[0002] With the development of laser technology, in order to achieve the goals of high power and small far-field spot for chemical, solid-state, fiber lasers, etc., most of them choose large-aperture beam transmission. The apertures of window mirrors, beam splitters, reflectors, etc. in the transmission channel are up to several hundred millimeters, and the weight reaches more than a dozen kilograms. Moreover, due to the special film system, their prices are quite high. For a long time, the disassembly and assembly of the above-mentioned large-aperture optical mirrors have always been a technical problem. The fixture for taking optical lenses is disclosed in Patent Application No.: 200810302312.2, and an optical lens disassembly device is disclosed in Patent Application No.: 201410064862.0. The above-disclosed optical lens disassembly devices are for small-aperture lens modules or optical lenses, etc., and cannot complete the disassembly, installation, and mounting of large-aperture optical mirrors. In the past, for the disassembly and assembly of large-aperture optical mirrors, most of them required special technicians and the cooperation of multiple people to complete, and the optical mirror film system and mirror surface were sometimes damaged during the disassembly and assembly process. In today's rapidly developing laser field, the above disassembly and assembly technologies and methods obviously can no longer meet the current requirements, and the disassembly and assembly technologies and devices for large-aperture optical mirrors need to be developed urgently. Summary of the Invention

[0003] The invention purpose of the present invention is: aiming at the above problems, to provide an auxiliary device for installing and removing a large-aperture optical mirror, which can effectively prevent damage during the installation and removal of the large-aperture optical mirror and greatly improve the disassembly and assembly efficiency.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An auxiliary device for installing and removing a large-aperture optical mirror includes a support assembly, which includes a tabletop and support legs arranged under the tabletop, and a lifting hole is arranged in the middle of the tabletop;

[0006] A tray, which is arranged at the lifting hole;

[0007] A lifting frame, which is located below the lifting hole and connected to the tabletop;

[0008] A screw jack, which is arranged on the lifting frame and connected to the tray to drive the tray to lift and lower;

[0009] A clamping assembly, which includes a plurality of clamping devices arranged on the tabletop. The clamping device includes a connecting rod, one end of the connecting rod is connected to the tabletop, and a clamping rod for adjusting the up and down height by being threadedly connected is arranged at the opposite end.

[0010] In the present invention, the support assembly plays a supporting role and is used for placing the frame of a large-diameter optical mirror; the screw jack is used to drive the tray to lift during the installation and removal of the large-diameter optical mirror. The tray can place the large-diameter optical mirror, and the lifting height is used to install or remove the large-diameter optical mirror. Among them, the screw jack is a simple and convenient lifting mechanism, which is convenient to control the lifting position; the clamping assembly is used to clamp and fix the frame of the large-diameter optical mirror. The clamping rod is threadedly connected to the connecting rod, and the clamping rod adjusts the height up and down through the thread. During use, the height is adjusted so that the clamping rod presses the frame to complete its fixation.

[0011] When using the present invention to install a large-diameter optical mirror, first place the frame on the tabletop, then press and fix the frame through the clamping assembly, operate the screw jack to drive the tray to move upward. After reaching the specified mirror installation position, place the large-diameter optical mirror on the tray, and operate the screw jack to drive the tray to move downward until the large-diameter optical mirror is completely installed in the frame, and then fix the large-diameter optical mirror and the frame.

[0012] When using the present invention to remove the large-diameter optical mirror, first place the large-diameter optical mirror and the frame on the tabletop, then press and fix the frame through the clamping assembly, operate the screw jack to drive the tray to move upward. After reaching the mirror removal position, remove the large-diameter optical mirror from the frame.

[0013] Preferably, the screw jack includes a worm, a screw rod and a flange. The flange is connected to the tray, and the worm is connected to the transmission rod.

[0014] In the above solution, the screw jack is a prior art, such as Chinese Patent Applications 201921654482.7, 201920480476.8, etc. By horizontally connecting the transmission rod and the worm, the screw in the jack can be lifted on the side, which is more convenient to operate and avoids the inconvenient operation of using a screw nut or other lifting mechanisms. The flange can make the tray more stable during the lifting process.

[0015] Preferably, a limit block is provided at the end of the screw rod.

[0016] In the above solution, setting the limit block can prevent the guide rod from completely extending out of the guide rod bushing.

[0017] Preferably, the transmission rod passes through a vertical bearing, and the vertical bearing is connected to the tabletop through a connecting block.

[0018] In the above solution, setting the vertical bearing plays a role in supporting the transmission rod, and at the same time, the vertical bearing does not affect the rotation of the transmission rod to drive the screw rod to lift.

[0019] Preferably, a handwheel is provided at the end of the transmission rod.

[0020] In the above solution, a handwheel is provided to facilitate the rotation of the lead screw, and a handwheel handle is provided on the handwheel to facilitate the rotation of the handwheel by shaking.

