扭力扳手原理及使用

来源:https://www.xjnwz.com 日期:2021-07-28 发布人:admin

下面分三个步骤去说明:

There are three steps to explain:
1、首先在扭力扳手上设定所需扭距值(由弹簧套在顶杆上向扭距释放关节施压),锁定扭距扳手开始拧紧螺栓,当螺栓达到扭距值后(当使用扭力大于弹簧的压力后)会产生瞬间脱节的效应.在产生脱节效应的瞬间发出关节敲击扳手金属外壳所发出的"卡塔"声.由此来确认达到扭距值的提醒作用.(其实就象我们手臂关节成15度弯曲放在铁管里瞬间申直后会碰到钢管的原理一样).
1. First, set the required torque value on the torque wrench (press the torque release joint with the spring sleeve on the ejector rod), lock the torque wrench and start tightening the bolts, When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), it will produce an instantaneous disconnection effect. At the moment of the disconnection effect, it will make a "click" sound from the joint knocking on the metal shell of the wrench, so as to confirm the reminder 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 instant straightening)
2、扭力扳手所发出的"卡塔"是由本身内部的扭距释放结构产生的,其结构分为压力弹簧,扭距释放关节,扭距顶杆三结构所组成.
2. The "jam" sent by the torque wrench is generated by its internal torque release structure, which is divided into three structures: pressure spring, torque release joint and torque ejector rod
3、扭力扳手在发出"卡塔"声后是提示以达到你要求的扭距值了.
3. The torque wrench is prompted to reach the torque value you require after making a "lata" sound
对上述原理有所了解,下面谈谈扭力扳手的技术操作,扭力扳手就是这样使用的:
With some understanding of the above principles, let's talk about the technical operation of torque wrench, which is used in this way:
1、扭力扳手使用时,当听到“啪”的一声时,此时是合适的
1. When the torque wrench is used, it is appropriate to hear a "snap" sound
2、在扭力扳手的使用中,首先要根据测量部品的要求选取适中量程,所测扭力值不可小於扭力器在使用中量程的百分之二十,太大的量程不宜用於小扭力部品的加固,小量程的扭力器更不可以超量程使用
2. In the use of torque wrench, first select a moderate range according to the requirements of measuring parts. 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
3、在使用扭力扳手时,先将受力棘爪连接好辅助配件(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,然后调整好方向转换钮到加力的方向
3. When using the torque wrench, connect the force pawl to the auxiliary parts (such as sleeve and all kinds of mouths) to ensure that the connection is fine. Before setting up the torque, set the force value that needs to be reinforced, lock the locking device and adjust the direction switch button to the direction of the additional force.
4、测量时,手要把握住把手的有效范围,沿垂直於管身方向慢慢地加力直至听到到达已设定的量值后发出的声音.在施力过程中,按照国家标準仪器操作规范,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,我厂在使用过程中操作人员应保证其上下左右施力范围均不超过15度
4. During measurement, hold the effective range of the handle with your hand, and apply force slowly along the direction perpendicular to the pipe body until you hear the sound after reaching the set value. In the process of force application, according to the national standard instrument operation specification, the deviation of perpendicularity shall not exceed 10 degrees. The deviation of water square up and down shall not exceed 3 degrees, During the use of our plant, the operators shall ensure that the upper, lower, left and right force application range does not exceed 15 degrees
5、為了不使测量结果因水平和垂直方向上的偏差而產生影响,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
5. In order not to affect the measurement results due to the deviation in the horizontal and vertical directions, a vertical downward stable force value shall be applied on the force application holding end during measurement
注:
Note:
1.用途:扭力扳手为旋转螺栓或螺帽的工具。
1. Purpose: torque wrench is a tool for rotating bolts or nuts.
2.用法:扭力扳手扳转时应该使用拉力,推转扳手极易发生危险。
2. Usage: tension should be used when turning the torque wrench. Pushing the wrench is very dangerous.
3.扭力扳可用于松紧螺栓,螺栓旋紧前应先将螺栓清洁并上润滑油。
3. The torque wrench can be used to loosen the bolts. The bolts should be cleaned and lubricated before tightening.
4.使用扭力扳手旋紧螺栓时应均匀使力,不得利用冲击力。
4. When tightening bolts with torque wrench, the force shall be uniform, and the impact force shall not be used.
还有 一个要注意的,大规格扭力扳手使用时,可外加接长套杆以便操作省力,如长期不用,调节标尺刻线退至扭矩小数值处
It should also be noted that when a large-size torque wrench is used, an extension sleeve rod can be added to save labor in operation. If it is not used for a long time, adjust the scribed line of the scale to the small value of torque
有许多人问到扭力扳手究竟哪种质材会好些,在这里也想说明一下,首先进口的液压扭力扳手多为高强度钛钢,重型液压扳手也有用高强度钢材的,肯定不会是国产的钢材或钛钢,国产的钢材高强度只有国外的一半。看了这些相信大家都会有所选择了。
Many people asked which kind of material would be better for torque wrenches. I also want to explain here. First, most imported hydraulic torque wrenches are high-strength titanium steel. Heavy hydraulic wrenches also use high-strength steel. It will certainly not be domestic steel or titanium steel. The high-strength of domestic steel is only half of that of foreign countries. After reading these, I believe everyone will have a choice.
