電動扳手主要應用于鋼結構安裝行業(yè)，專門安裝鋼結構高強螺栓，高強度螺栓是用來連接鋼結構接點的，通常是用螺栓群的方式出現(xiàn)。高強螺栓可分為扭剪型和大六角型兩種，國標扭剪型高強螺栓為M16、M20、M22、M24四種，非國標的M27、M30兩種；國標大六角高強螺栓為M16、M20、M22、M24、M27、M30等幾種。一般的對于高強螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴格的扭矩要求。大六角高強螺栓的初緊和終緊都需要使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
Electric wrenches are mainly used in the steel structure installation industry. They are specially used to install high-strength bolts of steel structure. High-strength bolts are used to connect steel structure joints, usually in the form of bolt groups. High strength bolts can be divided into torsion shear type and large hexagon type. There are four kinds of national standard torsion shear high strength bolts: M16, M20, M22 and M24, and two kinds of non-national standard M27 and M30; The national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be first tightened and then finally tightened, and strict torque requirements are required in each step. Constant torque wrench is required for initial and final tightening of large hexagon high strength bolts Therefore, all kinds of electric wrenches are for various fastening needs.
沖擊電動扳手主要是初緊螺栓的，它的使用很簡單，就是對準螺栓扳動電源開關就行。電動扭剪扳手主要是終緊扭剪型高強螺栓的，它的使用就是對準螺栓扳動電源開關，直到把扭剪型高強螺栓的梅花頭打斷為止。電動定扭矩扳手既可初緊又可終緊，它的使用是先調節(jié)扭矩，再緊固螺栓。電動轉角扳手主要也屬于定扭矩扳手的一種，它的使用是先調節(jié)旋轉度數(shù)，再緊固螺栓。電動角向扳手是一種專門緊固鋼架夾角部位螺栓的電動扳手，它的使用和電動扭剪扳手原理一樣。
The impact electric wrench is mainly used to initially tighten the bolt. Its use is very simple. Just aim at the bolt and pull the power switch. The electric torsion shear wrench 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. The electric constant torque wrench can be tightened initially and finally. Its use is to adjust the torque first and then tighten the bolts. Electric angle wrench mainly belongs to a kind of constant torque wrench. Its use is to adjust the rotation degree first, and then tighten the bolt. The electric angle wrench 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.
電動扳手操作規(guī)程
Operating procedures for electric wrench
檢驗試驗及保養(yǎng)
Inspection, test and maintenance
1、電動扳手的金屬外殼應可靠接地，其外殼應有定期檢驗試驗合格證，并在期限內。
1. The metal shell of the electric wrench shall be reliably grounded, and its shell shall be provided with regular inspection and test certificate within the time limit.
2、檢查電動扳手機身安裝螺釘緊固情況，若發(fā)現(xiàn)螺釘松了，應立即重新扭緊，否則會導致電動扳手故障。
2. Check the fastening of the mounting screws on the body of the electric wrench. If the screws are found to be loose, tighten them again immediately, otherwise the electric wrench will fail.
3、檢查手持電動扳手兩側手柄完好，不開裂可破損，安裝牢固。
3. Check that the handles on both sides of the hand-held electric wrench are intact, not cracked or damaged, and installed firmly.
