摘要  活塞杆是大量生产设备的主要部件，尤其是减震器上的主要零件，所以活塞杆两端螺纹内部的杂质需要螺纹抛光机快速清除，并且保证工件质量满足工艺要求。此活塞杆的材料为45钢，零件外形尺寸为350～460mm且清洁度要求：螺纹牙形内部不能存在铁屑等杂质D<0.2mm的微小颗粒.
本文是基于此进行设计抛光机。其原理是抛光机利用抛光轮的旋转抛光螺纹，而抛光轮在电机主轴直接带动下，通过由PLC（可编程控制器）控制各气压缸的动作来实现抛光。根据这一原理，对抛光机的结构方案进行设计，选择出合适的部件。此螺纹抛光机最终能通过按开始按钮或停止按钮实现自动进料、自动出料。抛光效率为：3秒／支；结合现场实际条件实现最大程度的自动化；抛光机的低成本，噪声小等特点。

Design of the Thread Polisher
Abstract  Piston rod is the main component of the production equiptment,specially in the shocker absorber, so inclusions of the thread in the both end of piston rod were promptly removed by the thread polisher in order to ensure the parts quality of meeting the process requirement . Material of the piston rod is 45 steel , outside dimensions are 350～460mm and the desired  cleanliness: the diameter of iron chips or other particles in the thread socket are less than 0.2mm
Based on the above conditions, thread polisher was designed. Working principle of this polisher involves polishing the thread by employed the rotation of polishing wheel which directly drives through the shaft of motor under controling the each cylinder by the PLC. According to the principle, structure of the polisher was designed and calculated to select the appropriate components. This thread polisher finally realized to feed and unloading the works automatically which can press the button“start” and “stop”. Polishing efficiency is 3s percent each piece; combining the spot conditions to realize the maximal degree of automation，and it has the merit of the low cost and noise and so on.
