Lub tsev DIY Rhino lub laub tsis yog hais txog kev luam ib daim ntawv teev npe - nws yog hais txog kev daws teeb meem ntawm kev cob qhia tiag tiag nrog qhov tseeb, lub zog, thiab rov ua dua. Peb tau pab ntau tshaj 37 tus neeg siv khoom tsim thiab siv tau cov rooj zaum vuam kev cai txij li xyoo 2021. Nyob rau hauv txhua rooj plaub, qhov pib tsis yog qhov zoo nkauj lossis nrawm. Nws yog load stability nyob rau hauv 45 ° qaij, weld-joint qaug zog lub neej ntawm 12,000 cycles, thiab seb lub caster mounting phaj yuav ciaj sia rov 80-kg cuam tshuam poob thaum lub sij hawm mobile fabrication. Tias yog vim li cas "DIY Rhino lub laub" kev tshawb nrhiav tau nce 220% hauv North America xyoo tas los - tsis yog rau kev nyiam ua, tab sis rau thaj chaw siv tau, OEM-qib txhawb nqa platforms.
Vim li cas "Rhino" Tsis yog Kev Lag Luam nkaus xwb-Nws yog Tus Qauv Qauv
Qhov tseeb rhino vuam lub laub lub rooj yuav tsum ua tau raws li peb qhov kev sib tham tsis tau: nruj torsional kuj, repeatable qhov siab xauv, thiab integrated grounding continuity. Feem ntau cov tsheb laij tawm ntawm lub txee tsis ua ntej. Peb tau sim 14 chav ua lag luam hauv peb lub chaw sim Botou siv ISO 14122-3 cov txheej txheem poob. Cuaj deformed ntawm lub hauv paus ncej sib koom ua ke thaum loaded nrog ib tug 60-kg MIG welder thiab 30-m cable reel. Hom tsis ua hauj lwm? Nyias-gauge sab rails twisting nyob rau hauv lateral torque thaum lub log articulation.
Qhov ntawd yog qhov kev xaiv cov ntaub ntawv txiav txim siab. Cold-rolled steel (CRS) Q235B muaj kev pom zoo-rau-tus nqi piv rau cov qauv thav duab-235 MPa yam tsawg kawg nkaus, 370-500 MPa tensile, nrog nruj tuab kam rau ua (± 0.08 hli). Stainless 304 ua haujlwm rau corrosive ib puag ncig tab sis txi 30% nruj rau ib chav tsev qhov hnyav. Aluminium 6061-T6 txiav qhov hnyav los ntawm 60% tab sis yuav tsum tau 2.3 × tuab seem kom phim CRS torsional rigidity. Peb cov ntaub ntawv pov thawj pom tau tias CRS xa 92% tsawg dua thav duab deflection dua li cov txhuas sib npaug ntawm cov ntsiab lus sib npaug.
Cov Txheej Txheem Tsim Nyog—Qhov Ua Tau Zoo Li Cas
Tsis nco qab "ib kauj ruam ntawm kev qhia YouTube." Kev sib dhos tiag tiag hauv ntiaj teb xav tau kev qhuab ntuas ntu. Nov yog qhov peb tswj hwm hauv txhua tus neeg siv khoom tsim spec:
Ncej thawj-tsis muaj kev zam. Weld lub duab plaub loj (1200 × 600 mm) ua ntej muab cov hlaws dai. Siv 3-mm CRS phaj rau ob txhais ceg, 2.5-mm rau sab saum toj lawj. Clamp tag nrho cov ces kaum rau granite nto phaj; txheeb xyuas kab pheeb ces kaum tsis pub dhau 0.3 hli sib txawv ua ntej tack-welding. Caster mounts mus kawg - tsis yog thawj zaug. Laum thiab coj mus rhaub M12 × 1.75 threaded inserts * tom qab * tag nrho cov ncej kev ntxhov siab-relief annealing. Pre-drilling ua ntej vuam guarantees misalignment thaum tshav kub distortion tshwm sim. Grounding tsis yog kev xaiv xaim-nws yog txoj hauv kev sib koom ua ke. Khiav ib 6-AWG tooj liab pluaj los ntawm lub ntsiab ncej mus rau txhua lub tsev caster, ces mus rau lub vuam tshuab lub hauv av lug. Kev ntsuas tsis kam: ≤0.1 Ω thoob plaws lub voj voog. Yog tsis muaj qhov no, lub suab nrov nrov cuam tshuam cov welder tawm tswv yim loops. Peb tau pom 68% ntawm DIY ua tsis tiav rov qab los hla cov kauj ruam kev ntxhov siab. Ib tus neeg siv khoom hauv Wisconsin tau khiav 300 teev ntawm kev tsim khoom ntawm ib lub laub uas tsis muaj kev cuam tshuam ua ntej nrhiav pom 1.2 hli cumulative ceg hneev - txaus los muab pov tseg ntawm laser-guided part positioning.
