Air batch is also called screw driver or pneumatic torque wrench, pneumatic torque wrench, etc., is used to tighten or loosen screws, nuts and other parts of the pneumatic tools.

Development history:

If the earliest version should be the so-called wrench, and then evolved into a torque wrench, that is, the so-called screwdriver, after the rapid development of the electrical era and the industrial era, manual tools gradually faded out of people's eyes, and then the rise of the electric screwdriver paved the way for the industrialization and efficiency of repetitive work. However, while the safety of emerging industries has been paid more and more attention, the wind batch of pneumatic tools has also moved to the front of history.

How it works:

Speaking of the working principle of the air batch is also very simple, nothing more than compressed air through the air compressor, the use of air pressure to drive the blades in the motor in the air batch, and then the blades drive the rotor, and then the rotor drives the screwdriver, and the screwdriver drives the screws to rotate so that the screws and nuts are loosened or tightened. But there is a very noteworthy place in this, how to control the rotation of the screwdriver? People with a little common sense know that if the screw is too tight, the screw or nut will cause slip teeth, but if it is not tight, it will cause the quality of the item or project is not up to standard.

In fact, it is easy to solve the problems mentioned above. The air batch or screw driver that we use and the torque wrench are all fixed sizes or fixed screw sizes and fixed torque. Set a fixed torque value or a certain range on the fixed type of air batch. When the bolt reaches the specified torque value, the torque pressure spring and other devices inside the air batch make it out of touch with the transmission device, so as to achieve the ability of fixed torque.
