我厂在设备维修、备件制造和机床研制过程中,经常迁到偏心轴和偏心套等零件。过去多用四爪卡盘找正偏心或用计算好的垫片垫三爪卡盘车制,在车制中效率低、操作不方便。后来革新一个车偏心卡盘(见图),加工偏心零件操作方便,节省辅助时间,提高了生产效率。这种偏心卡盘又叫双法兰差位卡盘,制造简单,把法兰做成两个,中间一个法兰上下活动带动卡盘,偏心距的大 I plant equipment maintenance, spare parts manufacturing and machine tool development process, often moved to eccentric shaft and eccentric sleeve and other parts. In the past, the use of four-jaw chuck to find the eccentric or with a good pad pad three-jaw chuck car system, the efficiency is low, the operation is not convenient. Later, innovation of a car eccentric chuck (see photo), processing eccentric parts easy to operate, saving auxiliary time, improve production efficiency. This eccentric chuck, also known as double flange differential chuck, the manufacture is simple, the flange made of two, the middle of a flange up and down the activities of the chuck, the eccentricity of the large
