Abstract

The tightening method using impact wrenches is used rather frequently to clamp bolted joints requiring high workability. The tightening torque is applied in the form of impact forces generated by a rotating hammer, which is powered by compressed air, hydraulic force or electric power. The primary advantage of impact wrenches is that the tightening operation can be completed in a short time. However, the accuracy of the generated bolt force is not so high, because of the complicated mechanical behavior caused by the action of impact forces. In this paper, the tightening process of bolted joints by use of impact wrenches is studied from the mechanical point of view, and the relationship between the nut rotation angle and the repeat count of impact forces is formulated. Based on the foregoing results, a practical tightening guideline is proposed by considering the effects of joint stiffness and impact friction coefficient that vary in the progress of the tightening operation.

使用冲击扳手拧紧螺栓的力学特性

使用冲击扳手的紧固方法经常被用于对可加工性要求高的螺栓连接进行夹紧。拧紧扭矩以旋转锤产生的冲击力的形式施加，该锤由压缩空气、液压力或电力驱动。冲击扳手的主要优点是可以在短时间内完成拧紧操作。然而，由于冲击力的作用所引起的力学行为复杂，所产生的螺栓力的精度不是很高。本文从力学角度研究了冲击扳手紧固螺栓接头的过程，给出了螺母旋转角度与冲击力重复次数的关系式。在此基础上，考虑关节刚度和冲击摩擦系数在拧紧过程中变化的影响，提出了一种实用的拧紧准则。
