[0001] The utility model relates to the technical field of processing equipment for hoisting holes, in particular to processing equipment for hoisting holes of a large propeller hub. Background Art

[0002] The propeller hub is a component that connects the propeller blades and the aircraft engine shaft. When it rotates, it drives the propeller blades to rotate, thereby generating propulsion. However, when the hub is installed and the aircraft engine and its related components are maintained, it is necessary to connect through the lifting holes. However, on the one hand, traditional lifting hole processing equipment cannot firmly fix the hub to prevent it from falling off during the drilling process and affecting subsequent work. On the other hand, the drilling position of the lifting hole cannot be adjusted at will. Therefore, technical personnel in this field provide a large propeller hub lifting hole processing equipment to solve the problems raised in the above background technology. Utility Model Content
