Ibhola Screw, eyolunye udidi lweebheringi zesixhobo somatshini, sisixhobo esifanelekileyo esinemveliso enokuguqula intshukumo ejikelezayo ibeintshukumo yomgca.Isikrufu sebhola siquka isikrufu, i-nati, isixhobo sokubuyisela umva kunye nebhola, kwaye ineempawu zokuchaneka okuphezulu, ukuguqulwa kunye nokusebenza okuphezulu ngexesha elinye.
Kukho iindlela ezintathu eziphambili zokufakela isikrufu sebhola, ezizezi, isiphelo esinye esisisigxina, enye indlela yokufakela yasimahla; esinye isiphelo silungisiwe, esinye isiphelo sendlela yokufaka inkxaso; zombini iziphelo elimisiweyo indlela yokufaka.
1,Isiphelo esinye silungisiwe, esinye isiphelo sendlela yasimahla
Esinye isiphelo silungisiwe, esinye isiphelo sendlela yokufakela yasimahla: isiphelo esisisigxina seukuzalaingamelana ngaxeshanye amandla e-axial kunye ne-radial force, ngelixa ibhola le ndlela yokuxhasa ilungele kakhulu i-stroke encinci iibheringi ezimfutshane okanye izixhobo zomatshini ezivaliweyo ngokupheleleyo, kuba xa usebenzisa esi sakhiwo sendlela yokumisa oomatshini, ukuchaneka kwayo yeyona nto ingathembekanga, ngakumbi ixesha elide. -I-diameter ratio yeebheringi ezinkulu ze-screw (i-ball screw incinci kakhulu), ukuguqulwa kwayo kwe-thermal kubonakala kakhulu. Nangona kunjalo, kwi-screw ye-1.5m ubude, ukuhluka kwe-0.05 ~ 0.1mm phantsi kweemeko ezahlukeneyo zokubanda kunye nobushushu kuqhelekileyo. Nangona kunjalo, ngenxa yesakhiwo sayo esilula kunye nokufakela okulula kunye nokugunyaziswa, izixhobo zomatshini ezichanekileyo eziphezulu zisasebenzisa esi sakhiwo. Nangona kunjalo, kukho inqaku elifuna ingqalelo ekhethekileyo kukuba ukusetyenziswa kwesi sakhiwo kufuneka kufakwe kwi-grating, usebenzisa i-ring efakwe ngokupheleleyo kwiimpendulo, ukuze ukwazi ukudibanisa ngokupheleleyo ukusebenza.
2, isiphelo esinye silungisiwe, esinye isiphelo semowudi yenkxaso
Esinye isiphelo sigxininiswe kwaye esinye isiphelo sixhaswa: ukuthwala kwisiphelo esimisiweyo kunokumelana ne-axial kunye ne-radial forces, ngelixa isiphelo esixhasayo simelana kuphela nemikhosi ye-radial kwaye sinokwenza inani elincinci le-axial float, kunye nokunciphisa okanye ukuphepha. ukugoba kwesikrufu ngenxa yobunzima baso. Ukongeza, i-thermal deformation ye-screw yenkxaso yebhola ye-screw ikhululekile ukuba yolulele kwicala elinye. Ngoko ke, esi sesona sakhiwo sisetyenziswa kakhulu. Ngokomzekelo, iileyile ze-CNC zasekhaya ezincinci kunye naphakathi, amaziko omatshini amileyo, njl njl. zonke zisebenzisa esi sakhiwo.
3,Kulungiswe kuzo zozibini iziphelo
Zombini iziphelo zesikrufu zilungisiwe: Ngale ndlela, ukuthwala kwisiphelo esisisigxina kunokuthwala amandla e-axial ngaxeshanye, kwaye ukulayishwa kwangaphambili okufanelekileyo kungasetyenziswa kwi-screw ukuphucula ukuqina kwenkxaso ye-screw, kunye ne-thermal. ukuguqulwa kwesikrufu nako kunokubuyekezwa ngokuyinxenye. Ke ngoko, izixhobo ezinkulu zoomatshini, izixhobo zomatshini onzima kunye noomatshini bokubhonqa obuchanekileyo kunye noomatshini bokugaya basetyenziswa kakhulu kwesi sakhiwo. Ngokuqinisekileyo, kukho ukusilela, oko kukuthi, ukusetyenziswa kwesi sakhiwo kuya kwenza uhlengahlengiso lusebenze ngakumbi; ukongeza, ukuba ukufakela kunye nokulungelelaniswa kweziphelo ezimbini zokulayishwa kwangaphambili kukhulu kakhulu, kuya kukhokelela kwi-stroke yokugqibela ye-screw kune-stroke yoyilo, i-pitch iya kuba nkulu kune-pitch yoyilo; kwaye ukuba iziphelo ezibini ze-nut preload azanelanga, iya kukhokelela kwisiphumo esichaseneyo, esiya kubangela ngokulula ukungcangcazela komatshini, okukhokelela ekunciphiseni ukuchaneka. Ngoko ke, ukuba isakhiwo sigxininisekile kuzo zombini iziphelo, i-disassembly kufuneka ilungiswe ngokungqongqo ngokuhambelana nemiyalelo, okanye ngoncedo lwesixhobo (i-dual frequency laser interferometer) ukulungelelanisa, ukwenzela ukuba kungabangela ilahleko engeyomfuneko.
