Screw Linear Modules

Screw Linear Module ke sesebelisoa sa mochini se etselitsoeng ho fana ka motsamao o nepahetseng oa mela ho li-automation le lits'ebetso tsa indasteri. E sebelisa sekoti{1}}haholo-holo sekorufu sa bolo kapa sekoti sa lead{2}}ho fetola motsamao o potolohang hore e be motsamao o otlolohileng{3}}moleng. Li-module tsena li sebelisoa haholo moo ho nepahetseng, ho pheta-pheta, le motsamao o laoloang o hlokahalang.

Screw Linear Modules ke lisebelisoa tsa bohlokoa tsa mochini tse sebelisoang ho laola motsamao oa mela ka tsela e nepahetseng le e sebetsang. Li na le screw ea loto, enjene, seporo sa tataiso le yuniti ea matlo. Bohareng ba moralo oa bona ke sekurufu sa lead, se fetolang motsamao oa ho potoloha ho tloha enjeneng ho ea ho motsamao o nepahetseng oa mola. Seporo sa tataiso se sebetsa ho netefatsa hore likarolo tse tsamaeang li tsamaea hantle ntle le ho kheloha ho sa hlokahaleng. Ntlo e fana ka ts'ehetso le ts'ireletso, e etsa hore mochini o tšoarelle le ho ts'epahala bakeng sa ts'ebeliso ea nako e telele-.

Sebopeho sa motheo sa Screw Linear Module se kenyelletsa "screw shaft" (ball screw or lead screw), motor (servo, stepper, kapa AC/DC), kopano ea linate, le sistimi e tataisang linear. Enjene e potoloha screw, e etsa hore nate e tsamaee ka bolelele ba eona, e sutumelletsa kapa e hula mojaro o khomaretsoeng. Li-module tse ngata li kenyelletsa li-sensor le li-control ho ntlafatsa ho nepahala ha maemo. Moralo oa tsona o momahaneng le o thata o li etsa hore li tšoanelehe-mesebetsi e mengata e phahameng ha li ntse li sebetsa ka thelelo.

Screw Linear Modulesli bohlokoa liindastering tse fapaneng. Ha ba etsa li-automation, ba beha lisebelisoa, ba kopanya likarolo, 'me ba tšoara thepa ka nepo. Indasteri ea semiconductor e itšetleha ka tsona bakeng sa ts'ebetso e bonolo ea li-wafer le litsamaiso tsa tlhahlobo. Lisebelisoa tsa bongaka, tse kang lisebelisoa tsa litšoantšo le lisebelisoa tsa ho buuoa ka robotiki, le tsona li sebelisa li-module tsena bakeng sa motsamao o laoloang. Ho feta moo, li fumanoa mecheng ea ho paka, mechini ea CNC, le bahatisi ba 3D, moo motsamao o pheta-phetoang o leng bohlokoa.

Ke mehato efe ea ho itšireletsa bakeng sa ho kenya le ho lokisa li-module tsa ball screw linear?

Ho kengoa le ho lokisa bothata ba mojule oa "ball screw linear" ho ama ka kotloloho ho nepahala ha bona, bophelo ba ts'ebeletso, le botsitso ba ts'ebetso. Hoa hlokahala ho ela hloko ka ho khetheha boemo ba mochini, ho leka-lekanya matla, le ho lekanya parameter. Litlhokomelo tse khethehileng ke tse latelang:

1. Tokisetso pele ho instola tse Screw Linear Module

1). Tlhahlobo ea likarolo

Sheba hore na screw e potoloha hantle (ntle le lerata kapa lerata le sa tloaelehang), haeba selaete sa seporo sa tataiso se tsamaea hantle, le haeba ho na le lintho tse tsoang linaheng tse ling tsamaisong ea potoloho ea bolo; Netefatsa hore mmotlolo oa mojule o tsamaellana le litekanyo tsa ho instola, 'me u netefatse hore na liparamente tse joalo ka lloto ea sekurufu le phalliso e reitiloe li fihlela litlhoko tsa moralo.

2). Kalafo ea motheo bakeng sa Screw Linear Module

Sebaka sa setsi sa ho kenya se lokela ho ba se bataletseng (phoso ea flatness Ka tlase kapa e lekanang le 0.1mm / m), e hloekile, 'me ha ho hlokahala, sebelisa sandpaper ho tlosa burrs; Haeba setsi e le karolo ea welded, e hloka ho fumana kalafo ea botsofali ho felisa khatello ea maikutlo le ho qoba deformation e amang ho nepahala ha module nakong e tlang.

2. Lintlha tsa bohlokoa tsa ho kenya mochine bakeng sa Screw Linear Module

1). Ho lokisa module

Sebelisa "mohato oa diagonal-ka{1}}mohato o tiisang" mokhoa oa ho lokisa mochine (joalo ka ho tiisa butle-butle liboutu tsa M6 ka 20% -50% -100% torque, torque e khothalletsoang 8-10N · m), ho thibela khatello ea maikutlo ea sebakeng seo ho baka deformation ea motheo; Sebaka sa ho kenya se lokela ho khomareloa ka thata ka tlase ho module, 'me lekhalo le ka hlahlojoa ka sekhahla sa feeler (e lokela ho ba ka tlase ho 0.02mm), ho seng joalo li-shims li hloka ho eketsoa bakeng sa phetoho.

