The invention provides an on-orbit construction system for a large paraboloid truss structure, and belongs to the field of aerospace. The problems that when a foldable large space structure is launched, the space utilization rate is not high, the size of the folded space structure is limited by the size of a carrier rocket instrument bin, the rigidity and precision requirements of a truss cannot be ensured, and a complex truss structure cannot be formed are solved. The system comprises an assembly space station, a construction unit, a mechanical arm, a precision detection unit and a truss structure, the construction unit is arranged on the assembly space station, the mechanical arm is arranged at the front end of the assembly space station, the precision detection unit is arranged on the end face of the assembly space station, and the construction unit comprises an additive construction module, a preprocessing module and a material library. The mechanical arm is connected with the end effector, the precision detection unit comprises a second holding claw and a laser tracker, and the laser tracker performs area sweeping on a second micro-motion node in the truss structure. The system is mainly used for on-orbit construction of a large paraboloid truss structure.

    本发明提出了一种大型抛物面桁架结构在轨建造系统,属于航空航天领域。解决了可折展型的大型空间结构发射时空间利用率不高,折叠后的尺寸受运载火箭仪器仓的尺寸限制,无法确保桁架的刚度和精度要求、且不能形成结构复杂桁架结构的问题。它包括装配空间站、建造单元、机械臂、精度检测单元和桁架结构,建造单元设置在装配空间站上,机械臂设置在装配空间站的前端,精度检测单元设置在装配空间站的端面上,建造单元包括增材建造模块、预处理模块和素材库,机械臂与末端执行器相连,精度检测单元包括第二抱抓和激光跟踪仪,激光跟踪仪对桁架结构内的第二微动节点进行区域扫掠。它主要用于大型抛物面桁架结构的在轨建造。
