DETERMINATION OF RATIONAL PARAMETERS OF ELECTROMECHANICAL PUNCH LINKS WITH SHOCK-TURNING ACTION

Abstract

In this work, the subject of research is an electromechanical perforator with a shock-rotary action. The purpose of the work is to determine the rational parameters of the links of an electromechanical perforator with a shock - rotary action. Methods of analysis of kinematic diagrams, plan of positions of links of impact and rotary mechanisms of electromechanical perforator are investigated. As a result of the theoretical studies, rational parameters of the links of the rotary mechanism were selected. The rational value of the length of the connecting rod and rocker arm was determined, respectively equal to 70 and 30 mm, with the angle of rotation of the tool in one cycle equal to 55○, it was revealed that such a ratio of the geometric parameters of the links of the rotary mechanism allows providing a rational mode of operation of the electromechanical perforator. Based on the analysis of the results obtained, purposeful ways of creating highly efficient and promising designs of electromechanical perforators with shock-rotary principles of action have been identified. The research results are recommended by a research institute and amanufacturing enterprise engaged in the development and creation, as well as operation of manual electromechanical rock drills.
