Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment：
The utility model provides a kind of atomizer back taper micropore laser rotary-cut processing machine, the device need not focus lamp it
Front increase rotating prism or rotating wedge, it is only necessary to control focus lamp and achieve that the laser pulse rotary-cut to atomizer micropore adds
Work.
The utility model provides a kind of Laser Processing that can realize fuel-injector for automobile engine back taper micropore rotary-cut processing
Device, the device includes laser generator 1, speculum 2, mirror assembly 5, nozzle assembly 7, motor component 8 is focused on, wherein gathering
The profile of burnt mirror assembly 5 is cylinder, and it includes focus lamp fixed support 3, focus lamp 6, the several portions of horizontal direction adjusting screw 4
Point, horizontal direction adjusting screw 4 has three horizontal levels for adjusting focus lamp, as shown in figure 3, when the level of focus lamp
After position changes, the position of photocentre 10 and optical axis 12 also changes therewith, and therefore the same mirror foci that focuses on also can move to new
On optical axis 12, known according to geometric optical theory, the light parallel with optical axis 12 is necessarily converged at a bit --- the focus of focus lamp,
According to the optical axis 12 of focus lamp 6 relative to the axis for focusing on mirror assembly 5 position, so that it may know focal position.To realize back taper
Micropore cuts, and we are adjusted to the laser beam that reflected mirror 2 is sent by laser generator 1 to focus on the symmetrical centre of mirror assembly 5
On axle, i.e., the axis that the center line of incoming laser beam 11 focuses on mirror assembly 5 with cylinder repeats, and is now made by adjusting screw 4
Focus lamp optical axis 12 produces a horizontal range with the axis for focusing on mirror assembly 5（Still keeping parallelism）, then focus is also inevitable exists partially
Focus on mirror assembly 5 axis one side --- on the optical axis of focus lamp, due to incoming laser beam 11 it is parallel with focus lamp optical axis 12,
Therefore the focusing laser beam 9 after the line focus mirror of incoming laser beam 11 is focused on necessarily converges at focus, at this moment starts motor group
Part 8 drive focus on mirror assembly 5 rotate about the axis thereof, then deviate the focus lamp 6 of this axis focus operation also necessarily around
The axle forms a circular motion, and this motion can just make the device cut out circular hole.As shown in Figure 3,4, laser beam Jing gathers
The laser beam 9 that focuses on after burnt mirror 6 is focused on is presented different incline directions because focus lamp horizontal level is different, and ultimately forms cone
Shape scans track, and then forms tapered micro holes, appropriate to adjust the distance between focus lamp and workpiece, it is possible to realize that back taper is micro-
The rotary-cut processing in hole is protection focus lamp and improves cutting technique quality, and nozzle assembly 7 coaxially blows auxiliary gas.
Used as a specific embodiment of the present utility model, in Figure 5, three horizontal direction adjusting screws 4 have been changed to two
Horizontal direction adjusts the combination of spring 13 and a horizontal direction adjusting screw 4.
As a specific embodiment of the present utility model, it is above-mentioned it is improved on the basis of, the horizontal direction adjusted by people
Adjusting screw 4 is changed to the DC motor assembly 14 with internal battery to drive, as shown in fig. 6, this improvement can change in real time
Sweep radius of the laser beam in conical scan is focused on, so as to realize annulus or disc scanning.
As a specific embodiment of the present utility model, it is above-mentioned it is improved on the basis of, horizontal direction adjusting screw 4 is changed to
Threadless horizontal direction adjusting rod 2 16, as shown in fig. 7, be connected with the piston of horizontal direction adjusting rod 1, when cylinder section
The stream air inlet of valve 18 and during cylinder 17 outlet of choke valve, piston promotes horizontal direction adjusting rod 2 16 to the left, so as to drive focus lamp
To left movement, when the outlet of cylinder choke valve 2 18 during cylinder one 17 air inlet of choke valve, piston pulls horizontal direction adjusting rod two
16 to the right, then focus lamp adjusts moved right in the presence of spring 13 in the horizontal direction, when simultaneously cylinder choke valve 17 and 18 is closed
When closing, piston is motionless, so as to keep focus lamp current location constant.
The above, is only preferred embodiment of the present utility model, is not to make any other to the utility model
The restriction of form, and any modification for being made according to technical spirit of the present utility model or equivalent variations, still fall within this practicality new
Type scope required for protection.
