Seven components of pneumatic tools

The pneumatic tool is mainly a tool that uses compressed air to drive the air motor and output kinetic energy. According to its basic working mode, it can be divided into: 1) rotary type (eccentric movable vane type). 2) reciprocating type (volumetric piston type) The general pneumatic tools are mainly composed of the power output part, the operation part conversion part, the intake and exhaust part, the operation opening and stopping control part, the tool housing and other main parts. Of course, the pneumatic tool must also have the energy supply part, air filtration and air pressure adjustment. Part and tool attachments, etc.

Power output section

It is one of the main components of pneumatic tools. It mainly consists of a pneumatic motor and a power output gear. It relies on high-pressure compressed air to blow the motor blades to rotate the motor rotor, to output the rotary motion, and to transform the entire operation form through gears. Part of the movement. According to whether the stator and the rotor are concentric, the pneumatic horse air motor can be divided into a concentric motor and an eccentric motor. According to the number of intake holes, it can be divided into a single air inlet motor, a double air intake motor and a multi-inlet motor. 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, so it The quality of the compressed air and the presence of lubricating oil molecules in the compressed air are very high.

Job form conversion section

It mainly converts the rotary motion of the motor output accordingly. In the automobile manufacturing industry, since there are many ways of screwing, most of them are rotary motions, and of course there are linear reciprocating motions. For different types of pneumatic tools, the operating part conversion part is mainly divided into mechanical clutch and planetary gear set, friction plate clutch and planetary gear set, hydraulic cylinder, torsion bar and hammer block group. The above components are all important components based on the rotary motion. It determines the important parameters of the torque, speed, and tightening accuracy of the pneumatic tightening tool. Due to its constant clutching, compression or torque conversion, its components are Vulnerable to damage.

Intake and exhaust section

Obviously, the intake and exhaust section is the relevant passage for the ingress and egress of compressed air, and is an energy supply system that ensures the normal movement of the motor.

Motion on and off control section

That is to say, the pneumatic switch generally described is susceptible to damage because it is in direct contact with the operator and external objects at the moment, and is multi-engineered plastic products.

Energy supply section

The compressed air is mainly formed by the air compressor compressing the atmosphere, and is transported by the compressed air pipeline to the related gas, and is pulsating.

Air filtration and air pressure adjustment section

Since compressed air is usually transported through pipes made of seamless steel pipes, rust on the inner walls, moisture in compressed air, dust, etc., will continue to form during long-term use. If such compressed air does not undergo any treatment and directly enters the air motor, the life of the motor will be greatly shortened, resulting in insufficient power output of the whole tool and instability, which may cause damage to the connecting parts of the motor and the like. Compressed air filtration and adjustment devices must be provided between the compressed air delivered by the pipeline and the pneumatic tools. The pneumatic triple joints undertake this task. The pneumatic triplex is mainly composed of a barometer, a filter, an oil mister, a pressure regulator, etc., wherein the filter has a built-in filter element, and is subjected to maintenance cleaning and regular replacement after being used for a period of time.

Tool attachment

The tool attachment here refers to a tool that is directly in contact with the workpiece on the body of the pneumatic tool, and the pneumatic triple joint undertakes the task.

The pneumatic triplex is mainly composed of a barometer, a filter, an oil mister, a pressure regulator, etc., wherein the filter has a built-in filter element, which is to be maintained and periodically replaced after being used for a period of time; such compressed air is not subjected to any treatment. Direct access to the air motor will result in a greatly shortened motor life, resulting in insufficient power output and instability of the entire tool, which may cause damage to the components such as the motor. For this purpose, the compressed air from the pipeline to the pneumatic tool Compressed air filtration and adjustment devices must be provided, including various types of pneumatic sleeves, posts, adapters, cutter heads, etc.
