Machine feeding control method and implementing device thereof

Abstract

The invention discloses a machine feeding control method and an implementing device thereof and belongs to the technical field of cutting machines. The conventional typical machine feeding adopts a programmable logic controller (PLC) direct-drive control method which has low anti-interference capability and a low feeding speed and is limited in precision and complicated in operation. In the invention, a feedback indirect-drive control method is adopted; a PLC is connected with a pulse generator through a wire to control the start and stop of the pulse generator; the pulse generator is connected with a driver of a stepper motor through a wire to send a pulse signal to the driver of the stepper motor; the driver of the stepper motor is connected with the stepper motor to drive the stepper motor to rotate; a rotating shaft of the stepper motor is in threaded connection with a screw pair; a feeding slider is arranged on a guide rail; a screw pair slider is fixedly connected with the feeding slider; and two travel switches are arranged on the two ends of the guide rail to sense the position of the feeding slider and connected with the PLC through wires to feed signals back to the PLC. In the invention, feeding speed and precision are high and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of cutting machine tools, and in particular relates to a machine tool feed control method and a realization device thereof. Background technique [0002] At present, the general machine tool feed mechanism mostly adopts PLC direct drive control method, including slide plate, guide rail, screw pair and stepping motor. The lead screw of the screw pair is fixedly connected with the shaft of the stepping motor, and the rotation of the stepping motor is converted into the linear movement of the slide plate through the transmission of the screw pair; the stepping motor is connected with the stepping motor driver, and the stepping motor driver is connected to the PLC through wires. Connection; when the machine tool is in feed motion, the PLC sends pulses to the stepper motor driver, and the stepper motor drives the stepper motor to rotate according to the number of pulses, and the feed movement displacement and f...
