The special processing process of the composite ball comprises the following steps of: carrying out vacuum annealing by utilizing a standard steel ball; turning a right end surface, and drilling; turning a left end surface, and drilling; twice finely turning an inner diameter, and turning a clamping groove; carrying out non-oxidation quenching; carrying out secondary polishing treatment on the surface of an outer ball. Through adopting the processing process disclosed by the invention, a product meets the requirements on a technical standard; an outer diameter meets the requirements for accuracy of the original G20 level of the steel ball; the inner diameter and the end surfaces are processed through a process method of replacing grinding with turning; and surface quality reaches a high-accuracy standard; and in addition, the processing method has the more important advantage that the cost is less than 5 yuan and the interchangeability of dimensions completely meets the requirements, therefore a key technical problem is solved.
Description
Technical field
The present invention relates to mechanical manufacturing field, relate to the processing method of a kind of 4 wheel driven electrical automobile constant speed center fork part critical component specifically, core process technology technology.
Background technology
4 wheel driven electrical automobile constant speed center fork is a kind of novel auto parts and components at present, and a critical component-composite balls is arranged in this novel auto parts and components.The structure of this composite balls is that external diameter is a spherical structure, and spherical form tolerance, roundness tolerance are all the same with steel ball, and the steel ball grade of requirement is G20.Internal diameter and end face but are not spherical, and two end faces are planes, and internal diameter is a cylinder, promptly is the interior raceway structure of needle roller.This part processing precision requires very high.Everybody claims the technology development of this key technology for ectosphere inner prop revolution spheroid.Be characterized in that outer surface is a sphere, be used for the low-angle universal turning, inner surface is fluted cylindrical, is used to install needle roller revolution in groups flexibly, and its dimensional accuracy and surface roughness require very high.
The core technology infrastructure product of ectosphere inner prop revolution spheroid by normal processing technology is: get the raw materials ready → the car spherical outside surface → corase grind spherical outside surface → car right side, boring → car left side, boring → rough turn internal diameter → finish turning internal diameter → heat treatment → corase grind spherical outside surface → correct grinding spherical outside surface → correct grinding endoporus.Stock utilization is about 20%, and needing cost is 80 yuan, and dimensional interchangeability is bad.Adopt common process, the product appearance shape and size tolerance that processes does not all reach standard-required, and efficient is low, because resetting, form and position tolerance does not satisfy product needed yet.If can reach standard-required, but, waste man-hour with the so little part of numerical control machining center processing with present Numeric Control Technology.The waste resource, importantly efficient is low, loses more than gain, can't batch machining.
Summary of the invention
In view of the defective that prior art exists, purpose of the present invention is providing a kind of composite balls special processing technology.Can significantly reduce cost, raise the efficiency.
For achieving the above object, the process and the known technology of the present invention's innovation are different fully: be to utilize standard steel ball → vacuum annealing → car right side, boring → car left side, boring → twice finish turning internal diameter, car draw-in groove → non-oxidation quenching → ectosphere surface second polishing to handle.Described technological process is the first step, vacuum tempering; In second step, for mill, car planar end surface height is 25.28 with car, car internal diameter φ 15 height 19.15; In the 3rd step, for mill, car planar end surface panel height is 22.2 car internal diameter φ 13 with car; The 4th step, with car for mill, the empty cutter φ 17 of car, width is that 1.3 boundary's platform thickness are 1.75; In the 5th step, for mill, finish turning internal diameter φ 15.67 guarantees that roughness guarantees cylindricity 0.02 with car; In the 6th step, mill internal diameter φ 15.87 reaches the drawing requirement; The 7th step, vacuum hardening; The 8th step, polishing.
After adopting such scheme, compared with prior art have following beneficial effect: product reaches the technical standard requirement, and external diameter is the required precision of the original G20 level of steel ball, internal diameter, end face adopt with car for mill process, surface quality reaches the high accuracy standard.The more important thing is processing method cost of the present invention less than 5 yuan, the interchangeability of size is satisfied the demand fully, has solved crucial technological difficulties.Raise the efficiency 30 times, cut down finished cost 60 times.Embody the low-carbon (LC) effect fully, and the cost of processing constant speed center fork is lowered at once, solved the core technology difficult point.

The specific embodiment
For understanding the special processing technology of composite balls in depth, be described as follows in conjunction with Fig. 1 to Fig. 6: Fig. 1 is the finished product steel ball, and material is GCr15, HRC58-61.The technological process of Fig. 2 to Fig. 6 is handled for utilizing standard steel ball → vacuum annealing → car right side, boring → car left side, boring → twice finish turning internal diameter, car draw-in groove → non-oxidation quenching → ectosphere surface second polishing.The first step, vacuum tempering; In second step, for mill, car planar end surface height is 25.28 car internal diameter φ, 15 height 19.15 with car; In the 3rd step, for mill, car planar end surface panel height is 22.2 with car, car internal diameter φ 13; The 4th step, with car for mill, the empty cutter φ 17 of car, width is that 1.3 boundary's platform thickness are 1.75; In the 5th step, for mill, finish turning internal diameter φ 15.67 guarantees that roughness guarantees cylindricity 0.02 with car; In the 6th step, mill internal diameter φ 15.87 reaches the drawing requirement; The 7th step, vacuum hardening; The 8th step, polishing.
The present invention is a precision of utilizing standard steel ball G20 level product, guarantees the circularity standard of composite balls external diameter, in order to guarantee every dimensional accuracy of external diameter circularity, carries out vacuum annealing, falls back on the hardness that can machine, and guarantees processability.Employing is with the advanced technologies of car for mill, and by technological requirement car right side, boring, car left side, boring are for guaranteeing the raceway precision of internal diameter, twice finish turning internal diameter, car draw-in groove.All after the processing knot speed, carry out non-oxidation and quench.For guaranteeing outer surface quality, ectosphere surface second polishing is handled.Internal diameter finish grindes.The solid foundation that research and development centre pitches has been established in the invention of this technology.
