Ho mamella le ho hlahloba likhoele (1)

Ho mamella le ho lemoha ha khoele e tlamahanngoa

Sepheo sa khaolo ena ke ho utloisisa litšobotsi tsa ho feto-fetoha ha khoele e tloaelehileng le tšebeliso ea litekanyetso tsa mamello.Tlhokahalo ea ho ithuta ke ho utloisisa tšusumetso ea liphoso tse kholo tsa geometri tsa khoele e tloaelehileng mabapi le ho fapanyetsana;Theha mohopolo oa bophara ba ts'ebetso ea khoele;Ka ho sekaseka kabo ea sebaka sa mamello ea likhoele, tseba litšobotsi tsa mamello e tloaelehileng ea khoele le ho lekana le khetho ea ho nepahala ha khoele;Utloisisa lintlha tse amang ho nepahala ha ho falla ha screw ea mochini.

Mofuta oa khoele le litlhoko tsa tšebeliso

1, khoele e tloaelehileng

Hangata e bitsoa fastening thread, e sebelisoa haholo-holo bakeng sa ho kopanya le ho tiisa likarolo tse fapaneng tsa mechine.Litlhoko tsa tšebeliso ea mofuta ona oa khokahanyo ea khoele ke screwability (bonolo kopano le disassembly) le ho tšepahala ha kgokelo.

2. Khanna khoele

Mofuta ona oa khoele hangata o sebelisoa ho fetisa motsamao kapa matla.Tšebeliso ea likhokahano tse nang le likhoele li hloka ho ts'epahala ha matla a fetisoang kapa ho nepahala ha phallo e fetisitsoeng.

3. Khoele e thata

Mofuta ona oa khoele o sebelisetsoa ho tiisa manonyeletso.Tšebeliso ea litlhoko tsa khoele li thata, ha ho na metsi a lutlang, ha ho na moea o lutlang le ho tsoa ha oli.

5. Tekanyo ea khoele

1. Tekanyo e akaretsang

Ho hlahloba khoele ka khoele gauge ke tekanyo e akaretsang.Tlhahisong ea batch, khoele e akaretsang e sebelisoa mokhoa o akaretsang oa ho lekanya.Tekanyo e akaretsang e etsoa ho sebelisoa sekala sa khoele (tekanyo e akaretsang ea moeli) ho ea ka litekanyetso tsa bophahamo ba khoele e hlahisitsoeng pejana (molao-motheo oa Taylor). sekala sa khoele se arotsoe ka “pass gauge” le “stop gauge”.Ha u etsa liteko, "pass gauge" e ka atleha ho phunya le workpiece, 'me "stop gauge" ha e khone ho phunya kapa sekoti se sa fellang, ebe khoele e tšoaneleha.Ho fapana le hoo, "pass gauge" e ke ke ea fetoloa, e bontšang hore nate e nyenyane haholo, bolt e kholo haholo, 'me khoele e lokela ho lokisoa.Ha "stop gauge" e ka feta ka har'a workpiece, e bolela hore nate e kholo haholo, bolt e nyenyane haholo, 'me khoele ke sehlahisoa sa litšila.

2. Tekanyo e le 'ngoe

Bakeng sa likhoele tse tloaelehileng tsa boholo bo boholo, likhoele tse nepahetseng le likhoele tsa koloi, ntle le ho potoloha le ho ts'epahala ha khokahano, ho na le litlhoko tse ling tse nepahetseng le tse sebetsang, 'me tekanyo e le' ngoe e sebelisoa ka kakaretso tlhahisong.

Ho na le mekhoa e mengata ea ho lekanya khoele e le 'ngoe, e tloaelehileng ka ho fetisisa ke ho sebelisa microscope ea sesebelisoa sa bokahohle ho lekanya bophara, sekontiri le halofo ea Angle ea khoele.Sesebelisoa sa microscope se sebelisetsoa ho holisa profil ea khoele e lekantsoeng le ho lekanya bophahamo ba eona, halofo ea Angle le bophara bo bohareng ho ea ka setšoantšo sa khoele e lekantsoeng, kahoo mokhoa o boetse o bitsoa mokhoa oa setšoantšo.

