大家都用過扭力扳手，使用時它發(fā)出卡塔聲音后是提示已達到你要求的扭矩值了。下面咱們小編講解一下電動扭力扳手的內(nèi)部結構：
Everyone has used a torque wrench. When it is used, it makes a cata sound, which indicates that the torque value you require has been reached. Let's explain the internal structure of the electric torque wrench:
扭矩扳手所發(fā)出的“卡塔”是由本身內(nèi)部的扭矩釋放結構產(chǎn)生的，其結構分為壓力彈簧、扭矩釋放關節(jié)、扭矩頂桿三結構所組成。在扭矩扳手上設定所需扭矩值（由彈簧套在頂桿上向扭矩釋放關節(jié)施壓），鎖定扭矩扳手，開始擰緊螺栓。當螺栓達到扭矩值（當使用扭力大于彈簧的壓力）后，會產(chǎn)生瞬間脫節(jié)的效應。在產(chǎn)生脫節(jié)效應的瞬間發(fā)出關節(jié)敲擊，扳手金屬外殼所發(fā)出的“卡塔”聲。
The "lata" emitted by the torque wrench is generated by its own internal torque release structure, which is divided into three structures: pressure spring, torque release joint and torque ejector rod. First, set the required torque value on the torque wrench (press the torque release joint by the spring sleeve on the ejector rod), lock the torque wrench and start tightening the bolts. When the bolt reaches the torque value (when the torque used is greater than the pressure of the spring), it will produce the effect of instantaneous disconnection. At the moment of disjointed effect, the joint knock and the "Kata" sound emitted by the metal shell of the wrench are sent out.
扭力扳手也叫扭矩扳手，力矩就是力和距離的乘積，在緊固螺絲螺栓螺母等螺紋緊固件時需要控制施加的力矩大小，以保證螺紋緊固且不于因力矩過大破壞螺紋，所以用扭矩扳手來操作。
Torque wrench is also called torque wrench. Torque is the product of force and distance. When tightening threaded fasteners such as screws, bolts and nuts, it is necessary to control the applied torque to ensure that the threads are tightened and will not damage the threads due to excessive torque, so it is operated with torque wrench.
設定好一個需要的扭矩值上限，當施加的扭矩達到設定值時，扳手會發(fā)出“卡塔”聲響或者扳手連接處折彎一點角度，這就代表已經(jīng)緊固不要再加力了。
First, set an upper limit of the required torque value. When the applied torque reaches the set value, the wrench will make a "click" sound or bend a little angle at the wrench connection, which means that it has been tightened and no more force is added.
1、設定扭矩后，將套筒插入方形驅(qū)動頭。
1. After setting the torque, insert the sleeve into the square drive head.
2、將套筒套在螺栓頭部或螺母上。
2. Put the sleeve over the bolt head or nut.
3、將扭力扳手向右轉(zhuǎn)動進行緊固。
3. Tighten the torque wrench by turning it to the right.
4、聽到“咔嗒”聲后，緊固結束。
4. After hearing the "click", the fastening is completed.
扭力板手使用注意事項
Precautions for use of torque wrench
施加扭矩時，手握在扭矩扳手手柄中間刻度線位置。方頭與套筒、螺母穩(wěn)固連接。只能在所知扳手標注的方向上施力，同時施力方向應在正負15度內(nèi)。
When applying torque, hold the middle scale mark of the torque wrench handle. The square head is firmly connected with the sleeve and nut. The force can only be applied in the direction marked by the known wrench, and the force application direction shall be within plus or minus 15 degrees.
