Why does the torque wrench produce chattering? The principle is very simple. Let's explore it together

　　力矩扳手的原理(力矩扳手)產(chǎn)生的聲音是很簡單的cata，可以分為以下幾個步驟來理解:

　　The principle of torque wrench (torque wrench) is to produce a simple cat a, which can be understood in the following steps:

　　1. 轉(zhuǎn)矩扳手表示您需要的轉(zhuǎn)矩值在“cata”聲后到達;

　　1. The torque wrench indicates that the torque value you need reaches after the "cata" sound;

　　2. 扭矩扳手產(chǎn)生的“cata”是由內(nèi)部扭矩釋放機構(gòu)產(chǎn)生的，內(nèi)部扭矩釋放機構(gòu)由壓力彈簧、扭矩釋放接頭和扭矩噴射器三部分組成。

　　2. "Cata" produced by torque wrench is produced by internal torque release mechanism, which consists of pressure spring, torque release joint and torque injector.

　　3.，在扭矩扳手上設(shè)置所需的扭矩值(彈射桿上設(shè)置彈簧，按下扭矩釋放接頭)，鎖緊扭矩扳手，擰緊螺栓。當螺栓達到扭矩值時(當施加的扭矩大于彈簧壓力時)，立即斷開。在脫臼的瞬間，關(guān)節(jié)受到撞擊，扳手的金屬外殼發(fā)出“卡塔”的聲音。這是為了確認力矩值的警示作用(其實就像我們的手臂關(guān)節(jié)在15度彎曲的鐵管中立即伸直就會擊中鋼管的原理)。

　　3. First, set the required torque value on the torque wrench (set the spring on the ejection rod and press the torque release joint), lock the torque wrench and tighten the bolts. When the bolt reaches the torque value (when the applied torque is greater than the spring pressure), disconnect immediately. At the moment of dislocation, the joint is hit, and the metal shell of the wrench makes a "Kata" sound. This is to confirm the warning effect of the torque value (actually, it's just like the principle that our arm joint will hit the steel pipe if it straightens immediately in the 15 degree bending iron pipe).

　　上面說的是更常用的手動扭矩扳手，除了電動扭矩扳手、氣動扭矩扳手等。

　　Above said is the most commonly used manual torque wrench, in addition to electric torque wrench, pneumatic torque wrench, etc.
