Imikhiqizo

Isivinini esiphezulu sokugaya ucezu olulodwa machining

Ukucutshungulwa kwediski kanye nokucubungula ucezu olulodwa izindlela ezimbili zokucubungula ezisetshenziswa njengamanje ekucubunguleni izingxenye ze-optical.Eqinisweni, ukucubungula ucezu olulodwa kunezinzuzo eziningi.Ingaqeda izinqubo ezisizayo njengepuleti eliphezulu, ipuleti eliphansi nokuhlanza.Ikakhulukazi ekukhiqizeni ngobuningi, ngenxa yokucubungula okuphezulu, amahora owesilisa athathwe yizinqubo eziyinhloko ayancipha, kuyilapho amahora omuntu osizayo abanjwe ukucubungula idiski maningi.Nakuba eminyakeni yamuva nje, inqubo yokusiza iye yaqaphela kancane kancane ukushintshwa kwemishini kanye ne-semi-automation, okulungele ukuthuthukisa ukusebenza kahle kokukhiqizwa kwenqubo eyisizayo, okwamanje, inqubo eyisizayo isenezinkinga ezifana nokusebenza kanzima, ukusebenza kahle okuphansi, indawo enkulu yomhlaba kanye ukungcoliswa kwemvelo okukhulu.Ukuzijwayeza kubonisa ukuthi ukucubungula ucezu olulodwa kunezinzuzo ezinhle, ikakhulukazi kumalensi anama-engeli amakhulu okuvula.
1.Umklamo we-single piece machining fixture
Ukulungiswa okusetshenziselwa ukucubungula ucezu olulodwa kulula kakhulu, njengoba kuboniswe ku-Fig. 5-18.U-D ubungako obuhambisana nendingilizi yangaphandle yesiqeshana sokusebenza, esingasebenzisa ukunemba kwamaleveli amane.Lapho i-eccentricity ye-workpiece ingaqinile kakhulu, ukubekezelelana kwendilinga yangaphandle ye-workpiece kungamukela ukubekezelela ukugaya okulukhuni, njenge-F9.Ubukhulu bodonga lwe-clamp bungaba ngu-2 ~ 3mm.Ubukhulu D bunganqunywa ubukhulu bonqenqema lomsebenzi.Kudingekile ukuvimbela udonga lwangaphandle lwe-fixture ekuxhumaneni nobuso bepuleti lokugaya elihle ngesikhathi somshini.
Uma ucezu lokusebenza luyi-convex eyisicaba noma ingxenye ye-concave eyisicaba, indawo lapho i-clamp ithinta khona ngaphansi kwendawo yokusebenza iyisicaba.Lapho ucindezela ucezu lokusebenza, ipuleti lerabha eliwugqinsi elingu-2mm lingafakwa.Ngalesi sikhathi, i-workpiece ayikho esimweni esiboshwe ku-clamp, futhi akukho ukujikeleza okuhlobene phakathi kwe-workpiece ne-clamp etholakala ngesikhathi sokucutshungulwa, kungakhathaliseki ukuthi i-workpiece iku-spindle noma ukunyakaza kwesigqila, okuqinisekisa ukucubungula okubushelelezi. .Uma indawo engenziwanga ngomshini i-convex noma i-concave, indawo ehlanganisiwe kufanele yenziwe ngomshini ibe yindilinga ehambisanayo, njengoba kukhonjisiwe ku-Fig. 5-19.

2.Umklamo wamathuluzi okugaya we-single piece machining
(1)Ukusatshalaliswa kwezingcezu zokugaya idayimane endaweni yamathuluzi abrayo
Uma i-angle yokuvula ye-workpiece inkulu ngokuqhathaniswa, ifana nesilinganiso se-angle yokuvula yesibuko sepuleti kanye ne-angle yokuvula yepuleti lokugaya ekucubungulweni kokwenza idiski jikelele, futhi ukusatshalaliswa kwepuleti lokugaya idayimane kuyafana. njengalokho ekucutshungulweni kokwenza idiski, okungukuthi, ukuguga kobuso bepuleti lokugaya elicolisekileyo kufanele kuhambisane nokugqoka kwe-cosine ngesikhathi sokusetshenziswa kwepuleti lokugaya elicolekileyo.Uma ukuvuleka kwendawo yomshini womsebenzi womsebenzi kushintsha endaweni ephansi ngesikhathi somshini, kungakhathaliseki ukuthi i-convex noma i-concave, izingcezu zokugaya ezinhle emaphethelweni epuleti lokugaya elihle kufanele zihlelwe kakhulu;Uma kungenjalo, uma imbobo ishintsha ibe phezulu, izingcezu zokugaya ezinhle kakhulu engxenyeni emaphakathi zingahlelwa.
Uma i-angle yokuvula ye-workpiece encane, i-angle yokuvula ipuleti lokugaya elihle livame ukuba likhulu kune-angle yokuvula yesibuko sesibuko.Ngalesi sikhathi, ukusatshalaliswa kwezingcezu ezinhle zokugaya epulatifeni elihle lokugaya kungase kube mncane.Emishinini eqhubekayo, uma indawo yokuvula i-workpiece ishintsha ibe phezulu, i-engeli yokuchezuka ye-eksisi yesiqeshana sokusebenza esihlobene ne-spindle ingalungiswa ibe nkulu;Uma indawo yokuvula ishintsha ibe phansi, i-engeli yokuchezuka ingancishiswa.
(2) Ukuklama nokucubungula isisekelo sediski sokugaya esihle
Ukuze uqinisekise ukuthi ukuphuma kwendawo yepuleti lokugaya elicolekileyo ngesikhathi somshini kuhlangabezana nezimfuneko zokunemba, ukuchezuka kwesikhungo esiyindilinga sendawo yebhola eyisisekelo ukusuka ku-eksisi yokuzungezisa yepuleti lokugaya elicolekileyo kufanele libe ngaphakathi kwebanga elivumelekile.Ngenxa yalesi sizathu, ukwakheka kwesisekelo ngokuvamile kuthatha indawo eyi-cylindrical, ukuma kobuso ekugcineni kanye nokubopha intambo.Njengoba kuboniswe ku-Fig. 5-20, i-surface a yindawo yokuma kwe-radial futhi indawo engu-B iyindawo yokuma kwe-axial.

