淬火類材料深小孔振動鉆削技術(shù)與工藝實驗研究
[Abstract]:With the rapid development of aerospace, instrument, military, medical and other industries, higher requirements are put forward for the high hardness of quenched materials and the deep hole processing of hard to be machined materials. On the basis of summing up the development of deep hole vibration drilling at home and abroad, this paper studies the machining mechanism of vibration drilling, establishes the mathematical model of vibration drilling, and analyzes the machining accuracy and vibration chip breaking mechanism of vibration drilling. Variable speed cutting characteristics, variable angle cutting characteristics and bit static, rigidity effect. It is proved theoretically that vibration drilling has the advantages of high drilling precision, good chip cutting effect, good machining quality of hole surface, small outlet burr, long service life of bit, and so on. Based on the above analysis, the high frequency axial vibration system is designed by using the analytical method. The dynamic characteristics of the vibration system and bit are simulated and analyzed by ANSYS-Workbench software, and the design of the vibration drilling test device is completed. In order to study the drilling rule of deep hole with different hardness and quenching thickness, 45 # steel was used to make drilling specimen, surface quenching heat treatment with different hardness and different quenching depth was carried out, and the contrast test between vibration drilling and ordinary drilling was carried out. By analyzing the hole diameter difference, outlet burr, hole surface roughness and chip, it is proved that the hole processed by vibration drilling has smaller aperture difference, lower hole surface roughness and better chip removal effect. The influence of hardness of drilling material, spindle drilling speed and feed rate on the surface roughness and tool wear of the drilling hole is studied by means of the contrast test of vibration drilling with single factor test method, and the effect of drilling material hardness, spindle drilling speed and feed rate on the surface roughness of drilling hole and tool wear is studied. It provides a basis for the development of deep hole vibration drilling technology for quenched materials.
