摘　　要：面向第三代核电主管道,根据其结构特征设计了一种内置导轨主管道内表面加工装置。采用计算机辅助设计和模块化设计的现代设计方法,将铣削头置于弯管内部,依据沿导轨进给铣削加工的思想,划分了可实现该方案的各个功能模块并具体设计,包括传动模块、运动模块、导轨模块、定位模块以及动力模块等。铣削头内置沿导轨铣削加工的设计可以有效地避免核电主管道弯管加工中出现的干涉与切削状态不均匀问题,为大长径比弯管内表面机加工提供一种可行的方案。The third-generation nuclear main pipe is taken as the research prototype. Considering structural characterislics of the pipe, a design for its inner surface milling device with built-in guide is given. With the help of computer aided and modular design methods, based on the idea of placing the milling head in pipe and feed along the guide to carry out the machining process, function modules are divided which can realize the plan. The details of modules are given respectively, including transmission module, motion module, guide module, positioning module and power module. The design results show that, the idea of placing the milling head in pipe and feeding along the guide avoids the interference and uneven cutting state problems effectively.
