一.扭剪型電動扭矩扳手是一種終緊扭剪型高強度螺栓的工具,一般有電動扭剪扳手和手動扭剪扳手,其中電動扭剪扳手比較常見。
1、 The electric torque wrench of the torsion shear type is a tool for final tightening high-strength bolts of the torsion shear type. There are generally electric and manual torsion shear wrenches, among which electric torsion shear wrenches are more common.
二.扭剪型電動扭矩扳手的應(yīng)用:
2、 Application of torsion shear electric torque wrench:
扭剪型高強螺栓的初緊可使用沖擊電動扳手或定扭矩扳手,而終緊必須使用扭剪扳手,所以扭剪扳手是專門終緊扭剪型高強螺栓的。
The initial tightening of shear type high-strength bolts can be done using an impact electric wrench or a fixed torque wrench, while the final tightening must be done using a shear wrench. Therefore, shear wrenches are specifically designed for final tightening of shear type high-strength bolts.
三.扭剪型電動扭矩扳手的使用:
3、 The use of a torsion shear electric torque wrench:
扭剪扳手主要是終緊扭剪型高強螺栓的,它的目的就是把扭剪型高強螺栓的梅花頭打斷即可。工作時將扳手頭對準(zhǔn)螺栓頭,扣動開關(guān)即可開始工作,幾秒后,螺栓梅花頭將被扭斷,然后抽出扳手扣動扳機將梅花頭彈出,即結(jié)束工作。
The torsion wrench is mainly used for final tightening of torsion shear high-strength bolts, and its purpose is to break the plum blossom head of the torsion shear high-strength bolt. When working, align the wrench head with the bolt head, press the switch to start working. After a few seconds, the bolt ring head will be twisted and broken. Then, pull out the wrench and pull the trigger to eject the ring head, which ends the work.
四.扭剪型電動扭矩扳手的特點:
4、 The characteristics of torsion shear electric torque wrench:
操作方便、省時省力、方便。
Easy to operate, time-saving and labor-saving, safe and convenient.
五.“定扭矩扳手"
V Fixed torque wrench“
定扭矩扳手一般就是可以設(shè)定扭矩值的電動扳手,也叫定扭矩電動扳手。電動扭矩扳手一般用來緊固大六角高強螺栓,使用時,先把扭矩調(diào)到需要規(guī)定的扭矩,然后緊固螺栓。
A fixed torque wrench is generally an electric wrench that can set a torque value, also known as a fixed torque electric wrench. Electric torque wrenches are generally used to tighten large hexagonal high-strength bolts. When using them, first adjust the torque to the required torque, and then tighten the bolts.
電動定扭扳手分為電流式和動態(tài)扭矩傳感器式兩種,由控制器和擰緊軸組成。電流式定扭扳手根據(jù)電機擰緊過程中電流值的變化來判斷扭力值,當(dāng)達(dá)到預(yù)定扭力時,電機停止工作。動態(tài)扭矩傳感器式是在擰緊軸上安裝有傳感器,時刻監(jiān)測扭力值的變化,當(dāng)達(dá)到預(yù)定扭力時,電機停止工作。
Electric torque wrenches are divided into two types: current type and dynamic torque sensor type, consisting of a controller and a tightening shaft. The current type fixed torque wrench determines the torque value based on the change in current value during the tightening process of the motor. When the predetermined torque is reached, the motor stops working. The dynamic torque sensor type is equipped with a sensor on the tightening shaft to constantly monitor the changes in torque value. When the predetermined torque is reached, the motor stops working.
電動扭矩扳手具有精度高(±2%)、故障率低、壽命長、可編程,可對扭力和角度控制、可多種扭力選擇的優(yōu)點。因為擰大扭矩螺栓會有反作用力,所以一般在大扭矩擰緊工件上都會設(shè)計反作用力臂,防 止操作人員出現(xiàn)事故。
Electric torque wrenches have the advantages of high accuracy (± 2%), low failure rate, long service life, programmability, torque and angle control, and multiple torque options. Due to the reaction force generated by tightening high torque bolts, reaction arms are generally designed on high torque tightened workpieces to prevent safety accidents for operators.
