High-speed numerical control drilling and milling composite machine tool

The invention discloses a high-speed numerical control drilling and milling composite machine tool, and relates to the technical field of drilling and milling composite machine tools, the high-speed numerical control drilling and milling composite machine tool comprises a base, the top end of the base is connected with a placing frame through bolts, and vertical-horizontal switching mechanisms are arranged at the positions, corresponding to the two sides of the placing frame, of the top end of the base. The traction plate is pushed to drive the two vertical frames to slide on the two sides of the containing frame, the lifting plate is forced to slide on the vertical frames, the portal frame is pushed to rotate along the vertical plates, and the angle of the portal frame is changed according to needs. The traction plate and the vertical frame are pushed to slide, the lifting plate is forced to slide and ascend and descend in the vertical frame, and therefore the portal frame is driven to rotate along the verti
