Constant torque electric wrench has the function of automatic torque control. It is a mechanical construction tool for assembling threaded parts and bolts.

定扭矩電動扳手應用

Application of constant torque electric wrench

定扭矩電動扳手廣泛應用于栓焊結構橋梁的架設，廠房、塔架及化工、冶金、發(fā)電設備的安裝。大型機械、起重設備和車輛裝配作業(yè)以及對螺紋緊固件的扭矩及軸向拉力有嚴格要求的場合。

Constant torque electric wrench is widely used in the erection of bolted and welded bridges, the installation of plants, towers and chemical, metallurgical, power generation equipment. Large machinery, lifting equipment and vehicle assembly operations, as well as occasions with strict requirements on torque and axial tension of threaded fasteners.

定扭矩電動扳手螺栓的擰緊操作

Tightening operation of fixed torque electric wrench bolt

1、裝上反力支架，并緊固螺釘。開動主機，使方頭銷孔與反力支架孔相對應，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。

1. Install the reaction support and tighten the screws. Start the main engine to make the square pin hole correspond to the counterforce bracket hole, then install the wrench socket, insert the pin and fix it with rubber ring.

2、將控制儀的扭矩旋鈕調到所需扭矩值，將主機正反開關撥到正轉位置，把扳手套筒套在螺紋連接件的六方上。

2. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switch of the main engine to the forward position, and put the wrench socket on the hexagon of the threaded connector.

3、按下電源開關，扳手啟動。當反力支架力臂靠牢支架時（支點可以是鄰近的一只螺栓或其他可作支點的位置）螺栓開始擰緊。當螺栓扭矩達到預定扭矩時，扳手自動停止，緊固完成，松開電源開關，進行下一只螺栓的擰緊工作。

3. Press the power switch and the wrench starts. When the arm of the reaction support 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 stop automatically, the tightening is completed, the power switch will be loosened, and the next bolt will be tightened.

4、扳手自動停止后，靠反力支架的彈性形變力，使支架力臂自動脫離支點，取下扳手。如力臂不能脫離支點時，可撥動正反開關，點動電源開關扳手即可取下。

4. After the spanner stops automatically, the force arm of the support is automatically separated from the fulcrum by the elastic deformation force of the reaction support, and the spanner is removed. If the force arm can not be separated from the fulcrum, the positive and negative switches can be turned, and the power switch wrench can be turned to remove.
