[Abstract]:Spatial indexing cam mechanism has many functions of transmission, guidance and control. It is a high speed and high precision intermittent motion mechanism, which is widely used in packaging, printing and lighting. The space indexing cam mechanism has a variety of advantages over the drive clearance movement mechanism, such as compact structure, good rigidity, good transmission precision, and can realize high speed motion and all kinds of motion rules. The spatial indexing cam mechanism mainly includes globoidal indexing cam mechanism, parallel indexing cam mechanism and cylindrical indexing cam mechanism. Some countries are more advanced and adopt technical security measures. The main research in China involves the equation of cam profile, pressure angle curvature analysis, manufacturing process analysis, kinematics analysis and so on. Based on the above analysis, this paper takes the cylindrical indexing cam mechanism as the research object, in order to improve the transmission accuracy and stability of the cylindrical indexing cam mechanism. The spatial coordinate transformation theory, 3D modeling method, modal analysis method and dynamic simulation analysis method are used. The computer modeling process and dynamic characteristics of cylindrical indexing cam mechanism are studied and analyzed. This method can reduce the danger and loss caused by the physical prototype trial production, shorten the design period and improve the design efficiency. The obtained data provide theoretical support for the design and installation of cylindrical indexing cam mechanism. In the course of the research, the three-dimensional solid modeling of cylindrical indexing cam mechanism is realized by Pro/E software, and the modal analysis of input and output shaft in cylindrical indexing cam mechanism is accomplished by ANSYS software. The virtual prototype of cylindrical indexing cam mechanism and the simulation analysis of rigid-flexible coupling model are realized by ADAMS software. The main contents of this paper are as follows: 1) the main structural parameters of the cylindrical indexing cam mechanism are analyzed in detail. Based on the spatial coordinate transformation theory, the profile equation of the cylindrical indexing cam is established by using the two-coordinate system. Based on this equation, the model of cylindrical indexing cam mechanism is established by Pro/E and assembled. 2) the virtual prototype model of cylindrical indexing cam mechanism is established by dynamic simulation analysis software ADAMS, and the correctness of the model is verified by comparing the simulation data with the theoretical data. 3) analyzing and studying the ANSYS modal analysis method of input and output shaft in cylindrical indexing cam mechanism. 4) the rigid-flexible coupling modeling method of cylindrical indexing cam mechanism is studied, and the rigid-flexible coupling simulation analysis is carried out in ADAMS for different structure parameters and different working conditions. The influence of different conditions on the dynamic performance of cylindrical indexing cam mechanism is analyzed.
