扭矩扳手是汽车维修必不可少的维修工具,那么扭矩扳手怎么使用呢?相信有不少朋友都不知道,那下面我们就来一起看下吧。

Torque wrench is an essential maintenance tool for automobile maintenance. How to use torque wrench? I believe many friends don't know. Let's take a look together.
1、选用合适量程的扭力扳手
1. Select a torque wrench with appropriate range
预置式扭力扳手的使用中,首先要根据测量工件的要求,选取适中量程扭力扳手,所测扭力值不可小于扭力器在使用中量程的百分之二十,太大的量程不宜用于小扭力部品的加固,小量程的扭力器更不可以超量程使用;
In the use of preset torque wrench, first select a torque wrench with moderate range according to the requirements of measuring workpiece. The measured torque value shall not be less than 20% of the range of the torque device in use. Too large range shall not be used for the reinforcement of small torque parts, and the torque device with small range shall not be used beyond the range;
2、根据工件所需扭矩值要求,确定预设扭矩值。
2. Determine the preset torque value according to the required torque value of the workpiece.
预设扭矩值时,将扳手手柄上的锁定环下拉,同时转动手柄,调节标尺主刻度线和微分刻度线数值至所需扭矩值。调节好后,松开锁定环,手柄自动锁定。
When preset the torque value, pull down the locking ring on the wrench handle, turn the handle at the same time, and adjust the values of the main scale line and differential scale line of the scale to the required torque value. After adjustment, release the locking ring and the handle will lock automatically.
3、确认扭力扳手与固定件连接可靠并已锁定
3. Confirm that the torque wrench is reliably connected with the fixed parts and has been locked
用扭力扳手时,先将扳手方榫连接好辅助配件(如套筒,各类批嘴),确保连接已经没问题。在加固扭力之前,设定好需要加固的力值,并锁好紧锁装置,调整好方向转换钮到加力的方向,然后在使用时先快速连续操作5-6次,使扳手内部组件上特殊润滑剂能充分润滑,使扭力扳手更精 确,持 久使用。
When using a torque wrench, first connect the square tenon of the wrench with auxiliary accessories (such as socket and various nozzles) to ensure that the connection is no problem. Before strengthening the torque, set the force value to be strengthened, lock the locking device, adjust the direction conversion button to the direction of force application, and then operate it quickly and continuously for 5-6 times during use, so that the special lubricant on the internal components of the wrench can be fully lubricated, making the torque wrench more accurate and durable.
4、扭力扳手加力方法
4. Torque wrench force application method
在扳手方榫上装上相应规格套筒,并套住紧固件,再在手柄上缓慢用力。施加外力时必须按标明的箭头方向。
Install sockets of corresponding specifications on the square tenon of the wrench, sleeve the fasteners, and then slowly apply force on the handle. The external force must be applied in the direction of the indicated arrow.
手要把握住把手的有用范围,沿垂直于扭力扳手壳体方向,慢慢地加力,直至听到扭力扳手发出“塔”的声音,当拧紧到发出信号“卡嗒”(click)的一声(已达到预设扭矩值),停止加力。一次作业完毕。
Hold the useful range of the handle with your hand, and slowly apply force in the direction perpendicular to the torque wrench housing until you hear the "tower" sound of the torque wrench. When you tighten it to a signal "click" (reaching the preset torque value), stop applying force. One operation is completed.
此时扭力扳手已到达预置扭力值,工件已加力完毕,然后应及时解除作用力,以免损坏另部件。
At this time, the torque wrench has reached the preset torque value and the workpiece has been stressed, and then the force shall be released in time to avoid damaging other parts.
在施力过程中,按照国家标准仪器操作规范,其垂直度偏差左右不应超过10度。其水平方向上下偏差不应超过3度,操作人员在使用过程中应保证其上下左右施力范围均不超过15度。
During the force application, according to the national standard instrument operation specification, the verticality deviation shall not exceed 10 degrees. The horizontal deviation shall not exceed 3 degrees, and the operator shall ensure that the upper, lower, left and right force application range shall not exceed 15 degrees during use.
5、大规格扭矩扳手使用时,可外加接长套杆以便操作省力。
5. When a large-size torque wrench is used, an extension sleeve rod can be added for labor-saving operation.
6、使测量结果因水平和垂直方向上的偏差而产生影响,在测量时,应在加力把持端上施加一个垂直向下的稳定力值,然后再加点力,这样使用值更精准。
6. So that the measurement results will be affected by the deviation in the horizontal and vertical directions. During measurement, a vertical downward stable force value shall be applied on the force application control end, and then a little force shall be added, so that the use value is more accurate.
7、扳手是测量工具,应轻拿轻放,不能代替榔头敲打,不用时请注意将扭力设为小值,存放在干燥处。扭力范围较广,在加固扭力时,相对来讲比较简单,只需要设定其要求扭力值便可进行操作。
7. The wrench is a measuring tool and should be handled with care. It cannot replace the hammer. When not in use, please set the torque to a small value and store it in a dry place. The torque range is wide. It is relatively simple to strengthen the torque. It can be operated only by setting the required torque value.
8、如长期不用,调节标尺刻线退至扭矩小数值处。有利于保证扭矩的精度。
8. If it is not used for a long time, adjust the scale marking to the small value of torque. It is helpful to ensure the accuracy of torque.
