Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, an automatic control device for the displacement of contact force in EDM surfacing mainly consists of a mechanical system and an electric control system 16, wherein the mechanical system includes a feed mechanism 1, a floating elastic mechanism, a torch clamping mechanism 7 and a welding torch 11. The feed mechanism 1 is mainly composed of a feed screw, a feed slide, and a feed base. The feed screw is arranged on the feed base, and the feed slide is driven to move by the rotation of the feed screw; The floating elastic mechanism is mainly composed of an upper base 5, an optical axis 14, a linear bearing 15, a lower base 10, a spring 4, and a floating slide 9. The upper base 5 and the lower base 10 are parallel to each other, and there are two left and right The optical axis 14 is connected (the optic...

Abstract

The invention relates to an automatic control device and control method for converting contact force into displacement during electric spark deposition bead weld. The automatic control device mainly comprises a feeding mechanism, a floating elastic mechanism, a gun clamping mechanism, a welding gun, an electric control system and the like and converts the contact force between an electrode and a workpiece into displacement of a floating sliding table. A non-contact displacement sensor is adopted for detection, conversion from tension and pressure measurement to displacement measurement is achieved, the strength of a mechanical system is improved, and measurement of micro contact force can be achieved. The contact force between the electrode and the workpiece is determined according to the displacement of the floating sliding table, a controller and the feeding mechanism are used for controlling the electrode to move along the axis of the electrode, closed-loop control over the contact force is achieved, and vibration between the electrode and the workpiece can be reduced through spring damping of the floating elastic mechanism; and the stability and reliability of automatic control of the contact force between the electrode and the workpiece in the deposition process are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of electric spark deposition surfacing welding, in particular to an automatic control device and control method for electric spark deposition surfacing welding contact force transfer displacement. Background technique [0002] EDM is a processing method for removing materials. EDM surfacing is a surface strengthening technology developed on the basis of EDM. It can deposit and surfacing 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, etc., can also repair surface defects such as scratches, pitting, and out-of-tolerance on the surface of precision mechanical parts. [0003] Different from the EDM technology, the EDM surfacing technology requires the electrode to be in constant contact with the workpiece for discharge and deposition surfacing. The process of E...
