A Engine Block Surface Double-sided Horizontal Milling Machine Design

Engine Block surface double-sided horizontal milling machine is mainly processing for adomestic automobile factory No.480-1002015MA engine cylinder block about two face, isthe engine cylinder block casting in the first step in the automatic production line processing,is mainly to prepare for subsequent processing. The original machine for machining precisionand machining efficiency can not meet the demand, the need to redesign.This design mainly includes the following contents:1. The overall design of machine tools. According to the workpiece material, machiningparts production types, characteristics and technical requirements to determine the overallscheme of machine tool selection and cutting parameters, complete tool combination machinetools and machine tool dynamic analysis and calculation of components of hydraulic slipwayand dynamic milling head selection and calculation. And on this basis to draw thecombination machine "three charts and a card", namely process map, diagram processingparts, machine contact size map and productivity calculation card. Finally, to complete theaction cycle design of combination machine tools, according to the manufacturer’srequirements, the machine tool production rhythm is120S, completed the design ofconveying to after the completion of workpiece processing about30more action cycle fromthe installation work.2. Special fixture design of combined machine tool. Fixture design need to considerwhether the correct positioning of the workpiece, the positioning accuracy meets therequirements as well as determining the clamping force etc.. In order to reduce the auxiliarytime, clamping device of machine tool selection of hydraulic clamping form. The clampingforce on the fixture of the selection and calculation of the hydraulic clamping cylinder andcalculating, and then finished drawing the assembly drawing machine fixture.3. The fixture of the main stress components of hydraulic clamping plate of the finiteelement analysis, check its strength and stiffness is consistent with the actual processingrequest.
