Description

Technical Field

[0001] This utility model relates to the field of spectacle lens processing technology, specifically to a cutting device for spectacle lens processing. Background Technology

[0002] Eyeglass lenses are transparent materials used to correct vision, protect the eyes, and enhance aesthetics. They are usually made of optical materials such as glass or resin, and after being polished, they are assembled with eyeglass frames to form eyeglasses for people with visual impairments.

[0003] According to the Chinese patent publication number CN221818900U, "A cutting device for processing eyeglass lenses", it mainly describes how the funnel, filter screen, water pump and water pipe structure work together to collect the rinsing water after cutting eyeglass lenses, filter it, and then reuse the filtered rinsing water to rinse the lenses, thus achieving the effect of water recycling.

[0004] During the processing of eyeglass lenses, a centering instrument is used to center the lens to ensure that it does not move during grinding. Then, a grinding machine is used for rough grinding to make the lens surface smoother. Next, a polishing machine is used to polish the lens to remove minor scratches and imperfections. Finally, polishing and cleaning are performed. To improve aesthetics, some eyeglass lenses usually have a certain curvature and tilt on the bottom side of the lens to increase its recognizability. In the operation of common lens cutting machines, the lens blank is directly facing the cutting mechanism. Therefore, the special curvature and tilt on the bottom side of the lens need to be cut manually, which results in low cutting efficiency.

[0005] Therefore, a cutting device for processing eyeglass lenses is proposed to solve the problem that manual cutting is required for special curvatures and tilt angles on the bottom side of the lens, resulting in low cutting efficiency. Utility Model Content

[0006] The technical problem this invention aims to solve is that the special curvature and tilt angle of the bottom side of the lens require manual cutting, which results in low cutting efficiency. Therefore, a cutting device for processing eyeglass lenses is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows: a cutting device for processing eyeglass lenses, including a fixed plate, a protective frame, and a flip plate. A first motor is fixedly connected to the bottom side of the fixed plate, and a placement gear is fixedly connected to the output end of the first motor. A connecting frame is fixedly connected to the upper end of the placement gear. An arc-shaped groove is formed at the center of the upper end of the connecting frame. A second motor is fixedly connected to one side of the connecting frame. A rotating rod is fixedly connected to the output end of the second motor. A drive gear is fixedly connected to the rotating rod. A semi-toothed ring meshes with the drive gear. An arc-shaped groove runs through the semi-toothed ring. A pressure rod contacts the arc-shaped groove. A support plate is rotatably connected to the pressure rod. The support plate is fixedly connected to the arc-shaped groove. Connecting plates are fixedly connected to both sides of the upper end of the semi-toothed ring. A third motor is fixedly connected to the connecting plate. A grinding wheel is fixedly connected to the output end of the third motor.

[0008] As a preferred technical solution of this utility model, baffles are fixedly connected to both sides of the semi-tooth ring, and the baffles are in contact with the connecting frame. By setting the baffles, the contact between the cooling water and the semi-tooth ring is reduced.

[0009] As a preferred technical solution of this utility model, a drainage groove is provided on the bottom side of the connecting frame. The drainage groove is located at the upper end of the placement gear. By setting the drainage groove, water can be easily guided.

[0010] As a preferred technical solution of this utility model, a spring rod is engaged on one side of the trough, and the fixed end of the spring rod is located inside the fixed plate. By setting the spring rod, the placement gear can be positioned.

[0011] As a preferred technical solution of this utility model, a baffle is fixedly connected to one side of the semi-gear ring. The baffle has an arc-shaped structure and the baffle is aligned with the arc-shaped groove, which can further increase the guiding effect of cooling water and reduce the contact between cooling water and gear structure.

[0012] As a preferred technical solution of this utility model, a sliding ball is rotatably embedded in the arc-shaped groove, and the sliding ball contacts the bottom side of the baffle. By setting the sliding ball, contact support is provided for the semi-tooth ring, reducing friction.

