扭力扳手又稱扭力計(jì)、扭力螺釘旋具。它是依據(jù)梁的彎曲原理、扭桿的彎曲原理和螺旋彈簧的壓縮原理而設(shè)計(jì)的，能測(cè)量出作用在螺母上的力矩大小。
Torque wrench is also called torque meter and torque screw driver. It is designed according to the bending principle of the beam, the bending principle of the torsion bar and the compression principle of the coil spring, and can measure the torque acting on the nut.
扭力扳手有一根長(zhǎng)的彈性桿，其一端裝著手柄，另一端裝有方頭或六角頭，在方頭或六角頭上套裝一個(gè)可換的套筒，用鋼珠卡住。在頂端上還裝有一個(gè)長(zhǎng)指針。刻度板固定在柄座上，每格刻度值為1N（或kg/m）。 使用前，先將安裝在扳手上的指示器調(diào)整到所需的力矩，然后扳動(dòng)扳手，當(dāng)達(dá)到該預(yù)定力矩時(shí)，指示器上的指針就會(huì)向銷軸一方轉(zhuǎn)動(dòng)，后指針與銷軸碰撞，通過(guò)音箱信號(hào)或傳感信號(hào)告知操作者。
The torque wrench has a long elastic rod, one end of which is equipped with a handle, and the other end is equipped with a square head or a hexagon head. A replaceable sleeve is set on the square head or the hexagon head, and is clamped with steel balls. There is also a long pointer on the top. The scale plate is fixed on the handle base, and the scale value of each grid is 1n (or kg / M). Before use, first adjust the indicator installed on the wrench to the required torque, and then pull the wrench. When the predetermined torque is reached, the pointer on the indicator will rotate toward the pin shaft, and then the pointer will collide with the pin shaft, and the operator will be informed by the speaker signal or sensing signal.
扭矩扳手（扭力扳手）發(fā)出卡塔聲音的原理很簡(jiǎn)單，可以分為以下幾個(gè)步驟去理解：
The principle that the torque wrench (torque wrench) emits the sound of jamming is very simple and can be understood in the following steps:
1、扭矩扳手在發(fā)出“卡塔”聲后是提示已達(dá)到你要求的扭矩值了；
1. When the torque wrench makes a "click" sound, it indicates that the torque value you require has been reached;
2、扭矩扳手所發(fā)出的“卡塔”是由本身內(nèi)部的扭矩釋放結(jié)構(gòu)產(chǎn)生的，其結(jié)構(gòu)分為壓力彈簧、扭矩釋放關(guān)節(jié)、扭矩頂桿三結(jié)構(gòu)所組成.
2. The "Kata" generated by the torque wrench is generated by the internal torque release structure, which is composed of pressure spring, torque release joint and torque ejector rod
3、在扭矩扳手上設(shè)定所需扭矩值（由彈簧套在頂桿上向扭矩釋放關(guān)節(jié)施壓），鎖定扭矩扳手，開(kāi)始擰緊螺栓。當(dāng)螺栓達(dá)到扭矩值（當(dāng)使用扭力大于彈簧的壓力）后，會(huì)產(chǎn)生瞬間脫節(jié)的效應(yīng)。在產(chǎn)生脫節(jié)效應(yīng)的瞬間發(fā)出關(guān)節(jié)敲擊，扳手金屬外殼所發(fā)出的“卡塔”聲。由此來(lái)確認(rèn)達(dá)到扭矩值的提醒作用(其實(shí)就象我們手臂關(guān)節(jié)成15度彎曲放在鐵管里瞬間申直后會(huì)碰到鋼管的原理一樣）。
3. 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 bolt. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), the effect of instantaneous disconnection will occur. At the moment when the disconnection effect is generated, the joint knock and the "cata" sound from the metal shell of the wrench are emitted. So as to confirm the reminding effect of reaching the torque value (in fact, it is the same as the principle that our arm joint is bent at 15 degrees and placed in the iron pipe for instant straightening, and then it will touch the steel pipe).
