電動扭剪扳手主要用于一次擰緊螺栓。它的使用非常簡單，即將電源開關(guān)拉到螺栓上。電動剪切扳手主要用于緊固剪切型高強度螺栓。用于將電源開關(guān)拉向螺栓，直到剪切型高強度螺栓的箱頭斷裂。扭矩剪切扳手可用于初始擰緊和終擰緊。用于在擰緊螺栓之前調(diào)整扭矩。扭矩剪切扳手也是一種恒定電動扭剪扳手。用于先調(diào)整旋轉(zhuǎn)角度，然后擰緊螺栓。電動角度扳手是專門用于緊固鋼架角度處螺栓的電動扳手，其用途與電動扭矩剪切扳手的原理相同。

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. A torque shear wrench can be used for initial and final tightening. Used to adjust torque before tightening bolts. The torque shear wrench is also a constant electric torque shear wrench. Used to adjust the rotation angle first and then tighten the bolts. An electric angle wrench is a specialized electric wrench used to tighten bolts at the angle of a steel frame, and its purpose is the same as the principle of an electric torque shear wrench.

剪切扳手主要用于緊固剪切型高強度螺栓。其目的是破壞剪切型高強度螺栓的梅花頭。工作時，將扳手頭與螺栓頭對齊，拉動開關(guān)開始工作。幾秒鐘后，螺栓箱頭會斷裂，然后拔出扳手拉動扳機彈出箱頭，這就是工作的結(jié)束。一般情況下，應先擰緊高強度螺栓，然后再擰緊，每一步都需要嚴格的扭矩要求。固定電動扭剪扳手要用于大六角高強度螺栓的初始和終擰緊。因此，各種電動扳手設計用于各種緊固需求。電動電動扭剪扳手的測試方法主要采用簡單的測試設備，通過手動加載實現(xiàn)。存在精度低、功能簡單、效率低等問題。國外的專用扭矩測試設備可以實現(xiàn)較高的測試效率，但成本昂貴，難以維護和擴展。上述因素嚴重影響了電動扭剪扳手的生產(chǎn)和檢驗。在現(xiàn)代測控技術(shù)中，智能儀表、總線儀表、虛擬儀表等微機測控儀表充分利用計算機軟硬件的優(yōu)勢，不僅增強了參數(shù)的測量和處理功能，而且提高了性能。指標。

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 pop out 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 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 fastening needs. The testing method for electric torque wrenches mainly uses simple testing equipment and is achieved through manual loading. There are problems 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 seriously affect 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.

由于尚未建立工業(yè)應用中螺栓緊固的相關(guān)標準，且人力資源相對便宜，許多風力渦輪機安裝單元仍然保留相對落后的螺栓緊固方法。傳統(tǒng)的螺栓緊固方法，即錘擊力增加的扳手，操作簡單，但無法獲得準確可靠的螺栓殘余載荷，嚴重威脅風力發(fā)電機的運行。隨著國內(nèi)風電行業(yè)的發(fā)展和風機采購和維護投資的增加，改革傳統(tǒng)的螺栓緊固方法并提供的工具勢在必行。用普通沖擊扳手或扭矩倍增器或液壓扳手初次鎖定后，根據(jù)螺栓強度等級等條件，比較螺栓螺母尺寸和扭矩值表，然后使用高精度電動扭剪扳手進行精確鎖定操作，可大大提高風機的性。電動電動扭剪扳手作為一種精密設備，可用于風力發(fā)電機在惡劣自然條件下的長期運行。為了確保風力渦輪機的長期有效運行，有必要注意風力渦輪機上的每個細節(jié)，并仔細維護每個部件。

Due to the lack of relevant standards for bolt tightening in industrial applications in China and the relatively inexpensive 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 residual bolt loads, seriously threatening the safe operation of wind turbines. With the development of the domestic wind power industry and the increase in investment in wind turbine procurement and maintenance, it is imperative to reform traditional bolt fastening methods and provide advanced tools. After the initial locking with a regular impact wrench, torque multiplier, or hydraulic wrench, compare the bolt and nut dimensions and torque value table based on bolt strength grade and other conditions, and then use a high-precision electric torque wrench for precise locking operation, which can greatly improve the safety of the fan. Electric torque wrench, as a precision equipment, can be used for long-term operation of wind turbines under harsh natural conditions. 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.
