On face, and correct the cylinder inner circle of pedestal；
B, setting 8 clamping points near the lower flange circumferential edges of pedestal, 8 clamping points are uniformly distributed and near workpiece；
C, pedestal symmetry is pressed, and progressively compress, thus pedestal is clamped；
D, the upper surface of beginning car cylinder；
E, pedestal is adjusted face, machined end face is placed on platen face, the cylinder cylindrical of correction pedestal, make cylinder
Axis is concentric with platen gyroaxis；
F, continuation, by Workpiece clamping, if 8～10 clamping points, are uniformly distributed, symmetrical pressure, progressively clamp, milling flange base
The surface of seat (1), the most rough turn lower flange cylindrical, plane, and the endoporus of boring lower flange, and car remove the 50% of total allowance；
G, half finish turning lower flange cylindrical, plane, endoporus, car removes the 40% of total allowance respectively；
H, the cylindrical of finish turning lower flange, plane, endoporus；
I, by whole for the pedestal workbench being positioned over numerical control machine tool, the endoporus of correction lower flange, center benchmark；
J, again by pedestal clamp；
Nine the first through holes on K, the most successively heavy boring, half right boring last right boring lower flange；
L, last heavy boring, half right boring, nine the second through holes of right boring pedestal upper flange；
M, flange pedestal is holed.
Further improvement of the present invention is: in described step M during boring, uses drilling die to carry out boring location.
Further improvement of the present invention is: it is characterized in that: during boring, uses magnetic drill press boring.
The present invention compared with prior art has the advantage that process for machining is simple, needs to use in the course of processing
The large-sized numerical control milling lathe i.e. numerical control lathe milling machine of diameter more than 5 meters, the pedestal after processing can meet the installation of 9 hydraulic motors to be wanted
Ask, and the installation requirement of self-unloading arm swivel bearing can be met simultaneously.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention；
Label in figure: 1-flange pedestal, 2-cylinder, 3-lower flange, 4-the first through hole, 5-upper flange, 6-the second through hole.
Detailed description of the invention:
