电动扭力扳手结构及工作特点介绍

电动扭力扳手,也叫扭力扳手或力矩扳手,力矩就是力和距离的乘积,在紧固螺丝螺栓螺母等螺纹紧固件时需要控制施加的力矩大小,以保证螺纹紧固且不于因力矩过大破坏螺纹,所以用电动扭力扳手来操作。设定好一个需要的扭矩值上限,当施加的扭矩达到设定值时,扳手会发出“卡塔”声响或者扳手连接处折弯一点角度,这就代表已经紧固不要再加力了。

Electric torque wrench, also known as torque wrench or torque wrench, torque is the product of force and distance. When tightening threaded fasteners such as screws, bolts, and nuts, it is necessary to control the amount of torque applied to ensure that the threads are tightened and not damaged due to excessive torque. Therefore, electric torque wrench is used for operation. Firstly, set a required upper limit for the torque value. When the applied torque reaches the set value, the wrench will make a "snap" sound or bend the wrench connection at a slight angle, indicating that it has been tightened and no further force is needed.
电动扭力扳手是在发电厂电力检测及各工业行业生产检修安装现场,紧固和拆卸大直径螺栓螺母相当困难,尤其在操作人员难以施工的环境中(如设备周围空间较小,无法使用加力杆及各类特种扳手等),综合国内外技术研制成功力矩放大扳手,可帮您从根本上这一难题。力矩放大器、力矩倍增器、反力臂支爪(反作用脚)套筒扳头组成,操作人员只需施加很小的力,即可得到4-70倍的输出力矩,从而轻捷的完成螺栓螺母的紧固拆卸工作。其特点是采用行星变速机构作为主传动,体积小,重量轻,由于变速比大,输入较小力量就能产生很大的输出扭矩。产品选用合金钢和精良的热处理工艺,坚固耐用。广泛用于各种型号的螺栓螺母的紧固拆卸工作。电动扭力扳手主要应用于钢结构钢架吊装高强度螺栓的紧固,曾在电力建设、桥梁建设、高层建筑、冶金化工等钢结构安装行业广泛应用
Electric torque wrenches are used in power plant inspection and various industrial production and maintenance installation sites. It is quite difficult to tighten and disassemble large diameter bolts and nuts, especially in environments where operators are difficult to construct (such as small equipment surrounding space, unable to use force rods and various special wrenches, etc.). Based on advanced domestic and foreign technologies, a torque amplification wrench has been successfully developed, which can help you fundamentally solve this problem. The torque amplifier, torque multiplier, and reaction arm support claw (reaction foot) sleeve wrench are composed. The operator only needs to apply a small force to obtain 4-70 times the output torque, thus easily completing the tightening and dismantling work of bolts and nuts. Its characteristic is the use of an efficient planetary transmission mechanism as the main transmission, which is small in size and light in weight. Due to the large transmission ratio, a small input force can generate a large output torque. The product is made of high-grade alloy steel and advanced heat treatment technology, which is sturdy and durable. Widely used for fastening and dismantling various types of bolts and nuts. Electric torque wrenches are mainly used for fastening high-strength bolts in the hoisting of steel structures and steel frames. They have been widely used in steel structure installation industries such as power construction, bridge construction, high-rise buildings, metallurgy and chemical engineering
扭剪电动扳手
扭距扳手发出卡塔声音的原理很简单的.可以分为以下几个步骤去理解
The principle of the torque wrench making a clicking sound is very simple. It can be understood in the following steps
1,扭距扳手在发出"卡塔"声后是提示以达到你要求的扭距值了
1. After the torque wrench emits a "click" sound, it prompts to reach the torque value you require
2,扭距扳手所发出的"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" emitted by the torque wrench is generated by its internal torque release structure, which is composed of three structures: pressure spring, torque release joint, and torque top rod
3,在扭距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
3. Firstly, set the required torque value on the torque wrench (pressure is applied to the torque release joint by the spring sleeve on the top rod), lock the torque wrench and start tightening the bolt. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), an instantaneous disconnection effect will occur. At the moment of the disconnection effect, a "click" sound will be emitted by the joint hitting the metal shell of the wrench. This confirms the reminder effect of reaching the torque value (Actually, it's just like the principle that when our arm joints are bent at 15 degrees and placed in an iron pipe, they instantly straighten and hit the steel pipe.)
电动扭力扳手(大功率扳手,液压扭力扳手,大功率电动扭力扳手)是帮助您装、拆螺栓、螺母,同时能比较准确的控制拧紧扭矩的理想工具,它广泛适用于冶金、电力、化工、机械、通信等行业的机械设备和设施,重要螺栓联接的安装及拆卸维修,能方便快捷地完成您的装拆螺栓任务,同时可有效地保证您所需的扭矩值。
Electric torque wrenches (high-power wrenches, hydraulic torque wrenches, high-power electric torque wrenches) are ideal tools to help you install and remove bolts and nuts, and to accurately control tightening torque. They are widely used in mechanical equipment and facilities in industries such as metallurgy, electricity, chemical engineering, machinery, communication, etc. The installation, disassembly, and maintenance of important bolt connections can facilitate and quickly complete your bolt installation and disassembly tasks, At the same time, it can effectively ensure the torque value you need.
