Description
Technical field
The present invention relates to a kind of spiral case processing technology, more particularly to a kind of gas outlet work is processed for the spiral case of circular flange
Skill.
Background technology
Spiral case in turbocharger, its measuring basis are generally ACD.Wherein A is the end face at middle case end；C is centre
One endoporus at shell end；D is inlet flange face.Refer to shown in Fig. 1 and Fig. 2, the positioning datum of blank is ZFG.Z is middle case
The black skin at tongue is held, it is close with A；Hole centered on F；It is concentric with C holes；G is located at the inlet flange face D mouth of pipe.In general
Processing technology, all it is first to process outlet flange J because these measuring basis of blank are close to initial alignment benchmark；Positioned again by J
Processing gas inlet flange D；Or A faces C holes (if inlet flange in itself can positioning and directing, also can first process AC and come out)；After ACD comes out,
Remaining position is processed with regard to complete for positioning.Above-mentioned processing technology has the disadvantage that：
1) outlet flange J is circular, also needs orientation point just to position completely；
2) eccentric throw be present with A faces, when processing D and AC by it, the relative position fluctuation in D faces and A faces C holes is larger,
The stricter position degree requirement of difficult satisfaction when processing other positions is positioned using ACD；
3) when by the use of J faces as benchmark processing other positions, because of the shape of itself, poor rigidity is clamped；
4) for difficult-to-machine material, J faces inherently bottleneck, it is not easy to improve.
The content of the invention
It is an object of the invention to provide the spiral case processing technology that a kind of gas outlet is circular flange, and it has processing stable
Property it is good, easy to process and high in machining efficiency the characteristics of, using solve in the prior art spiral case of the gas outlet as circular flange processing
During existing above mentioned problem.
To use following technical scheme up to this purpose, the present invention：
A kind of gas outlet is the spiral case processing technology of circular flange, and it comprises the following steps：
1) two bases in D faces first are processed with the basis of plane Z, centre bore F and mouth of pipe dorsal horn two anchor point X1, X2
Quasi- hole E and K；Wherein, Z faces are the black skin at the tongue of middle case end, and D faces are inlet flange face；
2) positioned by D faces benchmark and two datum holes E and K, process A faces benchmark and C benchmark, A faces are
The end face at middle case end, C are an endoporus at middle case end；
3) positioned by D faces benchmark and two datum holes E and K, process four dorsal horn B and two screw H1；
4) positioned by A faces benchmark, C benchmark and D faces benchmark, carry out other each sequence processing.
Especially, specific procedure of processing is in the step 4)：
Step 1：Carry out positioning pin-and-hole H2 and the M12 spiral shell for processing A faces by A faces benchmark, C benchmark and D faces benchmark
Hole H3；
Step 2：Positioning processing bush hole H4 and exhaust apertures H5 is carried out by A faces benchmark, C benchmark and D faces benchmark；
Step 3：Four M6 screws H6 of positioning processing are carried out by A faces benchmark, C benchmark and D faces benchmark；
Step 4：Positioning processing M18 screws H7 is carried out by A faces benchmark, C benchmark and D faces benchmark.
Beneficial effects of the present invention are that the gas outlet is the spiral case processing technology of circular flange compared with prior art
D benchmark first go out, and are first benchmark；AC is processed by D positioning, AC fluctuation is smaller, relatively stable；The positioning of so other each sequences
All on the basis of D/ACD, positioning datum is unified with measuring basis, will stablize from the aspects of process, meet for processing
Easily reach in terms of drawing size and position degree, CPK (process capability index) value is higher；Adjust, add relative to the polarization of blank
Work center will facilitate compared to car sequence in adjustment；In addition, the two contents to be processed of car sequence can processed using D benchmark
Preprocessing on center, reduce the cutting output of car sequence；Processing J faces are positioned by ACD, fixture easily clamps, and rigidity is good；These give birth to lifting
Production efficiency is highly profitable.
