Based On Servo Motor Driven Of Honing Oilstone Feeding System Of Research

Ac servo motor with a good speed control performance, high reliability and low maintenance costs are widely used in NC machine tool feeding system. In the honing machine of oilstone in the feeding movement driven by servo motor instead of the original hydraulic pressure drive. Improving the honing oilstone feeding of quick responsiveness and precision to achieved the purpose of high quality and efficiency machining. The servo motor driver honing oilstone feeding process was studied in this paper.First of all, aiming to the design of this honing oilstone feeding mechanism of servo motor drive. On the basis of analyze the honing machine of oilstone, according to the structure characteristics of the oilstone feeding mechanism, using the control pressure feeding and putting forward through the servo motor of current indirectly detecting honing oilstone feeding force.Secondly, the honing oilstone feeding process is divided into three systems: servo motor feeding system; mechanical transmission system; oilstone cylinder liner system. While honing oilstone feeding force and servo electrical current is the first and end of three consecutive of two parameter, so the three consecutive system were studied. In the servo motor feeding system, using the vector control principle to remove the nonlinear coupling relationship between the motor stator and motor rotor.As electromagnetic torque is produced by the stator, we can build the mathematic model of the input current to the output torque. This paper analyzed the linear and nonlinear problems of three systems, according to settle the relationship between the feeding fore of the servo motor input current and output to the honing oilstone. According to the actual working condition, Steady state(constant speed feeding) and Transient state (honing oilstone feeding force mutation) which were based on the current of honing oilstone feeding force of indirect measurement has been carried on the Maltlab simulation.The last of this subject adopts servo motor feeding process simulation, through the theoretical calculation to establish the current loop, speed loop and position loop transfer function model, and use the Matlab/Simulink software simulation to conduct the the step signal simulation of three links. It verified the rationality of parameter settings.
