摘 要
機械制造技術基礎課程設計是我們在學完了大學的全部基礎課、專業(yè)基礎課以及專業(yè)課后進行的。這是我們在進行畢業(yè)設計之前對所學的各科課程一次深入的綜合性總復習，也是一次理論聯系實際的訓練。因此，他在我們的大學四年生活中占有重要的地位。
我這次設計的是撥叉831003，有零件圖、毛坯圖、夾具裝配圖、夾具零件圖各一張，機械加工工藝過程卡片和與所設計夾具對應那道工序的工序卡片各一張。首先我們要熟悉零件，題目所給的零件是撥叉831003。了解了撥叉的作用，接下來根據零件的性質和零件圖上各端面的粗糙度確定毛坯的尺寸和機械加工余量。然后我們再根據定位基準先確定精基準，后確定粗基準，最后擬定撥叉的工藝路線圖，制定該工件的夾緊方案，畫出夾具裝配圖。
就我個人而言，我希望通過這次課程設計對自己未來將從事的工作進一步適應性的訓練，希望自己在設計中能鍛煉自己的分析問題、解決問題、查資料的能力 ，為以后的工作打下良好的基礎。
由于能力有限，設計尚有很多不足之處，希望各位老師給予指導。
Abstract
Machinofacture technology curriculum design is that we mimic all basic courses , technology basic course and major part having completed university being in progress after the specialized course. This is that we always review before the graduation practice being in progress to what be learned every thorough comprehensiveness of course,be also that a theory contacts actual training , it occupies important position therefore, in our university for four years life.
My design is Bocha 831,003, part map, rough map, fixture assembly, a fixture parts of the map. Machining process with the card and the corresponding fixture designed by the procedures of the process of a card. First of all, we must familiar with the parts, subject to the parts is Bocha 831,003. Bocha understanding of the role, followed in accordance with the nature of parts and components in the face of the map on the roughness of rough determine the size and mechanical Jiagongyuliang. According to another location and then we set the benchmark fine first base, established after the benchmark crude, Bocha finalizing the road map process, the enactment of the workpiece clamping programme, to draw fixture assembly.
For me personally, I hope that through the curriculum design of their future will be further engaged in the work of adaptive training, in the hope that their design can exercise their own analysis, problem solving, the ability to search information, the work laid for the future A good foundation.
Because of limited capacity, there are a lot of design deficiencies, I hope that teachers give guidance.
