A Processing Technology of Large Flange End Face

Abstract

The invention provides a large-sized flange end face processing technology which comprises the following steps: averagely cutting the end face of a whole circular ring according to the diameter of a flange end face into a plurality of processed sections facilitating the processing; initially leveling a mobile type triaxial numerical control milling machine through a horizontal measurement device;after the mobile type triaxial numerical control milling machine is leveled, preliminarily processing the plane of a certain processed section; changing the installation position of the mobile type triaxial numerical control milling machine, leveling the mobile type triaxial numerical control milling machine, and preliminarily processing the planes of the rest processed sections; after the end face of the whole circular ring is subjected to the preliminary processing, measuring the precision of the processed planes by using the horizontal measurement device, and measuring the remaining work ofa splicing position of the plane of the former processed section by using a height measurement device; inputting the measured data into the mobile type triaxial numerical control milling machine to generate a secondary processing numerical control interpolation procedure, and completing the processing of the plane of the measured processed section to complete the processing of the end face of thewhole circular ring. Field processing of the large-sized flange end face can be implemented, and the processing technology is high in processing precision and high in labor efficiency.

Description

technical field [0001] The invention relates to the field of flange processing, in particular to a large-scale flange end face processing technology. Background technique [0002] In the past, the processing of the flange (sealed door) surface on large structural parts has always been a difficult problem to solve. 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 first and then In tailor welding with structural parts, the deformation of the 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. The traditional processing technology often uses the structure of the rotary frame to process the end face of the large flange structure. However, due to the long length of the rotary arm and the gap in the central a...

[0002] In the past, the processing of the flange (sealed door) surface on large structural parts has always been a difficult problem to solve. 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 first and then In tailor welding with structural parts, the deformation of the 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

The traditional processing technology often uses the structure of the rotary frame to process the end face of the large flange structure. However, due to the long length of the rotary arm and the gap in the central axis, the gap value will be enlarged by the rotary arm, which seriously affects Processing accuracy, and the traditional processing method has a long processing cycle and low efficiency
