The ball screw is not only a key feature of the CNC machine tools, but also widely used in the aerospace, automotive and other industrial areas. The overall technological level of equipment manufacturing industry is rising in recent years, so that increasingly high performance requirements of the core components of the CNC machine tools, ball screw. The high speed is the main direction of future development of the ball screw, Speed at the same time positioning accuracy, temperature and noise performance will be affected to varying degrees affect, These parameters are directly related to the quality of the ball screw. At present, the dynamic characteristics of the ball screw test method is not perfect, has seriously hampered the development of the industry, therefore it is very necessary to analyze and study the integrated testing technology.
Combined with the relevant national standards and production of the actual need to meet the measurement characteristics and demands of high speed ball screw, this paper presents the design of a ball screw servo loading system to measure speed, acceleration, vibration, noise, temperature, deformation and screw the work load and other key parameters. Through the various test parameters, test principles and methods of analysis, Selected the equipment required, Such as motor control, as well as temperature, noise, vibration, micro-displacement, grating, angle encoders, and other kinds of sensors.
The development of high-speed ball screw servo loading system can be fully tested when the high-speed operation of the screw positioning accuracy, load capacity, stiffness, accuracy, efficiency and tightening torque, Provide a basis for improving the design of high-speed ball screw, ball screw performance.
Keywords: ball screw; servo loading system; Comprehensive testing methods
