可调式扭力扳手也叫预置式扭矩扳手,这款扳手具有预设扭矩数值和声响报警的特点,操作起来也是比较简单的,例如螺栓只需要拧10N.m的力,直接在扳手上设置,到达预设数值时,“喀嚓”声响报警,停止用力即可,操作完成。

Adjustable torque wrench is also known as preset torque wrench. This wrench has the characteristics of preset torque value and sound alarm, and it is relatively simple to operate. For example, the bolt only needs to be screwed by 10N. M, and it can be set directly on the wrench. When the preset value is reached, the "click" sound alarm will sound, and the operation can be completed.
可调式扭力扳手组成及原理:
Composition and principle of adjustable torque wrench:
可调式扭力扳手一种以高压气泵为动力源的扭矩扳手。是由一个或两个有力的气动马达来驱动带有三层或更多周转齿轮的扭矩倍增器。 经由调整气体压力来控制扭矩大小,为允许特定的扭矩需求设定,每台工具都配有专用的气压先对扭矩的对照图表和校正报告。且为能更进一步的应用,气动扭矩扳手可同时搭配扭矩传感器,时输出的扭矩更。在获得所需的扭矩后可使用合适的回路系统以手动或自动来关闭气源。
The adjustable torque wrench is a torque wrench with high pressure air pump as power source. A torque multiplier with three or more epicyclic gears is driven by one or two powerful pneumatic motors. The torque is controlled by adjusting the gas pressure. In order to allow the specific torque demand setting, each tool is equipped with a special air pressure, and the torque comparison chart and calibration report are provided. For further application, pneumatic torque wrench can be combined with torque sensor at the same time, and the output torque is more. After the required torque is obtained, the air source can be closed manually or automatically by using a suitable loop system.
可调式扭力扳手是由两部分组成的,扳手杆和可换头。在下图中我们可以看到只要确定扳手方隼的尺寸,就可以更换各式各样的头部,极大的拓宽了扭力扳手的工位需求。
扭剪扳手
Adjustable torque wrench is composed of two parts, wrench rod and replaceable head. In the figure below, we can see that as long as the size of the wrench square falcon is determined, all kinds of heads can be replaced, which greatly widens the working position requirements of torque wrench.
可调式扭力扳手特点:

6. Three working modes (peak value, tracking and preset) are switched.
7、任意报警值设置声光报警。
7. Set sound and light alarm for any alarm value.
8、背光显示,有按键或有较大值变化会亮背光,无操作20秒自动关闭。
8. Backlight display: the backlight will be on if there is a key or a large value change, and it will be turned off automatically after 20 seconds without operation.
可调式扭力扳手是属于高精密仪器的,有一些事项还是要注意下:
Adjustable torque wrench belongs to high precision instrument. There are some matters needing attention:
1、使用中请勿强烈冲击。
1. Please do not make strong impact during use.
2、不能当榔头使用,敲击工件。
2. Can not be used as a hammer, knock the workpiece.
3、扳手报警后请勿继续施力。
3. Do not continue to apply force after the wrench alarm.
4、使用前请检查扳手上的箭头是否同施力方向一致,如果不一致请将扳手头旋转180度重新安装。
4. Before use, please check whether the arrow on the wrench is consistent with the force application direction. If not, please rotate the wrench head 180 degrees to install again.
5、请勿自行拆卸扳手各部件,以免破坏精度影响使用。
5. Do not disassemble the parts of the wrench by yourself, so as to avoid damaging the accuracy and affecting the use.
6、预置式扭力扳手,使用完后,应把扭力值调至零位放置,以保持扳手精度,延长使用寿命。
6. After using the preset torque wrench, the torque value should be adjusted to zero position to maintain the accuracy of the wrench and prolong its service life.
