A fixed torque electric wrench, also known as an adjustable torque electric wrench, is a type of electric wrench that can set and adjust the torque. Mainly used in the steel structure installation industry, high-strength bolts are installed for connecting steel structure contacts, usually in the form of bolts.

一般來說，高強度螺栓在擰緊前須擰緊，每個階段都需要嚴格的扭矩要求。本實用新型涉及一種適用于高密度六角頭高強度螺栓端部的固定扭矩電動扳手。

Generally speaking, high-strength bolts must be tightened before tightening, and strict torque requirements are required at each stage. The utility model relates to a fixed torque electric wrench suitable for the ends of high-density hexagonal high-strength bolts.

目前，對固定扭矩電動扳手的研究集中在兼具固定值和過載故障功能的數(shù)字顯式扭矩電動扳手上，通過LCD顯示屏窗口進行人性化設(shè)計受到用戶的歡迎。此外，還有扭矩值監(jiān)控終端、峰值設(shè)置和警報功能、無線傳輸功能、與安裝的無線傳輸終端的通信、數(shù)據(jù)記錄和管理。

At present, research on fixed torque electric wrenches is focused on digital explicit torque electric wrenches that have both fixed value and overload fault functions. Humanized design through LCD display windows has been welcomed by users. In addition, there are torque value monitoring terminals, peak setting and alarm functions, wireless transmission functions, communication with installed wireless transmission terminals, data recording and management.

從傳統(tǒng)的手指扭矩扳手到具有多種社會功能的數(shù)字顯式固定扭矩電動扳手，隨著信息技術(shù)的發(fā)展，可以實現(xiàn)質(zhì)的飛躍。傳統(tǒng)的固定扭矩電動扳手有以下幾個優(yōu)點：1.技術(shù)持續(xù)成熟，性能相對穩(wěn)定。

From traditional finger torque wrenches to digital explicit fixed torque electric wrenches with various social functions, with the development of information technology, a qualitative leap can be achieved. Traditional fixed torque electric wrenches have the following advantages: 1. The technology continues to mature and the performance is relatively stable.

2.人性化的管理操作系統(tǒng)界面;強大的數(shù)據(jù)分析和處理的主要功能等。

2. Humanized management operating system interface; The main functions of powerful data analysis and processing.

定扭矩電動扳手缺點：系統(tǒng)組件多任務(wù)復雜性文檔提出了人工智能扭轉(zhuǎn)扳手系統(tǒng)，包括企業(yè)電子標簽、扭轉(zhuǎn)扳手、信息資源管理會計軟件等。通過開發(fā)智能手機芯片來執(zhí)行必要的功能。使用扳手系統(tǒng)時，須能夠同時啟動計算機，對螺栓信息進行編號，編寫網(wǎng)絡(luò)信息記錄學生管理分析軟件，并在相應的螺栓上貼上電子標簽。

Disadvantages of fixed torque electric wrenches: The system components are multitasking and complex. The document proposes an artificial intelligence torsion wrench system, including enterprise electronic labels, torsion wrenches, information resource management accounting software, etc. By developing smartphone chips to perform necessary functions. When using the wrench system, it is necessary to be able to simultaneously start the computer, number the bolt information, write a network information security record student management analysis software, and attach electronic labels to the corresponding bolts.

定扭矩電動扳手的功能只有在教育準備培訓任務(wù)完成后，我們才能充分發(fā)揮，效率低下，操作過程復雜。類似的扭力扳手結(jié)構(gòu)比較復雜。準確度和困難是目前市場上的正扭矩電動扳手在準確度和上都是難題。高精度扳手一般是數(shù)字定扭矩電動扳手，進口產(chǎn)品一般水平較高。低的是扭轉(zhuǎn)銷扳手結(jié)構(gòu)比較簡單，準確度低，很難滿足人們使用其他要求。這也是為什么定扭矩電動扳手不能在相關(guān)知識領(lǐng)域廣泛應用的原因之一。

The function of a fixed torque electric wrench can only be fully utilized after the completion of educational preparation and training tasks, resulting in low efficiency and complex operation process. Similar torque wrenches have a more complex structure. The difficulty in accuracy and price is currently a challenge for positive torque electric wrenches in the market. High precision wrenches are generally digital fixed torque electric wrenches, and imported products generally have a higher price level. The lower price is that the torsion pin wrench has a relatively simple structure and low accuracy, making it difficult to meet other requirements for people to use. This is also one of the reasons why fixed torque electric wrenches cannot be widely used in related knowledge fields.

傳統(tǒng)的定扭矩電動扳手具有應用扭矩值和監(jiān)控扭矩值的功能，但為了應用于其他規(guī)格的螺栓，須手動設(shè)置扭矩值的數(shù)量。不同螺栓的預緊力矩值可參考相關(guān)手冊或公式計算。

Traditional fixed torque electric wrenches have the function of applying torque values and monitoring torque values, but in order to be applied to other specifications of bolts, the number of torque values must be manually set. The pre tightening torque values of different bolts can be calculated by referring to relevant manuals or formulas.
