傳統(tǒng)的扭力扳手演變?yōu)樵O定式棘輪扭力扳手，數(shù)顯式的扭力扳手，預置式扭力扳手等等，雖然類別會有所不同，但是他們的原理大致相同，下面分三個步驟去說明：在扭力扳手上設定所需扭距值(由彈簧套在頂桿上向扭距釋放關節(jié)施壓),鎖定扭距扳手開始擰緊螺栓,當螺栓達到扭距值后(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.由此來確認達到扭距值的提醒作用.(其實就象我們手臂關節(jié)成15度彎曲放在鐵管里瞬間申直后會碰到鋼管的原理一樣)。
The traditional torque wrench has evolved into a set type ratchet torque wrench, a digital display torque wrench, a preset torque wrench, and so on. Although the categories may vary, their principles are roughly the same. The following three steps will explain: first, set the required torque value on the torque wrench (pressure is applied to the torque release joint by the spring on the top 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), there will be an instant detachment effect. At the moment of the detachment effect, there will be a "click" sound from the joint hitting the metal shell of the wrench. This confirms the reminder effect of reaching the torque value (Actually, it's just like the principle that when our arm joints are bent at a 15 degree angle and placed in an iron pipe, they will instantly straighten and touch the steel pipe.).
其次扭力扳手所發(fā)出的"卡塔"是由本身內(nèi)部的扭距釋放結(jié)構(gòu)產(chǎn)生的,其結(jié)構(gòu)分為壓力彈簧,扭距釋放關節(jié),扭距頂桿三結(jié)構(gòu)所組成。后扭力扳手在發(fā)出"卡塔"聲后是提示以達到你要求的扭距值了。扭力扳手使用方法：扭力扳手使用時，當聽到“啪”的一聲時，此時是合適的；在扭力扳手的使用中,要根據(jù)測量部品的要求選取適中量程,所測扭力值不可小於扭力器在使用中量程的百分之二十,太大的量程不宜用於小扭力部品的加固,小量程的扭力器更不可以超量程使用；在使用扭力扳手時,先將受力棘爪連接好輔助配件(如套筒,各類批嘴),確保連接已經(jīng)沒問題.
Secondly, the "jam" emitted by the torque wrench is generated by its internal torque release structure, which is composed of three structures: pressure spring, torque release joint, and torque top rod. After the torque wrench emits a "click" sound, it prompts to reach the torque value you require. Usage of torque wrench: When using a torque wrench, it is appropriate to hear a "snap" sound; In the use of a torque wrench, the first step is to select the appropriate range according to the requirements of the measuring component. The measured torque value should not be less than 20% of the range of the torque wrench in use. A range that is too large should not be used for reinforcing small torque components, and a torque wrench with a small range should not be used beyond the range; When using a torque wrench, first connect the stressed pawl to auxiliary accessories (such as sleeves and various nozzles) to ensure that the connection is no longer a problem
在加固扭力之前,設定好需要加固的力值,并鎖好緊鎖裝置,然后調(diào)整好方向轉(zhuǎn)換鈕到加力的方向；測量時,手要把握住把手的有效范圍,沿垂直於管身方向慢慢地加力直聽到到達已設定的量值后發(fā)出的聲音.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超過10度。其水平方向上下偏差不應超過3度,我廠在使用過程中操作人員應保證其上下左右施力范圍均不超過15度；為了不使測量結(jié)果因水平和垂直方向上的偏差而產(chǎn)生影響,在測量時,應在加力把持端上施加一個垂直向下的穩(wěn)定力值注：
Before strengthening the torque, set the force value to be strengthened, lock the locking device, and then adjust the direction switch button to the direction of force application; When measuring, the hand should hold the effective range of the handle and slowly apply force perpendicular to the pipe body until the sound is heard after reaching the set value. During the force application process, according to the national standard instrument operating specifications, the verticality deviation should not exceed 10 degrees. The horizontal deviation should not exceed 3 degrees, and our factory's operators should ensure that the range of force application from top to bottom, left and right does not exceed 15 degrees during use; In order to prevent the measurement results from being affected by deviations in the horizontal and vertical directions, a vertically downward stable force value should be applied to the force application control end during measurement. Note:
1.用途:扭力扳手為旋轉(zhuǎn)螺栓或螺帽的工具。
1. Purpose: A torque wrench is a tool for rotating bolts or nuts.
2.用法:扭力扳手扳轉(zhuǎn)時應該使用拉力，推轉(zhuǎn)扳手極易發(fā)生危險。3.扭力扳可用于松緊螺栓，螺栓旋緊前應先將螺栓清潔并上潤滑油。4.使用扭力扳手旋緊螺栓時應均勻使力，不得利用沖擊力。后一個要注意的，大規(guī)格扭矩扳手使用時，可外加接長套桿以便操作省力，如長期不用，調(diào)節(jié)標尺刻線退扭矩小數(shù)值處有許多人問到扭力扳手究竟哪種質(zhì)材會好些。
2. Usage: When turning a torque wrench, tension should be used, as pushing the wrench can easily cause danger. 3. The torque wrench can be used to tighten bolts. Before tightening the bolts, they should be cleaned and lubricated. 4. When using a torque wrench to tighten bolts, the force should be evenly applied and impact force should not be used. The last thing to note is that when using a large-sized torque wrench, a lengthening sleeve can be added for easy operation. If not used for a long time, adjust the scale line back to the small torque value. Many people have asked which material would be better for a torque wrench.
