C6150车床主轴箱箱体加工工艺及工装夹具设计

摘要

箱体是对零部件有包容，支撑的作用，让它们保持一定的相应位子，而得到正常的运动关系和定量的精度，它还为它里面的零件起到了很好的润滑条件，进而，它具备安全保护和密封的作用并带有有一定的隔绝震动的作用，起到保护内部零件不受到外部损害的作用。所以在日常的生活学习工作中应用得十分广泛，也起到十分重要的作用。这次设计能让我们很熟练使用机械制造工艺学这门课程中的基本理论以及在生产实习中学到的实践知识，能正确地解决一个零件在加工中的定位，夹紧以及工艺路线的安排，工艺尺寸确定等一系列的问题，保证零件的加工质量的确定。另外一方面毕业设计是在教学程序中一个不能缺少的实践性很强的十分重要的一环。它的目的在于培养学生能够正确的拥有机械设计能力。一般按照零部件图条件以及要求，需要完成零部件的加工工艺规程设计，让制造方向的学生能够熟练的掌握所学课本上的专业知识，培养学生提高动手的能力，能够达到活学活用的境地。

ABSTRACT

Box the body rise to accept to zero partses, prop up of function, make them keep certain opposite seat to get the normal sport relation and enough accuracy, he returned to rise a better lubrication condition for the spare parts of its inner part in the meantime, in the meantime, he still has a safe protection and seal completely of the function have a function of separate the earthquake certainly, rise to protect the effect that the internal spare parts is free from to the exterior to violate.So make use of very extensively in the daily living work, also have count for much of of function.This design can let us make use of the machine manufacturing craft to learn the basic theories in the course masterly and Be producing the fulfillment knowledge that the practice high school arrive, resolve a spare parts with accuracy in the middle of process of fixed position, clip tightly and the craft route arrangement, the craft size assurance etc. problem, promise the spare parts processes quality.Graduating a design on the other hand is a fulfillment of essential to have the very strong important link is in the teaching link.The purpose lies in training student's first step to set up right of design an ability to the plete zero partses to process the craft rules distance design according to zero parts diagram and condition and the request, make the studentof the manufacturing direction be able to integrate to control the professional knowledge study, raise a student to begin anability,attain to live to learn to liveto use.
