折叠式高强螺栓数显扭矩扳手设计

Design on a Folding Digital Torque Wrench Working on High Strength Bolt

针对高强螺栓的装拆、紧固劳动强度大,且拧紧力矩难以控制的情况,设计了一种可折叠的便携式高强螺栓扳手,能实时显示当前拧紧力矩,并且能根据设定力矩自动报警。该扳手采用电池供电,采用AT89S51芯片作为微处理器,结构小巧、使用方便、能够精确控制输出力矩,具有广泛的市场应用前景。

With respect to high work intensity in screwing or unscrewing high strength bolts and the uncontrollable bolt tightening torque,a folding digital torque wrench is designed which can display tightening torque immediately and give an alarm according to preset value.The wrench can control working torque accurately with small structure and portability through using battery and AT89S51 microprocessor.It will be applied to engineering widely.
