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)结构简单的高精度扭剪扳手

(1) High precision torsion shear wrench with simple structure

一些气动式和液压式扭剪扳手都附带着气泵和液压泵来提供动力,此类设备附件较多,不便于移动工作。扭剪扳手可在保证精度的前提下进一步简化结构,使用轻巧方便,降低生产成本。

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)动力供应通用化

(2) Generalization of power supply

对于数显式扭剪扳手都有传感器和控制电路，通常采用充电电池供电。在电池电量不足时会直接影响精度。扭剪扳手的充电方式应该向着利用太阳能或机械能的充电的方式发展,太阳能的供电方式.会使扳手在光线充足的地方时刻在充电,机械能的充电方式可以利用拧紧螺栓过程中产生的机械能进行充电。这两种方式可使扭剪扳手始终保持满电状态,不会出现因电量不足导致精度降低的情况,并且可以节约能源。

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)性能稳定的人性化产品

(3) Humanized products with stable performance

作为一种五金工具,设应增强产品的实用性及稳定性。实用的用户手册可以给用户更加人性化的使用指南。除扳手的操作指南外,还应该提供针对于不同规格螺栓时应该施加扭矩的大小等参数。另外,扭剪扳手的设计应该充分遵循人机工程.学的设计原则,手柄长度可以随着所施加的扭矩值的大小的设定来调整。通过调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)参数设定智能化

(4) Intelligent parameter setting

对于规格不同的螺栓,所施加的拧紧力矩大小.也不--样。在更换套筒时扭剪扳手的电控系统应该对套筒的规格进行识别,根据套简规格与螺栓规格的关联关系自动设定所需施加的拧紧力矩大值，实现拧紧力矩峰值自动设定,避免对经验的依赖。

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.

扭剪扳手的螺栓夹持部分参照普通活口扳手的夹持部分,通过调整扳手夹持部分的开口尺寸来适应螺栓头的大小。扭剪扳手的电控系统通过识别扭剪扳手夹持部分的开尺寸来感应被拧紧的螺栓的尺寸进而自动设定相应的拧紧力矩的峰值。这种活口扭剪扳手操作简单，智能化程度高,发展前景广阔。

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.
