随着现代制造业的发展和对人才的需求,机床夹具的设计和选用成为每个技术工人都应具备的基本技能。如何让理论基础水平不高的中职学生掌握这项技能,成了机械专业教师经常讨论的问题。从夹具设计过程中定位基准的选择、定位方法、定位元件的选用、定位误差的分析计算、夹紧机构的选用等方面入手,提出了设计题目简单化、设计环节步骤化的概念,以适应中职教育。
With the development of modern manufacturing industry and the demand for qualified personnel, the design and selection of machine tool fixtures have become the basic skills that every skilled worker should have. How to make the theoretical basis of vocational students to master this skill has become a mechanical professional teachers often discuss the issue. From the aspects of the choice of positioning datum, the positioning method, the selection of positioning element, the analysis of positioning error and the selection of clamping mechanism in the process of fixture design, the concept of simple design and step-by-step design is put forward to adapt to Vocational education.
