This design introduces a common link and fixture design process， the main content of ordinary material, connecting rod, connecting rod blank production method, the technical requirements and processing craft route formulation, processing equipment, cutting tools and measuring tools, cutting the amount of calculation, and design a set of processing link special fixture, and ultimately achieve the technicalrequirements of parts. Through the development of the connecting rod processing technology and fixture design and providesa basis for the working process of connecting rod. I want to design and process design for three link from the start process of drawing parts are analyzed, and through the look-up table, the calculation of blank material, manufacturing method of selection. Then according to the principle of selection of locating datum and the required precision, determine the processing base and processing method. And ultimately determine the processing route. Refer to the technical manual calculation to determine the machining allowance, three linkage process dimension and the blank dimension and drawing blank drawing, Machine tools and process equipment to determine and calculate the amount of cutting machining processes
