A Design About the Processing Technology of the pump body and the Special Jig
Abstract
This graduation project is about the overall process design of oil pump shell and the special fixture design of the process. Through access to various related books, analysis of the structure and function of the shell. After of parts for process analysis, draw up two sets of process route, through the analysis and comparison, select this in a more reasonable process route and batch production; And formulate process planning steps, determine moppet and develop process, determine the process of process equipment and auxiliary tools, determine the machining allowance for each process and calculate the process dimension and tolerance, finally determine the amount of cutting and cutting time. Fill in the process card and process card. On the basis of the development of mechanical processing technology, the design of a process of drilling jig. According to the characteristics of the parts of the layout, the use of a two hole positioning mode and the clamping way of the spiral plate. Finally, draw the assembly drawing and parts of the drilling jig.
Key words: processing technology; process; positioning; clamping; drilling fixture
