High-speed Electric Spindle Unit Thermal Characteristics Of Research

High speed machine tool is the important achievement of advanced manufacturing technology, gradually becomes one of the developments of the manufacturing industry with a clear direction, and is the inevitable requirement of economic development. High speed machine tool has become the important supporting national economic development, the technology based equipment level is the measure of a national science and technology level and the level of productivity, but also promote an important mark of the equipment manufacturing industry rapid development of important factors. High-speed electric spindle is the key parts of high-speed machine, improve electric spindle one-dimenion thermal characteristics, in order to reduce the temperature electric spindle thermal deformation is the current electric spindle one of the important research topics.This research for high-speed electric spindle one-dimenion thermal properties of temperature change, and the electric spindle form and position deviation analysis, the concrete content as follows:1. Through the main spindle unit of electricity heat sources analysis, design combined type temperature measurement program, complete to its main heat source temperature data collection.2. To electric spindle unit are ANSYS simulation analysis, obtains electric spindle unit temperature field and thermal stress distribution, and spindle key parts of temperature changes with time.3. Through the electric spindle unit temperature and thermal deformation data analysis, clarifies the influence factors of thermal deformation axis. And using the Lab VIEW software design temperature rise and thermal deformation data analysis system.4. Electric spindle unit of temperature control and error compensation is analyzed and discussed measures for improving electric spindle, and puts forward the measures one-dimenion thermal properties.