2). Tekanyetso ea ho tšoana

Use a dial gauge to calibrate the parallelism between the module and the motion reference (error ≤ 0.05mm/m), ensuring that the screw axis is parallel to the guide rail and reducing additional torque; Long stroke modules (>1m) e hloka ho lekanyetsoa lipheletsong ka bobeli le lintlha tse tharo bohareng ho qoba ho kheloha ha motheo ho amang ho nepahala ka kakaretso.

3). Khokahano ea Drive

Ha motlakase le screw li hokahane ka ho kopanya, phoso ea coaxiality e lokela ho ba Ka tlaase ho kapa e lekanang le 0.1mm, 'me ho kheloha ha angle ho lokela ho ba Ka tlaase ho kapa ho lekana le 0.5 degree, e ka lekanyetsoang ho sebelisoa sesebelisoa sa laser alignment; Khetho ea ho kopanya e lokela ho lumellana le torque ea motlakase (hangata makhetlo a 1.5 ho feta torque e lekantsoeng) ho qoba ho tlala le ho senyeha.

4). Ho kenya moroalo

Bohareng ba matla a khoheli a mojaro o lokela ho lumellana le axis ea ho sisinyeha ha mojule, 'me eccentricity e lokela ho laoloa ka hare ho 5mm, ho seng joalo e tla eketsa mojaro oa radial holim'a seporo sa tataiso le ho eketsa ho apara; Ha u kenya ka holimo, hoa hlokahala ho kenya lisebelisoa tse thibelang ho oa (tse kang li-brake tsa electromagnetic, liloko tsa mechine) le ho hlahloba hore na mojaro o tsitsitse ha matla a khaotsoe.

3.Litlhaloso tsa taelo ea motlakase ea Screw Linear Module

1). Tlhahlobo ea lithapo

Mehala ea li-motor, li-encoder, le li-switches tsa moeli li lokela ho lumellana le litšoantšo, 'me li hanelle fatše tse ka tlase ho 4 Ω ho qoba ho kena-kenana le motlakase; Arola likhoele tsa likhoele tsa motlakase le likhoele tsa mats'oao (ka sebaka se seholo ho feta kapa se lekanang le 30cm) ho thibela ho kheloha ha maemo ho bakoang ke ho khopama ha matšoao.

2). Litlhophiso tsa parameter

Pele matla a pele a bulehile, netefatsa hore litekanyetso tsa mokhanni oa motlakase (joaloka hona joale, karohano, nako ea ho potlakisa) li bapisa motlakase ho qoba ho khathala ho feteletseng; Nakong ea ts'ebetso ea teko, qala ka ho beha lebelo le tlase (Ka tlase kapa ho lekana le 50mm/s) le ho potlakisa ho honyane (Ka tlase kapa ho lekana le 1m/s²), 'me u shebe hore na motsamao o boreleli.

3). Fokotsa tekano

Fetola moeli oa mochine kapa boemo ba ho fetola motlakase oa lifoto ho netefatsa hore ho na le moeli oa 5-10mm lintlheng tse peli tsa stroke ho thibela ho thulana ho matla; Ka ho beha meeli e bonolo ea moeli ka molaoli, e sebetsa e le tšireletso e 'meli bakeng sa moeli oa mochine.

4. Ho nepahala le ho lekoa ha Screw Linear Module

1). Puseletso ea lekhalo

Sebelisa laser interferometer ho lemoha clearance reverse (hangata E ka tlase ho kapa e lekana le 0.01mm), 'me haeba e feta mamello, e ka lefshoa ka ho tiisa pele nut (sebopeho sa linate tse peli) kapa li-parameter tsa controller; Lekola ho nepahala ha boemo ka lebelo le fapaneng (joalo ka 200mm/s, 500mm/s) ho netefatsa hore phoso ea lebelo lohle e ka har'a sebaka se lumelletsoeng.

2). Etsa liteko

Matha ka mokhoa o tsoelang pele ka metsotso e 30, hlokomela mocheso oa motlakase le screw (e lokela ho ba ka tlase ho kapa e lekanang le likhato tse 60), 'me haeba e chesa haholo, hlahloba hore na mojaro o feta moeli kapa hore na lubrication e lekane; Ela hloko lerata la ts'ebetso (e tlameha ho ba ka tlase ho 65dB), lerata le sa tloaelehang le ka bakoa ke ho kheloha ha likhokahano kapa ho roala ha bolo, 'me mochini o hloka ho emisoa bakeng sa ho rarolla mathata.

5.Malebela a tlhokomelo ka mor'a ho kenya Screw Linear Module

Pele ho ts'ebetso ea pele, eketsa grease e khethehileng ea ho tlotsa (lithium e thehiloeng grease NLGI grade 2) ho sekoti sa lead, 'me u ente oli e tlotsang (ISO VG32) ka har'a slide sa terene ea tataiso; Rekota lintlha tsa ho kenya le ho lokisa liphoso (joalo ka ho bapisa le ho nepahala ha maemo) joalo ka litšupiso bakeng sa tokiso ea morao-rao.

Ka ho laola ho nepahala ha ho kenngoeng (haholo-holo ho bapisa le coaxiality) le mohato-ka-ho lokisa bothata, phoso ea boemo ba Screw Linear Module e ka laoloa ka har'a 80% ea boleng ba moralo, 'me nako ea bophelo e ka eketsoa ho feta makhetlo a 1.5.
