Description

Technical Field

[0001] This utility model relates to the field of optical instrument processing technology, and in particular to a fixing device for optical instrument processing. Background Technology

[0002] Optical instruments are a very important category in the instrumentation industry. Optical instrument processing is a complex process involving multiple disciplines and fields, mainly including technical steps such as cutting, grinding, polishing, cleaning, coating, assembly (gluing) and testing. The raw material for optical processing is mainly optical glass.

[0003] A search revealed that patent CN221516993U discloses a fixing device for optical instrument processing. This device uses a drive mechanism to control several push tubes to simultaneously approach the center of an operating panel, using these push tubes to press the lens of the optical instrument, thereby fixing the lens to the center of the operating panel surface. However, during use, the push tubes located on the side of the lens can interfere with the cutting equipment's ability to cut the lens side during cutting, requiring avoidance of the push tubes. Secondly, the lens angle cannot be adjusted after fixing, thus hindering cutting convenience. Furthermore, the cutting process generates dust, and this device lacks a dust collection function, thus requiring further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fixing device for optical instrument processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixing device for optical instrument processing, comprising a base plate, a base fixed on the upper surface of the base plate, the base being hollow inside, a vertical shaft rotatably connected through the top wall of the base via a bearing, a support plate fixedly connected to the top of the vertical shaft, a rotary drive assembly for driving the vertical shaft to rotate installed inside the base, a clamping assembly provided directly below the support plate, two second cylinders for driving the clamping assembly to rise and fall fixedly installed on the upper surface of the base, an L-shaped plate fixed on the side of the upper surface of the base plate, a squeezing assembly and a suction assembly fixedly fixed on the top of the L-shaped plate, the squeezing assembly being located directly above the support plate.

[0006] Furthermore, the extrusion assembly includes a third cylinder fixed to the top of the L-shaped plate, and the bottom telescopic end of the third cylinder is rotatably connected to a pressure plate via a bearing.

[0008] Furthermore, the clamping assembly includes a disc located below the support plate, and the disc has a reserved opening in the middle for the vertical shaft to pass through. The disc has three side slots on its side, and the extension line of each side slot passes through the center of the disc. Each side slot has a first cylinder fixed inside it, and the extension end of the first cylinder is fixedly connected to a clamping plate.

[0009] Furthermore, a rubber pad is fixed to the surface of the clamping plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a fixing device for optical instrument processing is disclosed, including a base plate 1, a base 2 fixed on the upper surface of the base plate 1, and the interior of the base 2 is hollow. A vertical shaft 3 is rotatably connected through the top wall of the base 2 via a bearing. A support plate 4 is fixedly connected to the top of the vertical shaft 3. A rotary drive assembly 5 that drives the vertical shaft 3 to rotate is installed inside the base 2. A clamping assembly 6 is provided directly below the support plate 4. Two second cylinders 7 that drive the clamping assembly 6 to lift and lower are fixedly installed on the upper surface of the base 2. An L-shaped plate 8 is fixed on the side of the upper surface of the base plate 1. A squeezing assembly 9 and a suction assembly 10 are fixed on the top of the L-shaped plate 8. The squeezing assembly 9 is located directly above the support plate 4.

[0023] The extrusion assembly 9 includes a third cylinder 91 fixed to the top of the L-shaped plate 8, and a pressure plate 92 is rotatably connected to the bottom telescopic end of the third cylinder 91 via a bearing.

[0024] After the lens of the optical instrument is placed on the surface of the support plate 4, the pressure plate 92 can be lowered by the third cylinder 91, and the lens can be pressed and fixed by the pressure plate 92.

[0025] The rotary drive assembly 5 includes a servo motor 51 fixed inside the base 2 and a worm gear 53 fixed to the bottom surface of the vertical shaft 3. The output shaft of the servo motor 51 is fixedly connected to a worm 52, and the worm 52 meshes with the worm gear 53.

[0026] Under the transmission action of worm gear 52 and worm wheel 53, servo motor 51 can drive vertical shaft 3 to rotate at a certain angle, thereby changing the angle of the lens placed on the upper surface of support plate 4. Furthermore, worm gear 52 and worm wheel 53 have self-locking properties, so the support plate 4 will not rotate when the lens is being cut.

[0027] The clamping assembly 6 includes a disc 61 located below the support plate 4, and a reserved opening 62 for the vertical shaft 3 to pass through the middle of the disc 61. Three side slots 63 are provided on the side of the disc 61, and the extension line of each side slot 63 passes through the center of the disc 61. A first cylinder 64 is fixed inside each side slot 63, and a clamping plate 65 is fixedly connected to the telescopic end of the first cylinder 64.

[0028] By simultaneously shortening the three first cylinders 64, the three clamping plates 65 can be driven to push the lens towards the center of the support plate 4.

[0029] A rubber pad 66 is fixed to the surface of the clamp 65. When the clamp 65 clamps and fixes the lens, the rubber pad 66 can protect the lens.

[0030] The top telescopic ends of the two second cylinders 7 are fixedly connected to the lower surface of the disc 61.

[0031] The extension and retraction of the second cylinder 7 can drive the disc 61 to rise and fall.

[0032] The suction assembly 10 includes a metal rod 101 fixedly connected to the top of the L-shaped plate 8, and a dust collection hood 102 is fixed to the other end of the metal rod 101. A hose 103 is fixed in the middle of the dust collection hood 102 and is connected to the vacuum cleaner.

[0033] Once cutting begins, the vacuum cleaner connected to the hose 103 can be activated, and the dust generated during cutting can be collected using the dust hood 102. The metal rod 101 can be bent, making it easy to move the dust hood 102 as close to the cutting edge as possible to maximize dust collection.

[0034] Working principle: First, place the lens on the upper surface of the support plate 4. Then, activate the three first cylinders 64 on the side of the disc 61 to shorten simultaneously, thereby moving the three clamping plates 65. The three clamping plates 65 clamp the lens to the center position of the upper surface of the support plate 4. Then, activate the third cylinder 91 to drive the pressure plate 92 to descend and press and fix the lens. Next, the first cylinder 64 drives the clamping plate 65 to return to its original position away from the lens. Then, activate the second cylinder 7 to drive the disc 61 to descend, so that the clamping plate 65 is away from the side of the lens. At this time, the side of the lens can be cut by the cutting device. During the cutting of the lens, the support plate 4 and the lens can be rotated by the servo motor 51, which provides greater flexibility for the cutting. After the cutting is completed, activate the third cylinder 91 to drive the pressure plate 92 to return to its original position. Finally, the lens can be removed.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
