1、XXX学校毕业论文机械制造毕业设计摘要本次螺纹抛光机的设计目的主要是用来抛光活塞杆两端的螺纹.抛光螺纹的目的是为了使螺纹牙形内部没有铁屑杂质,避免活塞杆螺纹与锁紧螺母之间产生虚假扭矩而影响装配精度,导致产品的品质和寿命降低.基本的设计思路是通过电机带动砂轮旋转抛光活塞杆的螺纹端部，砂轮是由大量的细钢丝组成。在整个加工过程中，电机的左右移动，待加工件的送入及送出，工件的夹紧都是由各气压缸联动来实现的。而气压缸的行程和进给速度则是由PLC（可编程控制器）来实现的。在砂轮进行抛光前必须对各气压缸的行程进行调节，特别是上部的压紧气压缸和砂轮下方的顶紧定位气压缸的行程。各气压

2、缸的行程通过电磁阀调节压力来实现。其中送料气压缸和顶紧定位气压缸的时间差(5S)以及抛光时间（3S）由延时继电器控制,其延时的时间是通过实验来总结决定的。操纵系统由开始按钮、停止按钮、循环按钮、急停按钮等组成。本次设计的结构支架是采用焊接式的；电机，气压缸都是通过螺纹连接固定在支座或者是支架上；电机支座连接在支架上的光杠和螺杆装置上，通过螺杆来调节电机的位置。关键词：螺纹抛光气压缸螺纹抛光机XXX学校毕业论文TITLE：AMACHINEDESIGNOFTHETHREADPOLISHAbstracts:Thethreadbuffingmachineisusesfort
