| 为提高圆盘破茬装置设计效率，简化装配操作，分析了参数化设计关键技术，提出了一种基于坐标系约束的自动装配和批量自动装配技术，研究了约束坐标系的建立方法及自动装配实现的步骤；以VC++6.0为编程语言，以Pro/toolkit提供的底层函数为开发工具，对圆盘破茬装置参数化设计及自动装配工作平台进行了二次开发。实例验证结果表明：模型与程序相结合的参数化设计方法编程简单，能够在Pro/E环境下通过界面操作完成零件设计；基于坐标系约束的自动装配技术不需要进行矩阵运算，每个零件针对与其装配的零件只需要建立一个约束坐标系，用户通过选择装配零件和参照零件上相应的坐标系即可完成装配工作；批量自动装配技术适用于装配体约束坐标系位于同一元件或多个相同元件的情况，多个螺栓或螺母的重复装配可一次操作自动完成。本研究提出的参数化设计方法及自动装配技术适用于破茬装置的系列化设计，有利于减少重复性装配工作。 |

| In order to increase design efficiency and reduce assemble work of disc coulter, the key technologies of parametric design were analyzed. The technology of automatic assembling and batch automatic assembling based on constraint coordinate system was presented, and the method of building constraint coordinate system and the steps of realizing automatic assembling were also investigated. The VC ++6.0 software and the underlying functions provided by Pro/toolkit were used to develop the parametric design and automatic assembling platform for disc coulter. The authentication results by real cases showed that the programming was easy by the parametric design method that integrated the model and the program. Parts can be designed by interface operation in the environment of Pro/E. The automatic assembling technology based on constraint coordinate system requires no any matrix operation. Every part only needs to establish a constraint coordinate system for the reference part. User can accomplish assembly by selecting the corresponding coordinate systems for the assemble part and the reference part. The batch automatic assembling technology is applicable to two cases that the assembly constraint coordinate systems are on a part or on many same parts. The assembly of multiple bolts or nuts can be automatically finished by one operation. The parametric design and automatic assembling technology may be applied toward a series of design for disc coulter and are beneficial in decreasing the repetitive assemble work. |
