飞轮的加工工艺及钻4×Φ20孔的夹具设计
摘要
在经济飞速向前的当下，制造业快速发展的今天。非标零件的尺寸、结构也千变万化。以往设计的通用夹具，越来越多的面临淘汰。所以专用夹具的设计与生产越来越广泛。专用夹具的研究其主要内容有定位方案、夹紧方案的确定，定位元件、夹紧元件的选择，导向装置的选择等等。
本次设计研究的对象是飞轮。设计内容包括2个方面：1、工艺分析；2、钻4XФ20孔钻床专用夹具设计。飞轮是机器上不可或缺的零件之一，为机器及零部件的正常运转提供保障。
从零件结构分析入手，合理选择定位基准，各种刀具参数选择以及切削用量的选择等。在安排工艺过程时，根据加工要求不同，需要进行粗精加工。另外还确定了切削参数，加工工时，填写工艺过程卡片和工序卡片。专用夹具设计内容有：确定定位方案及元件，确定夹紧方案及元件，确定导向装置，计算切削力及夹紧力等。
关键词：飞轮、工艺、4XФ20孔、钻床、专用夹具
Abstract
With the rapid development of the economy, the rapid development of the manufacturing industry is today. The size and structure of the non- standard parts are alsovaried. More and more general jig designed in the past are facing elimination. So the design and production of special fixture are becoming more and more extensive. The main contents of the special fixture include the positioning scheme, the determination of the clamping scheme, the selection of the positioning element, the clamping element, the selection of the guiding device and so on.
The object of this design study is the flywheel. The design includes 2 aspects: 1, process analysis; 2, 4Xwith 20 drill hole drilling machine fixture design. The flywheel is one of the indispensable parts on the machine, providing guarantee for the normal operation of the machine and parts.
Starting from the analysis of the structure of the parts, the positioning datum, the selection ofvarious tool parameters and the selection of the cutting amount are selected reasonably. When the process is arranged, the rough finishing is required according to the different processing requirements. In addition, the cutting parameters, the processing time, the process card and the process card are filled in. The special fixture is designed to determine the positioning scheme and components, to determine the clamping scheme and components, to determine the guiding device, to calculate the cutting force and the clamping force.
Keywords: special fixture, flywheel technology, 4Xwith 20 hole drilling
