[0002] The optical system cannot do without the use and adjustment of lenses. At present, the coaxial adjustment method of lenses is to use tooling lenses to simulate the adjustment of lenses. After the coaxial adjustment accuracy is achieved, the tooling lenses are replaced with lenses. Tooling lenses are cylindrical mechanical tools with crosshairs and reflective surfaces.

[0003] The detailed process of the coaxial adjustment method of the lens is as follows: install the tooling lens in each independent lens holder through the lens frame, place the lens holders installed with the tooling lens in sequence on the flat bottom plate through adjustment pads, use a theodolite to observe the center position deviation of the crosshairs of each tooling lens and the angle deviation given by the reflecting surface, adjust the thickness and angle of the adjustment pad to ensure the coaxial accuracy of the center of each lens holder, transfer the virtual optical axis center to the lens holder and the flat bottom plate through the tooling lens, and realize the coaxial adjustment of the lens group.

[0004] Since different optical systems use lenses with different diameters, the corresponding inner diameters of lens mounts are also different. Each time, it is necessary to redesign and produce a frame with the same diameter according to the diameter of the lens, so that the tooling lenses can be installed in the inner holes of lens mounts with different inner diameters through frames of different sizes. For optical systems that are not mass-produced, it is difficult to reuse a frame of a certain size after installation and adjustment, which seriously causes a waste of resources.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] like Figure 1-8As shown, the present invention provides a lens adjustment and multiplexing device 14, comprising a housing 1, a driving gear 2, a gear pressure ring 3, a force storage spring 4, a preload spring 5, a toothed claw 6 and a moving handle 7; wherein, a tooling lens 8 is fixed inside the housing 1 by a lens pressure ring 9; the driving gear 2 is rotatably connected inside the housing 1 and is located on the outer ring of the tooling lens 8, and the moving handle 7 passes through the housing 1 from the outside and is connected to the driving gear 2 for operation by a staff member to drive the driving gear 2 to rotate; the gear pressure ring 3 is fixed inside the housing 1 and is coaxial with the driving gear 2, and is used to axially limit the driving gear 2; the force storage spring 4 is evenly distributed along the circumference of the gear pressure ring 3, and one end of the force storage spring 4 is connected to the driving gear 2, and the other end is connected to the driving gear 2. The end is connected with the gear pressure ring 3, and the storage spring 4 is used to provide restoring force for the driving gear 2. When the staff releases the moving handle 7, the driving gear 2 rotates to complete the reset; the toothed claw 6 is evenly distributed along the circumference of the gear pressure ring 3, and both ends of the toothed claw 6 are arc-shaped structures. One end of the toothed claw 6 extends out of the shell 1 and is inserted into the inner hole of the mirror base 14. The other end of the toothed claw 6 is processed with a gear meshing with the driving gear 2, and is rotatably connected to the shell 1 through the rotating shaft 10. The rotation of the driving gear 2 drives the toothed claw 6 to rotate, so that the toothed claw 6 is gradually retracted and inserted into the inner hole of the mirror base 14. The arc-shaped design at both ends of the toothed claw 6 can ensure that the toothed claw 6 is in line contact with the inner hole of the mirror base 14, and realize the processing of the gear.

[0041] The number of the force storage spring 4 is at least one, preferably three, and the three force storage springs 4 are distributed at an angle of 120° in the circumferential direction of the gear pressure ring 3, thereby ensuring that a uniform restoring force is provided to the driving gear 2 without causing redundancy in number.

[0042] The number of the toothed claws 6 is at least two. When the number is two, they are distributed at both radial ends of the driving gear 2 . When the number is more than three, they are evenly distributed along the circumferential direction of the gear pressing ring 3 .

