定扭矩電動(dòng)扳手也叫可調(diào)扭矩電動(dòng)扳手，是電動(dòng)扳手的一種，其主要特點(diǎn)是扭矩可以設(shè)定，而扭矩是可調(diào)的。主要用于鋼結(jié)構(gòu)安裝行業(yè)，專門安裝鋼結(jié)構(gòu)高強(qiáng)度螺栓，高強(qiáng)度螺栓是用來連接鋼結(jié)構(gòu)觸點(diǎn)的，通常采用螺栓的形式。
Fixed torque electric wrench, also known as adjustable torque electric wrench, is a kind of electric wrench. Its main feature is that the torque can be set and the torque is adjustable. It is mainly used in the steel structure installation industry to install high-strength bolts of steel structure. High-strength bolts are used to connect steel structure contacts, usually in the form of bolts.
定扭矩電動(dòng)扳手的優(yōu)缺點(diǎn)
Advantages and disadvantages of fixed torque electric wrench
一般來說，高強(qiáng)度螺栓在擰緊之前須擰緊，每個(gè)階段都要求有嚴(yán)格的扭矩要求。本實(shí)用新型涉及一種定扭矩電動(dòng)扳手，適用于高密度大六角頭高強(qiáng)度螺栓的端部。
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, which is applicable to the end of high density large hexagon head high strength bolts.
目前對定扭矩電動(dòng)扳手的研究多集中在兼具定值和過載故障功能的數(shù)字式顯式定扭矩電動(dòng)扳手，并通過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、無線傳輸功能、與已安裝的無線傳輸終端通信、數(shù)據(jù)記錄和管理。
At present, the research of constant torque electric wrench is mostly focused on the digital explicit constant torque electric wrench with both constant value and overload fault functions, and it is welcomed by users through the humanized design of LCD display window. In addition, there are torque value monitoring terminal, peak setting and alarm function, wireless transmission function, communication with installed wireless transmission terminal, 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 the traditional finger torque wrench to the digital explicit fixed torque electric wrench with various social functions, with the development of information technology, a qualitative leap can be achieved. The existing fixed 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 main 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，通過建立一系列發(fā)展智能手機(jī)芯片來完成一個(gè)必要的功能。使用扳手系統(tǒng)時(shí)，須能夠同時(shí)啟動(dòng)計(jì)算機(jī)并對螺栓信息編號，創(chuàng)建網(wǎng)絡(luò)信息記錄學(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)完成后我們才能充分發(fā)揮，效率低，操作過程復(fù)雜。類似的扭力扳手結(jié)構(gòu)比較復(fù)雜。準(zhǔn)確性和困難目前，市場上的定扭矩電動(dòng)扳手在精度和上都是難題。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，水平一般來說較高。低的是扭力針扳手結(jié)構(gòu)相對簡單，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)知識領(lǐng)域方面沒有能力得到廣泛應(yīng)用的原因之一。
Disadvantages of fixed torque electric wrench: the system carries out the multi-task complexity of components, which is proposed in the literature as an artificial intelligent torque wrench system, including enterprise electronic label, torque wrench, information resource management accounting software, etc., and completes a necessary function by establishing a series of smart phone chips. When using the wrench system, you must be able to start the computer and number the bolt information at the same time, create the network information security record student management analysis software, and paste the electronic label on the corresponding bolt. The function of torque wrench needs to be fully played after the teaching preparation and education tasks are completed. It is inefficient and the operation process is complex. Similar torque wrenches have complex structures. Accuracy and price difficulties At present, the precision and price of the fixed torque electric wrench on the market are difficult. High-precision wrenches are generally digital fixed-torque electric wrenches, which are imported products, and the price level is generally high. The low price is that the torque pin wrench has relatively simple structure and low precision, which is difficult to meet the different requirements of people. This is also one of the reasons why torque wrench is not able to be widely used in relevant knowledge fields.
智力低下?，F(xiàn)有的固定扭矩電動(dòng)扳手具有應(yīng)用扭矩值和監(jiān)測扭矩值的能力，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 value and monitor torque value, but how many torque values need to be manually set to apply to bolts of different specifications. The pre-tightening torque of different bolts can be calculated by referring to relevant manuals or formulas. At present, only some products of special industries have the information of preloaded bolts. The specific value of pre-tightening force of ordinary bolts is determined based on experience, which is one of the reasons preventing the use of fixed torque electric wrench.
