Analyze the main points of the use and maintenance of pneumatic tools

Broadly speaking, a pneumatic tool is mainly a tool that uses compressed air to drive a pneumatic motor to output kinetic energy to the outside. According to its basic working mode, it can be divided into: (1) rotary type (eccentric movable blade type). (2) Reciprocating (volume piston type) general pneumatic tools are mainly composed 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, the operation of pneumatic tools must also have energy supply. Parts, air filtration and air pressure adjustment parts, tool accessories, etc.

1. Power output part: It is one of the main components of the pneumatic tool, 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 rotational movement to the outside, and pass The gear drives the entire operation form to transform part of the movement. According to whether the stator and rotor are concentric, pneumatic horse air motors can be divided into concentric motors and eccentric motors. According to the number of air inlets, they can be divided into single air inlet motors, double air inlet motors and multiple air inlet motors. No matter what kind of air motor, it relies on compressed air to blow the motor blades to drive the rotor to rotate. When the motor blades rotate at high speed, they always rub against the inner wall of the stator. It is the most common vulnerable part in the motor. The quality of compressed air and whether the compressed air contains lubricating oil molecules are very demanding;

2. Operation form conversion part: It mainly converts the rotation motion output by the motor correspondingly. In the automobile manufacturing industry, because there are many ways of threaded connection, most of them are rotary motions, of course, there are also linear reciprocating motions. For different types of pneumatic tools, the operation form conversion part is mainly divided into mechanical clutches and planetary gear sets, friction plate clutches and planetary gear sets, hydraulic cylinders, torsion bars and hammer block sets, etc. The above components are all important components based on rotary motion, which determine the torque, speed, and tightening accuracy of the pneumatic tightening tool. Due to its continuous clutch, pressure or torque change, its component parts Vulnerable to damage;

3. Inlet and exhaust path: Obviously, the inlet and exhaust path are related channels for compressed air to enter and exit, and are an energy supply system that guarantees the normal movement of the motor;

4. The movement start and stop control part, that is, the usual pneumatic switch, because it is in direct contact with the operator and external objects at all times, and there are many engineering plastic products, it is prone to damage;

5. Energy supply part: Compressed air is mainly formed by air compressors compressing the atmosphere, which is transported by compressed air pipelines to related gas and electricity, and is pulsating;

6. Air filtration and air pressure adjustment: As compressed air is usually transported through pipelines 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, it will greatly shorten the life of the motor, resulting in insufficient power output of the entire tool, and unstable, which may easily cause damage to the motor and other parts. Between the compressed air transported by the pipeline and the pneumatic tools, compressed air filtering and regulating devices must be installed, and the pneumatic triplex assumes this task. Pneumatic triple parts are mainly composed of barometers, filters, lubricators, pressure regulators and other parts. Among them, the filter has a built-in filter element. After a period of use, it should be maintained and cleaned and replaced regularly;
