Torque wrench is also called torque wrench, torque wrench, etc. There are many names, but they all refer to type of wrench. Compared to ordinary keys, it is more difficult to use. When locking, control applied torque to ensure that threads are tight and will not be damaged by excessive torque.
The torque wrench has evolved into ratchet torque wrench with setting, digital display type, preset type and other types, but principle is about same.
First set desired torque value on torque wrench and lock torque wrench by applying pressure to connection to remove torque on ejector rod through spring bushing. When tightening bolt, when applied torque exceeds spring pressure, bolt When torque value is reached, there will be a disengagement effect and a "click" sound will be heard when hinge strikes metal body of key, indicating that required torque value has been reached.
In use, it is mainly divided into following steps:
1. Select appropriate range. The measured torque value must not be less than 20% of measurement range of applied torque. The measurement range too large cannot be used to strengthen parts with small torque. Similarly, torque with a small measurement range cannot be used outside measurement range.
2. Preset torque value. Set force to be increased, lock locking device and adjust direction conversion knob in direction of force.
3. Connect accessory accessories and start adding power. Install a proper specification bushing onto square stud of wrench and close fastener Slowly apply force to handle in direction of arrow When you hear “click” sound of torque wrench, it means that set torque has been reached Stop afterburner.
This concludes this article on torque wrench. I hope it expands your understanding of torque wrench and helps you.
