测力扳手是飞机装配过程中常用的专用工具之一。结构一般分为弯曲变形测力和扭转变形测力两种,其中又以扭转变形测力结构紧凑、测量力矩大而应用较多。但扭转变形测力扳手结构比较复杂,一般工厂制造困难。我们根据其原理,用普通百分表代替较为复杂的传动读数机构,同样满足了使用要求,简化了制造过程,故称为简 Force wrench is one of the commonly used special tools in the assembly process of aircraft. The structure is generally divided into two kinds of force measurement of bending deformation and force measurement of torsional deformation, of which, torsional deformation force measurement structure is compact, measurement torque is large and more applications. But the torsional deformation wrench structure is more complex, the general factory manufacturing difficulties. According to its principle, we use ordinary dial indicator to replace the more complex transmission reading agencies, also meet the requirements of use, simplifying the manufacturing process, it is called Jane
