Working Principle Of Torque Wrench

The principle of a torque wrench (torque wrench) making a kata sound is simple,and can be divided into the following steps to understand:

1.After the torque wrench emits the sound of "Kata",it indicates that the torque value you have reached has been reached.

2.The "cat" issued by the torque wrench is generated by the internal torque release structure,which is divided into three structures: pressure spring,torque release joint,and torque jack.

3.First set the required torque value on the torque wrench (the spring sleeve is placed on the top rod to apply pressure to the torque release joint),lock the torque wrench,and start tightening the bolts.When the bolt reaches the torque value (when the torsion force is greater than the pressure of the spring),there will be an instantaneous disconnection effect.At the moment when the disconnection effect occurs,the joint hits,and the "cata" sound emitted by the metal shell of the wrench.This confirms the reminder effect of reaching the torque value (in fact,it is like the principle that our arm joints are bent at 15 degrees and placed in the iron pipe and will encounter the steel pipe after straightening).
