Fig. 1 is the utility model preferred embodiment front view;
Fig. 2 be among Fig. 1 A to structural representation;
Fig. 3 is the utility model embodiment side view;
Fig. 4 sets up the second speculum embodiment front view for the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, the utility model embodiment provides a kind of focus adjustable laser plumb joint, comprise generating laser 1, light pipe 2 and focus lamp 3, light pipe 2 mainly is for delivery of the laser beam 11 that is sent by generating laser 1,3 light-emitting windows that are located at light pipe 2 of focus lamp, and on light pipe 2, also be provided with a governor motion 21, can change the position of focus lamp 3 by governor motion 21, thereby regulate focus 111 positions of laser beam 11.In actual production process, plumb joint generally all can have alignment error, and the influence that also can be subjected to material of focus lamp 3, like this when laser beam 11 focuses on through focus lamp 3, can there be deviation in the physical location of focus 111 and theoretical position, thereby influence welding effect.And the position of focus lamp 3 is adjusted in the effect by governor motion 21, and focus 111 positions after making laser beam 11 focus on are dropped on the former theoretical position, when making laser weld, the weld seam of weldment (not shown) is narrow, and the heat-affected zone is little, and welding quality is better.
Further, there is a bending structure 22 in the light pipe 2, in bending structure 22, be provided with some first speculums 4, and each first speculum, 4 parallel oblique setting, laser beam 11 passes to focus lamp 3 and focuses under the effect of each first speculum 4, under the effect of bending structure 22 and each first speculum 4, changed the light path of laser beam 111, laser beam 111 no longer is with original optical path straightline propagation.
Further, plumb joint has also comprised a drive unit 5, and drive unit 5 can order about light pipe 2 and rotate around axis.In normal conditions, weld seam on the weldment generally is made of straight line and circular arc, traditional plumb joint is that movement by workbench or manipulator realizes the movement to the weldment position during weldment in processing, and when weld seam during from straight bead to the transition of circular arc weld seam, common workbench or manipulator translational speed are fast inadequately, there is an interpolation process, makes that the weldering spot is even inadequately.And this plumb joint is under the effect of drive unit 5 and bending structure 22, can realize the welding of circular arc weld seam, and the rotation of plumb joint can accomplish that reaction speed is fast, speed can at the uniform velocity change, and then can be so that the quality of weldering spot be even, welding effect is good, and for some other erose weld seam transition welding, it is even also can to accomplish to weld the spot quality.Particularly, drive unit 5 can be DD motor, rotary cylinder and the rotary magnet etc. that are connected with light pipe 2, and its moment of torsion is all bigger, and the response time is fast.
Particularly, each first speculum 4 in light pipe 2 is 45 degree settings, the bending structure 22 easier processing of light pipe 2 like this.
Referring to Fig. 1 and Fig. 2, be provided with blowning installation 6 in the junction of drive unit 5 and generating laser 1 further, the gas of blowning installation 6 ejections enters in the light pipe 2, and is provided with some pore (not shown)s at the edge of focus lamp 3.In welding process; release guard gas in 6 pairs of light pipes of blowning installation 2; and appeared by the pore on the focus lamp 3; can form a kind of protection to weldment; and because laser beam 11 produces a large amount of heats in light pipe 2; easily each first speculum 4 in leaded light 2 pipes and focus lamp 3 etc. are exerted an influence; protective gas can form cooling effect to each eyeglass in the process of passing light pipe 2; avoid it to rupture because of overheated; usually protective gas can be various inert gases, also can be compressed air.
Particularly referring to Fig. 1 and Fig. 3, governor motion 21 comprises micrometer knob 211 and spring 212, also be connected a transverse slat 213 between micrometer knob 211 and the focus lamp 3, can form suppressing action to focus lamp 3, behind rotation micrometer knob 211, focus lamp 3 can move down, and behind reverse rotation micrometer knob 211, because of spring 212 effects, focus lamp 3 can move up, and spring 212 can be compression spring or extension spring, and when for the compression spring, spring 212 is positioned at the below of focus lamp 3, and when being extension spring, then it is located at the top of focus lamp 3.Certainly governor motion 21 can also be another kind of structure, comprise the adjusting nut (not shown), adjusting screw(rod) (not shown) and the rule (not shown) that are located on the light pipe 2, adjusting screw(rod) and adjusting nut are connected and are connected and fixed with focus lamp 3, behind the rotation adjusting nut, focus lamp 3 can move up and down, rule then is sticked on light pipe 2, displacement that can mark focus lamp 3.These two kinds of structures can realize the adjusting to focus lamp 3 positions, make the physical location of focus 111 be positioned on the former theoretical position, strengthen the laser weld effect, and structure are all fairly simple, and usually the moving range of focus lamp 33 is each 5 millimeters up and down.
Referring to Fig. 4, further, under focus lamp 3, can also set up second speculum 7 that is obliquely installed, can change the optical path direction after the focusing, make focus 111 positions not on original optical path, can be conveniently to vertically welding inconvenient weld seam in the weldment.
Particularly, also be provided with a collimating mirror 8 in light pipe 2, collimating mirror 8 is positioned at the top of focus lamp 3.Usually the laser beam that sends of generating laser 1 11 is divergent beams, and through under the effect of collimating mirror 7, divergent beams become collimated light beam, and directionality is better, and energy is more concentrated.
Further, when making plumb joint, can also connect the cone-shaped hood 9 with opening 92 at the light-emitting window place of light pipe 2, and offer for the straight blowing nozzle 91 of discharging protective gas at cone-shaped hood 9.After starting generating laser 1; laser beam 11 is just transmitted by the opening 92 of cone-shaped hood 9; and when welding processing; foreign object might occur enters in the light pipe 2; cone-shaped hood 9 has then prevented the generation of this kind situation effectively, can play the certain protection effect to each eyeglass in the light pipe 2.
Certainly in actual processing, for the plumb joint in the present embodiment, not only only be applied on the laser weld, also can play good effect for the cutting of laser and mark etc.
The above only is the utility model preferred embodiment; its structure is not limited to the above-mentioned shape of enumerating; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
