定扭矩电动扭力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。定扭矩电动扭力扳手应用于栓焊结构桥梁的架设,厂房、塔架及化工、冶金、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有严格要求的场合。

Constant torque electric torque wrench is a mechanized construction tool for assembling threaded parts and bolts. It has the function of automatic torque control. The constant torque electric torque wrench is used in the erection of bolted and welded bridges, and the installation of plants, towers, chemical, metallurgical and power generation equipment. Assembly of large machinery, lifting equipment and vehicles, and occasions with strict requirements for torque and axial tension of threaded fasteners.
定扭矩电动扭力扳手特点:
Features of constant torque electric torque wrench:
电动扭力扳手由主机和控制仪两部分组成,主机采用双重,缘单相串激式电动机和减速机构,结构新颖、体积小、重量轻、安全可靠。由于采用静扭结构,运转平稳,无振动、无冲击,噪音小,操作者不受反力矩的影响,因而劳动强度低。额定电压220V50/60Hz精度±5%。
The electric torque wrench is composed of a host and a controller. The host adopts a double edge single-phase series motor and a reduction mechanism, which has the advantages of novel structure, small volume, light weight, safety and reliability. Due to the static torsion structure, the operation is stable, no vibration, no impact, low noise, and the operator is not affected by the counter torque, so the labor intensity is low. Rated voltage 220V50 / 60Hz, accuracy ± 5%.
电动扭力扳手螺栓的拧紧操作
Tightening operation of electric torque wrench bolt
1、装上反支架,并紧固螺钉。开动主机,使方头销孔与反支架孔相对应,然后装入扳手套筒,插上销钉,并用橡胶圈固定。
1. Install the reverse bracket and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reverse support hole, then install the wrench socket, insert the pin and fix it with a rubber ring.
2、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. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switch of the host to the forward position, and put the wrench socket on the hexagon of the threaded connector.
3、按下电源开关,扳手启动。当反支架臂靠牢支架时(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 and the wrench starts. When the reverse support arm is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop, the tightening is completed, loosen the power switch and tighten the next bolt.
4、扳手自动停止后,靠反支架的弹性形变,使支架臂自动脱离支点,取下扳手。如臂不能脱离支点时,可拨动正反开关,点动电源开关扳手即可取下.
4. After the wrench stops automatically, the elastic deformation of the reverse support makes the support arm automatically separate from the fulcrum and remove the wrench. If the arm cannot be separated from the fulcrum, turn the positive and negative switch and click the power switch wrench to remove it
