Collision-preventing protection system and method for electric spark machine tool

Abstract

The invention discloses a collision-preventing protection system and a collision-preventing protection method for an electric spark machine tool. The collision-preventing protection system for the electric spark machine tool comprises a motor driver, a motion control card, a pulse power supply, a voltage meter and an industrial personal computer, wherein the industrial personal computer controls the motion control card; the motion control card is connected with the motor driver the pulse power supply respectively; the motor driver controls a main shaft to move up and down through a motor; the pulse power supply is connected with the positive electrode of an electrode wire and the negative electrode of a workpiece respectively; and the pulse power supply is connected with the external voltage meter and is used for observing the voltage condition. The collision-preventing protection system for the electric spark machine tool is a real-time monitoring system, saves shaft accessory exchange cost, shaft assembling and disassembling cost and maintenance cost, and guarantees the durable processing precision of a machine tool.

Description

technical field [0001] The invention relates to an anti-collision protection system and method for an electric discharge machine tool, belonging to the field of electric discharge machining. Background technique [0002] Tool collision of machine tool equipment, machine tool accidents where the spindle collides with the workpiece or tooling during motion. Knife collision will generally affect the accuracy of the machine tool and cause equipment damage more seriously. General machine tool equipment will use methods including machine tool hard limit, soft limit and photoelectric switch to prevent tool collision. [0003] The original anti-collision protection has the following disadvantages: 1) Due to the different shapes and specifications of the workpiece, the limit position may not be able to play a protective role; 2) When the operator misuses, the original anti-collision system cannot play a timely role Protective effect; 3) According to different fixtures, it is necess...
