组合机床多轴箱中齿轮的参数化三维造型

Automatic Parametric Modeling of Gear in Multispindle Box of Transfer and Unit Machine

多轴箱是组合机床上的一个重要组成部件,主要是用来安装主轴、传动轴及齿轮等。其主要按专用要求进行设计,由通用零件组成,根据被加工零件的要求安排主轴的位置,并将动力和运动由电机或动力部件传给各个主轴。而在多轴箱设计中,齿轮设计是核心,由于多轴箱中的齿轮都是标准化,所以传统的齿轮设计过程显得繁琐。通过采用VB+Access对数据库中的数据进行提取和显示,根据显示的齿轮参数数据通过CATIA的二次开发生成齿轮。

Multispindle Box as an important component of Portfolio-Tool,is mainly used to install spindles,transmission shafts,gears and so on,it mainly requests fixed function to carry on a design and constitutes of parts in general use,according to parts being processed to arrange principal axis,and make power and sport being passed to them by electric motor or power parts.And gear designing is core of designing of multispindle box,the gears in multispindle box are all standardize,so process of traditional design seems to be tedious.Use VB ＋ Access to extract and display database,according to gear parameters displayed generate gear thought secondary development of CATIA
