Abstract
One of the main indicators of the quality of technological equipment is reliability, stability and performance. These quality indicators applied for the lines of automated assembly of multicomponent products are provided by systems for automatic feeding of components to be assembled (parts, blanks, machining items), which are mostly either delivered to production in a non-oriented position in bulk, or lose their orientation at process steps, when performing operations of the production process. Similar systems are used in the product control of mass production in inspection machines. A main device of such systems is a hopper feeding device that orients parts. A reliable passive orientation of implicitly asymmetric parts is ensured by removing them from grippers subject to the following conditions. Firstly, the design of the gripping and orienting elements should ensure that the parts in the upper part of the hopper fall back by gravity into the lower part of the hopper, the gripping zone. Secondly, the parts partially sunk into the pocket in the wrong position should completely leave not only the gripping element, but also those structural elements of the hopper feeding and orienting device that are involved in preparing the parts for gripping. Therefore, the most important task in designing reliable structures of hopper feeding and orienting devices for implicitly asymmetric parts is to develop mathematical models of the passive orientation process to determine the conditions, when a non-oriented part should be completely removed from the gripping and orienting elements. The paper presents a method of building a mathematical model of passive orientation for a stepped cylindrical part using Lagrange equations of the second kind and their numerical solution to assess the conditions for a reliable operation of the hopper feeding and orienting device with radial rectangular pockets and grooves in the form of a rack.
