Pneumatic actuator -Pneumatic silinda
Mitundu ya masilinda
1.1 Maphunziro a Line Line
Masilinda okhazikika, masilinda opyapyala, zolembera-zobowola
Clamping cylinder: Ndi loko, zotsekera mpweya-zotsekera, ndi zoteteza-zoletsa mpweya-zozimitsa mpweya.
Kuyika kwa silinda: Silinda payokha sagwirizana ndi-kuyika mapointi kapena double stroke
Pawiri-axis cylinder: Mphamvu yotulutsa kawiri, yotha kupirira nthawi zina zopindika.
Kulondola kwa malo kwa silinda kumadalira malire. Mukamagwiritsa ntchito ndi mphamvu yayikulu yotulutsa kapena kuthamanga kwambiri, malire ayenera kuwonjezeredwa. Chifukwa chake ndikuletsa pisitoni kuti isakhudze kwambiri ndikuwononga mosavuta mutu wa silinda. Ma pistoni ang'onoang'ono, -masilinda afupiafupi, amadalira zitsulo zawo zolimba
Kapangidwe ka kalozera: Single-masilinda oyenda nawo nthawi zambiri sayenera kupakidwa mwachindunji ndipo amayenera kukhala ndi kalozera/katundu{1}}zonyamula (ma shaft, mizere, milozera). Ma pistoni ang'onoang'ono, masilinda afupiafupi-a sitiroko, osanyamula katundu wamkulu, komanso opanda zolozera/zonyamula{4}}zovomerezekanso. Matatu-axis cylinder ali ndi mawonekedwe a ndodo
Zoletsa-zodzizungulira{1}}zigawo: Zopingasa{2}}zosakhazikika, zokhala ndi ndodo
1.2 Mtundu wa Rotary: Silinda ya Rotary
1.3 Magawo ogwira ntchito: Masilinda a Gripper /, masilinda otsekera
2. Theoretical linanena bungwe mphamvu ya silinda
Kukambitsirana (N) kwa silinda wamba-ndi: Fa=0.25π*D^2*P
Mu formula:
Kutalika kwa silinda (mm
Mphamvu yogwira ntchito (MPa) ya silinda p.
Theoretical tensile force (N) ndi: Fa=0.25π*(D-d)^2*P
M'njirayi, pamene d ndi m'mimba mwake wa pisitoni ndodo (mm), akhoza kuyerekezedwa kuti d=0.3D.
3. Kulemera kwa silinda
Kuchuluka kwa katundu wa silinda: Zimatanthawuza chiŵerengero cha mphamvu yeniyeni yolemetsa F ya silinda ndi mphamvu yotulutsa mphamvu F0.
Kulemera kwa katundu ndi chinthu chofunikira posankha silinda. Mphamvu zenizeni zomwe zimagwira pa pistoni shaft zimasiyanasiyana ndi katundu wosiyanasiyana.
Katundu weniweni wa silinda amatsimikiziridwa ndi momwe ntchito zikuyendera. Ngati kuchuluka kwa katundu η kutsimikiziridwa, kutulutsa kwamalingaliro kwa silinda kungadziwikenso. Kusankhidwa kwa mlingo wa katundu η kumagwirizana ndi ntchito ya katundu wa silinda ndi liwiro la kuyenda kwa silinda.
