Main points of 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 type (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 and tool accessories.
1. Power output part: It is one of the main components of pneumatic tools, mainly composed of air motor and power output gear. It relies on high-pressure compressed air to blow the motor blades to make the motor rotor rotate, output rotational movement externally, 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 intake holes, they can be divided into single air inlet motors, double air inlet motors, and multiple air inlet motors. No matter what form 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 rotary motion output by the motor. In the automobile manufacturing industry, due to the many ways of threaded connection, most of them are rotary motion, 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 rods and hammer block sets. 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 constant 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 the 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 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 pipes to related gas and electricity, and is pulsating;

6. ​​Air filtration and air pressure adjustment part: As 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 enters the air motor directly without any treatment, the life of the motor will be greatly shortened, resulting in insufficient power output of the entire tool, and unstable, easily causing 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 undertakes 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, which should be maintained and cleaned and replaced regularly after a period of use;

7. Tool accessories: The tool accessories here refer to the tools installed on the body of the pneumatic tool that directly contact the workpiece. The pneumatic triplex undertakes this task. Pneumatic triple parts are mainly composed of barometers, filters, lubricators, pressure regulators, etc. The filter element is built-in in the filter. After a period of use, it must be maintained and cleaned and replaced regularly; such compressed air does not undergo any treatment , Enter the air motor directly, it will greatly shorten the life of the motor, resulting in insufficient power output of the whole tool, and unstable, easy to cause damage to the motor and other parts. For this reason, the compressed air transported by the pipeline to the air tool In between, compressed air filtering and adjusting devices must be installed, including various pneumatic sleeves, extension rods, adapters, cutter heads, etc.;
