摘要
本设计的内容可分为机械加工工艺规程设计和机床专用夹具设计两大部分。首先,通过分析B6065刨床推动架,了解到推动架在B6065刨床加工中的作用。运用机械制造技术及相关课程的一些知识,解决推动架在加工中的定位、加紧以及工艺路线的安排等方面的相关问题,确定相关的工艺尺寸及选择合适的机床和刀具,保证零件的加工质量。其次,依据推动架毛坯件和生产纲领的要求及各加工方案的比较,制定出切实可行的推动架加工工艺规程路线。最后,根据被加工零件的加工要求,参考机床夹具设计手册及相关方面的书籍,运用夹具设计的基本原理和方法,拟定夹具设计的方案,设计出高效、省力、经济合理并且能保证加工质量的夹具。
夹具设计的主要内容是铣床夹具和钻床夹具,分别加工Φ50和Φ35端面和Φ16孔。第一套夹具是通过利用一个大端面和一个定位销与一个挡销来完成定位,利用浮动压紧机构对零件进行夹紧;再配合两个定位块进行铣端面。有支承板与底面的平行度误差和中心孔轴线与底面的垂直度误差。第二套夹具是通过液压装置来进行夹紧,通过短心轴进行中心孔定位,定位方式与上一套类似。此夹具存在的误差与上一套夹具的误差情况相同。
关键词机械加工、工艺规程、专用夹具、推动架
ABSTRACT
The design of the content can be divided into a point of order processing machinery and machine tools designed for the two most fixture design. First of all, through the promotion of B6065-planer, that promote the B6065 planer-processing role. Use of machinery manufacturing technology and related programs of knowledge, promoting the solution-processing in the position to step up and the line of the arrangement, and so on related issues, establishing the process and choose a suitable size and machine tools, spare parts processing quality assurance . Secondly, the basis for promoting the rough-pieces and production and processing requirements of the Programme of the programme, to promote the development of a practical point of order-processing line. Finally, in accordance with the requirements of the processing parts processing, machine tool fixture design reference manual and related aspects of the books, use of fixture design of the basic principles and methods, the programme drawn up fixture design, design efficient, effort, economic and reasonable to ensure the quality of processing Fixture.
The main content of the fixture is milling fixture and drilling fixture, respectively processing Φ 50 and Φ35 face and Φ 16 hole the first set of fixture is through the use of a large end face and a positioning pin and a blocking pin plete the positioning, using
