Research on modeling method of Globoidal Cam mechanism

Abstract

Taking the globoidal CAM mechanism as the research object, this paper deduces the calculation equation of globoidal CAM contour surface and pressure Angle, and summarizes the general motion law of globoidal CAM follower. On this basis, the design software of globoid CAM is developed to realize the globoid CAM mechanism, including globoid indexing CAM, globoid deceleration CAM, globoid CAM with oscillating roller follower, as well as the contour data output of ATC multi-head globoid CAM, cutter position processing data output, and the verification of mechanism pressure Angle. Finally, ATC multi-head cambered mechanism is taken as an example to realize the establishment of its model and kinematic simulation, and the rationality of the design is verified.
