第第23頁共23頁啟動電機，通過傳送帶傳動渦輪蝸桿帶動凸輪轉動，凸輪推動推桿運動。當凸輪從最低點運動到最高點作推程運動時，推桿推送物品作上升運動，同時壓縮彈簧。凸輪從最高點作回程運動時，推桿在自身重力和彈簧彈力的作用下作下降運動。電動機不斷地提供電能帶動整個裝置的傳動，完成構件上下往復運動，把一個物品從一個位置推送到另一個位置。五總結與建議本次大作業不同于前兩次，這次是綜合設計，并不像之前的只是設計單個構件，這次所需要設計的東西更多，需要各個構件之間的配合才能達到設計的要求。這次作業還是有一定難度的，它需要對學過的東西十分熟練，并且還需要對沒有學過的東西進行自學從而完成設計任務。在實際過程中我使用了CAD、C語言編程、EXCEL繪圖等軟件，并且查閱了關于物塊推送的相關資料，知道了物塊推送需要較高的效率、穩定性、精確度，當然還需要環保，即噪音小，動力使用效率高，不產生太多廢棄物。通過本次大作業我學會了很多。首先是在設計方面，我學會了綜合考慮，對比選擇最優機構，學會了發現問題并及時解決問題，當然我也學會了多種查閱資料的方法，比如圖書館的相關文獻、googel文獻引索、中知網。團隊精神也是很重要的，在這次設計中，我們小組三人分工明確，積極探討，深深體會到了團隊的作用。當然也發現了自身的很多不足，所以決定在假期里來填補自己的不足，以便今后完成更多，更復雜的設計，為自己的專業服務。像這種能夠鍛煉自己的機會并不多，我建議在日后的學習中可以多一些這樣的機會，讓我們更牢固的掌握我們所學到的專業知識。參考文獻《機械原理》高等教育出版孫恒主編《C語言教程》清華大學出版社譚浩強主編《機械原理課程設計實習指南》機電學院郭紅利主編附錄：推桿運動學數據：角度位移速度加速度00070.03320250.2666676.1115570.033202101.06666712.223170.033202152.418.33464970.033202204.26666724.44619970.033202256.66666730.55774970.033202309.636.66929970.0332023513.06666742.78084970.0332024017.06666748.89239970.0332024521.655.00394870.0332025026.66666761.11549870.0332025532.26666767.22704870.0332026038.473.33859870.0332026545.06666779.45014870.0332027052.26666785.56169770.033202756091.67324770.0332028067.73333385.561697-70.033202
