2、量,需设计专用夹具,以满足加工过程的需要,从而加工出合格的产品。关键词: 汽车变速箱体;工艺规程;夹具Abstract: Transmission case is a key part in the drive system of the vertical lift platform mill machine. So its machining quality may have direct effect on performance and longevity of service. This pap
3、er aims at enhancing the machining efficiency of transmission case. So at first, we need to take analysis of the structure and techniques of the transmission case, and then find out a reasonable precept, which should be simple, operate conveniently and ma
4、ke sure the machining quality. At last, we carry through machining according to the decided precept and right procedure to meet the design demand. Besides that, for the sake of enhancing work productivity, reducing the work force and making certain the qu
5、ality, we need to design special clamp.Therefore, special procedure was choosed to be designed to meet the machining demand.Keywords : transmission case;techniquesregulations;clamp第7页本科毕业论文(设计)目录绪论………………………………………………………………………………3第一章.工艺分析1.1工艺方案制定…………………………
