Description
Technical field
The invention belongs to equipment Repairing Technology field, the method for operating for be related to a kind of manual scraping, accurately measuring, can be used for
Numerical control device, conventional equipment, common apparatus, the dovetail guide of special equipment propose high-precision scraping, and realization can be at short notice
Complete heavy partial overhaul precision effect.
Background technology
Accurate two pin measurement scraping method be to improve numerical control device dovetail guide precision for the purpose of, carried out using the detection of two pins
Measurement scraping, using accurate two pins length bar energy direct measurement the geometric accuracy and error of dovetail guide are gone out.
The accurate two pins measurement scraping method time sequential routine can be briefly described as follows：
Step 1, knife mark are formed and force analysis
Flat scraper handle of a knife is withstood hipbone by pincers worker when scraping cast iron surface plate is operated, and both hands hold cutter, make plane scraper
Knife is scraped surface and forms certain cutting angle and apply pressure to cutter head with cast iron surface plate, makes flat scraper blade be critical flat
Face.
At this moment when people hipbone and waist to handle of a knife with thrust, make blade incision cast iron surface plate metal surface and make blade exist
Deeply forward in cut the stain of grinding, then by both hands pressure transition boost power immediately, cutter head is quickly lifted off cast iron
Planar surface.The knife mark form-cutting process of digging type is completed, and scrapes off one layer of very thin metal.The running of knife mark has 3 kinds of sides
Method, i.e., straight pushing manipulation, directly push away plus torsional technique, left and right torsional technique.Straight pushing manipulation produces pane, corner block.Surface is presented microwave shape, table
Face is second-rate, suitably slightly scrapes；Directly push away plus torsional technique produces anti-" 6 " block, just " 6 " block shape, surface is in trickle waveform, surface quality
It is smooth suitably carefully to scrape.Left and right torsional technique produces positive squama block, anti-squama block, swallow wing, swallow body block etc., and surface is in thin song ripple shape, table
Face quality light is smooth, and suitable essence is scraped or scratched.From in terms of scraping process, scraping is the process of force action, and skilled operation degree is determined
The quality of scraping quality is determined.
Step 2, stain rule
By developer (red lead powder) and cast iron surface plate after grinding, the cast iron surface plate surface of bossing shows lap tool
What is shown is full stain, and stain divides bright spot, dense stain, light stain.These stains are a variable in scraping.Through continuous friendship
Constantly scraping is constantly operated for circulation, stain becomes dense, is changed into being uniformly distributed from uneven distribution by rare.Stain is drilled
Change process, is also process that surface smoothness, surface contact precision, surface geometry precision are stepped up.
The stain that grinding shows to be distinguished and treated.Should be with by thick, thin, essence for the knife mark size of dense stain scraping
Equidirectional arrangement is answered in 3 stage prescribed level scrapings, its knife mark direction, and progressively scraping has been scraped totally to stain.Ground display
Afterwards, also stain has been scraped totally with alternate directions scraping for second time.It must be noted that often taking turns scraping, knife mark must staggeredly otherwise will
Affect surface smoothness.There should be dividing for weight on exerting oneself by bright, dense, light to stain in scraping, bright spot, big dense stain are used
Power is big, firmly moderate to most dense stain, to light stain, then retains and does not scrape, and scrapes again during blackening after lower whorl shows,
It must be emphasized that for the bright spot for being distributed in cast iron surface plate horizontal edge, corner.Because hidden cloth is rare, easily neglected by human eye
Slightly, easily leakage is scraped.Because a little often jack-up grinding flat plate, the normal display of obstruction stain in grinding is scraped in leakage, stain can be formed
The phenomenon for scraping fewer and fewer.
Step 3, the stage of scraping 4
In scraping overall process, will typically experience and slightly scrape, thin scraping and precise scraping, scratch 4 stages.Slightly scrape the stage：Slightly scrape
Top priority should first solve the problems, such as Form and position error.The two ends depth of parallelism of such as numerically controlled lathe dovetail guide, if first do not resolved, stays
Solve the depth of parallelism, not only time-consuming but also schedule delays again to after slightly scraping.Coarse scraper mark is roomy, drastically to enter
OK.Each point is only scraped and once do not scrape second.Knife mark direction be it is equidirectional be sequentially arranged, per round transformation once.Through repeatedly
Continuous scraping is circulated, stain becomes dense by rare, by uneven distribution to being uniformly distributed, when arbitrarily the side of scraping (25mm × 25mm) reaches
During to 8～10, accuse when surface roughness reaches Ra2.5～Ra3.2 and slightly scrape stage termination.Carefully scrape the stage：Carefully scrape and slightly scraping
On the basis of carry out.Carefully scraping for task mainly solves surface quality problems, i.e. contact precision, geometric accuracy, and (flatness reaches
0.01mm/500mm2), surface roughness (Ra1.6～Ra3.2), while also to take into account Form and position error.The knife mark carefully scraped is a width of
6～8mm, long 10～12mm, knife mark is proposed with directly pushing away plus torsional technique, just anti-" 6 " the block knife mark of " 6 " block preferably, when any side of scraping
The stage is carefully scraped when reaching at 12～16 and accuses termination.Essence scrapes the stage：Essence is scraped to be carried out on the basis of carefully scraping, and the task that essence is scraped is
Carry out improving scraped surface quality, take into account, appraise and decide Form and position error.Essence is scraped and wants milled flat scraper, sharp, and roll setting will be wanted surely
Gently, it is important to avoid nose angle scratch surface, the wide 5～7mm of smart scraper mark, in addition it is narrower shorter, change depending on scraping plane sizes.
Knife mark is proposed with left handed twist method or right torsional technique, little with Etech during scraping.When stain increases at often arbitrarily just 20～25,
I.e. essence scrapes end, and its cast iron surface plate flatness should be below 0.01mm/500mm2, and surface roughness is 0.8～Ra of Ra 1.6.
Scratch：The effect one for scratching is attractive in appearance, and two is have the function of accumulating lubricating oil.General common decorative pattern has：Oblique decorative pattern, Yan Xinghua
Line and triangle pattern etc..In addition, can also be by the complete of the former decorative pattern of observation and situation about disappearing come the mill after Judge plane work
Damage degree.
