Laser electrochemical combined machining device with dual flow channels

Abstract

The invention discloses a laser electrochemical combined machining device with dual flow channels. The device comprises an optical lens, the inner annular flow channel, the outer annular flow channel,a through hole of the inner annular flow channel, a through hole of the outer annular flow channel, an annular electrode, an inner ring opening and an outer ring opening. The optical lens is locatedon the inner side of the inner annular flow channel, the inner annular flow channel is located on the inner side of the outer annular flow channel, the through hole of the inner annular flow channel is communicated with the inner annular flow channel, the through hole of the outer annular flow channel is communicated with the outer annular flow channel, the inner ring opening is communicated withthe inner annular flow channel, and the outer ring opening is communicated with the outer annular flow channel. The inner annular flow channel and the outer annular flow channel are used for conveyingchemical liquid for corroding slag and fragments stacked in the laser machining process; the annular electrode is located between the inner ring opening and the outer ring opening, and the potentialdifference exists between the annular electrode and a device to be machined. By adopting the unique design of the dual annular flow channels and the annular electrode, the application range of the chemical liquid is controlled, and the defects that a volcanic vent exists in the existing laser machining process, and the chemical corrosion precision is not good enough are eliminated.

Description

technical field [0001] The invention relates to a laser electrochemical compound processing device with double channels. Background technique [0002] Laser processing is a green and efficient advanced manufacturing technology, which is widely used because of its unique advantages. However, during processing, slag and debris tend to accumulate around the laser spot, forming a "crater". Laser electrochemical composite processing can eliminate slag and debris, but the chemical liquid nozzle in the prior art is open, lacks an effective recovery device, and the chemical liquid will flow and spread to other areas of the device to be processed, damaging the surface to be processed, At the same time, the non-precision design of the chemical liquid nozzle and the electrode will enlarge the laser etching aperture, making it difficult to improve the processing accuracy. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a laser ...

However, during processing, slag and debris tend to accumulate around the laser spot, forming a "crater"

The laser electrochemical composite processing can eliminate slag and debris, but the chemical liquid nozzle in the prior art is open, lacks an effective recovery device, the chemical liquid will flow and spread to other areas of the device to be processed, and damage the surface to be processed. At the same time, the non-precision design of the chemical liquid nozzle and the electrode will enlarge the laser etching aperture and make it difficult to improve the processing accuracy.