Tlhahisong ea sebele, mokhoa oa ho lekanya li-pin tse tharo o sebelisoa ho lekanya bophara bo bohareng ba khoele e ka ntle.Mokhoa ona o bonolo, o nepahetseng haholo oa ho lekanya ebile o sebelisoa haholo

Kakaretso e khuts'oane

1. Khoele e tloaelehileng

(1) Mantsoe a sehlooho le litekanyetso tsa geometri tsa likhoele tse tloaelehileng ke: mofuta oa leino la motheo, bophara bo boholo (D, d), bophara bo nyane (D1, d1), bophara bo bohareng (D2, d2), bophara bo bohareng bo sebetsang, bophara bo le bong bo bohareng ( D2a, d2a) bophara ba 'nete bo bohareng, sekontiri se phahameng (P), mofuta oa leino Angle (a) le mofuta oa leino halofo ea Angle (a/2), le bolelele ba screw.

(2) Khopolo ea bophara bo bohareng ba ketso le maemo a tšoanelehang a bophara bo bohareng

Boholo ba bophara ba bohareng bo sebetsang bo ama ho phunya, 'me boholo ba bophara ba sebele ba bohareng bo ama ho tšepahala ha khokahanyo.Hore na bophara bo mahareng boa tšoaneleha kapa che bo lokela ho latela molao-motheo oa Taylor, 'me bophara ba' nete ba mahareng le bophara bo bohareng bo laoloang ka har'a sebaka sa mamello sa bophara bo mahareng.

(3) Boemo ba ho mamella khoele e tloaelehileng Tekanyetsong ea mamello ea khoele, mamello ea d, d2 le D1, D2 e ​​hlalositsoe.Maemo a bona a mamello ka ho fapana a bontšoa ho Lethathamo la 9-1.Ha ho tolerances ba boletsweng bakeng sa sekontiri sekontiri le leino mofuta (laolwa ke sebaka sa ho mamella bophara bophara bohareng), 'me ha ho tolerances boletsoeng bakeng sa bophara nyenyane d ea khoele kantle le bophara e khōlō D ea khoele ka hare.

(4) Phapang ea motheo Bakeng sa likhoele tse ka ntle, kheloho ea motheo ke ho kheloha holimo (es), ho na le e, f, g, h mefuta e mene;Bakeng sa likhoele tse ka hare, ho kheloha ha motheo ke ho kheloha ka tlaase (El), ho na le mefuta e 'meli ea G le H. Kereiti ea mamello le ho kheloha ha motheo ho etsa sebaka sa ho mamella khoele.Tekanyetso ea naha e totobatsa sebaka se tloaelehileng sa mamello, joalo ka ha ho bontšitsoe ho Lethathamo la 9-4.Ka kakaretso, sebaka se khethiloeng sa mamello se boletsoeng tafoleng se lokela ho khethoa ka hohle kamoo ho ka khonehang.Khetho ea libaka tsa mamello e hlalositsoe khaolong ena.

(5) Bolelele ba screw le boemo bo nepahetseng

Bolelele ba screw screw e arotsoe ka mefuta e meraro: e khuts'oane, e mahareng le e telele, e bonts'itsoeng ke khoutu S, N le L, ka ho latellana.Litekanyetso li bontšoa ho Lethathamo la 9-5

Ha tekanyo ea mamello ea khoele e tsitsitse, ha bolelele ba sekoti se lelelele, ho ka ba holimo ho kheloha ha sekontiri se holimo le halofo ea leino ho kheloha ho ka ba teng.Ka hona, khoele ho ea ka boemo ba mamello le bolelele ba screw e na le mekhahlelo e meraro e nepahetseng: e nepahetseng, e bohareng le e thata.Tšebeliso ea boemo bo bong le bo bong bo nepahetseng bo hlalositsoe khaolong ena.Ka tekanyo e ts'oanang ea ho nepahala, boemo ba mamello ea khoele bo lokela ho fokotsoa ka ho eketseha ha bolelele ba ho ohla (sheba Lethathamo la 9-4).

(6) Ho tšoauoa ha likhoele setšoantšong ho bontšitsoe litabeng tse amehang tsa khaolo ena.

(7) Ho fumanoa ha likhoele ho arotsoe ka mokhoa o pharaletseng oa ho lemoha le ho lemoha ha motho a le mong.
