The utility model relates to the technical field of
machine tools, in particular to a six-axis large-rotation-angle drilling and milling
machine tool which comprises a base, a supporting frame and a first driving seat are fixedly connected to the base, a second driving seat is arranged on the portion, facing the first driving seat, of the supporting frame, a clamp is arranged on the second driving seat, and a
machining platform is arranged on the first driving seat. A
rotating disc is arranged between the supporting frame and the second driving seat, an arc-shaped rack is fixedly connected to the edge of the
rotating disc, and a transmission gear is installed on the side, facing the
rotating disc, of the second driving seat; a first sliding seat is arranged on the second driving seat in a sliding fit mode, and the clamp is installed on the first sliding seat. The second driving base can achieve switching between the horizontal type and the vertical type of the drilling and milling
machine tool through matching of the arc-shaped rack on the rotating disc and the transmission gear, the functions of the horizontal type drilling and milling
machine tool and the functions of the vertical type drilling and milling
machine tool are integrated, and the second driving base and the
machining platform can slide up and down, slide left and right and rotate. Therefore, the six-axis driving effect is achieved.
