Bearing Parts Machining Process Valve Rocker Shaft and Its Typical Fixture Design
Abstract
Valve rocker shaft bearing is an important part of the diesel engine, is a combination of diesel engine rocker seat. This graduation design in valve rocker shaft bearing process design process, a detailed analysis of the process of the rocker shaft bearing, meet the technical requirements of the process was obtained through the comparison and analysis of the process, forming a machining process card and machining process card. And finish milling and turning and drilling fixture design, elaborated the localization scheme selection, clamping scheme, clamp design, AutoCAD is used to complete the assembly drawing of this typical fixture and clamp parts map specific. Processing technology of the design is reasonable, feasible， high efficiency, labor saving fixture, can meet the processing requirements of parts， ensure the machining quality.

Key Words: valve rocker shaft bearing; mechanical processing; processing
technology; typical jig
