【Abstract】 This paper analyzes the parallel indexing cam design process,describes in detail the formation of cam contour and the contour of the data calculated.With VB as the software platform,the parallel indexing cam contour is calculated,the contour mapping is displayed,and the data format is saved as required.Then the parallel indexing cam mechanism is drawn up a three-dimensional entity directly in SolidWorks in order to achieve parallel indexing cam mechanism of the 3D parameterization design and motion emulation.This can help designers to find the problems,such as the rotation difficulties caused by excessive pressure angle,the motion distortion caused by small radius of curvature.So the designer can make changes in time,improve design quality,shorten product development cycles.The software platform can select type of the interval splitter by calculated and select power motor according to the input drive shaft angle and the output shaft such shares.The system has realized the transmission of information and shared information between s.ubsystems,enhanced the degree of integration and automation of parallel indexing cam design and manufacture.These provides a good software platform for parallel indexing cam mechanism’s design,manufacture and performance studying.Finally,the example of interval paper-feed mechanism in a automatic die-cutting machine verifies the usability and effectiveness of the software platform.更多还原
