Me ka hoʻomohala ʻana o nā kaʻa a me kā lākou ʻenehana hoʻokele kaʻa, nā spindles uila, nā kaʻa laina, nā motika torque a me ka hoʻonui ʻana o ka ʻenehana, i hiki ai i ka spindle, linear a me rotary coordinate motion o ka manaʻo "direct drive" i ka ʻoiaʻiʻo, a hōʻike nui aʻe. kona kiekie nui. ʻO ka mīkini laina laina a me kāna ʻenehana hoʻokele kaʻa i ka mīkini meaʻai hānai ma ka noi, no laila ua hoʻololi nui ka hoʻololi ʻana o ka mīkini mea hana a hana i kahi lele hou i ka hana mīkini.
ʻO kaMainApono oLinearMotorFeedDrive:
ʻO ka nui o ka wikiwiki o ka hānai: Hiki ke mai 1 (1) m / s a ʻoi aku ma mua o 20m / min, ʻo ke kikowaena mīkini ʻenehana i kēia manawa ua hiki i ka 208m / min, ʻoiai ʻo ka mīkini hana kuʻuna wikiwiki wikiwiki <60m / min. , maʻamau 20 ~ 30m / min.
ʻO nā hiʻohiʻona wikiwiki maikaʻi: Hiki ke hōʻea i ka (1) 0.01% a i ʻole ka liʻiliʻi.
ʻO ka wikiwiki nui: ʻO ka wikiwiki o ka mīkini laina laina a hiki i ka 30g, ʻo ka wikiwiki o ka meaʻai machining center i kēia manawa ua hōʻea i 3.24g, ua hiki i ka 5g ka wikiwiki o ka mīkini hoʻomaʻamaʻa laser, aʻo ka wikiwiki o ka mīkini mea hana maʻamau i 1g a i ʻole, maʻamau 0.3g.
Ke kūlana kūlana kiʻekiʻe: ʻO ka hoʻohana ʻana i ka mana paʻa paʻa paʻa, hoʻonohonoho pololei a hiki i 0.1 ~ 0.01 (1) mm. hiki i ka hoʻohana ʻana i ka mana feed-forward o ka ʻōnaehana kaʻa kaʻa linear ke hōʻemi i ka hala ʻana ma mua o 200 mau manawa. Ma muli o nā hiʻohiʻona maikaʻi o ka neʻe ʻana o nā ʻāpana a me ka pane koʻikoʻi, i hui pū ʻia me ka hoʻomaʻamaʻa ʻana o ka mana interpolation, hiki ke hoʻokō i ka mana nano-level.
ʻAʻole i kaupalena ʻia ka huakaʻi: Ua kaupalena ʻia ke kaʻina o ka wili pōpō kuʻuna e ka hana ʻana o ka wili, ma ke ʻano he 4 a 6m, a ʻoi aku ka nui o nā hahau e pono e hoʻopili i ka wili lōʻihi, mai ka hana hana a me ka hana ʻaʻole kūpono. ʻO ka hoʻohana ʻana i ka kaʻa kaʻa laina, hiki ke lōʻihi ka stator, a maʻalahi ke kaʻina hana, aia nā kikowaena mīkini kiʻekiʻe kiʻekiʻe X-axis a hiki i 40m ka lōʻihi a ʻoi aku paha.
Holomua oLinearMotor aIts DriveControlTʻenehana:
ʻO nā kaʻa laina laina like me nā kaʻa maʻamau i ka manaʻo, ʻo ia wale nō ka hoʻonui ʻana o ka ʻili cylindrical o ka kaʻa, a ʻo kona ʻano like me nā kaʻa kuʻuna, e like me: DC linear motors, AC permanent magnet synchronous linear motors, AC induction asynchronous nā motika laina, nā motika laina stepper, etc.
E like me ka linear servo motor hiki ke hoʻomalu i ka pololei o ka neʻe i ʻike ʻia i ka hopena o 1980s, me ka hoʻomohala ʻana o nā mea (e like me nā mea magnet mau loa), nā mana mana, ka ʻenehana mana a me ka ʻenehana ʻike, ke hoʻomau nei ka hoʻomaikaʻi ʻana o nā mīkini servo linear. ke emi nei ke kumukūʻai, e hana ana i nā kūlana no kā lākou noi ākea.
I nā makahiki i hala iho nei, ke holomua nei ka ʻenehana linear a me kāna ʻenehana hoʻokele kaʻa i nā wahi aʻe: (1) hoʻomau ka hoʻomaikaʻi ʻana i ka hana (e like me ka thrust, speed, acceleration, resolution, etc.); (2) ho'ēmi leo, ho'ēmi mahana; (3) kahi ākea ākea e hoʻokō i nā koi o nā ʻano mea hana mīkini; (4) ka hāʻule nui o ke kumukūʻai; (5) hoʻokomo maʻalahi a me ka pale; (6) hilinaʻi maikaʻi; (7) komo pū me nā ʻōnaehana CNC I ka ʻenehana kākoʻo e lilo i mea maikaʻi loa; (8) kiʻekiʻe kiʻekiʻe o ke kālepa.
I kēia manawa, ʻo nā mea hoʻolako nui o ka honua i nā kaʻa servo linear a me kā lākou mau ʻōnaehana hoʻokele: Siemens;Iapana FANUC, Mitsubishi; Anorad Co.(USA), Kollmorgen Co.; ETEL Co. (Switzerland) etc.
