基于固定支架工艺及钻Φ6mm孔夹具设计

AbstractThis design involves the knowledge of mechanicalmanufacturing process and fixture design,metal cuttingmachine tool,tolerance matching and measurement,etc.The process specification of support and the fixture designfor milling the right end face are three parts:the processdesign,the working procedure design and the special fixturedesign.In the process design must first analyze the parts,understand the parts of the process to design the structureof the blank,and choose a good part of the processingbenchmark,design the parts of the process line;Thencalculate the size of each working procedure of the parts,the key is to determine the process equipment and cuttingparameters of each working procedure;Then carry on thedesign of the special fixture,select and design eachcomponent of the fixture,such as the positioning element,clamping element,guiding element,clamping specificconnection parts and other parts with the machine tool;Thepositioning error is calculated,and the rationality anddeficiency of fixture structure are analyzed.Keywords:process,working procedure,cutting parameters,clamping,positioning,error.
