[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution: an auxiliary device for polishing machine for optical lens production, including a work cabinet 1, a cabinet door 2 installed on the surface of the work cabinet 1, a foot support 3 installed at the bottom of the work cabinet 1, a worktable 4 connected to the top of the work cabinet 1, a support 5 connected to the top of the worktable 4, a lifting mechanism 6 provided on the surface of the support 5, a moving mechanism 7 provided on the top of the worktable 4, and a lens clamping assembly 8 provided on the surface of the moving mechanism 7.
[0022] The lens clamping assembly 8 includes a base 801, which is positioned above the moving mechanism 7. A fixed base 802 is connected to one upper end of the base 801. A guide groove 803 is formed on the surface of the base 801. A hydraulic cylinder 804 is connected to one side of the base 801. A hydraulic rod 805 is connected to the output end of the hydraulic cylinder 804. An extension rod 806 is connected to one end of the hydraulic rod 805. A movable base 807 is connected to one end of the extension rod 806. A guide block 808 is connected to the bottom of the movable base 807. A rotary motor 809 is connected to the top of both the fixed base 802 and the movable base 807. A rotating disk 810 is connected to the output end of the rotary motor 809. A telescopic tube 811 is connected to the surface of the rotating disk 810. The shrink tube 811 has a limiting groove 812 inside, and a limiting plate 813 is slidably connected inside the limiting groove 812. One end of the limiting plate 813 is connected to a connecting rod 814, and a spring 815 is wound around the outside of the connecting rod 814. One end of the connecting rod 814 and the spring 815 are both connected to a connecting block 816, and one end of the connecting block 816 is connected to a suction cup 817. With the lens clamping assembly 8 in place, when it is necessary to clamp an optical lens, the relevant components of the lens clamping assembly 8 are activated. First, the hydraulic cylinder 804 starts working, and its output end pushes the hydraulic rod 805 to extend, driving the extension rod 806 and the moving seat 807 to move along the guide groove 803 on the surface of the base 801. The guide block 808 and the guide groove 803... The two work together to ensure the stability and linearity of the moving base 807 during movement. This allows for adjustment of the distance between the fixed base 802 and the moving base 807 according to the size of the lens, accommodating optical lenses of different sizes. After the distance is adjusted, the rotary motor 809 above the fixed base 802 and the moving base 807 is activated, driving the rotating disk 810 to rotate and aligning the telescopic tube 811 with the lens position. At this point, the suction cup 817 is pressed to contact the lens surface. During the pressing process, the connecting rod 814 slides in the limiting groove 812 within the telescopic tube 811, compressing the spring 815 to retract it. The limiting plate 813 moves within the limiting groove 812, ensuring the stability of the connecting rod 814's movement. When the suction cup 817 is firmly in contact with the lens... After the lenses are tightly fitted, the pressure is released, and the spring 815 returns to its original shape. The connecting rod 814 drives the connecting block 816, causing the suction cup 817 to firmly adhere to the lens, thus achieving a stable clamping of the lens. During the polishing process, the rotary motor 809 can drive the lens to rotate, so as to polish all parts of the lens evenly. If it is necessary to adjust the lens angle or position, the lens clamping assembly 8 can be moved as a whole through the moving mechanism 7, or the height can be adjusted in conjunction with the lifting mechanism 6 to meet different polishing needs. After polishing is completed, the suction cup 817 is pressed again, the spring 815 is compressed, and the suction cup 817 separates from the lens. Then, the hydraulic cylinder 804 retracts the hydraulic rod 805, driving the moving seat 807 to reset, making it easy to remove the lens.
[0023] Furthermore, four identical sets of foot supports 3 are installed at the bottom of the work cabinet 1, symmetrically distributed at the four corners of the bottom of the work cabinet 1 along the central axis of the work cabinet 1. The foot supports 3 form a stable and reliable support structure. The four sets of symmetrically distributed foot supports can evenly bear the weight of the work cabinet 1 and the equipment above it, ensuring that the polishing machine remains horizontal and stable during operation, avoiding shaking or tilting caused by uneven force, and preventing the work cabinet 1 from directly contacting the ground and causing wear, thus extending the service life of the equipment and providing a stable base environment for high-precision polishing of optical lenses.
