In a broad sense, pneumatic tools are mainly tools that use compressed air to drive pneumatic motors and output kinetic energy to work externally. According to their basic working methods, they can be divided into: 1) rotary type (eccentric movable blade type) and 2) reciprocating type (volumetric piston type). Generally, pneumatic tools mainly consist of power output part, operation form conversion part, intake and exhaust path part, operation start and stop control part, tool housing and other main parts. Of course, pneumatic tool operation must also have energy supply part, air filtration and pressure regulation part, and tool accessories.

1. Power output part: It is one of the main components of pneumatic tools, mainly composed of a pneumatic motor and a power output gear. It relies on high-pressure compressed air to blow the motor blades and rotate the motor rotor, outputting rotational motion to the outside and driving the entire operation form conversion part through gears. According to whether the stator and rotor are concentric, pneumatic motors can be divided into concentric motors and eccentric motors. According to the number of intake ports, they can be divided into single intake port motors, double intake port motors, and multi intake port motors. No matter what form of pneumatic motor it is, it relies on compressed air to blow the motor blades and drive the rotor to rotate. When the motor blades rotate at high speed, they constantly rub against the inner wall of the stator. It is the most common vulnerable component in Mazda, so it has high requirements for the quality of compressed air and whether the compressed air contains lubricating oil molecules;

2. The homework format conversion part: It mainly converts the rotational motion output by the motor accordingly. In the automotive manufacturing industry, there are many ways of connecting by threads, most of which are rotational movements, but there are also linear reciprocating movements. For different types of pneumatic tools, the conversion of operation forms mainly includes mechanical clutches and planetary gear sets, friction plate clutches and planetary gear sets, hydraulic cylinders, torsion bars and hammering block sets, etc. The above components are all important parts based on rotational motion, which determines the torque size, speed, tightening accuracy and other important parameters of the pneumatic tightening tool. Due to its constant clutch, compression or torque transformation, its constituent components are easily damaged;

3. The intake and exhaust passage: It is obvious that the intake and exhaust passage is the relevant channel for compressed air to enter and exit, and is the energy supply system to ensure the normal movement of the motor;

4. The motion start and stop control part, commonly known as the pneumatic switch, is prone to damage due to its constant direct contact with the operator and external objects, as well as the presence of many engineering plastic products;

5. Energy supply: Compressed air is mainly formed by compressing the atmosphere with an air compressor, and is transported to relevant gas and electricity sources through compressed air pipelines in a pulsating manner;

6. Air filtration and pressure regulation part: Due to the fact that compressed air is usually transported through seamless steel pipes, corrosion on the inner walls, moisture, dust, and other substances in the compressed air will continue to form over long-term use. If such compressed air is not treated and directly enters the pneumatic motor, it will greatly shorten the service life of the motor, resulting in insufficient and unstable power output of the entire tool, which can easily cause damage to the motor and other components. Therefore, a compressed air filtering and regulating device must be installed between the compressed air transported by the pipeline and the pneumatic tool, and the pneumatic triple joint is responsible for this task. The pneumatic triple component mainly consists of a pressure gauge, a filter, an oil mist device, a pressure regulator, and other parts. The filter has a built-in filter element, which needs to be maintained, cleaned, and regularly replaced after a period of use;

7. Tool attachments: The tool attachments here refer to tools installed on the pneumatic tool body that directly contact the workpiece, and the pneumatic triple piece undertakes this task. The pneumatic triple component mainly consists of a pressure gauge, a filter, an oil mist device, a pressure regulator, and other parts. The filter has a built-in filter element, which needs to be maintained, cleaned, and regularly replaced after a period of use; If such compressed air is not treated and directly enters the pneumatic motor, it will greatly shorten the service life of the motor, resulting in insufficient and unstable power output of the entire tool, which can easily cause damage to the motor and other components. Therefore, compressed air filtering and regulating devices must be installed between the compressed air transported by pipelines and the pneumatic tool, including various types of pneumatic sleeves, connecting rods, conversion joints, cutting heads, etc;
