我厂生产的激光眼科治疗机中有一个关键零件——激光发生器谐振腔体,如图1所示。由于该零件内孔光洁度要求高,镀银前须达9以上,否则镀银后无法达到要求。我们原先采用将抛光芯棒夹在车床的卡盘上旋转,手握零件抛光,结果至多光洁度达到8,且易出现较大的形状误差,划伤也很严重。为此我们设计了一个简单的抛研专用设备,圆满地解决了问题。该抛研装置如图2所示,是用一台380 W电机驱动,用减速器使得曲柄
I plant a laser eye treatment machine has a key part - the laser resonator cavity, shown in Figure 1. Due to the high requirement of inner hole finish of this part, it is necessary to reach more than 9 before silver plating, otherwise it can not meet the requirements after silver plating. We originally used the polishing mandrel clip on the lathe chuck rotation, hand-polished parts, the results up to finish 8, and prone to greater shape error, scratches are also very serious. For this reason we have designed a simple throwing special equipment, satisfactorily solve the problem. The polishing device shown in Figure 2, is a 380 W motor drive, with a gear so that the crank