[0024] Furthermore, the lifting mechanism 6 includes a lifting motor 601, which is installed at one end of the support 5. The output end of the lifting motor 601 is connected to a threaded rod 602, and the other end of the support 5 is connected to an auxiliary rod 603. The surfaces of the threaded rod 602 and the auxiliary rod 603 are both connected to a first lifting block 604, and the surface of the first lifting block 604 is connected to a connecting seat 605. The inner side of the support 5 is provided with a lifting groove 606, and the inner side of the connecting seat 605 is connected to a second lifting block 607. The surface of the connecting seat 605 is connected to a mounting plate 608, and a grinding disc rotation motor 609 is installed above the mounting plate 608. The output end of the grinding disc rotation motor 609 is connected to a polishing grinding disc 610. Through the setting of the lifting mechanism 6, a stable and reliable support structure is constructed. The four sets of symmetrically distributed feet can evenly bear the weight of the work cabinet 1 and the equipment above, ensuring that the polishing machine remains horizontal and stable during operation and avoiding shaking or tilting due to uneven force.
[0025] Furthermore, under the action of the threaded rod 602, the first lifting block 604 drives the connecting seat 605 to slide inside the lifting groove 606 via the second lifting block 607. The outer wall dimension of the second lifting block 607 matches the inner wall dimension of the lifting groove 606. Through the setting of the lifting groove 606 and the second lifting block 607, a high-precision, low-shake vertical guide system is constructed. The two adopt a precision clearance fit, and the second lifting block 607 fits tightly with the inner wall of the lifting groove 606, effectively limiting the lateral displacement and deflection of the connecting seat 605 during the lifting process. This ensures that the polishing disc 610 rises and falls smoothly in the vertical direction, avoiding a decrease in polishing accuracy due to shaking. At the same time, this structural design forms a stable three-dimensional constraint, which can withstand the vibration and impact generated during polishing operations, preventing parts from loosening. Its dustproof design can also reduce the entry of external impurities, reduce mechanical wear, and ensure the long-term stable operation of the lifting mechanism, providing a reliable height adjustment guarantee for the high-precision polishing of optical lenses.
[0026] Furthermore, the moving mechanism 7 includes a fixed plate 701, which is fixedly connected above the worktable 4. One end of the fixed plate 701 is connected to a moving motor 702, and the output end of the moving motor 702 is connected to a lead screw 703. A lead screw slider 704 is connected to the surface of the lead screw 703. Moving slide rails 705 are connected to both sides of the upper part of the fixed plate 701, and moving sliders 706 are connected to the surface of the moving slide rails 705. A base 801 is fixedly connected above the lead screw slider 704 and the moving slider 706. The moving mechanism... In setting 7, when the height of the polishing disc 610 needs to be adjusted, the lifting motor 601 is started. After the lifting motor 601 is powered on, its output end drives the threaded rod 602 to start rotating. Since the first lifting block 604 is threadedly connected to the threaded rod 602 and is also sleeved on the auxiliary rod 603, the auxiliary rod 603 acts as a guide, restricting the rotational freedom of the first lifting block 604. This allows the first lifting block 604 to slide up and down in the lifting groove 606 only along the axial direction of the threaded rod 602 and the auxiliary rod 603. During the movement of block 604, it drives the connecting seat 605 to move synchronously. The second lifting block 607 on the inner side of the connecting seat 605 cooperates with the lifting groove 606 on the inner side of the bracket 5 to further enhance the stability of the connecting seat 605 during movement and prevent it from shifting or shaking during the lifting process. The connecting seat 605 drives the mounting plate 608 to rise and fall. The grinding disc rotation motor 609 and the polishing grinding disc 610 above the mounting plate 608 also rise or fall accordingly, thereby precisely adjusting the distance between the polishing grinding disc 610 and the optical lens to adapt to lenses of different thicknesses and different polishing process requirements. When the polishing grinding disc 610 reaches the appropriate height, the lifting motor 601 stops. During the polishing operation, the grinding disc rotation motor 609 is powered on and started. Its output end drives the polishing grinding disc 610 to rotate at high speed to polish the surface of the optical lens fixed by the lens clamping assembly 8. Throughout the process, the lifting mechanism 6 achieves precise and stable adjustment of the height of the polishing grinding disc 610 through the cooperation of the threaded rod 602 and the auxiliary rod 603, ensuring that the polishing operation is carried out efficiently and accurately.
