Flap wheel parametric modeling method

Abstract

The invention discloses a louver wheel parameterization modeling method. The method comprises the steps that firstly, a louver wheel geometric model is established according to the measured size of a base body of a louver wheel and the size and the number of abrasive belt pieces; the surface appearance of the abrasive belt piece of the louver wheel is observed, and the size of abrasive particles and the distribution distance of the abrasive particles are calculated according to the granularity and distribution of the abrasive particles; based on the measured size of the abrasive particles, a regular hexahedron base body is established and randomly cut, and the polyhedral abrasive particles in irregular shapes are obtained; rotating the abrasive particles at any angle to change the initial posture; the surface of an abrasive belt piece of the louver wheel geometric model is divided into virtual lattices, and the centers of abrasive particles fall on lattice points of the virtual lattices; the abrasive particles randomly vibrate in the two directions of the quadrangular virtual grid, and the height of the abrasive particles is moved to the actual edge exposure height; and a GUI plug-in is compiled, and it is guaranteed that after relevant parameters are input into a GUI interface, the louver wheel model based on the abrasive particle microstructure is automatically generated.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to a parametric modeling technology, in particular to a parametric modeling method of a louver wheel. Background technique [0002] The louver wheel is a grinding and polishing tool that adheres a certain number of abrasive belt pieces to the periphery of the cylindrical inner core through resin glue. The abrasive belt and binder in the louver wheel have certain elasticity, so that the contact with the workpiece during processing is in an elastic state. During the grinding process, the abrasive belt is subjected to comprehensive effects such as contact elastic deformation, chilled layer change, and surface extrusion, which ensures that the louver has multiple functions of grinding, grinding, and polishing, and has good self-sharpening and high grinding rate. High and low noise characteristics. For difficult-to-process types such as inner and outer circles and curved sur...
