Abstract

A kind of transducer control method and device used in principal axis of machine tool belongs to field of mechanical engineering. The method mainly modulates transducer to control output signal to modulate output frequency of transducer. At the same time motor rotate speed of machine tool can be modulated reversely, control circuit of transducer can not be affected by modulating circuit. Output of transducer modulated can drive principal axis motor rotate in definite rule, so resonance frequency of machine tool and principal axis box gear coupling oscillation can be avoided. The device includes transducer control circuit, inverter, frequency signal modulator, speed signal equivalentor, speed signal compensator and modulating rule setting machine. Structure is easy, control is convenient, and machine tool oscillation can be improved effectively.

Description

technical field [0001] The invention relates to a frequency converter control method and device for a machine tool spindle, belonging to the field of mechanical engineering. Background technique [0002] With the development of electronic technology, the performance of inverters used for AC motor speed regulation is also changing with each passing day. Its speed regulation range is wide, its precision is high, its response is fast, and its application range is wider and wider, and it is also more and more specialized. Based on this, many special models have been developed, such as special models for fans and air conditioners, special models for injection molding machines, special models for elevators, etc. These special frequency converters have made special designs according to the characteristics of their respective application fields. [0003] As the core component of processing machine tools, machine tool spindles are closely related to product quality, production effic...
