33、，分別帶動凸輪做轉動控制連桿對工件的定位和通過齒輪帶動齒條和動力頭做往復直線運動。另一路直接傳動到送料機構，控制的送料機構的進退。即該系統由電動機 驅動，通過變速傳動將電動機的轉速由 960r/min 降到主軸的 2r/min，與傳動軸相連的凸輪機構控制送料，定位夾緊和進刀等工藝動作。其中動力頭由凸輪機構通過齒輪傳動帶動齒 條上下平穩地運動，則動力頭可帶動鉆頭平穩地上下移動從而保證了較高的加工質量。進刀機構負責動力頭的升降，送料機構將被加工工件推入加工位置，并由定位機構使加工工件可靠固定。三個執行構件的運動形式為： 1.進刀機構動力頭做垂直的往復直線運動，下移到最低點后立刻上移。在下移之前有

34、一段休止時間，此段時間則用于送料和定位夾緊。其中動力頭的行程為15mm。 2.送料機構做水平的往復運動，工作行程是40mm。初始時，送料機構迅速地將被加工 工件送到指定加工位置，稍作停頓后立即返回，且其在工件的加工過程中保持休止。 3.定位夾緊機構在水平面內做近似垂直直線運動，在工件的加工過程中對工件起固定 的作用。其中夾緊裝置的垂直行程為20mm。 功能分解圖： 送料機構功能 原 變 送料、定位夾緊、 動 機 速 進刀依靠凸輪機構 輸 齒 定位夾緊機構功能 出 輪 動 機 協調工作 力 構 new measures to promot e work, the courage to tak e
