Description

Technical Field

[0001] This invention belongs to the field of rotating base technology, specifically relating to a rotating base for facilitating the processing of optical glass lenses. Background Technology

[0002] In the precision machining of optical glass lenses, the rotating base, as a core auxiliary device for supporting and positioning the lenses, directly affects the processing quality and efficiency of grinding, lapping, and polishing processes. Currently, most commercially available rotating bases employ a bearing-supported rotating platform structure, coupled with a drive motor to achieve circumferential rotation of the lenses, thus meeting the requirements of different processing angles and positions.

[0003] Existing technologies generally use independent three-point clamping blocks to hold optical glass lenses, and each clamping block is equipped with a rubber protective pad. When polishing optical glass lenses, especially for optical lenses with large curvature or thinness, the lenses are prone to radial slippage or circumferential movement when rotating at high speed or under force, which affects the surface accuracy and surface finish. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rotating base for convenient optical glass lens processing, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a rotating base for convenient optical glass lens processing, including an operating table, a rotary motor mounted on the bottom of the operating table, and a rotating base body mounted on the top of the output shaft of the rotary motor. The upper surface of the rotating base body has three track grooves arranged in a ring array, and the outer side of the rotating base body is equipped with three sets of clamping components arranged in a ring array. The clamping assembly includes a bracket fixed to the side of the rotating base body and a base slider slidably connected inside the first track groove. An electric telescopic rod is installed inside the bracket, and the moving end of the electric telescopic rod is connected to the side of the base slider. A second track groove is formed on the upper surface of the base slider. A sliding clamping block is slidably connected inside the second track groove of the base slider. An elastic liquid storage bladder is installed between the sliding clamping block and the inner wall of the second track groove. Arc-shaped tracks are fixed on both sides of the sliding clamping block, and side clamping plates are slidably connected to both arc-shaped tracks. A hollow tube is fixed to the back of the sliding clamping block, and the bottom of the hollow tube communicates with the elastic liquid storage bladder. Hollow telescopic rods are connected to both sides of the hollow tube and installed thereon. The ends of the two hollow telescopic rods are respectively connected to the two side clamping plates. This application utilizes a linkage design between the sliding clamping block and the side clamping plates. When the sliding clamping block contacts the lens and is pushed in the opposite direction, it squeezes the elastic reservoir. The liquid inside the elastic reservoir enters and drives the hollow telescopic rod to push the two side clamping plates to slide synchronously along the arc track, thereby achieving auxiliary clamping of the lens sidewall. This effectively prevents the lens from radially sliding or circumferentially moving during high-speed rotation or force processing, significantly improving processing stability and surface accuracy.

[0006] Preferably, the hollow telescopic rod is composed of multiple mutually adaptable hollow sleeves, and a sealing gasket is provided between each mutually adaptable hollow sleeve. The extension path of the hollow telescopic rod is arc-shaped, and the surfaces of the sliding clamping block and the side clamping plate are equipped with rubber protective pads.

[0007] Preferably, a side plate is fixed to the top side of the base slider.

[0008] Preferably, each of the side plates is fitted with an auxiliary component to increase vertical clamping stability between it and the sliding clamping block.

[0009] Preferably, the auxiliary component includes a rectangular telescopic rod fixed to the side of the side plate and internally fitted with a spring, and an L-shaped rod rotatably connected inside the sliding clamping block. A spring is fixed between the L-shaped rod and the sliding clamping block, and a clamping plate is mounted at the end of the L-shaped rod via a universal joint. This application adds an auxiliary component between the side plate and the sliding clamping block, using the rectangular telescopic rod to push the L-shaped rod to rotate, causing the clamping plate to press against the lens edge from above. Combined with the universal joint's adaptive angle adjustment, this achieves vertical auxiliary fixing of lenses with different curvatures, enhancing the vibration resistance of thin or large-curvature lenses during processing and avoiding surface damage caused by uneven clamping force.

[0010] Preferably, a hemispherical rubber block is fixed to one side of the rectangular telescopic rod near the L-shaped rod, and a rubber pad is fixed to the side of the clamping plate away from the universal joint.

