Abstract
The invention relates to the field of machining, in particular to a method for machining a lens cone part with the mass center deviating from the rotation center. The method includes the following steps that a blank is cast; heat treatment is conducted, wherein quench aging is adopted; a bench worker scribes a blank allowance distribution line with the non-machining surface as a reference; all the surfaces of an installation seat are milled on a milling machine, and the 0.1 mm finish machining allowance is reserved in the ruler lower end face; holes are roughly turned on a lathe, and the 0.5 mm allowance is reserved for the single side of the finish machining surface; heat treatment is conducted, wherein distressing artificial aging is conducted through heat treatment, and machining stress is removed; the finish reference installation surface is machined, in other words, the planeness of the lower end face scraped by the bench worker is within 0.006 mm, the other surface is scraped, and the perpendicularity of the other surface and the lower end face is within 0.006 mm. The operation is simple, vibration generated in the machining process is low, dimensional tolerances of the part can be guaranteed, and part machining accuracy and production efficiency are improved.
Description
Technical field
The present invention relates to field of machining, be specifically related to barycenter and depart from centre of gyration lens barrel class method of processing parts.
Background technology
In photoelectricity series products, often can run into mirror tube kind part, owing to there being strict installation site requirement, the structure barycenter of such part is not often on the centre of gyration.If processed on engine lathe, not only working (machining) efficiency is low, and the circularity in hole, cylindricity are very poor, and two stomidium axialities are more difficult to ensure; Due to the particularity of structure, such part wall thickness is thinner, and barycenter departs from the centre of gyration, can produce circularity and cylindricity poor situation during turning inner hole, and the position dimension at center, hole is also difficult to ensure.This part shape is different from conventional axial workpiece, installation way difficulty.Part length is longer, and the size of a stomidium is relatively less than normal, and clamped one time to process and ensure that the axiality of two stomidiums is at 0.01mm, then cutter and cutter bar is very thin very long, and poor rigidity adds vibration in man-hour comparatively large, is difficult to ensure element precision requirement.Part material is cast aluminium ZLl04, adds and sticks cutter man-hour, easily produces to amass to cut knurl, and surface quality is difficult to ensure.
Usually the processing of such part adopts the mode of upper bent plate and threaded mandrel frock to carry out fine finishining, to ensure final required precision, namely after roughing, carry out a destressing Ageing Treatment, then the processing of datum clamp face is carried out, ensure that lower surface flatness is within 0.01 mm, turner take lower surface as bent plate on benchmark, fine finishining datum level, right-hand member hole and screw thread, and ensure pitch-row size, then with hole and datum level location, be threaded upper spindle, finish turning right-hand member face, ensures axiality 0.01 mm.The drawback that these class methods exist is that part length is longer, after upper spindle, Mold processing is larger, barycenter offset bore axle center is more, the centrifugal force produced after part rotates is larger, add the vibration produced man-hour larger, the geometric tolerances such as cylindricity, axiality in hole are difficult to ensure, product percent of pass is low, has a strong impact on the production cycle.
Summary of the invention
In order to solve the problem, the invention provides a kind of simple to operate, tremble little in process, each dimensional tolerance of part all can be guaranteed, and the barycenter improving part processing precision and production efficiency departs from centre of gyration lens barrel class method of processing parts.
Barycenter of the present invention departs from centre of gyration lens barrel class method of processing parts, comprises the following steps:
The first step, cast blank;
Second step, heat treatment, adopts quench aging process;
3rd step, pincers worker for benchmark, draws blank allowance distributing line with non-machined surface;
4th step, on milling machine, each of milling mounting seat, allowance for finish 0.1 mm is stayed in chi lower surface;
5th step, on lathe, rough turn each hole, to the monolateral reserved 0.5mm surplus of polished surface;
6th step, heat treatment, destressing artificial aging is carried out in heat treatment, eliminates machining stress;
7th step, carries out the processing of smart benchmark installed surface, i.e. the lower surface flatness of pincers worker scraping is within 0.006 mm, and scraping another side and this face perpendicularity are within 0.006mm;
8th step, at universal precision jig boring machine, with part lower surface on benchmark, the other end of centering part within 0.008 mm, boring two stomidium, boring circle, ensure lower surface size, two stomidium axiality 0.006mm, and ensure that right flank is to axle center, hole dimensional uniformity;
9th step, on numerical control lathe, adopt special tooling, take lower surface as bent plate on base pressure parallels, centering boring machine standard hole is within 0.006mm, the centering face vertical with lower surface is within 0.008mm, locate and carry out counterweight and reach principal axis balance, finish turning end face, hole and screwed hole, a collection of machine after, turn around, again clamping, centering other end boring machine standard hole is within 0.006mm, the centering face vertical with lower surface is within 0.008 mm, location, counterweight reaches principal axis balance again, car hole and screwed hole ensure pattern accessory size, geometric tolerances requirement,
The present invention is simple to operate, trembles little in process, and each dimensional tolerance of part all can be guaranteed, and improves part processing precision and production efficiency.
