Machining equipment special for large standard knot of building crane

The invention belongs to the technical field of building crane standard knot machining, and provides special machining equipment for a building crane large standard knot, which comprises a base, a first rotary assembly, a second rotary assembly, an end face milling power assembly and a side face boring power assembly, the second rotation assembly is slidably connected with the top face of the base, the two end face milling power assemblies are oppositely arranged, and the four side face boring power assemblies are evenly arranged on the two sides of the base. The four sets of side face boring power assemblies bore tenon holes in the ends of chord members at the same time, overall machining of large standard knots is achieved through matched rotation of the first rotation assembly and the second rotation assembly, the machining efficiency is high, the machining precision is high, and machining can be completed through one-time clamping. 本发明属于建筑起重机标准节加工技术领域，提供了建筑起重机大型标准节专用加工设备，包括底座、第一回转组件、第二回转组件、端面铣削动力组件以及侧面镗孔动
