Design of brace processing technology and fixture for high speed printing press

Abstract: This design is a practical topic for enterprises. The topic comes from scientific research projects and practice. According to the design task book and the personal internship during the graduation design, the experience of the production project is designed, related to the knowledge of the various aspects of the professional courses I have learned, and the reference of the "mechanical manufacturing technology", "mechanical manufacturing process design handbook", "NC processing technology" and other documents, Yan Ge according to the "mechanical design manual", "cut" A variety of design specifications, such as the simple manual of cutting amount and the design manual of the machine tool jig, have been carried out, and the graduation design task has been successfully completed through the guidance of the instructor and the continuous revision of the update. After accurate calculation and experiment, the three-dimensional design of parts is carried out according to the requirements. The blank and processing technology of parts are analyzed. The reasonable processing technology, the setting of process parameters and the selection of tooling tool are formulated. According to the needs of production and processing, a new special rapid positioning fixture is designed to improve the processing efficiency.

The graduation design is the product of the combination of professional curriculum knowledge and social production experience. In the process, the instructor and the related people of the industry are supported and helped, and the comprehensive ability to analyze and solve the practical application problems in the engineering design is trained, and the application of 3D drawing software to draw engineering drawings and erect is improved. The ability of the body model enhances the ability to acquire practical information in Chinese and English literature and data, and has accumulated a lot of practical design experience.

Key words: Bracing; processing technology; fixture design;
