岩心钻探所用的机具有些锥形体零件,如钻杆锁接手,取心卡簧、卡簧座,打捞矢锥等,用量大,加工工时多.为了保证加工质量,提高加工效率,在领导支持和老师付们的协助下,我们技革组改装了C620车床,用挂轮法加工锥形体零件,取得了成功.挂轮装置如图所示,将车床拖板箱内Ⅲ轴接长30 Core drilling machine used to have some conical body parts, such as the drill pipe lock hand, take the card spring, spring seat, etc., in large quantities, processing hours and more.In order to ensure processing quality and improve processing efficiency, leadership support and With the assistance of the teacher, we modified the C620 lathe in our technology group and processed the conical body parts with the hanging-wheel method, and achieved success. As shown in the figure, the length of the shaft in the lathe pallet is 30
