Description

Technical Field

[0001] The present invention belongs to the technical field of lens polishing, and particularly relates to a polishing device for aspherical lenses. Background Art

[0002] The surface curvature of an aspherical lens is different from that of a traditional spherical lens. The aspherical lens adopts a complex curved surface design, and the radius of curvature gradually changes from the center to the edge, which can reduce the aberration problem and provide a more natural visual experience than traditional spherical lenses.

[0003] Currently, a Chinese invention with the publication number: CN114131461B discloses an optical processing lens polishing device. Existing aspherical lenses generally need to be polished to increase the light transmittance of the lens. Before polishing, the aspherical lens needs to be clamped and fixed to prevent the aspherical lens from shifting during the polishing process. Since the polishing wheel inside the existing polishing device generally can only move vertically up and down along with the conveying section of the cylinder or the electric telescopic rod, it is necessary to ensure that the aspherical lens is positioned at the center of the polishing wheel during the clamping process. However, the existing polishing device cannot perform centering clamping on the aspherical lens, and it is often necessary to adjust the clamping position of the aspherical lens multiple times. Therefore, the aspherical lens cannot be quickly clamped and aligned with the center of the polishing wheel at one time, which affects the clamping efficiency. And dust will be generated during the polishing process of the aspherical lens. The existing polishing device generally uses flowing water to adsorb dust to reduce dust dispersion. However, the water source will become turbid after adsorbing dust and cannot be reused. Therefore, water is wasted during the polishing process, increasing the polishing cost of the aspherical lens. Summary of the Invention

[0004] The purpose of the present invention is to provide a polishing device for aspherical lenses, which has the advantages of conveniently and accurately centering and clamping the aspherical lens at the center position at the bottom of the polishing wheel, while the polishing wheel synchronously moves down to the top of the aspherical lens for polishing treatment and the function of using circulating water to adsorb the polishing dust of the aspherical lens.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A polishing device for aspherical lenses, including a fixed seat, a support platform frame is bolted to the top of the fixed seat, a storage water tank is bolted inside the fixed seat, a polishing platform is welded inside the storage water tank, a limit seat is bolted to the bottom of the support platform frame, and a centering clamping mechanism and a polishing mechanism that cooperate with the polishing platform and the limit seat are installed inside both the fixed seat and the support platform frame.

[0006] Adopting the above technical solution, the first motor drives the third bevel gear to engage with all the fourth bevel gears inside the polishing platform synchronously, so as to drive the adjusting clamping plates on the top of the polishing platform to slide close to each other synchronously. Thus, the aspherical lens can be accurately centered and clamped at the center position on the top of the polishing platform, which is convenient for quickly vertically aligning with the polishing wheel. When driving the rotating seat to slide downward synchronously, the diamond groove slide cylinder can slide up and down on the surface of the diamond-shaped rotating rod and drive the diamond groove slide cylinder to rotate by using the diamond groove. Thus, after the adjusting clamping plates center and clamp the aspherical lens, the polishing wheel moves to the top of the aspherical lens synchronously to polish the top of the aspherical lens, improving the processing efficiency. By synchronously driving the pump impeller to rotate inside the water suction pump chamber of the second motor, the water source in the storage water tank is pumped into the water outlet hole and discharged downward. Thus, the dust polished out can be adsorbed, reducing pollution. At the same time, the dust in the water is filtered by the sliding mesh plate, and then the water source can also be recycled, improving the practicability.

[0007] The present invention is further configured as: the centering and clamping mechanism includes a first motor bolted to the side of the polishing platform away from the support platform frame. Transmission rods are rotatably connected inside both the support platform frame and the fixed seat. Synchronous wheels are fixedly sleeved at one ends of the two transmission rods close to the first motor. Synchronous belts are sleeved on the surfaces of the two synchronous wheels. Tooth groove structures that mesh with each other are provided on the inner surface of the synchronous belt and the outer surface of the synchronous wheel. The output end of the first motor is bolted to one end of the transmission rod inside the support platform frame. First bevel gears and second bevel gears are respectively bolted to the ends of the two transmission rods away from the synchronous wheels.

