Machine tool fixture design teaching showcase
The machine tool fixture design teaching showcase is a set of "machine tool fixture" display cabinets based on the syllabus edited by Cai Guangyao, Xue Yuanshun, Li Qingshou, etc. of the Ministry of Machinery Industry, mainly from the geometric relationship of each link of the mechanical processing technology system, to clarify the fixture to ensure processing accuracy It introduces the principle of fixtures, introduces the knowledge of fixture components, and discusses the development direction of machine tool fixtures. Among them, it provides a comprehensive introduction to universal adjustable and group fixtures, combined fixtures, automated fixtures, etc. It is an ideal mechanical display cabinet for each mechanical specialty of the school.
