ABSTRACT
This paper have a detailed analysis of the XZ25-50 gear box parts’ shape, structure, characte ristics and the various technical requirements. According to the production programe, the vist to the similar parts’ production process is had . By having parative bining to the equipment situation of business, it’s machining technology regulations are developed and the eightieth process’ rough boring special fixture is designed. In order to meet the process’ various technical precision, the fixture is adopted the form of a face two pin to give a reliable location, adopted the mobile plate to clamp the parts and used the oritented sleeve to achive the tool-orientation.

题目二:
ABSTRACT
The cone-thimble’s material, performance and technology characters during cone-thimble injection molding are analyzed, the structure of cone-thimble mold and design specialty ineach of its sub-systems are introduced separately. Importantly,to design the demoulding mechanism and pouring system in the structure of cone-thimble mold. According to the above analysis, mold is adopted a mold ten cavity point gate injection mold and adopted the pushing-plate and pound pushing- mechanism.
