由科能仪器厂、上海量具刃具厂和瑞士出品的Ⅱ型万能角度尺,其直尺固紧装置如图1所示。直尺固紧主要是靠偏心柱的偏心作用来达到的。检修中,常发现直尺凹槽部分磨损,而直尺凹槽研磨后,其与圆盘之间的距离缩短了,加上偏心柱和固定板的磨损,致使直尺固紧部分不起作用。可见这种结构的修理、调整都不甚方便。前几年,我们在原结构的基础上,进行了
By Keneng Instrument Factory, Shanghai Measuring Tool & Cutting Tool Factory and Switzerland produced Ⅱ universal angle feet, ruler fastening device shown in Figure 1. Ruler tightening is mainly due to the eccentric column eccentric to achieve. Overhaul, often found that the ruler groove part of the wear, and ruler groove grinding, the distance between the disc shortened, coupled with the eccentric column and the fixed plate wear, resulting ruler fastening part does not work . This structure can be seen the repair, adjustment is not very convenient. A few years ago, we conducted on the basis of the original structure
