在中职机械专业《普通车工》课程教学中,高速车削三角螺纹是一个重要课题,它是中职生是否达到车工初级技术水平的重要考核标准之一,也是中职生学习后续螺纹加工的技术铺垫。但是,在车削三角形外螺纹的教学实践中,学生加工螺纹零件出现的螺纹牙型变形问题却是长期困扰一线教学工作者的难题。本文主要探讨如何利用提闭开合螺母法加工三角形螺纹的技能技巧,对车削三角形外螺纹教学工作具有一定的借鉴意义。
In the mechanics of vocational mechanics “ordinary lathe” course teaching, high-speed turning triangle thread is an important issue, it is whether vocational students reached the primary technical level car one of the important assessment criteria, but also secondary vocational students to learn the follow-up thread processing technology bedding. However, in the teaching practice of turning triangular external thread, the problem of the deformation of the thread form that the students process the threaded parts has long been troublesome front-line teaching workers. This article mainly discusses how to make use of the method of opening and closing the nut to process the triangle thread skill skill, which has certain reference significance to the turning triangle external thread teaching work.
