Intelligent optical automatic wire threading device and wire threading method for medium-feeding wire cutting machine

Abstract

The invention discloses an intelligent optical automatic threading system and method for a medium-speed wire-cut electrical discharge machine. The system comprises an industrial camera, a two-dimensional moving mechanism, a wire clip and the wire-cut electrical discharge machine; the two-dimensional moving mechanism is movably placed on an XY numerically-controlled workbench of the wire-cut electrical discharge machine; a molybdenum wire clamped and fixed by the two-dimensional moving mechanism is clipped by the wire clip; and the industrial camera is located on any side outside the wire-cut electrical discharge machine. The method comprises steps as follows: (1) calibration; (2) calculation of a position deviation; (3) compensation of the deviation; (4) automatic threading. The threading method is simple, the position deviation is compensated by the aid of the threading system, the automatic threading function is realized, on one hand, the threading speed is effectively increased, on the other hand, the threading accuracy and quality are improved, the machining efficiency of the medium-speed wire-cut electrical discharge machine is greatly improved, the practicability is high, and the method is an innovation for development of the medium-speed wire-cut technology.

Description

technical field [0001] The invention relates to the technical field of intermediate wire cutting, in particular to an intelligent optical automatic wire threading device and a wire threading method for an intermediate wire cutting machine. Background technique [0002] With the development of science and technology, the emergence of various advanced manufacturing technologies has changed the traditional processing methods of many industries. In the wire cutting industry, in recent years, there has been no great breakthrough and development in technology. Another aspect is that there is no other more advanced processing method that can replace the processing method of wire cutting. Therefore, it is very necessary and valuable to carry out technological innovation and upgrading on the existing wire cutting equipment. [0003] During the wire cutting process, a through hole is pre-drilled on the workpiece, and then the tool electrode, usually a molybdenum wire, is manually th...
