法兰盘斜孔和径向孔加工卧、斜轴回转分度钻床夹具设计

摘要

本课题是法兰盘卧、斜轴回转分度钻床夹具设计，许多功能完全相同而结构工艺性不同的零件，它们的加工方法与制造成本有着很大的差别，应仔细审查零件的结构工艺性，定位基准选择、加工方法选择。根据零件主要表面的技术要求、生产类型、材料的性能、零件的结构、形状尺寸、毛坯尺寸、毛坯情况、生产计划安排及现有的对比，确定其最佳夹具加工方案。

本设计中，根据法兰盘尺寸公差、形状和位置公差、表面粗糙度、技术要求、工件材料、等要求来设计夹具过程。根据给定的生产量大小来确定夹具类型过程。根据现有生产条件，充分发挥现场技术条件手段和技术力量的潜力来设计夹具过程。机床夹具的总体设计包括从方案制定到总装配图的设计的全部过程。包括确定工件的定位，选择或设计定位元件，计算定位误差；确定刀具的导引和对刀方式，选取或色痕迹导引元件或对刀元件；确定工件的夹紧方式，选择或设计夹紧机构或装置，计算夹紧力；确定夹具体及其他装置的结构类型等。

通过合理的设计，在保证零件加工质量前提下,提高生产效率,降低消耗,以取得较好的经济效益和社会效益。

Abstract

The topic is Plectrum Technology Analysis and fixture design,.Many functionally identical nature and structure of different parts, their processing methods and the cost of manufacturing is very different, we should carefully examine parts of the structure, positioning baseline options, the processing method of choice. According to the major surface parts to the technical requirements, product type, material properties, components, the structure, shape and size, the rough size, Blank, production plans and the current contrast, we found that the best processing program.

The design, based on tolerance Plectrum size, shape and position tolerances, surface roughness, technical requirements, workpiece material, rough type, heat treatment and surface protection requirements of the design process. According to the output size to determine the process. According to the unit's first production conditions, and give full play to the scene technical means and technologies for the potential of the design process. Its object processing process analysis of the technology components of the structure analysis to determine the type of production and forms of organization. Blank design process to determine line, positioning benchmark choice. The fixture design, including programming from the general assembly to the design of the entire process. Including the identification of the workpiece positioning, choice or design positioning components, calculated positioning error; Tool to determine the right guidance and knives, Color selection or guidance components or traces of knife components; determine the workpiece clamping, choice or design or clamping devices, Clamping calculation; identify specific folder and other devices, and other types of structures.

Through rational design, quality assurance parts processing premise, improve production efficiency and reduce consumption, in order to obtain a better economic and social benefits.

Keyworks: Fixture,Flange, Rotary-Pisition.
