Problems of Automatic Feeding of Asymmetric Hollow Bodies of Revolution at the End Faces of Workpieces

The article describes asymmetric workpieces of solids of revolution with ends of different diameters, having internal cavities, and types of previously known mechanical disk hopper feeding-orienting devices for automatic feeding of workpieces, similar in shape to those considered. The principle of operation of such feeding devices is considered and problems arising when orienting asymmetric workpieces of solids of revolution with ends of different diameters having internal cavities are described. The invention presents an improved hopper feeding device with an inclined disk, radially located gripping members and an annular slot on the periphery of the base for volumetric billets with ends of different diameters, having internal cavities, and its improved device with a curvilinear cam, which can be adjusted depending on dimensions and position of the billet center of mass. Disadvantages of improved hopper feeding devices are described when feeding asymmetric workpieces of solids of revolution with ends of different diameters, having internal cavities, and problems arising during design.
