Rack machining process.
Technical solution：A kind of processing method suitable for small-size rack used in the present invention, its procedure of processing are：
（1）, blank to be processed cleaned；
（2）, 2-3 adjusting hole is opened up on blank, blank is fixed by adjusting hole, and is accurately looked for adjusting hole
To the cross centre line of blank, to be straightened blank；
（3）, by the fixing tool on gear-hobbing machine the left and right face of blank is fixed, coarse-fine Milling Machining tooth form it is same
When, carry out coarse-fine milling to the front-back of blank, when tooth Profile Machining uses slotting cutter；
（4）, to rack carry out chamfering tooth punching；
（5）, crack processing carried out to the tooth form of rack using cutting edge；
（6）, machine after rack cleaning, drying, packing, storage；
Wherein, step（4）In tooth punching using profile milling cutter carry out milling.
As the further optimization of the present invention, step of the present invention（1）And step（6）The middle cleaning agent used by with
The raw material of lower parts by weight is made：4-6 parts of deionized water, 4-5 parts of nitrilotriacetic acid, 2-5 parts of trbasic zinc phosphate, cellulose ether 3.5-
4.3 parts and 2.5-3.5 parts of glycerine list certain herbaceous plants with big flowers acid fat.In the present invention rack surface can be effectively removed by using above-mentioned cleaning agent
Stain and greasy dirt, especially suitable for remove rack surface stubbornness organic matter spot, rack surface stain treatment is done
Only, it is possible to increase the surface accuracy of rack processing, makes rack surface precision work in-process reach nanoscale and improve guarantee, tooth
The raising of bar surface overall precision, makes rack suitable for precision optical machinery.
As the further optimization of the present invention, pass through hinge between the stationary plane and stationary plane of fixing tool of the present invention
Chain link.
As further optimization of the invention, after crack processing is carried out to rack tooth form, secondary add is carried out to adjusting hole
Work is molded, and the positioning accuracy of adjusting hole is further improved by using secondary operation forming technique in the present invention, while make adjustment
Minute surface is presented in the outer surface in hole, the assembly precision of rack adjusting hole is reached Nano grade.
As the further optimization of the present invention, adjusting hole of the present invention is located in the middle part of blank and/or both ends, easy to tooth
The fast positioning of bar installation.
Beneficial effect：Compared with prior art, the present invention has the following advantages：The present invention is multiple by being opened up on blank
Adjusting hole, can ensure requirement on machining accuracy, and the present invention carries out tooth punching using cutting, and production efficiency is higher, and the present invention is produced into
This is relatively low, is processed especially suitable for small-size rack, with good economic efficiency；By using secondary operation, tooth is effectively improved
The machining accuracy of bar, enables rack suitable for precision optical machinery.