[0011] Preferably, the interior of the rotating base body has three baffles arranged in a ring, and the bottom sides of the baffles are arc-shaped.

[0012] Preferably, the upper surface of the operating table is equipped with a starting assembly for controlling the synchronous movement of the three baffles. The starting assembly includes a rectangular telescopic rod II fixed to the side of the output shaft of the rotary motor and internally fitted with a spring, an annular block rotatably connected to the upper surface of the operating table, and two limiting balls fixed to the upper surface of the operating table. Three protrusions are fixed to the upper surface of the annular block, with arc-shaped structures on both sides. A contact rod is fixed to the inner ring of the annular block. This application controls the synchronous movement of the three baffles through the starting assembly. When the rotary motor drives the rectangular telescopic rod II to rotate and touch the contact rod, it pushes the annular block to rotate. The protrusions on the annular block move accordingly, and then, through the linkage of the protrusions, the baffles extend from inside the rotating base body, achieving the shielding and collection of processing debris, reducing the risk of debris splashing and scratching the lens surface, while also facilitating cleaning and improving the safety and cleanliness of the processing environment.

[0013] Preferably, a rubber sleeve is fixed to the movable part of the rectangular telescopic rod two, the contact rod is located between the two limiting balls, and the contact rod is located on the movement trajectory of the rectangular telescopic rod two.

[0014] The advantages of this application are: (1) This application uses the linkage design of sliding clamping block and side clamping plate. When the sliding clamping block contacts the lens and is pushed in the opposite direction, it squeezes the elastic reservoir. The liquid in the elastic reservoir enters and drives the hollow telescopic rod to push the two side clamping plates to slide synchronously along the arc track, thereby achieving auxiliary clamping of the lens sidewall. This effectively prevents the lens from radially sliding or circumferentially moving when it is rotated at high speed or under force, and significantly improves processing stability and surface accuracy.

[0015] (2) An auxiliary component is added between the side plate and the sliding clamping block. The rectangular telescopic rod pushes the L-shaped rod to rotate, so that the clamping plate presses the edge of the lens from above. Combined with the universal joint to adaptively adjust the angle, it can achieve vertical auxiliary fixation of lenses with different curvatures, enhance the vibration resistance of thin or large curvature lenses during processing, and avoid surface damage caused by uneven clamping force.

[0016] (3) This application controls the synchronous movement of three baffles by starting the component. When the rotary motor drives the rectangular telescopic rod two to rotate and touch the contact rod, it pushes the ring block to rotate. The protrusion on the ring block moves along with it, and then the baffle extends out from the inside of the rotating base body through the linkage of the protrusion to block and collect the processing debris, reduce the risk of debris splashing and scratching the lens surface, and facilitate cleaning, thereby improving the safety and cleanliness of the processing environment.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, as Figures 1-5 As shown, a rotary base for convenient processing of optical glass lenses includes an operating table 100, a rotary motor 200 is mounted on the bottom of the operating table 100, and a rotary base body 300 is mounted on the top of the output shaft of the rotary motor 200. The upper surface of the rotating base body 300 is provided with three track grooves 400 in a ring array, and the outer side of the rotating base body 300 is equipped with three sets of clamping components 500 in a ring array. The clamping assembly 500 includes a bracket 501 fixed to the side of the rotating base body 300 and a base slider 503 slidably connected inside the first track groove 400. An electric telescopic rod 502 is installed inside the bracket 501, and the moving end of the electric telescopic rod 502 is connected to the side of the base slider 503. A second track groove 504 is formed on the upper surface of the base slider 503. A sliding clamping block 505 is slidably connected inside the second track groove 504 of the base slider 503. An elastic liquid storage bladder 508 is installed between the sliding clamping block 505 and the inner wall of the second track groove 504. Arc-shaped tracks 506 are fixed to both sides of the sliding clamping block 505. Side clamps 507 are slidably connected to both sides of the arc-shaped track 506. A hollow tube 510 is fixed to the back of the sliding clamping block 505. The bottom of the hollow tube 510 is connected to the elastic liquid storage bladder 508. Both sides of the hollow tube 510 are connected and equipped with hollow telescopic rods 511. The ends of the two hollow telescopic rods 511 are respectively connected to the two side clamps 507. The hollow telescopic rod 511 is composed of multiple mutually compatible hollow sleeves, and a sealing gasket is provided between each mutually compatible hollow sleeve. The extension path of the hollow telescopic rod 511 is arc-shaped. Rubber protective pads are installed on the surfaces of the sliding clamping block 505 and the side clamps 507. This application utilizes a linkage design between the sliding clamping block 505 and the side clamping plate 507. When the sliding clamping block 505 contacts the lens and is pushed in the opposite direction, it squeezes the elastic liquid reservoir 508. The liquid inside the elastic liquid reservoir 508 enters and drives the hollow telescopic rod 511 to push the two side clamping plates 507 to slide synchronously along the arc track 506, thereby achieving auxiliary clamping of the lens sidewall. This effectively prevents the lens from radially sliding or circumferentially moving during high-speed rotation or force processing, significantly improving processing stability and surface accuracy.