[0027] Furthermore, four identical sets of movable sliders 706 are provided on the surface of the movable slide rail 705, and each pair of movable sliders 706 are symmetrically distributed. The size of the movable sliders 706 is adapted to the size of the movable slide rail 705. Through the arrangement of the movable slide rail 705 and the movable sliders 706, a precise and stable linear movement system is constructed. The four symmetrically distributed sets of movable sliders 706 can evenly distribute the load, ensuring that the base 801 is balanced in force during movement and reducing lateral offset. The sliders and slide rails are made of high-hardness alloy steel and the surface is precision ground, which makes the base 801 move smoothly with low resistance and has good wear resistance. This precise fit can also effectively absorb the vibration generated during polishing and avoid affecting the lens clamping assembly 8, providing a stable and reliable moving platform for high-precision polishing of optical lenses.
[0028] Furthermore, multiple sets of telescopic tubes 811 are arranged on the surface of the rotating disk 810, and are distributed at equal intervals around the center of the rotating disk 810. Through the arrangement of the telescopic tubes 811, an all-round adaptive lens clamping structure is formed. The multiple sets of telescopic tubes 811 distributed around the center can apply clamping force to the lens from multiple angles at the same time, so that the lens is subjected to uniform force and avoids deformation or damage caused by uneven force at a single point. The spring 815 inside each telescopic tube 811 has independent telescopicity and can automatically adjust the position and pressure of the suction cup 817 according to the slight unevenness of the lens surface to achieve flexible clamping. This design is not only suitable for standard round lenses, but also compatible with elliptical, polygonal and other irregularly shaped lenses. At the same time, the equally spaced telescopic tubes 811 keep the rotating disk 810 in good dynamic balance during rotation, reduce vibration and noise, and improve polishing quality and efficiency.
[0029] Working principle: First, according to the lens specifications, the operator starts the hydraulic cylinder 804 of the lens clamping assembly 8. The hydraulic rod 805 drives the movable seat 807 to slide along the guide groove 803, quickly adjusting the distance between the fixed seat 802 and the movable seat 807. Then, the operator controls the rotary motor 809 to rotate the rotating disk 810, so that the suction cups 817 distributed around the telescopic tube 811 adaptively fit the lens surface. The flexible support of the spring 815 ensures uniform clamping force and prevents the lens from being deformed by pressure. After the lens is fixed, the lifting motor 601 of the lifting mechanism 6 drives the threaded rod 602 to rotate. Under the guidance of the auxiliary rod 603, the first lifting block 604 drives the connecting seat 605 to rise and fall smoothly along the lifting groove 606, accurately adjusting the distance between the polishing disc 610 and the lens. At the same time, the moving motor 702 of the moving mechanism 7 drives the lead screw 703 to rotate, and the lead screw slider 704 coordinates with the four symmetrical distribution... The movable slider 706 moves along the movable slide rail 705 to drive the lens clamping assembly 8 to move horizontally, achieving precise calibration of the polishing area. During polishing, the grinding disc rotation motor 609 drives the polishing grinding disc 610 to rotate at high speed, cooperating with the rotation motor 809 to drive the lens to rotate synchronously, ensuring uniform polishing. During this period, the moving mechanism 7 and the lifting mechanism 6 are continuously linked, dynamically adjusting the relative position of the lens and the grinding disc according to the polishing parameters. The telescopic tube 811 compensates for changes in the curvature of the lens surface in real time, maintaining stable clamping. After polishing is completed, the suction cup 817 is pressed again to release the suction, and the hydraulic cylinder 804 retracts to reset the moving seat 807, allowing the lens to be removed. Throughout the process, the foot support 3 ensures the stability of the equipment, and the movable slide rail 705 and slider 706 absorb vibration, significantly improving the production quality and efficiency of optical lenses. This completes the use of an auxiliary device for a polishing machine in optical lens production.
