In the manufacturing process of wind turbines, the processing accuracy and quality of parts are crucial, and CNC processing technology, as an efficient and precise processing method, is widely used in the production of wind power parts. CNC processing technology, namely computer numerical control processing technology, is a method of processing parts by controlling machine tools through computer programs. In the processing of wind power parts, CNC processing technology can achieve high-precision cutting, drilling, milling and other processing operations, thereby ensuring the accuracy and quality of parts. At the same time, CNC processing technology can also realize automated production, improve production efficiency and reduce costs.

[0003] The wind turbine gearbox requires an oil pump for oil lubrication. When the oil pump is running, an oil slinger is usually hung on the pump shaft, and the bottom of the oil slinger is immersed in the lubricating oil in the oil chamber. The pump shaft rotates to drive the oil slinger to rotate and bring up the lubricating oil to lubricate the pump shaft and bearings and other components through the shaft. When the oil slinger for the wind turbine gearbox is CNC machined, an axial positioning structure is required to position and fix it. The existing axial positioning structure of the oil slinger is generally not conducive to convenient clamping support positioning and rapid axial positioning and fixing for CNC machining, and is not convenient for rapid center positioning and fixing of the oil slinger, which greatly affects the convenience of positioning and fixing the oil slinger during machining.
