Problems solved by technology

However, the above-mentioned patents can only process straight holes, and cannot directly process streamlined channels. For example, if you want to process a flow channel where the direction of fluid advance is changed by 90 degrees, you can only use lasers to drill straight holes in two vertical directions, and then block them. unnecessary holes

Abstract

The invention relates to the field of laser processing, in particular to a laser processing device for a parabolic streamline hole, comprising a casing, a laser focusing lens, a laser window and a nozzle. A laser window is arranged on one side of the cavity, and a nozzle is arranged on the other side. An interface is arranged on the casing to communicate with the hydraulic equalization cavity. A laser focusing lens is arranged in the casing and outside the laser window. The laser is injected from the back end opening of the casing and irradiated in the nozzle after passing through the laser focusing lens, the laser window and the liquid in the hydraulic equalization chamber in sequence, and the casing outside the nozzle is provided with a jet port, After the liquid passes through the nozzle, a jet is formed and ejected from the jet port. The jet is bent by gravity to form a parabolic shape and is injected into the workpiece to be processed. The laser enters the jet and propagates along the direction of the jet. The invention bends the laser with the jet, and can efficiently realize the laser processing of the parabolic streamline hole.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a laser processing device for a parabolic streamline hole. Background technique [0002] Laser drilling processing technology has been widely used in the processing of various metal material channels. Due to the characteristics of laser propagation along a straight line, laser drilling processing technology has been widely used in straight hole processing. For example, the invention patent with patent number 201810987816.6 A laser drilling device and method based on a vacuum environment to improve the quality of hole making is proposed in the paper. This method introduces the laser into the vacuum environment to realize the processing of straight holes, effectively reducing the oxidation and nitriding that are easy to occur in laser drilling in air. The reaction improves the quality of the hole wall. Another example is the invention patent No. 201811340209.7, which discloses a dev...
