CCD (Charge Coupled Device) photography measurement module of superfine electric spark machine tool

Abstract

The invention relates to a CCD (Charge Coupled Device) photography measurement module of a superfine electric spark machine tool, which is particularly used for the measurement of the diameter of a wire electrode of the superfine electric spark machine tool. The CCD photography measurement module comprises a base plate and a connecting plate, wherein the connecting plate is positioned on the base plate and is provided with a vertical sliding table; the sliding table is provided with a supporting table fixedly connected with the sliding table; the supporting table is provided with a camera; the camera is provided with a mounting plate; and the mounting plate is fixedly connected with the supporting table. In the invention, a main shaft is provided with the wire electrode and drives the feed of the wire electrode; both sides of the wire electrode are respectively provided with a reflecting sheet and a camera which is a CCD camera, the diameter of the wire electrode can be accurately measured through the corresponding matching of the camera and the reflecting sheet, and measuring and machining accuracy is high; the camera enlarges the range of measuring the wire electrode by the camera through the corresponding matching of the vertical sliding table and a vertical regulating handle, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to a measurement module, in particular to a CCD (Charge Coupled Device) camera measurement module for an ultra-fine electric discharge machine tool, specifically for measuring the diameter of an electrode wire of an ultra-fine electric discharge machine tool, belonging to mechanical Technical field of processing. Background technique [0002] The principle of EDM is based on the electro-corrosion phenomenon during the pulsed spark discharge between the tool and the workpiece (positive and negative electrodes) to remove excess metal to achieve the predetermined processing requirements for the size, shape and surface quality of the part. [0003] EDM is mainly used to process molds and parts with complex-shaped holes and cavities; process various hard and brittle materials, such as cemented carbide and hardened steel; process deep fine holes, special-shaped holes, deep grooves, and narrow seams and cutting thin slices etc. The mic...

Problems solved by technology

The processing of micro-holes is a micro-scale process, and it is difficult to observe with the naked eye. Auxiliary means must be adopted, and the measurement of tiny electrode wires also requires auxiliary tools.

[0004] Since the main function of the ultra-fine EDM machine tool is the processing of micro-holes, the diameter of the holes is at the micron level, and it is difficult to identify them with the naked eye. The processing operation is inconvenient, which affects the processing and production efficiency.
