内蒙古科技大学毕业设计说明书（毕业论文）PAGE PAGE 46内蒙古科技大学本科生毕业设计说明书（毕业论文）题 目：火车轴坯料校直机学生姓名：学 号：专 业：机械设计制造及其自动化班 级：指导教师：尹明 副教授摘 要机械、汽车、电机等行业大量使用轴类、膏零件，这些零件的原材料在粗加工或热处理等过程中不可避免的会出现弯曲变形，如果不进行校直处理会直接影响工件的后序加工和使用，甚至可能出现相当数量的废品。所以为了能获得下道工序所允许的最小切削量或通过精密校直保证工件达到严格的最终设计公差要求，校直机成了工件热处理后不可缺少的关键设备。本人设计的是普通车轴校直机，该校直机通过液压缸提供的压力对火车轴完成校直工作。通过对自动校直机的工作原理、系统组成以及各部分的功能的认识和了解，完成了对火车车轴校直机的设计。关键词：校直机 液压控制 加载油缸ABSTRACTProfession massive use axes class and so on machinery, automobile, electrical machinery, the pole class components, these components raw material in processes and so on rough machining or heat treatment inevitable can appear the bending strain, if does not carry on alignment processing to be able to affect the work piece directly after foreword processing and the use, even possibly appears the considerable amount the waste product. In order to therefore can obtain the smallest cutting quantity which the evil ways working procedure permits or through the precise alignment guarantee work piece achieve the strict finally design common difference request, after alignment machine has become the work piece heat treatment the essential equipment.I designed the ordinary axle straightener.The straightener provided through the hydraulic cylinder pressure on the train-axis alignment to complete the work. Automatic alignment of the working principle, system composition and functions of various parts of the knowledge and understanding to complete the alignment of the axle drive train design.Keywords: Straightener Control of hydraulic pressure Loads the cylinder目录 TOC \o 1-4 \h \z \u HYPERLINK \l _Toc232740926 摘 要 PAGEREF _Toc232740926 \h I HYPERLINK \l _Toc232740927 ABSTRACT PAGEREF _Toc232740927 \h II HYPERLINK \l _Toc232740928 第一章 绪论 PAGEREF _Toc232740928 \h 1 HYPERLINK \l _Toc232740929 引言 PAGEREF _Toc232740929 \h 1 HYPERLINK \l _Toc232740930 1.1 国内外相关领域技术、产业现状 PAGEREF _Toc232740930 \h 1 HYPERLINK \l _Toc232740931 1.2 校直机发展前景 PAGEREF _Toc232740931 \h 3 HYPERLINK \l _Toc232740932
