| Honing is a high efficiency, low cost processing method to improve the surface quality of the workpiece, the shape and the dimension accuracy Honing compared to many other cutting method has many oneās own knack in. With the development of honing technology and honing machine tool, honing has been more widely used in the processing of the cylinder, the inner surface of the engine bore.Large stroke double feed honing as an important tool in parts of large and medium-sized honing machine, which mainly include large mandrel, small ejector, big cones, small cone, coarse honing Whetstone seat, fine grinding and honing Whetstone seat body, etc. Its stiffness and strength is an important factor affecting the accuracy of the honing process. Large stroke double feed honing is developed on the basis of ordinary high precision double feed honing. Which has the characteristics of high cutting efficiency,strong honing pressure, high machining precision and low processing cost, so the study of the Large stroke double feed honing structure is an important way to improve the quality of the honing process.Based on the analysis of structural characteristics of large stroke double feed honing of the stroke in this paper, using Pro/e software to establish3D model for the stroke double feed honing and its large feed cone, large mandrel, coarse honing Whetstone seat, grinding bodies and other key Part. and import the model into Ansys Workbench software do statics analysis,Get the honing head and parts of the stress and strain state analysis result, analysis the influence on machining accuracy of the maximum strain, stress distribution,Obtain the basic approach of large stroke double feed honing structure optimization.on this basis, the large stroke double feed honing head in two modes for modal analysis at different spindle speed and constraints and to further optimize its structure, to achieve a improved static and dynamic characteristics. |
