智能电动扭矩扳手是装配螺纹件及螺栓的机械化施工工具，具有自动控制扭矩功能。应用于栓焊结构桥梁的架设，厂房、塔架及化工、冶、发电设备的安装。大型机械、起重设备和车辆装配作业，以及对螺纹紧固件的扭矩及轴向拉力有严格要求的场合。
Intelligent electric torque wrench is a mechanized construction tool for assembling threaded parts and bolts, with automatic torque control function. It is applied to the erection of bridges with bolted and welded structures, and the installation of plants, towers and chemical, metallurgical and power generation equipment. Large machinery, lifting equipment and vehicle assembly operations, as well as occasions with strict requirements for torque and axial tension of threaded fasteners.
智能电动扭矩扳手螺栓的拧紧操作
Tightening operation of intelligent electric torque wrench bolts
1、装上反力支架，并紧固螺钉。开动智能电动扭矩扳手主机，使方头销孔与反力支架孔相对应，然后装入扳手套筒，插上销钉，并用橡胶圈固定。
1. Install the reaction support and tighten the screws. Start the main engine of the intelligent electric torque wrench, make the square pin hole correspond to the reaction support hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.
2、智能电动扭矩扳手将控制仪的扭矩旋钮调到所需扭矩值，将主机正反开关拨到正转位置，把扳手套筒套在螺纹连接件的六方上。
2. The intelligent electric torque wrench will adjust the torque knob of the controller to the required torque value, turn the forward and reverse switches of the host machine to the forward rotation position, and put the wrench socket on the hexagon of the threaded connection.
3、按下智能电动扭矩扳手电源开关，扳手启动。当反力支架力臂靠牢支架时（支点可以是邻近的一只螺栓或其他可作支点的位置）螺栓开始拧紧。当螺栓扭矩达到预定扭矩时，扳手自动停止，紧固完成，松开电源开关，进行下一只螺栓的拧紧工作。
3. Press the power switch of the intelligent electric torque wrench to start the wrench. When the force arm of the reaction support is close to the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt starts to be tightened. When the bolt torque reaches the predetermined torque, the wrench will stop automatically, and the tightening is completed. Loosen the power switch to tighten the next bolt.
4、智能电动扭矩扳手自动停止后，靠反力支架的弹性形变力，使支架力臂自动脱离支点，取下扳手。如力臂不能脱离支点时，可拨动正反开关，点动电源开关扳手即可取下。
4. After the intelligent electric torque wrench automatically stops, the elastic deformation force of the counter force bracket will make the bracket force arm automatically disengage from the fulcrum and remove the wrench. If the lever arm cannot be separated from the fulcrum, you can toggle the forward and reverse switches, and then jog the power switch wrench to remove it.
