支架的铣宽5槽专用夹具设计及加工工艺装备含5张CAD图+说明书

支架——A2

摘要
零件加工工艺规程在零件生产过程中非常重要，指导操作者按要求加工尺寸保证公差等。专用夹具是针对某一道工序设计的机床夹具，保证产品的生产效率和生产质量。因此，对另加加工工艺规程和专用夹具进行设计，在零件加工过程中非常重要，对其进行研究也非常有意义。
本次设计选取支架零件为被加工件，主要任务有加工工艺规程以及专用夹具设计。加工工艺规程设计前分析了零件的材质，结构以及加工要求等。确定了生产和制造方式，设计了加工工艺路线，计算切削用量，填写工序卡等。本次专用夹具设计铣5槽，适用机床卧式铣床X62，铣刀为三面刃铣刀。对其定位和夹紧方案进行设计，选择定位和夹紧元件等。最后，完成CAD图形绘制及说明书的撰写等。

Abstract
Parts processing technology regulations arevery important in the production process of parts, guiding operators to ensure tolerance according to the required processing size. The special fixture is a machine tool fixture designed for a certain process to ensure the production efficiency and quality of products. Therefore, the design of additional processing procedures and special fixtures isvery important in the process of parts processing, and the research on them is alsovery meaningful.
This design chooses the bracket parts as the processed parts. The main tasks are the processing technology regulations and the design of special fixture. The material, structure and processing requirements of the partswere analyzed before the design of the processing procedure. The production and manufacturing methods are determined, the processing route is designed, the cutting parameters are calculated, and the process cards are filled in. This special fixture design milling 5 slots, suitable for machine tool horizontal milling machine X62, milling cutter for three-sided edge milling cutter. The positioning and clamping scheme is designed, and the positioning and clamping elements are selected. Finally, the drawing of CAD graphics and thewriting of instructions are completed.
Keywords: bracket; processing technology; special fixture; milling 5 slots; cutting parameters
