廻转盘加工工艺和工装规程设计
摘要:本次设计是对廻转盘加工工艺工装的规程设计,首先要明白机械加工工艺过程就是用切削的方法改变毛坯的形状、尺寸和材料的物理机械性质,使其成为具有所需要的一定精度、粗糙度等的零件。为了能具体确切的说明过程,使工件能按照零件图的技术要求加工出来,就得制定复杂的机械加工工艺规程来作为生产的指导性技术文件,学习研究制定机械加工工艺规程的意义与作用就是本课题研究目的。在整个设计过程中,我们将学习到更多的知识。
我们必须仔细了解零件结构,从工艺上认真分析零件图,培养我们独立识图的能力,增强我们对零件图的认识和了解。通过对零件图的绘制,能增强我们的绘图能力和运用AutoCAD软件的能力。
制订工艺规程、确定加工余量、工艺尺寸的计算,在整个设计中也是非常重要的,通过这些设计,不仅让我们更为全面地了解零件的加工过程、加工尺寸的确定,而且让我们知道工艺路线和加工余量的确定,必须与工厂实际的机床相适应。
对夹具的设计:我们必须要了解夹具的作用,然后根据定位、夹紧、对刀等方面进行总体的设计。这是对以前学习过的知识的复习,也是以后工作的一个铺垫。

The Design Of Hui Rotary Processing And Tooling Procedures
Abstract: This design is a point of order hui rotary tooling design process, We must first understand the machining process is to use the method by cutting to change the shape, size, and physical and mechanical properties of the material of rough into the partswith a required accuracy and roughness. In order to detail the process, make thework piece in accordancewith the technical requirements of parts processing, We need to develop a complex machining procedures as the guiding technical document production. Study and research the meaning and effect of this order of to development machining processes the purpose of this research project. During the process of Graduation Design,wewill learn more knowledge.
We must understand the parts of the structure carefully and according to the process to analyze the figure of Parts carefully, Develop our ability to independently identify map and enhance our knowledge and understanding of Parts. Through the mapping of parts that can enhance our capabilities and the use of AutoCAD drawing software.
Developed process of order, determine the allowances and the calculation of process dimensions, this is alsovery important in the entire design process. Through these designs, not only allows us to understand the machining process and determine the size more comprehensive, but also let us to know that the route of process and the determine of allowance must be adapted to the actual machine in factory.
The design of the fixture: We need to know the role of the fixture, Then according to the positioning, the clamping, tool and other areas to the overall design, This is the review of knowledge previously learned, but also a foreshadowing for futurework.
Keywords: Hui rotary Technology and equipment Processing Fixture
