电动扳手是指拧紧和旋松螺栓及螺母的电动工具

电动扳手是指拧紧和旋松螺栓及螺母的电动工具,是一种拧紧高强度螺栓的工具。电动扳手主要应用于钢结构安装行业(其中包括石油化工,船舶制造、修理等行业)。

Electric wrench refers to an electric tool for tightening and loosening bolts and nuts. It is a tool for tightening high-strength bolts. Electric wrenches are mainly used in steel structure installation industry (including petrochemical, shipbuilding, repair and other industries).
电动扳手的原理就是在紧固螺丝螺栓螺母等螺纹紧固件时需要控制施加的力矩大小,以保证螺纹紧固且不至于因力矩过大破坏螺纹,所以用扭矩扳手来操作。电动扭矩扳手也叫扭力扳手或力矩扳手,力矩就是力和距离的乘积。操作时,首先设定好一个需要的扭矩值上限,当施加的扭矩达到设定值时,电动扳手会自动停止。
The principle of electric wrench is to control the applied torque when tightening screw, bolt, nut and other threaded fasteners, so as to ensure that the thread is tightened and will not damage the thread due to excessive torque, so it is operated with torque wrench. Electric torque wrench is also called torque wrench or torque wrench. Torque is the product of force and distance. During operation, first set an upper limit of the required torque value. When the applied torque reaches the set value, the electric wrench will stop automatically.
电动扳手分类
Classification of electric wrenches
电动扳手主要分为冲击式电动扳手,电动扭剪扳手,电动定扭矩扳手,电动转角扳手和电动角向扳手。它们的使用方法也是各不相同,下面就是他们的介绍方法。
Electric wrenches are mainly divided into impact electric wrenches, electric torsion shear wrenches, electric constant torque wrenches, electric angle wrenches and electric angle wrenches. Their use methods are also different. The following is their introduction.
电动扭矩扳手
冲击电动扳手:主要是初紧螺栓的,它的操作简单,就是对准螺栓扳动电源开关就行。
Impact electric wrench: it is mainly used to initially tighten the bolt. Its operation is simple, that is, align the bolt and pull the power switch.
电动扭剪扳手:主要是终紧扭剪型高强螺栓的,它的使用就是对准螺栓扳动电源开关,直到把扭剪型高强螺栓的梅花头打断为止。
Electric torsion shear wrench: it is mainly used to finally tighten the torsion shear high-strength bolt. Its use is to align the bolt and pull the power switch until the plum blossom head of the torsion shear high-strength bolt is broken.
电动定扭矩扳手:既可初紧又可终紧,它的使用是先调节扭矩,再紧固螺栓。
Electric constant torque wrench: it can be tightened initially and finally. Its use is to adjust the torque first and then tighten the bolts.
电动转角扳手:主要也属于定扭矩扳手的一种,它的使用是先调节旋转度数,再紧固螺栓。
Electric angle wrench: it mainly belongs to a kind of constant torque wrench. Its use is to adjust the rotation degree first, and then tighten the bolt.
电动角向扳手:是一种专门紧固钢架夹角部位螺栓的电动扳手,它的使用和电动扭剪扳手原理一样。
Electric angle wrench: it is an electric wrench specially used to fasten the bolts at the included angle of the steel frame. Its use principle is the same as that of the electric torsion shear wrench.