Thaum twg rau Outsource-Thiab yog vim li cas Precision Matters ntau dua tus nqi
Qee cov khoom tiv thaiv qhov chaw nres tsheb-qib qhov tseeb. Bent bracket caj npab xav tau ± 0.2 ° angular kam rau ua kom ntseeg tau tias kev sib tw tsheb ciav hlau. Sib sib zog nqus caster khob yuav tsum muaj cov phab ntsa tuab (± 0.1 hli) los tiv thaiv kev sib hloov eccentric. CNC xovxwm brakes ua tiav qhov no. Tes-bending nrog ib lub yeeb nkab vise tsis.
Botou Haijun Hlau Khoom Co., Ltd. tsim cov khoom no rau OEMs thoob ntiaj teb vim tias lawv cov chaw ua haujlwm ISO-raws li CMM kuaj xyuas ntawm txhua pawg-thiab muab cov ntawv qhia txog kev sim nrog txhua cov khoom xa tuaj. Lawv qhov yooj yim-batch me me txhais tau tias koj tau txais 5 qhov kev cai hauv 12 hnub, tsis yog 500 hauv 6 lub lis piam. Tsis muaj MOQ. Tsis muaj tus nqi cuab yeej rau kev tsim qauv hauv qab 3 kev hloov kho. Kev tawm tswv yim engineering tuaj txog hauv 72 teev - tsis yog "hauv hnub ua haujlwm."
Qhov no tsis yog outsourcing yooj yim. Nws yog kev pheej hmoo hloov tsheb. Thaum koj lub laub txhawb nqa $ 28,000 tus nqi ntawm cov khoom siv hluav taws xob robotic, 0.5 ° misalignment nyob rau hauv lub mounting bracket nqi ntau dua nyob rau hauv downtime tshaj tag nrho cov bracket teem.
Qhov kawg validation—Lub 5-feeb Field Test uas cais Rhino los ntawm Rhino-Lookalike
Ua ntej thauj cov cuab yeej, khiav cov txheej txheem no:
Xauv tag nrho plaub casters. Siv 150 kg static load ntawm nruab nrab ntawm lawj. Ntsuas deflection:> 1.5 hli = tsis txaus bracing. Xauv casters. Thawb lub laub rau sab ntawm 1.2 m / s mus rau hauv ib qho chaw ruaj khov. Tshawb xyuas weld seams hauv qab 10 × magnification: xoom micro-cracks = dhau. Txuas grounded welder. Ntsuas qhov voltage ntawm workpiece clamp thiab cart ncej: <0.3 V AC ntawm 200 A tso zis = kev sib raug zoo. Tig lub laub 30 ° rau pem hauv ntej. Tuav rau 60 vib nas this. Tsis muaj ceg slippage lossis caster wobble = ruaj khov nruab nrab ntawm lub ntiajteb txawj nqus. Rov ua cov kauj ruam 1-4 tom qab 8 teev ntawm kev siv tas li. Tib yam tshwm sim? Koj tau ua ib lub rooj rhino welding lub rooj. Feem ntau DIY sim ua tsis tiav ntawm qib 2 lossis 4. Qhov kho tsis muaj zog hlau - nws yog qhov tseeb lub sij hawm-arm geometry thiab cov khoom pov thawj. Tias yog vim li cas "diy rhino cart" tshawb nrhiav txuas ntxiv nrog "cov ntawv xa khoom zoo" thiab "lub laub vuam CAD tshuaj xyuas."
Lub rooj rhino welding lub rooj tau txais nws lub npe los ntawm kev ntsuas kev ua tau zoo - tsis yog hom khoom lag luam. Nws txav cov khoom hnyav yam tsis muaj thav duab flex, ua rau lub suab nrov nrov yam tsis muaj kev cuam tshuam, thiab ua rau muaj kev cuam tshuam hauv khw hauv pem teb yam tsis muaj vuam qaug zog. Tsim kom raug, thiab nws kav 15 xyoo. Ua kom ceev ceev, thiab koj yuav rov tsim nws lub hlis tom ntej. Koj qhov kev xaiv txhais lub laub-thiab koj qhov kev ntseeg tau raws li tus neeg tsim khoom.
