In the process of design should first understand the analysis process of parts, and then design the blank structure, and choose a good location machining datum, the process route design of parts and parts of each step; process size calculation, and then through the &quot;info processing machinery concise manual &gt; find the corresponding tool and cutting the three elements to fill in the craft card; then design A special fixture, to design a specific folder, then design every relevant parts, such as the positioning element, the clamping element, the guide element, and then draw out the standard, calculation of location error of fixture location generated by the teacher to help find guidance for analysis on the rationality of the fixture structure is not enough, and then improve the design in the future.</p><p>Key words: worm reducer box &nbsp;process &nbsp;fixture &nbsp;positioning &nbsp;clamping &nbsp;error</p><p>目 &nbsp;录</p><p>摘 &nbsp;
