Abstract

The invention discloses a device and method for improving the laser drilling quality of plates and relates to the field of laser manufacturing. The device comprises a base, base bolt holes, big support bolts, big supports, big support bolt holes, small support bolts, small supports, locking bolts, rubber blocks, an upper cover plate, a workpiece, a lower cover plate and bearing plates. The big supports and the small supports are adjustable in mounting position, the laser drilling needs of workpieces with different thicknesses and different lengths can be met, and the device and method are especially suitable for laser drilling of the plates. Meanwhile, the invention provides the method for improving the laser drilling quality of the plates through the device for improving the laser drilling quality of the plates. The method solves the problems that too many splashes exist at holes during laser drilling, microcracks exist at the holes, the holes are in a horn shape, and the splashes areremained at hole outlets, the micropore taper is reduced, and the micropore circular degree is increased.

Description

technical field [0001] The invention relates to the field of advanced laser manufacturing, in particular to a device and method for improving the quality of laser drilling of plates. Background technique [0002] Laser microhole manufacturing technology refers to the use of pulsed laser beams to irradiate the surface of workpieces. Because the energy density of the focused laser beams is extremely high, the temperature at the focal point will instantly reach thousands of degrees Celsius. At this time, the vaporized metal will be sprayed out with the molten metal to form a hole. [0003] Laser microhole manufacturing technology is a new type of special processing technology, which has the advantages of fast processing speed, high economic benefits, wide range of processed materials, and no pollution. It has obvious advantages especially in laser group hole processing in the aerospace industry. However, there are many problems in laser drilling, such as more spatter at the or...
