[Abstract]:The working conditions of electric hammer products are more complicated in the practical application process, so the requirements for various performance indexes of electric hammer are very high. However, there are many quality problems in domestic electric hammer, which mainly show that the continuous working time is short and the heat is easy to be generated. Easy to wear and vibration and noise and other aspects. In this paper, the magnetic impact technology is introduced into the electric hammer products, and a new type of magnetic impact hammer is proposed, which can realize the reciprocating impact movement of the impact parts through the magnetic impact mechanism. Compared with the traditional electric hammer, the magnetic impact hammer has the advantages of no friction and wear, simple structure, low noise vibration, environmental protection and no pollution. Combined with the project of National Natural Science Foundation, Zhejiang Province's important science and technology project and enterprise demand, this paper has carried on the concrete design to the magnetic impact type electric hammer's structure, has carried on the thorough research and the analysis to its impact performance. The analysis and optimization of the main parameters of the impact mechanism are also carried out. The full text is divided into six chapters: Chapter 1 describes the background and significance of the research, and summarizes the domestic and foreign research status of electric hammer products, magnetic drive technology, magnetic field numerical analysis methods, and analyzes the necessity and feasibility of the research on magnetic impact hammer. Chapter 2 introduces the basic principle of magnetic impact hammer, and designs the structure of magnetic impact hammer, including the structure design of magnetic impact mechanism and gear transmission mechanism. In chapter 3, according to the basic theory of electromagnetic field finite element, the three-dimensional finite element model of magnetic shock mechanism is established, and the distribution of magnetic field and the force of the mechanism under static condition are analyzed. On this basis, the cyclic calculation of the force during the whole dynamic impact process is carried out by using APDL language. In chapter 4, the effects of design parameters such as logarithm of magnetic pole, angle of distribution of magnet, minimum gap, radius of magnet and thickness of magnet on the impact performance of magnetic shock mechanism are analyzed. A quadratic response surface agent model is constructed. The design parameters are optimized. In chapter 5, the experiment platform is built, the force between permanent magnets of magnetic shock mechanism is tested, the correctness of simulation model is verified, and the process of making prototype is introduced. Chapter 6 summarizes the full text and looks forward to the next research work.
