2、液壓回路的工作情況。選擇合理的液壓元件,完成整個(gè)液壓回路的組裝。再者,夾持器的設(shè)計(jì)類型為常閉型夾持器,其結(jié)構(gòu)分布均勻,依靠碟簧和增力缸夾緊,用液壓松開,能夠夾持為73mm與63mm的鉆桿。主要用于煤炭工程類全液壓動(dòng)力頭式鉆機(jī)裝卸鉆桿,其結(jié)構(gòu)簡單、操作便利、有良好的市場推廣效益。本設(shè)計(jì)要求設(shè)計(jì)出合理的夾持器結(jié)構(gòu),盡量使整個(gè)夾持器的體積小,計(jì)算好碟簧與夾持器液壓缸所能提供的夾持力,算出夾持器各零部件的大小尺寸,對整個(gè)夾持器的結(jié)構(gòu)進(jìn)行有限元受力分析,找出不合理的結(jié)構(gòu)部位并加以改進(jìn)。關(guān)鍵詞:夾持器設(shè)計(jì);液壓系統(tǒng)設(shè)計(jì);有限元分
