Ukulinganiswa kokuthamba kubhekisa kwimeko apho, phantsi kobubanzi obuthile besithuba sovavanyo, iprobe efana nepleyiti ehamba phezulu nasezantsi icinezela isampuli kubunzulu obuthile besithuba. Isimbuku sevektha sokumelana kwesampuli namandla okugoba kunye namandla okungqubana phakathi kwesampuli kunye nesithuba siyalinganiswa. Eli xabiso limele ukuthamba kwephepha.
Le ndlela isebenza kwiintlobo ngeentlobo zephepha langasese elingagugiyo kunye neemveliso zalo, kunye nezinye iimveliso zephepha ezineemfuno zokuthamba. Ayisebenzi kwiinapkin, izicubu zobuso ezisongiweyo okanye ezifakwe i-embossed, okanye iphepha elinobunzima obuphezulu.
1. Inkcazo
Ukuthamba kubhekisa kwinani levektha lokuxhathisa ukugoba kwesampuli ngokwayo kunye namandla okungqubana phakathi kwesampuli kunye nomsantsa xa iprobe yokulinganisa efana nepleyiti icinezelwe kumsantsa wobubanzi nobude obuthile ukuya kubunzulu obuthile phantsi kweemeko ezichazwe ngumgangatho (iyunithi yamandla yi-mN). Okukhona eli xabiso lincinci, kokukhona isampuli ithambile.
2. Izixhobo
Esi sixhobo samkelaIsivavanyeli sokuthamba se-YYP-1000,okwaziwa ngokuba sisixhobo sokulinganisa ukuthamba kwephepha le-microcomputer.
Esi sixhobo kufuneka sifakelwe kwitafile ethe tyaba nezinzileyo, kwaye akufuneki sithintelwe kukungcangcazela okubangelwa ziimeko zangaphandle. Iiparameter ezisisiseko zesixhobo kufuneka zihlangabezane neemfuno ezilandelayo.
3. Iiparameters zezixhobo kunye nokuhlolwa
3.1 Ububanzi beSlit
(1) Uluhlu lobubanzi be-slit yovavanyo lwezixhobo kufuneka lwahlulwe lube ngamabakala amane: 5.0 mm, 6.35 mm, 10.0 mm, kunye ne-20.0 mm. Impazamo yobubanzi akufuneki idlule ±0.05 mm.
(2) Impazamo yobubanzi be-slit kunye nobubanzi, kunye nokujonga ukufana phakathi kwamacala amabini, kulinganiswa kusetyenziswa i-vernier caliper (ene-graduation ye-0.02 mm). Ixabiso eliqhelekileyo lobubanzi kwiziphelo ezimbini kunye nombindi we-slit bububanzi be-slit bokwenyani. Umahluko phakathi kwayo kunye nobubanzi be-slit eqhelekileyo kufuneka ube ngaphantsi kwe-±0.05 mm. Umahluko phakathi kwexabiso eliphezulu kunye nelincinci phakathi kwemilinganiselo emithathu yixabiso le-parallelism error.
3.2 Imilo yeprobe emile okwepleyiti
Ubude: 225 mm; Ubukhulu: 2 mm; Irediyasi ye-arc yomphetho wokusika: 1 mm.
3.3 Isantya esiphakathi sokuhamba kweprobe kunye nomgama wonke wokuhamba
(1) Uluhlu lwesantya sokuhamba esiqhelekileyo kunye nomgama opheleleyo wokuhamba kweprobe, isantya sokuhamba esiqhelekileyo: (1.2 ± 0.24) mm/s; umgama opheleleyo wokuhamba: (12 ± 0.5) nm.
(2) Ukuhlolwa komgama opheleleyo wokuhamba kunye nesantya esiphakathi sokuhamba kwentloko yokulinganisa
① Okokuqala, beka iprobe kwindawo ephezulu yoluhlu lokuhamba, ulinganise ubude h1 ukusuka kumphezulu ophezulu ukuya phezulu kwetafile usebenzisa igeyiji yokuphakama, uze wehlise iprobe uye kwindawo ephantsi yoluhlu lokuhamba, ulinganise ubude h2 phakathi komphezulu ophezulu kunye netafile, uze ulinganise umgama wokuhamba uwonke (kwi-mm) ngu: H=h1-h2
② Sebenzisa i-stopwotch ukulinganisa ixesha elithathwa yi-probe ukusuka kwindawo ephezulu ukuya kwindawo ephantsi, ngokuchanekileyo kwemizuzwana eyi-0.01. Eli xesha malibonakaliswe njengo-t. Emva koko isantya sokuhamba esiqhelekileyo (mm/s) ngu: V=H/t
3.4 Ubunzulu bokufakwa kwiSlot
① Ubunzulu bokufakelwa kufuneka bube yi-8mm.
② Ukuhlolwa kobunzulu bokufakwa kwindawo yokufaka. Usebenzisa i-vernier caliper, linganisa ukuphakama u-B weprobe emile okwepleyiti ngokwayo. Ubunzulu bokufakwa bu: K=H-(h1-B)
4. Ukuqokelelwa, Ukulungiswa kunye nokuCwangciswa kweeSampulu
① Thatha iisampulu ngokwendlela eqhelekileyo, uzicubungule iisampulu, uze uzivavanye phantsi kweemeko eziqhelekileyo.
② Sika iisampulu zibe ziingceba zesikwere eziyi-100 mm × 100 mm ngokwenani leeleya ezichazwe kumgangatho wemveliso, uze uphawule iindlela ezinde nezinqamlezileyo. Ubungakanani obuphambukayo kwicala ngalinye bufanele bube yi-±0.5 mm.
③ Qhagamshela umbane ngokwemiyalelo ye-PY-H613 softness tester, fudumeza ixesha elichaziweyo, uze ulungise i-zero point yesixhobo, uze ulungise ububanzi be-slit ngokweemfuno zekhathalogu yemveliso.
④ Beka iisampulu kwiqonga lomatshini wokuvavanya ukuthamba, uze uzenze zibe linganayo kangangoko kunokwenzeka kwisithuba. Kwiisampulu ezineeleya ezininzi, zibeke ngendlela ephezulu nesezantsi. Misela iswitshi yokulandelela incochoyi yesixhobo kwindawo yencochoyi, cofa iqhosha lokuqala, kwaye iprobe efana nepleyiti yesixhobo iqala ukuhamba. Emva kokuba ihambise umgama wonke, funda ixabiso lokulinganisa ukusuka kwisibonisi, uze ulinganise isampuli elandelayo. Linganisa amanqaku edatha ali-10 kwicala elide nelinqamlezileyo ngokulandelelana, kodwa ungaphindi ulinganiselo lwesampulu efanayo.
