[0002] During the polishing process of optical glass lenses, a fixed fixture is needed to stably clamp the lenses to ensure polishing accuracy and surface quality. The clamping stability, adjustment flexibility, and lens protection capabilities of the fixed fixture are key factors affecting processing efficiency and product quality, and directly relate to the compliance rate of core indicators such as lens surface smoothness and flatness.

[0003] Traditional lens fixing fixtures mostly use rigid clamping structures, which can easily lead to scratches or stress damage on the lens surface. At the same time, the position and height adjustment mechanisms of existing fixtures are complicated to operate, making it difficult to quickly adapt to lenses of different sizes and thicknesses. They also lack effective preliminary positioning functions, resulting in low clamping efficiency and affecting the continuity of processing and the needs of automated production.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, an optical glass lens polishing and fixing fixture is provided.

[0026] like Figure 1-6 As shown, the optical glass lens polishing and fixing fixture according to an embodiment of the present invention includes an adjustment structure 1, a lifting structure 2 installed on the adjustment structure 1, a fixing structure 3 and an adsorption structure 5 connected to the lifting structure 2, and an optical lens 4 fixed on the fixing structure 3 and the adsorption structure 5. The adjustment structure 1 realizes the function of adjusting the position of the lifting structure 2, the lifting structure 2 realizes the function of adjusting the height of the fixing structure 3 and the adsorption structure 5, the adsorption structure 5 realizes the function of adsorption and positioning of the optical lens 4, and the fixing structure 3 realizes the function of fixing the optical lens 4.

[0027] The adjustment structure 1 includes a fixed plate 101, a guide rail 102, an adjusting block 103, a mounting bracket 104, a fitting groove 105, a connecting seat 106, a threaded groove 107, an adjusting threaded rod 108, a hexagonal groove 109, and a throttle 110. The fixed plate 101 has a guide rail 102, and the adjusting block 103 is slidably connected within the guide rail 102. The mounting bracket 104 is fixedly installed on the fixed plate 101. Fitting grooves 105 are provided on both sides of the adjusting block 103. The adjusting block 103 is slidably connected to the guide rail 102 through the fitting groove 105. The adjusting block 103 is fixedly provided with a connecting seat 106. The bottom end of the adjusting block 103 is provided with a threaded groove 107. The threaded groove 107 is connected to the adjusting threaded rod 108. The adjusting threaded rod 108 is rotatably connected to the guide rail 102 of the fixed plate 101. A hexagonal groove 109 is provided on one side of the adjusting threaded rod 108. The hexagonal groove 109 fits the throttle 110.

[0028] The adjustment structure 1 is the core of the entire tooling for position adjustment. Through the coordinated operation of multiple components, it achieves horizontal position adjustment of the lifting structure 2 to accommodate the clamping and disassembly of the optical lens 4. Its base component, the fixing plate 101, provides the mounting platform, and the guide rail 102 provides a guiding path for the sliding of the adjustment block 103. The adjustment block 103 is limited and slides within the guide rail 102 via the mating grooves 105 on both sides, ensuring stable movement. The connecting seat 106 at the top of the adjustment block 103 is directly connected to the first lifting rod 201 and the second lifting rod 202 in the lifting structure 2, and the threaded groove 107 at the bottom connects to the adjustment... The threaded rod 108 is engaged in transmission. When the throttle 110 is inserted into the hexagonal groove 109 of the threaded rod 108 and rotated, the threaded rod 108 drives the adjusting block 103 to slide along the guide rail 102, thereby driving the connecting seat 106 and its lifting rod to move, realizing the position adjustment of the fixed structure 3. At the same time, the mounting bracket 104 on the fixed plate 101 fixes the third lifting rod 203 of the lifting structure 2, forming a reference point for position adjustment. Through this structure, the relative position of the fixed structure 3 and the adsorption structure 5 can be flexibly adjusted, which facilitates the clamping operation of the optical lens 4 and subsequent disassembly.

