Description
Technical field
The utility model relates to a kind of accurate diced system of laser three-D of metal thin tube, has a wide range of applications on medical stent and experiment apparatus.
Background technology
The fine cut of metal is a research focus of little processing circle always, along with the development of laser technology, laser cutting is owing to the advantage of uniquenesses such as its cutting speed is fast, the laser fine cut is narrow with its joint-cutting, the heat affected area is little, otch is bright and clean, cutting speed is fast, flexibility is good, pollution is few becomes process technology emerging in the metal fine cut.
And the fine cut of a metal thin tube Recent study field of heat especially.Except as the various experiment apparatus, an application background that comparatively attracts people's attention is the cutting of medical science intravascular stent.Intravascular stent is used more and more widely in the treatment of cardiovascular disease, both at home and abroad carries out relatively extensively to the research of the cutting technique of angiocarpy bracket.
What use at present mostly is that the YAG laser instrument cuts metal thin tube, and use that the weak point of YAG laser instrument is that beam quality is poor, the heat affected area is big, conversion efficiency is low, poor stability etc., influenced cut quality, be difficult to obtain high-quality cutting effect.Also have simultaneously that noise is big, cost is higher, need water cooling plant, volume is big and will take bigger shortcomings such as space.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective of existing cutting method, and a kind of accurate diced system of laser three-D of metal thin tube is provided, and native system has good beam quality, simple in structure, conversion efficiency advantages of higher.
To achieve these goals, the utility model has been taked following technical scheme.Include optical fiber laser 10, laser instrument control system 20, computer 30, precision machine tool 70, machine tool control system 40 and laser work head 50; Wherein, laser instrument control system 20 links to each other with optical fiber laser 10, and machine tool control system 40 is connected with precision machine tool 709, and computer 30 is connected with machine tool control system 40 with laser instrument control system 20 respectively; Optical fiber laser 10 by optical fiber 110 be fixed on precision machine tool 70 on, the laser work head 50 that can do translational motion under lathe 70 drives is connected, workpiece 80 is fixed on the rotor 90 on the precision machine tool 70 and is positioned at the below of laser work head 50, can rotate under rotor 90 drives.
Air supply system 60 is connected with air inlet on the laser work head 50 by gas delivery tube 120.
The laser of described optical fiber laser 10 outputs is continuous laser or pulse laser.
Because the utility model adopts semiconductor pumped optical fiber laser as light source, it is simple in structure, and volume is little, the conversion efficiency height, and laser beam quality is good, can pass through fiber optic conduction, and the life-span is long, and is non-maintaining.The lathe of combined high precision overlaps control systems by software instruction two again, and then the running of output of control laser and workpiece, by reaching both relative three-dimensional motions, has realized the three-dimensional retrofit of metal.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Employed term " tubule " is not more than the hollow straight tube that 4mm, thickness of pipe wall are no more than 1mm for Guan Jing in the present embodiment.
As shown in Figure 1, present embodiment comprises optical fiber laser 10, machining software, laser instrument control system 20, precision machine tool 70, machine tool control system 40, air supply system 60 and laser Machining head 50.Arrive laser controller 20 by the working software output order on the computer 30, make it regulate optical fiber laser 10 bright dipping on request, this restraints high-quality light beam and arrives on the laser work head 50 that is integrated on the precision machine tool 70 through conduction optical fiber 110, focuses on output by its inherent focusing system and is radiated on the processing work 80.At this moment, the instruction of computer 30 output arrives machine tool control system 40, makes its control laser Machining head 50 do translational motion by demand, and simultaneously, the rotor 90 on the control precision machine tool drives workpiece 80 and rotates, thereby has realized the relative three-dimensional motion of workpiece with laser beam.When needs, computer 30 exportable instructions, can by air supply system 60 output assist gas through gas delivery tube 120 pass to the laser work head on the integrated air inlet.
Under the control of laser instrument control system, the laser beam of a branch of high light beam quality that optical fiber laser sends, this laser beam is had an effect with it on workpiece 80 through laser work head irradiation 50.Moving machining software simultaneously, by the running of work precision machine tool, specifically is laser head 50 parallel motions that are integrated on the lathe, and workpiece 80 rotates under the drive of lathe, and the two is in conjunction with having realized relative three-dimensional motion.Thereby realized the three-dimensional fine processing of laser to it.
