网架螺栓节点球加工中心的研制

Development of the Machining Center Used for Bolted Node Sphere

针对网架螺栓节点球的加工问题 ,详细阐述了虚拟球心基准加工的思路和数控 2坐标回转分度及夹紧的方法 ,同时介绍了节点球加工中心的总体设计方案、CNC控制系统及工作循环 ,为网架螺栓节点球的加工提供了一种新的工艺方法和高效、高精度的设备。

This article mainly discusses the way to machine the bolted node sphere. It gives the detail about an approach with which a virtual center of sphere can be machining datum, the way of dividing and clamping through two numerical-controlled axes. Meanwhile, the whole design scheme of a machining center for bolted node sphere's manufacturing and its control system as well as working circulation are illustrated. All those provide a new processing technology and a high precision and efficiency equipment for machining of these parts.
