Abstract
The graduation design task is design of process and boring fixture of rocker shaft pedestal. This design prehensively applied the knowledge of correlated curriculum such as engineering graphic, mechanical design, mechanical manufacturing, engineering and mechanical geometry precision design. This graduation design detailed analysis process of rocker shaft pedestal. Process what is in keeping with technical requirements is selection paring and analyzing process scheme, to obtain the machinery process card and mechanical processes card. This design designed boring fixture of rocker shaft pedestal, expounds about the positioning scheme selection, determine the clamping schemes. Boring mould design and fixture pedestal design. Use pleted the assembly of this special fixture and part drawing of fixture base. In addition, the 3-D modeling designs of the part of the rocker shaft pedestal.