[0021] In practical use, the optical glass lens is placed in the center area of ​​the upper surface of the rotating base body 300. The electric telescopic rod 502 in the three sets of clamping assemblies 500 is activated, extending its moving end and pushing the base slider 503 along the track groove 400 towards the lens. As the base slider 503 moves, it causes the sliding clamping block 505 on it to simultaneously approach the edge of the lens. When the rubber pad at the front end of the sliding clamping block 505 contacts the side wall of the lens, because the lens position is fixed, the sliding clamping block 505 experiences reverse resistance. The base slider 503 slides backward along the second track groove 504. When the sliding clamping block 505 moves backward, it squeezes the elastic liquid storage bladder 508 between its rear and the inner wall of the second track groove 504. After the liquid inside the bladder is compressed, it flows into the hollow telescopic rods 511 on both sides through the connected hollow tube 510. The liquid pressure pushes each section of the hollow telescopic rod 511 to extend step by step along the arc path. Its end pushes the side clamps 507 on both sides to slide synchronously along the arc track 506, wrapping and clamping the edge of the lens from both sides of the lens sidewall. At this time, the sliding clamping block 505 completes the clamping of the lens in the main radial direction, and the side clamping plates 507 on both sides provide circumferential auxiliary clamping force. When the rotary motor 200 drives the rotating base body 300 to rotate, the lens is firmly constrained in both the radial and circumferential directions, effectively preventing sliding or movement under the action of high-speed rotation or grinding force.

[0022] Example 2, as Figures 6-7 As shown, based on Embodiment 1, a side plate 509 is fixed to the top side of the base slider 503. Each side plate 509 and the sliding clamping block 505 are equipped with an auxiliary component 600 to increase the vertical clamping stability. The auxiliary component 600 includes a rectangular telescopic rod 601 fixed to the side of the side plate 509 and equipped with a spring inside, and an L-shaped rod 602 rotatably connected inside the sliding clamping block 505. A spring piece 604 is fixed between the L-shaped rod 602 and the sliding clamping block 505. A clamping plate 606 is assembled at the end of the L-shaped rod 602 through a universal joint 605. A hemispherical rubber block 603 is fixed to the side of the rectangular telescopic rod 601 near the L-shaped rod 602, and a rubber pad is fixed to the side of the clamping plate 606 away from the universal joint 605. This application adds an auxiliary component 600 between the side plate 509 and the sliding clamping block 505. The rectangular telescopic rod 601 pushes the L-shaped rod 602 to rotate, so that the clamping plate 606 presses the edge of the lens from above. Combined with the universal joint 605 to adaptively adjust the angle, it realizes the vertical auxiliary fixation of lenses with different curvatures, enhances the vibration resistance of thin or large curvature lenses during the processing, and avoids surface damage caused by uneven clamping force.

