手动扭矩扳手正确使用方法有哪些 扭矩扳手也叫做力矩扳手， 下面 介绍音晌式扭矩扳手使用注意事项： (1)设定所需的扭矩值，并将锁紧装置拨至 lock 位置。 (2)请从小值往大值方向调整扭矩，若超过设定值，请往回调至低于设定扭 矩值后再调。 (3)请勿直接从大值调至小值。 (4)检查扭矩扳手驱动头是否适合，或选用合适的转接头。扭力扳手的用法（1）所选用的扭力扳手的开口尺寸一定要与螺栓或螺母的尺寸相符合，扳手开口过大易滑脱并损伤螺件的六角，在进口汽车维修中，应注意扳手公英制的选择。 (5)施力前需确定扳手与被施力的物体确实结合。 (6)施力位置为握把正。 (7)施力应平稳缓慢，听到音响(即待弹簧释放)后，即停止施力。 (8）使用后需将设定值转回小刻划。 (9)使用大扭矩扳手时，操作者需注意身体。

What are the correct ways to use manual torque wrenches? Torque wrenches are also called torque wrenches. Here are the precautions for the use of sound torque wrenches: (1) set the required torque value and turn the locking device to the lock position. (2) Please adjust the torque from small value to large value. If it exceeds the set value, please adjust it back to lower than the set torque value before adjustment. (3) Do not directly adjust from large value to small value. (4) Check whether the driving head of the torque wrench is suitable, or select a suitable adapter. Usage of torque wrench (1) the opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip off and damage the hexagon of the screw. In the maintenance of imported vehicles, attention should be paid to the selection of metric and inch system of the wrench. (5) Before applying the force, it is necessary to make sure that the wrench is indeed combined with the object to be applied. (6) The force application position is the center of the grip. (7) The force shall be applied steadily and slowly. After hearing the sound (i.e. waiting for the spring to release), the force shall be stopped. (8) After use, it is necessary to turn the set value back to the small score. (9) When using a large torque wrench, the operator should pay attention to his body.

Calibration method of torsion shear wrench

4、检查中点，高点数值是否准确。

4. Check whether the midpoint and high point values are accurate.

调整轮加4圈即40Nm，此时扭力扳手应为60Nm，通过看检定仪数据看扭力扳手数值是否准确，继续操作调整轮顺时针拧4圈，到100Nm，查看数值，进行微调。

Add 4 turns to the adjusting wheel, i.e. 40nm. At this time, the torque wrench should be 60NM. Check whether the torque wrench value is accurate by looking at the data of the calibrator. Continue to operate the adjusting wheel, turn it clockwise for 4 turns to 100nm, check the value, and make fine adjustment.

5、回低点，调整轮对齐零点，拨动标尺。

5. Return to the low point, adjust the wheel to align the zero point, and move the ruler.

调整轮相应减8圈，如检定仪数据准确，为20Nm，满足±4%的误差，拿掉调整轮，用调整轮0刻度位置对准低点，并拨动标尺至20Nm位置，上紧扭紧手柄，装上螺纹挡销，校验孔贴上校验标志。

Adjust the wheel by 8 turns. If the data of the calibrator is accurate, it is 20nm, meeting the error of ± 4%, remove the adjusting wheel, align the low point with the 0 scale position of the adjusting wheel, move the scale to the position of 20nm, tighten the handle, install the threaded retaining pin, and paste the calibration mark on the calibration hole.
