大直径辊筒专用外圆磨床设计

摘要

随着社会和科技的发展，对机械零件的精度和表面质量要求越来越高，各种高硬度材料的应用日益增多，磨床的使用范围日益扩大。，在精密加工当中，有许多零部件是通过精密磨削来达到其要求的，而精密磨削加工会要在相应的精密磨床上进行，因此精磨磨床在精密加工中占有举足轻重的作用。此外，对磨床的环保要求越来越高，绝大部分的机床产品都采用全封闭的罩壳，绝对没有切屑或切削液外溅的现象。本文主要研究的是大直径滚筒外圆专用磨床的导轨设计和磨头设计，导轨和磨头的设计影响磨床的精度，设计时，必须从实际情况出发，有机地结合各种导轨和主轴箱形式，力求设计出结构简单、工作可靠、成本低、调整维修方便的导轨和合理的主轴。

Abstract

Along with the development of the society and science and technology, more and more high request to accuracy and surface quality of machine spare parts, the application of various high degree of hardness material increases day by day and the use of grinding machine scope extends day by day., Process in the precision-machined , there are many zero partses whetting to pare to attain its request through a nicety, but the nicety whet to pare to process would at correspond of precise grinding machine up carry on, so the Jing whet grinding machine to occupy a prominent function in the nicety process.In addition, more and more high to the environmental protection request of grinding machine, the tool machine products of overwhelming majority all adopt the cover hull of whole closingses, absolutely didn't slice scraps or slice to pare the phenomenon that the liquid outside splashes.This text mainly what to study be circle track design and emery wheel mounting of the lead of appropriation grinding machine to account out of the big diameter roller, guide rail and wheelhead design influence the accuracy of the grinding machine, have to from actual the circumstance set out and organically combine various guide rail and principal axis box form, try hard for to design a structure in brief, work credibility, the cost is conveniently low and adjusts to maintain a reasonable principal axis and guide rail .

Keywords:special purpose grinding machine, big diameter roller, guide rail, wheelhead
