Analysis of general pneumatic wrenches

Taizhou fengleiyi machinery&electronic co.,ltd. is a professional manufacturer of pneumatic tools for design, development, production, sales and service. It is located in the middle of China Gold Coastline. Water, land and air transportation is convenient, network, communication and information is developed. Of the coastal business in Zhejiang coastal city - Taizhou here is an important birthplace of China's stock cooperative economy. The company was founded in 2010, the predecessor of Taizhou Yuyu Pneumatic Tools Co., Ltd. Existing staff of more than 300 people, more than 30 professional senior technical staff.

   At present, the main production of industrial-grade assembly of pneumatic tools, is committed to the production industry, cutting-edge products, including professional-level specifications of the gun wind approved, wind guns, especially oil-type, hydraulic pulse pneumatic tools is the industry's cutting-edge products. The company's products are mainly used for automobile, motorcycle, electric car, bicycle assembly and maintenance of motor engines, generators, agricultural machinery, air compressors, small machinery and other products for the assembly of the world's automotive, pipe, ship and other industrial manufacturing and automotive After-sales service market widely used, and exported to Europe and the United States and the Middle East and other countries.

   To analyze the principle of pneumatic wrench, the first is the internal structure of pneumatic impact wrench and related parts of the modeling and analysis, through the analysis of general fasteners to collect engineering data, on the basis of the use of professional three-dimensional solid modeling software to its The physical modeling design and modeling and simulation, and then the various parts of the model, the main impact of the part of the necessary calculation and improvement, to further improve and improve the design of this subject. This topic is based on the engineering machinery design and theoretical test data based on the former, the use of industrial design related to the design concept, these two aspects of the organic combination to a certain extent, this lesson next week, the design reflects the modern machinery Design and manufacture of advanced nature.

   In the manufacture of machinery, the application of various thread connections is very extensive, thread assembly technology is the common technology of the electromechanical industry.It is important that mechanical and electrical products, such as generators, transformers, cars, tractors, machine tools, High, so the requirements of the universal tightening tool is also getting higher and higher, the main features of the pneumatic impact wrench has the following four points: high pressure, powerful, stable performance, long service life.

   Pneumatic motor components mainly by the eccentric cylinder, rotating rotor, live leaves and sealed end caps and other components, mainly to complete the energy conversion to high torque kinetic energy. The compressed air flow from the air compressor, through the pipeline, from the cylinder on both ends of the air inlet into the cylinder chamber, and then use the cylinder eccentric design, the air flow to the rotating rotor on the live leaves, so live The blade drives the rotating rotor to produce the rotation action, the movable blade is close to the inner wall of the cylinder under the action of the centrifugal force, and the air inlet and the outlet are dynamically isolated, after which the rotor uses the airflow to produce the constant pressure difference on the live leaf, When the vane is rotated in the circumference, it passes through the vent at a fixed angle, and the vent will be concentrated in the airflow in each of the spaced vanes, and the discharged air is simultaneously fed into the enclosed cylinder chamber , After repeated rotation is fully utilized, so with a high speed of the rotor, the high-speed rotor through the mechanical structure from the original gas can be converted into high torque kinetic energy.