[0029] The lifting structure 2 includes a first lifting rod 201, a second lifting rod 202, and a third lifting rod 203. The second lifting rod 202 is provided on one side of the first lifting rod 201. The first lifting rod 201 and the second lifting rod 202 are symmetrically installed on the connecting seat 106. The third lifting rod 203 is fixedly installed on the mounting support 104. The lifting rods are electric lifting rods.

[0030] The lifting structure 2 is responsible for height adjustment. It drives the fixed structure 3 and the adsorption structure 5 to rise and fall through three sets of lifting rods to accommodate the fixing requirements of optical lenses 4 of different thicknesses. The first lifting rod 201 and the second lifting rod 202 are symmetrically installed on the connecting seat 106 of the adjusting structure 1 and move synchronously with the adjusting block 103. Their driving rods are directly connected to the mounting block 301 of the fixed structure 3. Through the lifting action, the plastic ball 302 of the fixed structure 3 moves up and down, realizing the flexible clamping height adjustment of the optical lens 4. The third lifting rod 203 is fixedly installed on the mounting support 104 of the adjusting structure 1 and its position remains fixed. Its driving rod is connected to the docking base 501 of the adsorption structure 5. Through the lifting action, the height of the suction cup 505 of the adsorption structure 5 is adjusted to ensure that the suction cup 505 is in close contact with the surface of the optical lens 4. The three sets of lifting rods are independently adjustable and can respectively adapt to the height requirements of the fixed structure 3 and the adsorption structure 5, improving the compatibility with lenses of different thicknesses.

[0031] The fixing structure 3 includes a mounting block 301 and a plastic ball 302. One end of the mounting block 301 is fixedly connected to the plastic ball 302. The mounting block 301 is fixedly installed on the drive rods of the first lifting rod 201 and the second lifting rod 202 respectively.

[0032] The fixing structure 3 is a flexible clamping component for the optical lens 4. It achieves stable fixation of the lens through linkage with the lifting structure 2. Its core component, the mounting block 301, is fixed to the drive rods of the first lifting rod 201 and the second lifting rod 202 in the lifting structure 2, and moves up and down synchronously with the lifting rods. The plastic ball 302 at one end of the mounting block 301 directly contacts the optical lens 4, using the elasticity and friction of the plastic material to achieve "flexible clamping" and avoid rigid contact causing scratches or indentations on the lens surface. When the first and second lifting rods drive the mounting block 301 to move up and down, the plastic ball 302 applies clamping force from both sides or the top and bottom of the lens. Together with the adsorption positioning of the adsorption structure 5, it ensures the stability of the optical lens 4 during the polishing process. At the same time, the lifting adjustment can adapt to the clamping requirements of lenses of different thicknesses.

[0033] The adsorption structure 5 includes a docking base 501, a fixing ring 502, a connecting rod 503, a pressure regulating cylinder 504, a suction cup 505, a fixing seat 506, a piston ring 507, a transmission block 508, a transmission rod 509, a guide rod 510, a transmission threaded rod 511, a threaded block 512, a gear ring 513, a gear 514, a drive motor 515, and a rotating support 516. The docking base 501 is fixedly installed on the drive rod of the third lifting rod 203. The docking base 501 is fixedly connected to the fixing ring 502. The bottom end of the fixing ring 502 is fixedly connected to the connecting rod 503. The fixing ring 502 is fixedly connected to the pressure regulating cylinder 504 through the connecting rod 503. One end of the pressure regulating cylinder 504 is fixedly provided with a fixing seat 506. The fixing seat 506 is connected to the suction cup 505. The inner ring of the fixing seat 506 is provided with a limit. The groove and the limiting groove are provided with piston ring 507. One end of piston ring 507 is flatly embedded with transmission block 508. Transmission block 508 is fixedly connected to transmission rod 509. Transmission rod 509 is fixedly provided with guide rod 510. Guide rod 510 is slidably connected to guide block in fixed ring 502. Transmission thread rod 511 is fixedly connected to guide rod 510. Transmission thread rod 511 is drivenly connected to threaded block 512. Threaded block 512 is fixedly connected to gear ring 513. Gear ring 513 meshes with gear 514. Gear 514 is connected to drive motor 515. Drive shaft of drive motor 515 is connected to gear 514. Drive motor 515 is symmetrically installed on both sides of fixed ring 502. Rotary support 516 is fixedly installed on fixed ring 502. Rotary support 516 is rotatably connected to gear ring 513.

