换挡叉零件的机械加工工艺过程及工艺装备设计.doc

摘　要 制造商不断推出各种各样先进的汽车零部件制造技术,拨叉裂解技术就是20世纪90年代出现的一种先进的拨叉加工新技术,和传统加工技术相比,该技术具有大幅度提高产品质量、提高生产率、降低生产成本等突出优点而备受业界关注。我们国家正在不断地改变拨叉的传统加工方法，加快提高拨叉的加工水平，不断缩小同先进汽车生产国家的差距，例如一汽，二汽，上汽，奇瑞等生产厂与世界先进拨叉生产水平的差距越来越小，不断加强了我国汽车整体的生产水平。 机械制造工艺学课程设计使我们学完了大学的全部基础课、技术基础课以及大部分专业课之后进行的.这是我们在进行毕业设计之前对所学各课程的一次深入的综合性的总复习,也是一次理论联系实际的训练,因此,它在我们四年的大学生活中占有重要的地位。 就我个人而言，我希望能通过这次课程设计对自己未来将从事的工作进行一次适应性训练，从中锻炼自己分析问题、解决问题的能力，为今后参加祖国的“四化”建设打下一个良好的基础。 Abstract The manufactory continuously releases the forerunners car of various each kind zero parts manufacturing technique, stir the fork crack solution technique is the stir of a kind of forerunner fork which appears in 90s for 20 centuries to process a new technique, compared with the traditional processing technology, that technique have significant exaltation product quality, raise rate of production and lower production cost etc. We are just national at constantly the change stir fork of tradition process a method, speed an exaltation to stir process of fork level, continuously contract a together advanced car to produce a national margin, for example one vapor, two vapors, up the vapor, strange Rui etc. produce factory and world forerunner stir fork production the margin of the level more and more small, continuously strengthened our country the car whole production level. The machine manufacturing craft learns a course design to make us to carry on after finishing learns all foundation lessons, lesson and greatly part of professional lessons of the technique foundation of university. This is that we are before carry on graduation design to once go deep into of each course learn of synthetic always review, is also an ories to contact actual training, therefore, it occupies an important position in we the university of four years the life. I am personal but speech, I hope to pass this course design to oneself will carry on the work for be engaged in an adaptability training in the future, toughen oneself to analyze a problem, problem-solving ability
