高转速扭剪型电动扳手的拧紧操作
Tightening operation of high speed torsional shear type electric wrench
1、装上反力支架，并紧固螺钉。开动主机，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 host machine to make the square head pin hole correspond to the counter force 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 positive and negative switches of the host to the forward rotation 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 and the wrench starts. When the reaction support arm is firmly against the support (the fulcrum can be an adjacent bolt or other positions that can be used as fulcrums), the bolt starts to tighten. When the bolt torque reaches the predetermined torque, the wrench will stop automatically. After tightening, loosen the power switch and tighten the next bolt.
4、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 wrench stops automatically, the support arm will automatically disengage from the fulcrum by the elastic deformation force of the reaction support, and the wrench will be removed. If the lever arm cannot be separated from the fulcrum, the positive and negative switches can be toggled, and the power switch wrench can be inched to remove it.
高转速扭剪型电动扳手使用方法
Usage of High Speed Torsion Shear Type Electric Wrench
力矩扳手既可初紧又可终紧，它的使用是先调节扭矩，再紧固螺栓。
The torque wrench can be used for initial tightening and final tightening. It is used to adjust the torque before tightening the bolts.
为了不使测量结果因水平和垂直方向上的偏差而产生影响,在测量时,应在加力把持端上施加一个垂直向下的稳定力值， 然后再手动加点力，这样使用值更准确。
In order not to affect the measurement results due to the deviation in the horizontal and vertical directions, a vertical downward stable force value shall be applied on the force application holding end during measurement, and then the point force shall be applied manually, so that the value can be used more accurately.