[0043] The housing 1 comprises a shell 1-1, a front cover 1-2 and a rear cover 1-3. The front cover 1-2 and the rear cover 1-3 are respectively fixed on the front and rear sides of the shell 1-1. A through hole is processed on the front cover 1-2 at a position corresponding to the tooling lens 8; a stepped through hole is processed on the rear cover 1-3 at a position corresponding to the tooling lens 8, and the tooling lens 8 is pressed in the stepped through hole by a lens pressing ring 9; an axial hole 1-1-1 is processed on the shell 1-1 at a position corresponding to the tooling lens 8, and the light beam passes through the through hole of the front cover 1-2 and the axial hole 1-1-1 and then is incident on the tooling lens 8. The axial hole 1-1-1 extends axially to form a hollow shaft 1-1-2, and the outer edge of the shell 1-1 extends axially to form an annular wall 1-1-3, and a notch 1-1-4 for the toothed claw 6 to rotate is processed on the annular wall 1-1-3, and a rotating hole 1-1-6 for the movable handle 7 to rotate is also processed on the shell 1-1 and the rear cover 1-3, respectively.

[0044] One end of the annular wall 1-1-3 is inclined inward to form a limit block 1-1-5, which is used to limit the rotation of the toothed claw 6 to avoid excessive rotation of the toothed claw 6 and ensure that the maximum expansion state of the toothed claw 6 is the position where the extension line of the toothed claw 6 passes through the center of the shell 1-1.

[0045] Threaded holes are respectively provided on the end surface of the annular wall 1-1-3 and the shell 1-1. The front cover 1-2 is fixedly connected to the end surface of the annular wall 1-1-3 by screws, and the rear cover 1-3 is fixedly connected to the shell 1-1 by screws.

[0046] The side of the rear cover 1-3 facing the gear pressure ring 3 extends axially to form a circular positioning protrusion 1-3-1, and the inner side of the hollow shaft 1-1-2 extends to form an arc-shaped positioning block 1-1-7. The radial positioning of the rear cover 1-3 and the shell 1-1 is achieved by the cooperation of the arc-shaped positioning block 1-1-7 and the circular positioning protrusion 1-3-1.

[0047] The gear pressing ring 3 is a circular ring structure, and a keyway 3-1 is machined along the axial direction of the gear pressing ring 3. An arc key 13 is fixed to the outer side of the hollow shaft 1-1-2. For the radial direction, the arc key 13 cooperates with the keyway 3-1 to prevent the gear pressing ring 3 from rotating around the hollow shaft 1-1-2. For the axial direction, the gear pressing ring 3 is prevented from axially moving by tightening the front cover 1-2.

[0048] The gear pressure ring 3 extends radially outward to form a pressure block 3-2, the outer side of the driving gear 2 is processed to form a gear, and the inner side of the driving gear 2 extends radially to form an inner edge 2-1. Through the cooperation of the pressure block 3-2 and the inner edge 2-1, the gear pressure ring 3 can axially limit the driving gear 2 to prevent the driving gear 2 from axially moving.

[0049] A cylinder is fixed on the inner edge 2 - 1 , and a cylinder is fixed on the side of the gear pressure ring 3 . One end of the force storage spring 4 is hooked on the cylinder of the inner edge 2 - 1 , and the other end is hooked on the cylinder of the gear pressure ring 3 .

[0050] A cylinder is fixed on the side of the limit block 1-1-5, a cylinder is fixed on the toothed claw 6, one end of the preload spring 5 is hooked on the cylinder of the limit block 1-1-5, and the other end of the preload spring 5 is hooked on the cylinder of the toothed claw 6. The preload spring 5 is used to eliminate the gap caused by the gear meshing error, so as to achieve the purpose of synchronous rotation of multiple toothed claws 6.

[0051] The synchronous angle change of multiple toothed claws 6 can ensure that the center of the lens installation and adjustment multiplexing device 14 always remains at the center of the inner hole of the lens base 15, and the center of the tooling lens 9 is equivalent to the center of the inner hole of the lens base 15. Before and after the outer diameter of the lens installation and adjustment multiplexing device 14 is adjusted, the center of the crosshairs of the tooling lens 8 is coaxial with the center of the circumscribed circle formed by the multiple toothed claws 6, thereby reducing the influence of the coaxial error of the lens installation and adjustment multiplexing device 14 itself on the coaxial installation and adjustment of the lens group.

