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. The arm rotation driving device also serves as a balance weight matched with the milling cutter driving device. A chassis tooth ring with a larger diameter is more reliable in stress, so that the levelness of the processing arm can be further guaranteed. Due to the pressing adjustment roller, the influence caused by a main shaft clearance and deformation of a material on the processing precision can be effectively reduced.

Description

technical field [0001] The invention relates to the field of flange processing, in particular to a device for processing the end faces of large flange parts. Background technique [0002] In the past, the flange surface processing on large structural parts has always been a difficult problem. Due to the large size of large structural parts, it is impossible to process the flange surface on a conventional milling machine. Instead, the flange surface is processed separately and then the structural part Tailored welding, the deformation of components is not easy to control, and the levelness is also difficult to meet the construction requirements, such as the flange surface processing on the support cylinder of the floating crane. [0003] Publication number is that the Chinese patent document of 201644883U discloses a kind of special-purpose milling machine for processing the flange end face, has adopted the structure processing the end face of large-scale flange structural me...
