Choose the correct methods for processing , manufacturing process design. In addition, processing of loom crank parts design process special fixture. This paper focuses on the loom crankshaft parts mainly in the V block and the support plate to locate, near the straight plate and spring clamp, keyway milling for 2V block interference and the cutter can not, so to reduce the V block height, fixture design tobe convenient, simple. Keywords: processing technology, processing methods, process, fixture 优秀机械毕业设计欢迎下载学习交流加 QQ 197216396 专业机械设计解君之忧 II 目录摘要······························································································ II ABSTRACT ··························································································· III 1绪论······························································································ 1 机械加工工艺概述······································································· 1 机械加工工艺流程······································································· 1 夹具概述··················································································· 2 机床夹具的功能·········································································· 2 机床夹具的发展趋势···································································· 3 机床夹具的现状·····················
