Robotic welding fixture dhizaini haisi yekusungirira zvikamu mundiro. Ndezvekubvisa musiyano iro robhoti risati rambofambisa axis yayo yekutanga. Takaona mitsara yakawanda yekugadzira ichimira-kwete kubva kumarobhoti ane mhosva kana waya yakaipa-asi nekuti chigadziriso chinorega chikamu chichichinja 0.12 mm panguva yekubata. Kutsauka kudiki ikoko kunosanganisa 300 welds, kushandura zita rekuti ± 0.5 mm kushivirira kuita chiyero chakaraswa pamusoro pe18%. Precision inotangira panosangana simbi.
Nei "Zvakanaka Zvakakwana" Zvigadziriso Zvichikundikana Pasi Otomatiki
Manual welding inobvumira kushandiswa kwevashandi. Welder ane hunyanzvi anotsiva chikamu chidiki chekufamba, anogadzirisa kona yetochi pa-kubhururuka, uye anoverenga kukanganiswa kwemafuta semutauro wemuviri. Marobhoti haachinji-anodzokorora. Kana yako robhoti welding inoshaikwa inodzokororwa yekuwana nzvimbo, inopindirana clamping simba kugovera, kana kupisa kwekuwedzera muripo, hausi automating weld mhando-uri automating kusawirirana.
Isu tinogara tichiongorora zvigadziriso zvinounzwa neTier-1 vatengesi vemotokari. The akajairika kukundikana pfungwa? Pin-ne-bush locators inopfekwa kupfuura ISO 2768-mK miganho. Chitubu-chakaremerwa mabhanhire ane 22% simba rekuora mushure me4,000 kutenderera. Mabase plates akamonyoroka kubva mukupisa kusingaenzaniswi-kuyerwa kusvika pa 0.35 mm kutsauka pane 1.2 m span. Idzi hadzisi nyaya dzekupedzisira. Iwo ndiwo zvikonzero zviri kumashure kwe63% yekutanga-chinyorwa rework yatinoona mukutangwa kwechirongwa chitsva.
Kuita chaiko kwepasirese kunoda zvinopfuura kurongeka kweCAD. Zvinoda kunzwisisa kuti simbi inotonhorwa inokwidziridzwa sei pa12.5 µm/m·°C maringe nestainless pa17.3 µm/m·°C—uye kugadzira matendere enzvimbo dzinogara zvose pasina kuunza kushushikana kweparasitic. Zvinoreva kudoma akaomeswa 60 HRC dowel pini panzvimbo peyakajairwa 45 HRC mapini kana kutenderera kuverengwa kuchipfuura 50,000. Zvinoreva kuonesa kudzvanya kudzvanywa pa square millimeter - kwete kungozara tonnage - uchishandisa calibrated mutoro maseru panguva yekufanirwa.
Zvina Zvisina Kukurukurirana Fixture Design Principles
Yese yakakwirira-yakavimbika marobhoti welding gadziriso yatinovaka inoteedzera iyi-munda-yakapupurirwa mitemo:
Matatu-Point Kuwana, Kwete Ina: Kunyanya-kumanikidza kunokonzera kusunga. Isu tinoshandisa kinematic mounting: mapini maviri akajeka-pasi dowel + imwe yakati sandara pamusoro, ese akasimbiswa neCMM achipesana neGD&T callouts-kwete chete madhindindi edimensional. Clamp Force> Thermal Kuwedzera Simba: Pakupisa kwepamusoro weld tembiricha (kusvika 1,400 ° C pane nugget), base yekuwedzera zvinhu inogona kugadzira 1,200 N ye lateral simba pane 300 mm bracket. Zvisungo zvedu zvinounza ≥2.5 × iyo shoma inobata simba, yakayerwa zvine simba-kwete statically-pa 120 ° C ambient. Modular Interface, Kwete Monolithic Kuvaka: Nguva yekuchinja inouraya ROI. Isu tinosanganisa yakamisikidzwa ISO 841-3 yekumisikidza mapatani uye nekukurumidza-kubvisa mitsara inotonhorera. Avhareji yekuchinja inodonha kubva pa92 maminetsi kuenda pasi pemaminetsi gumi nemana munzvimbo gumi nenomwe dzevatengi. Weld Spatter Management seCore Function: Spatter haisi marara - inokanganisa kusvibiswa. Isu tinonyudza nhovo dzemhangura-yakavharwa, inotsiviwa ne spatter yakananga mumitumbi yakasungirirwa uye toiwana mukati me8 mm yenzvimbo yega yega weld. Data yemunda inoratidza izvi zvinocheka tochi yekuchenesa frequency ne70% uye inowedzera hupenyu hunodyiwa ne2.3 ×. Kuchinja Kwezvinhu Kunochinja Zvinhu Zvose
Aluminium zvigadziriso zvinotaridzika zvakapfava-asi zvinokundikana nekukurumidza munzvimbo dzepamusoro-basa-kutenderera. Isu takatevera zviuru gumi zvemaawa ekushanda mumhuri nhatu dzezvinhu:
Yakaomeswa 4140 Simbi (28–32 HRC): Yakanakira>200,000-kutenderera zvirongwa. Dimensional kugadzikana inobata mukati me ± 0.015 mm pamusoro pemwedzi gumi nemisere-kunyangwe nemazuva ese ekupisa bhasikoro. Stainless 17-4PH (H900): Inofarirwa kune chikafu-giredhi kana nharaunda dzinoora. Inochengetedza kurongeka kwenzvimbo mushure memaawa zviuru zvishanu zvekupfapfaidza munyu-asi inodhura 3.2× kupfuura 4140. Kandira Simbi EN-GJS-600-3: Inoshandiswa chete kumagungano makuru-akakura (> 2.5 m). Inoderedza vibration zvirinani pane simbi-asi inoda 72-awa yekushushikana yekuzorodza annealing post-machining. Hatimbotauri zvinhu zvinoenderana nemutengo chete. Kana mutengi akatikumbira kuchinja kubva pa4140 kuenda kualuminium kuchengetedza $1,200 pamutambo, takamhanyisa mutyairi wemwedzi mitatu. Mhedzisiro: 4.8% kuwedzera kwe weld porosity, 11% yepamusoro maelectrode kushandiswa, uye 3.2 mamwe ekugadzirisa anomira pakuchinja. "Kuchengeta" kwakanyangarika muvhiki yechipiri.
Botou Haijun's Fixture Validation Protocol
Zvigadzirwa zvedu zvinotakura nehumbowo hwakanyorwa-kwete zvivimbiso. Yese unit inopinda:
Pre-assembly CMM ongororo yezvese nzvimbo dzelocator (ASME B89.1.10M-2018 inoenderana) Clamp simba remepu kuyambuka yakazara yekufamba rwendo uchishandisa piezoelectric sensor grids Thermal kutenderera kuyedzwa: makumi mashanu kutenderera kubva pa20 ° C kusvika 180 ° C, kuyera locator kudonha pane imwe neimwe yakanyanyisa. Kugadzira-mutsara wakaoma-run: mazana maviri akateedzana matenderedzwa ane chaiwo zvikamu, anotariswa kuburikidza ne laser displacement sensors. Izvi hazvisi pamusoro-engineering.
