Description

Technical Field

[0001] The present invention relates to a device and method for disassembling optical machine parts, and in particular to a device and method for disassembling large-caliber optical machine parts after gluing. Background Art

[0002] In optical systems, gluing is the most important method of connecting optomechanical parts. If the performance of optomechanical parts after gluing does not meet the requirements, the parts must be disassembled. Small-diameter optomechanical parts are lightweight and easy to disassemble after soaking in ether solution. However, large-diameter optomechanical parts (diameter D greater than 400mm) are heavy and require much more glue during gluing than small-diameter parts. Even after soaking in ether or gasoline, they are still difficult to disassemble. Furthermore, when the circumferential gap between optomechanical parts is less than 0.1mm, the glue layer is not easy to cut. This makes disassembly of optomechanical parts particularly difficult and risky. Summary of the Invention

[0003] In order to solve the technical problems in the prior art of gluing and disassembling large-caliber optomechanical parts, that is, it is still difficult to disassemble after soaking in ether or gasoline, and when the circumferential gap between the optomechanical parts is less than 0.1 mm, the adhesive layer is not easy to cut, resulting in the optomechanical parts being particularly difficult to disassemble and having greater risks, the present invention provides a device and method for disassembling large-caliber optomechanical parts after gluing.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] The present invention provides a device for disassembling large-aperture optical mechanical parts after gluing. The large-aperture optical mechanical parts include a mirror frame and a mirror glued in the mirror frame. The device is special in that it includes an optical platform and a first supporting assembly, a second supporting assembly, an adapter plate, a pressing assembly, and a monitoring assembly arranged on the optical platform.

[0006] The first supporting assembly is a compressible supporting assembly, which is used to be arranged at the bottom of the frame to be disassembled to support the frame to be disassembled;

[0007] The second supporting assembly is used to be arranged at the bottom of the mirror to be disassembled to support the mirror to be disassembled;

[0008] The adapter plate is used to be placed on the top of the frame to be disassembled, and its bottom surface contacts the top surface of the frame to be disassembled;

[0009] The pressing end of the pressing assembly is arranged on the adapter plate and is used to press down the frame to be disassembled;

[0010] The monitoring component is used to monitor the downward pressure of the adapter plate to ensure that the downward pressure around the adapter plate is consistent.

[0011] Furthermore, the first support assembly includes N two-dimensional lifting frames, where N is greater than or equal to 3;

[0012] The N two-dimensional lifting frames are evenly arranged around the circumference of the frame to be disassembled, and the active end of each two-dimensional lifting frame contacts the bottom surface of the frame to be disassembled.

[0013] Furthermore, the second support assembly includes M mirror support fixtures, where M is greater than or equal to 3;

[0014] The M mirror support fixtures are evenly arranged along the circumference at the bottom of the mirror to be removed, with the axis of the mirror to be removed as the center line.

[0015] Furthermore, the pressing assembly includes K threaded rods and nuts respectively sleeved on each threaded rod, where K is greater than or equal to 3;

[0016] The K threaded rods are vertically and evenly slidably arranged on the adapter plate around the circumference, and the bottom of each threaded rod is fixed;

[0017] The nut is located on the top of the adapter plate, and the bottom surface of the nut contacts the top surface of the adapter plate.

[0018] Furthermore, the monitoring assembly includes L magnetic meter bases and a dial indicator provided on each magnetic meter base, and L is greater than or equal to 3;

[0019] The L magnetic meter bases are evenly distributed around the adapter plate in the circumferential direction;

[0020] The needle of the dial indicator is perpendicular to the top surface of the adapter plate.

[0021] Furthermore, the M mirror support fixtures are circular cylindrical structures made of nylon or polytetrafluoroethylene, and the heights of the M mirror support fixtures are the same, which is greater than the sum of the depth of the mirror frame to be removed and half the height of the mirror to be removed.

[0022] Further, a feeler gauge is included;

[0023] The feeler gauge is used to measure whether there is any tilt between the mirror frame to be disassembled and the mirror to be disassembled during the disassembly process;

[0024] Said N=M=K=L=3.

[0025] Furthermore, the adapter plate includes a large adapter ring and a small adapter ring coaxially arranged at the bottom of the large adapter ring;

[0026] The bottom surface of the small adapter ring contacts the top surface of the mirror frame to be disassembled, and the inner diameter of the small adapter ring is larger than the diameter of the mirror to be disassembled and smaller than the outer diameter of the mirror frame to be disassembled;

[0027] The pressing assembly is arranged on the large adapter ring;

[0028] The monitoring component is used to monitor the downward pressure of the large adapter ring.

[0029] The present invention also provides a method for disassembling large-caliber optical machine parts after gluing, which is special in that it includes the following steps:

[0030] Step 1: Build the above-mentioned disassembly device for large-caliber optical machine parts after gluing at the corresponding positions of the mirror frame and the mirror to be disassembled after gluing;

[0034] Step 5. Based on the monitoring of the monitoring component, the adapter plate is gradually pressed down to a preset height through the pressing component, and the frame to be disassembled and the first supporting component are pressed down to corresponding heights in turn. The second supporting component supports the mirror to be disassembled until the glue between the frame to be disassembled and the mirror to be disassembled is removed, completing the disassembly between the frame and the mirror of the large-aperture optical machine parts.

[0035] Furthermore, step 5 is specifically as follows:

[0036] 5.1. Observe the monitoring displays of L dial indicators and simultaneously rotate K nuts, so that each of the L dial indicators rotates 0.05 mm. The adapter plate, the mirror frame to be disassembled, and the N two-dimensional lifting frames are then pressed down by the K nuts in sequence to the corresponding heights. At the same time, the M mirror support fixtures are supported on the bottom of the mirror to be disassembled, keeping the mirror in place.

[0037] 5.2. Use a feeler gauge to measure the gap between the mirror frame and the mirror to be removed to determine whether the mirror frame and the mirror to be removed are tilted relative to each other:

[0038] If there is no tilt, proceed to step 5.3;

[0039] If there is any tilt, rotate the corresponding nuts to make sure there is no tilt between the mirror frame and the mirror to be removed, and then proceed to step 5.3;

[0040] 5.3. Repeat steps 5.1 to 5.2 until the glue between the frame and the mirror to be disassembled is removed, completing the disassembly of the frame and the mirror of the large-aperture optical machine part.

[0064] Step 4: Place three magnetic gauge holders 9 and three dial indicators 10 on the circumference of the adapter plate 6, with the needles of the three dial indicators 10 perpendicular to the top surface of the large adapter ring 61, to monitor the downward pressure of the adapter plate 6;

[0065] Step 5: Based on the monitoring of the monitoring component, the adapter plate 6 is gradually pressed down by the pressing component to a preset height, and the frame 1 to be disassembled and the first support component are pressed down by the pressing component to a corresponding height in turn, and the second support component supports the mirror 2 to be disassembled until the adhesive between the frame 1 to be disassembled and the mirror 2 to be disassembled is detached. Specifically comprising:

[0066] 5.1. Observe the monitoring displays of the three dial indicators 10 and simultaneously rotate the three nuts 8 so that each of the three dial indicators 10 rotates 0.05 mm. The adapter plate 6, the mirror frame 1 to be disassembled, and the three two-dimensional lifting frames 3 are then pressed down by the three nuts 8 to the corresponding heights.

When the adhesive between the frame 1 and the mirror 2 to be disassembled is completely removed, the magnetic base 9, dial indicator 10, threaded rod 7, adapter plate 6, etc. are removed in sequence to complete the entire disassembly process.
