Paunonzwa 'hardware clamping fixture', vanhu vazhinji vanobva vangotora mifananidzo iri nyore kana jig yakakosha. Ndiyo yekutanga kusanzwisisa. Muchokwadi, ndiyo yakanyarara, kazhinji yakavakirwa-yakavakirwa musana yechero yakakomba machining kana kukanda basa. Hazvisi zvekungobata chikamu; ndezvekuibata ne zero deflection pasi pekucheka kunorema, nekugadzikana kwekupisa panguva refu, uye nekudzokorora kutenderera chiuru. Ita izvi zvisizvo, uye chikamu chako chekushivirira chakakura, zvisinei kuti CNC yako kana maitiro ako ekukanda akanaka sei. Ndakaona zvitoro zvakawandisa zvichidyara muchina wehafu-miriyoni yemadhora uye wobva wakanganisa ne $500 fixture.
Beyond the Blueprint: Ichokwadi cheFixture Dhizaini
Iyo theoretical dhizaini paCAD skrini ingori pekutanga. Iwe unogona kutsanangura simbi yakaoma hardware clamping fixture nemapini ekutsvaga echokwadi uye hydraulic clamps, asi bvunzo chaiyo inouya neyekutanga chip. Semuyenzaniso, patakanga tichigadzira chigadziriso chekukandira turbine blade panzvimbo yedu, modhi yeCAD yaitaridzika zvakanaka. Kukandwa kwaive nickel-based alloy kubva kumutengi aishandisa Investment casting kuti uwane fomu rekutanga. Basa redu rakanga riri rokupedzisira nemazvo machining.
Mutambo wekutanga wakabata chimiro chemhepo zvakanaka. Asi isu hatina kuverengera kune yasara kushushikana mukukanda. Mushure mekupfuura kwekutanga kugayo, chikamu chakachinjika zvidiki sezvo kushushikana kwemukati kwakadzikira. Zvakaguma nei? Chikamu chakanaka, chinopenya, uye chiri kunze-che-chete. Chigadzirwa chacho chakanga chisina kukanganisa; hazvina kupindirana nehuchokwadi hwezvinhu. Isu taifanira kudzoka, kuwedzera zvitsigiro zvekuwedzera munzvimbo dzewebhu kuti titange kurodha uye kudzikamisa chikamu chisati chachekwa, kwete kungochibata muchimiro chayo chezita.
Apa ndipo panokundikana generic fixtures. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ine makumi matatu emakore mukati CNC machining uye kukanda, anoona kusangana uku zuva nezuva. Iwe haugone kupatsanura chigadziriso kubva munhoroondo yezvinhu - ingave iri simbi yakakasharara yekugadzira kana yakatetepa. shell mold casting. Iyo gadziriso inofanirwa kubhadhara iyo nhoroondo.
Nyaya ndiyo Mharidzo
Fixture strategy inoshanduka zvachose ne substrate. Kusunga imba ye ductile iron? Iwe unogona kuve nehasha zvakaringana ne clamping forces. Asi chinja kune cobalt-based alloy kana yakatetepa-yakavakirwa simbi isina chinhu chikamu, uye mutambo wakasiyana. Yakawandisa poindi kurodha kubva kune clamp inogona kukanganisa chikamu usati watombotanga, kana zvakanyanya, shanda-kuomesa nzvimbo yenzvimbo uye kuparadza hupenyu hwekushandisa.
Kune izvi zvinhu zvinonyengera, isu tinowanzo shandisa kinetic kukwira kana vacuum zvigadziriso. Ndinoyeuka bhechi remahwendefa mahombe, akati sandara asina tsvina aida kugayiwa. Yechinyakare yepamusoro-clamp fixture ingadai yakakonzera dome mhedzisiro. Takapedzisira tashandisa modular vacuum plate system, asi kunyangwe zvakadaro, chisimbiso chaifanira kunge chakakwana. Kudonha kudiki pane imwe kona kwaireva kuti chikamu chaigona kusimuka panguva yekumhanya-mhanya kupedzisa kupfuura. Ndiwo maminetsi aya - iyo gasket zvinhu, kupedzisa kwepamusoro kweplate yekugadziridza pachayo - inoita kana kuputsa basa. Hazvinakidzi, kugadzirisa matambudziko.
Iyi ruzivo-yakanangana nezvinhu yakakosha. Uchitarisa QSY's portfolio, iyo inotenderera kubva kusimbi yakakandwa kuenda kune yakakosha alloys, unoziva magadzirirwo avo haasi akaenzana-anokodzera-ese. The hardware clamping fixture nokuti muviri wesimbi inorema vharafu ichava chikara chine hutsinye, chakaoma. Iyo yemuchina wekudyara-yakakanda aerospace bracket ichave inoyevedza, ine zvishoma intrusive dancer. Ose ari maviri anofanira kunge akaenzana.
Kubatanidzwa neCasting Processes
Iyi ipfungwa huru inowanzofuratirwa. Iyo yakanakisa dhizaini dhizaini dzimwe nguva inotanga chikamu chisati chatombokandwa. Mune shell mold uye kukanda kwekudyara, iwe une mukana wekugadzira inosanganisirwa fixture maficha. Takashanda pamapurojekiti atakagadzira mabhegi ekukanda kana madhamu munzvimbo dzisiri dzakakosha dzechikamu. Aya anobva ashandiswa senzvimbo dzekutanga dzekutsvaga uye dzekuvhara panguva yekugadzira, uye anozopedzisira agadzirwa mukushanda kwekupedzisira.