[0023] In actual use, the spring inside the rectangular telescopic rod 601 is in a compressed state, always applying an outward pushing force to its movable rod, so that the hemispherical rubber block 603 at the front end of the movable rod remains in contact with the upper end of the L-shaped rod 602. When the sliding clamping block 505 moves backward due to contact with the lens, the L-shaped rod 602 fixed inside it moves backward synchronously. At this time, the hemispherical rubber block 603 slides forward relative to the L-shaped rod 602, pushing the L-shaped rod 602 to rotate around its rotation center while compressing the spring 604. The clamping plate 606, connected to the end of the L-shaped rod 602 via the universal joint 605, moves downward as the L-shaped rod 602 rotates, pressing against the upper edge of the lens surface from the vertical direction. The universal joint 605 automatically deflects according to the curvature of the lens surface, so that the rubber pad on the underside of the clamping plate 606 fits against the lens surface. The spring 604 provides a continuous reverse elastic force, making the clamping force gentle and adjustable, avoiding rigid impact damage to the lens. On the basis of horizontal clamping, this component applies an additional vertical downward clamping force, significantly enhancing the vibration resistance stability of thin-walled or high-curvature lenses during processing, while preventing surface deformation caused by uneven clamping force.

[0024] Example 3, as Figures 8-9 As shown, based on Embodiment 1, three ring-shaped baffles 701 are slidably connected through the interior of the rotating base body 300. The bottom sides of the baffles 701 are arc-shaped. The upper surface of the operating table 100 is equipped with a starting assembly 700 for controlling the synchronous movement of the three baffles 701. The starting assembly 700 includes a rectangular telescopic rod 703 fixed to the side of the output shaft of the rotary motor 200 and equipped with a spring inside, an annular block 702 rotatably connected to the upper surface of the operating table 100, and a ring block 702 fixed to the operating table 100. Two limiting balls 707 are fixed on the upper surface of the 00 ring block 702. Three protrusions 705 are fixed on the upper surface of the ring block 702. Both sides of the three protrusions 705 are arc-shaped. Both sides of the bottom of the baffle 701 are arc-shaped to cooperate with the subsequent protrusions 705. A contact rod 706 is fixed on the inner ring of the ring block 702. A rubber sleeve 704 is fixed at the movable rod of the rectangular telescopic rod 703. The contact rod 706 is located between the two limiting balls 707 and is located on the movement trajectory of the rectangular telescopic rod 703. This application controls the synchronous movement of three baffles 701 by starting component 700. When the rotary motor 200 drives the rectangular telescopic rod 703 to rotate and touch the contact rod 706, it pushes the annular block 702 to rotate. The protrusion 705 on the annular block 702 moves accordingly, and then the baffle 701 extends out from the inside of the rotating base body 300 through the linkage of the protrusion 705, so as to block and collect the processing debris, reduce the risk of debris splashing and scratching the lens surface, and facilitate cleaning, thereby improving the safety and cleanliness of the processing environment.

[0025] In actual use, the three baffles 701 are slidably connected inside the rotating base body 300. Initially, they are fully retracted and do not interfere with the placement and clamping of the lens. After the rotary motor 200 is started, its output shaft drives the rectangular telescopic rod 703 on the side to rotate synchronously. The movable end of the rectangular telescopic rod 703 is fixed with a rubber sleeve 704. When it rotates to meet the contact rod 706 on the inner ring of the annular block 702, it pushes the contact rod 706 to drive the annular block 702 to rotate on the upper surface of the operating table 100. The two limit balls 707 limit the rotation stroke of the contact rod 706 to ensure that each touch only pushes the set angle. When the annular block 702 rotates, the three protrusions 705 fixed on its upper surface move accordingly. The arc-shaped surfaces on both sides of each protrusion 705 gradually contact the bottom of the corresponding baffle 701. Using the arc-shaped surface, the baffle 701 is pushed upward from inside the rotating base body 300 and extends to the height of the lens periphery. The extended baffle 701 forms an annular enclosure to collect the debris splashed during processing. Due to the presence of the two limiting balls 707, the displacement of the contact rod 706 is restricted. Therefore, when the rectangular telescopic rod 703 pushes the contact rod 706 to rotate until it contacts the limiting ball 707, the contact rod 706 no longer moves. The rectangular telescopic rod 703 is telescopic, so it will continue to rotate after retracting. During reset, the rectangular telescopic rod 703 contacts the contact rod 706 again in the opposite direction due to the reverse rotation of the rotary motor 200, causing the annular block 702 to slide in the opposite direction, and the protrusion block 705 to disengage from the baffle 701. The baffle 701 self-repositions, completing one working cycle.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
