CNC muchina maturusi ari kusimukira munzira yekurongeka, kumhanya kwakanyanya, komputa, hungwaru uye kuchengetedza kwezvakatipoteredza. Kurongeka uye kumhanyisa machining kunoisa zvakakwirira zvinodikanwa padhiraivha uye kutonga kwayo, yakakwirira simba hunhu uye kutonga kurongeka, yakakwira chiyero chekudya uye kukwidziridza, yakaderera vibration ruzha uye kushoma kupfeka. Iyo crux yedambudziko ndeyekuti yechinyakare yekutapurirana cheni kubva kumota senge sosi yemagetsi kune nzvimbo dzinoshanda kuburikidza negiya, worm giya, mabhandi, screws, couplings, clutches uye mamwe epakati ekutapurirana malink, mune aya malink akagadzira yakakura inotenderera inertia. , elastic deformation, backlash, motion hysteresis, friction, vibration, ruzha uye kupfeka. Kunyangwe munzvimbo idzi kuburikidza nekuenderera mberi kwekuvandudza kuvandudza mashandiro ekutapurirana, asi dambudziko rakaoma kunyatsogadzirisa, mukubuda kweiyo pfungwa ye "direct transmission", ndiko kuti, kubviswa kweakasiyana-siyana epakati links kubva kumota kuenda kunhengo dzinoshanda. . Nekuvandudzwa kwemamota uye tekinoroji yavo yekudzora tekinoroji, maspindle emagetsi, linear motors, torque motors uye kuwedzera kukura kwetekinoroji, kuitira kuti spindle, mutsara uye inotenderera irongedze kufamba kweiyo "direct drive" pfungwa kuita chokwadi, uye inowedzera kuratidza. hukuru hwayo hukuru. Linear mota uye tekinoroji yayo yekudzora tekinoroji mumuchina chishandiso chekudyisa dhiraivha pakushandisa, kuitira kuti muchina wemuchina wekufambisa chimiro chave shanduko huru uye kuita kusvetuka kutsva mukuita kwemuchina.
TheMainAzvakanakiraLinearMotorFeedDrive:
Yakasiyana-siyana yekumhanya kwekudya: Inogona kubva pa1 (1) m / s kusvika kupfuura 20m / min, ikozvino machining centre nekukurumidza-mberi kumhanya yasvika 208m / min, nepo yechinyakare muchina chishandiso nekukurumidza-mberi kumhanya <60m / min. , kazhinji 20 ~ 30m / min.
Yakanaka yekumhanyisa maitiro:Kumhanya kutsauka kunogona kusvika (1) 0.01% kana pasi.
Yakakura kukwidziridza: Linear mota inokwirisa kukwirisa kusvika ku30g, ikozvino machining center feed acceleration yasvika 3.24g, laser processing machine feed acceleration yasvika 5g, ukuwo yechinyakare muchina chishandiso chekudya ichiwedzera mu1g kana zvishoma, kazhinji 0.3g.
High positioning accuracy : Kushandiswa kwe grating yakavharwa-loop control, positioning right kusvika 0.1 ~ 0.01 (1) mm. iko kushandiswa kwefeed-forward control ye linear motor drive system inogona kuderedza zvikanganiso zvekutevera nekanopfuura ka200. Nekuda kwemaitiro akanaka ekuchinja kwezvikamu zvinofamba uye mhinduro inonzwisisika, pamwe nekunatsiridza kwekutonga kwekududzira, nano-level control inogona kuwanikwa.
Kufamba hakuna kuganhurirwa : Iyo yechinyakare bhora screw drive inoganhurwa nekugadzirwa kwescrew, kazhinji 4 kusvika 6m, uye mamwe mastroke anoda kubatanidza iyo yakareba screw, zvese kubva mukugadzira uye mukuita hazvina kunaka. Iko kushandiswa kweiyo linear mota drive, iyo stator inogona kurebesa, uye maitiro ekugadzira ari nyore, kune yakakura-yekumhanya machining centre X-axis inosvika 40m kureba kana kupfuura.
Kufambira mberi kweLinearMotor uyeIts DriveControlTechnology:
Linear motors dzakafanana neyakajairwa mota mumusimboti, ndiko chete kuwedzera kwecylindrical pamusoro pemota, uye mhando dzayo dzakafanana nedzechinyakare mota, senge: DC linear motors, AC inogara magineti synchronous linear motors, AC induction asynchronous. linear motors, stepper linear motors, nezvimwe.
Semutsetse we servo mota inokwanisa kudzora kurongeka kwekufamba kwakaonekwa mukupera kwema1980, nekuvandudzwa kwezvinhu (sezvakaita magineti zvechigarire), zvishandiso zvemagetsi, tekinoroji yekudzora uye tekinoroji yekunzwa, kuita kwemutsara servo motors kunoramba kuchivandudza, mutengo uri kuderera, uchigadzira mamiriro ekushandisa kwavo kwakapararira.
Mumakore achangopfuura, iyo mutsara mota uye dhiraivha yekudzora tekinoroji inofambira mberi munzvimbo dzinotevera: (1) mashandiro anoramba achivandudza (sekusundidzira, kumhanya, kukurumidza, kugadzirisa, nezvimwe); (2) kuderedza vhoriyamu, kuderedza tembiricha; (3) kuwanda kwakasiyana-siyana kuzadzisa zvinodiwa zvemhando dzakasiyana dzematurusi emuchina; (4) kuderera kukuru kwemutengo; (5) nyore kuisa uye kudzivirira; (6) kuvimbika kwakanaka; (7) kusanganisira CNC masisitimu Muiyo inotsigira tekinoroji iri kuramba ichiwedzera kukwana; (8) yakakwirira yekutengeserana.
