Box-type parts are composed of the box seat lid whose structure isrelatively complex usually a number of dimensional accuracy and location of the relativelyhigh precision positioning pin holes as the relevant parts location or in the process ofpositioning. Therefore it is difficult for process workers to design the process and fixturedesign. This Paper requires thatquot with quality beg development with benefits seek to live on tostore quot under the prerequisite of guaranteeing the quality of element processing have raisedproductivity and reduced production cost is one of mainly direction of domestic andinternational modern machining technology developing. Through knowing and analysis theconfiguration of the casing part drawing for WH212 gear reducer，so as to analysis theprocess，make process explanation and analysis the technical requirement and the precision ofgear reducer. Then carry out the design of clamping apparatus and analysis the precision anderror for the processing of bearing hole and the base hole of the casing of gear reducer， thistechnology and the design result of clamping apparatus can apply in production requirement.
