设计简介
摘 要
近年来，国内对于砂带磨削的研究成果有很大的进展，从低质量产品到半成品以及成品的进口和不断学习，使得砂带磨削在我国有了雨后春笋般的发展。
本文主要设计外圆表面砂带光整加工装置机构，主要包括工件的驱动和夹持装置、砂带磨削装置和回转顶尖固定装置三大部分结构设计。工件驱动装置由交流电动机通过带传动直接对工件进行驱动，由变频器调节速度，满足不同尺寸工件的转速要求；采用三爪卡盘夹持工件，回转顶尖支撑，提高工件的支撑刚度。砂带磨削加工装置主要包括收放带带轮及其电机、接触轮、张紧轮、导向轮等结构；针对砂带磨削装置所占空间过大问题，论文设计了三层空间布局，可对径向和轴向进给分别控制。光整加工装备整体结构中由交流直线往复电机实现轴向进给功能，安装方式为反装，可有效减少磨削装置所占空间。装置总体结构研究得出两种方案进行对比，最终选择经济效益较好的三导柱机构方案。
论文所设计光整加工装备可对直径为60-150mm，最大长度为600mm的外圆表面进行光整加工。

ABSTRACT
In recent years, the domestic research on the grinding of the belt has made great progress, from low-quality products to semi-finished products and finished products imported and continuous learning, making the belt grinding in China has mushroomed development.
In this paper, we mainly design the mechanism of the belt finishing device, and make two kinds of schemes to compare and finally choose the three-pillar mechanism with better economic benefits. Then the design of the spindle form and strength check, the choice of motor and workpiece clamping device, clamping device selection of common three-jaw chuck, rotary top support, improve the support stiffness of the workpiece. Followed by the design of the tailstock tailstock fixed device, and finally the design of belt grinding device. Mainly drive motor, retractable pulley, contact wheel, tension wheel and other structures. In order to save the device space, the paper design on the middle and lower three-dimensional layout, radial and axial feed can be controlled separately.
The finishing equipment can be designed for the finishing of the outer surface of the diameter of 60-150mm and the maximum length of 600mm.
Key Words：Cylindrical grinding device；Finishing；Belt
