Choose the correct processing method, the rational design of machining process. In addition to the156FM camshaft adjusting fork parts of the two process designing special fixture. Machine tool fixture of many kinds, among them, the most widely mon fixture, size specifications have been standardized, and a professional production plant. While widely used in batch production, designed for a certain workpiece processing services for the fixture, it needs each factory according to workpiece machining technology to design and manufacture. In this paper, fixture design are the main contents of design jig boring machine and milling fixture, the design ofa test fixture. Key Words: Adjust the fork , Processing technology, processing method, process documentation, 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 III 目录摘要........................................................................................................................