[0008] Adopting the above technical solution, the tooth groove structures provided on the inner surface of the synchronous belt and the outer surface of the synchronous wheel can enable meshing transmission between the synchronous belt and the synchronous wheel, prevent the synchronous belt from slipping on the surface of the synchronous wheel, and thus improve the stability of transmission.

[0009] The present invention is further configured as follows: A first screw rod is rotatably connected inside the storage water tank. A large bevel gear meshing with the second bevel gear is bolted to the bottom of the first screw rod. A third bevel gear rotatably connected to the polishing platform is bolted to the top of the first screw rod. A fixed cylinder is welded inside the polishing platform. A second screw rod rotatably connected to the polishing platform penetrates through the inside of the fixed cylinder. A fourth bevel gear meshing with the third bevel gear is bolted to one end of the second screw rod close to the third bevel gear. A second screw sleeve is threadedly sleeved on the surface of the second screw rod. A sliding ring slidably sleeved with the fixed cylinder is fixedly connected to the surface of the second screw sleeve. A sliding plate slidably connected to the polishing platform is welded to the top of the sliding ring. An adjusting screw shaft is rotatably connected inside the sliding plate. A connecting screw sleeve is threadedly sleeved on the surface of the adjusting screw shaft. An adjusting clamping plate bolted to the connecting screw sleeve is slidably connected to the top of the sliding plate. A precision scale for cooperating with the adjusting clamping plate is marked on one side of the sliding plate.

[0010] With the above technical solution, since the bottom of the second screw sleeve is fixedly connected to the inner surface of the sliding ring, the second screw sleeve slides at the bottom of the fixed cylinder. Therefore, the fixed cylinder can protect the top surface of the second screw rod, and the water will automatically flow out from inside the polishing platform 4, preventing the water source from driving the dust to accumulate on the surface of the second screw rod, and ensuring that the second screw sleeve can stably engage with the second screw rod in a threaded manner.

[0011] The present invention is further configured as follows: A sliding cylinder is slidably connected inside the limiting seat. A threaded cylinder rotatably connected to the support platform frame penetrates through and is threadedly connected inside the sliding cylinder. A tapered tooth ring meshing with the first bevel gear is fixedly sleeved on the surface of the top of the threaded cylinder. A limiting slider slidably connected to the sliding cylinder is welded inside the limiting seat. A rotating seat is arranged at the bottom of the sliding cylinder. A polishing wheel is welded to the bottom of the rotating seat.

[0012] With the above technical solution, when the second bevel gear meshes with the large bevel gear, the torque of the large bevel gear is relatively large, resulting in a slower rotation speed of the first screw rod, thereby reducing the sliding speed of the adjusting clamping plate. Therefore, even if the distance between the rotating seat and the polishing platform is relatively far and the distance between multiple adjusting clamping plates is relatively close, the adjusting clamping plate can still move to the top of the aspherical lens synchronously after centering and clamping the aspherical lens.

[0013] The present invention is further configured as follows: The polishing mechanism includes a second motor arranged on the top of the first motor and bolted to the support platform frame. The output end of the second motor is bolted with a fifth bevel gear rotatably connected to the support platform frame. A diamond groove sliding cylinder bolted to the top of the rotating seat penetrates through the inside of the threaded cylinder. The diamond groove sliding cylinder is rotatably connected through the inside of the sliding cylinder. A diamond-shaped rotating rod is slidably connected through the inside of the diamond groove sliding cylinder. A sixth bevel gear meshing with the fifth bevel gear is bolted to the top of the diamond-shaped rotating rod.

[0014] With the above technical solution, since the diamond groove sliding cylinder slides up and down on the surface of the diamond-shaped rotating rod and the surface of the diamond groove sliding cylinder does not contact the inside of the threaded cylinder, when the sliding cylinder drives the rotating seat to slide downwards, the rotating seat can synchronously pull the diamond groove sliding cylinder to slide downwards on the surface of the diamond-shaped rotating rod. Even when the diamond groove sliding cylinder slides downwards, the diamond-shaped rotating rod can drive the diamond groove sliding cylinder to rotate through the diamond groove.

