定扭矩電動扳手的布景技能是怎樣的?

電動扳手作為一種常見的電動工具,其運用較為頻頻,其間一種能夠完成定扭矩輸出的電動扳手又稱為定扭矩電動扳手?,F有的定扭矩電動扳手包含殼體,殼體上設置有電機即動力源,殼體前端設置有經過傳動組織與電機傳動相連的套桿,套桿作為扭矩輸出結構用于向外輸出扭矩。

As a common electric tool, electric wrench is frequently used. Among them, a kind of electric wrench which can complete the output of constant torque is also called constant torque electric wrench. The existing constant torque electric wrench comprises a shell, the shell is provided with a motor, that is, a power source, and the front end of the shell is provided with a sleeve rod which is connected with the motor through a transmission organization, and the sleeve rod is used as a torque output structure to output torque outwards.
為了能夠完成定扭矩的輸出,電動扳手具有扭矩檢測部分,扭矩檢測部分檢測扭矩輸出結構的輸出扭矩,然后完成到達指定扭矩時中止動力輸出,現有定扭矩電動扳手的扭矩檢測部分根本都是經過檢測電動扳手的電流來完成的。
In order to complete the output of constant torque, the electric wrench has a torque detection part. The torque detection part detects the output torque of the torque output structure, and then stops the power output when reaching the specified torque. The torque detection part of the existing constant torque electric wrench is basically completed by detecting the current of the electric wrench.
當電動扳手施加扭矩必定程度后,套桿的滾動會受阻,這會影響電動扳手的電流輸出,然后判斷扭矩輸出結構處的輸出扭矩,電流畢竟與輸出扭矩只是有對應聯系,而沒有換算聯系,這種經過檢測電流來判斷輸出扭矩的形式存在的問題就是丈量精度差,無法完成在高精度領域中運用。
When the torque of the electric wrench is applied to a certain extent, the rolling of the sleeve rod will be blocked, which will affect the current output of the electric wrench, and then judge the output torque of the torque output structure. After all, the current is only related to the output torque, but not converted. The problem of judging the output torque by detecting the current is poor measurement accuracy, It can not be used in high precision field.
此外現有技能中的,為了豐富電動扳手的功用,電動扳手往往還具有大扭矩和小扭矩輸出才能,但是其為了完成大扭矩、小扭矩輸出之間的轉化,其也是經過雜亂的傳動變速組織來完成的,不只結構雜亂,而且因為整個傳動路徑上減速傳動過多,大扭矩輸出時的套桿轉速極地,電動扳手的作業(yè)效率較差。
In addition, among the existing skills, in order to enrich the function of the electric wrench, the electric wrench often has the ability of large torque and small torque output. However, in order to complete the transformation between the large torque and small torque output, it is also completed through the disordered transmission speed organization, not only the structure is disordered, but also because there are too many decelerations in the whole transmission path, When the torque output is high, the working efficiency of the electric wrench is poor.
