電動扳手是指擰緊和旋松螺栓及螺母的電動工具，是一種擰緊螺栓的工具。用于鋼結(jié)構(gòu)橋梁、廠房建筑、化工、發(fā)電設(shè)備安裝大六角頭螺栓施工的初擰、終擰和扭剪型螺栓的初擰，以及對螺栓緊固件的扭矩或軸向力有嚴(yán)格要求的場合。
Electric wrench refers to an electric tool used to tighten and loosen bolts and nuts, and is a tool for tightening bolts. Used for the initial tightening, final tightening, and initial tightening of shear type bolts for the installation of large hexagonal head bolts in steel structure bridges, factory buildings, chemical engineering, and power generation equipment, as well as in situations where there are strict requirements for the torque or axial force of bolt fasteners.
電動扳手的產(chǎn)品名稱型號不同，用途使用范圍也不同。這里介紹定轉(zhuǎn)矩電動扳手，供使用參考。
The product names and models of electric wrenches vary, and their usage ranges also vary. Here is an introduction to fixed torque electric wrenches for reference.
定轉(zhuǎn)矩電動扳手是一種能自動控制轉(zhuǎn)矩的電動扳手。它適用于需要用螺栓連接的橋梁結(jié)構(gòu)、大型鋼塔、轉(zhuǎn)矩穩(wěn)定等優(yōu)點。
Fixed torque electric wrench is a type of electric wrench that can automatically control torque. It is suitable for bridge structures that require bolted connections, large steel towers, torque stability, and other advantages.
我國自行設(shè)計、制造的120kgf·m定轉(zhuǎn)矩電動扳手是一種靜轉(zhuǎn)矩結(jié)構(gòu)的扳手。它可作為螺栓的終擰工具，即把初擰過的螺栓再擰到規(guī)定的
The 120kgf · m fixed torque electric wrench designed and manufactured by China is a type of wrench with a static torque structure. It can be used as a final tightening tool for bolts, that is, to tighten the initially tightened bolts to the specified value
電動扳手是裝卸螺紋聯(lián)接件的手持式電動工具，應(yīng)用于汽車、拖拉機、電機電器、動力機械、閥門、水泵、紡織機械等制造業(yè)的裝配工作中，在化工、水泥預(yù)制件、塑料成型等作業(yè)中則用于生產(chǎn)流程中裝拆真空罐、反應(yīng)釜和水泥模板、帶螺紋塑料件的脫模工作；也可用在鐵道、橋梁、建筑等工程中作水泥軌枕、桁架節(jié)點、角鋼腳手架等結(jié)構(gòu)的安裝、檢修和拆換工作。
Electric wrench is a handheld electric tool used for loading and unloading threaded connectors. It is used in the assembly work of manufacturing industries such as automobiles, tractors, electric motors, power machinery, valves, water pumps, textile machinery, etc. In chemical engineering, cement prefabrication, plastic molding, and other operations, it is used for the assembly and disassembly of vacuum tanks, reaction kettles, cement templates, and demolding of threaded plastic parts in the production process; It can also be used for the installation, maintenance, and replacement of cement sleepers, truss nodes, angle steel scaffolding, and other structures in railway, bridge, construction, and other engineering projects.
