Abstract
The invention discloses a piston machining process. The piston machining process is characterized by comprising the following steps that (1) a piston pin hole is drilled; (2) pin boss pits are milled in the two sides; (3) a spigot is turned; (4) an oil return groove is milled; (5) an outer circle, a top face, an annular groove, an annular bank and a chamfer are roughly and accurately turned, the spigot is positioned, a six-spindle automatic lathe is adopted, and a forming turning tool is adopted; (6) intermediate inspection is conducted; (7) the piston pin hole is broadened; (8) a pin boss oil hole is drilled; (9) the piston pin hole is subjected to rough boring and semi-fine boring; (10) a skirt section ellipse is finely turned, specifically, a piston bush is turned, and a high-speed steel turning tool is adopted; (11) deburring is conducted; (12) the piston pin hole is finely bored, specifically, the pin hole is angularly positioned, a fine boring machine is adopted for machining, and the high-speed steel turning tool is adopted; (13) intermediate inspection is conducted; (14) an annular clamping groove is cut; (15) chamfers are cut in the inner side of a pin hole seat; (16) the piston pin hole is subjected to roll extruding; (17) deburring is conducted; (18) a piston is cleaned and blown to be clean; (19) the piston is subjected to final inspection; and (20) the front skirt part is assembled and subjected to size reinspection. The machining process is simple, many repeated procedures are omitted, and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of piston machining process.
Background technology
The processing technique that current piston adopts is more complicated, also without unified specification, it does not have unified standard, the steel part quality causing production is uneven, a lot of operations that repeat also make under production efficiency, increase the work burden of workman, make the competitiveness of product in market not high simultaneously.For some operators just entered a profession, it does not have a clear and definite method technique, cause, when operation, mistakes and omissions often occur, in some instances it may even be possible to cause serious consequence.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of piston machining process, and this processing technique is simple, eliminates a lot of repeatability operation, improves work efficiency.
For achieving the above object, the invention provides 1) bore piston pin hole: with outer round surface and interior top and inner surface for roughing standard, selecting Z148 building-block machine, cutter is high speed steel twist drill；
2) milling both sides key seat pit: with outer round surface inner surface for positioning datum, selects 80618 production millers, profile milling cutter；
3) car seam: with cylindrical, end face location, lathe special for piston, carbide tool；
4) milling oil-recovery tank: seam positions, ZF014 lathe special for piston, high-speed steel milling disk cutter；
5) coarse-fine turning end face annular groove ring bank chamfering, seam positions, six-shaft automatic lathe, shaped profile turning cutter；6) intermediate survey；7) piston pin hole is expanded: self-centering clamping, key seat angularly positions basal plane, Z149 building-block machine, high-speed steel reamer；8) lead plug seat oilhole: select 4023 bench drills, high-speed steel drill；9) heavy boring, half right boring piston pin hole: select diamond fine boring machine processing, carbide tool；10) finish turning skirt section is oval: piston is harnessed an animal to a cart machining, high-speed steel bit；11) deburring；12) right boring piston pin hole: with pin-and-hole for angular location, select diamond fine boring machine processing, high-speed steel bit；13) intermediate survey；14) annular groove is cut；15) chamfering inside pin-and-hole seat is cut；16) edging piston pin hole；17) deburring；18) cleaning blows off piston；19) piston is examined eventually；20) before assembling, skirt portion packet size is rechecked.
The invention has the beneficial effects as follows: processing technique of the present invention is simple, eliminate a lot of repeatability operation, improve work efficiency.