[0015] The present invention is further configured as follows: a second motor water pump chamber is welded to the top of the support platform frame, and one end of the top of the diamond-shaped rotating rod located inside the second motor water pump chamber is bolted with a pump impeller rotatably connected to the second motor water pump chamber. An inlet hole is penetrated and opened inside the diamond-shaped rotating rod. One side of the second motor water pump chamber is fixedly communicated with a connecting pipe fixedly communicated with the inside of the storage water tank. Communication holes communicated with the inlet hole are opened inside both the diamond groove sliding cylinder and the rotating seat.

[0016] With the above technical solution, the water source stored inside the storage water tank is pumped into the inside of the second motor water pump chamber through the connecting pipe, so that when the polishing wheel rotates to polish the top of the aspherical lens, the dust polished can be adsorbed by the flowing water, reducing the dust pollution during polishing.

[0017] The present invention is further configured as follows: a polishing piece is bonded to the bottom of the polishing wheel, and water outlet holes communicated with the communication holes are opened inside both the polishing wheel and the polishing piece.

[0018] With the above technical solution, the water outlet holes are used to polish the aspherical lens by the polishing wheel, and the polishing accuracy of the aspherical lens can be adjusted by replacing different polishing pieces. Opening a plurality of water outlet holes can better make the water source flow out evenly, improving the dust adsorption effect.

[0019] The present invention is further configured as follows: a first screw sleeve is threadedly sleeved on the surface of the first screw. Sliding rods slidably connected to the storage water tank are welded on both sides of the surface of the first screw sleeve. A sliding mesh plate slidably connected to the inside of the storage water tank is welded to the end of the sliding rod away from the first screw sleeve. Rubber folding pieces are fixedly connected to both sides of the top and bottom of the first screw sleeve.

[0020] With the above technical solution, through the threaded engagement of the first screw and the first screw sleeve, the sliding mesh plate is driven to slide upwards inside the storage water tank through the sliding rod, filtering the dust in the water source out of the water surface, facilitating the cleaning of the dust on the top of the sliding mesh plate. A relatively fine filter cloth can also be installed inside according to needs, thereby ensuring effective filtering of the dust and improving the cleanliness of the water source after filtration. By installing the rubber folding pieces that can be telescoped and folded, the rubber folding pieces are driven to seal and isolate the chute inside the storage water tank when the sliding rod slides up and down, thereby preventing the water inside the storage water tank from seeping onto the surface of the first screw.

[0021] The present invention is further configured such that: a lens pad is adhesively bonded to the top of the polishing platform.

[0022] By adopting the above technical solution, it is used to support the placed aspherical lens, so that the adjusting clamping plate can centeringly clamp the aspherical lens.

[0023] The present invention is further configured such that: at the top of the inner surface of the rhombic groove sliding cylinder and at one end of the outer surface of the rhombic rotating rod close to the second motor water suction pump chamber, a metal sealing ring is clamped.

[0024] By adopting the above technical solution, it is used for waterproof sealing between the rhombic rotating rod and the rhombic groove sliding cylinder and between the rhombic rotating rod and the support platform frame, thereby preventing the water sucked by the pump from leaking out through the gap into the water inlet hole.

[0025] In summary, the present invention has the following beneficial effects: 1. The first motor drives the third bevel gear to synchronously engage with all the fourth bevel gears inside the polishing platform, so that the adjusting clamping plates on the top of the polishing platform can slide close to each other synchronously. Thus, the aspherical lens can be accurately centered and clamped at the central position on the top of the polishing platform, which is convenient for quickly and vertically aligning with the polishing wheel; 2. When driving the rotating seat to slide downward synchronously, the rhombic groove sliding cylinder can slide up and down on the surface of the rhombic rotating rod and drive the rhombic groove sliding cylinder to rotate by using the rhombic groove. Thus, after the adjusting clamping plate centeringly clamps the aspherical lens, the polishing wheel synchronously moves to the top of the aspherical lens to polish the top of the aspherical lens, improving the processing efficiency; 3. By synchronously driving the pump impeller to rotate inside the second motor water suction pump chamber, the water source in the storage water tank is pumped into the water outlet hole and discharged downward. Thus, the polished dust can be adsorbed, reducing pollution. At the same time, the dust in the water is filtered by the sliding mesh plate, and further, the water source can also be recycled, improving the practicability. Description of the Drawings

