摘　　要：针对中小型企业中的斜面斜孔类零件难以加工问题,利用发明问题解决理论(Theory of the Solution of Inventive Problems,TRIZ)的“功能定义—功能分类—功能整理”3步骤进行功能分析,从而找出中小企业中的专用机械式夹具功能不足的缺陷,再通过“问题描述—问题转换—方案生成—创新设计”步骤设计出一款基于三轴机床斜面斜孔加工夹具。该夹具扩大了三轴机床加工工艺范围,提高了加工工件的精度,缩短了加工的基本时间和辅助时间。本创新设计实现在经济上合理、理论上科学、实践上可行、转化上有效。In view of the difficulty in machining inclined hole parts in small and medium-sized enterprises, this paper analyzes the functions of the special mechanical fixture in small and medium-sized enterprises by using the three steps of “function definition-function classification-function arrangement” of Theory of the Solution of Inventive Problems(TRIZ) innovation theory,and then designs an inclined hole machining fixture based on three-axis machine tools through the steps of “problem descriptionproblem transformation-scheme generation-innovative design”. The fixture enlarges the processing range of three-axis machine tools, improves the precision of machining workpieces, and reduces the basic and auxiliary time of machining. This innovative design is economically reasonable, theoretically scientific, practically feasible and effectively transformed.
