The industry sewing machine profession has already drawn up the line mark pattern standard，realizes each kind of line mark industry sewing machine basic organization type to pass through the long-term use quite to be mature, the organization type tends to the stereotypia. Product quality improvement, the variety development, the technical level enhance, the renewal then more performance continue the unceasing improvement in the original product foundation. Integration of machinery technology application, For the product gradation, the continuous transformation, the innovation provides a bigger space, but also must take the original product as the foundation, the increase automation, integrated or the systematized function. Types of sewing machine head material selection and processing tool for analyses confirm that with AutoCAD draw out key parts processing, and fixture design of the reliability, feasibility, finally design process, according to the origin of the process chosen coordinates, with FANUC system the process were numerical control programming. Finally, the parts will be processed and assembled, and then the feasibility of the process is determined. Keywords: Sewing machine ; Key parts; Fixture design; Programming design 摘 要 I Abstract II 目 录 III 第一章 绪论 1 1.
