【正文】 o the technical requirements of accurate positioning and tight clamping technology device, it is mainly used to ensure the product processing quality, reduce labor intensity auxiliary products detection, display, transportation etc.. Therefore, how to design the fixture has bee an important task of mechanical manufacturing. Machine tool fixture fixture in a, be fixed to the machine, can be processing tool and the tool to maintain the correct relative position, and to overe the effect of the cutting force, smooth processing. Machine tool fixture for universal jig and fixture two. This paper, mainly on the general vertical milling machine slot parts of the special fixture for research, analysis. Key words：The process；worker one；orient the scheme； Special fixture； vertical milling machine；目錄1目錄第一章 緒論
