Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art based on the embodiments of the present invention without any inventive step, are within the scope of the present invention.
Referring to fig. 1, a laser centering milling fixture, wherein the upper left device is a screen display device 16, the right device is a laser generator 11, the centered lens is clamped in two hollow fixtures with very high coaxiality precision, laser beams are emitted from the laser 11, pass through a focusing device 10 (with adjustable focal length), are refracted through a reflecting mirror at 90 degrees, pass through a hollow fixture shaft, pass through a centered lens 7, pass through a left hollow fixture shaft, and are directly irradiated to a conversion device 5 (with a micrometer capable of adjusting the X/Y direction), are subjected to photoelectric conversion, are instantly absorbed and converted into electronic current, the converted current is very weak, signal amplification is performed through an amplification factor knob 6, the laser beams are converted into green spots without glaring, the circular spots can be seen in a display 4, and are adjusted through a horizontal displacement knob 14 and a longitudinal displacement knob 15, the spots can be adjusted to the center of the screen of the display 4, the green circular spots can form a circular track when the high-speed rotation button 12 is turned on, and the smaller the circular track after the high-speed rotation is, the smaller the center deviation is represented.
When the laser centering device is used, due to the relationship between the refractive index of the lens and the magnification of the display, although the diameter of the green circular spot on the surface of the display 4 is increased, the final display is still high in precision, the green circular spot on the surface of the display 4 can do circular motion and can also do linear track movement, the horizontal displacement knob 14 and the longitudinal displacement knob 15 are adjusted on the display 4, the position of the spot can be adjusted, an operator can easily observe a rotating spot in a screen to adjust the clamping position of the centered lens 7 until the workpiece is adjusted to be clamped at the optimal spot rotating track, the laser centering work is finished and can be ground, the time for adjusting the clamping position is generally within 60 seconds, and the coordinates of the horizontal displacement knob 14 and the longitudinal displacement knob 15 in the screen of the display 4 are read per grid: the large grid is divided into five small grids, each small grid is 2mm, one large grid is 10mm, in order to see the rotation track of light spots on the screen clearly in the lens centering process, the large grid needs to be amplified, and the large grid needs to be adjusted by matching with an additional micrometer on a photoelectric conversion element seat, and the specific method is as follows: the final precision of the centering lens can be ensured by the method that the micrometer rotates by 10 lattices to be 0.1mm and the magnification K is 20/0.1 to 200 times. The precision of the laser centering instrument can reach 10' or even higher, the lens is centered by a laser beam, and a reading is displayed on a screen according to magnification, the reading is not a true angle-second precision value of the inclination angle of the lens surface, and the following calculation formula can be used for obtaining the precise angle-second value:
X＝10300*φ/[L*K(n-1)]
wherein: x: angle of surface inclination
L: distance from the lens to be machined to the photoelectric converter (machine tool is defined as 400mm)
K: magnification factor of display device
n: refractive index of lens
Phi: rotation diameter of green light spot in display screen
13000: calculating coefficients
For example: given that L is 400mm, K is 200, n is 1.7, and phi is 20mm, then
X＝10300*20/[400*200(1.7-1)]≈36″
In practice, the refractive index of the lens has a significant effect. For example, in the above calculation, if n is 1.8 instead of 1.7, X is 32 ″; if n is 1.6, X is 43 ", the effect of the refractive index can be seen from the change in the data.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
