  扭矩扳手又叫力矩扳手、扭力扳手、扭矩可调扳手,是扳手的一种,一般分为三类:手动力矩扳手、气动扭力扳手和电动力矩扳手。定扭扳手广泛用于对拧紧工艺有严格要求的装配线,使产品各个紧固件扭矩值一致,生产出来的产品质量有保障。

  Torque wrench, also known as torque wrench, torque wrench, torque adjustable wrench, is a kind of wrench, generally divided into three categories: hand power moment wrench, pneumatic torque wrench and electric torque wrench. Fixed-twist wrench is widely used in assembly line which has strict requirements for tightening process, so that the torque values of each fastener of the product are consistent, and the quality of the products produced is guaranteed.
  扭矩扳手(扭力扳手)发出卡塔声音的原理很简单,可以分为以下几个步骤去理解:
  The principle of the torque wrench (torque wrench) to emit the CATA sound is very simple. It can be understood in the following steps:
  1、扭矩扳手在发出“卡塔”声后是提示已达到你要求的扭矩值了;2、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.
  1. Torque wrench is prompted to reach the required torque value after it emits the "kata" sound. 2. The "kata" 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 ejector rod.
  3、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。由此来确认达到扭矩值的提醒作用(其实就象我们手臂关节成15度弯曲放在铁管里瞬间申直后会碰到钢管的原理一样)。
  3. Firstly, the required torque value is set on the torque wrench (pressure is released from the joint by the spring sleeve on the ejector rod), the torque wrench is locked, and the bolt is tightened. When the bolt reaches the value of torque (when the use of torque is greater than the spring pressure), it will produce the effect of instantaneous disconnection. At the moment of disjointing effect, it emits joint tapping and "kata" sound from wrench metal shell. This confirms the reminder effect of reaching the torque value (in fact, it's just like the principle that when we bend our arm joints 15 degrees in the iron pipe and straighten it instantly, we will meet the steel pipe).
  以上所说是比较常用的手动扭力扳手,除此之外还有电动扭力扳手、风动扭力扳手等。
  Above is the most commonly used manual torque wrench, in addition to electric torque wrench, pneumatic torque wrench and so on.
  现阶段分为机械音响报警式,数显式,指针式(表盘式),打滑式(自滑转式).其中机械音响报警式,采用杠杆原理,当力矩到达设定力矩时会出现"嘭扭矩扳手"机械相碰的声音,此后扳手会成为一个死角,及相当于呆扳手,如再用力,会出现过力现象.

  At present, it is divided into mechanical sound alarm type, digital display type, pointer type (dial type), sliding type (self-sliding type). Among them, mechanical sound alarm type adopts lever principle, when the moment reaches the set moment, there will be the sound of mechanical collision of "thumping torque wrench". Thereafter, the wrench will become a dead angle and equivalent to a dull wrench, if used again, there will be over-force phenomenon.
  数显式和指针式(表盘式)差不多,都是把作用力矩可视化.现阶段的数显和指针都是在机械音响报警式扭矩扳手的基础上工作的.
  Digital display and pointer (dial type) are similar in that they visualize the moment of action. At present, both digital display and pointer work on the basis of mechanical sound alarm torque wrench.
  打滑式(自滑转式)采用过载保护、自动卸力模式,当力矩到达设定力矩时会自动卸力(同时也会出现机械相碰的声音),此后扳手自动复位,如再用力,会再次打滑,不会出现过力现象.此种是比较近1,2年才出现的新感念产品.
  Sliding type (self-slipping type) adopts overload protection and automatic unloading mode. When the moment reaches the set moment, it will unload automatically (and there will also be the sound of mechanical collision). After that, the wrench will automatically reset. If the wrench is used again, it will slip again, and there will be no over-force phenomenon. This is a new concept product which has only appeared in the last 1 or 2 years.
  机械音响报警式是目前市场的主流产品,主要体现在价格便宜,其它3种相对来说,价格昂贵.不过由于各行各业对这方面要求越来越高,以及效率的要求,数显式、指针式(表盘式)及打滑式(自滑转式)的需求会越来越高.
  Mechanical audio alarm is the mainstream product in the market, mainly reflected in the low price, the other three are relatively expensive. However, due to the increasingly high demand for this aspect and efficiency in all walks of life, the demand for digital display, pointer type (dial type) and sliding type (self-sliding type) will become higher and higher.
