The Part of the process, in machining plays a very important part of the process, prepare to reasonable or unreasonable, it directly relates to the quality requirements could eventually parts, The design of fixture is big, it is the indispensable part in relation to improve the efficiency of the machining. So both in mechanical processing industry is crucial link. The graduation design, the topic is I design process and fixture enclosure reducer design. This case is complex, volume parts structure. In order to improve production efficiency and reduce labor intensity, I design a drill fixture. The design manual is divided into three parts:
The first part is divided into the machining process of the specified procedures, including process, contents and procedure, mechanical manufacturing process planning of the type and the procedure formats, introduced the principle and procedure. The choice of the locating datum, the process route in the selection of surface machining method, the method of processing, sequence arrangement has been introduced in detail.
The second part of the machine tool's fixture design, the interpretation of the machine tool's fixture of the machine tool's fixture soup, composition and classification. The principle, workpiece position and orientation of the positioning error calculation of components for clamping device, the composition and clamping force of three factors are analyzed. In the process of surface in milling machining, Diameter 40mm in for more boring, The rest of the hole for division I face a fixture designed to facilitate the processing (in press).
The third part mainly introduces the process of parts processing, I choose the design is mainly for determination of casting billet, The timeliness, The preparation process route and the process of writing (card), whole process card technology in processing after inspection. In the process of calculation, and fixture design of mechanical concise manual of gb through alignment. In processing after mapped the perfect parts graph (A0). Under the limitation in the economic guarantee processing request.

Key words: process, process, and drawing parts fixture, toto...