4. Kuwerengera kwa mphamvu yotulutsa ndi kugwiritsa ntchito mpweya wa silinda
Kuwerengera kutulutsa kwamphamvu kwa silinda. Kutenga -ndodo iwiri-yomwe ikuwonetsedwa mu Chithunzi 10-14 mwachitsanzo, kukankhira F1 kopangidwa ndi pisitoni ndodo pamene pisitoni ikupita kumanja ndi mphamvu yokoka F2 yopangidwa ndi pisitoni ndodo ikamasunthira kumanzere ikhoza kuwerengedwa molingana ndi ma equations (10-2) (10-2) (10-2) (10-2)
(2) Kugwiritsa ntchito mpweya q kwa mpweya woponderezedwa kwa silinda imodzi yobwerezabwereza ya silinda kumatha kuwerengedwa ndi equation (10-4) :
Popeza mphamvu yogwira ntchito yofunikira pa chipangizo chilichonse cha pneumatic ndi yosiyana, payenera kukhala mulingo wogwirizana wowerengera momwe mpweya umayendera. Nthawi zambiri, kuthamanga kwa mpweya woponderezedwa pamakanikizidwe osiyanasiyana kumasinthidwa kukhala kutulutsa kwaulele kwa mpweya pamlingo wokhazikika wa mumlengalenga wowerengera, ndiko kuti:
Q=q× (p+0.103) /0.103
Munjirayi: Q - kugwiritsa ntchito mpweya kwaulere (m³/s) p - Kuthamanga kwa mpweya woponderezedwa (Mpa)
5. Kusankhidwa kwa silinda
Malinga ndi zofunikira za ntchito ndi zikhalidwe, sankhani molondola mtundu wa silinda.
Ngati palibe chochititsa chidwi kapena phokoso lamphamvu pamene silinda ikufika kumapeto kwa sitiroko, silinda ya buffer iyenera kusankhidwa. Ngati pakufunika kulemera kopepuka, -silinda yopepuka iyenera kusankhidwa. Ngati malo oyikapo ndi opapatiza ndipo sitiroko ndi yaifupi, silinda yopyapyala imatha kusankhidwa. Pali katundu wozungulira, ndipo silinda yokhala ndi ndodo yowongolera ndiyosasankha. Kulondola kwa braking kumafunika, ndipo silinda yotsekera iyenera kusankhidwa. Ndodo ya pistoni siyiloledwa kuzungulira. Silinda yokhala-yopanda ndodo yozungulira ikhoza kusankhidwa. Ma silinda osagwira kutentha akuyenera kusankhidwa{10}}malo otentha kwambiri. M'malo ochita dzimbiri, ma silinda osachita dzimbiri{12}ayenera kusankhidwa. M'malo ovuta okhala ndi fumbi, zophimba zafumbi ziyenera kuyikidwa kumapeto kwa ndodo ya pistoni. Zikapanda kuipitsidwa{{15}zopanda kuipitsidwa, mafuta{16}aulere kapena amafuta{17}}masilinda opanda mafuta, ndi zina zotero, ayenera kusankhidwa. Kuchuluka kwa silinda yosankhidwa kumatsimikiziridwa potengera katundu wofunikira, kuthamanga kwa mpweya komwe kumagwiritsidwa ntchito komanso momwe amachitira
Sankhani silinda ya silinda ndi mtunda woyenda wa workpiece:
Zimakhudzana ndi nthawi yogwiritsira ntchito komanso kugunda kwa makina, koma kawirikawiri, sitiroko yonse siyenera kusankhidwa kuti pisitoni isagwirizane ndi mutu wa silinda. Ngati ikugwiritsidwa ntchito pazitsulo zokhotakhota, ndi zina zotero, ndalama zowonjezera za 10 mpaka 20 mm ziyenera kuwonjezeredwa malinga ndi stroko yowerengedwa.
Sankhani mndandanda wa silinda
Sankhani mtundu wa kukhazikitsa silinda
Mitundu yosiyanasiyana ili ndi njira zosiyanasiyana zoikira, makamaka mtundu woyambira, mtundu wa phazi, mtundu wa flange, U-mbeu yooneka ngati shaft, ndi mtundu wa khutu la shaft
Sankhani zotchingira: palibe chotchinga, chotchinga mphira, chotchingira mpweya, ndi chotsekereza cha hydraulic shock
Chosinthira maginito chosankhidwa chimagwiritsidwa ntchito makamaka pozindikira malo, ndipo pamafunika kuti mphete ya maginito imangidwe mu silinda.
Zigawo zosankhidwa za silinda zimakhala ndi zolumikizira zoyenera
6. Mitundu yosankhidwa yodziwika bwino ya masilindala: Airtac ndi SMC
