Pneumatic actuator -Pneumatic silinda
Mitundu ya Pneumatic Cylinders
1.1 Maphunziro a Line Line
Masilinda a Pneumatic okhazikika, masilinda opyapyala a Pneumatic, zolembera-zooneka ngati Pneumatic cylinders
Clamping Pneumatic cylinder: Ndi loko, kutsekereza mpweya-kutseka loko, ndi anti-kudula mpweya{2}}kuteteza chitetezo
Pneumatic cylinder positioning: Pneumatic cylinder payokha sagwirizana ndi-kuyika ma point kapena double stroke
Pawiri-axis Pneumatic cylinder: Mphamvu yotulutsa kawiri, yotha kupirira nthawi zina zopindika.
Kulondola kwa malo kwa silinda ya Pneumatic 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 ya Pneumatic. Ma pistoni ang'onoang'ono, -masilinda afupiafupi a Pneumatic, amadalira zitsulo zawo zolimba
Kapangidwe kawongoleredwe: Single-ma silinda apneumatic a axis nthawi zambiri sayenera kupakidwa mwachindunji ndipo amayenera kukhala ndi kalozera/katundu-zotengera zonyamulira (ma shaft, mizere mizere, milozera). Ma pistoni ang'onoang'ono, masilinda afupiafupi-a pneumatic, pamene sakunyamula katundu wamkulu, komanso opanda chitsogozo/katundu-zonyamulira, ndizovomerezekanso. atatu-axis Pneumatic cylinder ali ndi mawonekedwe a ndodo yolondolera
Zoletsa-zodzizungulira{1}}zigawo: Zopingasa{2}}zosakhazikika, zokhala ndi ndodo
1.2 Mtundu wa Rotary: Silinda ya Rotary Pneumatic
1.3 Magawo ogwira ntchito: Masilindala a Gripper Pneumatic / chala Pneumatic silinda, kutsekereza ma silinda a Pneumatic
2. Theoretical linanena bungwe mphamvu ya Pneumatic yamphamvu
Kukambitsirana (N) kwa silinda wamba-acting Pneumatic cylinder ndi: Fa=0.25π*D^2*P
Mu formula:
Pneumatic silinda awiri (mm
Kuthamanga kwa ntchito (MPa) kwa silinda ya Pneumatic.
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. Katundu wa silinda ya Pneumatic
Kuchuluka kwa katundu wa silinda ya Pneumatic: Zimatanthawuza chiŵerengero cha mphamvu yeniyeni yolemetsa F ya silinda ya Pneumatic kwa mphamvu yotulutsa mphamvu F0.
Kuchuluka kwa katundu ndi chinthu chofunikira posankha silinda ya Pneumatic. Mphamvu zenizeni zomwe zimagwira pa pistoni shaft zimasiyanasiyana ndi katundu wosiyanasiyana.
Katundu weniweni wa silinda ya Pneumatic imatsimikiziridwa ndi momwe amagwirira ntchito. Ngati kuchuluka kwa katundu η kutsimikiziridwa, kutulutsa kwamalingaliro kwa silinda ya Pneumatic kungadziwikenso. Kusankhidwa kwa mlingo wa katundu η kumagwirizana ndi ntchito ya katundu wa Pneumatic cylinder ndi liwiro la kuyenda kwa Pneumatic cylinder.
4. Kuwerengera kutulutsa mphamvu komanso kugwiritsa ntchito mpweya wa silinda ya Pneumatic
Kuwerengera kwa kutulutsa kwa silinda ya Pneumatic. Kutenga -ndodo iwiri-yochita Pneumatic cylinder yomwe ikuwonetsedwa mu Chithunzi 10-14 mwachitsanzo, kukakamiza F1 kopangidwa ndi ndodo ya pisitoni pamene pisitoni ikupita kumanja ndi mphamvu yokoka F2 yopangidwa ndi pisitoni ndodo ikasunthira kumanzere ikhoza kuwerengedwa molingana ndi 10:-2) (10:-2) (10:-2)
(2) Kugwiritsa ntchito mpweya q kwa mpweya woponderezedwa kwa sitiroko imodzi yobwerezabwereza ya silinda ya Pneumatic ikhoza 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 ya pneumatic
Malingana ndi zofunikira ndi ntchito, sankhani molondola mtundu wa Pneumatic cylinder.
Ngati palibe chodabwitsa kapena phokoso lamphamvu pomwe silinda ya Pneumatic ifika kumapeto kwa sitiroko, silinda ya Pneumatic iyenera kusankhidwa. Ngati pakufunika kulemera kopepuka, -ntchito yopepuka ya Pneumatic cylinder iyenera kusankhidwa. Ngati malo oyikapo ndi opapatiza ndipo sitiroko ndi yayifupi, silinda yopyapyala ya Pneumatic ikhoza kusankhidwa. Pali katundu wotsatira, ndipo silinda ya Pneumatic yokhala ndi ndodo yowongolera ndiyosasankha. Kulondola kwa braking kumafunika, ndipo silinda ya Pneumatic yotsekera iyenera kusankhidwa. Ndodo ya pistoni siyiloledwa kuzungulira. Silinda ya Pneumatic yokhala-yosazungulira ndodo ingasankhidwe. Kutentha-masilinda a Pneumatic osagwira akuyenera kusankhidwa{10}}malo otentha kwambiri. M'malo ochita dzimbiri, dzimbiri{12}}ziyenera kusankha masilinda a Pneumatic osachita dzimbiri. M'malo ovuta okhala ndi fumbi, zophimba zafumbi ziyenera kuyikidwa kumapeto kwa ndodo ya pistoni. Zikapanda kuipitsidwa{{15}zopanda kuipitsidwa, mafuta-aulere kapena amafuta{17}}masilinda opanda mafuta a Pneumatic, ndi zina zotero, ayenera kusankhidwa. Kutalika kwa silinda ya Pneumatic yosankhidwa kumatsimikiziridwa kutengera katundu woyenerera, kuthamanga kwa mpweya komwe kumagwiritsidwa ntchito, komanso komwe akugwirira ntchito.
Sankhani Pneumatic silinda sitiroko ndi workpiece mtunda woyenda:
Zimakhudzana ndi nthawi yogwiritsira ntchito komanso kugunda kwa makina, koma kawirikawiri, sitiroko yonse siyenera kusankhidwa kuti pisitoni isagwirizane ndi mutu wa Pneumatic cylinder. Ngati ikugwiritsidwa ntchito pazitsulo zokhotakhota, ndi zina zotero, ndalama zowonjezera za 10 mpaka 20 mm ziyenera kuwonjezeredwa malinga ndi stroko yowerengedwa.
Sankhani mndandanda wa Pneumatic cylinder
Sankhani mtundu wa kukhazikitsa silinda ya Pneumatic
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 yamaginito imangidwe mu silinda ya Pneumatic.
Magawo osankhidwa a Pneumatic cylinder amaphatikizanso zolumikizira zoyenera
6. Mitundu yosankhidwa kawirikawiri ya Pneumatic cylinders: Airtac ndi SMC
