扭力扳手为什么发出卡塔的声音?

大家都用过扭力扳手,使用时它发出卡塔声音后是提示已达到你要求的扭矩值了。下面咱们小编讲解一下电动扭力扳手的内部结构:

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:
扭矩扳手所发出的“卡塔”是由本身内部的扭矩释放结构产生的,其结构分为压力弹簧、扭矩释放关节、扭矩顶杆三结构所组成。首先在扭矩扳手上设定所需扭矩值(由弹簧套在顶杆上向扭矩释放关节施压),锁定扭矩扳手,开始拧紧螺栓。当螺栓达到扭矩值(当使用扭力大于弹簧的压力)后,会产生瞬间脱节的效应。在产生脱节效应的瞬间发出关节敲击,扳手金属外壳所发出的“卡塔”声。
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.
电动扭力扳手
扭力扳手也叫扭矩扳手,力矩就是力和距离的乘积,在紧固螺丝螺栓螺母等螺纹紧固件时需要控制施加的力矩大小,以保证螺纹紧固且不至于因力矩过大破坏螺纹,所以用扭矩扳手来操作。
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.
首先设定好一个需要的扭矩值上限,当施加的扭矩达到设定值时,扳手会发出“卡塔”声响或者扳手连接处折弯一点角度,这就代表已经紧固不要再加力了。
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、设定扭矩后,将套筒插入方形驱动头。
1. After setting the torque, insert the sleeve into the square drive head.
2、将套筒套在螺栓头部或螺母上。
2. Put the sleeve over the bolt head or nut.
3、将扭力扳手向右转动进行紧固。
3. Tighten the torque wrench by turning it to the right.
4、听到“咔嗒”声后,紧固结束。
4. After hearing the "click", the fastening is completed.
扭力板手使用注意事项
Precautions for use of torque wrench
施加扭矩时,手握在扭矩扳手手柄中间刻度线位置。方头与套筒、螺母稳固连接。只能在所知扳手标注的方向上施力,同时施力方向应在正负15度内。
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.