[0034] The adsorption structure 5 is the initial positioning core of the optical lens 4. It achieves precise positioning and convenient disassembly of the lens through negative pressure adsorption and rapid pressure release. Its basic component, the docking base 501, is connected to the third lifting rod 203 drive rod of the lifting structure 2, and its height is adjusted with the lifting rod. The fixing ring 502 fixes the pressure regulating cylinder 504 through the connecting rod 503. The fixing seat 506 at the end of the pressure regulating cylinder 504 is connected to the suction cup 505, forming the adsorption execution end. The drive motor 515 drives the gear ring 513 to rotate through the gear 514. The gear ring 513 drives the threaded block 512 and the transmission threaded rod 511 to rotate. Under the limit of the guide rod 510, the transmission threaded rod 511 pushes the transmission rod 509 and the piston ring 507 to slide inside the pressure regulating cylinder 504. At this time, the transmission... Block 508 is flatly embedded in the bottom surface of piston ring 507, sealing the space formed by the contact between suction cup 505 and lens. The sliding of piston ring 507 changes the pressure in the sealed space, generating negative pressure to achieve adsorption and positioning. In reverse drive, transmission rod 509 drives transmission block 508 to move away from lens. When piston ring 507 is blocked by the limiting groove of fixed seat 506, transmission block 508 disengages from piston ring 507. The sealed space is connected to the other end of pressure regulating cylinder 504 through the gap between transmission rod 509 and piston ring 507 and the misalignment space between transmission block 508 and piston ring 507. The negative pressure disappears, suction cup 505 releases lens, facilitating disassembly. This structure achieves precise control of negative pressure through mechanical transmission, improving the stability of adsorption and positioning and the convenience of disassembly.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] The optical lens 4 can be flexibly clamped and fixed by the plastic ball 302 of the fixing structure 3 connected to the first lifting rod 201 and the second lifting rod 202. The adjustment structure 1 can rotate the adjusting threaded rod 108 in different positions by the throttle 110, so that the adjusting threaded rod 108 can adjust the position of the first lifting rod 201 and the second lifting rod 202 on the connecting seat 106 through the transmission with the thread groove 107 of the adjusting block 103, thereby making it easier to clamp the optical lens 4. After releasing the clamp, the lifting rod can adjust the height of the plastic ball 302 of the fixing structure 3 and the adsorption structure 5 respectively, to adapt to the clamping and fixing requirements of optical lenses 4 of different thicknesses. The drive motor 515 of the adsorption structure 5 can drive the gear ring 513 and the threaded block 512 to rotate through the gear 514. In turn, the threaded block 512 drives the transmission rod 509 to adjust its horizontal height under the restriction of the guide rod 510, which in turn drives the transmission rod 509 and the piston ring 507 to slide and adjust within the pressure regulating cylinder 504. The transmission block 508... Under normal conditions, under the tension of the return spring, the piston ring 507 is flatly embedded in the bottom surface of the piston ring 507. This creates a sealed space after the piston ring 507 contacts the surface of the optical lens 4 using the suction cup 505. The piston ring 507 then slides within the pressure regulating cylinder 504, changing the pressure within the sealed space and creating a negative pressure relative to the outside. This allows the suction cup 505 to adhere to the optical lens 4, providing initial positioning. Conversely, when the transmission rod 509 continuously drives the transmission block 508 towards the optical lens 4, the piston ring 507 remains flat. The reverse transmission of piston ring 507 eventually causes piston ring 507 to be limited by the limiting groove, causing its transmission block 508 to disengage from piston ring 507. This allows the sealed space of its suction cup 505 to connect with the space at the other end of piston ring 507 through the gap between transmission rod 509 and the inner ring of piston ring 507, as well as the space where transmission block 508 and piston ring 507 are misaligned. Since the other half of the space between piston ring 507 and pressure regulating cylinder 504 is provided with a vent hole connecting to the outside, its suction cup 505 loses its negative pressure state, which facilitates the disassembly of optical lens 4.