Detailed implementation mode

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1: Refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9, A polishing device for an aspherical lens, comprising a fixed base 1, a support platform 2 bolted to the top of the fixed base 1, a storage water tank 3 bolted inside the fixed base 1, a polishing platform 4 welded inside the storage water tank 3, a limit seat 5 bolted to the bottom of the support platform 2, and a centering clamping mechanism 6 and a polishing mechanism 7 which are installed inside both the fixed base 1 and the support platform 2 and cooperate with the polishing platform 4 and the limit seat 5. The first motor 601 drives the third bevel gear 609 to synchronously mesh with all the fourth bevel gears 611 inside the polishing platform 4, so as to drive the adjusting clamping plates 615 on the top of the polishing platform 4 to slide closer to each other synchronously. Thus, the aspherical lens can be accurately centered and clamped at the central position on the top of the polishing platform 4, facilitating quick vertical alignment with the polishing wheel. When the second motor 701 drives the rotating seat 620 to slide down synchronously, the diamond groove sliding cylinder 704 can slide up and down on the surface of the diamond-shaped rotating rod 703 and rotate the diamond groove sliding cylinder 704 by using the diamond groove. Thus, after the adjusting clamping plates 615 center and clamp the aspherical lens, the polishing wheel 621 moves to the top of the aspherical lens synchronously to polish the top of the aspherical lens, improving the processing efficiency.

[0030] Reference Figure 2 , Figure 6 , The centering clamping mechanism 6 includes a first motor 601 bolted to the side of the support platform 2 away from the polishing platform 4. Transmission rods 602 are rotatably connected inside both the support platform 2 and the fixed base 1. Synchronous wheels 604 are fixedly sleeved at one ends of the two transmission rods 602 close to the first motor 601. Synchronous belts 606 are sleeved on the surfaces of the two synchronous wheels 604. Tooth groove structures that mesh with each other are provided on the inner surfaces of the synchronous belts 606 and the outer surfaces of the synchronous wheels 604. The output end of the first motor 601 is bolted to one end of the transmission rod 602 inside the support platform 2. First bevel gears 603 and second bevel gears 605 are respectively bolted to the ends of the two transmission rods 602 away from the synchronous wheels 604. The tooth groove structures provided on the inner surfaces of the synchronous belts 606 and the outer surfaces of the synchronous wheels 604 can enable meshing transmission between the synchronous belts 606 and the synchronous wheels 604, preventing the synchronous belts 606 from slipping on the surfaces of the synchronous wheels 604, thereby improving the stability of transmission.

[0031] Reference Figure 2 , Figure 7 , Figure 8 , Figure 9, a first screw rod 608 is rotatably connected inside the storage water tank 3. A large bevel gear 607 that meshes with a second bevel gear 605 is bolted to the bottom of the first screw rod 608. A third bevel gear 609 that is rotatably connected to the polishing platform 4 is bolted to the top of the first screw rod 608. A fixed cylinder 610 is welded inside the polishing platform 4. A second screw rod 614 that is rotatably connected to the polishing platform 4 is disposed through the inside of the fixed cylinder 610. A fourth bevel gear 611 that meshes with the third bevel gear 609 is bolted to one end of the second screw rod 614 close to the third bevel gear 609. A second screw sleeve 613 is threadedly sleeved on the surface of the second screw rod 614. A sliding ring 612 that is slidably sleeved with the fixed cylinder 610 is fixedly connected to the surface of the second screw sleeve 613. A sliding plate 627 that is slidably connected to the polishing platform 4 is welded to the top of the sliding ring 612. An adjusting screw shaft 629 is rotatably connected inside the sliding plate 627. A connecting screw sleeve 630 is threadedly sleeved on the surface of the adjusting screw shaft 629. An adjusting clamping plate 615 that is bolted to the connecting screw sleeve 630 is slidably connected to the top of the sliding plate 627. A precision scale 628 that is used in cooperation with the adjusting clamping plate 615 is marked on one side of the sliding plate 627. Since the bottom of the second screw sleeve 613 is fixedly connected to the inner surface of the sliding ring 612, the second screw sleeve 613 slides at the bottom of the fixed cylinder 610. Therefore, the fixed cylinder 610 can protect the top surface of the second screw rod 614. Moisture will automatically flow out from inside the polishing platform 4, preventing the water source from driving dust to accumulate on the surface of the second screw rod 614 and ensuring that the second screw sleeve 613 can stably threadedly engage with the second screw rod 614.

