Structural Optimization Of Honing Machine Pneumatic Gauging System And Analytical Investigation On Precision

Honing is a machining process of finishing. It can not only remove the reservedprocessing allowance, but also is a kind of effective processing method which canimprove the workpiece size, shape precision and surface smoothness. It is anindispensable process technology of honing technology, which has widely used onengine cylinder, the cylinder block hole, hydraulic cylinder and other precisionworkpiece processing. There have many factors to affect the machining accuracy ofhoning. One of the most important factor is pneumatic gauging system. Pneumaticgauging has a wide range of application on the area of honing cause its high gaugingprecision, good stability, and can realize non-contact gauging.Firstly, on the basis of fundamental principle of pneumatic gauging system ofhoning machine, get pneumatic transform link’ indicatrix, provide theoreticalfoundation of structural design and optimize. Use Gambit process grids divided, setboundary conditions and energy equation, aim at critical component, use FLUNTsimulation software to simulation analysis, sum up rules on pressure, velocity of thegas, change of the temperature. Last, use three section measuring, aim at all kinds ofshape of workpiece, establish it’s implementation methods, put forward prioritizationscheme of three section measuring, make use of C programming language to processprogrammable control, make the three section measuring get a very good application.Moreover, through to the analysis of the characteristic curve, put forward theconcept of balance time, and regard balance time as a target, analyse the relations ofguard board’s thickness, length, radius of curvature with it. Supply new thought for thestructural optimization of honing machine pneumatic gauging system.
