?、軟_擊氣缸:這是一種新型元件。它把壓縮氣體的壓力能轉(zhuǎn)換為活塞高速(10~20米/秒)運動的動能,借以作功。沖擊氣缸增加了帶有噴口和泄流口的中蓋。中蓋和活塞把氣缸分成儲氣腔、頭腔和尾腔三室。它廣泛用于下料、沖孔、破碎和成型等多種作業(yè)。作往復(fù)擺動的氣缸稱擺動氣缸,由葉片將內(nèi)腔分隔為二,向兩腔交替供氣,輸出軸作擺動運動,擺動角小于 280°。此外,還有回轉(zhuǎn)氣缸、氣液阻尼缸和步進氣缸等。

SMC氣缸結(jié)構(gòu)
氣缸是由缸筒、端蓋、活塞、活塞桿和密封件組成,其內(nèi)部結(jié)構(gòu)如圖所示: SMC氣缸原理圖

根據(jù)工作所需力的大小來確定活塞桿上的推力和拉力。由此來選擇氣缸時應(yīng)使氣缸的輸出力稍有余量。若缸徑選小了,輸出力不夠,氣缸不能正常工作;但缸徑過大,不僅使設(shè)備笨重、成本高,同時耗氣量增大,造成能源浪費。在夾具設(shè)計時,應(yīng)盡量采用增力機構(gòu),以減少氣缸的尺寸。

SMC 氣缸所設(shè)緩沖裝置種類很多,上述只是其中之一,當(dāng)然也可以在氣動回路上采取措施,達到緩沖目的。 組合組合氣缸一般指氣缸與液壓缸相組合形成的氣-液阻尼缸、氣-液增壓缸等。*,通常氣缸采用的工作介質(zhì)是壓縮空氣,其特點是動作快,但速度不易控制,當(dāng)載荷變化較大時,容易產(chǎn)生“爬行”或“自走”現(xiàn)象;而液壓缸采用的工作介質(zhì)是通常認(rèn)為不可壓縮的液壓油,其特點是動作不如氣缸快,但速度易于控制,當(dāng)載荷變化較大時,采用措施得當(dāng),一般不會產(chǎn)生“爬行”和“自走”現(xiàn)象。把氣缸與液壓缸巧妙組合起來,取長補短,即成為氣動系統(tǒng)中普遍采用的氣-液阻尼缸。氣-液阻尼缸工作原理見圖42.2-5。實際是氣缸與液壓缸串聯(lián)而成,兩活塞固定在同一活塞桿上。液壓缸不用泵供油,只要充滿油即可,其進出口間裝有液壓單向閥、節(jié)流閥及補油杯。當(dāng)氣缸右端供氣時,氣缸克服載荷帶動液壓缸活塞向左運動(氣缸左端排氣),此時液壓缸左端排油,單向閥關(guān)閉,油只能通過節(jié)流閥流入液壓缸右腔及油杯內(nèi),這時若將節(jié)流閥閥口開大,則液壓缸左腔排油通暢,兩活塞運動速度就快,反之,若將節(jié)流閥閥口關(guān)小,液壓缸左腔排油受阻,兩活塞運動速度會減慢。這樣,調(diào)節(jié)節(jié)流閥開口大小,就能控制活塞的運動速度。可以看出,氣液阻尼缸的輸出力應(yīng)是氣缸中壓縮空氣產(chǎn)生的力(推力或拉力)與液壓缸中油的阻尼力之差。
