Abstract: In order to meet the production requirements of surface defects detection of the steel ball used in bearings

the method of SolidWorks parametric modeling based on VB is applied to realize the serial application of automatic detection system of steel ball. Firstly

establishing the template model library of steel ball automatic detection system

and the library is divided into general parts model library and key parts design library through analyzing the function structure

using SolidWorks part design table function realizes parametric design of key components; Calling the model library to complete the establishment of detection system virtual assembly model

and using SolidWorks macro function to make the driver program of key parts and assembly model

Finally

the simulation technology is used to simulate the process of steel ball

and the correctness of the theoretical analysis results is verified Finally

the parametric design method of automatic detection system of steel ball is put forward
