ABSTRACT
Diesel engine connecting rod is the key piece of sports, it works the stability, reliability is critical to the quality of the diesel engine machine, light weight, high precision, connecting rod, help reduce energy consumption and engine noise. The design specification introduces the domestic and international fixtures and the status of jigs and fixtures, fixture design purpose, meaning, some design principles and key data needed, mainly to explain the combination of surface tension rod fixture design process, including the connecting rod Processing technology, the calculation of the production program, connecting rod body pull mode with the choice of surface fixture, broaching processing program selected, the calculation of cutting force and determine the way broaching, broaching the calculation of processing time, the cylinder selected folder Tight inter-agency drive the choice of a small shaft and checking calculations, the final design brief summary of the results achieved and the advantages of this design, such as using a pneumatic clamping device, fixture on the future direction of development to give some suggestions.
Key words: connecting rod body with fine surface tension; fixture design; Process Analysis
