Abstract

The invention discloses an electric control system for numerical control milling machine safety protection. The electric control system for numerical control milling machine safety protection comprises a safety relay, an emergency stop button, an amplifier, a numerical control system power-on relay, a numerical control system input / output (I / O) unit, a numerical control system, a Z-axis servo motor, a numerical control system power-off button, a numerical control system power-on button, a Z-axis servo motor contracting brake normally open contact and a switch power supply. The electric controlsystem for numerical control milling machine safety protection can effectively solve the problem that the equipment safety is low since an existing numerical control milling machine electrical control system can switch off a power supply of the numerical control system when the emergency stop button is not pressed yet and no fool-proofing measures exist.

Description

technical field [0001] The invention relates to an electrical control system for safety protection of a numerically controlled milling machine. Background technique [0002] At present, in the existing CNC machine tools, the single contact of the emergency stop button is generally used to control the CNC system and the servo drive unit to be in the emergency stop state, and there is no emergency stop circuit to control the brake circuit of the Z-axis servo motor, and the emergency stop button When it is not pressed, the power supply of the numerical control system can be cut off. There is no fool-proof measure, and the safety of the equipment is not high. Contents of the invention [0003] The purpose of the present invention is to provide an electrical control system for the safety protection of CNC milling machines, which solves the problem that the electrical control system in the county can cut off the power supply of the CNC system when the emergency stop button is no...
