文档介绍：摘要
五轴联动加工中心有高效率、高精度的特点。若配以五轴联动的高档数控系统,还可以对复杂的空间曲面进行高精度加工,更能够适应像汽车零部件、飞机结构件等现代模具的加工。
本文设计了一台五轴联动机床主轴模型,在XY工作台的基础上叠加两层托板,步进电动机带动轴使其做旋转运动,构成类似陀螺仪的结构。分别实现工作台绕XY轴的转动和移动,再沿Z轴装配一根丝杠完成工作台沿Z轴的上下运动最终实现***向各个面进行加工。
主要完成了:模型整体结构设计,各个轴的结构设计及计算、滚珠丝杠、轴承和直线滚动导轨的选择及其强度分析;步进电机的选择及分析。
关键词五轴联动丝杠传动陀螺仪
Abstract
Five-axis machining center with high efficiency and precision characteristics. If panied by high-C five-axis system, can also carry plex curved surface precision machining, more able to adapt as ponents, aircraft structural parts and other modern mold processing.
This paper designed a five-axis machine tool spindle model, based on the XY table overlay two pallets, stepper motor drive shaft rotation to do so constitutes a similar gyro structure. Were achieved around the XY axis rotating table and move along the Z axis and plete the table assembly of a screw up and down movement along the Z axis to the ultimate realization of the various surface processing tool.
pleted: overall structural design model, each shaft structure design and calculation, ball screws, bearings and linear motion guide the choice and strength analysis; stepper motor selection and analysis.
Keywords five-axis gyro screw drive
