摘要
本文介绍了零件的加工过程中定位、装夹、加紧、钻模以及加工方面、夹具设计上的相关知识。综述了国内外目前XX的制造技术及发展趋势。通过对XX的使用性能、工作条件、结构、技术要求的了解,对斜齿轮的加工工艺规程进行研究改进,提出了在加工过程中常出现的问题及改进的办法,使斜齿轮的精度和表面质量得到很大提高,降低了废品率,提高了劳动生产率。并绘制夹具的二维CAD图形。与在对国内外夹具的设计现状进行分析的基础上,针对中小企业广泛使用夹具常出现的情况,我们有必要对夹具进行设计,具有现代机床夹具设计的相关知识,这样可有效地提高夹具设计的速度和质量,从而提高企业效益。
abstract
This paper introduces the knowledge of positioning, clamping, tightening, drilling, machining and fixture design in the process of parts processing. The manufacturing technology and development trend of XX at home and abroad are reviewed. Through the understanding of the performance, working conditions, structure and technical requirements of XX, the processing regulations of the helical gear are studied and improved. The problems and the improved methods are proposed in the process of processing. The accuracy and surface quality of the helical gear are greatly improved, the rate of waste products is reduced and the labor productivity has been improved. . And draw the two-dimensional CAD graphics of the fixture. On the basis of analyzing the current situation of fixture design at home and abroad, in view of the frequent use of jig in small and medium-sized enterprises, it is necessary for us to design the fixture and have the relevant knowledge of modern machine tool fixture design so that the speed and quality of fixture design can be improved effectively so as to improve the efficiency of the enterprise.

机械加工工艺概述
机械加工工艺是指用机械加工的方法改变毛坯的形状、尺寸、相对位置和性质使其成为合格零件的全过程,加工工艺是工人进行加工的一个依据。
机械加工工艺流程是工件或者零件制造加工的步骤,采用机械加工的方法,直接改变毛坯的形状、尺寸和表面质量等,使其成为零件的过程称为机械加工工艺过程。比如一个普通零件的加工工艺流程是粗加工-精加工-装配-检验-包装,就是个加工的笼统的流程。
机械加工工艺就是在流程的基础上,改变生产对象的形状、尺寸、相对位置和性质等,使其成为成品或半成品,是每个步骤,每个流程的详细说明,比如,上面说的,粗加工可能包括毛坯制造,打磨等等,精加工可能分为车,钳工,铣床,等等,每个步骤就要有详细的数据了,比如粗糙度要