3.Umklamo we-intermediate joint
Ukuphuma kwe-radial runout kanye nokuphela kobuso bokuphela kweshaft eyinhloko ye-qjm-40 indawo encane eyindilinga yesicwengi esinesivinini esikhulu kanye nesicwengisisi esinesivinini esikhulu esingu-qjm-100 esiphakathi nendawo esiyindilinga singaphansi kuka-001mm. ukugaya i-disc ball ukuhlangabezana nezidingo, kufanele kube nokuhlangana okuhle okuphakathi.Ingxenye exhuma isihlanganisi esimaphakathi kanye ne-shaft eyinhloko ingafaniswa ne-F8 noma i-E8.Uma kukhona noma iyiphi inkinga noma ukungqubuzana phakathi kwe-radial datum kanye ne-axial datum, i-axial datum isewukuphikisana okuyinhloko, okungukuthi, ukuqinisekisa i-perpendicularity yobuso bokuphela, kungcono ukwandisa imvume ye-radial, okuyinto enhle kakhulu. ukulawula ukuhlangana kwelunga nokuphotha.
4.Izidingo ze-Coplanar ze-shaft eyinhloko kanye ne-pendulum shaft yesihlungi
Lapho i-shaft eyinhloko yesicwengisisi ingeyona i-coplanar ngendiza yokushwiba ye-pendulum shaft, ama-axes alinganayo we-pendulum shaft kanye nepuleti elilengayo angeke abe yi-collinear, nakuba i-shaft eyinhloko, i-joint kanye nepuleti eliphansi kuqinisekisa ukuphakama okuphakathi okudingekayo. ngesikhungo se-quasi spherical.Kulokhu, uma i-concave surface icutshungulwa, inkinga ayinkulu, ngoba ubude be-pendulum shaft ephuma ngaphandle kohlaka lwe-pendulum buncane;Kodwa-ke, uma indawo ye-convex icutshungulwa, futhi lapho ithuluzi lokugaya likumnyakazo oyinhloko, iphutha lokuchezuka elibangelwa i-non-coplanar ligqama kakhulu ngenxa yobude obude be-pendulum shaft ephumela ngaphandle kohlaka lwe-pendulum, ikakhulukazi uma I-curvature radius ye-workpiece inkulu, izodala ubunzima ekucubunguleni.Ngalesi sikhathi, uma ipuleti lesibuko se-convex lixhunywe ne-shaft eyinhloko, isimo singcono.
5.Ukudlidliza kohlaka lokushwiba
Ukudlidliza kohlaka lokushwiba kuvame ukuvela ekuphumeni kwe-axial kokuphela kwenduku yepiston yesilinda sengalo yokushwibeka.Ngokuyinhloko kunezimo ezimbili zalokhu kuphuma: eyodwa ibangelwa iphutha le-quasi spherical centre, futhi imvamisa yalokhu kudlidliza ivame ukuhambisana nemvamisa yokushwibeka kohlaka lokushwiba;Ngakolunye uhlangothi, ngenxa yokuthi i-pendulum shaft ayiyona i-collinear ne-symmetry axis ye-hanging plate, imvamisa yalokhu kudlidliza ivame ukuba phezulu kakhulu kunaleyo yohlaka lwe-pendulum, futhi lokhu kudlidliza kunomthelela omkhulu kukhwalithi yomshini eyedlule.
Ngemva kokunaka izinkinga ezingenhla, ukucubungula ucezu olulodwa kungenziwa kahle kakhulu.Isakhiwo se-workshop sizobe sihlangene futhi sihlelekile ngenxa yokuqedwa kwamapuleti aphezulu naphansi, ukuhlanza nezinye izinqubo.Njengoba i-workpiece ingaboshiwe ku-fixture, isisebenzi singayisebenzisa kalula, okuyinzuzo ekuthuthukiseni umkhiqizo kanye nekhwalithi yomkhiqizo.
