扭力扳手规格型号、分类及使用方法

来源:https://www.xjnwz.com 日期:2021-09-29 发布人:admin

扭力扳手通常也叫做扭矩扳手,属于扳手的一种,通常分为电动力矩扳手和手动力矩扳手两种。力矩就是力与距离的乘积,在紧固螺丝、螺栓和螺母等紧固件时需要控制施加的力矩大小,以确保螺纹的紧固还不至于因力矩过大把螺纹破坏了,因此用扭力扳手去操作。那么具体的扭力扳手规格型号都有哪些呢?

Torque wrench, also known as torque wrench, is a kind of wrench, which is usually divided into electric torque wrench and manual torque wrench. Torque is the product of force and distance. When tightening screws, bolts, nuts and other fasteners, it is necessary to control the applied torque to ensure that the thread will not be damaged due to excessive torque. Therefore, use a torque wrench to operate. So what are the specific specifications and models of torque wrench?
扭力扳手规格型号
Specification and model of torque wrench
扭力扳手的型号一般是按照它的扭力范围来定的,比如WEC4-340AN:表示大扭力值是。340N。m。方榫尺寸是一样的,有1/4"、3/8"、1/2"、3/4"等,还有分数显的和机械式。扭力扳手规格量程一般是1-5N,5-25N,10-50N,20-100N,40-200N,70-350N。扭力扳手有很多的品牌,不同品牌的扭力扳手,其规格型号也是有所不同的。
The model of torque wrench is generally determined according to its torque range. For example, wec4-340an: indicates that the large torque value is. 340N。 m。 The size of square tenon is the same, including 1 / 4 ", 3 / 8", 1 / 2 ", 3 / 4", etc., as well as fractional and mechanical. The specification range of torque wrench is generally 1-5n, 5-25n, 10-50n, 20-100n, 40-200n and 70-350n. There are many brands of torque wrenches. The specifications and models of torque wrenches of different brands are also different.
扭力扳手的分类:
Classification of torque wrenches:
根据扭力仪器的显示方式和工作原理,扭力仪器共分为三大类:
According to the display mode and working principle of torque instruments, torque instruments are divided into three categories:
1、扭力表
1. Torque meter
依据力的反作用性,通过外部对其测力点施加扭矩,带动仪器内部已经施加了一定负荷的杠杆机构,传动机械齿轮使表盘上的指针在外部施加的力的作用下进行有规律的转动,从而显示出现有的扭矩值
According to the reaction of the force, the external torque is applied to the force measuring point to drive the lever mechanism with a certain load inside the instrument, and drive the mechanical gear to make the pointer on the dial rotate regularly under the action of the external force, so as to display the existing torque value
2、扭力批
2. Torque screwdriver
扭力批也称扭力起子。根据力的特性,采用负向施加力的动作,当外部施加的扭力达到一个已经设置好的数值且等於内部设定力值时,内部跳档机构动作,并且能听到啼嗒的声响时,表示已达到预设值。
Torque screwdriver is also called torque screwdriver. According to the characteristics of the force, the action of applying force in the negative direction is adopted. When the externally applied torque reaches a set value and is equal to the internal set force value, the internal skip mechanism acts and the sound of clicking can be heard, indicating that the preset value has been reached.
3、扭力扳手
3. Torque wrench
也称扭力扳子,原理与扭力批近似。采用杠杆原理与跳档机构并用,当外部施加的扭矩大於内部设定的力值时,内部跳档机构动作且卸力,表示已经达到预设的力值,同时可以听到由跳档产生的声响。
Also known as torque wrench, its principle is similar to that of torque batch. The lever principle is used in combination with the skip mechanism. When the externally applied torque is greater than the internally set force value, the internal skip mechanism acts and releases the force, indicating that the preset force value has been reached, and the sound generated by the skip can be heard at the same time.
扭力扳手的使用方法
Usage of torque wrench
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 a torque wrench, first connect the stressed pawl with auxiliary accessories (such as sleeve and various nozzles) to ensure that there is no problem with the connection. Before tightening the torsional force, set the force that needs to be reinforced, lock the locking device, and adjust the direction switch button to the direction of the additional force.
扭力扳手规格型号的相关内容就为大家介绍到这里了,扭力扳手扳手其实就是用来紧固螺栓的,因而扭力扳手在许多行业都有应用,而我们经常会在汽车维修的时候见到这个工具,有了这个工具维修人员的工作效率就得到了提高。
The specification and model of torque wrench are introduced here. Torque wrench is actually used to fasten bolts. Therefore, torque wrench is used in many industries, and we often see this tool during automobile maintenance. With this tool, the work efficiency of maintenance personnel is improved.
