Electric torque wrench is mainly used to tighten bolts in one go. Its use is very simple, that is, pull the power switch onto the bolt. Electric shear wrenches are mainly used to tighten shear type high-strength bolts. Used to pull the power switch towards the bolt until the box head of the shear type high-strength bolt breaks. Torque shear wrenches can be used for initial and final tightening. Used to adjust torque before tightening bolts. The torque shearing wrench is also a constant electric torque shearing wrench. Used to adjust the rotation angle first and then tighten the bolts. Electric angle wrench is an electric wrench specifically used to tighten bolts at the angle of a steel frame, and its purpose is the same as that of an electric torque shearing wrench.

剪切扳手主要用于紧固剪切型高强度螺栓。其目的是破坏剪切型高强度螺栓的梅花头。工作时，将扳手头与螺栓头对齐，拉动开关开始工作。几秒钟后，螺栓箱头会断裂，然后拔出扳手拉动扳机弹出箱头，这就是工作的结束。一般情况下，应先拧紧高强度螺栓，然后再拧紧，每一步都需要严格的扭矩要求。固定电动扭剪扳手要用于大六角高强度螺栓的初始和更终拧紧。因此，各种电动扳手设计用于各种紧固需求。电动电动扭剪扳手的测试方法主要采用简单的测试设备，通过手动加载实现。存在精度低、功能简单、效率低等问题。国外的专用扭矩测试设备可以实现较高的测试效率，但成本昂贵，难以维护和扩展。上述因素严重影响了电动扭剪扳手的生产和检验。在现代测控技术中，智能仪表、总线仪表、虚拟仪表等微机测控仪表充分利用计算机软硬件的优势，不仅增强了参数的测量和处理功能，而且提高了性能。指标。

Shear wrenches are mainly used to tighten shear type high-strength bolts. Its purpose is to destroy the plum blossom head of shear type high-strength bolts. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the bolt box head will break, and then pull out the wrench to pull the trigger and eject the box head, which is the end of the work. In general, high-strength bolts should be tightened first and then tightened, with strict torque requirements required for each step. The fixed electric torque wrench should be used for the initial and final tightening of large hexagonal high-strength bolts. Therefore, various electric wrenches are designed for various tightening needs. The testing method for electric electric torsion shear wrenches mainly uses simple testing equipment and is achieved through manual loading. There are issues such as low accuracy, simple functionality, and low efficiency. Foreign specialized torque testing equipment can achieve high testing efficiency, but it is expensive and difficult to maintain and expand. The above factors have seriously affected the production and inspection of electric torsion shear wrenches. In modern measurement and control technology, microcomputer measurement and control instruments such as intelligent instruments, bus instruments, and virtual instruments fully utilize the advantages of computer software and hardware, not only enhancing the measurement and processing functions of parameters, but also improving performance.

由于尚未建立工业应用中螺栓紧固的相关标准，且人力资源相对便宜，许多风力涡轮机安装单元仍然保留相对落后的螺栓紧固方法。传统的螺栓紧固方法，即锤击力增加的扳手，操作简单，但无法获得准确可靠的螺栓残余载荷，严重威胁风力发电机的运行。

Due to the lack of established standards for bolt tightening in industrial applications in China and the relatively cheap human resources, many wind turbine installation units still retain relatively outdated bolt tightening methods. The traditional bolt tightening method, which is a wrench with increased hammering force, is simple to operate, but cannot obtain accurate and reliable bolt residual load, seriously threatening the safe operation of wind turbines.

用普通冲击扳手或扭矩倍增器或液压扳手初次锁定后，根据螺栓强度等级等条件，比较螺栓螺母尺寸和扭矩值表，然后使用高精度电动扭剪扳手进行精确锁定操作，可大大提高风机的性。电动电动扭剪扳手作为一种精密设备，可用于风力发电机在恶劣自然条件下的长期运行。为了确保风力涡轮机的长期有效运行，有必要注意风力涡轮机上的每个细节，并仔细维护每个部件。

After the initial locking with an ordinary impact wrench, torque multiplier, or hydraulic wrench, compare the bolt and nut dimensions and torque value table based on conditions such as bolt strength grade, and then use a high-precision electric torsion shear wrench for precise locking operation, which can greatly improve the safety of the fan. As a precision equipment, electric electric torque wrench can be used for long-term operation of wind turbines under harsh natural conditions. In order to ensure the long-term effective operation of wind turbines, it is necessary to pay attention to every detail on the wind turbine and carefully maintain each component.
