定扭矩电动扳手是“电”驱动的扳手,是指拧紧和拆卸螺栓螺母的电动工具,是拧紧高强度螺栓的工具。用于钢桥、厂房、化工、发电设备安装用大六角头高强度螺栓的初拧和终拧,扭剪型高强度螺栓的初拧,以及对螺栓紧固件扭矩或轴向力有严格要求的地方。结构方面,定扭矩电动扳手有两种:安全离合式和冲击式。

Constant torque electric wrench is an "electric" driven wrench, which refers to an electric tool for tightening and removing bolts and nuts, and a tool for tightening high-strength bolts. It is used for the initial and final tightening of large hexagon head high-strength bolts for the installation of steel bridges, plants, chemical industry and power generation equipment, the initial tightening of torsion shear high-strength bolts, and places where there are strict requirements on the torque or axial force of bolt fasteners. In terms of structure, there are two kinds of constant torque electric wrenches: safety clutch type and impact type.
根据电源的不同,定扭矩电动扳手可分为带电池的电动扳手和220伏电源的电动扳手。
According to different power supplies, the constant torque electric wrench can be divided into electric wrench with battery and electric wrench with 220 V power supply.
其中,带电池的电动扳手体积小、重量轻、使用方便,但扭矩较小,一般用于驱动普通螺丝。220V电源的定扭矩电动扳手比电池的定扭矩电动扳手更重更大,主要是扭矩大,可以紧固高强度螺栓。
Among them, the electric wrench with battery has the advantages of small volume, light weight and convenient use, but the torque is small. It is generally used to drive ordinary screws. The constant torque electric wrench of 220V power supply is heavier and larger than the constant torque electric wrench of battery. The main reason is that the torque is large and can fasten high-strength bolts.
定扭矩电动扳手是一种常见的恒扭矩电动扳手,主要用于刚开始拧紧螺栓。它的使用非常简单,就是对准螺栓,转动电源开关就可以了。
Constant torque electric wrench is a common constant torque electric wrench, which is mainly used to tighten bolts at the beginning. Its use is very simple, that is, align the bolt and turn the power switch.
定扭矩电动扳手主要用于拧紧扭矩剪切高强度螺栓。它的用途是将扳手套筒与螺栓Torx头对准,转动电源开关,直到扭力剪切高强度螺栓的Torx头断裂。常见的电动扳手有枪型和角型。
扭剪扳手
Constant torque electric wrench is mainly used to tighten torque shear high-strength bolts. Its purpose is to align the wrench socket with the Torx head of the bolt and turn the power switch until the Torx head of the high-strength bolt is broken. Common electric wrenches are gun type and angle type.
具有固定扭矩的电动扳手可以初始拧紧和更终拧紧。它用于先调节扭矩,然后拧紧螺栓。常见的定扭矩电动扳手也有枪型和角型。
The electric wrench with fixed torque can be used for initial tightening and final tightening. It is used to adjust the torque first and then tighten the bolts. Common constant torque electric wrenches also have gun type and angle type.
定扭矩电动扳手施工现场安全注意事项:
Safety precautions for construction site of constant torque electric wrench:
在打开电源之前,有必要在插入开关之前检查开关是否关闭。
Before turning on the power supply, it is necessary to check whether the switch is off before inserting the switch.
确认与现场连接的电源是否与恒扭矩电动扳手要求的电压一致,是否有漏电保护器。
Confirm whether the power supply connected to the site is consistent with the voltage required by the constant torque electric wrench and whether there is a leakage protector.
根据螺母的尺寸选择匹配的套筒,并正确安装。
Select the matching sleeve according to the size of the nut and install it correctly.
不应使用过高或过低的电压。
Too high or too low voltage should not be used.
不要将简化的气缸用作锤击工具。
Do not use a simplified cylinder as a hammering tool.
不要在手摇杆上加套杆或撬杆施力。
Do not add a sleeve bar or crowbar on the hand lever to apply force.
电动扳手的金属外壳需要可靠接地。
The metal shell of the electric wrench needs to be reliably grounded.
检查定扭矩电动扳手本体安装螺钉的紧固情况。如果发现螺钉松动,需要立即重新拧紧。
Check the fastening of the mounting screws of the fixed torque electric wrench body. If the screws are found to be loose, they need to be retightened immediately.
检查电动扳手两侧手柄是否完好,安装是否牢固。
Check whether the handles on both sides of the electric wrench are intact and firmly installed.
站在梯子上或在高处作业时,应采取措施防止从高处坠落。
When standing on a ladder or working at heights, measures shall be taken to prevent falling from heights.
如果工作场所距离电源较远,需要延长电缆时,必须使用容量足够、安装合格的延长电缆。
If the workplace is far away from the power supply and an extension cable is required, an extension cable with sufficient capacity and qualified installation must be used.
