Nyob rau hauv tib neeg lub qhov muag feem ntau, bolts yog fasteners uas "ntsia tej yam ua ke" - ntev lawv, lawv muaj zog; cov thicker lawv, qhov ntau txhim khu kev qha lawv yog. Tab sis thaum koj muab ib lub koob yees duab siab -kawg lub koob yees duab, lub ntse saib, lossis txawm tias micro drone, koj yuav pom tias cov bolts siv sab hauv yuav tsuas yog 2-5 millimeters ntev, me dua li cov nplej nplej. Can zoo li "ultra- cov bolts luv" tiag tiag dais lub load? Dab tsi yog qhov txawv ntawm lawv thiab cov bolts zoo tib yam? Cov lus teb yog: lawv qhov txawv yog ntau tshaj li qhov ntev - qab lawv yog ib qho sib txawv kiag li ntawm engineering design philosophy.
I. Tshaj Length: Qhov txawv ntawm qhov tseem ceeb hauv kev tsim qauv
Ordinary bolts (xws li M6 × 20) feem ntau yog siv rau hauv cov xwm txheej xws li cov cuab yeej siv kho tshuab, cov qauv hlau, thiab lub tsheb chassis, tsom rau qhov siab ua ntej thiab muaj zog tensile thiab shear resistance. Lawv cov xov ntev, shank txoj kab uas hla, thiab lub taub hau zoo yog tsim los ntawm "load-cov kabmob" thiab "kev ruaj ntseg" - lawv tuaj yeem yooj yim disassembled thiab hloov yog puas. Ultra- cov bolts luv (xws li M1.4 × 2, M2 × 3), ntawm qhov tod tes, yog yug hauv ib puag ncig uas muaj qhov chaw tsawg heev. Hauv xov tooj ntawm tes motherboard brackets, optical lens modules, thiab micro motors, txhua qhov cubic millimeter yog qhov tseem ceeb heev. Lub sijhawm no, engineers tsis yog "xaiv bolts", tab sis "carving qhov chaw": cov xov yuav tsuas muaj 1-2 lem, ua tiav kev xauv los ntawm qhov haum; lub taub hau feem ntau siv lub qhov (socket) hexagon, ntoo khaub lig, los yog Torx (hnub qub) micro-slots, adapting rau micro electric screwdrivers; qee qhov txawm tshem tawm cov txiv ntoo ib txwm siv thiab ncaj qha mus rau hauv aluminium alloy lossis engineering yas lub cev. Ordinary bolts nrhiav "kev nyab xeeb tsis tu ncua", thaum ultra- cov ntsia hlau luv ua raws li "qhov kawg kev sib koom ua ke".
II. Force Logic: Los ntawm "Tensile-Based" mus rau "Friction + Interlocking" Coordination
Ib txwm ntsia liaj qhov rooj kev twb kev txuas cia siab rau qhov kev sib txhuam quab yuam tsim los ntawm axial preload los tiv thaiv transverse loads - lub tighter kojntsia hlau, lub firmer lub clamp. Txawm li cas los xij, ultra- cov bolts luv feem ntau tsis tuaj yeem tsim kom txaus preload: cov xov luv dhau, yog li nws hauv qab nrog ib qho twist; cov khoom sib txuas yog nyias dhau, yog li nws yuav plam lossis tawg yog tias siv zog ntau dua. Yog li ntawd, engineers tig mus rau "kev sib koom ua ke zoo": siv cov nplaum (xws li xov locker) los pab tiv thaiv -loosing; tso siab rau kev cuam tshuam haum ntawm cov khoom siv los yog qhov chaw pins kom dais lub ntsiab load; lub ntsia liaj qhov rooj nws tus kheej tsuas yog ua lub luag haujlwm "txoj haujlwm + txwv", tsis yog lub ntsiab lus tseem ceeb -cov kabmob. Hauv lwm lo lus: bolts zoo tib yam yog "cov players tseem ceeb", thaum ultra- cov bolts luv yog "qhov tseeb txhawb lub luag haujlwm" - lawv tsis nyiag qhov yeeb yam, tab sis tag nrho cov kab ke yuav poob sib nrug yam tsis muaj lawv.
III. Cov txheej txheem los ua ke: Los ntawm "Txuas Tightening" mus rau "Automated Micro-Kev Ua Haujlwm"
Ordinary bolts tuaj yeem ntsia tau nrog phau ntawv wrenches, phom pneumatic, lossis txawm tias cov cuab yeej hydraulic, nrog cov kev xav tau xoob ntawm kev ua haujlwm raug. Kev sib dhos ntawm ultra- cov bolts luv, txawm li cas los xij, feem ntau ua tiav los ntawm kev ua tiav tsis siv neeg lossis ib nrab - cov khoom siv tsis siv neeg precision: torque tswj yog qhov tseeb rau 0.01 N·m (sib npaug rau lub zog ntawm lub teeb kov); tus ntsia hlau me ntsis xav tau ib qho kev cai micro- txoj kab uas hla kom tsis txhob plam thiab ua rau cov khoom nyob ib puag ncig; kev sib dhos ib puag ncig feem ntau yog chav huv los tiv thaiv cov khoom me me txawv teb chaws los ntawm jamming cov xov. Thaum muaj kev ua haujlwm yuam kev tshwm sim, lub teeb tshwm sim yog bolt slipping thiab scrapping, thiab qhov tshwm sim loj yog ua rau lub rooj tsav xwm hloov tau yooj yim lossis sensor hauv qab - qhov poob tsis yog tus nqi ntawm ib lub ntsia liaj qhov rooj, tab sis tus nqi ntawm tag nrho cov motherboard.
IV. Qhov tseem ceeb sib txawv hauv Design Philosophy
Tom qab qhov no yeej yog kev sib tsoo ntawm ob txoj kev cai engineering: tsoos mechanical engineering hais txog "redundancy thiab kev nyab xeeb", nrhiav kev ruam tsis zoo; thaum niaj hnub precision manufacturing cov neeg tawm tswv yim "tsuas yog- txoj kev ua tau zoo", ua kom muaj nuj nqis nyob rau hauv qhov chaw txwv thiab tsis lees txais qhov tsis tsim nyog rov ua dua.
Xaus:Me Bolts, Txawj Ntse
Lwm zaus koj tuaj nqa koj lub xov tooj ntawm tes lossis saib ntse, xav txog nws: tej zaum yuav muaj kaum lub kaum ntse ntse - luv bolts tsawg dua 3 millimeters ntev muab zais rau hauv. Lawv tsis muaj zog txaus, tab sis nrog millimeter- theem precision, lawv txhawb lub siab -tech ntiaj teb nyob rau hauv peb txhais tes. Qhov tseeb kev zoo nkauj ntawm engineering tsis yog ib txwm nyob hauv cov qauv loj, tab sis qee zaum hauv qhov "me me" koj tsis tau pom.
Tswv yim: Yog tias koj koom nrog cov khoom tsim, kev tsim vaj tsev, lossis kev tsim khoom- ntsig txog kev ua haujlwm, koj yuav tsum tau ua tib zoo saib cov hauv qab no thaum xaiv ultra- cov bolts luv: cov khoom sib txuam (tsis txhob electrochemical corrosion), xov qhov tob thiab hauv qab qhov precision, thiab sib dhos torque nkhaus verification - cov ntsiab lus txiav txim siab ua tiav lossis tsis ua haujlwm.
