2、工量的15%內(nèi)部20%。對(duì)工件進(jìn)行機(jī)械加工時(shí)，為了保證加工要求，首先要使工件相對(duì)于機(jī)床有正確的 位置，并使這個(gè)位置在加工過程中不因外力的影響而變動(dòng)。為此，在進(jìn)行機(jī)械加工前, 先要將工件裝夾好。用夾具裝夾工件時(shí)，工件相對(duì)于道具及機(jī)床的位置精度由夾具保 證，不受工人技術(shù)水平的影響，使一批工件的加工極度趨于一致，穩(wěn)定的保證工件的 加工精度。同時(shí)使用夾具裝夾工件方便、快捷，工件不需要?jiǎng)澗€找正，可顯著的減少 輔助工時(shí)，提高勞動(dòng)生產(chǎn)率；工件在夾具中裝夾后提高了工件的剛性，因此可加大切 屑用量，提高勞動(dòng)生產(chǎn)率；可使用多件、多工位裝夾工件的夾具，并可采用高效夾緊 機(jī)構(gòu)，進(jìn)一步提高勞動(dòng)生產(chǎn)率。在批量生產(chǎn)中使用夾

3、具后，由于勞動(dòng)生產(chǎn)率的提高、 使用技術(shù)等級(jí)較低的工人以及廢品率下降等原因，明顯得降低了生產(chǎn)成本。夾具制造 成本分?jǐn)傇谝慌ぜ?。每個(gè)工件增加的成本時(shí)極少的，遠(yuǎn)遠(yuǎn)小于由于提高勞動(dòng)生產(chǎn) 率而降低的成本。工件批量愈大，使用夾具所取得的經(jīng)濟(jì)效益就愈顯著。關(guān)鍵詞：泵體類零件，夾具,ABSTRACTA part of the container kind is the basic matter of a machine and a part.
