Yintoni ukugrumba?
Indlela yokwemba umngxuma?
Indlela yokwenza ukugrumba ichaneke ngakumbi?
Ichazwe ngokucacileyo apha ngezantsi, makhe sijonge.
1. Iingcamango ezisisiseko zokomba
Ngokubanzi, ukugrumba kubhekisa kwindlela yokucubungula esebenzisa i-drill ukucubungula imingxuma kumphezulu wemveliso. Ngokubanzi, xa kusetyenzwa iimveliso kumatshini wokomba, isuntswana lokomba kufuneka ligqibe iintshukumo ezimbini ngaxeshanye:
① Intshukumo ephambili, oko kukuthi, intshukumo ejikelezayo ye-drill bit ejikeleze i-axis (intshukumo yokusika);
②Intshukumo yesibini, oko kukuthi, intshukumo yomgama we-drill bit ecaleni kwendlela ye-axis ukuya kwindawo yokusebenza (intshukumo yokutya).
Xa ubhobhoza, ngenxa yeentsilelo kwisakhiwo se-drill bit, amanqaku aya kushiywa kwiindawo ezicutshungulwayo zemveliso, ezichaphazela umgangatho wokucubungula we-workpiece. Ukuchaneka kokucubungula ngokubanzi kungaphantsi kwinqanaba le-IT10, kwaye uburhabaxa bomphezulu bumalunga ne-Ra12.5μm, eyecandelo lomatshini orhabaxa. .
2. Inkqubo yokusebenza yokomba
1. Ukumakisha: Ngaphambi kokomba, qala uqonde iimfuno zomzobo. Ngokweemfuno ezisisiseko ezisisiseko zokubhoboza, sebenzisa izixhobo zokumakisha umgca ophakathi wendawo yomngxuma. Umgca ophakathi kufuneka ucace kwaye uchaneke, kwaye uncinci ungcono. Emva kokudweba umgca, ukulinganisa nge-vernier calipers okanye irula yentsimbi.
2. Zoba isikwere sokuhlola okanye isangqa sokuhlola: Emva kokuzoba umgca kunye nokudlula uhlolo, isikwere sokuhlola okanye isangqa sokuhlola esinomgca osembindini womngxuma njengombindi we-symmetry kufuneka sizotywe njengomgca wokuhlola ngexesha lokwemba ukuze kube lula ukuhlola. ngexesha lokomba. kunye noqhelaniso oluchanekileyo lokomba.
3. Ukuqinisekisa kunye nokubetha: Emva kokuzoba isikwere sokuhlola esihambelanayo okanye isangqa sokuhlola, ubungqina kunye nokubethelwa kufuneka kwenziwe ngononophelo. Okokuqala yenza inqaku elincinci, kwaye ulinganise amaxesha amaninzi kumacala ahlukeneyo omgca womgca wokunqumla ukuze ubone ukuba umngxuma we-punch uhlatywe ngokwenene ekudibaneni komgca onqamlezileyo, uze ubethe isampuli ngendlela ethe tye, engqukuva, nebanzi. ukubekwa ngokuchanekileyo. Imela iphakathi.
4. Ukubamba: Sebenzisa iragi ukucoca itheyibhile yomatshini, umphezulu we-fixture, kunye ne-workpiece datum surface, uze ubambe i-workpiece. I-clamping kufuneka ihambe kwaye ithembeke njengoko ifunwa, kwaye ikulungele ukubuza kunye nokulinganisa nangaliphi na ixesha. Kuyimfuneko ukuba uhlawule ingqalelo kwindlela yokudibanisa ye-workpiece ukukhusela i-workpiece ukuba ikhubazeke ngenxa ye-clamping.
5. Uvavanyo lokomba: Uvavanyo lokomba kufuneka lwenziwe phambi kokomba olusesikweni: lungelelanisa i-chisel edge ye-drill bit kunye nombindi womngxuma kwaye ubhora umngxuma ongekho nzulu, kwaye emva koko ukhangele ngokubonakalayo ukuba icala lomngxuma ongekho nzulu lilungile na. Kwakhona kuyimfuneko ukulungisa rhoqo ukutenxa ukwenza umngxuma ongekho nzulu kunye nesangqa sokuhlola i-Coaxial. Ukuba ukutenxa kuncinci, i-workpiece inokutyhalelwa kwicala elichaseneyo lokutenxa ngelixa u-drilling ukuphumeza ukulungiswa ngokuthe ngcembe.
6. Ukugrumba: Ukugrumba koomatshini ngokuqhelekileyo kusekelwe ekusebenzeni kokutya okwenziwa ngesandla. Xa ukuchaneka kovavanyo lokumba ukuchaneka kuyadingeka, ukugaya kunokuqhutywa. Xa ukondla ngesandla, amandla okutya akufanele abangele ukuba i-drill bit igobe ukukhusela i-axis yomngxuma ukuba iguqulwe.
3. Iindlela zokuchaneka okuphezulu kokomba
1. Ukulola i-drill bit sisiqalo sayo yonke into
I-drill bit ehambelanayo kufuneka ikhethelwe ukulolwa ngaphambi kokomba. Ukongeza ekuqinisekiseni i-angle ye-vertex echanekileyo, i-angle yokucoca, kunye ne-bevel edge ye-chisel, i-drill bitana enobude obufanayo bemiphetho emibini yokusika kwaye iyalingene kumgca osembindini we-drill bit, kwaye iindawo ezimbini eziphambili zeflank zigudile. , ukwenzela ukuba kube lula ukubeka iziko kunye nokunciphisa uburhabaxa bodonga lomngxuma. , i-chisel edge kunye neyona nto iphambili yokusika kufuneka ifakwe ngokufanelekileyo (kungcono ukugaya ngokukrakra kwi-grinder kuqala, kwaye emva koko ucolile kwi-oilstone).

