Abstract
The invention discloses a device for processing a large-size flange surface. The device comprises a milling cutter driven by a milling cutter driving device, wherein the milling cutter and the milling cutter driving device are arranged at one end of a processing arm; an arm rotation driving device for driving the processing arm to rotate is arranged at the other end of the processing arm; a main shaft is arranged at a position, which is close to the middle of the processing arm, on the processing arm; the processing arm rotates around the main shaft serving as a center; a pressing adjustment roller for adjusting the levelness of the processing arm is also arranged at a position, which is close to the edge of a flange to be processed, on the processing arm. By adopting a structure that the milling cutter driving device and the arm rotation driving device are respectively arranged at the two ends of the processing arm, the device is favorable for in-site processing of the large-size flange surface.
