Analyze the use of pneumatic tools to maintain the main points

Broadly speaking, the pneumatic tool is mainly used to drive the air through the compressed air and the external output kinetic energy of a tool, according to its basic work can be divided into: 1) rotary (eccentric movable blade) .2) reciprocating (Pneumatic Piston) The general pneumatic tool is mainly composed of the power output part, the working part transformation part, the intake and exhaust road section, the operation opening and stop control part, the tool shell and so on. Of course, the pneumatic tool operation must also have the energy supply part, Air filter and air pressure adjustment part and tool accessories.

    1, the power output part: it is one of the main components of pneumatic tools, mainly composed of pneumatic motor and power output gear, it relies on high pressure compressed air blowing motor blades leaving the motor rotor rotation, external rotation movement, and through The gears drive the entire form of operation into part of the movement. According to the stator and the rotor is the same, pneumatic horse pneumatic motor can be divided into concentric motor and eccentric motor, according to the number of intake holes, can be divided into single inlet motor, double inlet motor and multi-inlet motor. No matter what form of the air motor, are relying on compressed air to blow the motor blades to drive the rotor rotation, the motor blades in the high-speed rotation, the moment and the inner wall of the friction, it is the most common parts of the motor, The quality of compressed air and compressed air containing lubricants are high requirements?

    2, the transformation of the form of work: it is mainly the motor output of the rotary movement of the corresponding conversion. In the automobile manufacturing industry, because of the many ways to thread connection, most of the rotary motion, of course, there are linear reciprocating motion. For different types of pneumatic tools, the operating part of the conversion part is 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 based on the rotary motion of the important components, which determines the pneumatic tightening tool torque, speed, tightening accuracy and other important parameters, because of its non-stop clutch, compression or torque conversion, so its components Vulnerable

    3, into the exhaust section: Obviously, into the exhaust part of the compressed air is out of the relevant channel, is to protect the motor normal movement of the energy supply system;

    4, the movement of the opening and stopping control part, that is usually the pneumatic switch, because it is always and the operator and the external objects in direct contact, and multi-engineering plastic products, it is prone to damage;

    5, the energy supply part: compressed air is mainly compressed air compressor will be formed after the compressed air pipeline to the relevant gas and electricity, and was pulsating;

    6, air filtration and air pressure adjustment part: the compressed air is usually through the seamless steel pipe manufacturing pipeline, in the long-term use, the inner wall of the corrosive, compressed air in the water, dust, etc. will continue to form. If such a compressed air without any treatment, directly into the air motor, it will lead to greatly shorten the life of the motor, resulting in the entire tool power output is insufficient, and unstable, easy to cause motor and other parts of the chain damage, The compressed air from the pipeline to the pneumatic tools must be provided between the compressed air filter, the adjustment device, the pneumatic triplicate bear the task. Pneumatic tandem is mainly composed of barometer, filter, oil mist, regulator and other components, including filter built-in filter, after a period of time to carry out maintenance cleaning, regular replacement;

    7, tool attachment: Here the tool attachment is installed in the pneumatic tool body directly with the workpiece in direct contact with the tools, pneumatic triple bear the task. Pneumatic tandem is mainly composed of barometer, filter, oil mist, regulator and other parts, including the filter built-in filter, after a period of time to carry out maintenance cleaning, regular replacement; such compressed air without any treatment , Directly into the air motor, it will lead to greatly shorten the life of the motor, resulting in the entire tool power output is insufficient, and unstable, easily lead to motor and other parts of the chain damage phenomenon, for this in the pipeline by the compressed air to pneumatic tools Must be set between the compressed air filter, adjust the device, including all kinds of pneumatic sleeve, then the rod, adapter,
