摘要：

针对传统马架扩孔装置需依靠人工操作芯轴及环件转动的问题，提出了马架扩孔自动进给装置，并进行结构设计，以提高装置的自动化程度。该装置仅适用于小型环件，为了更大程度地满足需求，开发了一套系列化参数化设计系统，通过该系统可快速设计出一套新的扩孔装置，显著提高设计效率。首先，基于Deform在不同压下量和转动角度下进行数值模拟，确定最佳工艺方案，得出各系列环件的参数；然后，通过对构型进行分析，找出装置设计的内在驱动链，推导出各基本参数的计算公式、校核分析等内容，并基于计算机技术为之提供软件支撑，实现装置的系列化设计；最后，利用现有装置基于CATIA软件建立原型模板，通过参数化建模和CATIA二次开发相互结合，开发出高效实用的计算机辅助设计系统，通过输入不同的参数值即可驱动模型的变更，获得满足设计要求的新模型，实现参数化设计。

For the problem that the traditional horse frame reaming device relied on the rotation of mandrel and ring by manual operation, an automatic feeding device of horse frame reaming was proposed and designed to improve the automation degree of device. However, the automatic device was only suitable for small serial of rings. In order to meet the requirements to a greater extent, the serial parametric design system was developed. Through the system, the new reaming device was designed quickly to significantly improve the design efficiency. Firstly, based on Deform, the numerical simulation was carried out under different reductions and rotating angles, the optimal process scheme was determined, and the parameters of each series for rings were obtained. Then, through the analysis of configuration, the internal drive chain of device design was found, and the calculation formula of each basic parameter and check analysis were derived. Furthermore, based on computer technology to provide software support, the serial design of device was realized. Finally, based on CATIA software, the prototype template was established, and through the combination of parametric modeling and secondary development of CATIA, an efficient and practical computer-aided design system was developed. By inputting different parameter values, the model was driven to change, and a new model meeting the design requirements was obtained to realize the parametric design.
