目前對(duì)定扭矩電動(dòng)扳手的研究多集中在兼具定值和過(guò)載故障功能的數(shù)字式顯式定扭矩電動(dòng)扳手，并通過(guò)LCD顯示窗口的人性化設(shè)計(jì)受到用戶的歡迎。此外，還有扭矩值監(jiān)控終端、峰值設(shè)定和報(bào)警功能、無(wú)線傳輸功能、與已安裝的無(wú)線傳輸終端通信、數(shù)據(jù)記錄和管理。
At present, the research on constant torque electric wrench mostly focuses on the digital explicit constant torque electric wrench with constant value and overload fault functions, and is welcomed by users through the humanized design of LCD display window. 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)的手指扭矩扳手到各種社會(huì)功能的數(shù)字式顯式固定扭矩電動(dòng)扳手，隨著信息技術(shù)的發(fā)展可以實(shí)現(xiàn)了質(zhì)的飛躍?，F(xiàn)有的定扭矩電動(dòng)扳手具有以下幾個(gè)優(yōu)點(diǎn):①技術(shù)不斷成熟，性能比較穩(wěn)定;（2）人性化管理操作系統(tǒng)界面;強(qiáng)大的數(shù)據(jù)分析處理主要功能等。
From traditional finger torque wrenches to digital explicit fixed torque electric wrenches with various social functions, a qualitative leap can be achieved with the development of information technology. The existing constant torque electric wrench has the following advantages: ① The technology is constantly mature and the performance is relatively stable; (2) Humanized management operating system interface; Powerful data analysis and processing functions.
固定扭矩電動(dòng)扳手缺點(diǎn):系統(tǒng)進(jìn)行組件多任務(wù)復(fù)雜性文獻(xiàn)中提出了作為一種人工智能扭力扳手系統(tǒng)，包括企業(yè)電子標(biāo)簽、扭力扳手、信息資源管理會(huì)計(jì)軟件等，通過(guò)建立一系列發(fā)展智能手機(jī)芯片來(lái)完成一個(gè)必要的功能。
Disadvantages of fixed torque electric wrench: the system carries out component multi task complexity The literature proposed that as an artificial intelligence torque wrench system, including enterprise electronic tags, torque wrenches, information resource management accounting software, etc., a necessary function can be achieved by building a series of smart phone chips.
使用扳手系統(tǒng)時(shí)，須能夠同時(shí)啟動(dòng)計(jì)算機(jī)并對(duì)螺栓信息編號(hào)，創(chuàng)建網(wǎng)絡(luò)信息安全記錄學(xué)生管理分析軟件，并在相應(yīng)的螺栓上粘貼電子標(biāo)簽。力矩扳手的功能需要在教學(xué)準(zhǔn)備教育工作任務(wù)完成后我們才能更好地發(fā)揮，效率低，操作過(guò)程復(fù)雜。類似的扭力扳手結(jié)構(gòu)比較復(fù)雜。
When using the wrench system, it must be able to start the computer at the same time and number the bolt information, create the student management analysis software for network information security records, and paste electronic labels on the corresponding bolts. The function of the torque wrench can only be fully exerted after the teaching preparation and education tasks are completed. It is inefficient and the operation process is complex. Similar torque wrenches have complex structures.
準(zhǔn)確性和價(jià)格困難目前，市場(chǎng)上的定扭矩電動(dòng)扳手在精度和價(jià)格上都是難題。高精度扳手一般是數(shù)字式定扭矩電動(dòng)扳手，進(jìn)口產(chǎn)品，價(jià)格水平一般來(lái)說(shuō)較高。價(jià)格低的是扭力針扳手結(jié)構(gòu)相對(duì)簡(jiǎn)單，精度低，難以滿足人們使用不同要求。這也是扭矩扳手在相關(guān)知識(shí)領(lǐng)域方面沒(méi)有能力得到廣泛應(yīng)用的原因之一。
Difficulty in accuracy and price At present, the fixed torque electric wrench on the market is difficult in accuracy and price. High precision wrenches are generally digital constant torque electric wrenches, imported products, generally speaking, the price level is high. The low price is that the torque pin wrench is relatively simple in structure and low in accuracy, which is difficult to meet people's different requirements. This is one of the reasons why torque wrenches are not able to be widely used in relevant knowledge fields.
智力低下。現(xiàn)有的固定扭矩電動(dòng)扳手具有應(yīng)用扭矩值和監(jiān)測(cè)扭矩值的能力，但需要手動(dòng)設(shè)置多少扭矩值才能適用于不同規(guī)格的螺栓。不同螺栓的預(yù)緊力矩值可參照有關(guān)手冊(cè)或公式計(jì)算。目前，只有一些特殊行業(yè)的產(chǎn)品有預(yù)壓螺栓的信息。普通螺栓預(yù)緊力的具體值是根據(jù)經(jīng)驗(yàn)確定的，這是阻礙使用定扭矩電動(dòng)扳手的原因之一。
Mental retardation. The existing fixed torque electric wrench has the ability to apply torque values and monitor torque values, but it requires manual setting of torque values to be applicable to bolts of different specifications. The pretightening torque of different bolts can be calculated by referring to relevant manuals or formulas. At present, only some products in special industries have information about preloading bolts. The specific pre tightening force of ordinary bolts is determined based on experience, which is one of the reasons that hinder the use of constant torque electric wrench.
