電動(dòng)扭剪扳手具有自動(dòng)控制扭矩的功能，是裝配螺紋零件和螺栓的機(jī)械化施工工具，我廠電動(dòng)扭剪扳手主機(jī)采用雙絕緣單相串激電機(jī)和減速機(jī)構(gòu)，結(jié)構(gòu)新穎，體積小，重量輕，可靠，由于電動(dòng)定扭矩扳手采用靜扭矩結(jié)構(gòu)，運(yùn)行平穩(wěn)，無(wú)振動(dòng)、無(wú)沖擊、無(wú)噪音，操作者不受反扭矩影響，勞動(dòng)強(qiáng)度低，這種電動(dòng)扭剪扳手廣泛應(yīng)用于大型機(jī)械、起重設(shè)備和車(chē)輛裝配作業(yè)，以及對(duì)螺紋緊固件的扭矩和軸向拉力有嚴(yán)格要求的場(chǎng)合，那么如何擰緊電動(dòng)扭剪扳手的螺栓要如何操作：
The electric torque wrench has the function of automatically controlling torque and is a mechanized construction tool for assembling threaded parts and bolts. Our factory's electric torque wrench host uses a double insulated single-phase series excitation motor and a reduction mechanism, with a novel structure, small size, light weight, and safety and reliability. Due to the static torque structure of the electric fixed torque wrench, it runs smoothly, without vibration, impact, or noise, and the operator is not affected by reverse torque, resulting in low labor intensity, This electric torque wrench is widely used in large-scale machinery, lifting equipment, and vehicle assembly operations, as well as in situations where there are strict requirements for the torque and axial tension of threaded fasteners. Therefore, how to tighten the bolts of the electric torque wrench and how to operate it:
1.安裝反作用力支架并擰緊螺釘，啟動(dòng)主機(jī)，使方形銷(xiāo)孔與反作用支架孔相對(duì)應(yīng)，然后安裝扳手套筒，插入銷(xiāo)，用橡膠圈固定。
1. Install the reaction support bracket and tighten the screws, start the main engine so that the square pin hole corresponds to the reaction support bracket hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.
2.將控制器的扭矩旋鈕調(diào)節(jié)到所需的扭矩值，將主機(jī)的正反轉(zhuǎn)開(kāi)關(guān)設(shè)置到前進(jìn)位置，將扳手套筒套在螺紋接頭的六個(gè)面上。
2. Adjust the torque knob of the controller to the desired torque value, set the forward and reverse switches of the host to the forward position, and place the wrench socket on the six faces of the threaded joint.
3.按下電源開(kāi)關(guān)啟動(dòng)扳手，當(dāng)反力支架的力臂緊靠在支架上時(shí)(支點(diǎn)可以是相鄰的螺栓或其他可以作為支點(diǎn)的位置)，螺栓開(kāi)始擰緊，當(dāng)螺栓的扭矩達(dá)到預(yù)定扭矩時(shí)，扳手會(huì)自動(dòng)停止，完成緊固，松開(kāi)電源開(kāi)關(guān)，擰緊下一個(gè)螺栓。
3. Press the power switch to start the wrench. When the force arm of the reaction bracket is tightly against the bracket (the fulcrum can be an adjacent bolt or other position that can serve as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop and complete the tightening. Release the power switch and tighten the next bolt.
4.扳手自動(dòng)停止后，通過(guò)反力支架的彈性變形力，支架的力臂自動(dòng)脫離支點(diǎn)，扳手被取下，如果力臂脫離不了支點(diǎn)，可以撥動(dòng)正反開(kāi)關(guān)，然后點(diǎn)動(dòng)電源開(kāi)關(guān)扳手就可以拆下來(lái)。
4. After the wrench automatically stops, the force arm of the bracket automatically disengages from the fulcrum through the elastic deformation force of the counter force bracket, and the wrench is removed. If the force arm cannot detach from the fulcrum, the forward and backward switches can be toggled, and then the power switch wrench can be removed by clicking.