[0013] This utility model has the following advantages: by setting a horizontally rotating placement gear on the fixed plate, in conjunction with the connecting frame and the vertically rotating half gear, the tilt angle of the grinding wheel can be adjusted, thereby facilitating the subsequent grinding and cutting of the lens, improving the grinding of special arc angles and tilt angles on the bottom side of the lens, and improving the cutting efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-3 The illustrated cutting device for processing eyeglass lenses includes a fixed plate 1, a protective frame 2, and a flip plate 3. The protective frame 2 houses a lens clamping device, consistent with current lens clamping and placement structures. The lens is then cut using a grinding wheel 13. A first motor is fixedly connected to the bottom of the fixed plate 1, driving a placement gear 4 to rotate, which in turn causes a connecting frame 5 to rotate laterally. The output end of the first motor is fixedly connected to the placement gear 4, and the upper end of the placement gear 4 is fixedly connected to the connecting frame 5. An arc-shaped groove is formed at the center of the upper end of the connecting frame 5. A second motor is fixedly connected to one side of the connecting frame 5, driving a rotating rod 6 to rotate, which in turn causes a drive gear 7 to rotate. This causes the semi-tooth ring 8 to tilt. During this process, the pressure rod 10 is located in the arc-shaped groove 9, which can maintain the stability of the rotation of the semi-tooth ring 8. The output end of the second motor is fixedly connected to the rotating rod 6, and the driving gear 7 is fixedly connected to the rotating rod 6. The semi-tooth ring 8 is meshed on the driving gear 7. The arc-shaped groove 9 runs through the semi-tooth ring 8, and the pressure rod 10 contacts the arc-shaped groove 9. The pressure rod 10 is rotatably connected to the support plate 11, and the support plate 11 is fixedly connected to the arc-shaped groove. The upper ends of the semi-tooth ring 8 are fixedly connected to both sides of the connecting plate 12, and the connecting plate 12 is fixedly connected to the third motor. The output end of the third motor is fixedly connected to the grinding wheel 13, and the third motor can drive the grinding wheel 13 to rotate.

[0020] Among them, baffles 14 are fixedly connected to both sides of the semi-tooth ring 8. The baffles 14 are in contact with the connecting frame 5. By setting the baffles 14, the contact between the cooling water and the drive gear 7 can be reduced.

[0021] The bottom side of the connecting frame 5 is provided with a drainage groove 15, which is located at the upper end of the placement gear 4. By setting the drainage groove 15, water can be easily guided.

[0022] Among them, a spring rod 16 is engaged on one side of the trough 15. The fixed end of the spring rod 16 is located inside the fixed plate 1. By setting the spring rod 16, the rotation angle of the positioning gear 4 can be limited.

[0023] Among them, a baffle 18 is fixedly connected to one side of the semi-tooth ring 8. The baffle 18 has an arc-shaped structure and corresponds to the arc-shaped groove. By setting the baffle 18, the contact between the cooling water and the semi-tooth ring 8 can be further reduced.

[0024] The arc-shaped groove contains a rotating ball 17, which contacts the bottom side of the baffle 18. By setting the ball 17, the friction between the baffle 18 and the connecting frame 5 is reduced, and support is provided.

[0025] Working principle: The lens is placed in the protective frame 2 and clamped, and then ground and cut by the lens structure on the upper side of the grinding wheel 13. After the common grinding and cutting is completed, the rotation angle of the placement gear 4 and the half-tooth ring 8 can be adjusted according to the needs of improving aesthetics. At this time, the bottom side of the lens after grinding is ground and cut by the grinding wheel 13 at an inclined angle, thereby forming a special arc angle and inclination, improving the cutting and grinding effect. During the grinding and cutting process of the lens, the baffle 18 and the cover 14 provide obstruction to reduce the contact between the cooling water spray and the gear structure, and reduce the problems of rotation effect.
