Research on key technologies of magnetic power tools

摘要

To reduce the vibration and the hurt on operation person produced by power tools, a new mechanism, namely magnetic impact mechanism in power tool, was proposed. Firstly, the common structure of power tools is analyzed, and the strengths and weaknesses of two forms of power tools are shown. Secondly, according to design requirements of power tools, a novel of magnetic impact mechanism is designed based on magnetic effect principle. Finally, the corresponding of conceptual design and structure of permanent magnet are proposed. The result shows that the effectiveness of the application of mechanism in power tools.