2. Umzobo womgca ochanekileyo usisiseko
Xa usebenzisa igeyiji yobude ukuphawula imigca ngokuchanekileyo, okokuqala, kufuneka uqinisekise ukuba ulungelelwaniso luchanekile. Xa uphawula, qiniseka ukuba i-angle phakathi kwe-angle yenaliti kunye neplani yokumakisha ye-workpiece yi-40 ukuya kuma-60 degrees (kunye nolwalathiso lokumakisha), ukwenzela ukuba imigca edibeneyo icace kwaye ilingane. Nika ingqalelo ekukhethweni kwe-scribing plane yedatum. Indiza ye-datum kufuneka iqhutywe ngokuchanekileyo kwaye i-flatness yayo kunye ne-perpendicularity kwiindawo ezikufutshane kufuneka ziqinisekiswe. Emva kokuba umgca wesiphambano sesithuba somngxuma utsaliwe, ukwenzela ukuba kuqinisekiswe ukulungelelaniswa okulula xa ubhobhoza, sebenzisa i-punch ephakathi ukukhupha inqaku eliphakathi kumgca we-cross (i-punch point kufuneka ibe yincinci kwaye isalathiso kufuneka sichaneke).
3. Ukubamba okuchanekileyo ngundoqo
Ngokuqhelekileyo, kwimingxuma enobubanzi obungaphantsi kwe-6 mm, ukuba ukuchaneka akubanga phezulu, ungasebenzisa iipliers zesandla ukuze ubambe i-workpiece yokugaya; kwimingxuma phakathi kwe-6 kunye ne-10 mm, ukuba i-workpiece iqhelekile kwaye ithe tyaba, ungasebenzisa i-pliers ye-flat-nose, kodwa i-workpiece kufuneka ibe I-surface i-perpendicular kwi-spindle yomatshini wokugaya. Xa ubhobhoza umgodi kunye nobubanzi obukhulu, i-flat-nose pliers kufuneka ilungiswe ngeplate yoxinzelelo lwe-bolt; kwizixhobo zokusebenza ezinkulu ezinobubanzi bokomba obungaphezulu kwe-10 mm, sebenzisa indlela yoxinzelelo lwepleyiti yokugoba ukubhola.
4. Ukufumana ngokuchanekileyo isitshixo ngundoqo
Emva kokuba i-workpiece igxininiswe, musa ukukhawuleza ukulahla i-drill. Ulungelelwaniso kufuneka lwenziwe kuqala. Ulungelelwaniso lubandakanya ulungelelwaniso olungatshintshiyo kunye nolungelelwaniso oluguquguqukayo. Into ebizwa ngokuba yi-static alignment ibhekisela kukulungelelaniswa ngaphambi kokuba umatshini wokugaya uqalise, ukwenzela ukuba umgca ophakathi we-spindle yomatshini wokugaya kunye nokudibanisa umgca we-workpiece cross ulungelelaniswa. Le ndlela ikhuselekile kwaye ilungele abaqalayo kwaye kulula ukuyiqonda. Nangona kunjalo, ayithatheli ngqalelo i-swing ye-spindle yomatshini wokugaya, umzekelo. kunye nezinye izinto ezingaqinisekanga, ukuchaneka kokomba kuphantsi. Ulungelelwaniso olunamandla lwenziwa emva kokuba umatshini wokomba uqalisiwe. Ngexesha lokulungelelanisa, ezinye izinto ezingaqinisekanga zithathelwa ingqalelo, kwaye ukuchaneka kuphezulu.
5. Ukuhlolwa ngenyameko kubalulekile
Ukuhlolwa kunokufumanisa ngokuchanekileyo nangexesha elifanelekileyo ukuchaneka komngxuma ukuze kuthathwe amanyathelo ayimfuneko ukuhlawulela. Kwimingxuma enokwemba okuphezulu ngokuchaneka, ngokuqhelekileyo sisebenzisa ukugrumba, ukubuyisela kwakhona, kunye neendlela zokulungisa ngokutsha. Emva kokugrumba umngxuma omncinci kwinqanaba lokuqala, sebenzisa i-caliper ukubona impazamo ye-offset ukusuka kumbindi womngxuma ongezantsi ukuya kwidatum. Emva kokulinganisa kwangempela, bala indawo yomngxuma ongezantsi kunye neziko elifanelekileyo. Ukuba impazamo ayikho ngaphezu kwe-0.10mm, unokwandisa umngxuma. Yandisa ngokufanelekileyo i-engile yencam ye-drill, yenza buthathaka isiphumo sokuzinzisa esizenzekelayo, tyhala ngokufanelekileyo i-workpiece kwicala elifanelekileyo, kwaye ngokuthe ngcembe wandise i-drill incam yedayamitha ukuhlawula. Ukuba impazamo inkulu kuno-0.10mm, ifayile engqukuva elungelelanisiweyo ingasetyenziselwa ukucheba iindonga ezisecaleni zomngxuma ongezantsi. Inxalenye eqingqiweyo kufuneka idibaniswe ne-arc yomngxuma ongezantsi kwinguqu egudileyo.