Iyo inogadzira yakavharwa-loop maitiro: iyo yekukanda maitiro inogadzira yayo yakakwana mareferenzi mapoinzi ekugadzira. Izvi zvinobvisa iyo yakapetwa kaviri datum kukanganisa, kwaunoyedza kunyoresa nzvimbo yakashongedzwa kune yakaparadzana, isina kukwana yakakandwa nzvimbo. Zvakaipa? Zvinoda kubatana kwakadzama pakati peiyo yekutanga uye shopu yemuchina kubva padanho rekugadzira. Haisi kungotenga gadziriso kubva pakatalogi; ndiko engineering kutevedzana kwekugadzira.
Kune vertical integrated operation, iyi mukana wakakura. Kambani inobata zvese kukanda uye machining, seQSY, inogona kukwirisa iyi loop. Ivo vanogona kusarudza kana chimiro chiri nani kukanda-kusvika-saizi kana kugadzirwa, uye gadzira iyo hardware clamping fixture zano zvinoenderana, kuponesa mutengi kubva kunodhura iterations.
The Failure Museum: Kudzidza kubva kune Chii Chakaputsa
Chero akavimbika machinist kana tooling engineer ane museum yepfungwa yekutadza. Imwe inomira neni yaisanganisira modular fixture system yataive tiine chivimbo zvikuru mairi. Taiva nemhuri yedzimba dzakafanana dzealuminium. Pfungwa yaive yekushandisa yakajairwa baseplate ine zvinochinjika nzvimbo uye zvisungiriro. Papepa, yaibudirira.
Mukuita, iyo yakawedzera kushivirira stack ye modular zvikamu - baseplate flatness, dowel pini maburi, iyo adapta mahwendefa - yakauraya kudzokorora kwedu. Chikamu 1 chingave chiri mukati meiyo spec, chikamu 50 chingave chichidonha. Iyo gadziriso pachayo yakanga yava sosi yekusiyana. Isu takarasa iyo inoshanda modular nzira yebasa iro uye takavaka yakatsaurwa, monolithic zvigadziriso zvechikamu chimwe nechimwe chakasiyana. Mutengo wepamberi waive wakakwira, asi mwero wezvikara wakaenda ku zero. Chidzidzo chacho? Dzimwe nguva, kutsvaga kuchinjika muvengi wekurongeka. A akazvitsaurira hardware clamping fixture, nepo isinganyanyi kunakidza, inowanzova chishandiso chakavimbika kwazvo pasi.
Kumwe kutadza kwekirasi kurerutsa kutonhorera uye chip kuyerera. Iwe unogadzira iyi yakanaka, yakaoma gadziriso inoputira zvizere chikamu chekuomarara. Zvino, pakumhanya kwekutanga, machipisi anorongedza mune yega yega, inotonhorera haigone kuiburitsa kunze, uye chikamu chinokwarwa, kana zvakanyanya, machipisi akatakurwa anoshandura simba rekumanikidza. Ikozvino wave kumisa kutenderera kwega kwega maminetsi gumi kuti ufuridze chigadziriso. Iyo dhizaini inofanirwa kuverengera kukanganisa kweiyo chaiyo-yenyika machining.
Izvo zvisingagoneki: Kunzwa uye Iteration
Chekupedzisira, pane chinongedzo kune ichi chisingamboite kuti chiite pepa rekufungidzira: kunzwa kwechimiro chakanaka. Paunoisa chikamu muchigadziriso chakanyatsogadzirwa, chinofanira kugara chine yakasimba, yakanaka clunk, kwete inozeza inotsvedza. Iwo machira anofanirwa kuita mushe, pasina iwe unofanirwa kurwa nawo. Unogona kunzwa kuoma.
Izvi zvinobva pakudzokorora. Yekutanga vhezheni yechigadziriso kashoma yekupedzisira. Iwe unogona kuwedzera tsigiro mushure mekuona zvishoma chatter chiratidzo. Unogona kushandura chibatiso kubva paruoko rwekuzunguza kuenda kuchisundidzira-kudhonza dhizaini kuti ikurumidze kurodha. Kudzokorodza uku ndiko kunoratidzwa chiitiko chinoshanda chechitoro chenguva refu. Haisi nyaya yekugadzira chigadziriso chete; ndezvekugadzira mhinduro inoshanda padivi peiyo machining process pachayo.
Pakupedzisira, a hardware clamping fixture ndiwo mufananidzo chaiwo weruzivo rwemaitiro. Ndiko uko kushivirira kwedzidziso kunosangana nekudengenyeka, kupisa, chip-chakazara chokwadi chepasi rechitoro. Kunyangwe iri yemhando yepamusoro-vhoriyamu yemotokari chikamu kana imwe-yega prototype mune nickel alloy, budiriro yayo haisi yekungobata chikamu. Zviri mukugonesa muchina uye mhizha kuita basa ravo rakanakisa, nekuvimbika, nguva nenguva. Ndizvo zvauri kunyanya kuisa mari mazviri.
