Abstract
The invention belongs to the lens centering assembly and adjustment technology, and relates to a centering tool. The centering tool is composed of an elastic sleeve, a cross divisional board and a pressing ring, etc. The elastic sleeve has the certain conicity and is provided with a groove; the center of the cross divisional board is coaxial with the outer circle of the elastic sleeve; and the cross divisional board is tightly pressed by the pressing ring. As the elastic sleeve can be contracted, the fit clearance of the centering tooling and a corresponding hole can be effectively eliminated, thereby improving the precision of the centering assembly and the adjustment and being applicable to the batch assembly and the adjustment of products.
Description
Technical field
The present invention is a kind of high precision elastic centering division plate, belongs to lens arrangement and mounting technology field, relates to a kind of centering frock.
Background technology
An optical system often is made up of a lot of piece lens, requires the light shaft coaxle of each lens.In the optical system that contains the light path of turning back,, need use the lenses centering frock in order to guarantee the light shaft coaxle of each lens.Common lenses centering frock does not have resilient sleeve, and remainder is similar.But,, so just can't further improve the centering of lens and debug precision so part and common lenses centering frock always have certain tolerance clearance because part has tolerance.
Summary of the invention
The defective that the present invention exists at existing apparatus just and design a kind of high precision elastic centering division plate is provided its objective is that providing a kind of can effectively improve the frock that precision is debug in centering.
The objective of the invention is to be achieved through the following technical solutions:
This kind high precision elastic centering division plate, it is characterized in that: this device is by resilient sleeve, the cross-graduation sheet frame, the cross-graduation plate, control hand wheel, adjusting jackscrew and trim ring forms, the cylindrical of resilient sleeve is the conical surface, on cylindrical, have groove, the cylindrical of graduation sheet frame and the endoporus of resilient sleeve are joined work, monolateral gap is being not more than 0.003mm, the cross-graduation plate is contained in the graduation sheet frame, regulating jackscrew makes cross-graduation plate center coaxial with the cylindrical of resilient sleeve, and compress with trim ring, control hand wheel and graduation sheet frame be by being threaded, and moves forward and backward control hand wheel and drive the cross-graduation plate and move forward and backward.

Embodiment
Below with reference to drawings and Examples the present invention is further described:
Shown in accompanying drawing 1～3, this kind high precision elastic centering division plate, it is characterized in that: this device is by resilient sleeve 1, cross-graduation sheet frame 2, cross-graduation plate 3, control hand wheel 4, adjust jackscrew 5 and trim ring 6 compositions, the cylindrical of resilient sleeve 1 is the conical surface, on cylindrical, have groove 7, the endoporus of the cylindrical of graduation sheet frame 2 and resilient sleeve 1 is joined work, monolateral gap is being not more than 0.003mm, cross-graduation plate 3 is contained in 2 li of graduation sheet frames, regulating jackscrew 5 makes cross-graduation plate 3 centers coaxial with the cylindrical of resilient sleeve 1, and compress with trim ring 6, control hand wheel 4 and graduation sheet frame 2 be by being threaded, and moves forward and backward control hand wheel 4 and drive cross-graduation plates 3 and move forward and backward.
As shown in Figure 4, this optical system is made up of big object lens 8, Amici prism 9, laser alignment mirror 10, laser convergence mirror 11, catoptron 12 and laser pick-off parts.Return laser beam arrives Amici prism 9 behind excessive object lens 8, through laser alignment mirror 10 and laser convergence mirror 11, received by the laser pick-off parts at last after turning back through Amici prism 9.For the optical axis that makes this optical system after catoptron is turned back with laser pick-off parts light shaft coaxle, need to adjust the angle of catoptron 12.The diameter of the lens barrel that cooperates with the laser pick-off parts is φ 22
0 + 0.021, to fill in the lens barrel very close to each otherly in order to guarantee resilient sleeve 1, the cylindrical of resilient sleeve 1 is decided to be φ 22
-0.015 -0.005Tapering is 1: 2000, frock of the present invention is packed in the lens barrel, find the picture of frock cross-graduation plate of the present invention with microscope 13, at parallel light tube 14 of the place ahead placement of waiting to debug optical system, adjust parallel light tube 14, make the optical axis of parallel light tube and wait to debug the light shaft coaxle of optical system, adjust the angle of catoptron 12 then, and move forward and backward microscope 13, parallel light tube 14 graticules are imaged in the visual field of microscope 13 clearly, move forward and backward control hand wheel 4, the cross-graduation of cross-graduation plate 3 also is imaged in the visual field of microscope 13 clearly with hand.The angle of accurate adjustment catoptron 12 makes the cross picture of parallel light tube 14 graticules look like to overlap with the cross-graduation of cross-graduation plate 3 then.
Advantage of the present invention is: can effectively eliminate joining of centering frock and light modulation system's lens barrel to be installed Close the gap, improve lenses centering and debug precision, and the batch that can satisfy product is debug requirement.
