The working principle of torque wrench


Release Time:

Feb 26,2020

The principle of the torque wrench (torque wrench) making a kata sound is very simple, which can be divided into the following steps to understand: 1. After the torque wrench makes a "kata" sound, it indicates that the torque value you require has been reached; 2. The "kata" issued by the torque wrench is generated by the torque release structure inside itself, its structure is divided into three structures: pressure spring, torque release joint and torque push rod. 3. First, set the required torque value on the torque wrench (the spring is set on the ejector rod to press the torque release joint), 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)

The principle of the torque wrench (torque wrench) making a kata sound is very simple and can be divided into the following steps to understand:
1. After the torque wrench makes a "kata" sound, it indicates that the torque value you require has been reached;
2. The "kata" issued by the torque wrench is produced by its own internal torque release structure, and its structure is divided into three structures: pressure spring, torque release joint, and torque ejector rod.
3. First, set the required torque value on the torque wrench (the spring is set on the ejector rod to press the torque release joint), 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), it will produce a momentary disjoint effect. At the moment of disjoint effect, the joint knocks and the "carta" sound emitted by the metal shell of the wrench. From this, we can confirm the reminding effect of reaching the torque value (in fact, it is the same as the principle that our arm joint will touch the steel pipe after being bent at 15 degrees and placed in the iron pipe for an instant straightening).
