Torsion wrench is an essential tool in equipment maintenance and assembly industry. Tightening various bolts with a certain torque can ensure the reliable connection and normal work of mechanical equipment. With the development of torsion wrench technology, its application in engineering field will be more and more widely.

(1)結(jié)構(gòu)簡(jiǎn)單的高精度扭剪扳手

(1) High precision torsion shear wrench with simple structure

一些氣動(dòng)式和液壓式扭剪扳手都附帶著氣泵和液壓泵來提供動(dòng)力,此類設(shè)備附件較多,不便于移動(dòng)工作。扭剪扳手可在保證精度的前提下進(jìn)一步簡(jiǎn)化結(jié)構(gòu),使用輕巧方便,降低生產(chǎn)成本。

Some pneumatic and hydraulic twist shear wrenches are equipped with air pump and hydraulic pump to provide power. This kind of equipment has many accessories and is not easy to move. The torsion wrench can further simplify the structure on the premise of ensuring the accuracy, which is light and convenient to use and reduces the production cost.

(2)動(dòng)力供應(yīng)通用化

(2) Generalization of power supply

對(duì)于數(shù)顯式扭剪扳手都有傳感器和控制電路，通常采用充電電池供電。在電池電量不足時(shí)會(huì)直接影響精度。扭剪扳手的充電方式應(yīng)該向著利用太陽能或機(jī)械能的充電的方式發(fā)展,太陽能的供電方式.會(huì)使扳手在光線充足的地方時(shí)刻在充電,機(jī)械能的充電方式可以利用擰緊螺栓過程中產(chǎn)生的機(jī)械能進(jìn)行充電。這兩種方式可使扭剪扳手始終保持滿電狀態(tài),不會(huì)出現(xiàn)因電量不足導(dǎo)致精度降低的情況,并且可以節(jié)約能源。

There are sensors and control circuits for digital display torsional shear spanners, which are usually powered by rechargeable batteries. When the battery is low, it will directly affect the accuracy. The charging mode of torsion wrench should be developed towards the charging mode of using solar energy or mechanical energy. The power supply mode of solar energy will make the wrench charge in the place with sufficient light all the time. The charging mode of mechanical energy can use the mechanical energy generated in the process of tightening the bolt to charge. These two methods can make the wrench always keep full power state, and will not reduce the accuracy due to insufficient power, and can save energy.

(3)性能穩(wěn)定的人性化產(chǎn)品

(3) Humanized products with stable performance

作為一種五金工具,設(shè)應(yīng)增強(qiáng)產(chǎn)品的實(shí)用性及穩(wěn)定性。實(shí)用的用戶手冊(cè)可以給用戶更加人性化的使用指南。除扳手的操作指南外,還應(yīng)該提供針對(duì)于不同規(guī)格螺栓時(shí)應(yīng)該施加扭矩的大小等參數(shù)。另外,扭剪扳手的設(shè)計(jì)應(yīng)該充分遵循人機(jī)工程.學(xué)的設(shè)計(jì)原則,手柄長(zhǎng)度可以隨著所施加的扭矩值的大小的設(shè)定來調(diào)整。通過調(diào)整力臂的大小可使操作更加便捷。

As a kind of hardware tool, the practicability and stability of the product should be enhanced in the design. Practical user manual can give users more user-friendly guide. In addition to the operation guide of the wrench, the parameters such as the torque to be applied for bolts of different specifications should also be provided. In addition, the design of the wrench should fully follow the design principle of ergonomics. The length of the handle can be adjusted with the setting of the applied torque value. By adjusting the size of the arm, the operation is more convenient.

(4)參數(shù)設(shè)定智能化

(4) Intelligent parameter setting

對(duì)于規(guī)格不同的螺栓,所施加的擰緊力矩大小.也不--樣。在更換套筒時(shí)扭剪扳手的電控系統(tǒng)應(yīng)該對(duì)套筒的規(guī)格進(jìn)行識(shí)別,根據(jù)套簡(jiǎn)規(guī)格與螺栓規(guī)格的關(guān)聯(lián)關(guān)系自動(dòng)設(shè)定所需施加的擰緊力矩大值，實(shí)現(xiàn)擰緊力矩峰值自動(dòng)設(shè)定,避免對(duì)經(jīng)驗(yàn)的依賴。

For bolts of different specifications, the tightening torque applied is not the same. When replacing the socket, the electric control system of the wrench should identify the specification of the socket, and automatically set the maximum tightening torque according to the relationship between the sleeve specification and the bolt specification, so as to realize the automatic setting of the peak tightening torque and avoid the dependence on experience.

扭剪扳手的螺栓夾持部分參照普通活口扳手的夾持部分,通過調(diào)整扳手夾持部分的開口尺寸來適應(yīng)螺栓頭的大小。扭剪扳手的電控系統(tǒng)通過識(shí)別扭剪扳手夾持部分的開尺寸來感應(yīng)被擰緊的螺栓的尺寸進(jìn)而自動(dòng)設(shè)定相應(yīng)的擰緊力矩的峰值。這種活口扭剪扳手操作簡(jiǎn)單，智能化程度高,發(fā)展前景廣闊。

The bolt clamping part of the torsion shear wrench refers to the clamping part of the ordinary open end wrench, and the opening size of the clamping part of the wrench is adjusted to adapt to the size of the bolt head. The electronic control system of the wrench senses the size of the tightened bolt by identifying the open size of the clamping part of the wrench, and then automatically sets the corresponding peak value of the tightening torque. This kind of wrench is easy to operate, high intelligent and has a bright future.
