Description

technical field [0001] The invention relates to an intelligent double-spindle end face milling machine for machining blade root flanges, belonging to the technical field of mechanical equipment. Background technique [0002] A wind turbine is a power generation device that converts wind energy into mechanical energy and then into electrical energy through the blades. The blades are the key components of the wind turbine and need to withstand wind blowing in different directions. Therefore, the alternating stress they bear is very large. The strength and fatigue life requirements of the connecting parts are very high. The blade and the hub pitch bearing of the generator are connected by flanges, and multiple high-strength bolts are locked. In order to ensure the reliable connection between the blade and the hub pitch bearing, it is necessary to make the two connecting flange surfaces of the blade and the hub pitch bearing contact very At the same time, the torque of each fas...

AI Technical Summary

Problems solved by technology

[0005] 1. The larger the pitch circle of the blade root, the longer the circumference. Under the same processing line speed, the overall processing time of the blade root flange will be greatly prolonged, so it is imminent to improve the processing efficiency;

[0006] 2. Due to the large diameter of the blade root, it is difficult to operate the equipment during hoisting and positioning, and there are safety risks. The existing positioning method requires manual locking of the pressure plate and the process of taking the pressure plate and positioning the leaning plate. The operation is cumbersome, time-consuming, and laborious. It is necessary to improve to reduce the difficulty of operation;

[0007] 3. After the equipment is tightened inside the blade root, it needs to be fine-tuned as a whole to ensure that it is parallel to the initial surface of the blade root, reduce the machining allowance, and ensure the perpendicularity between the end surface of the blade root and the axis. The existing manual fine-tuning The method is time-consuming and laborious and has safety risks. It is necessary to improve the fine-tuning method to reduce the difficulty of fine-tuning operations;

[0008] 4. A large amount of dust and high-temperature iron chips will be produced during the milling process. In the past, the equipment was not equipped with a dust removal system, which polluted the production environment. It is necessary to improve the equipment, add a high-temperature resistant dust removal system, and reduce the impact on the equipment during processing. environmental impact
