Clamping and positioning device for wire electrode of wire-cut electrical discharge machine capable of realizing rapid wire feeding

Abstract

The invention discloses a clamping and positioning device for a wire electrode of a wire-cut electrical discharge machine capable of realizing rapid wire feeding. The device comprises a device body; the device body sequentially comprises a wire penetrating part and a clamping part from top to bottom; a wire penetrating hole is formed in the top of the wire penetrating part; a groove is formed in the bottom of the clamping part and communicates with the wire penetrating hole; bolts are symmetrically arranged on side walls on two opposite sides of the clamping part; and ends of the bolts penetrate through the side walls of the clamping part to extend into the groove. With the structure of the device, the wire electrode can be effectively clamped, and meanwhile, problems that hands are hurt easily and the wire electrode falls off easily when the wire electrode is directly held by hand are solved.

Description

Technical field [0001] The invention relates to the field of wire electrode wire mounting, in particular to an electrode wire clamping and positioning device of an electric spark fast-moving wire cutting machine tool. Background technique [0002] The CNC EDM fast-moving wire-cutting machine tool is uniquely created by the Chinese and is widely used in domestic colleges and universities and small and medium-sized enterprises. Because its wire transportation method is cyclic reciprocating wire transportation, and the wire transportation speed is very fast, up to 8~10m / s, It is almost impossible to automatically install the electrode wire like the slow-moving wire-cutting machine tool. In actual production, the fast-moving wire-cutting machine tool generally uses manual pure manual installation of the electrode wire. That is, after the wire electrode is wound from the wire spool to the wire storage drum of the wire cutting machine, one end of the wire electrode needs to be pulled a...

AI Technical Summary

Problems solved by technology

There are two outstanding problems in this manual wire winding process: on the one hand, the electrode wire is a molybdenum wire of φ0.18mm. Because the molybdenum wire is hard, brittle, and thin, it is easy to fall off when the electrode wire is pulled by hand, and the electrode wire often appears. Bending and breaking, it is easy to cut hands if the force is too large, and the tension of the electrode wire is not enough if the force is small, the electrode wire will vibrate during processing, resulting in short circuit or even broken wire; on the other hand, the groove of the guide wheel is narrow, and the width of the groove is generally not large It is more than 1.5mm, and the diameter of the electrode wire is only 0.18mm. It is difficult to quickly and accurately locate the electrode wire in the narrow groove of the guide wheel in the wire winding, especially when the light is dim, the electrode wire positioning is more difficult.
