The Parametric Design and Motion Analysis about Line Translating Tip Follower Cam Mechanism Based on Model Datum Graph

Cam mechanism can get the expected movement law by means of higher pair touch drive follower. This paper used Pro/E's datum-graph function, to create the follower's displacement line graph, and to control cam profile by using the displacement line graph, the line translating tip follower cam mechanism was wholly parametric designed. The system can provide 16 kinds of typical combination motion law for users. The system can generate automatically cam profile according to the parameter imported by the consumer. Furthermore, using the technology of virtual assembly and motion simulation, the visible assembly structure analysis and performance evaluation can be realized in design phase.
