同步上料旋转升降系统设计
摘要

同步上料旋转升降系统是用于真空熔炼设备中进行金属重熔精炼的一个重要部件，在金属重熔精炼中起着重要作用。它具有快速上升和慢速下降的功能，在升降的同时具备了旋转功能。快速上升，能有效提高其工作效率；慢速下降及旋转，对净化金属、搞高金属纯度、改善晶体结构起着重要的作用。本文设计选用双滚珠丝杠副作为升降系统，传动方式为丝杠回转运动——螺母移动；通过螺母移动带动中间轴升降的同时，用交流伺服电机驱动中间轴旋转。本文对该机构的主要组成部件：滚珠丝杠副、减速器、齿轮传动、交流伺服电机等进行了设计计算或选型。此外,本文还对各个零部件进行了设计及其说明，并绘制了零件图以及该机构的装配图。整个机构设计合理，结构紧凑，运动平稳，定位精度和传动效率高，能有效实现其同步旋转升降的功能。

Abstract
Rotating synchronous lifting system of feeding is an important componentwhich is used invacuum equipment for metal remelting and refining. It plays an important role in metal remelting and refining. It has rapidly increased and slow decline simultaneously revolved in function. When it rises fast, it can effectively improve thework efficiency. When it is slow down and rotate, it plays an important role in making high purity of metal, improving crystal structure and purification of metal. Therefore it is meaningful to design of this mechanism. The article selected as a double Ball guide screwvice lifting system. The type of drive is that ball screw is rotation movement and the nuts move; the nuts drive the intermediate shaft to rise and fall, and at the same time, the intermediate shaft driven by AC servo motor rotating. In this paper, the main components of the mechanical components: Ball guide screwvice, speed reducer, gear drives, AC servo motor etc. has been designed, such as computing or selection. In addition, the article has also carried out invarious parts of the design and description, and has drawn up the detail drawing aswell as this organization assembly drawing. The design is reasonable. The entire machine structure is compact and smooth movement. The positioning accuracy and the transmission efficiency are so high. It can also effectively achieve the function of synchronous rotation movements.