[0032] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , a sliding cylinder 617 is slidably connected inside the limit seat 5. A threaded cylinder 616 that is rotatably connected to the support platform frame 2 is threadedly disposed through the inside of the sliding cylinder 617. A tapered tooth ring 619 that meshes with the first bevel gear 603 is fixedly sleeved on the surface of the top of the threaded cylinder 616. A limit slider 618 that is slidably connected to the sliding cylinder 617 is welded inside the limit seat 5. A rotating seat 620 is disposed at the bottom of the sliding cylinder 617. A polishing wheel 621 is welded to the bottom of the rotating seat 620. Since the torque of the large bevel gear 607 is relatively large when the second bevel gear 605 meshes with the large bevel gear 607, the rotation speed of the first screw rod 608 is slow, thereby reducing the sliding speed of the adjusting clamping plate 615. Therefore, even if the distance between the rotating seat 620 and the polishing platform 4 is far and the distance between multiple adjusting clamping plates 615 is close, the adjusting clamping plate 615 can be synchronously moved to the top of the aspherical lens after centering and clamping the aspherical lens.

[0033] Reference Figure 4 , Figure 5, a polishing sheet 623 is adhesively bonded to the bottom of the polishing wheel 621, and water outlet holes 622 communicating with the communication hole 709 are opened inside both the polishing wheel 621 and the polishing sheet 623. The water outlet holes 622 are used to polish the aspherical lens by the polishing wheel 621, and the polishing accuracy of the aspherical lens can be adjusted by replacing different polishing sheets 623. Opening a plurality of water outlet holes 622 can better make the water source flow out evenly and improve the dust adsorption effect.

[0034] Reference Figure 7 , a first screw sleeve 624 is threadedly sleeved on the surface of the first screw 608. Sliding rods 625 slidably connected to the storage water tank 3 are welded on both sides of the surface of the first screw sleeve 624. A sliding mesh plate 626 slidably connected to the inside of the storage water tank 3 is welded to one end of the sliding rod 625 away from the first screw sleeve 624. Rubber folding sheets 9 are fixedly connected to both sides of the top and bottom of the first screw sleeve 624. Through the threaded engagement of the first screw 608 and the first screw sleeve 624, the sliding mesh plate 626 is driven to slide upward inside the storage water tank 3 through the sliding rod 625, filtering the dust in the water source out of the water surface, facilitating the cleaning of the dust on the top of the sliding mesh plate 626. A relatively fine filter cloth can also be installed inside according to needs, so as to ensure effective filtering of dust and improve the cleanliness of the water source after filtration. By installing the retractable and foldable rubber folding sheets 9, the rubber folding sheets 9 are driven to seal and isolate the chute inside the storage water tank 3 when the sliding rod 625 slides up and down, so as to prevent the water inside the storage water tank 3 from seeping onto the surface of the first screw 608.

