The processing technology of air compressor crankshaft andgrip designAbstractThe design for the air compressor crankshaft machining technology andfixture design,the crankshaft is one of the most difficult to machiningparts air compressor machine,the design for the single-throw crankshaft,in the crankshaft type structure is relatively simple,low machiningdifficulty,crankshaft blank by forging,then by turning,milling,drilling,reaming process completed,such as crude benchmark for clampingthe journal positioning at about the center line of the main journal andfine benchmark about by locating pin connection end center hole locationof the center line of the main journal,two Angle is 120 inclined oilhole plane tilted use special drill jig,This design jig design hasdrilling machine jig (processing shaft neck and crank arm inside oil hole)and special vehicle crank bed jig,drilling machine jig mainly by A typepositioning pin,B type double hole support plate,90 working Angle ofz-axis v-shaped block,with hexagonal head bolts with hexagonal nutclamping.Fixture design should be as convenient and simple as possible.Keywords:The crankshaft:Connecting rod journal:Processing technology:Cutting:Fixture design
