【摘要】：为了对激光腔体圆弧面进行自动抛光,达到镀银时表面粗糙度Ra0.08的要求,需设计一种具有圆弧轨迹往复运动的装置。根据零件特点,采用无急回特性曲柄摇杆机构产生的运动轨迹完成抛光加工。先确定摇杆摆动角度和长度,运用机械原理的知识,计算出各杆长的长度,再运用Creo2.0软件进行运动学仿真,并通过实物对零件进行抛光试验。结果表明,无急回特性曲柄摇杆自动抛光装置设计方案可行,表面粗糙度检测结果为Ra0.05,能够满足加工要求,可实现一次装夹加工4个工件。
[Abstract]:In order to automatically polishing the arc surface of a laser cavity to meet the requirements of surface roughness Ra0.08 for silver plating, a reciprocating device with circular arc trajectory is designed. According to the characteristics of the parts, the track of the crank rocker mechanism without quick return characteristics is used to finish polishing. Firstly, the swing angle and length of rocker rod are determined, the length of each rod length is calculated by using the knowledge of mechanical principle, and then the kinematics simulation is carried out by using Creo2.0 software, and the polishing test of the parts is carried out through the material object. The results show that the design scheme of automatic polishing device for crank and rocker without quick return characteristic is feasible, and the result of surface roughness measurement is that Ra0.05, can meet the requirements of machining and can be clamped to process 4 workpieces at one time.
