電動扭剪扳手具有自動控制扭矩的功能，是裝配螺紋零件和螺栓的機械化施工工具，我廠電動扭剪扳手主機采用雙絕緣單相串激電機和減速機構(gòu)，結(jié)構(gòu)新穎，體積小，重量輕，可靠，由于電動定扭矩扳手采用靜扭矩結(jié)構(gòu)，運行平穩(wěn)，無振動、無沖擊、無噪音，操作者不受反扭矩影響，勞動強度低，這種電動扭剪扳手廣泛應(yīng)用于大型機械、起重設(shè)備和車輛裝配作業(yè)，以及對螺紋緊固件的扭矩和軸向拉力有嚴格要求的場合，那么如何擰緊電動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，啟動主機，使方形銷孔與反作用支架孔相對應(yīng)，然后安裝扳手套筒，插入銷，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，將主機的正反轉(zhuǎn)開關(guān)設(shè)置到前進位置，將扳手套筒套在螺紋接頭的六個面上。
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.按下電源開關(guān)啟動扳手，當反力支架的力臂緊靠在支架上時(支點可以是相鄰的螺栓或其他可以作為支點的位置)，螺栓開始擰緊，當螺栓的扭矩達到預(yù)定扭矩時，扳手會自動停止，完成緊固，松開電源開關(guān)，擰緊下一個螺栓。
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.扳手自動停止后，通過反力支架的彈性變形力，支架的力臂自動脫離支點，扳手被取下，如果力臂脫離不了支點，可以撥動正反開關(guān)，然后點動電源開關(guān)扳手就可以拆下來。
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.
