Abstract
The utility model relates to a focusing light spot partitioning plate of a laser cutting head and belongs to the field of laser cutting machines. The alignment accuracy of focusing light spots is improved, the energy distribution of the focusing light spots is better partitioned, and machining quality is improved. The focusing light spot partitioning plate of the laser cutting head is characterized in that an annular focusing light spot partitioning plate body is arranged and is a round transparent glass plate with one or two concentric circles, and perpendicular cross division lines penetrating through the center of the round transparent glass plate pass through the concentric circles. Due to the fact that the concentric circles and the cross division lines are arranged on the round transparent glass plate, it can be ensured that laser light passes through the cross division lines and the center of a laser cutting nozzle and reaches the position, needing to be machined, of a workpiece, and meanwhile the state of the even distribution of the focusing light spots in the center can be easily checked through the concentric circles.
Description
Technical field
The focal beam spot division plate that the utility model relates to a kind of laser cutting head belongs to laser cutting machine field, and calibration plate, for the position of calibration laser light beam, improves laser beam and cutting head alignment precision, improves adjustment efficiency.
Background technology
Laser cutting machine is the high-tech product of modern industry processing, and it has replaced traditional machine cuts, has effectively improved working (machining) efficiency and crudy.The advantages such as laser cutting is wide with its cut coverage, cutting speed is fast, joint-cutting is narrow and cut quality is good, processing flexibility is large have obtained application very widely in modern industry.Wherein cutting head is the main parts of laser cutting machine, for guiding laser, and cutting processing material.
Laser cutting machine cutting head 1(Fig. 1) effect and operation principle be: the horizontal laser beam 2 that laser instrument 3 sends becomes laser beam vertically downward through the completely reflecting mirror 4 of 45 ° of cutting heads, focus on through lens 5 again, form the hot spot of high-energy-density, be irradiated on machined material 8 by cutting head 7 centers, the laser power density of focal beam spot 9 can be high by 10
6~ 10
9w/cm
2.The laser facula that is subject to high power density in the workpiece at its focus place irradiates, can produce 10000 ° of localized hyperthermias more than C, make workpiece instant vaporization, coordinate again auxiliary cutting gas that the metal of vaporization is blown away, thereby workpiece is cut and worn into a very little hole, along with the movement of Digit Control Machine Tool, numerous aperture couples together and has just become the profile that will cut.Because the frequency of laser cutting is very high, so each aperture junction is very smooth, the product glossiness cutting out is very high.Cutting assist gas produces a strong air-flow and blows off the slag of generation after cutting head nozzle water conservancy diversion, prevents that material gasification is attached to the surface of focus lamp, avoids it to be damaged simultaneously, in order to ensure the quality of products, the focusing of laser beam is wanted evenly, arrive exactly the position of material require processing by cutting head center, to make cutting head center aim at the center of focus lamp depth of focus, depth of focus refers to that focus both sides diameter is changed to 5% two spot center distances, in cutting, also claim effective cut coverage, existing laser machine is adjusted the position of laser focusing and cutting head so that the position of laser focusing arrival material is accurate by focusing alignment sheets, existing focusing alignment sheets 6 is circular hole slabs, orthogonal two wire 10(Fig. 2 of alignment sheets circular hole planar central), make the position of laser focusing arrival material accurate by adjusting aligning metal wire 10 crosspoints 11, laser cutting nozzle center, but, this focusing alignment sheets can only be calibrated both centers, simultaneously because wire diameter is thicker, can not make focal beam spot 9(Fig. 5) be uniformly distributed in cutting head center surrounding, affect to a certain extent cut quality.
Summary of the invention
The object that the focal beam spot of a kind of laser cutting head the utility model proposes is divided plate is: overcome the shortcoming of existing focal beam spot alignment sheets, the Energy distribution that improves laser alignment precision and divide better focal beam spot, improves crudy.
A kind of focal beam spot of laser cutting head is divided plate, comprise focusing alignment sheets, it is characterized in that having ring focusing hot spot to divide plate, described ring focusing hot spot division plate is one 1-2 concentrically ringed circular transparency glass plate, has orthogonal cross division line to pass through concentric circles by the center of circular transparency glass plate.
The focal beam spot of above-mentioned a kind of laser cutting head is divided plate, it is characterized in that circular transparency glass plate has a concentric circles, and concentrically ringed diameter is 1/2nd of circular clear glass board diameter.
The focal beam spot of above-mentioned a kind of laser cutting head is divided plate, it is characterized in that circular transparency glass plate has two concentric circles, a concentrically ringed diameter is 1/2nd of circular clear glass board diameter, and another concentrically ringed diameter is 1/4th of circular clear glass board diameter.
The utility model is owing to having concentric circles and cross division line on circular transparency glass plate, can ensure that laser arrives by cross division line and laser cutting nozzle center the position that workpiece need to be processed, meanwhile, concentric circles help check focal beam spot at center equally distributed situation.
