Talk About The Technical Operation Of Torque Wrench

With the advancement of technology and the rapid development of the industry,the use of torque wrenches is becoming more and more common.For example,the traditional torque wrench has evolved into a set ratchet torque wrench,a digital display torque wrench,a preset torque wrench,etc.,Although the categories will be different,their principles are roughly the same.

The following is divided into three steps to explain:

1.First set the required torque value on the wrench (the spring is sleeved on the top rod to apply pressure to the torque release joint),lock the torque wrench and start to tighten the bolt,when the bolt reaches the torque value (when the torque is greater than After the pressure of the spring),there will be an instantaneous disconnection effect.At the moment when the disconnection effect occurs,a "cata" sound made by the joint hitting the metal shell of the wrench is emitted.This confirms the reminder effect of reaching the torque value.(In fact,it's like the principle that our arm joints are bent at 15 degrees and placed in an iron pipe,and they will hit the steel pipe after being straightened.)

2.The "cat" issued by the torque wrench is generated by the internal torque release structure.The structure is divided into three structures: pressure spring,torque release joint,and torque jack.3.The torque wrench is issued Behind the sound of "Kata" is a prompt to achieve the torque value you require.

Understand the above principle,let's talk about the technical operation of the torque wrench,the wrench is used in this way:

1.When using a torque wrench,it is appropriate to hear a "pop" sound at this time.

2.In the use of torque wrenches,first select a moderate range according to the requirements of the measuring parts.The measured torque value should not be less than 20% of the range of the torquer in use.Reinforced,the small range of torque can not be used over-range.

3.When using a torque wrench,first connect the stress pawl to auxiliary accessories (such as sleeves,various types of mouths) to ensure that the connection is no problem.Before strengthening the torque,set the force value that needs to be strengthened Lock the locking device,and then adjust the direction switch to the direction of force.
