Embodiment Construction

[0016] The device mainly includes a laser generator (1), a light guide system, a workpiece fixture system and a control system. Wherein the light guide system includes a light guide pipe (3), a total reflection mirror (4) and an impact head (5), and the workpiece fixture system includes a constraining layer (water) (12), a plug (15), and an absorbing layer (black paint) (16), reflection cone (8), plug (17), workpiece (6), fixture (7), workbench (9) form, and control system comprises computer (11) and controller (10).

[0017] The laser generator (1) emits optimized laser pulses (2), the beam modes of the laser pulses (2) can be fundamental mode, multi-mode and other modes, which are regulated and controlled by the controller (10). The laser beam (2) produced by the laser generator (1) is irradiated on the reflection cone ( 8) On the energy absorbing layer (16) of the surface. There is a focusing lens in the impact head (5), and the size of the light spot can be changed by ch...

Abstract

The present invention is deburring method and apparatus based on laser shock wave technology and relates to laser machining technology. The present invention adopts the laser induced shock wave as the force source for deburring, and has laser generator controlled with one controller to generate laser pulse, light guiding system irradiating the laser pulse onto the absorbing layer of the reflecting cone, the absorbing layer to absorb laser energy to vaporize and ionize to form plasma, the plasma to further absorb laser energy to explode and to generate high amplitude shock wave eliminating burr in the surfaces, including inner surfaces, of parts. The present invention can eliminate burr, strengthen the surface, raise the hardness, lower the surface roughness and increase the service life of parts.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a method and device for removing metal cutting burrs based on laser shock wave technology, and is especially suitable for removing cutting burrs in inner cavities such as intersecting holes in parts. Background technique [0002] Cutting burrs are one of the common defects in cutting processing. With the miniaturization, multi-function and high precision of parts, the impact of cutting burrs on the quality of parts is more prominent. Burrs, like redundant objects, have a great impact on products. Affect or even endanger the reliability of the entire product, such as air bearings or dynamic pressure motors with small gaps. Due to the different parts of the burr formation, the difficulty of burr removal is different. The burr on the outer surface of the part, such as the burr on the outer circle, end face, plane, etc., the method of removing the burr is relatively simple, using tool...
