Abstract
The invention relates to a machining process of a self-disassembling suspension arm base driven by nine hydraulic motors. The machining process includes the steps that the base is overall placed on a working table top of a surfacing lathe, namely a flange base of the base is placed on the working table top, and an inner circle of a barrel of the base is corrected; pressure is symmetrically applied to the base, compression is achieved gradually, and therefore the base is clamped; the upper end face of the barrel is started to be turned; face adjusting is carried out on the base, the machined end face is arranged on the working table top of the surfacing lathe, and an outer circle of the barrel of the base is corrected; then rough turning is carried out on the outer circle and the plane of a lower flange, an inner hole is bored in the lower flange, and 50% of the total working allowance is removed in a turning mode; rough turning and semi finish turning are carried out on the outer circle, the plane and the inner hole of the lower flange, and finish turning is carried out on the outer circle, the plane and the inner hole of the lower flange until the size requirements are met; the overall base is placed on a working table of a numerical control machining machine tool to be clamped, rough turning, semi finish turning and finish turning are carried out on nine first through holes in the lower flange sequentially until the size requirements are met; rough turning, semi finish turning and finish turning are carried out on nine second through holes in an upper flange of the base until the size requirements are met; holes are drilled in the flange base. The machining process has the advantages that manufacturing is simple, and the work efficiency is improved.

B, near the lower flange circumferential edges of pedestal, establish 8 clamping points, 8 clamping points are uniformly distributed and near workpiece;
C, pedestal symmetry to be exerted pressure, and progressively compress, thus pedestal is clamped;
The upper surface of D, beginning car cylindrical shell, until car is to the size of cylindrical shell;
E, pedestal being adjusted face, being placed on platen face by processing end face, correct the cylindrical shell cylindrical of pedestal, make cylinder axis turn round concentric with platen;
F, continue Workpiece clamping, if 8 ~ 10 clamping points, be uniformly distributed, symmetry is exerted pressure, and progressively clamps, the surface of milling flange pedestal (1), then rough turn lower flange cylindrical, plane, and the endoporus of boring lower flange, and car removes 50% of total allowance;
G, rough turn half finish turning lower flange cylindrical, plane, endoporus, car goes 40% of total allowance respectively;
The cylindrical of H, finish turning lower flange, plane, endoporus are until dimensional requirement;
I, be positioned on the workbench of numerical control machine tool by whole for pedestal, correct the endoporus of lower flange, center benchmark;
J, again pedestal to be clamped;
K, nine the first through holes then successively on heavy boring, the last right boring lower flange of half right boring are until size;
Nine the second through holes of L, last heavy boring, half right boring, right boring pedestal upper flange are until size;
M, to hole on flange pedestal.
Further improvement of the present invention is: when holing in described step M, adopts drilling die to carry out boring location.
Further improvement of the present invention is: it is characterized in that: during boring, adopts magnetic drill press boring.
The present invention compared with prior art has the following advantages: process for machining is simple, the numerical control lathe milling machine using large-sized numerical control milling lathe and diameter more than 5 meters is needed in process, pedestal after processing can meet the installation requirement of 9 hydraulic motors, and can meet the installation requirement of self-unloading arm swivel bearing simultaneously.
