DESIGN AND REALIZATION OF GRIPPERS WITH PERMANENT MAGNETS

Abstract

Urgency of the research. Modern production requires simple and inexpensive component solutions for gripping large parts. The design of gripping elements using a permanent magnet in this aspect is a promising direction. Target setting. The aim of the project was to realize a gripping component from a commercially available pneumatic drive supplemented with a neodymium permanent magnet and to revive the resulting assembly with a pneumatic portal manipulation device designed for educational activities at the department. Actual scientific researches and issues analysis. Implementation of the project required a detailed market research focused on the tentacles of a similar concept and the study of the principles and properties of permanent magnets. By analyzing the information the project objective was optimized - design of cheap and reliable gripping element. Uninvestigated parts of general matters defining. Available components were used for the resulting solution, with an emphasis on low acquisition costs. This was due to the fact that the output was intended for laboratory use. The research objective. The aim of the research was to build a real functioning and reliably working gripping device usable as an object for educational activities in the education of our students. The statement of basic materials. Design and practical implementation of the grippers with permanent magnets for gripping parts represented in the work. Activation and control of the grips is implemented by compressed air. The implementation of the output confirmed the correctness of considerations as well as the feasibility of the repeatability of this output while meeting the basic requirement for low costs. The project was based on the principles offered by leading companies, but the implementation output gives a higher gripping force at lower input costs. In addition, it provides the possibility of extension to the size range according to customer requirements. Conclusions. The project was successful and its implementation also contributed to the improvement of the educational process at the department, which was one of the monitored benefits. It provides an illustrative demonstration of the possibilities of performing manipulation tasks with non-standard objects.
