扭矩扳手的使用整個流程很簡單：設(shè)定好一個需要的扭矩值上限當(dāng)施加的扭矩達到設(shè)定值時扳手會發(fā)出“卡塔”聲響這就代表已經(jīng)緊固不要再加力了。
The entire process of using a torque wrench is simple: set a required upper limit for the torque value. When the applied torque reaches the set value, the wrench will make a "click" sound, indicating that it has been tightened and no more force should be applied.
計算需要的扭矩值這里以高強度螺栓為例：
Calculate the required torque value using high-strength bolts as an example:
終擰扭矩值=扭矩系數(shù)*預(yù)拉力值標準值*螺栓公稱直徑
Final tightening torque value=torque coefficient * standard value of pre tension force * nominal diameter of bolt
設(shè)定好一個需要的扭矩值。操作如下：
Set a desired torque value. The operation is as follows:
調(diào)節(jié)完后中間豎桿可塞回。
After adjustment, the middle vertical rod can be inserted back.
設(shè)定扭矩后將套筒插入方形驅(qū)動頭。
Insert the sleeve into the square drive head after setting the torque.
通過調(diào)整卡子的位置來調(diào)節(jié)順/逆時針旋轉(zhuǎn)方向。
Adjust the clockwise/counterclockwise rotation direction by adjusting the position of the clip.
將套筒套在螺栓頭部或螺母上本示例是套在螺帽上。
Place the sleeve on the bolt head or nut. In this example, it is placed on the nut.
在扭緊的有時候螺帽和螺母會同時轉(zhuǎn)動需要用一個扳手卡緊螺母之后順時針轉(zhuǎn)動扭矩扳手再對螺帽進行緊固。
Sometimes when tightening, the nut and nut will rotate simultaneously. It is necessary to use a wrench to tighten the nut and then turn the torque wrench clockwise to tighten the nut.
在施力過程中按照標準儀器操作規(guī)范其垂直度偏差左右不應(yīng)超過10度。其水平方向上下偏差不應(yīng)超過3度操作人員在使用過程中應(yīng)保證其上下左右施力范圍均不超過15度。
During the application of force, the verticality deviation should not exceed 10 degrees according to the national standard instrument operation specifications. The horizontal deviation should not exceed 3 degrees. The operator should ensure that the range of force application from top, bottom, left, and right does not exceed 15 degrees during use.
聽到“咔嗒”聲后緊固結(jié)束然后應(yīng)及時解除作用力。
After hearing the "click" sound, the tightening should be completed and the force should be released in a timely manner.
扳手是測量工具應(yīng)輕拿輕放不能代替榔頭敲打如長期不用調(diào)節(jié)標尺刻線退扭小數(shù)值處有利于保證扭矩的精度。
Wrenches are measuring tools that should be handled with care and should not be used as a substitute for hammers. If not adjusted for a long time, it is beneficial to retract the scale line to the minimum torque value to ensure torque accuracy.
