simple and intuitive structure. Although they can meet the current spacecraft assembly and testing requirements, they have poor fault tolerance. If a problem occurs in a certain envelope size, it will affect the entire assembly, testing process or production cycle. Moreover, the current general assembly platform Basically, special equipment is used to meet the final assembly and testing of specific spacecraft. The size adaptability and versatility are not good, which not only causes waste of cost and time, but also wastes manpower and material resources. It is not suitable for the current aerospace industry. development needs
