Rotary adjustable water waveguide laser processing device

Abstract

The invention discloses a rotary adjustable water waveguide laser processing device relating to a laser processing device. The rotary adjustable water waveguide laser processing device is provided with a laser, an inverted telescope, a lens cone, a pipe joint, a pressing sheet, flat glass, a water cavity, a first reflecting mirror, a focusing lens, a nozzle body, a positioning mortise and tenon, a compression screw, a nozzle fixing frame, a bracket, a water collector, a clamp, a numerical control platform, a camera, a water circulating device, a data acquiring, processing and controlling computer, an observation laser and a second reflecting mirror. When different processing zones are selected, light path adjusting links can be reduced, thus the efficiency is increased; the technical problems of narrow processing range and low efficiency in the background art part can be solved; the poor processing flexibility and other defects can be overcome; and in a cavity with a certain pressure for the equipment, stable water waveguide jet flow processing can be formed and laser can be guided to a laser region through water waveguide, thereby the application field can be widened and the efficiency can be increased to the greater degree.

Description

technical field [0001] The invention relates to a laser processing device, in particular to a rotary adjustable water waveguide laser processing device with the functions of laser drilling, cutting, welding and the like. Background technique [0002] Swiss Richerzhagen Bernold developed a water waveguide laser micromachining technology based on the combination of laser technology and water jet technology (see international patent WO 95 / 32834), which has been applied in the fine processing of some brittle materials and some difficult-to-machine materials. Application and promotion, traditional laser technology utilizes laser emitting equipment with different principles and produces lasers with different powers and wavelengths for different industrial applications. As an important branch of laser technology, water waveguide laser processing technology has been widely used in various fields of brittle materials that are easily affected by thermal effects, especially in automobi...
