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.

    本发明提供了总装平台伸缩机构,属于航天器地面测试试验领域,包括伸缩组件和翻转组件,所述伸缩组件固定在平台框架上,所述翻转组件安装在伸缩组件的输出端,伸缩组件包括外框、内框、固定块、齿轮和齿条,翻转组件包括前封板、适应框、翻板、第一对接块、连接钩和第二对接块,限位组件包括第一限位块、第二限位块和限位销。本发明增加了一个平动自由度,提高了总装平台的容错能力,增加了平台尺寸方面的适应性,一套平台可以满足两种甚至更多种航天器的总装与测试,可以更有效的对航天器进行总装测试工作。
