Background
Wind energy is an available energy provided to human beings by air flow to do work, and belongs to renewable energy sources (including water energy, biological energy and the like). The kinetic energy of the air flow is called wind energy. The higher the air flow rate, the greater the kinetic energy. The windmill can be used to convert the kinetic energy of wind into rotational motion to drive the generator to generate electricity by transmitting the rotational power of the rotor (consisting of blades driven by aerodynamic force) to the generator through a transmission shaft. By 2008, wind power has produced about 94.1 million kilowatts of electricity worldwide, and has supplied over 1% of the world's usage. Wind energy, while not the dominant source of energy for most countries, has grown more than four times between 1999 and 2005.
The fan blade is used as an important component of the wind power generation device. When wind blows to the blades, the driving force generated by the blades drives the generator to work, and then electric energy is generated. Because the root that rotates in-process blade bears the power great, in order to guarantee life and the safety of blade, the terminal surface of blade needs certain precision guarantee, but because its root size is great, the manual work is polished and can be produced great error, and inefficiency. The existing polishing device adopts a mode of fixing an internal triangular support, certain eccentricity can be caused, and the stability is relatively poor.
