The implication of each Reference numeral sees the following form among the figure:
The specific embodiment
As shown in Figure 1, laser rotary-cut drilling equipment, laser instrument are the Q-switched pulse laser of pulsewidth less than 20ns; The output of laser instrument is provided with beam expanding lens 1; The output that the output of beam expanding lens 1 is furnished with 45 degree completely reflecting mirrors 2,45 degree completely reflecting mirrors 2 is furnished with optically-active system 3, and optically-active system 3 comprises the first wedge prism 31, the second wedge prism 32, the 3rd wedge prism 33 and the 4th wedge prism 34; The first wedge prism 31 is the identical wedge prism of the angle of wedge with the second wedge prism 32; The first wedge prism 31 or the second wedge prism 32 link to each other with straight-line motion mechanism up and down, can move up and down along axis, and the 3rd wedge prism 33 is the identical wedge prism of the angle of wedge with the 4th wedge prism 34; The 3rd wedge prism 33 or the 4th wedge prism 34 link to each other with rotating mechanism; A slice can be rotated around axis, and the output of optically-active system 3 is furnished with focus lamp 4, and focus lamp 4 is right against processing platform 5.
It is the picosecond laser of 532nm that laser instrument adopts wavelength, and the picosecond laser pulse width has high peak power, can make most material moment reach gasification temperature, and the heat-affected zone is little, in laser processing procedure, does not produce slag.The light beam that laser instrument sends is injected beam expanding lens 1; Beam expanding lens 1 output collimated light beam; Make specific angle of light deflection and displacement through optically-active system 3 again; Light beam is when a slice wedge prism, and light beam is the off-axis certain angle under certain condition, and then causes focusing on the back hot spot and depart from the central point certain displacement; The wedge prism focuses on the back hot spot and also makes circular motion around central point when axis rotates, form ring cutting.When light beam passed through a wedge prism group, light beam was with the off-axis certain displacement under certain condition, and the light after the focusing will incide on the work piece at a certain angle, focused on the angle decision ring cutting hole tapering of back laser beam; Focus to workpiece to be machined on the processing platform 5 by focus lamp 4, laser spot is positioned at surface of the work or interior.This device can be processed the micropore of diameter 30～500um on steel plate and other materials; Maximum diameter is dark in reaching 1: 20, can process the taper hole and the irregular taper hole of straight hole, different taperings.
Concrete steps are: laser irradiation from laser instrument goes out, and obtains the uniform light beam of collimation through beam expanding lens 2, gets into optically-active system 3 through speculum 2.Laser is parallel with optical axis to be incided in the optically-active system 3, and the rotating shaft of optically-active system 3 and light shaft coaxle, motor drive device and rotate around axis, makes the hot spot after the focusing also make circular motion along the axle center, forms the laser ring cutting; The size in the angle decision ring cutting aperture that turns over of the 4th wedge prism 34 wherein.The distance of the first wedge prism 31 or the second wedge prism 32 can be through linear motor driving control.The first wedge prism 31 and the second wedge prism 32 act as the direction of propagation that makes laser depart from the rotating shaft certain distance and do not change laser.And then control focuses on the direction of propagation of back laser; Can control the tapering that laser is got the hole indirectly like this.In the ring cutting process, the relative angle of the distance of the first wedge prism 31 and the second wedge prism 32 and the 3rd wedge prism 33 and the 4th wedge prism 34 can be adjusted in real time, can get aperture, the variable pass of tapering like this.The single pulse energy of pulse laser is greater than 100uJ.The focus of laser is positioned at the machined surface near surface.Punching is contracted gas to take away gasification or crushing material at the machining area blow pressure simultaneously.
Machining state in the process as shown in Figure 2,3 runnings of driven by motor optically-active system make in laser spot and also on machined surface, make the high speed circular motion, form rotary-cut.The size of control wedge prism adjustment hole.In processing simultaneously, need gasification and cracked material be removed rapidly to the machining area blowing compressed air of workpiece by blowning installation 6, in order to avoid the processing below the influence.Along with the increase of working depth, focus lamp also moves down thereupon, remains laser spot and is near the machined surface, thereby can keep very high working (machining) efficiency, obtains quality edge effect preferably.
The utility model equipment is used for workpiece is carried out laser rotary-cut punching; But can process the hole and the irregular taper hole of straight hole taper mutation; To obtain size variable, controlled, the entire laser boring effect of tapering; Solved efficient and tapering problem in the laser drill process, also enlarged the application of laser drill simultaneously at little manufacture field.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
