定扭矩電動(dòng)扭力扳手是裝配螺紋件及螺栓的機(jī)械化施工工具，具有自動(dòng)控制扭矩功能。定扭矩電動(dòng)扭力扳手應(yīng)用于栓焊結(jié)構(gòu)橋梁的架設(shè)，廠房、塔架及化工、冶金、發(fā)電設(shè)備的安裝。大型機(jī)械、起重設(shè)備和車輛裝配作業(yè)，以及對(duì)螺紋緊固件的扭矩及軸向拉有嚴(yán)格要求的場(chǎng)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.
定扭矩電動(dòng)扭力扳手特點(diǎn)：
Features of constant torque electric torque wrench:
電動(dòng)扭力扳手由主機(jī)和控制儀兩部分組成，主機(jī)采用雙重,緣單相串激式電動(dòng)機(jī)和減速機(jī)構(gòu)，結(jié)構(gòu)新穎、體積小、重量輕、可靠。由于采用靜扭結(jié)構(gòu)，運(yùn)轉(zhuǎn)平穩(wěn)，無振動(dòng)、無沖擊，噪音小，操作者不受反力矩的影響，因而勞動(dòng)強(qiáng)度低。額定電壓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%.
電動(dòng)扭力扳手螺栓的擰緊操作
Tightening operation of electric torque wrench bolt
1、裝上反支架，并緊固螺釘。開動(dòng)主機(jī)，使方頭銷孔與反支架孔相對(duì)應(yīng)，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。
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、將控制儀的扭矩旋鈕調(diào)到所需扭矩值，將主機(jī)正反開關(guān)撥到正轉(zhuǎn)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 host to the forward position, and put the wrench socket on the hexagon of the threaded connector.
3、按下電源開關(guān)，扳手啟動(dòng)。當(dāng)反支架臂靠牢支架時(shí)（支點(diǎn)可以是鄰近的一只螺栓或其他可作支點(diǎn)的位置）螺栓開始擰緊。當(dāng)螺栓扭矩達(dá)到預(yù)定扭矩時(shí)，扳手自動(dòng)停止，緊固完成，松開電源開關(guān)，進(jìn)行下一只螺栓的擰緊工作。
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、扳手自動(dòng)停止后，靠反支架的彈性形變，使支架臂自動(dòng)脫離支點(diǎn)，取下扳手。如臂不能脫離支點(diǎn)時(shí)，可撥動(dòng)正反開關(guān)，點(diǎn)動(dòng)電源開關(guān)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
