Research on parametric modeling of structures of scraper conveyor

针对刮板输送机结构设计重复率高、效率低的问题,基于Pro/E 5.0三维建模软件实现了刮板输送机关键部件及复杂装配体的参数化建模。刮板输送机关键部件的参数化建模主要包括三维模型创建、设计参数确定、关系设定等3个步骤,以驱动链轮参数化建模为例介绍了关键部件参数化建模过程。刮板输送机复杂装配体的参数化建模基于Pro/Toolkit二次开发技术和Visual Studio 2008实现,以刮板输送机中部槽参数化建模为例,介绍了复杂装配体的参数化建模及虚拟装配过程。通过修改重要的几何参数实现对刮板输送机关键部件及装配体的快速建立、修改和精确造型,为刮板输送机结构优化提供了基础。

In view of problems of high repetition rate and low efficiency of structure design of scraper conveyor,parametric modeling of key components and complex assemblies of scraper conveyor were realized based on Pro/E 5.0 three-dimensional modeling software.Parametric modeling of key components of scraper conveyor mainly includes three steps：3 D model creation,design parameter determination and relationship setting.The parametric modeling process of key components was introduced by taking parametric modeling of drive sprocket as an example.Parametric modeling of complex assemblies of scraper conveyor was implemented based on Pro/Toolkit secondary development technology and Visual Studio 2008.Parametric modeling and virtual assembly process of complex assembly was introduced by taking parametric modeling of middle slot of scraper conveyor as an example.Rapid establishment,modification and precise sculpting of the key components and assemblies of scraper conveyor were achieved by modifying important geometric parameters,which provides basis for structural optimization of scraper conveyor.
