Composition of pneumatic tools

Pneumatic tool is mainly a tool that uses compressed air to drive a pneumatic motor to output kinetic energy to the outside world. According to its basic working mode, it can be divided into:

1. Rotary type (eccentric movable vane type).
2. Reciprocating type (volume piston type)
General pneumatic tools are mainly composed of main parts such as power output part, operation form conversion part, intake and exhaust part, operation start and stop control part, tool housing, etc. Of course, the operation of pneumatic tools must also have energy supply part, air filtration and air pressure adjustment parts and tool accessories, etc.

Power take-off 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 to make the motor rotor rotate, output rotary motion to the outside, and drive the entire operation form transformation through gears. Partial movement. According to whether the stator and the rotor are concentric, the air motor can be divided into a concentric motor and an eccentric motor. According to the number of air inlet holes, it can be divided into a single air inlet motor, a double air inlet motor and a multi air inlet motor. No matter what form of air motor it is, it relies on compressed air to blow the motor blades to drive the rotor to rotate. When the motor blades rotate at high speed, friction occurs with the inner wall of the stator at all times. It is the most common wearing part in the motor, so it The quality of the compressed air and whether the compressed air contains lubricating oil molecules are very demanding.

Job form conversion part:
It mainly converts the rotary motion output by the motor accordingly. For different types of pneumatic tools, the operation form conversion part is mainly divided into mechanical clutch and planetary gear set, friction disc clutch and planetary gear set, hydraulic cylinder, torsion bar and hammering block set, etc. The above components are all important components based on rotational motion, which determine important parameters such as the torque, speed, and tightening accuracy of the pneumatic tightening tool. Because of its constant clutching, pressure or torque transformation, its components vulnerable to damage.

Intake and exhaust part:
Obviously, the intake and exhaust passages are the relevant passages for the compressed air to enter and exit, and are the energy supply system to ensure the normal movement of the motor.

Motion start and stop control section:
That is, the usual pneumatic switch, because it is in direct contact with the operator and external objects at all times, and many engineering plastic products, it is prone to damage.

Energy supply part:
Compressed air is mainly formed after the air compressor compresses the atmosphere, and is transported to the relevant gas and electricity by the compressed air pipeline, and it is in a pulsating shape.

Air filter and air pressure regulation part:
Since compressed air is usually transported through pipes made of seamless steel pipes, during long-term use, rust on the inner wall, moisture and dust in the compressed air will continue to form. If such compressed air directly enters the air motor without any treatment, the life of the motor will be greatly shortened, resulting in insufficient and unstable power output of the entire tool, which is likely to cause serial damage to parts such as the motor. Between the compressed air conveyed by the pipeline and the pneumatic tool, a compressed air filter and adjustment device must be installed, and the pneumatic triplet undertakes this task. The pneumatic triplet is mainly composed of a barometer, a filter, a lubricator, a pressure regulator, etc. The filter has a built-in filter element, which needs to be maintained, cleaned and replaced regularly after a period of use.

Tool accessories:
The tool accessories here refer to the tools installed on the body of the pneumatic tool that are in direct contact with the workpiece. The pneumatic triplet undertakes this task. The pneumatic triplet is mainly composed of a barometer, a filter, a lubricator, a pressure regulator, etc. , The filter element has a built-in filter element, which needs to be maintained, cleaned and replaced regularly after a period of use; such compressed air directly enters the air motor without any treatment, which will greatly shorten the life of the motor, resulting in the power output of the entire tool. Insufficient and unstable, it is easy to cause damage to the motor and other components in series. For this reason, between the compressed air delivered by the pipeline and the pneumatic tool, a compressed air filter and adjustment device must be installed, including various types of pneumatic sleeves, connecting rods , adapters, cutter heads, etc.