[0052] The length of the toothed claw 6 can be designed according to the size of the inner diameter of the lens barrel 15. By lengthening the length of the toothed claw 6, the adjustment of the lens barrel with a larger inner diameter can be realized. The toothed claw 6 needs to have a certain thickness to ensure its rigidity, and its end is designed to be in an arc shape so that it always keeps line contact with the inner hole of the lens barrel 15 and keeps the center line parallel to the center line of the lens barrel 15. The toothed claw 6 is made of a wear-resistant material with a high hardness, and the drive gear 2 is made of a wear-resistant material with a small sliding friction coefficient.

[0053] Under the action of the elastic force provided by the force storage spring 4, the toothed claw 6 always keeps a counterclockwise rotation around the rotating shaft 10, ensuring that in the natural state, the envelope cylinder diameter of the lens installation and adjustment multiplexing device 14 is the largest, and by operating the movable handle 7, the toothed claw 6 is rotated clockwise to gradually reduce the envelope cylinder diameter, and by changing the position angle α of the toothed claw 6, the envelope cylinder size of the lens installation and adjustment multiplexing device 14 can be adjusted, that is, it is suitable for lens holders 15 with different inner diameters; after the lens installation and adjustment multiplexing device 14 is placed in the inner hole of the lens holder 15, the movable handle 7 is released, and the force storage spring 4 is used to tend to rotate the toothed claw 6 counterclockwise to expand the envelope cylinder size of the lens installation and adjustment multiplexing device 14, so that the lens installation and adjustment multiplexing device 14 is stuck in the inner hole of the lens holder 15.

[0054] For the convenience of operation, a fixed handle 11 is fixed by screws on the side of the rear cover 1-3 facing away from the shell 1-1 and located near the movable handle 7, so that the staff can hold the fixed handle 11 with one finger and operate the movable handle 7 with the other finger.

[0055] The fixed handle 11 and the movable handle 7 form a pair of handles, and the lens installation and adjustment multiplexing device 14 can be provided with at least one pair of handles.

[0056] The above content describes in detail the structure of the lens adjustment and multiplexing device provided by the present invention. The present invention also provides a lens adjustment method, which is implemented using the above lens adjustment and multiplexing device.

[0057] like Fig. 9 As shown, taking the adjustment of two lenses as an example, the lens adjustment method specifically includes the following steps:

[0058] S1. First, install each tooling lens in the corresponding lens adjustment and multiplexing device 14, then install each lens adjustment and multiplexing device 14 with the tooling lens into the inner hole of the corresponding lens holder 15, and use the device pressing ring 19 to press it tightly.

[0059] The device pressing ring 19 is used to prevent the lens installation and multiplexing device 14 from axially moving in the lens seat 15.

[0060] S2. Arrange the mirror holders 15 in sequence and place them on the mounting surface of the flat bottom plate 17.

[0061] S3. Use the theodolite 18 to check in turn whether the center of the inner hole of each mirror base 15 is parallel to the mounting surface of the plane bottom plate 17. If not, grind the mounting surface of each mirror base 15 until the center of the inner hole of each mirror base 15 is parallel to the mounting surface of the plane bottom plate 17.

[0062] Each mirror base 15 is inspected one by one by the theodolite 18. All the mirror bases 15 can be placed on the mounting surface of the flat bottom plate 17 first, and each mirror base 15 can be inspected by moving the theodolite 18. Alternatively, the theodolite can be set up first, and the mirror base 15 farthest from the theodolite 18 can be placed on the mounting surface of the flat bottom plate 17 for inspection, and then the mirror base 15 farthest from the theodolite 18 can be placed on the mounting surface of the flat bottom plate 17 for inspection, and so on, to complete the inspection of all the mirror bases 15.

[0063] S4. Place the lens holders 15 that have been inspected on the flat bottom plate 17 through the adjustment pads 16, and check whether the center heights of the crosshairs of each tooling lens are consistent through the theodolite 18. If not, grind the thickness of each adjustment pad 16 until the center heights of the crosshairs of each tooling lens are consistent.

[0064] Determine the center height of the crosshairs of the tooling lenses according to the adjustment requirements, and adjust the thickness of the pad 16 by grinding to make the crosshairs of all tooling lenses reach the same center height

[0065] S5. Fix each lens holder and replace each tooling lens with a lens.

[0066] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the disclosure of the present invention can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution disclosed in the present invention can be achieved, and this document does not limit this.

[0067] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
