Abstract

The invention relates to a device for implementing feeding of a machine tool, which comprises a PLC (Programmable Logic Controller), a stepping motor driver, a stepping motor, a lead screw pair, guide rails, a feeding sliding plate, a first Bluetooth module, a second Bluetooth module, a pulse generator, a first travel switch and a second travel switch, wherein the stepping motor is connected with the stepping motor driver; a rotating shaft of the stepping motor is connected with lead screws of the lead screw pair; the feeding sliding plate is arranged on the guide rails; a sliding block of the lead screw pair is fixedly connected with the feeding sliding plate. By adding the pulse generator between the PLC and the motor and changing a communication mode between the travel switches and the PLC, the technical problems of poor anti-interference capacity, limited feeding speed, complexity for data setting operation, fussy wiring between the travel switches and the PLC and the like, which are caused by the case that an existing machine tool adopts a PLC direct drive type control method to carry out feeding, are solved.

Description

technical field [0001] The invention relates to a device for realizing machine tool feed, which includes a PLC, a stepper motor driver, a stepper motor, a lead screw pair, a guide rail and a feed slide plate. 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 dis...