[0021] Preferably, the transmission rod is connected to the worm through a coupling.

[0022] In the above solution, setting the coupling can play a role in extending the worm.

[0023] Preferably, a transition plate is provided between the tray and the screw jack.

[0024] In the above solution, the tray is made of a flexible material, which can avoid scratching the large-diameter optical mirror. However, the rigidity of the flexible material is insufficient. Setting a transition plate made of a rigid material can protect the tray and support the large-diameter optical mirror. The material of the tray is polytetrafluoroethylene, and the material of the transition plate is steel.

[0025] Preferably, a plurality of guide rod bushings are provided on the lifting frame, the guide rod passes through the guide rod bushings, and is connected to the tray through a guide rod fixing seat.

[0026] Preferably, the guide rods are evenly distributed under the tray.

[0027] In the above solution, setting the guide rod and the guide rod bushing can perform axial limitation during the lifting and lowering of the tray, so that the tray can only move up and down, avoiding possible rotation or shaking during the lifting and lowering of the tray; the guide rod fixing seat makes the connection more stable, and the guide rod fixing seat is fixed on the tray. The number of guide rods is greater than 2, and the number can be set as required.

[0028] Preferably, a plurality of sets of distance-adjusting screw holes are provided on the tabletop centered on the lifting hole, and the plurality of sets of distance-adjusting screw holes are evenly distributed on the tabletop. The connecting rod is threadedly connected to the tabletop through the distance-adjusting screw holes.

[0029] Preferably, the number of sets of distance-adjusting screw holes is the same as the number of clamping devices.

[0030] Preferably, four sets of distance-adjusting screw holes are provided on the tabletop centered on the lifting hole, and two adjacent sets of distance-adjusting screw holes are perpendicular to each other. The connecting rod is threadedly connected to the tabletop through the distance-adjusting screw holes.

[0031] In the above solution, each set of distance-adjusting screw holes includes a plurality of distance-adjusting screw holes. The fixing rod can pass through the connecting rod and be threadedly connected to the distance-adjusting screw holes and fixed on the tabletop. At the same time, the extension line of each set of distance-adjusting screw holes passes through the center of the lifting hole, so that the position of the connecting rod can be adjusted as required to meet different sizes of spectacle frames.

[0032] Preferably, a plurality of sets of leveling screw holes are provided on the tabletop centered on the lifting hole, and the plurality of sets of leveling screw holes are evenly distributed on the tabletop. The leveling rod is threadedly connected to the tabletop from bottom to top through the leveling screw holes.

[0033] Preferably, four groups of leveling screw holes are arranged on the tabletop with the lifting hole as the center. Two adjacent groups of leveling screw holes are perpendicular to each other. The leveling rod is threadedly connected to the tabletop from bottom to top through the leveling screw holes.

[0034] In the above solution, each group of leveling screw holes includes multiple leveling screw holes. When the spectacle frame is not horizontal, the axis of the spectacle frame can be adjusted by adjusting the length of the leveling rod passing through the tabletop, so that the axis of the spectacle frame is consistent with the axis of the screw jack. Of course, the axis can also be made consistent by placing a backing plate under the spectacle frame. A spirit level can be used to confirm whether the mirror surface that should be horizontal is horizontal.

[0035] Preferably, wire screw inserts are arranged in the distance-adjusting screw holes and the leveling screw holes.

[0036] In the above solution, the tabletop can be made of lightweight plates (such as aluminum plates, non-metal plates), and the threads on the lightweight plates are easily damaged, reducing the service life of the device. Setting wire screw inserts can improve the service life of the device.

[0037] Preferably, the connecting rod is L-shaped.

[0038] In the above solution, the fixing rod is threadedly connected to the tabletop through the short rod passing through the L-shaped connecting rod. The L-shaped connecting rod can make the connecting rod have a certain height.

[0039] Preferably, the leveling rod, the clamping rod, and the fixing rod are all toggle screws.

[0040] In the above solution, the position of the toggle screw can be conveniently adjusted by hand.

[0041] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0042] 1. By the upward or downward movement of the lifting mechanism along the axis, the large-aperture optical mirror is taken out of or inserted into the spectacle frame. And through the limitation of the guide rod, the tray in contact with the mirror surface only moves axially without rotating, avoiding damage to the mirror surface during the disassembly and assembly process;

[0043] 2. Equipped with a clamping assembly, through the pressing of the toggle screws arranged above and below the tabletop, the leveling and fixing of the large-aperture optical mirror are realized, ensuring the consistency of the axis of the spectacle frame and the axis of the lifting mechanism during the disassembly and assembly of the large-aperture optical mirror;

[0044] 3. The disassembly and assembly of the large-aperture optical mirror do not require special technicians and the cooperation of multiple people. After general personnel are trained, the reliable disassembly and assembly of the large-aperture optical mirror can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
