Signal conversion device used for split-type numerical control machine tool

Abstract

The invention discloses a signal conversion device used for a split-type numerical control machine tool. The signal conversion device is installed on the bottom of a control cabinet and comprises an input interface connected with a numerical control system. A numerical control system signal received by the input interface is transmitted to an output interface through an input signal processing unit and an output signal processing unit, and the output interface is connected with a lathe bed signal. The lathe bed signal is connected with an optical coupler of the numerical control system through a current-limiting resistor, and an output signal of the number control system drives a peripheral load through a relay. By means of the signal conversion device used for the split-type numerical control machine tool, efficiency of separation and assembly of the control cabinet and the lathe bed is improved, and technical requirements on operators are reduced; the input signal current-limiting resistor with a large heating value is arranged on the device, and therefore heat dissipation requirements of the number control system are reduced; and the relay used for driving large current is arranged on the device, and therefore radiated interference of the load to the number control system is reduced, and stability of the system is improved.

Description

technical field [0001] The invention relates to a signal conversion device, in particular to a signal conversion device for improving work efficiency, reducing heat dissipation requirements of a numerical control system, and increasing system stability when a split-type numerical control machine tool needs to reconnect signals during separation and assembly. Background technique [0002] When the split CNC machine tool is transported, the control cabinet and the bed need to be separated and assembled. Most of the IO signals of the control system are in the form of terminal blocks, so when the control cabinet and the bed are separated and assembled, the signal lines on the bed need to be disassembled and reinstalled. Due to the complexity of the wiring, the efficiency is low, and the requirements for the operator's technical level are relatively high; a large part of the heat generation of the numerical control system comes from the current limiting resistor of the input sign...

Problems solved by technology

Due to the complexity of the wiring, the efficiency is low, and the requirements for the operator's technical level are relatively high; a large part of the heat generation of the numerical control system comes from the current limiting resistor of the input signal. With the increase of the number of input signals, the heat dissipation of the numerical control system The requirement poses a greater challenge; most control systems integrate output control relays on the CNC system. Since the objects controlled by the relays are often high-current devices, electromagnetic radiation adds more difficulties to the stability of the CNC system.
