Abstract

This paper focuses on the design of the support clamp of the diesel engine, and defines the design objectives and difficulties through in-depth analysis of the function and process requirements of the parts. First, the key role of the parts in the diesel valve control system includes supporting the rocker shaft and connecting the cylinder head. Secondly, the process characteristics of the parts are comprehensively analyzed, including the processing requirements of the holes and surfaces, as well as the determination of the processing sequence. In the design process, combining CAD 2 D and SolidWorks 3 D maps to accurately geometric model and dimension the parts. The simulation analysis verified the fixture design and optimized the key structures. Finally, a set of fixture scheme is designed to meet the machining accuracy and efficiency requirements, which provides effective technical support for the manufacture of diesel engine joint. This study not only improves the manufacturing level of diesel engine, but also provides a useful reference for the clamp design of similar parts.
