Piston air compressor parts processing technology development-piston processing and fixture designAbstractBy analyzing the development background of the piston,the developmentstatus of the fixtures at home and abroad,and the structure of the parts,aprocessing route and a set of production plans for the piston are designed,whichmainly include:selecting the blank material,determining the blankmanufacturing method,selecting the rough and fine benchmark Draw up reasonableprocess lines,determine the machining allowance,determine the machiningallowance for each procedure,calculate the procedure time,etc.A set of specialfixtures for boring pin holes is designed according to the process of boringpin holes to ensure machining accuracy.It includes the specific design ofselected positioning components,clamping devices,standard parts and clamps.Finally,the rationality of the fixture is verified by analyzing positioningerrors and calculating clamping force.Keywords:Piston;process route;process;positioning;fixture design