[0035] Brief description of the usage process: First, calibrate the equipment according to the diameter and thickness of the lenses processed in this batch. Adjust the clamping distance according to the polished thickness. Rotate the adjusting screw shaft 629 to engage with the connecting screw sleeve 630 in a threaded manner, so as to drive the adjusting clamping plate 615 to slide on the top of the sliding plate 627. The position of a single adjusting clamping plate 615 can also be independently adjusted to adapt to aspherical lenses of different thicknesses. The precision scale 628 marked on the side of the sliding plate 627 can be used to precisely adjust the adjusting clamping plate 615. After adjustment, start the first motor 601 and use the synchronous pulley 604 and synchronous belt 606 for transmission, so as to synchronously drive the two transmission rods 602 to rotate, and the transmission rods 602 drive the first bevel gear 603 to engage with the conical tooth ring 619 and drive the second bevel gear 605 to engage with the large bevel gear 607 respectively. Then, drive the first screw rod 608 to rotate through the large bevel gear 607, so that the top of the first screw rod 608 and the third bevel gear 609 can be synchronously engaged with all the fourth bevel gears 611 inside the polishing platform 4, thereby driving the second screw rod 614 inside to rotate. Then, engage the second screw rod 614 with the second screw sleeve 613 in a threaded manner. Under the limitation of the fixed cylinder 610, the second screw sleeve 613 and the sliding ring 612 drive the sliding ring 612 to slide on the surface of the fixed cylinder 610, so that the adjusting clamping plates 615 on the top of the polishing platform 4 can slide close to each other, and clamp and fix the aspherical lens on the top of the polishing platform 4. Since multiple adjusting clamping plates 615 all move synchronously, the aspherical lens can be accurately clamped and positioned at the center of the polishing platform 4; At the same time, drive the threaded cylinder 616 to rotate through the conical tooth ring 619 and engage with the sliding cylinder 617 in a threaded manner. The sliding cylinder 617 slides downward inside the limit seat 5 under the limitation of the limit slider 618, so as to drive the rotating seat 620 to slide downward, so that the polishing wheel 621 can move downward to the top of the aspherical lens synchronously during the centering and clamping process of the adjusting clamping plate 615 on the aspherical lens. Since the torque of the large bevel gear 607 is relatively large when the second bevel gear 605 engages with the large bevel gear 607, the rotation speed of the first screw rod 608 is slow, so as to reduce the sliding speed of the adjusting clamping plate 615. Therefore, even if the distance between the rotating seat 620 and the polishing platform 4 is far and the distance between multiple adjusting clamping plates 615 is close, after the adjusting clamping plate 615 centers and clamps the aspherical lens, the polishing wheel 621 can move to the top of the aspherical lens synchronously.

[0036] Embodiment 2: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7, A polishing device for an aspherical lens, including a fixed base 1, a support platform frame 2 bolted to the top of the fixed base 1, a storage water tank 3 bolted inside the fixed base 1, a polishing platform 4 welded inside the storage water tank 3, a limit seat 5 bolted to the bottom of the support platform frame 2, and a centering clamping mechanism 6 and a polishing mechanism 7 that are installed inside both the fixed base 1 and the support platform frame 2 and cooperate with the polishing platform 4 and the limit seat 5. By the second motor 701 synchronously driving the pump impeller 706 to rotate inside the second motor water suction pump chamber 8, the water source inside the storage water tank 3 is pumped into the water outlet hole 622 and discharged downward. Thus, the polished dust can be adsorbed, reducing pollution. At the same time, the dust in the water is filtered by the sliding mesh plate 626, and then the water source can also be recycled, improving the practicality.

[0037] Reference Figure 2 , Figure 3 , Figure 4 , The polishing mechanism 7 includes a second motor 701 disposed on the top of the first motor 601 and bolted to the support platform frame 2. The output end of the second motor 701 is bolted with a fifth bevel gear 702 rotatably connected to the support platform frame 2. A rhombus groove sliding cylinder 704 bolted to the top of the rotating seat 620 penetrates through the inside of the threaded cylinder 616. The rhombus groove sliding cylinder 704 is rotatably connected through the inside of the sliding cylinder 617. A rhombus rotating rod 703 is slidably connected through the inside of the rhombus groove sliding cylinder 704. The top of the rhombus rotating rod 703 is bolted with a sixth bevel gear 705 meshing with the fifth bevel gear 702. Since the rhombus groove sliding cylinder 704 slides up and down on the surface of the rhombus rotating rod 703 and the surface of the rhombus groove sliding cylinder 704 does not contact the inside of the threaded cylinder 616, when the sliding cylinder 617 drives the rotating seat 620 to slide downward, the rotating seat 620 can synchronously pull the rhombus groove sliding cylinder 704 to slide downward on the surface of the rhombus rotating rod 703. Even when the rhombus groove sliding cylinder 704 slides downward, the rhombus rotating rod 703 can drive the rhombus groove sliding cylinder 704 to rotate through the rhombus groove.

