Abstract

The invention relates to an automatic control device and a control method for the displacement displacement of the contact force of EDM surfacing, wherein the automatic control device is mainly composed of a feed mechanism, a floating elastic mechanism, a gun clamp mechanism, a welding torch and an electric control system, and the electrode and the workpiece The contact force between them is transformed into the displacement of the floating slide table, and the non-contact displacement sensor is used for detection, which realizes the transformation from tension pressure measurement to displacement measurement, which not only improves the strength of the mechanical system, but also realizes the measurement of tiny contact force; according to the floating The displacement of the sliding table determines the contact force between the electrode and the workpiece, and the controller and the feed mechanism are used to control the movement of the electrode along its axis to realize the closed-loop control of the contact force. The spring damping of the floating elastic mechanism can reduce the distance between the electrode and the workpiece. The vibration between the electrode and the workpiece significantly improves the stability and reliability of the automatic control of the contact force between the electrode and the workpiece during the deposition process.

Description

Technical field [0001] The present invention relates to the field of electric spark deposition staining technology, and more particularly to an automatic control device and a control method of electromechanical deposition stacked welding contact force transfer displacement. Background technique [0002] Electrical spark processing is a method of removing material. Electrical deposits are surface strengthening techniques developed based on electric spark processing, and can deposit and deposit special materials on the surface of the workpiece material, which can improve the hardness of the workpiece. Wear resistance, heat resistance, corrosion resistance, fatigue strength and service life, can also be repaired on surface defects such as scratches, pixes, and ultra-poles such as precision mechanical components. [0003] Unlike electric spark removal processing technology, electric spark deposition supporting techniques require electrodes to continuously contact and deposit welding....
