攀枝花学院 Pan-zhihua University 本科毕业设计说明书 包装机中特殊螺距的设计及加工 院 （系）： 机电工程学院 专 业： 机械设计制造及其自动化 班 级： 2008级机械电子（1）班 学生姓名： 钟 吉 东 学 号： 200810601195 指导老师： 周 丹 二○一二年 三 月 二十 日 摘 要 在现代包装机械，输送设备螺旋输送机系统，它散装物体或容器，如瓶，罐，盒等或不的，按照，发挥了重要作用。本文研究了，用于供送圆柱形物体的形成过程。其次的数学模型，计算机辅助设计（使用了Pro / ENGINEER5.0软件）创建圆柱形物体螺杆的，并最终建立一个三维参数化实体模型。 关键词：分件供送螺杆；三段组合式；Pro/Engineer；三维参数化实体模型 Abstract Classified feeding screw is a modern packaging machinery in conveying system of a main conveying device, it will show a regular or irregular arrangement of the batches of objects or containers such as bottles, cans, boxes, according to the process requirements, one by one, stably supplied to the packaging station plays a key role in. This paper firstly studies the commonly used three section combined type feeding screw feeding cylindrical object screw spiral groove forming process, and the establishment of form a spiral groove contact line, spiral line intersection and tank bottom spiral line mathematical model. Followed by the use of the contact line, the intersection of line and the bottom of the groove spiral helix mathematical model, studied by means of computer aided design ( using Pro / Engineer software 5 ) establish feeding cylindrical object in the three section combined type feeding screw three-dimensional parametric entity model method, and eventually established the 3D parametric solid model. In order to adapt to the supply container shape diversification, this paper studies the three section combined type feeding screw feeding elliptic cylindrical and rectangular objects, screw spiral groove of the respective forming principle, built form the respective spiral groove of the contact line, spiral line intersection and tank bottom spiral line mathematical model, and construct two a feeding screw in Pro / E three-dimensional parametric model. Application of Pro / Engineer generated by the s