[0038] Reference Figure 2 , Figure 3 , Figure 7 , A second motor water suction pump chamber 8 is welded to the top of the support platform frame 2. One end of the top of the rhombus rotating rod 703 located inside the second motor water suction pump chamber 8 is bolted with a pump impeller 706 rotatably connected to the second motor water suction pump chamber 8. A water inlet hole 707 is penetrated and opened inside the rhombus rotating rod 703. One side of the second motor water suction pump chamber 8 is fixedly communicated with a connecting pipe 708 fixedly communicated with the inside of the storage water tank 3. Communication holes 709 communicated with the water inlet hole 707 are opened inside both the rhombus groove sliding cylinder 704 and the rotating seat 620. The water source stored inside the storage water tank 3 is pumped into the inside of the second motor water suction pump chamber 8 through the connecting pipe 708, so that when the polishing wheel 621 rotates to polish the top of the aspherical lens, the polished dust can be adsorbed by the flowing water, reducing the dust pollution during polishing.

[0039] Reference Figure 8 , a lens pad 10 is adhesively bonded to the top of the polishing platform 4. It is used to support the placed aspherical lens, so that the adjusting clamp 615 can centeringly clamp the aspherical lens.

[0040] Refer to Figure Figure 2 、 Figure 4 , a metal sealing ring 11 is clamped at the top of the inner surface of the diamond groove sliding cylinder 704 and at one end of the outer surface of the diamond-shaped rotating rod 703 close to the second motor water suction pump chamber 8 and between the diamond-shaped rotating rod 703 and the support platform frame 2. It is used for waterproof sealing between the diamond-shaped rotating rod 703 and the diamond groove sliding cylinder 704 and between the diamond-shaped rotating rod 703 and the support platform frame 2, so as to prevent the water sucked by the pump from leaking out through the gap into the water inlet hole 707.

[0041] Brief description of the usage process: By starting the second motor 701 to drive the fifth bevel gear 702 to rotate and engage with the sixth bevel gear 705, the diamond-shaped rotating rod 703 is driven to rotate inside the diamond groove sliding cylinder 704, and the diamond-shaped grooves on the surface of the diamond-shaped rotating rod 703 and inside the diamond groove sliding cylinder 704 approach each other, so that the diamond-shaped rotating rod 703 can synchronously drive the diamond groove sliding cylinder 704 to rotate axially, and then the diamond groove sliding cylinder 704 drives the polishing wheel 621 at the bottom of the rotating seat 620 to rotate, so that the polishing wheel 621 polishes the top of the aspherical lens. At the same time, since the diamond groove sliding cylinder 704 slides up and down on the surface of the diamond-shaped rotating rod 703 and the surface of the diamond groove sliding cylinder 704 does not contact the inside of the threaded cylinder 616, when the sliding cylinder 617 drives the rotating seat 620 to slide down, the rotating seat 620 can synchronously pull the diamond groove sliding cylinder 704 to slide down on the surface of the diamond-shaped rotating rod 703, that is, even if the diamond groove sliding cylinder 704 slides down, the diamond-shaped rotating rod 703 can drive the diamond groove sliding cylinder 704 to rotate through the diamond groove.

[0042] After that, the pump impeller 706 at the top is driven by the diamond-shaped rotating rod 703 to rotate inside the second motor water suction pump chamber 8, so that the pump impeller 706 pumps the water stored in the storage water tank 3 into the second motor water suction pump chamber 8 through the connecting pipe 708. At the same time, the water source enters the inside of the diamond-shaped rotating rod 703 through the water inlet hole 707. Since the water inlet hole 707 is communicated with the communication hole 709, the water source inside the water inlet hole 707 will flow into the communication hole 709, and finally is discharged downward through the water outlet hole 622 inside the polishing wheel 621, so that when the polishing wheel 621 rotates to polish the top of the aspherical lens, the flowing water can adsorb the polished dust and flow downward into the storage water tank 3 again. At the same time, when the water source flows into the storage water tank 3, the water source can be filtered by the sliding mesh plate 626, so as to filter out the internal dust and make the water source recyclable.

[0043] When the large bevel gear 607 drives the first screw rod 608 to rotate, the first screw rod 608 can be threadedly engaged with the first screw sleeve 624, so as to drive the sliding screen plate 626 to slide inside the storage water tank 3 through the sliding rod 625. When the first screw sleeve 624 slides downward and retracts into the limit seat 5, it can drive the sliding screen plate 626 to slide upward inside the storage water tank 3, thereby filtering the dust in the water source out of the water surface, facilitating the cleaning of the dust.

After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
