扭力扳手有几种?

How many torque wrenches are there?
常用的扭力扳手一般有三种,分别是手动扭力扳手、电动扭力扳手和气动扭力扳手。下面就让我们来具体看看!
There are generally three types of commonly used torque wrenches, namely, manual torque wrenches, electric torque wrenches and pneumatic torque wrenches. Now let's take a look at it in detail!
一、手动扭力扳手。
1、 Manual torque wrench.
顾名思义,手动扭矩扳手是一种需要手动操作的扭矩扳手。以下是一些常见的手动扭矩扳手。
As the name implies, a manual torque wrench is a torque wrench that requires manual operation. The following are some common manual torque wrenches.
1、机械音响报警式;
1. Mechanical audible alarm type;
这种扭力扳手采用杠杆原理。在使用过程中,当扭矩达到设置的扭矩时,会发出机械碰撞的声音,扳手会变成死角,防止过力。
This torque wrench uses the lever principle. In the process of use, when the torque reaches the set torque, there will be a sound of mechanical collision, and the wrench will become a dead corner to prevent excessive force.
2、数显式&指针式(表盘式);
2. Digital display&pointer type (dial type);
这两种类型的扭力扳手的工作基础都是在机械音响上报警提示,并且可视化作用力矩。
The working basis of these two types of torque wrenches is to give an alarm on the mechanical sound and visualize the acting torque.
3、滑动式(自滑动式);
3. Sliding type (self sliding type);
这种扭手采用过载保护、自动卸载模式。扭矩到达设定扭矩时会自动卸下力量(也会发出机械碰撞的声音),之后扳手会自动复位,再用力时会滑动,避免过力。
The handle adopts overload protection and automatic unloading mode. When the torque reaches the set torque, the force will be automatically removed (and the sound of mechanical collision will also be heard), and then the wrench will automatically reset. When the torque is applied again, it will slide to avoid excessive force.
以上几种手动扭力扳手中,机械音响报警时便宜,使用较多。
Among the above manual torque wrenches, mechanical audible alarm is cheap and used more frequently.
二、电动扭力扳手。
2、 Electric torque wrench.
电动扳手是指能够设定扭矩值的电动扳手。主要分为电流式和动态扭矩传感器式两种。
The electric wrench refers to the electric wrench that can set the torque value. It is mainly divided into current type and dynamic torque sensor type.
1.电流式;
1. Current type;
电流式扭力扳手判断扭矩值的依据是电机拧紧过程中电流值的变化。在使用过程中,扳手达到预定扭力后,马达会立即停止工作。
The current type torque wrench judges the torque value based on the change of current value during the motor tightening process. During use, the motor will stop working immediately after the wrench reaches the predetermined torque.
2、动态扭矩传感器式;
2. Dynamic torque sensor type;
动力扭矩传感器式是在拧紧轴上安装传感器,可以检测扭力值的变化,一定达到预定的扭力,马达就会停止工作。
The power torque sensor is installed on the tightening shaft to detect the change of torque value. The motor will stop working when the predetermined torque is reached.
电动扭力扳手具有精度高、使用寿命长、故障率低等优点,可以在很多领域发挥作用。
The electric torque wrench has the advantages of high precision, long service life, low failure rate, and can play a role in many fields.
三、气动扭力扳手。
3、 Pneumatic torque wrench.
气动扭矩扳手由压缩机中的压缩空气作为空气来源,以此驱动扭力扳手中的启动电机,并让齿轮拧紧螺栓,主要有油压脉冲式、离合器式、动态扭矩传感器式。
The pneumatic torque wrench uses the compressed air in the compressor as the air source to drive the starting motor in the torque wrench and let the gear tighten the bolts, mainly including oil pressure pulse type, clutch type and dynamic torque sensor type.
1、油压脉冲式&离合器式;
1. Oil pressure pulse type&clutch type;
这两种都是通过扭矩值达到设定值后自动断气,避免过度的力。
Both of them automatically cut off air after the torque value reaches the set value to avoid excessive force.
2、动态扭矩传感器式;
2. Dynamic torque sensor type;
扭矩值达到设定值后,控制器控制电磁阀的断气,扳手停止,不能再用力,不能过度用力。
When the torque value reaches the set value, the controller controls the air cutoff of the solenoid valve, and the wrench stops. No more force or excessive force is allowed.
气动扭力扳手中,油压脉冲式因其无反作用力而受到很多人的欢迎,但不适合打软连接螺栓。
Among pneumatic torque wrenches, the oil pressure pulse type is welcomed by many people because of its non reaction force, but it is not suitable for softening the connecting bolts.
